Labor migration and HIV risk: a systematic review of the literature.

To inform the development of multilevel strategies for addressing HIV risk among labor migrants, 97 articles from the health and social science literatures were systematically reviewed. The study locations were Africa (23 %), the Americas (26 %), Europe (7 %), South East Asia (21 %), and Western Pacific (24 %). Among the studies meeting inclusion criteria, HIV risk was associated with multilevel determinants at the levels of policy, sociocultural context, health and mental health, and sexual practices.
