Epidemiology of psychiatric morbidity among migrants compared to native born population in Spain: a controlled study

Cross-Cultural Validation of the Barcelona Immigration Stress Scale

The concept of acculturative stress has been the subject of debate, resulting in contradictory arguments regarding its measurement. Many of the existing acculturative stress instruments have been developed for use with specific migrant groups. The objective of the current study is to revisit the psychometric properties of the Barcelona Immigration Stress Scale, an instrument aimed at measuring stress levels associated with the migration trajectory in any migrant group. Using a sample of 915 migrants who consulted in primary care, we carried out principal component and confirmatory factor analyses as well as item response theory analyses applied both to the entire sample and to different migratory groups separately. The new reduced version of the scale has very good psychometric properties both in general and applied to the Latino migratory group, the largest in the area where the study was carried out. Results were acceptable among sub-Saharan, North African, and Asian groups but not among Eastern Europeans. These results are discussed through the specificities of each migratory group and the limitations of psychometrics to capture the complexity of immigration-related and acculturative stress.

Global prevalence of anxiety and PTSD in immigrants: a systematic review and meta-analysis

BACKGROUND

A systematic and meta-analysis of the prevalence of anxiety and posttraumatic stress disorder (PTSD) in immigrants was conducted.

METHODS

Based on the keywords, scientific databases were systematically searched to identify articles. The search included the three databases PubMed, Google Scholar and Research Gate until June 2020. The analysis was performed to assess the prevalence of anxiety and PTSD; subgroups were examined based on anxiety disorders.

RESULTS

The prevalence of agoraphobia, PTSD, generalized anxiety disorder (GAD), panic disorder, obsessive-compulsive disorder (OCD), social phobia and specific phobia were 4, 25, 9, 4, 3, 5 and 8%, respectively.

CONCLUSIONS

Considering the findings of the present study regarding the significant prevalence of anxiety and PTSD in the immigrant population, it is necessary to pay special attention to the mental health of this population.

Epidemiology of depression among displaced people: A systematic review and meta-analysis

INTRODUCTION

Displaced people are prone to develop mental health problems due to resettlement in new environments, traumatic events and forced migration. Depression is a mental health problem repeatedly observed among displaced people such as refugees, migrants, asylum seekers and internally displaced persons (IDPs). Therefore, estimating the global pooled prevalence of depression as well as pinpointing its determinants may support policymakers and health care workers to mitigate the disease burden and improve the psychological well-being of displaced people.

METHODS

PubMed, EMBASE, CINAHIL, Psych-INFO, and SCOPUS databases were searched for English written relevant observational studies conducted between 1984 and 2020. The methodological quality of studies was assessed using the Newcastle Ottawa Scale (NOS). Heterogeneity across studies was checked using the Q- and I² test. Publication bias was checked by observing Funnel plot symmetry and using Egger's regression test. STATA 16 was used to combine studies using a random effect model.

RESULTS

Of the 4102 studies identified, 81 studies with an overall sample size of 53,458 were included in the current systematic review and meta-analysis. The pooled prevalence estimate of depression among displaced people was 26.4% (95% CI; 22.2-31.1). Also, three in five IDPs, one in three refugees and asylum seekers and one in four migrants suffer from depression globally. Being female migrant [AOR: 2.46 95% CI: 1.79-3.13, I²=34.5%), non-partnered marital status [AOR: 2.29, 95% CI: 1.29-3.30, I²= 0.00%], and perceived low social support [AOR: 1.76, 95% CI: 1.00-2.52, I²=34.6%] were significant determinants of depression among displaced people.

CONCLUSION

Overall, around 1 in 4 displaced people suffer from depression and exceed the prevalence of depression reported by community samples in different nations and demonstrate a need for culturally fitting and targeted responses from migrant/refugee host nations and their serving clinicians.

Higher prevalence of depressed mood in immigrants' offspring reflects their social conditions in the host country: The HELIUS study

BACKGROUND

Immigrants from low- and middle-income countries who have settled in high-income countries show higher risks of depression in comparison with host populations. The risks are associated with adverse social conditions. Indecisive results have been reported on the depression risks of the offspring of immigrant populations.

OBJECTIVE

To assess the prevalence of depressed mood in immigrant offspring relative to the host population and to analyse whether that risk is explained by social conditions.

METHODS

Cross-sectional data from the Dutch HELIUS study were analysed, involving 19,904 men and women of Dutch, South-Asian Surinamese, African Surinamese, Turkish or Moroccan ethnic descent aged 18 to 70. Depressive symptomatology was assessed using the Patient Health Questionnaire-9 (PHQ-9). Indicators of social conditions were socioeconomic position (educational level, occupational level, employment status), perceived ethnic discrimination and sociocultural integration (ethnic identity, cultural orientation, social network). We used logistic regression to assess the risk of depressed mood (PHQ-9 sum score ≥10) in immigrants' offspring, as well as in first generation immigrants, relative to the risk in the host population. Social indicators were stepwise added to the model.

RESULTS

The prevalence of depressed mood was 13% to 20% among immigrant offspring, with the lowest level for those of African Surinamese descent; prevalence in the Dutch origin population was 7%. Relative risk of depressed mood, expressed as average marginal effects (AMEs), decreased substantially in all offspring groups after adjustment for socioeconomic indicators and discrimination. E.g. the AME of Turkish vs. Dutch decreased from 0.11 (0.08-0.13) to 0.05 (0.03-0.08). Patterns resembled those in first generation immigrants.

CONCLUSIONS

Results suggest that the observed higher prevalence of depressed mood in immigrants' offspring will decline to the level of the host population as the various populations grow closer in terms of socioeconomic position and as immigrant offspring cease to experience discrimination.

Psychosocial Working Conditions and Well-Being of Migrant Workers in Spain

This study examines the relationship beween employment and psychosocial working conditions and well-being of native and migrant workers in the working population of Spain. Data from the 7th Spanish Survey of Working Conditions was used to conduct a confirmatory factor analysis (n = 8508) to identify the main latent variables that influenced well-being. Using structural equation modeling and multivariate analysis, we found different patterns and perceptions of well-being and working conditions in these two groups. We discuss the reasons for these differences and suggest directions for further research in this area.

Depression in migrant workers and nationals of Qatar: An exploratory cross-cultural study

BACKGROUND

The aim of this study was to compare the prevalence of depressive symptoms among migrants and non-migrants living in Qatar and identify variables associated with depressive symptomology in these groups, including culture of origin, time living in country and perceived quality of life. In addition, we tested if the latter two variables moderated the effect of culture of origin on depressive symptomology in the migrant groups.

SUBJECT AND METHODS

A telephone survey of a probability-based sample of 2,520 participants was conducted in February 2016. The sample was divided into three groups based on nationality and income: labour migrants (LMs), white-collar migrants (WCMs) and non-migrants or Qatari nationals (QNs). Participants completed the Whooley two-question test for depression.

RESULTS

The odds of depression were significantly increased in LMs (OR = 3.31, 95% CI = 2.36-4.65) and WCMs (OR = 1.40, 95% CI = 1.04-1.90) compared with non-migrants. Among LMs, having a problem with current employer in the last 3 months was also associated with depressive symptoms (OR = 2.10, 95% CI = 1.14-3.84). Culture of origin was significantly associated with depressive symptoms including South Asians (OR = 3.12, p < .001), East Asians (OR = 0.52, p = .013) and Westerners (OR = 0.45, p = .044) relative to Arabs. LM status remained strongly associated with depressive symptoms independent of culture of origin (OR = 2.02, p < .001).

CONCLUSION

Perceived quality of life, but not length of stay, appears to be an important variable in explaining differences in symptoms between some cultural groups. Findings from this study highlight the importance of the context of migration and culture of origin as potential determinants of depressive symptomology in the host country.

Prevalence of Depression among Migrants: A Systematic Review and Meta-Analysis

As the number of migrants worldwide increases, it is worthwhile to examine the extent to which depression has affected this group of often vulnerable individuals. The purpose of this systematic review and meta-analysis is to examine the aggregate prevalence of depression among international migrants and to explore the variations in prevalence with demographic and educational factors. A search was conducted on the online databases PubMed and ScienceDirect whole using the terms "depression", "depressive disorder", "immigration", "immigrant", "migration", and "migrant". A total of 25 studies met our inclusion criteria. A random-effects model meta-analysis calculated an aggregate prevalence of 15.6% among migrants. Heterogeneity was identified by meta-regression and subgroup analyses, and the level of educational attainment, employment status, and length of residency spent in country of migration were found to be significant moderators contributing to depression prevalence. In conclusion, newly arrived migrants appear to be susceptible to developing depression and it is imperative that more in the form of preventive strategies and increased assistance be incorporated to ensure their psychological wellbeing and improve their mental health outcomes. Further research should be conducted to better understand the risk of psychiatric disorders among members of this subpopulation.

Incidence and prevalence of mental disorders among immigrants and native Finns: a register-based study

PURPOSE

Migrants appear to have a higher risk of mental disorders, but findings vary across country settings and migrant groups. We aimed to assess incidence and prevalence of mental disorders among immigrants and Finnish-born controls in a register-based cohort study.

METHODS

A register-based cohort study of 184.806 immigrants and 185.184 Finnish-born controls (1.412.117 person-years) was conducted. Information on mental disorders according to ICD-10 was retrieved from the Hospital Discharge Register, which covers all public health care use.

RESULTS

The incidence of any mental disorder was lower among male (adjusted HR 0.82, 95% CI 0.77-0.87) and female (aHR 0.76, 95% CI 0.72-0.81) immigrants, being lowest among Asian and highest among North African and Middle Eastern immigrants. The incidence of bipolar, depressive and alcohol use disorders was lower among immigrants. Incidence of psychotic disorders was lower among female and not higher among male immigrants, compared with native Finns. Incidence of PTSD was higher among male immigrants (aHR 4.88, 95% CI 3.38-7.05).

CONCLUSIONS

The risk of mental disorders varies significantly across migrant groups and disorders and is generally lower among immigrants than native Finns.

Mental Health in Immigrants Versus Native Population: A Systematic Review of the Literature

The relationship between psychopathology and migration presents unresolved questions.

OBJECTIVES

To determine whether there is a higher incidence of mental illness among immigrants, to describe the nosologic differences between immigrant and native populations, and to identify the risk factors involved of immigration.

METHODS

A systematic review was conducted using the PubMed, Science Direct, ISI, Scopus, Psycinfo, Cochrane, and Cuiden databases. The search strategy was conducted using the MeSH thesaurus for the controlled terms "mental disorders," "mental health," "transients and migrants," "immigrants," and "epidemiology." The quality of the articles was analyzed by using the Equator Guidelines, following checklists according to the methodological design of the studies by two independent reviewers.

RESULTS

From a total of 817 studies found, 21 met the inclusion criteria. Out of the 21 studies selected, 13 showed a higher prevalence of mental illness.

CONCLUSIONS

Migration represents a major challenge, but it does not lead exclusively to mental distress. Immigrants experience more problems in depression, anxiety, and somatic disorders, pathologies related directly to the migration process and stress suffered. Resources should be oriented to primary and community care.

The generational gap: Mental disorder prevalence and disability amongst first and second generation immigrants in Australia

Despite unprecedented numbers of migrants internationally, little is known about the mental health needs of immigrant groups residing in common countries of resettlement. The majority of studies support the 'healthy migrant hypothesis', but few studies have examined: 1) shifts in prevalence patterns across generations; 2) how prevalence relates to disability in immigrant groups. Our study examined the prevalence of common mental disorders and disability in first and second generation migrants to Australia. Twelve-month and lifetime prevalence rates of affective, anxiety, and substance use disorders were obtained from the Australian National Survey of Mental Health and Wellbeing (N = 8841). First generation immigrants (born overseas) and second generation immigrants (both parents overseas) from non-English and English speaking backgrounds were compared to an Australian-born cohort. Disability was indexed by days out of role and the WHO Disability Assessment Schedule (WHODAS12). First generation immigrants with non-English speaking (1G-NE) backgrounds evidenced reduced prevalence of common mental disorders relative to the Australian-born population (adjusted odds ratio 0.5 [95% CI 0.38-0.66]). This lower prevalence was not observed in second generation immigrant cohorts. While overall levels of disability were equal between all groups (p > 0.05), mental health-related disability was elevated in the 1G-NE group relative to the Australian-born group (p = 0.012). The findings challenge the overarching notion of the "healthy migrant" and suggest a dissociation between reduced prevalence and elevated mental health-related disability amongst first generation immigrants with non-English speaking backgrounds. These findings highlight the heterogeneous psychiatric needs of first and second generation immigrants.

Factors associated with psychological distress or common mental disorders in migrant populations across the world

We systematically review factors associated with the presence of psychological distress or common mental disorders in migrant populations. Articles published between January 2000 and December 2014 were reviewed and 85 applying multivariate statistical analysis were selected. Common mental disorders were significantly associated with socio-demographic and psychological characteristics, as observed in large epidemiological studies on general populations. The probability of common mental disorders occurrence differs significantly among migrant groups according to their region of origin. Moreover, traumatic events prior to migration, forced, unplanned, poorly planned or illegal migration, low level of acculturation, living alone or separated from family in the host country, lack of social support, perceived discrimination, and the length of migrants' residence in the host country all increase the likelihood of CMD. In contrast, language proficiency, family reunification, and perceived social support reduce such probability. Factors related with the risk of psychiatric morbidity among migrants should be taken into account to design preventive strategies.

Patterns of pharmaceutical use for immigrants to Spain and Norway: a comparative study of prescription databases in two European countries

BACKGROUND

Although equity in health care is theoretically a cornerstone in Western societies, several studies show that services do not always provide equitable care for immigrants. Differences in pharmaceutical consumption between immigrants and natives are explained by variances in predisposing factors, enabling factors and needs across populations, and can be used as a proxy of disparities in health care use. By comparing the relative differences in pharmacological use between natives and immigrants from the same four countries of origin living in Spain and Norway respectively, this article presents a new approach to the study of inequity in health care.

METHODS

All purchased drug prescriptions classified according to the Anatomical Therapeutic Chemical (ATC) system in Aragon (Spain) and Norway for a total of 5 million natives and nearly 100,000 immigrants for one calendar year were included in this cross-sectional study. Age and gender adjusted relative purchase rates for immigrants from Poland, China, Colombia and Morocco compared to native populations in each of the host countries were calculated. Direct standardisation was performed based on the 2009 population structure of the OECD countries.

RESULTS

Overall, a significantly lower proportion of immigrants in Aragon (Spain) and Norway purchased pharmacological drugs compared to natives. Patterns of use across the different immigrant groups were consistent in both host countries, despite potential disparities between the Spanish and Norwegian health care systems. Immigrants from Morocco showed the highest drug use rates in relation to natives, especially for antidepressants, "pain killers" and drugs for peptic ulcer. Immigrants from China and Poland showed the lowest use rates, while Colombians where more similar to host countries.

CONCLUSIONS

The similarities found between the two European countries in relation to immigrants' pharmaceutical use disregarding their host country emphasises the need to consider specific immigrant-related features when planning and providing healthcare services to this part of the population. These results somehow remove the focus on inequity as the main reason to explain differences in purchase between immigrants and natives.

Hispano-Americans in Europe: what do we know about their health status and determinants? A scoping review

Background

Policy makers and health practitioners are in need of guidance to respond to the growing geographic mobility of Hispano-American migrants in Europe. Drawing from contributions from epidemiology, social sciences, demography, psychology, psychiatry and economy, this scoping review provides an up-to-date and comprehensive synthesis of studies addressing the health status and determinants of this population. We describe major research gaps and suggest specific avenues of further inquiry.

Methods

We identified systematically papers that addressed the concepts “health” and “Hispano Americans” indexed in five data bases from Jan 1990 to May 2014 with no language restrictions. We screened the 4,464 citations retrieved against exclusion criteria and classified 193 selected references in 12 thematic folders with the aid of the reference management software ENDNOTE X6. After reviewing the full text of all papers we extracted relevant data systematically into a table template to facilitate the synthesising process.

Results

Most studies focused on a particular disease, leaving unexplored the interlinkages between different health conditions and how these relate to legislative, health services, environmental, occupational, and other health determinants. We elucidated some consistent results but there were many heterogeneous findings and several popular beliefs were not fully supported by empirical evidence. Few studies adopted a trans-national perspective and many consisted of cross-sectional descriptions that considered “Hispano-Americans” as a homogeneous category, limiting our analysis. Our results are also constrained by the availability and varying quality of studies reviewed.

Conclusions

Burgeoning research has produced some consistent findings but there are huge gaps in knowledge. To prevent unhelpful generalisations we need a more holistic and nuanced understanding of how mobility, ethnicity, income, gender, legislative status, employment status, working conditions, neighbourhood characteristics and social status intersect with demographic variables and policy contexts to influence the health of the diverse Hispano-American populations present in Europe.

Psychiatric morbidity and predisposing factors in a primary care population in Madrid

OBJECTIVES

The aim of this article is to estimate the prevalence of mental disorders in patients in primary care centers in an urban area of Madrid and to study possible associated risk factors.

METHODS

Cross-sectional month prevalence was evaluated in two phases in an urban area of Madrid. The sample for the first phase included 635 individuals (aged 18-65 years), and the second phase included 320 individuals. Socio-demographic variables (age, sex, educational level, living conditions and country of origin) and clinical variables (psychiatric diagnosis and level of psychosocial stress) were studied. The instruments used for screening were the General Health Questionnaire (GHQ)-28 item questionnaire and the MULTICAGE-CAD 4test. The Mini International Neuropsychiatric Interview (M.I.N.I.) was used in the second phase (in 'possible cases' and 20% of the 'non-cases'). Prevalence was calculated using weighted logistic regression with the observed sampling fractions of the patients in study phase 2 as sample weights.

RESULTS AND CONCLUSIONS

The month prevalence of mental disorders was 31.3% (95% confidence interval (CI) = [27.6, 35.2]). Anxiety disorders were the most frequent diagnoses with a prevalence of 22.4% (95% CI = [17.8, 27.1]), followed by depressive disorders (16.6%; 95% CI = [12.9, 20.3]), substance abuse or dependence disorders (5.6%; 95% CI = [3.2, 6.9]) and posttraumatic stress disorder (PTSD; 4.4%; 95% CI = [2.0, 2.8]). Factors associated with mental disorders were the presence of stressful life events in the previous 12 months, Latin American region of origin, being woman aged 25 and 34 years and having a low education level.

Comparative epidemiologic study of skin diseases in foreign children and children of Spanish origin in Alicante, Spain

INTRODUCTION

Previous studies in Spain have shown that the foreign and immigrant populations can have different diseases to Spanish-born individuals. However, no comparative study has specifically investigated foreign children in Spain.

MATERIAL AND METHODS

The objective of the study was to compare skin diseases in foreign children with those in children born in Spain of Spanish parents. We included all patients under 15 years of age who were seen in our dermatology department between January 2007 and December 2007.

RESULTS

During the study period, 3108 pediatric patients were seen in the dermatology department. Of these, 2661 (85.6%) were Spanish and 447 (14.3%) were foreigners. Foreign children sought medical care more often (11.4%) than Spanish children (6%) (P<.001) and made less use of the specialist outpatient clinic (59.6% vs 68.8% [P<.001]) and more use of emergency care. Complaints observed more frequently in the foreign children were scabies (adjusted odds ratio [aOR], 10.6; 95% CI, 4.71-24.10), arthropod bites (aOR, 2.80; 95% CI, 1.14-6.87), hypopigmentation (aOR, 2.61; 95% CI, 1.06-6.44), and atopic dermatitis (aOR, 1.65; 95% CI, 1.19-2.31). Melanocytic nevus was observed more frequently in Spanish children (aOR, .50; 95% CI, .30-.83).

CONCLUSIONS

Differences between children born in Spain of Spanish parents and foreign children were found for type of visit and frequency of skin diseases.
