Alcohol use behaviors among indigenous migrants: a transnational study on communities of origin and destination.

The association between international and domestic migration and alcohol use among indigenous communities is poorly understood. We explored migration-related factors associated with alcohol use behaviors among an indigenous Mayan, binational population. From January to March 2012, 650 indigenous participants from the high-emigration town of Tunkás in the Mexican state of Yucatán (n = 650) residing in Mexico and California completed surveys. Multivariate logistic regression identified migration-related factors associated with alcohol use behaviors. US migration of shorter duration (<5 years) was independently associated with at-risk drinking (adjusted odds ratio (AOR) 2.34; 95% confidence interval (CI) 1.09-5.03), as was longer-duration domestic migration (≥5 years) (AOR 2.34; 95% CI 1.12-4.87). Ability to speak Maya (AOR 0.26; 95% CI 0.13-0.48) was protective against at-risk drinking. Culturally appropriate alcohol use prevention interventions are needed for domestic and international indigenous Mexican migrants to address alcohol use behavior in the context of migration.
