Factores asociados a malestar psicológico o trastornos mentales comunes en poblaciones migrantes a lo largo del mundo / Factors associated with psychological distress or common mental disorders in migrant populations across the world

Se revisan sistemáticamente los factores asociados a la presencia de malestar psicológico o trastornos mentales comunes en poblaciones migrantes. Se revisaron los artículos publicados entre enero de 2000 y diciembre de 2014, de los que se seleccionaron 85 que aplicaban análisis estadísticos multivariantes. Los trastornos mentales comunes se asociaban significativamente a características sociodemográficas y psicológicas, lo mismo que se observa en grandes estudios epidemiológicos de poblaciones generales. La probabilidad de trastornos mentales comunes aumentó significativamente entre grupos de migrantes, además de por la región de origen, por los siguientes factores: sucesos traumáticos previos; migración forzosa, escasamente planificada o ilegal; bajo nivel de aculturación, vivir solo o separado de la familia en el nuevo país, falta de apoyo social, discriminación percibida y tiempo transcurrido en el nuevo país. Para diseñar estrategias preventivas se ha de tener en cuenta los factores asociados al riesgo de morbilidad psiquiátrica en poblaciones migrantes (AU)

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 (AU)

World region of origin and common mental disorders among migrant women in Spain.

Migration can affect the mental health of migrants. This cross-sectional study has two objectives: (1) to compare the prevalence of common mental disorder (CMD) between migrants (n = 458) living in Granada (Spain) and Spanish-born women (n = 448); (2) within migrants, to analyse the associations of world region of origin, other sociodemographic factors and post-migration features with the presence of CMD. Participants answered a questionnaire, including sociodemographic characteristics, post-migration features and CMD that was measured by Kessler K6-scale. Logistic regression analyses showed that CMD (K6 ≥ 13) was significantly higher among migrants than Spaniards. Compared with Spaniards, the odds of CMD were 3.6 [95 % confidence intervals (CI) 2.1­6.0] and 2.9 (CI 1.6­5.3), respectively, for Latin Americans and for Moroccan and other African women. Among migrants, Latin Americans as opposed to the reference group (migrants from other countries), had higher probability of CMD (OR 2.3, CI 1.1­4.9). This study supports the hypothesis that migration leads to mental distress. Consideration of world region of origin may clarify the differences observed in mental health across different migrant groups.
