目的利用聚类分析方法确定青少年HIV感染风险概况。方法对15-21岁有无保护措施性行为史的青少年（N = 1153）进行5个风险领域（无保护措施性行为、酒精/大麻使用、其他药物使用、精神健康危机和被捕/辍学）以及人口统计学、环境和行为变量的评估。结果聚类分析显示男性和女性的单独三聚类解决方案。在男性中，集群的特点是(a)精神健康危机和无保护的性行为，N酒精/大麻使用和无保护的性行为，以及(c)风险较低。在女性中，各组别的区别是(a)无保护的性行为，(b)药物使用和精神健康危机，以及(c)风险较低。聚类隶属度与性风险相关的次要变量相关。结论：即使在高危青少年人群中，也存在一些特定风险因素共同发生的亚群体，特别是无保护的性行为、精神健康危机和药物使用。这些模式表明，有效的艾滋病毒预防干预措施可能需要针对一些青少年的精神健康和/或药物滥用与性风险之间的关联。
Objective To use cluster analysis to determine profiles of adolescents at risk for HIV. Methods Adolescents 15-21 years old (N = 1153) with a history of unprotected sex were assessed in five domains of risk (unprotected sex, alcohol/marijuana use, other drug use, mental health crises, and arrest/school dropout) as well as demographic, contextual, and behavioral variables. Results Cluster analysis revealed separate three-cluster solutions for males and females. Among males, clusters were characterized by (a) mental health crises and unprotected sex, N alcohol/marijuana use and unprotected sex, and (c) lower risk. Among females, clusters were distinguished by (a) unprotected sex, (b) substance use and mental health crises, and (c) lower risk. Cluster membership was associated with secondary variables related to sexual risk. Conclusions Even within populations of high-risk adolescents, subgroups exist for which specific risk factors co-occur, particularly unprotected sex, mental health crises, and substance use. These patterns suggest that effective HIV prevention interventions may need to target the association between mental health and/or substance abuse with sexual risk for some adolescents.
