Background The aim of this study was to determine the 3-month efficacy of a single-session, clinic-based intervention promoting condom use for anal and oral sex among HIV-uninfected Black young men who have sex with men (YBMSM).
A pre-post test randomised controlled trial (RCT) was conducted from 2012 to 2015 using a 3-month period of observation. Recruitment and assessment occurred in sexually transmissible infection (STI) clinics. Men were randomised to either the intervention condition (n=142) or a standard-of-care control condition (n=135). The experimental condition comprised a single session of a one-to-one program designed for use in STI clinics. YBMSM completed both baseline and 3-month follow-up assessments. Outcomes measures were condomless anal insertive sex, condomless anal receptive sex and condomless oral sex.
Among men receiving the intervention, 11.2% (n=15) reported any condomless anal insertive sex at follow-up, compared with 20.6% (n=27) among controls (rate ratio=0.54, P=0.04). In addition, 12.0% (n=17) of men receiving the intervention reported any condomless anal receptive sex at follow-up, compared with 21.6% (n=29) among controls (rate ratio=0.55, P=0.03). When combining insertive and receptive anal sex, 18.3% (n=26) of men receiving the intervention reported any condomless sex, compared with 31.1% (n=42) among controls (rate ratio=0.59, P=0.01). Furthermore, 45.8% (n=33) of men receiving the intervention reported any condomless oral sex at follow-up, compared with 63.2% (n=48) among controls (rate ratio=0.72, P=0.03).
This analysis of data from a Phase 3 RCT suggests that a single session of a clinic-based behavioural intervention may effectively promote the consistent use of condoms for anal and oral sex among HIV-uninfected YBMSM. The single-session program may be a valuable counselling tool for use in conjunction with recommended quarterly clinic appointments for YBMSM using pre-exposure prophylaxis.
背景 本研究的目的是确定在基于诊所的单次干预中，促进未感染艾滋病毒的男男性行为黑人青年（YBMSM）在肛交和口交时使用避孕套的3个月疗效。
2012年至2015年进行了一项前后测随机对照试验（RCT），观察期为3个月。招募和评估在性传播感染（STI）诊所进行。男性被随机分为干预组（n = 142）或标准护理对照组（n = 135）。实验组包括在STI诊所使用的一对一项目的单次课程。YBMSM完成了基线和3个月的随访评估。结果指标为无保护肛交插入性行为、无保护肛交接受性行为和无保护口交。
在接受干预的男性中，11.2%（n = 15）在随访时报告有任何无保护肛交插入性行为，而对照组为20.6%（n = 27）（率比 = 0.
