Condom failure (slippage or breakage) has been shown to be associated with HIV seroconversion among men who have sex with men (MSM), but predictors of failure have been poorly elucidated. Of 2592 HIV-seronegative MSM participants in the HIV Network for Prevention Trials (HIVNET) multisite Vaccine Preparedness Study who reported condom use for anal sex in the 6 months before enrollment, condom failure was reported by 16.6%, with failure rates of 2.1/100 episodes of condom usage (2.5 failures/100 episodes for receptive anal sex and 1.9/100 episodes for insertive anal sex). In separate multivariate models evaluating predictors of condom failure reported by the insertive and receptive partners, more frequent condom use was associated with a decreased per-condom failure rate and amphetamine and heavy alcohol use with increased rates in both models. Being employed, having private medical insurance, and using lubricants for >80% of anal sex acts were significantly associated with decreased failure rates in the insertive model. Safer sex counseling should particularly target men of lower socioeconomic status, promote proper and consistent use of condoms with appropriate lubricants, and address the impact of drug use, especially amphetamines and alcohol, on condom failure.
避孕套失败(滑落或破裂)已被证明与男男性行为者(MSM)的HIV血清转化有关,但失败的预测因素尚未得到充分阐明。在预防试验HIV网络(HIVNET)多地点疫苗准备研究中,2592名HIV血清阴性的男男性行为参与者在入组前6个月报告有肛交时使用避孕套,其中16.6%报告避孕套失败,避孕套使用率为2.1/100次(接受肛交的失败率为2.5/100次,插入式肛交的失败率为1.9/100次)。在评估插入方和接受方报告的避孕套失败预测因素的单独多变量模型中,更频繁地使用避孕套与每次避孕套失败率降低相关,而在两个模型中,使用安非他明和大量饮酒与失败率增加相关。在插入方模型中,就业、拥有私人医疗保险以及在超过80%的肛交行为中使用润滑剂与失败率降低显著相关。安全性行为咨询应特别针对社会经济地位较低的男性,促进正确和持续使用带有适当润滑剂的避孕套,并解决药物使用,尤其是安非他明和酒精对避孕套失败的影响。
