我们的目标是确定南非约翰内斯堡女性性工作者的艾滋病毒感染率和危险因素。使用采访者填写的问卷对女性性工作者进行了横断面调查。通过标准实验室测试评估了包括艾滋病毒在内的流行性传播感染。在 295 名测试对象中，有 137 名 (46.4%) 被检测出 HIV 感染。安全套使用频率的增加与 HIV 感染呈显着负相关（适度使用的比值比 [OR]=0.21；95% 置信区间 [CI]：[0.09, 0.501；大量使用的 OR = 0. 14；95% CI：[0.06, 0.34]）。年龄 >= 29 岁的性工作者报告的行为模式与年轻工作者显着不同。在年龄 >= 29 岁的女性中，发现与 HIV 感染呈负相关（OR= 0. 16；95% CI：[0.07，0.38]），但仅限于未感染淋病奈瑟菌的女性。除了使用安全套之外，约翰内斯堡性行业的老年女性可能还采取适应性行为策略，以降低感染艾滋病毒的风险。然而，患有淋病的老年性工作者构成了高危人群。
Our objective was to determine the prevalence and risk factors for HIV infection among female sex workers in Johannesburg, South Africa. A crosssectional survey of female sex workers was conducted using interviewer administered questionnaires. Prevalent sexually transmitted infections including HIV were evaluated through standard laboratory testing. HIV infection was identified in 137 (46.4%) of 295 subjects tested. Increasing frequency of condom use was significantly negatively associated with HIV infection (odds ratio [OR] for moderate use=0.21; 95% confidence interval [CI]: [0.09, 0.501; OR for high use = 0. 14; 95 % CI: [0.06, 0.34]). Sex workers aged >= 29 years reported significantly different patterns of behaviour than younger workers. Among women aged >= 29, a negative association with HIV infection (OR= 0. 16; 95% CI: [0.07, 0.38]) was found, but only among those not infected with Neisseria gonorrhoeae. Older women in the Johannesburg sex industry may have adaptive behavioural strategies besides condom usage which reduce their risk of acquiring HIV. However, older sex workers with gonorrhoea constitute a high-risk subgroup.
