Methamphetamine use is once again on the rise among sexual and gender minorities who have sex with men (SGMSM).
Baseline and 12-month data are taken from an ongoing cohort study of n = 4786 SGMSM aged 16-49 at risk for HIV from across the United States. Participants completed annual online surveys and at-home HIV testing (oral fluid samples returned through mail).
Overall, 2.47 per 100 persons seroconverted over 12 months. In addition, 13.8% of participants reported any methamphetamine use over the 12-month study period. Nearly three-fourths (74.7%; 422 of 565) of those who reported using methamphetamine at baseline were persistent users at 12 months. In adjusted analyses, compared with those who did not use methamphetamine, incident methamphetamine users (ie, those who indicated use between baseline and follow-up) and persistent methamphetamine users had significantly higher odds of HIV seroconverting (adjusted odds ratio = 3.95, 95% confidence interval: 1.64 to 9.47; and 7.11, 4.53 to 11.17, respectively). Persistent methamphetamine users accounted for one-third of all observed HIV seroconversions (41 of 115).
Among SGMSM at elevated risk for HIV, persistent methamphetamine use was prevalent and associated with substantially amplified risk for HIV seroconversion. Expanded efforts are needed to test implementation strategies for scalable, evidence-based interventions to reduce HIV risk in SGMSM who use methamphetamine.
在与男性发生性关系的性少数群体和性别少数群体(SGMSM)中,甲基苯丙胺的使用再次呈上升趋势。
本研究的数据来自一项正在进行的队列研究,共纳入了来自美国各地的 4786 名年龄在 16-49 岁、有感染 HIV 风险的 SGMSM。参与者每年完成在线调查和在家进行 HIV 检测(通过邮件寄回口腔液样本)。
总体而言,在 12 个月内,每 100 人中就有 2.47 人血清转换。此外,在 12 个月的研究期间,13.8%的参与者报告了任何形式的甲基苯丙胺使用。在基线时报告使用甲基苯丙胺的参与者中,近四分之三(74.7%,422/565)在 12 个月时仍为持续使用者。在调整后的分析中,与未使用甲基苯丙胺的参与者相比,新发生的甲基苯丙胺使用者(即在基线和随访期间报告使用甲基苯丙胺的参与者)和持续使用甲基苯丙胺的参与者 HIV 血清转换的可能性显著更高(调整后的优势比分别为 3.95,95%置信区间:1.64 至 9.47;7.11,4.53 至 11.17)。持续使用甲基苯丙胺的参与者占所有观察到的 HIV 血清转换的三分之一(41/115)。
在 HIV 感染风险较高的 SGMSM 中,持续使用甲基苯丙胺很普遍,并且与 HIV 血清转换的风险显著增加有关。需要加大努力,测试实施可扩展、基于证据的干预措施的实施策略,以降低使用甲基苯丙胺的 SGMSM 的 HIV 风险。
