HIV/AIDS-related knowledge and risk behaviors among female sex workers: survey in a city of Guangdong province

Objective：To investigate the HIV/AIDS-related knowledge and risk behaviors among female sex workers in a city of Guangdong Province, and to explore the risk factors associated with condom use, so as to provide evidence for population-based intervention programs. Methods： A total of 305 female sex workers were recruited from the communities by using time-location sampli~lg. The survey was conducted with face-to-face interviews and uniformed questionnaires. Blood samples were collected from these subjects for detection of antibodies against syphilis and AIDS. The risk behaviors related to condom use were analyzed with Logistic regression. Results： The overall rate of awareness was 55.4%. Condoms were used by 89.4% of the subjects in their most recent intercourse with commercial sex partners. A lower rate of condom use was found in these subjects when having sex with regular and transient sex partners than with commercial sex partners. None of the subjects tested positive for human immunodefieiency virus antibody. In contrast, syphilis was detected in 1.0% of the women. Higher payment was an independent risk factor for no-condom sex with commercial partners, and accessibility to interventional programs was a protective factor for condom use. Conclusion： High rate of condom use and low prevalence of HIV and syphilis were found among female sex workers in a city of Guangdong Province. Interventional programs targeting female sex workers may effectively promote the condom use when having sex with a commercial partner.
