This study investigated human immunodeficiency virus (HIV) testing and risk behaviors in a longitudinal sample of young men who have sex with men (YMSM).
Data came from the Healthy Young Men's study, comprising five waves of nonexperimental survey data collection every 6 months between February 2005 and January 2008.
Participants were recruited from public venues in Los Angeles County in which YMSM spend time.
A total of 526 participants (24% African-American, 37% white, 39% Latino; mean age, 20.14 years; range, 18?24 years) were enrolled. Retention was 93%.
Testing recency was assessed with a four-point ordinal scale. HIV risk behaviors were operationalized as binary measures of unprotected anal intercourse with multiple partners or partners with unknown or discordant serostatus, club drug use, and illicit drug use over the prior 3 months.
Correlations, Cochran's Q tests, and repeated-measures analysis of variance (ANOVA) were performed in SPSS. Analyses included all data available at each wave.
No significant correlations emerged between testing recency and sex risk at any wave. Repeated-measures ANOVA showed significant positive, linear change in HIV testing recency over time, but no significant changes emerged for sex risk or drug use.
Although participation in testing increased, there was no corresponding change in HIV risk behavior. Initiatives may need to target risk behavior separately and specifically to reduce these behaviors among YMSM.
本研究调查了同性恋男性纵向样本中人类免疫缺陷病毒（HIV）检测和风险行为。
数据来自健康年轻男性研究，包括 2005 年 2 月至 2008 年 1 月期间每 6 个月进行的五次非实验性调查数据收集。
参与者从洛杉矶县的公共场所招募，同性恋男性在这些地方度过时间。
共有 526 名参与者（24%为非裔美国人，37%为白人，39%为拉丁裔；平均年龄 20.14 岁；范围 18-24 岁）被纳入研究。保留率为 93%。
使用四点定序量表评估检测的最近时间。HIV 风险行为通过无保护的与多个伴侣或伴侣血清学状态未知或不一致的肛交、俱乐部药物使用以及过去 3 个月内的非法药物使用的二元措施来操作化。
使用 SPSS 进行了相关性、Cochran's Q 检验和重复测量方差分析（ANOVA）。分析包括每个时间点可用的所有数据。
在任何一个时间点，检测的最近时间与性风险之间均未出现显著相关性。重复测量方差分析显示，HIV 检测的最近时间随时间呈显著的正线性变化，但性风险或药物使用没有出现显著变化。
尽管参与检测的人数有所增加，但 HIV 风险行为并没有相应改变。举措可能需要单独且专门针对风险行为，以减少同性恋男性中的这些行为。
