We examined associations between timing of first alcohol use and first sexual intercourse in adolescent males and potential differences in observed associations between males and females.
Data were drawn from 4,079 male and 4,059 female participants of the National Longitudinal Study of Youth 1997, aged 12-16 years at the first assessment. Cox proportional hazards regression models were estimated predicting age at first sexual intercourse from age at first alcohol use, without and with adjustment for correlated sociodemographic and individual- and family-level risk factors. Analyses were conducted separately for males and females, with interactions between alcohol use and respondent sex (female vs. male) modeled in subsidiary analyses.
Onset of first drink was strongly predictive of earlier sexual intercourse for both males and females, with effects of drinking most pronounced for females during early adolescence.
Results highlight age at first alcohol use as an important predictor of sexual onset in male as well as female adolescents and suggest that effective prevention efforts focusing on delay of sexual intercourse might also focus on delay on alcohol use.
我们研究了青少年男性首次饮酒与首次性行为之间的关联，以及男性和女性之间观察到的关联存在差异的原因。
本研究的数据来自于全国青少年纵向研究 1997 年的 4079 名男性和 4059 名女性参与者，他们在第一次评估时的年龄为 12-16 岁。使用 Cox 比例风险回归模型，从首次饮酒年龄预测首次性行为年龄，在没有和有相关社会人口学以及个体和家庭层面风险因素调整的情况下分别对男性和女性进行分析，并在次要分析中对饮酒与受访者性别（女性与男性）之间的相互作用进行建模。
首次饮酒与男性和女性的早期性行为呈强相关，且饮酒对女性在青春期早期的影响最为显著。
研究结果突出了首次饮酒年龄是男性和女性青少年性开始的重要预测因素，并表明，以延迟性行为为重点的有效预防措施也可能侧重于延迟饮酒。
