Condom access: Associations with consistent condom use among female sex workers in two northern border cities of Mexico.

To determine whether condom access is associated with consistent condom use among female sex workers (FSWs) in Tijuana and Ciudad Juarez, between 2004 and 2006 we administered a questionnaire to 924 FSWs who reported unprotected sex with a client in the past 2 months. Of these women, 43% reported consistent ("often" or "always") condom use, 74% said condoms were available, and 38% reported having access to free condoms. In a logistic regression, factors positively associated with consistent condom use were condom availability (adjusted odds ratio [AOR] = 2.00; 95% confidence interval [CI]: 1.32-3.03), condom affordability (AOR = 1.72; 95% CI: 1.25-2.38) and self-efficacy (AOR = 2.16; 95% CI: 1.54-3.04). Factors inversely associated with consistent condom use included poor financial status (AOR = 0.65; 95% CI: 0.47-0.90), methamphetamine use (AOR = 0.58; 95% CI: 0.40-0.83), alcohol use (AOR = 0.68; 95% CI: 0.49-0.96), and recent injection drug use (AOR = 0.62; 95% CI: 0.39-0.97). While increased condom availability may improve condom use among FSWs in general, interventions to broaden condom use among lower income and drug-using FSWs are critically needed.
