This study used an event-based approach to understand condom use in a probability sample of 309 homeless youth recruited from service and street sites in Los Angeles County. Condom use was significantly less likely when hard drug use preceded sex, the relationship was serious, the partners talked about "pulling out", or sex occurred in a non-private place (and marginally less likely when heavier drinking preceded sex, or the partnership was monogamous or abusive). Condom use was significantly more likely when the youth held positive condom attitudes or were concerned about pregnancy, the partners talked about condom use, and the partners met up by chance. This study extends previous work by simultaneously examining a broad range of individual, relationship, and contexual factors that may play a role in condom use. Results identify a number of actionable targets for programs aimed at reducing HIV/STI transmission and pregnancy risk among homeless youth.
本研究采用基于事件的方法，在洛杉矶县的服务和街头场所招募的 309 名无家可归的青年中抽取了一个概率样本，以了解他们使用避孕套的情况。当使用硬毒品后发生性行为、关系严重、伴侣讨论“拔出”、或在非私人场所发生性行为时，使用避孕套的可能性显著降低（当性行为前饮酒量较大、或伴侣关系是一夫一妻制或虐待关系时，这种可能性也会适度降低）。当青年对避孕套持有积极态度或担心怀孕、伴侣讨论使用避孕套、以及伴侣偶然相遇时，使用避孕套的可能性显著增加。本研究通过同时检查可能在避孕套使用中发挥作用的广泛的个人、关系和背景因素，扩展了之前的研究。研究结果确定了一些可操作的目标，以针对无家可归的青年减少 HIV/性传播感染和怀孕风险的项目。
