The mental health-migration interface among sub-Saharan African and Chinese populations.

This paper describes the burden of mental disorders among sub-Saharan African and Chinese populations. Data on mental disorders in these populations provide contrasting patterns, and sometime conflicting results. Many factors could explain variations in data reported in this paper including the mental health-migration interface, differences in the operational definition and measurement of mental disorders within and between countries. Nonetheless, well-known risk factors that could explain the observed differential pattern in mental disorders in Sub-Saharan Africa and China are similar, but manifest multi-dimensionally due to differences in socio-political and economic environments.
