BACKGROUND: To investigate the association between migration and HIV infection among migrant and nonmigrant men and their rural partners. GOAL: The goal was to determine risk factors for HIV-1 infection in South Africa. STUDY DESIGN: This was a cross-sectional study of 196 migrant men and 130 of their rural partners, as well as 64 nonmigrant men and 98 rural women whose partners are nonmigrant. Male migrants were recruited at work in two urban centers, 100 km and 700 km from their rural homes. Rural partners were traced and invited to participate. Nonmigrant couples were recruited for comparison. The study involved administration of a detailed questionnaire and blood collection for HIV testing. RESULTS: Testing showed that 25.9% of migrant men and 12.7% of nonmigrant men were infected with HIV ( P= 0.029; odds ratio = 2.4; 95% CI = 1.1-5.3). In multivariate analysis, main risk factors for male HIV infection were being a migrant, ever having used a condom, and having lived in four or more places during a lifetime. Being the partner of a migrant was not a significant risk factor for HIV infection among women; significant risk factors were reporting more than one current regular partner, being younger than 35 years, and having STD symptoms during the previous 4 months. CONCLUSION: Migration is an independent risk factor for HIV infection among men. Workplace interventions are urgently needed to prevent further infections. High rates of HIV were found among rural women, and the migration status of the regular partner was not a major risk factor for HIV. Rural women lack access to appropriate prevention interventions, regardless of their partners' migration status.
