Chlamydia and Gonorrhea Infections in HIV-positive Women in Urban Lusaka, Zambia

BACKGROUND: Sexually transmitted infections (STIs) remain an important public health issue in sub-Saharan Africa. STIs in HIV-positive women are associated not only with gynecological complications but with increased risk of HIV transmission to HIV-negative partners and newborns. AIMS: The aims of this study are to determine the prevalence of chlamydia (CT) and gonorrhea (GC) and examine the demographic characteristics and risk behaviors associated with these STIs in a group of HIV-positive women in Lusaka, Zambia. SETTINGS AND DESIGN: Cross-sectional study of a sample of HIV-infected women enrolled in two large studies conducted in urban Lusaka, Zambia. MATERIALS AND METHODS: HIV-seropositive women (n = 292) were assessed for demographic and behavioral risk factors and tested for CT and GC. Univariate analysis was used to determine the demographic characteristics and risk behaviors associated with having CT or GC. RESULTS: The identified prevalence of CT was 1% and of GC was 1.4%. There was an association of CT/GC with the use of alcohol before sex (OR = 9.I, CI = 0.59-0.15, P = 0.03). CONCLUSIONS: Rates of CT and GC are described in this sample of HIV-positive women. While being in HIV care may serve to increase medical care and condom use, alcohol use should be addressed in this population.
