Migration and depression: A cross-national comparison of Mexicans in sending communities and Durham, NC.

Rationale: Latino immigrants have been shown to average better health and longevity than native whites, in spite of their relative socioeconomic disadvantage. However, mental health outcomes stand in stark contrast to this epidemiological "paradox," as factors such as depression are significantly higher for Latino immigrants than other groups.

Objective: We explore the link between migration and depressive feelings using a binational random survey of Mexicans in Durham, NC and sending communities in Mexico.

Method: Explanations for the link between migration and depression, such as acculturative stress, lack of social support, and powerlessness and isolation, are analyzed by comparing results for protective vs. risk factors between residents of Mexico and Durham, and among immigrants themselves. Besides, selection hypothesis is explored using propensity matching scores.

Results: Results show little support for selection as an important source of migrant depression, and instead provide strong evidence that migration itself, and the disruption of social networks that it entails, is primarily responsible for the association. Family separation, in particular, is the strongest predictor of depressive feelings and accounts for a sizeable portion of the heightened depression among migrants.

Conclusions: Understanding the subjective experiences of migration is necessary to better integrate newcomers into host societies.
