HIV risk factors among patients with tuberculosis — Botswana 1999

Abstract

To identify factors associated with HIV in Botswana, a standardized questionnaire was administered to 135 tuberculosis patients with known HIV status. HIV-positive patients were more likely than HIV-negative patients to: be female (45% vs 26% (adjusted prevalence odds ratio (aPOR)=3.8, 95% confidence interval (CI)=1.1-12.7)); be 26-35 years old (50% vs 19% (aPOR=2.7, CI=0.7-10.7)); be unmarried (91% vs 71% (aPOR=13.3, CI=2.5-72.7)); have higher income (24% vs 10% (aPOR=8.2, CI=1.6-42.9)); report separation from spouse/partner for work (63% vs 52% (aPOR=1.8, CI=0.5-6.2)); have 2 sex partners other than their regular partner (82% vs 67% (aPOR=1.8, CI=0.5-7.5)); and state that they or their partner drank alcohol before sex (77% vs 55% (aPOR=6.8, CI=1.9-24.1)). Only 22% of respondents used condoms during all of their past 10 sexual encounters. These data provide information for HIV prevention strategies.
