Introduction

Around the world, the number of refugees displaced by war or violence reaches over 19 million. Rates of mental health disorders, such as anxiety disorders, post-traumatic stress disorder (PTSD) and depression were higher among refugee populations in comparison to the general population. This increased vulnerability has been linked to experiences prior to migration, such as war exposure and trauma. Additionally, anxiety and other mental health disorders can manifest due to stressors post-migration, such as separation anxiety and the added load of resettlement in a new country. In general, increased rates of these disorders remain prevalent in refugee populations long after resettlement; however, some studies have shown otherwise.1

In the Karenni refugees along the Burmese-Thai border, depression and anxiety rates (41% and 42%, respectively) were higher than the average rates of depression and anxiety among the general US population (7% and 10%, respectively). These rates have been linked to traumatic events like violence, harassment, and a lack of basic needs. Moreover, the mental health of refugees is thought to be distinct from the experiences of other traumatized populations, such as veterans and sexual assault victims, due to their unique traumatic experiences as well as acculturative stress that follows the resettlement process, which features entirely new settings, practices, and a lack of familiar support systems. Furthermore, this population showed a correlation of depression and anxiety disorders with post-resettlement hardships in regards to finding employment and adapting to a new environment culturally and linguistically. In another population, 82.6% of Cambodian refugees residing in a refugee camp on the Thailand-Cambodia border self-reported depression. Fifty-five percent were confirmed by the Hopkins Symptoms Checklist to have experienced symptoms of major depression.

Symptoms of depression include changes in weight, sleep pattern, exhibiting a depressed mood for much of a day, a loss of interest in activities, lack of energy, feelings of worthlessness and guilt almost daily, lack of focus, and recurrent thoughts of death and suicide, which can include attempting or creating plans for suicide. Symptoms of PTSD include intrusion, avoidance, and hyperarousal. PTSD typically is associated with traumatic experiences. These traumatic events can include experiencing war, being held prisoner/hostage, torture and physical violence, death of a loved one, serious accidents/explosions, sexual harassment, and serious illness. Symptoms of generalized anxiety disorder include restlessness, irritability, fatigue, excessive worrying, having trouble relaxing, sleeping, and focusing.

The current refugee demographic is a highly heterogeneous group, however, there has been an increase of refugees from Arabic speaking countries in recent years. Europe, in particular, has seen a large increase of asylum applicants from Arabic speaking countries, the most frequent being Syria (35.9% of applications) and Iraq (6.9% of applications). Despite the growth of Arabic speaking refugees, few studies have investigated the mental health of these populations in recent years. The large variations in results show that the refugee population is a diverse group. Complications in studies that inhibit direct comparison between refugee populations include the use of different psychometric instruments to measure mental health.

Another factor that could promote the symptoms of PTSD, depression, and anxiety is acculturative stress. While trauma related to war negatively impacts mental health, the effects of acculturative stress on mental health among refugees resettled in Australia and Austria demonstrated that stress which accompanies the migration process can have similar effects.6 One cause of these stressors is acculturation, the process of integrating into a new culture while also maintaining one’s origin culture and identity. This process is dependent on the attitudes of both the migrant and host groups. There are inconsistencies present in existing studies investigating the effects of acculturation on mental health; however, acculturative stress in migration has been identified as a mental health risk factor.

The purpose of this review was to investigate the relationship between refugee populations and their increased vulnerability to post-traumatic stress disorder, depression, and anxiety disorders. This study also examined the factors before, during, and after the migration process associated with increased vulnerability of refugees to mental health disorders.

Refugee Health

In a particular population of Yazidi refugees, Nasiroglu et al. determined the frequency of post-traumatic stress disorder and depression among children and adolescents and examined the possible differences in experience and diagnosis between males and females. Big differences existed in the resulting diagnosis between children and adolescents. Children generally had fewer problems with mental illnesses than adolescents, who may have increased stress related to having more siblings. Adolescents had more siblings, on average, than children. Other risk factors for depression, in particular, included having older parents, being female, and witnessing someone undergoing a violent or fatal situation. In terms of gender, females of both the children and adolescent groups were significantly more likely to have an established diagnosis, as compared to males, who in general, did not have one.

To examine the mental health of Yazidi children and adolescents further, Ceri et al. investigated the presence of psychiatric disorders immediately following forced migration. Various disorders, not only PTSD, had manifested in the refugee population within the early days of resettlement. Children who experienced forced migration exhibited more behavioral and emotional problems than children who had not experienced such trauma. Following forced migration, children were observed to be very shy after their arrival to the camp and avoided contact with other children. Additionally, they communicated fears of being captured and generally did not feel safe in their new environment. Most children also had difficulty sleeping. Over one-third of the children were diagnosed with depressive disorder.

Factors that could be associated with psychiatric symptoms and disorders were torture and other traumatic events. Civilians in war-zones typically experienced at least one traumatic event due to war, and war refugees often were subjected to torture. Among Syrian Kurdish refugees, there were positive correlations between PTSD symptoms and traumatic events such as being forced to flee one’s country, witnessing violence, and confinement due to violence. Moreover, while males were more likely to experience trauma, females were more likely to have symptoms of PTSD. However, Syrian Kurdish refugees in the Kurdistan region of Iraq displayed no significant difference in the prevalence of PTSD among males and females, which may be a result of cultural differences.

Refugee populations who have experienced traumatic events often are vulnerable to increased symptoms if they experience another stressful event. Thus, it has been investigated whether new traumatic or stressful events affect mental health of an already PTSD diagnosed individual. Schock et al. studied refugees from Iran, the Balkan region, and Turkey. All participants were diagnosed with PTSD. Groups that experienced a new significant life event displayed increased avoidance behavior. Such behavior may be a mechanism for these individuals to avoid re-experiencing their past trauma. Additionally, stressful life events affected symptoms more than traumatic life events. Overall, new significant life events resulted in a significant increase in PTSD symptoms, especially avoidance.

Furthermore, refugees diagnosed with PTSD often were diagnosed with secondary psychotic features as well. Nygaard et al. found 74 of 181 refugees (41%) diagnosed with PTSD were identified to have secondary psychotic features. These secondary psychotic features included hallucinations and delusions, and the impact of these features can make PTSD with Secondary Psychotic features (PTSD-SP) a burdening disorder. Refugees are uniquely vulnerable to developing secondary psychotic features with PTSD, as these features are assumed to manifest because refugees usually are subjected to more long-term trauma than other PTSD patients. Moreover, refugee populations often lack familiar support systems as they seek asylum abroad to escape their threatening situations, exacerbating the problem.

Prior to Migration

Prior to the migration process, there are environmental factors that can be associated with the development of mental disorders. In Ethiopian immigrants and refugees, rates of depression were significantly higher among individuals who experienced pre-migration trauma as well as internment in a refugee camp. Other factors, like witnessing death in a family and lacking resources such as water, shelter, and food, were associated with depression. Individuals who experienced more traumatic events were more vulnerable to depression, as trauma can lead to hopelessness and a loss of interest in activities. In North Korea, war and organized violence are not the primary reason for individuals to seek asylum, rather they often are trying to escape political oppression. Nevertheless, the traumatic experiences, such as torture, violence, imprisonment, and witnessing death, are shared.

In a group of North Korean refugees, insomnia, often associated with depressive and post-traumatic stress symptoms, was higher in those individuals who had experienced traumatic events prior to migration. These findings suggested that development of refugee insomnia could be associated with these traumatic experiences. A study of Syrian refugees in Turkey found that other factors could contribute to the development of PTSD, like being diagnosed with a psychiatric disorder in the past or having a family history of psychiatric disorder, along with experiencing trauma. Refugees face major obstacles to meet health care needs, along with trauma and prior diagnoses, while in war zones or areas affected by natural disasters.

During Migration

During migration, there are other stressors that can be associated with depression and anxiety. Stress can be from an uncertainty in the future, as is typical of asylum seekers. In two Danish asylum centers, the mental health of rejected Iraqi asylum seekers was evaluated. In this group, the prevalence of anxiety symptoms was 94% and depression symptoms had a prevalence of 100%. The lengths of stay in the asylum centers, as well as the number of traumatic events, were thought to be risk factors associated with psychological distress.

Among those in refugee camps, daily stressors can exacerbate mental problems, such as lacking basic necessities, restricted movement, and continued concern for safety, as refugee camps are only short-term solutions. Consistency in the life of refugees can ease mental distress. For example, the prevalence of PTSD was lower than expected in a group of Syrian child refugees, perhaps because these children travelled with at least one parent, transferring a crucial part of the child’s psychosocial environment. Therefore, having a parent accompany children during travel in the migration process could be a protective factor that can reduce post-traumatic stress rates among some children. Additionally, a successful flight during migration was associated with creating feelings of hope for the future. However, the anxiety of the parent accompanying the child can also influence the child’s own anxiety, therefore, the presence of a parent may not always be favorable especially if parents have mental distress.

Post-Migration

Often, depression among refugees has long-term effects. A study of Guatemalan refugees in Mexico found a 38.8% lifetime prevalence of depression. Karenina refugees settled on the Thai-Burma border had a lifetime depression prevalence of 41.8%. Post-migration stress can be related to feelings of insecurity. A group of North Korean refugees settled in South Korea felt unsafe due to a fear of being arrested and deported back to North Korea. Post-migration mental distress also has been associated with acculturative stress. Refugees were about ten times more likely to have PTSD than the host country’s general population, illustrating that the mental distress in refugee populations does not disappear after resettlement. These PTSD rates were among 7,000 refugees resettled in western countries. The comparison of refugees with the general population may not be reflective of the whole picture, with need to compare refugee rates with other populations including veterans and/or domestic violence victims in future studies.

Acculturation is the process of integrating oneself into a new culture while maintaining one’s origin culture and identity. This process can create a considerable amount of stress for new refugees trying to restart lives in new countries, often resulting in anxiety and depression, as well as the exacerbation of post-traumatic stress. Acculturative stress is based on the demands of immigration experience. It is related to experiences that cause stress among immigrants and refugees. These include unfamiliarity with daily tasks, difficulties in finding employment, learning the host country’s language, discrimination, and a feeling of not belonging in one’s new environment. As an example of overcoming language barriers and its effect on mental health, Bosnian refugees living in Australia reported significantly more stress in terms of accommodating to the host language than Bosnian refugees living in Austria. Acculturative stress affects mental health based on the social atmosphere a refugee experiences in a host country, indicated by immigration policies and the general attitude of the host society towards refugees and different cultures.

Discussion and Conclusion

Refugee populations have an increased vulnerability to post-traumatic stress disorder, depression, and anxiety due to their exposure to traumatic experiences prior to migration. Prior to the migration process, refugees often experience trauma from organized violence and political oppression, which can include the death of a loved one, torture, imprisonment, witnessing public executions, and lacking basic necessities. Other risk factors prior to migration include previous diagnoses of psychiatric disorders in oneself and/or family members. The development of such disorders can happen regardless of age; however, some age groups may experience more intense symptoms than others. Children in particular can develop behavioral and emotional problems as a result of certain traumatic experiences they may face, including forced migration. However, adolescents were more likely to have PTSD, which could be related to risk factors such as having more siblings or older parents, among others.

Studies varied in regards to showing differences in the manifestation of mental distress between males and females. Nasiroglu et al., however, showed being female as a risk factor for depression. Females were more likely than males to have an established mental health diagnosis. In relation to PTSD, women were more likely to exhibit PTSD symptoms; however, this has not been consistent when the prevalence of PTSD was investigated among some Syrian Kurdish refugees, possibly due to culture differences. Nevertheless, being female generally was associated with increased prevalence of mental distress.

During the migration period, there were several factors that contributed to mental distress, such as lingering feelings of unsafety and uncertainty in the future. Prevalence rates of depression and anxiety among refugee populations who were denied asylum were high. A protective factor that helps when migrating with children is maintaining some aspects of a refugee’s previous environment, such as ensuring the child travels with at least one parent.

Post-migration can include many difficulties that can cause mental distress to be worsened and/or have a long-term presence of mental health symptoms. A common factor associated with mental distress post-migration is acculturative stress, often experienced by refugees and immigrants. Experiences that result in acculturative stress include unfamiliarity with daily tasks, overcoming language barriers, and facing discrimination, among others. Acculturative stress often is unique to one’s environment because of the attitudes of the host country and whether certain changes in environment, such as language, are great. Not only are refugee populations vulnerable to PTSD, but they also face secondary features with their PTSD, increasing the burden of the mental disorder. These features can include hallucinations and delusions. Refugees are uniquely vulnerable to these secondary features because of their more long-term trauma. They are thrust into unfamiliar environments and lack familiar support systems. Consequently, refugees with PTSD are likely to experience secondary psychotic symptoms as well.

This review article highlighted the higher prevalence rates of mental health disorders among refugees, especially depression, anxiety, and PTSD, who have experienced trauma and forced migration from their regions/countries. It underscored the importance of managing mental health scars and disorders with great empathy and higher level of care. Possible scenarios to help include, but are not limited to, involving family members in their care, language interpreters, being patient with them, and establishing an inclusive environment that accounts for the psycho-socio-cultural aspects of refugee lives. Comparing refugees with the general population may not be reflective of whole picture. Therefore, further need exists to compare refugee mental health rates with other populations including veterans, domestic violence victims, and/or other violence victims in future studies.

There are few studies available on mental health issues in the refugee population, possibly due to a lack of funding in this clinical arena. Moreover, few studies have mentioned potential errors in reporting data due to inability of the refugees to report their symptoms accurately under moderate to severe mental distress. More studies are needed to examine the increased vulnerability of refugee populations to mental health disorder and management guidelines to integrate them better and more fully into a new host society.

Introduction

Across the globe, over 19 million people have become refugees due to war or violence. These refugee groups often experience higher rates of mental health issues like anxiety, post-traumatic stress disorder (PTSD), and depression compared to the general population. This increased risk is linked to difficult experiences before migration, such as exposure to war and trauma. Stress after migration, like being separated from loved ones or adapting to a new country, can also lead to anxiety and other mental health problems. While high rates of these disorders often remain in refugee populations long after they resettle, some studies have shown different results.

For Karenni refugees living near the Burmese-Thai border, rates of depression and anxiety were 41% and 42% respectively. These rates are much higher than the average in the general US population (7% for depression and 10% for anxiety). These issues are linked to traumatic events like violence, harassment, and not having basic necessities. The mental health challenges of refugees are considered unique compared to other traumatized groups, such as veterans or sexual assault victims. This is due to their specific traumatic experiences and the stress of adjusting to a new culture after resettlement, which involves entirely new surroundings, customs, and a lack of familiar support. Furthermore, this group showed a link between depression and anxiety and difficulties faced after resettlement, such as finding jobs and adapting to new cultures and languages. In another example, 82.6% of Cambodian refugees in a camp on the Thailand-Cambodia border reported feeling depressed, and 55% were confirmed to have major depression symptoms using a specific checklist.

Symptoms of depression include changes in weight or sleep, a consistently sad mood, loss of interest in activities, low energy, daily feelings of worthlessness and guilt, difficulty focusing, and repeated thoughts of death or suicide, including attempts or plans. PTSD symptoms include flashbacks, avoiding reminders of the trauma, and being easily startled. PTSD is typically linked to traumatic events such as war, being held captive, torture, physical violence, the death of a loved one, serious accidents, sexual harassment, or severe illness. Symptoms of generalized anxiety disorder include restlessness, irritability, tiredness, excessive worry, and difficulty relaxing, sleeping, and focusing.

Refugee populations are very diverse. However, there has been an increase in refugees from Arabic-speaking countries recently. Europe, in particular, has seen a rise in asylum seekers from these nations, primarily Syria (35.9% of applications) and Iraq (6.9%). Despite this growth, few recent studies have looked into the mental health of these specific populations. The wide range of study results shows that the refugee population is indeed a varied group. Challenges in these studies, such as using different tools to measure mental health, make it hard to compare findings directly across refugee groups.

Acculturative stress can also worsen symptoms of PTSD, depression, and anxiety. While trauma from war negatively affects mental health, the stress of adapting to a new culture during migration can have similar effects, as seen in refugees resettled in Australia and Austria. Acculturation is the process of fitting into a new culture while also keeping one's original culture and identity. This process depends on the attitudes of both the migrant and the host community. Studies on how acculturation affects mental health have shown inconsistent results, but acculturative stress during migration is recognized as a risk factor for mental health problems.

This review aimed to explore why refugee populations are more likely to experience PTSD, depression, and anxiety disorders. The study also examined factors before, during, and after migration that contribute to this increased risk of mental health disorders in refugees.

Refugee Health

In a specific group of Yazidi refugees, researchers investigated how often children and adolescents experienced PTSD and depression, and whether there were differences between males and females. There were notable differences in diagnoses between children and adolescents. Children generally had fewer mental health problems than adolescents, who might have felt more stress due to having more siblings. On average, adolescents had more siblings than children. Other factors increasing the risk for depression included having older parents, being female, and witnessing violent or fatal events. Regarding gender, females in both child and adolescent groups were significantly more likely to receive a diagnosis compared to males, who generally did not.

To further understand the mental health of Yazidi children and adolescents, another study looked at psychiatric disorders immediately after forced migration. Various disorders, not just PTSD, appeared in the refugee population soon after resettlement. Children who experienced forced migration showed more behavioral and emotional problems than those who had not. After arriving at the camp following forced migration, children were observed to be very shy and avoided contact with others. They also expressed fears of being captured and generally did not feel safe in their new surroundings. Most children also had difficulty sleeping. More than one-third of the children were diagnosed with depressive disorder.

Torture and other traumatic events can be linked to psychiatric symptoms and disorders. Civilians in war zones typically experience at least one traumatic event, and war refugees are often subjected to torture. Among Syrian Kurdish refugees, there was a clear link between PTSD symptoms and traumatic events like being forced to leave their country, witnessing violence, and being confined due to violence. While males were more likely to experience trauma, females were more likely to show PTSD symptoms. However, Syrian Kurdish refugees in the Kurdistan region of Iraq showed no significant difference in PTSD rates between males and females, which might be due to cultural differences.

Refugee populations who have already experienced traumatic events are often more vulnerable to increased symptoms if they encounter another stressful event. Thus, researchers have investigated whether new traumatic or stressful events affect the mental health of individuals already diagnosed with PTSD. One study focused on refugees from Iran, the Balkan region, and Turkey, all of whom had PTSD. Groups that experienced a new significant life event showed more avoidance behavior. This behavior might be a way for these individuals to avoid re-experiencing past trauma. Additionally, stressful life events had a greater impact on symptoms than traumatic life events. Overall, new significant life events led to a significant increase in PTSD symptoms, particularly avoidance.

Furthermore, refugees diagnosed with PTSD were often also diagnosed with secondary psychotic features. One study found that 74 out of 181 refugees (41%) with PTSD also had secondary psychotic features, which include hallucinations and delusions. The impact of these features can make PTSD with secondary psychotic features (PTSD-SP) a very challenging disorder. Refugees are uniquely prone to developing these features with PTSD because they often endure longer-term trauma than other PTSD patients. Moreover, refugee populations often lack familiar support systems when they seek asylum abroad to escape dangerous situations, which worsens the problem.

Prior to Migration

Before migration, environmental factors can contribute to the development of mental disorders. Among Ethiopian immigrants and refugees, depression rates were significantly higher in those who experienced trauma before migration and those who were held in a refugee camp. Other factors, such as witnessing death in the family and lacking basic necessities like water, shelter, and food, were linked to depression. Individuals who experienced more traumatic events were more susceptible to depression, as trauma can lead to feelings of hopelessness and a loss of interest in activities. In North Korea, war and organized violence are not the main reasons individuals seek asylum; instead, they often escape political oppression. Nevertheless, traumatic experiences like torture, violence, imprisonment, and witnessing death are common.

Among a group of North Korean refugees, insomnia, often linked to symptoms of depression and PTSD, was more common in individuals who had experienced traumatic events before migration. These findings suggest that the development of refugee insomnia could be connected to these traumatic experiences. A study of Syrian refugees in Turkey found that other factors could contribute to PTSD, such as a past diagnosis of a psychiatric disorder or a family history of psychiatric disorders, in addition to experiencing trauma. Refugees face significant challenges in meeting healthcare needs, along with trauma and prior diagnoses, while living in war zones or areas affected by natural disasters.

During Migration

During migration, additional stressors can lead to depression and anxiety. Uncertainty about the future, common for asylum seekers, can cause stress. In two Danish asylum centers, the mental health of rejected Iraqi asylum seekers was assessed. In this group, 94% showed symptoms of anxiety, and 100% showed symptoms of depression. The length of stay in the asylum centers and the number of traumatic events were believed to be risk factors for psychological distress.

In refugee camps, daily stressors can worsen mental health problems. These include not having basic necessities, restricted movement, and ongoing safety concerns, as refugee camps are only short-term solutions. Consistency in the lives of refugees can help reduce mental distress. For example, a group of Syrian child refugees had lower-than-expected rates of PTSD. This might be because these children traveled with at least one parent, which maintained a crucial part of their social and emotional environment. Therefore, a parent accompanying children during migration could be a protective factor that reduces PTSD rates among some children. Additionally, a successful journey during migration was associated with feelings of hope for the future. However, a parent's anxiety can also affect a child's anxiety, so a parent's presence may not always be beneficial, especially if the parent is experiencing mental distress.

Post-Migration

Depression among refugees often has long-lasting effects. A study of Guatemalan refugees in Mexico found that 38.8% experienced depression at some point in their lives. Karenina refugees settled on the Thai-Burma border had a lifetime depression prevalence of 41.8%. Stress after migration can be related to feelings of insecurity. A group of North Korean refugees settled in South Korea felt unsafe due to fears of being arrested and deported back to North Korea. Mental distress after migration has also been linked to acculturative stress. Refugees were about ten times more likely to have PTSD than the general population of their host country, showing that mental distress in refugee populations does not disappear after resettlement. These PTSD rates were observed among 7,000 refugees resettled in Western countries. Comparing refugees only with the general population might not show the full picture, and future studies should compare refugee rates with other populations, such as veterans or victims of domestic violence.

Acculturation is the process of fitting into a new culture while keeping one's original culture and identity. This process can create significant stress for new refugees trying to rebuild their lives in new countries, often leading to anxiety and depression, and worsening post-traumatic stress. Acculturative stress arises from the demands of the immigration experience. It is related to experiences that cause stress for immigrants and refugees, such as being unfamiliar with daily tasks, struggling to find employment, learning the host country's language, facing discrimination, and feeling like one does not belong in the new environment. For example, Bosnian refugees living in Australia reported significantly more stress adapting to the host language than Bosnian refugees living in Austria. Acculturative stress affects mental health based on the social environment a refugee experiences in a host country, influenced by immigration policies and the general attitude of the host society towards refugees and different cultures.

Discussion and Conclusion

Refugee populations are more likely to experience PTSD, depression, and anxiety because they are exposed to traumatic events before migration. Before migration, refugees often face trauma from organized violence and political oppression, which can include the death of loved ones, torture, imprisonment, witnessing public executions, and lacking basic necessities. Other risk factors before migration include previous diagnoses of psychiatric disorders in the individual or their family members. These disorders can develop at any age, but some age groups may experience more intense symptoms. Children, in particular, can develop behavioral and emotional problems from specific traumatic experiences, such as forced migration. However, adolescents were more likely to have PTSD, which could be linked to factors like having more siblings or older parents.

Studies have varied in showing differences in mental distress between males and females. However, one study indicated that being female was a risk factor for depression, with females being more likely than males to receive a mental health diagnosis. Regarding PTSD, women were more likely to show symptoms, though this has not been consistent among some Syrian Kurdish refugees, possibly due to cultural differences. Nevertheless, being female was generally linked to a higher prevalence of mental distress.

During migration, several factors contributed to mental distress, such as ongoing feelings of unsafety and uncertainty about the future. Rates of depression and anxiety were high among refugee populations whose asylum applications were denied. A protective factor for children during migration is maintaining some aspects of a refugee's previous environment, such as ensuring the child travels with at least one parent.

The period after migration can involve many difficulties that can worsen mental distress or lead to long-term mental health symptoms. A common factor linked to mental distress after migration is acculturative stress, often experienced by refugees and immigrants. Experiences that cause acculturative stress include being unfamiliar with daily tasks, overcoming language barriers, and facing discrimination. Acculturative stress is often unique to a specific environment due to the attitudes of the host country and the extent of changes in the environment, such as language differences. Refugee populations are not only vulnerable to PTSD but also experience secondary features with their PTSD, which increases the burden of the disorder. These features can include hallucinations and delusions. Refugees are uniquely vulnerable to these secondary features because they often endure longer-term trauma. They are placed in unfamiliar environments and lack familiar support systems. Consequently, refugees with PTSD are likely to experience secondary psychotic symptoms.

This review highlighted the higher rates of mental health disorders, especially depression, anxiety, and PTSD, among refugees who have experienced trauma and forced migration from their regions or countries. It emphasized the importance of addressing mental health challenges and disorders with great empathy and a higher level of care. Possible ways to help include involving family members in their care, using language interpreters, being patient, and creating an inclusive environment that considers the psychological, social, and cultural aspects of refugees' lives. Comparing refugees only with the general population might not show the complete picture. Therefore, more studies are needed to compare refugee mental health rates with other populations, such as veterans, victims of domestic violence, or other victims of violence.

Few studies are available on mental health issues in refugee populations, possibly due to a lack of funding in this clinical area. Additionally, few studies have mentioned potential errors in data reporting due to refugees' inability to accurately report their symptoms while experiencing moderate to severe mental distress. More research is needed to examine the increased vulnerability of refugee populations to mental health disorders and to develop management guidelines to help them integrate better and more fully into a new host society.

Introduction

Globally, over 19 million people are refugees due to war or violence. These populations show higher rates of mental health conditions like anxiety, post-traumatic stress disorder (PTSD), and depression compared to the general population. This increased risk is linked to experiences before migration, such as exposure to war and trauma. Stress after migration, including separation from family and the challenges of settling in a new country, can also lead to anxiety and other mental health problems. Generally, these disorders continue to be common in refugee communities long after they have settled, though some research presents different findings.

Among Karenni refugees along the Burmese-Thai border, depression and anxiety rates were 41% and 42% respectively. These figures are much higher than the average rates in the general US population (7% for depression and 10% for anxiety). These elevated rates are linked to traumatic events such as violence, harassment, and not having basic needs met. The mental health experiences of refugees are considered distinct from other traumatized groups, like veterans or sexual assault survivors. This difference is due to the unique traumas refugees face, as well as the stress of adapting to a new culture during resettlement. This process involves entirely new surroundings, customs, and a lack of familiar support. Studies have also shown a connection between depression and anxiety disorders in this population and post-resettlement difficulties, such as finding work and adjusting to a new culture and language. In another example, 82.6% of Cambodian refugees in a camp on the Thailand-Cambodia border reported feeling depressed. Of these, 55% were confirmed to have symptoms of major depression using a standard screening tool.

Symptoms of depression include changes in weight or sleep patterns, a depressed mood most of the day, loss of interest in activities, low energy, daily feelings of worthlessness and guilt, difficulty concentrating, and repeated thoughts of death or suicide, including attempts or planning. PTSD symptoms involve re-experiencing the trauma, avoiding things connected to the trauma, and being overly alert or reactive. PTSD is typically linked to traumatic events, such as war, being held captive, torture, physical violence, the death of a loved one, serious accidents, sexual harassment, or severe illness. Symptoms of generalized anxiety disorder include restlessness, irritability, fatigue, excessive worry, and difficulty relaxing, sleeping, or focusing.

The current refugee population is very diverse, but there has been an increase in refugees from Arabic-speaking countries in recent years. Europe, in particular, has seen a significant rise in asylum seekers from these nations, with Syria (35.9% of applications) and Iraq (6.9% of applications) being the most common. Despite this increase, few recent studies have explored the mental health of these specific populations. The wide range of results in existing research highlights the diversity of refugee groups. Challenges in these studies, such as using different tools to measure mental health, make direct comparisons between refugee populations difficult.

Another factor that can worsen symptoms of PTSD, depression, and anxiety is acculturative stress. While trauma from war negatively impacts mental health, the stress that comes with the migration process can have similar effects. This was observed in studies of refugees settled in Australia and Austria. One cause of these stressors is acculturation, which is the process of integrating into a new culture while also keeping one's original culture and identity. This process depends on the attitudes of both the migrant and the host community. Existing research on how acculturation affects mental health has shown conflicting results; however, acculturative stress during migration has been identified as a risk factor for mental health problems.

This review aimed to examine the link between refugee populations and their increased risk for post-traumatic stress disorder, depression, and anxiety disorders. The study also looked at factors before, during, and after migration that are connected to this heightened vulnerability to mental health disorders in refugees.

Refugee Health

In a specific group of Yazidi refugees, researchers studied how often PTSD and depression occurred among children and adolescents, and whether there were differences between males and females. There were significant differences in diagnoses between age groups. Children generally had fewer mental health problems than adolescents, who might experience more stress due to having more siblings. Adolescents had more siblings on average than children. Other risk factors for depression included having older parents, being female, and witnessing a violent or fatal event. Regarding gender, females in both child and adolescent groups were much more likely to have a mental health diagnosis compared to males, who generally did not.

To further investigate the mental health of Yazidi children and adolescents, another study looked at psychiatric disorders immediately after forced migration. Various disorders, not just PTSD, appeared in the refugee population soon after resettlement. Children who had experienced forced migration showed more behavioral and emotional problems than children who had not. Following forced migration, children were observed to be very shy upon arrival at the camp and avoided contact with other children. They also expressed fears of being captured and generally did not feel safe in their new surroundings. Most children also had difficulty sleeping. More than a third of the children were diagnosed with a depressive disorder.

Factors that could be linked to psychiatric symptoms and disorders include torture and other traumatic events. Civilians in war zones typically experience at least one traumatic event due to war, and war refugees are often subjected to torture. Among Syrian Kurdish refugees, there was a clear link between PTSD symptoms and traumatic events like being forced to leave their country, witnessing violence, and being confined due to violence. While males were more likely to experience trauma, females were more likely to have symptoms of PTSD. However, Syrian Kurdish refugees in the Kurdistan region of Iraq showed no significant difference in the occurrence of PTSD between males and females, which might be due to cultural differences.

Refugee populations who have experienced trauma are often more vulnerable to increased symptoms if they experience another stressful event. Thus, researchers have investigated whether new traumatic or stressful events affect the mental health of individuals already diagnosed with PTSD. One study examined refugees from Iran, the Balkan region, and Turkey, all of whom had a PTSD diagnosis. Groups that experienced a new significant life event showed more avoidance behaviors. Such behavior may be a way for these individuals to avoid re-experiencing their past trauma. Additionally, stressful life events had a greater impact on symptoms than traumatic life events. Overall, new significant life events led to a notable increase in PTSD symptoms, particularly avoidance.

Furthermore, refugees diagnosed with PTSD often also received diagnoses for secondary psychotic features. One study found that 74 out of 181 refugees (41%) diagnosed with PTSD also had secondary psychotic features. These features include hallucinations and delusions, and their impact can make PTSD with Secondary Psychotic features (PTSD-SP) a very challenging disorder. Refugees are particularly susceptible to developing secondary psychotic features with PTSD, as these features are thought to arise because refugees typically experience longer-term trauma than other PTSD patients. Moreover, refugee populations often lack familiar support systems when they seek asylum abroad to escape threatening situations, which makes the problem worse.

Prior to Migration

Before the migration process, certain environmental factors can be linked to the development of mental disorders. In Ethiopian immigrants and refugees, rates of depression were significantly higher among individuals who experienced trauma before migration and those who were held in a refugee camp. Other factors, such as witnessing death in the family and lacking basic resources like water, shelter, and food, were also linked to depression. Individuals who experienced more traumatic events were more susceptible to depression, as trauma can lead to feelings of hopelessness and a loss of interest in activities. In North Korea, war and organized violence are not the main reasons individuals seek asylum; instead, they often try to escape political oppression. Nevertheless, traumatic experiences, such as torture, violence, imprisonment, and witnessing death, are common.

Among a group of North Korean refugees, insomnia, which is often linked to symptoms of depression and post-traumatic stress, was more common in individuals who had experienced traumatic events before migration. These findings suggest that the development of refugee insomnia could be connected to these traumatic experiences. A study of Syrian refugees in Turkey found that other factors could contribute to the development of PTSD, such as a past diagnosis of a psychiatric disorder or a family history of such disorders, in addition to experiencing trauma. Refugees face significant challenges in meeting their healthcare needs, along with trauma and previous diagnoses, while in war zones or areas affected by natural disasters.

During Migration

During migration, other stressors can be linked to depression and anxiety. Stress can arise from uncertainty about the future, which is typical for asylum seekers. In two Danish asylum centers, the mental health of rejected Iraqi asylum seekers was assessed. In this group, the occurrence of anxiety symptoms was 94%, and depression symptoms were present in 100%. The length of stay in the asylum centers, along with the number of traumatic events experienced, were considered risk factors associated with psychological distress.

For individuals in refugee camps, daily stressors can worsen mental problems. These include not having basic necessities, restricted movement, and ongoing safety concerns, as refugee camps are only temporary solutions. Consistency in the lives of refugees can help reduce mental distress. For instance, the rate of PTSD was lower than expected in a group of Syrian child refugees, possibly because these children traveled with at least one parent, which provided a crucial part of the child's familiar environment. Therefore, having a parent accompany children during migration could be a protective factor that reduces post-traumatic stress rates among some children. Additionally, a successful journey during migration was associated with creating feelings of hope for the future. However, the anxiety of a parent accompanying a child can also influence the child's own anxiety; thus, a parent's presence may not always be beneficial, especially if the parents are experiencing mental distress.

Post-Migration

Depression among refugees often has long-term effects. A study of Guatemalan refugees in Mexico found that 38.8% had experienced depression at some point in their lives. Karenina refugees settled on the Thai-Burma border had a lifetime depression prevalence of 41.8%. Stress after migration can be related to feelings of insecurity. A group of North Korean refugees settled in South Korea felt unsafe due to a fear of being arrested and deported back to North Korea. Mental distress after migration has also been linked to acculturative stress. Refugees were about ten times more likely to have PTSD than the general population of their host country, showing that mental distress in refugee populations does not disappear after resettlement. These PTSD rates were observed among 7,000 refugees settled in Western countries. Comparing refugees only to the general population may not provide a complete picture, indicating a need for future studies to compare refugee rates with other populations, such as veterans or victims of domestic violence.

Acculturation is the process of integrating into a new culture while maintaining one's original culture and identity. This process can create significant stress for new refugees trying to rebuild their lives in new countries, often leading to anxiety and depression, and worsening existing post-traumatic stress. Acculturative stress arises from the challenges of the immigration experience. It is related to experiences that cause stress among immigrants and refugees, including unfamiliarity with daily tasks, difficulties finding employment, learning the host country's language, discrimination, and a feeling of not belonging in their new environment. For example, Bosnian refugees living in Australia reported significantly more stress related to adapting to the host language than Bosnian refugees living in Austria. Acculturative stress affects mental health based on the social environment a refugee experiences in a host country, which is influenced by immigration policies and the general attitude of the host society towards refugees and different cultures.

Discussion and Conclusion

Refugee populations face a heightened risk of post-traumatic stress disorder, depression, and anxiety due to their exposure to traumatic experiences before migration. Before migrating, refugees often endure trauma from organized violence and political oppression, which can include the death of loved ones, torture, imprisonment, witnessing public executions, and lacking basic necessities. Other risk factors prior to migration include having previous diagnoses of psychiatric disorders oneself or a family history of such disorders. These disorders can develop at any age, though some age groups may experience more intense symptoms. Children, in particular, can develop behavioral and emotional problems from specific traumatic experiences, including forced migration. However, adolescents were more likely to have PTSD, potentially linked to risk factors like having more siblings or older parents.

Studies varied in showing differences in how mental distress appears between males and females. However, one study indicated that being female was a risk factor for depression, with females more likely than males to have an established mental health diagnosis. Regarding PTSD, women were more likely to show symptoms; however, this finding was not consistent when PTSD prevalence was examined among some Syrian Kurdish refugees, possibly due to cultural differences. Nevertheless, being female was generally linked to a higher prevalence of mental distress.

During migration, several factors contributed to mental distress, such as ongoing feelings of insecurity and an uncertain future. Rates of depression and anxiety were high among refugee populations whose asylum applications were denied. A protective factor for children during migration is maintaining some aspects of their previous environment, such as ensuring the child travels with at least one parent.

The period after migration can involve many difficulties that can worsen mental distress or lead to long-term mental health symptoms. A common factor linked to mental distress post-migration is acculturative stress, often experienced by refugees and immigrants. Experiences that result in acculturative stress include unfamiliarity with daily tasks, challenges in overcoming language barriers, and facing discrimination. Acculturative stress is often specific to one's environment due to the attitudes of the host country and the extent of environmental changes, such as language. Not only are refugee populations vulnerable to PTSD, but they also experience secondary features with their PTSD, increasing the burden of the mental disorder. These features can include hallucinations and delusions. Refugees are uniquely susceptible to these secondary features because they often experience longer-term trauma. They are placed into unfamiliar environments and lack familiar support systems. As a result, refugees with PTSD are likely to experience secondary psychotic symptoms.

This review highlighted the higher rates of mental health disorders among refugees, particularly depression, anxiety, and PTSD, especially for those who have experienced trauma and forced migration. It emphasized the importance of addressing mental health impacts and disorders with significant empathy and a higher level of care. Possible ways to help include involving family members in their care, providing language interpreters, being patient with them, and creating an inclusive environment that considers the psychological, social, and cultural aspects of refugees' lives. Comparing refugees solely with the general population may not fully represent the situation. Therefore, there is a further need to compare refugee mental health rates with other populations, including veterans, victims of domestic violence, or other victims of violence, in future studies.

Few studies are available on mental health issues in the refugee population, possibly due to a lack of funding in this clinical area. Moreover, few studies have mentioned potential errors in data reporting due to refugees' inability to accurately describe their symptoms under moderate to severe mental distress. More research is needed to examine the increased vulnerability of refugee populations to mental health disorders and to develop management guidelines for their better and more complete integration into new host societies.

Introduction

Many refugees around the world, over 19 million, have been forced from their homes due to war or violence. These groups often experience higher rates of mental health conditions like anxiety, post-traumatic stress disorder (PTSD), and depression. This increased risk is linked to difficult experiences before migration, such as exposure to war and other traumas. Stress after migration, like being separated from family or the challenges of settling in a new country, can also lead to anxiety and other mental health issues. While these problems often remain long after refugees resettle, some studies have shown different outcomes.

Among Karenni refugees living near the Burmese-Thai border, depression rates were 41% and anxiety rates were 42%. These figures are much higher than the average rates in the general US population, which are 7% for depression and 10% for anxiety. These high rates have been connected to traumatic events like violence, harassment, and not having basic necessities. The mental health struggles of refugees are also thought to be different from those of other traumatized groups, like veterans or victims of sexual assault. This is because refugees face unique traumatic experiences and also deal with the stress of adjusting to a new culture, which involves completely new environments, customs, and a lack of familiar support systems. Additionally, for this group, depression and anxiety were linked to difficulties after resettlement, such as finding jobs and adapting to new cultural and language differences. In another example, 82.6% of Cambodian refugees in a camp on the Thailand-Cambodia border reported feeling depressed, and 55% were confirmed to have major depression symptoms using a specific checklist.

Symptoms of depression can include changes in weight or sleep patterns, feeling sad for most of the day, losing interest in activities, having low energy, feeling worthless or guilty almost daily, difficulty concentrating, and recurring thoughts of death or suicide, which may involve attempts or planning. PTSD symptoms involve re-experiencing the trauma, avoiding things related to it, and being overly alert or easily startled. PTSD is typically linked to traumatic experiences such as war, being held captive, torture, physical violence, the death of a loved one, serious accidents, sexual harassment, or severe illness. Symptoms of generalized anxiety disorder include restlessness, irritability, tiredness, excessive worrying, and trouble relaxing, sleeping, or focusing.

Currently, refugees come from many different backgrounds, but there has been a recent increase in those from Arabic-speaking countries. Europe, in particular, has seen a large rise in asylum applications from these areas, with Syria accounting for 35.9% and Iraq 6.9% of applications. Despite this increase, few recent studies have explored the mental health of Arabic-speaking refugee populations. The wide range of study results shows that the refugee population is very diverse, and differences in the tools used to measure mental health in these studies make direct comparisons difficult.

Another factor that can worsen symptoms of PTSD, depression, and anxiety is acculturative stress. While war-related trauma negatively affects mental health, studies on refugees in Australia and Austria showed that the stress of adapting to a new culture during migration can have similar negative effects. Acculturation is the process of blending into a new culture while also keeping one's original culture and identity. This process depends on the attitudes of both the refugee and the host community. Although existing studies on how acculturation affects mental health show conflicting results, acculturative stress during migration has been identified as a risk factor for mental health problems.

This review aimed to explore why refugee populations are more vulnerable to PTSD, depression, and anxiety disorders. It also examined the factors before, during, and after migration that contribute to this increased risk of mental health conditions.

Refugee Health

Among a specific group of Yazidi refugees, research found out how often children and adolescents had PTSD and depression. It also looked at how these conditions might differ between males and females. There were clear differences in diagnoses between children and adolescents. Children generally had fewer mental health problems than adolescents, who might have more stress due to having more siblings. Adolescents had more siblings on average than children. Other risk factors for depression included having older parents, being female, and seeing someone experience a violent or deadly situation. Regarding gender, females in both child and adolescent groups were much more likely to have a diagnosed mental health condition compared to males.

To further understand the mental health of Yazidi children and adolescents, another study investigated the psychiatric disorders that appeared right after forced migration. Various disorders, not just PTSD, were seen in the refugee population soon after they resettled. Children who had been forced to migrate showed more behavioral and emotional problems than those who had not experienced such trauma. After arriving at the camp, these children were observed to be very shy and avoided contact with other children. They also expressed fears of being captured and generally did not feel safe in their new environment. Most children also had difficulty sleeping. Over one-third of these children were diagnosed with a depressive disorder.

Factors that could be linked to psychiatric symptoms and disorders include torture and other traumatic events. People living in war zones typically experience at least one traumatic event due to war, and war refugees often endure torture. Among Syrian Kurdish refugees, there was a clear link between PTSD symptoms and traumatic events like being forced to leave their country, witnessing violence, and being confined due to violence. While males were more likely to experience trauma, females were more likely to show symptoms of PTSD. However, Syrian Kurdish refugees in the Kurdistan region of Iraq showed no significant difference in PTSD rates between males and females, which might be due to cultural differences.

Refugee populations who have experienced traumatic events are often more vulnerable to worsened symptoms if they face another stressful event. Therefore, researchers have studied whether new traumatic or stressful events affect the mental health of individuals already diagnosed with PTSD. One study looked at refugees from Iran, the Balkan region, and Turkey, all of whom had PTSD. Groups that experienced a new significant life event showed increased avoidance behavior. This behavior might be a way for these individuals to avoid re-experiencing their past trauma. Additionally, stressful life events had a greater impact on symptoms than traumatic life events. Overall, new significant life events led to a notable increase in PTSD symptoms, particularly avoidance.

Furthermore, refugees diagnosed with PTSD often also received diagnoses of secondary psychotic features. One study found that 74 out of 181 refugees (41%) with PTSD also had secondary psychotic features. These features included hallucinations and delusions, and their impact can make PTSD with Secondary Psychotic features (PTSD-SP) a very challenging disorder. Refugees are especially vulnerable to developing these secondary psychotic features with PTSD because they typically experience more long-term trauma than other PTSD patients. Additionally, refugee populations often lack familiar support systems when they seek asylum in new countries to escape dangerous situations, which makes the problem worse.

Prior to Migration

Before migration, environmental factors can contribute to the development of mental disorders. Among Ethiopian immigrants and refugees, rates of depression were significantly higher in individuals who had experienced trauma before migrating and had also been held in a refugee camp. Other factors linked to depression included witnessing death in the family and not having basic resources like water, shelter, and food. Individuals who experienced more traumatic events were more vulnerable to depression, as trauma can lead to feelings of hopelessness and a loss of interest in activities. In North Korea, war and organized violence are not the main reasons people seek asylum; instead, they often try to escape political oppression. Nevertheless, traumatic experiences such as torture, violence, imprisonment, and witnessing death are common.

In a group of North Korean refugees, insomnia, which is often linked to symptoms of depression and post-traumatic stress, was higher in those who had experienced traumatic events before migrating. These findings suggest that the development of insomnia in refugees could be connected to these traumatic experiences. A study of Syrian refugees in Turkey found that other factors could contribute to developing PTSD, such as having a previous psychiatric diagnosis or a family history of mental illness, in addition to experiencing trauma. Refugees face significant challenges in accessing healthcare, alongside trauma and prior diagnoses, when they are in war zones or areas affected by natural disasters.

During Migration

During migration, other stressors can be linked to depression and anxiety. Stress can come from an uncertain future, which is common for asylum seekers. In two Danish asylum centers, the mental health of Iraqi asylum seekers whose applications were denied was assessed. In this group, 94% showed symptoms of anxiety, and 100% showed symptoms of depression. The length of time spent in the asylum centers and the number of traumatic events experienced were considered risk factors for psychological distress.

Among those in refugee camps, daily stressors can worsen mental health problems. These stressors include not having basic necessities, restricted movement, and ongoing worries about safety, as refugee camps are only meant to be short-term solutions. Consistency in the lives of refugees can help reduce mental distress. For example, the rate of PTSD was lower than expected in a group of Syrian child refugees, possibly because these children traveled with at least one parent, which provided a crucial part of the child's familiar social environment. Therefore, having a parent accompany children during migration could be a protective factor that reduces post-traumatic stress rates among some children. Additionally, a successful journey during migration was associated with creating feelings of hope for the future. However, a parent's anxiety can also affect a child's anxiety, so a parent's presence may not always be beneficial, especially if the parents are experiencing mental distress themselves.

Post-Migration

Often, depression among refugees has lasting effects. A study of Guatemalan refugees in Mexico found that 38.8% experienced depression at some point in their lives. Karenina refugees settled on the Thai-Burma border had a lifetime prevalence of depression of 41.8%. Stress after migration can be related to feelings of insecurity. A group of North Korean refugees settled in South Korea felt unsafe due to a fear of being arrested and sent back to North Korea. Mental distress after migration has also been linked to acculturative stress. Refugees were about ten times more likely to have PTSD than the general population of their host country, showing that mental distress in refugee populations does not disappear after resettlement. These PTSD rates were observed among 7,000 refugees resettled in Western countries. Comparing refugees only with the general population might not provide a complete picture, so future studies need to compare refugee rates with other groups, such as veterans or victims of domestic violence.

Acculturation is the process of integrating into a new culture while keeping one's original culture and identity. This process can create significant stress for new refugees trying to rebuild their lives in new countries, often leading to anxiety and depression, and worsening existing post-traumatic stress. Acculturative stress arises from the demands of the immigration experience. It is linked to experiences that cause stress among immigrants and refugees. These include not being familiar with daily tasks, difficulty finding employment, learning the host country's language, discrimination, and feeling like they do not belong in their new environment. For example, Bosnian refugees living in Australia reported significantly more stress in adapting to the host language than Bosnian refugees living in Austria. Acculturative stress affects mental health based on the social environment a refugee experiences in a host country, influenced by immigration policies and the general attitude of the host society towards refugees and different cultures.

Discussion and Conclusion

Refugee populations are more likely to experience post-traumatic stress disorder, depression, and anxiety because they are exposed to traumatic events before migrating. Before the migration process, refugees often endure trauma from organized violence and political oppression, which can involve the death of a loved one, torture, imprisonment, witnessing public executions, and lacking basic necessities. Other risk factors before migration include having previous diagnoses of psychiatric disorders oneself or within the family. These disorders can develop at any age, though some age groups might experience more severe symptoms than others. Children, in particular, can develop behavioral and emotional problems from specific traumatic experiences, such as forced migration. However, adolescents were more likely to have PTSD, which could be linked to factors like having more siblings or older parents.

Studies have shown mixed results regarding differences in mental distress between males and females. However, one study indicated that being female was a risk factor for depression, with females being more likely than males to have a diagnosed mental health condition. In terms of PTSD, women were more likely to show symptoms, though this finding has not been consistent among some Syrian Kurdish refugees, possibly due to cultural differences. Nevertheless, being female was generally linked to a higher prevalence of mental distress.

During migration, several factors contributed to mental distress, such as ongoing feelings of unsafety and an uncertain future. Rates of depression and anxiety were high among refugee populations whose asylum requests were denied. A protective factor for children during migration is maintaining some aspects of their previous environment, such as ensuring a child travels with at least one parent.

After migration, many difficulties can cause mental distress to worsen or lead to long-term mental health symptoms. A common factor linked to mental distress after migration is acculturative stress, often experienced by refugees and immigrants. Experiences that result in acculturative stress include not being familiar with daily tasks, overcoming language barriers, and facing discrimination. Acculturative stress is often unique to one's environment because of the host country's attitudes and the extent of changes needed to adapt, such as language. Not only are refugee populations vulnerable to PTSD, but they also often experience secondary features with their PTSD, which increases the burden of the disorder. These features can include hallucinations and delusions. Refugees are uniquely vulnerable to these secondary features because they often experience more long-term trauma. They are placed into unfamiliar environments and lack familiar support systems. Consequently, refugees with PTSD are likely to also experience secondary psychotic symptoms.

This review highlighted the higher rates of mental health disorders, especially depression, anxiety, and PTSD, among refugees who have experienced trauma and forced migration. It emphasized the importance of managing these mental health challenges with great empathy and a higher level of care. Possible ways to help include involving family members in their care, providing language interpreters, being patient, and creating an inclusive environment that considers the psychological, social, and cultural aspects of refugee lives. Comparing refugees only with the general population might not show the full picture. Therefore, more studies are needed to compare refugee mental health rates with other groups, such as veterans, victims of domestic violence, or other victims of violence, in future research.

There are few studies available on mental health issues in refugee populations, possibly due to a lack of funding in this area. Additionally, few studies have mentioned potential errors in data reporting due to refugees' inability to accurately describe their symptoms when experiencing moderate to severe mental distress. More research is needed to examine the increased vulnerability of refugee populations to mental health disorders and to develop management guidelines to better integrate them into new host societies.

Summary

Many people around the world have to leave their homes because of war or danger. There are more than 19 million such people. These people often have more mental health problems than others. They might feel worried, very sad, or have bad memories from their past.

These problems can start before they leave their home, like from seeing war or bad things happen. They can also happen after they move, such as feeling lonely or trying to fit into a new country. These problems can last a long time, even after they have found a new home.

For example, in one group of people called Karenni refugees, about 4 out of 10 had problems with sadness or worry. This is much higher than in the US, where about 1 out of 10 people have these feelings. These problems came from bad events like violence, being bothered, or not having basic needs like food or shelter.

People who have to leave their homes often face different kinds of stress than other groups who have been through bad things. This is because they have unique experiences and also have to learn a whole new way of life. This includes new places, new rules, and not having their usual friends or family around. Also, not being able to find work or learn the new language can make these feelings worse.

Some signs of sadness include changes in eating or sleeping, feeling sad most of the time, losing interest in fun things, having low energy, feeling worthless or guilty, having trouble focusing, or thinking about dying. Signs of bad memories (PTSD) include having flashbacks, avoiding certain things, or being easily scared. Signs of being worried (anxiety) include feeling restless, easily annoyed, tired, worrying too much, having trouble relaxing, sleeping, or focusing.

There are many different types of people who have to leave their homes. Lately, more people from Arabic-speaking countries have been moving to places like Europe. Even though more Arabic-speaking people are moving, there are not many recent studies about their mental health. It is hard to compare studies because they often use different ways to measure mental health.

Another thing that can cause mental health problems is the stress of adapting to a new culture. This happens when people try to fit into a new way of life while still holding on to their own culture. This process depends on how both the new person and the people in the new country act. This stress is known to be a risk factor for mental health problems.

This information was put together to understand why people who have to leave their homes are more likely to have problems like bad memories, sadness, and worry. It also looked at what happens before, during, and after they move that can make these problems worse.

Refugee Health

One study looked at Yazidi children and teenagers who had to leave their homes. It found that teenagers had more mental health problems than younger children. Teenagers might have more stress because they often had more brothers and sisters. Other things that made sadness more likely included having older parents, being a girl, and seeing someone get hurt or die. Girls were more likely to be diagnosed with a mental health problem than boys.

Another study looked at Yazidi children and teenagers right after they had to leave their homes. It found that these children had more behavior and emotional problems than children who had not been through such bad experiences. After moving, these children were very shy and avoided other children. They also said they were afraid of being captured and did not feel safe. Most also had trouble sleeping. More than one-third of these children were diagnosed with sadness.

Bad events like torture can lead to mental health problems. People in war zones often go through at least one bad event, and many are tortured. For example, among Syrian Kurdish people, there was a link between having bad memories and going through things like having to run away, seeing violence, or being held captive. More men had experienced bad events, but more women had symptoms of bad memories. However, in one area, there was no difference in bad memories between men and women, which might be because of different cultures.

People who have bad memories can get worse if another stressful event happens. A study looked at people from Iran, the Balkan region, and Turkey who already had bad memories. When these people went through another big life event, they tried harder to avoid things. This might be their way of trying not to feel the pain of past bad events again. Overall, new big life events made symptoms of bad memories much worse, especially the avoidance behavior.

Also, people with bad memories often have other mental health problems like seeing or hearing things that are not there, or believing things that are not true. One study found that 4 out of 10 people with bad memories had these extra problems. These extra problems can make the bad memories even harder to deal with. People who have to leave their homes are more likely to have these extra problems because they often go through bad events for a very long time. They also often do not have their usual support from family and friends when they are trying to find a new home, which makes the problem worse.

Prior to Migration

Before people move, things in their environment can lead to mental health problems. For example, people from Ethiopia had higher rates of sadness if they went through bad events before moving or if they stayed in a refugee camp. Other things like seeing a family member die or not having enough water, shelter, or food were also linked to sadness. The more bad events someone went through, the more likely they were to feel sad. This is because bad events can make people feel hopeless and lose interest in things. In North Korea, people often leave not because of war, but to escape unfair treatment. However, they still go through bad things like torture, violence, being put in prison, and seeing people die.

In one group of North Korean people who had to leave their homes, those who went through bad events before moving had more trouble sleeping. Trouble sleeping is often linked to feelings of sadness and bad memories. This suggests that these bad experiences might cause sleeping problems. A study of Syrian people in Turkey found that other things could also lead to bad memories, like having a mental health problem in the past or having family members with mental health problems, along with going through bad events. People in war zones or places hit by natural disasters also face big problems getting health care, on top of the bad events and past diagnoses.

During Migration

While people are moving, other stressful things can cause sadness and worry. Feeling unsure about the future, which is common for people seeking a new home, can be a big stressor. In two places in Denmark that housed people seeking new homes, almost all of the Iraqi people who were told they could not stay felt worried (94%) or sad (100%). How long they stayed in these centers and how many bad events they went through seemed to make these mental health problems worse.

For people living in refugee camps, everyday stressors can make mental problems worse. These include not having basic things they need, not being able to move freely, and always worrying about their safety, as camps are only meant for a short time. Having some stability in their lives can help ease mental distress. For example, one group of Syrian children who had to leave their homes had fewer bad memories than expected. This might be because these children traveled with at least one parent, which kept a key part of their social life the same. So, having a parent with them during the journey might protect children from developing bad memories. Also, a successful journey can make people feel hopeful about the future. However, if a parent is worried, this can also make a child worried, so having a parent there is not always helpful, especially if the parents are struggling with their own mental health.

Post-Migration

Often, sadness in people who have to leave their homes can last a long time. One study of people from Guatemala in Mexico found that almost 4 out of 10 had experienced sadness at some point in their lives. Karenina people living near the Thai-Burma border had similar rates of sadness (about 4 out of 10). Stress after moving can come from feeling unsafe. A group of North Korean people who moved to South Korea felt unsafe because they feared being arrested and sent back to North Korea. Mental distress after moving has also been linked to the stress of fitting into a new culture. People who had to leave their homes were about ten times more likely to have bad memories than the general population in the countries they moved to. This shows that mental distress does not go away after they find a new home. These numbers were from 7,000 people who moved to Western countries. Comparing these people only to the general population might not tell the whole story; future studies should also compare them to other groups like soldiers or victims of violence.

Fitting into a new culture means learning a new way of life while still keeping your own culture and identity. This process can cause a lot of stress for people trying to start over in new countries, often leading to worry and sadness, and making bad memories even worse. This type of stress comes from the demands of moving. It is linked to things that cause stress for new people, such as not knowing how to do everyday tasks, having trouble finding a job, learning a new language, being treated unfairly, and feeling like they do not belong in their new home. For example, people from Bosnia living in Australia reported much more stress about learning the new language than those living in Austria. The stress of fitting in affects mental health based on how friendly and accepting the new country is towards people from other cultures and how big the changes are, like learning a new language.

Discussion and Conclusion

People who have to leave their homes are more likely to have bad memories, sadness, and worry because they often go through bad experiences before they move. Before moving, they might face trauma from violence or unfair treatment, such as a loved one dying, torture, being put in prison, seeing public executions, and not having basic needs. Other risks before moving include having mental health problems themselves or in their family in the past. These problems can happen at any age, but some age groups might have stronger symptoms. Children, in particular, can develop behavior and emotional problems from bad experiences like having to leave their home. However, teenagers were more likely to have bad memories, which could be linked to things like having more brothers and sisters or older parents.

Studies showed different results about whether men or women had more mental distress. However, one study showed that being a female was a risk for sadness. Women were more likely than men to be diagnosed with a mental health problem. When it came to bad memories, women were more likely to show symptoms. But this was not always true for some Syrian Kurdish people, possibly due to cultural differences. Still, being a woman was generally linked to more mental distress.

While people were moving, several things caused mental distress, like still feeling unsafe and unsure about the future. Many people who were told they could not stay in their new country had high rates of sadness and worry. One thing that helps children when moving is keeping some parts of their old life the same, like making sure the child travels with at least one parent.

After moving, many difficulties can make mental distress worse or cause mental health problems to last a long time. A common cause of mental distress after moving is the stress of fitting into a new culture, which many people who move experience. Things that cause this stress include not knowing how to do daily tasks, having trouble with a new language, and facing unfair treatment. This stress is often different for each person because of how the new country treats people from other cultures and how big the changes are, like language. Not only are people who move more likely to have bad memories, but they also often have other problems with their bad memories, which makes it even harder. These problems can include seeing or hearing things that are not there. People who move are more likely to have these extra problems because they often go through bad events for a longer time. They are put into new places and do not have their usual support from family and friends. Because of this, people who have bad memories and have moved are likely to experience these extra mental health problems.

This article showed that people who have gone through trauma and had to leave their homes have higher rates of mental health problems like bad memories, sadness, and worry. It stressed how important it is to treat these mental health problems with great kindness and high-quality care. Ways to help could include involving family in their care, using language helpers, being patient with them, and creating a welcoming place that understands their culture and social life. Comparing these people only to the general population might not tell the whole story. So, more studies are needed to compare their mental health rates to other groups like soldiers, victims of violence, or others who have experienced trauma.

There are not many studies about mental health problems in people who have moved, possibly because there is not enough money for this kind of research. Also, few studies have talked about possible mistakes in the information because people might not be able to report their symptoms accurately when they are feeling very distressed. More studies are needed to understand why people who move are more likely to have mental health problems and how to help them fit better into a new country.
