Females who ever had vaginal sex were interviewed annually in their first two years of college (n=386, ages 17 to 20 at study outset) and asked about risky sex behaviors and substance use. In year one, 60.2%(wt) had intoxicated sex, 31.4%(wt) had multiple sex partners, and 48.9%(wt) had unprotected sex (i.e., without a condom). At follow-up, high rates of persistence (86.0%, 52.7%, 78.8% respectively) and initiation (36.0%, 23.9%, 41.8%) were observed. In multiple logistic regression analyses, drug use and drinking were independently associated with having multiple sex partners. Intoxicated sex independently predicted condom non-use and multiple sex partners, and appeared to mediate the relationship between substance use and multiple sex partners. Implications for prevention and future research are discussed.
曾有过阴道性行为的女性在大学的头两年每年接受访谈(n = 386,研究开始时年龄为17至20岁),并被问及危险性行为和药物使用情况。在第一年,60.2%(加权)有醉酒性行为,31.4%(加权)有多个性伴侣,48.9%(加权)有无保护性行为(即未使用避孕套)。在随访中,观察到高持续率(分别为86.0%、52.7%、78.8%)和高起始率(分别为36.0%、23.9%、41.8%)。在多项逻辑回归分析中,药物使用和饮酒与有多个性伴侣独立相关。醉酒性行为独立预测不使用避孕套和有多个性伴侣,并且似乎介导了药物使用与多个性伴侣之间的关系。文中讨论了预防意义和未来研究方向。
