We conducted a randomized control trial to evaluate the impact of a novel technology-based intervention on HIV risks and condom use behaviors among Thai men who have sex with men (MSM). Between April 2016 and August 2017, participants aged 18 years and above, and having engaged in unprotected sex in past six months were randomly assigned to control and intervention arm, and received HIV testing at baseline, month 6 and 12. Intervention arm participants engaged in 12-monthly HIV/STI prevention educational sessions delivered via Vialogues.com. Of 76 MSM enrolled, 37 were randomized to intervention and 39 to control arm. Median age was 28 (IQR 24-32) years. Thirty-three (89.2%) intervention arm participants completed all 12-monthly Vialogues sessions. At month 12, intervention arm had higher retention rate ( = 0.029) and higher median percentage of condom use for anal intercourse ( = 0.023) versus control arm. Over the 12-month period, intervention arm reported significant reduction in self-perceived HIV risk ( = 0.001), popper usage ( = 0.002), median number of sexual partners ( = 0.003), and increased median condom use percentage ( = 0.006). Our study highlights that "Vialogues" intervention significantly reduced number of sexual partners and condomless anal intercourse rates among Thai MSM, and has positive implications for reducing epidemic among key populations.
我们开展了一项随机对照试验，以评估一种基于新技术的干预措施对泰国男男性行为者（MSM）的艾滋病毒感染风险和避孕套使用行为的影响。在2016年4月至2017年8月期间，年龄在18岁及以上且在过去六个月内有过无保护性行为的参与者被随机分配到对照组和干预组，并在基线、第6个月和第12个月接受艾滋病毒检测。干预组的参与者参加了通过Vialogues.com提供的为期12个月的艾滋病毒/性传播感染预防教育课程。在登记的76名男男性行为者中，37人被随机分配到干预组，39人被分配到对照组。中位年龄为28岁（四分位间距24 - 32岁）。33名（89.2%）干预组参与者完成了所有12个月的Vialogues课程。在第12个月时，与对照组相比，干预组的保留率更高（P = 0.029），肛交时使用避孕套的中位百分比更高（P = 0.023）。在12个月的时间里，干预组报告自我感知的艾滋病毒感染风险显著降低（P = 0.001），Poppers使用情况显著降低（P = 0.002），性伴侣中位数显著减少（P = 0.003），避孕套使用百分比中位数增加（P = 0.006）。我们的研究强调，“Vialogues”干预措施显著降低了泰国男男性行为者的性伴侣数量和无保护肛交率，对减少重点人群中的疫情具有积极意义。
