The HIV/AIDS epidemic is disproportionately impacting young African Americans. Efforts to understand and address risk factors for unprotected sex in this population are critical in improving prevention efforts. Situational risk factors, such as relationship type and substance use before sex, are in need of further study. This study explored how established cognitive predictors of risky sexual behavior moderated the association between situational factors and unprotected sex among low-income, African American adolescents. The largest main effect on the number of unprotected sex acts was classifying the relationship as serious (event rate ratio=10.18); other significant main effects were alcohol use before sex, participant age, behavioral skills, and level of motivation. HIV information moderated the effect of partner age difference, motivation moderated the effects of partner age difference and drug use before sex, and behavioral skills moderated the effects of alcohol and drug use before sex. This novel, partnership-level approach provides insight into the complex interactions of situational and cognitive factors in sexual risk taking.
艾滋病毒/艾滋病疫情在非裔美国年轻人中不成比例地造成影响。为了解决这一人群中无保护性行为的风险因素，并改善预防措施，努力了解和解决这些因素至关重要。情境风险因素，如性关系类型和性行为前的物质使用，需要进一步研究。本研究探讨了既定的认知风险性行为预测因素如何调节情境因素与低收入非裔美国青少年无保护性行为之间的关联。对无保护性行为次数影响最大的主要因素是将关系归类为严肃（事件发生率比=10.18）；其他显著的主要影响因素包括性行为前饮酒、参与者年龄、行为技能和动机水平。艾滋病毒信息调节了伴侣年龄差异的影响，动机调节了伴侣年龄差异和性行为前药物使用的影响，行为技能调节了酒精和药物使用的影响。这种新颖的伙伴关系层面的方法提供了对性行为风险中情境和认知因素复杂相互作用的深入了解。
