BACKGROUND: The utility of using pre-exposure prophylaxis (PrEP) eligibility assessments to identify eligibility in general populations has not been well studied in sub-Saharan Africa. We used the Rakai Community Cohort Study to conduct a cross-sectional analysis to estimate PrEP eligibility and a cohort analysis to estimate HIV incidence associated with PrEP eligibility. METHODS: Based on Uganda's national PrEP eligibility tool, we defined eligibility as reporting at least one of the following HIV risks in the past 12 months: sexual intercourse with more than one partner of unknown HIV status; nonmarital sex act without a condom; sex engagement in exchange for money, goods, or services; or experiencing genital ulcers. We used log-binomial and modified Poisson models to estimate prevalence ratios for PrEP eligibility and HIV incidence, respectively. FINDINGS: We identified 12,764 participants among whom to estimate PrEP eligibility prevalence and 11,363 participants with 17,381 follow-up visits and 30,721 person-years (pys) of observation to estimate HIV incidence. Overall, 29% met at least one of the eligibility criteria. HIV incidence was significantly higher in PrEP-eligible versus non-PrEP-eligible participants (0.91/100 pys versus 0.41/100 pys; P < 0.001) and independently higher in PrEP-eligible versus non-PrEP-eligible female participants (1.18/100 pys versus 0.50/100 pys; P < 0.001). Among uncircumcised male participants, HIV incidence was significantly higher in PrEP-eligible versus non-PrEP-eligible participants (1.07/100 pys versus 0.27/100 pys; P = 0.001), but there was no significant difference for circumcised male participants. INTERPRETATION: Implementing PrEP as a standard HIV prevention tool in generalized HIV epidemics beyond currently recognized high-risk key populations could further reduce HIV acquisition and aid epidemic control efforts.
背景:在撒哈拉以南非洲,使用暴露前预防(PrEP)资格评估来确定一般人群中的资格的实用性尚未得到很好的研究。我们使用 Rakai 社区队列研究进行了横断面分析,以估计 PrEP 的资格,并进行了队列分析以估计与 PrEP 资格相关的 HIV 发病率。
方法:根据乌干达的国家 PrEP 资格工具,我们将以下至少一项过去 12 个月中的 HIV 风险定义为符合资格:与不明 HIV 状况的多个伴侣发生性关系;无保护措施的非婚姻性行为;为了换取金钱、货物或服务而发生性行为;或经历生殖器溃疡。我们使用对数二项式和修正泊松模型分别估计 PrEP 资格和 HIV 发病率的患病率比。
发现:我们在 12764 名参与者中确定了 PrEP 资格的患病率,在 11363 名参与者中确定了 17381 次随访和 30721 人年(pys)的观察结果,以估计 HIV 发病率。总体而言,29%的人符合至少一项资格标准。PrEP 合格参与者的 HIV 发病率明显高于非 PrEP 合格参与者(0.91/100 pys 与 0.41/100 pys;P<0.001),并且在 PrEP 合格女性参与者中也明显高于非 PrEP 合格参与者(1.18/100 pys 与 0.50/100 pys;P<0.001)。在未割礼的男性参与者中,PrEP 合格参与者的 HIV 发病率明显高于非 PrEP 合格参与者(1.07/100 pys 与 0.27/100 pys;P=0.001),但割礼男性参与者则没有差异。
解释:在目前公认的高危关键人群之外,将 PrEP 作为一种标准的 HIV 预防工具实施,可以进一步减少 HIV 的获得,并有助于控制艾滋病疫情。
