Methamphetamine use is associated with increased HIV/STI infection among men who have sex with men (MSM). From March 2014 through January 2016, 286 methamphetamine-using MSM enrolled in a study to reduce methamphetamine use and sexual risk behaviors. Participants were tested for HIV/STIs at baseline and every 3 months for 9 months. At baseline, 115 participants (40.2%) were HIV-positive; three participants seroconverted (incidence = 2.6/100 person-years). Baseline testing diagnosed 77 STI cases (21 chlamydia, 18 gonorrhea, 38 syphilis); by 9-month follow-up, 71 incident STIs were diagnosed (22 chlamydia, 24 gonorrhea, 25 syphilis); 78% occurred among HIV-positive participants. Despite efforts to reduce sexual risks among methamphetamine-using MSM, HIV/STI prevalence and incidence remain elevated.
使用甲基苯丙胺与男男性行为者（MSM）中艾滋病毒/性传播感染的增加有关。从2014年3月到2016年1月，286名使用甲基苯丙胺的男男性行为者参与了一项旨在减少甲基苯丙胺使用和性风险行为的研究。参与者在基线时以及之后的9个月内每3个月接受一次艾滋病毒/性传播感染检测。在基线时，115名参与者（40.2%）艾滋病毒呈阳性；3名参与者发生血清转化（发病率=2.6/100人年）。基线检测诊断出77例性传播感染病例（21例衣原体感染、18例淋病、38例梅毒）；到9个月随访时，诊断出71例新发性传播感染病例（22例衣原体感染、24例淋病、25例梅毒）；78%发生在艾滋病毒呈阳性的参与者中。尽管努力降低使用甲基苯丙胺的男男性行为者中的性风险，但艾滋病毒/性传播感染的患病率和发病率仍然很高。
