Abstract
OBJECTIVE: To compare HIV prevalence and HIV acquisition risk behaviors between pregnant women residents and migrants. DESIGN: A cross-sectional study of pregnant women of unknown HIV status seeking care at Tijuana General Hospital, Mexico. METHODS: Pregnant women attending the labor and delivery unit or the prenatal clinic had a rapid HIV test drawn, with positive results confirmed by Western blot. Migrants were defined as women who had resided in Tijuana for less than 5 years. RESULTS: Between 2007 and 2008, a total of 3331 pregnant women consented to participate. The HIV seroprevalence did not differ between Tijuana residents (18 of 2502, 0.72%) and migrants (3 of 829, 0.36%, P = .32). In multivariate regression analyses, HIV acquisition risk behaviors included methamphetamine use (adjusted odds ratio [OR]: 6.03, 95% confidence interval [CI]: 2.3-15.8, P < .001) and first presentation at labor (adjusted OR: 5.0, 95% CI: 1.6-15.3, P = .005), adjusted for migrant status, age, and history of sexually transmitted infections. CONCLUSION: The overall HIV seroprevalence was 0.63% and did not differ between Tijuana residents and migrants.
