Female Sex Workers (FSWs) are considered to be at high risk for transmission of Sexually Transmitted Infections (STIs) and are defined as a priority of the national HIV/AIDS response in the Republic of Congo (RoC). However, no data are available regarding STIs in this group. This study aimed to determine the prevalences of HIV, syphilis and hepatitis B and C among FSWs in five cities in the country.
A cross-sectional study was conducted from November 2 2011 to May 15 2012. Participants were recruited in Brazzaville, Pointe-Noire, Dolisie, Nkayi and Pokola using a respondent-driven sampling method.
A total of 805 FSWs were recruited with an average age of 28.31 ± 9.15 years. The overall prevalences of HIV, syphilis, HBV and HCV were 7.50%, 2.20%, 4.20% and 0.70%, respectively. The age groups 35-39 (20.51% [0%-36.93%], = 0.0057) and greater than 40 years (16.67% [0%-34.93%], = 0.016) were positively associated with behaviors at high risk of HIV infection. For syphilis, the most infected age group was the one greater than 40 years, at 6.25% ([1.06% -72.37%] = 0.04). Pointe-Noire was the most infected city for syphilis and HBV, with 5.15% ( = 0.0061) and 4.22% (p˂0.001), respectively. No risk factors were associated with HCV infection. FSWs practicing in mobile prostitution sites had a significantly higher infection rate (2.1% [0%-11.09%] = 0.04).
This study shows that the prevalence of HIV and other STIs in FSWs is high. Therefore, a combination of individual and structural interventions could reduce the risk of an STI "reservoir" among this population.
女性性工作者被认为是性传播感染（STIs）传播的高危人群，在刚果共和国被确定为国家艾滋病毒/艾滋病应对工作的重点对象。然而，关于该群体性传播感染的情况尚无数据。本研究旨在确定该国五个城市女性性工作者中艾滋病毒、梅毒以及乙型和丙型肝炎的感染率。
于2011年11月2日至2012年5月15日开展了一项横断面研究。在布拉柴维尔、黑角、多利西、恩凯伊和波科拉采用应答者驱动抽样方法招募参与者。
共招募了805名女性性工作者，平均年龄为28.31±9.15岁。艾滋病毒、梅毒、乙肝和丙肝的总体感染率分别为7.50%、2.20%、4.20%和0.70%。35 - 39岁年龄组（20.51% [0% - 36.93%]，P = 0.0057）和40岁以上年龄组（16.67% [0% - 34.93%]，P = 0.016）与艾滋病毒感染的高危行为呈正相关。对于梅毒，感染率最高的年龄组是40岁以上，为6.25%（[1.06% - 72.37%]P = 0.04）。黑角是梅毒和乙肝感染率最高的城市，分别为5.15%（P = 0.0061）和4.22%（P˂0.001）。没有风险因素与丙肝感染相关。在流动卖淫场所工作的女性性工作者感染率显著更高（2.1% [0% - 11.09%]P = 0.04）。
本研究表明女性性工作者中艾滋病毒和其他性传播感染的感染率很高。因此，个人干预和结构性干预相结合可降低该人群中性传播感染“储存库”的风险。
