Knowledge on methamphetamine use among a new generation of sexual minority men (SMM) is limited. This study describes the event-level patterns of methamphetamine use and characteristics of methamphetamine users across time among Millennial SMM emerging into adulthood.
A prospective cohort study was conducted in two waves: 2009-2014 (Wave I) and 2014-2019 (Wave II) in the New York City metropolitan area. A total of 600 Millennial SMM ages 18-19 years were recruited for Wave I. A total of 665 SMM ages 22-23 years were recruited for Wave II, of which 41.2% (n = 274) were retained from Wave I. The Timeline Followback assessment was conducted every six months to record event-level drug use in the 30 days prior to the visit.
A total of 5.4% of participants of between the ages of 18-27 reported methamphetamine use throughout the study period. The average number of days of methamphetamine use was significantly higher among racial/ethnic minority men in Wave II (F = 4.34, p = 0.0029). We found methamphetamine use occurred more often on weekend days and same-day use of methamphetamine occurred most often with cannabis and gamma-hydroxybutyrate. Usage of methamphetamine was significantly greater among SMM in Wave II who by design were older than Wave I.
We have identified differences in methamphetamine use by race/ethnicity. Weekend use and poly-drug use were common among methamphetamine-using SMM. Data indicate differential use in the population and that attempts to address this addictive behavior must be linked to other drug use and socialization among young SMM.
关于新一代性少数男性（SMM）使用甲基苯丙胺的了解有限。本研究描述了千禧一代SMM步入成年期后，甲基苯丙胺使用的事件层面模式以及不同时间点甲基苯丙胺使用者的特征。
在纽约市大都市区进行了一项前瞻性队列研究，分两波进行：2009 - 2014年（第一波）和2014 - 2019年（第二波）。第一波招募了600名年龄在18 - 19岁的千禧一代SMM。第二波招募了665名年龄在22 - 23岁的SMM，其中41.2%（n = 274）是第一波保留下来的。每六个月进行一次时间线回溯评估，以记录访视前30天内事件层面的药物使用情况。
在整个研究期间，18 - 27岁的参与者中有5.4%报告使用过甲基苯丙胺。在第二波中，种族/族裔少数群体男性的甲基苯丙胺平均使用天数显著更高（F = 4.34，p = 0.0029）。我们发现甲基苯丙胺使用在周末更为频繁，且甲基苯丙胺与大麻和γ-羟基丁酸的同日使用最为常见。第二波中按设计年龄比第一波大的SMM使用甲基苯丙胺的情况显著更多。
我们已经确定了甲基苯丙胺使用在种族/族裔方面的差异。在使用甲基苯丙胺的SMM中，周末使用和多药联用很常见。数据表明该人群存在不同的使用情况，并且解决这种成瘾行为的尝试必须与年轻SMM中的其他药物使用和社交情况相关联。
