Data on HIV infection in sub-Saharan Africa show high prevalences in key populations. The objectives of this study were to measure the prevalence of HIV, syphilis and factors associated with HIV infection among men who have sex with men (MSM) and female sex workers (FSW) in Togo.
We conducted a cross-sectional study targeting MSM and FSW in the 6 health regions of Togo in 2022. Respondent-Driving Sampling (RDS) was used. Sociobehavioral, HIV and syphilis seroprevalence data were collected and expressed as percentages of balanced risks.
A total of 2 110 MSM and 3 221 FSW were included in our study. Half of the MSM (53.3%) and FSW (49.7%) were aged between 15 and 24 years. The weighted prevalence of HIV was estimated at 8.7% (95% CI: 7.5%-9.9%) among MSM and 5.8% (95% CI: 5%-6.6%) among FSW. Syphilis incidence was 0.6% (95% CI: 0.3%-0.9%) and 0.2% (95% CI: 0%-0.3%), respectively in MSM and FSW. In multivariate analysis, MSM with: an age over 25 years (OR = 1.71; 1,96: p = 10); a notion of condom tear in the last twelve months (OR = 1.26: p = 0.001), and more than two male sexual partners in the last six months (OR = 1.96: p = 10), would be at greater risk of contracting HIV. FSW with at least one sign of sexually transmitted infections (STI) in the last six months were at greater risk of contracting HIV than those with no sign of STI (OR = 1.24: p = 10).
The results of our study show that HIV prevalence is high in Togo among MSM and FSW. Efforts must be redoubled to create a more favorable socio-cultural and legal environment for these populations in order to achieve a greater impact from HIV control interventions.
撒哈拉以南非洲地区的艾滋病毒感染数据显示，关键人群中的感染率很高。本研究的目的是测量多哥男男性行为者（MSM）和女性性工作者（FSW）中艾滋病毒、梅毒的流行率以及与艾滋病毒感染相关的因素。
2022年，我们在多哥的6个健康区域针对男男性行为者和女性性工作者开展了一项横断面研究。采用应答者驱动抽样（RDS）方法。收集了社会行为、艾滋病毒和梅毒血清流行率数据，并以平衡风险的百分比表示。
我们的研究共纳入了2110名男男性行为者和3221名女性性工作者。一半的男男性行为者（53.3%）和女性性工作者（49.7%）年龄在15至24岁之间。男男性行为者中艾滋病毒的加权流行率估计为8.7%（95%置信区间：7.5%-9.9%），女性性工作者中为5.8%（95%置信区间：5%-6.6%）。男男性行为者和女性性工作者的梅毒发病率分别为0.6%（95%置信区间：0.3%-0.9%）和0.2%（95%置信区间：0%-0.3%）。在多变量分析中，年龄超过25岁的男男性行为者（比值比=1.71；95%置信区间：1.96：p = 10）、在过去十二个月中有避孕套破裂情况的（比值比=1.26：p = 0.001）以及在过去六个月中有两个以上男性性伴侣的（比值比=1.96：p = 10）感染艾滋病毒的风险更高。在过去六个月中至少有一次性传播感染（STI）迹象的女性性工作者感染艾滋病毒的风险高于没有性传播感染迹象的女性性工作者（比值比=1.24：p = 10）。
我们的研究结果表明，多哥的男男性行为者和女性性工作者中艾滋病毒流行率很高。必须加倍努力，为这些人群创造更有利的社会文化和法律环境，以便在艾滋病毒控制干预措施中取得更大成效。
