Research has established that voluntary medical male circumcision (VMMC) reduces HIV acquisition in heterosexual men by approximately 60%; however, engaging in sexual activity before the wound is healed may attenuate this protective effect. This prospective study included VMMC clients who were circumcised in Kenya between November, 2008 and March, 2010, aged ≥ 18 years, and randomly selected for an interview and genital examination 28-45 days post-VMMC (N = 1,344). At the time of the interview, 91.3% participants were healed. Overall, 30.7% reported engaging in early sexual activity, usually 3-4 weeks post-VMMC. In a multivariable analysis, being married or cohabitating was the strongest predictor of engaging in early sexual activity. Strategies to reduce engaging in sexual activity during the recommended 42-day abstinence period following VMMC should be explored including re-energizing the effort to include female partners in counseling, mass education campaigns, and targeted text messaging programs for VMMC clients.
研究已经证实，男性自愿性包皮环切术（VMMC）可使异性性行为中的男性 HIV 感染率降低约 60%；然而，在伤口未愈合的情况下进行性行为可能会减弱这种保护作用。本前瞻性研究纳入了 2008 年 11 月至 2010 年 3 月期间在肯尼亚接受包皮环切术的 VMMC 客户，年龄≥18 岁，且在 VMMC 后 28-45 天随机选择进行访谈和生殖器检查（N=1344）。在访谈时，91.3%的参与者已经愈合。总体而言，30.7%的参与者报告在早期发生了性行为，通常是在 VMMC 后 3-4 周。在多变量分析中，已婚或同居是发生早期性行为的最强预测因素。应探索减少在 VMMC 后建议的 42 天禁欲期内发生性行为的策略，包括重新加强对女性伴侣进行咨询的努力、大众教育运动，以及针对 VMMC 客户的有针对性的短信服务计划。
