Randomized controlled pilot evaluated effect of conditional economic incentives (CEIs) on number of sex partners, condom use, and incident sexually transmitted infections (STIs) among male sex workers in Mexico City. Incentives were contingent on testing free of new curable STIs and/or clinic attendance. We assessed outcomes for n = 227 participants at 6 and 12 months (during active phase with incentives), and then at 18 months (with incentives removed). We used intention-to-treat and inverse probability weighting for the analysis. During active phase, CEIs increased clinic visits (10-13 percentage points) and increased condom use (10-15 percentage points) for CEI groups relative to controls. The effect on condom use was not sustained once CEIs were removed. CEIs did not have an effect on number of partners or incident STIs. Conditional incentives for male sex workers can increase linkage to care and retention and reduce some HIV/STI risks such as condomless sex, while incentives are in place.
一项随机对照试点研究评估了条件性经济激励（CEIs）对墨西哥城男男性行为者的性伴侣数量、 condom 使用和新发性传播感染（STIs）的影响。激励措施取决于检测是否有新的可治愈性传播感染和/或诊所就诊。我们在 6 个月和 12 个月（激励期）以及 18 个月（激励结束后）对 227 名参与者进行了评估。我们使用意向治疗和逆概率加权进行分析。在激励期内，CEIs 组与对照组相比，增加了诊所就诊次数（10-13 个百分点）和 condom 使用（10-15 个百分点）。一旦取消激励措施， condom 使用的效果就不再持续。CEIs 对性伴侣数量或新发 STIs 没有影响。对男男性行为者的条件性激励可以增加与护理的联系和保留率，并在激励措施实施期间减少一些 HIV/STI 风险，如无 condom 性行为。
