To estimate the prevalence and factors associated with HIV and five other STIs among outdoor female sex workers (OSFW) and indoor FSW (IFSW).
Cross-sectional survey using respondent-driven sampling methodology. Participants answered a bio-behavioural questionnaire and were tested for (NG), (CT), (TV), syphilis (lifetime contact) and (MG). Weighted HIV and other STIs prevalence and 95% CIs were calculated. Weighted multivariate logistic regression was performed to identify factors associated with having at least one STI (including HIV).
Between October 2017 and July 2018, 385 FSW participants were recruited, among whom 206 (53.5%) were IFSW and 179 (46.5%) were OFSW. The mean age was 31.4 years. Weighted HIV prevalence was 3.1% (95% CI 1.5 to 7.0). Weighted prevalence of other STIs was: 4.1% (95% CI 2.2 to 8.0) for NG, 8.8% (95% CI 5.9 to 13.0) for CT, 12.7% (95% CI 8.6 to 18.0) for TV, 13.9% (95% CI 9.9 to 19.0) for syphilis (lifetime contact) and 14.9% (95% CI 10.5 to 21.0) for MG. STI prevalence was significantly higher among OFSW for CT, TV and MG (p<0.001). In total, 43.2% of the participants had at least one HIV/STI. Factors associated with having HIV/STI were being an OFSW (OR 3.29; 95% CI 1.72 to 6.27); being registered in another Russian region (2.61 (95% CI 1.05 to 6.48)); having never been tested for HIV (2.51 (95% CI 0.98 to 6.41)) and having a low level of knowledge regarding HIV transmission (4.88 (95% CI 0.96 to 24.78)).
Prevalence of HIV and STIs was high among FSW in Moscow. OFSW were more vulnerable to STIs. There is an urgent need to tailor programmes for sexual and reproductive health for FSW in Russia.
估计户外女性性工作者（OSFW）和室内女性性工作者（IFSW）中 HIV 和其他五种性传播感染（STI）的流行率及相关因素。
采用应答驱动抽样方法进行横断面调查。参与者回答了一份生物行为问卷，并接受了淋病奈瑟菌（NG）、沙眼衣原体（CT）、梅毒（TV）、梅毒（lifetime contact）和支原体（MG）的检测。计算了加权 HIV 和其他 STI 的流行率和 95%置信区间（CI）。采用加权多变量逻辑回归分析确定与至少有一种 STI（包括 HIV）相关的因素。
2017 年 10 月至 2018 年 7 月期间，共招募了 385 名 FSW 参与者，其中 206 名（53.5%）为 IFSW，179 名（46.5%）为 OFSW。平均年龄为 31.4 岁。加权 HIV 流行率为 3.1%（95%CI 1.5%至 7.0%）。其他 STI 的加权流行率分别为：NG 为 4.1%（95%CI 2.2%至 8.0%）、CT 为 8.8%（95%CI 5.9%至 13.0%）、TV 为 12.7%（95%CI 8.6%至 18.0%）、梅毒（lifetime contact）为 13.9%（95%CI 9.9%至 19.0%）和 MG 为 14.9%（95%CI 10.5%至 21.0%）。CT、TV 和 MG 的 STI 流行率在 OFSW 中明显更高（p<0.001）。共有 43.2%的参与者至少有一种 HIV/STI。与 HIV/STI 相关的因素包括 OFSW（OR 3.29；95%CI 1.72 至 6.27）；在俄罗斯其他地区注册（2.61（95%CI 1.05 至 6.48））；从未接受过 HIV 检测（2.51（95%CI 0.98 至 6.41））和对 HIV 传播的了解程度较低（4.88（95%CI 0.96 至 24.78））。
莫斯科的 FSW 中 HIV 和 STI 的流行率很高。OFSW 更容易受到 STI 的影响。迫切需要为俄罗斯的 FSW 制定性健康和生殖健康方案。
