目的：虽然青春期和成年早期性表达的出现几乎是普遍的，但人们对性表达的起始模式知之甚少。方法：我们使用潜在类别分析，根据口交、肛交和阴道性交的种类、时间、间隔和顺序，将国家青少年健康纵向研究（Add Health）第一波和第四波的 12,194 名受访者分为五个类别之一。按生物性别分层的多项逻辑回归模型检查了社会人口特征和阶级成员之间的关联。结果：大约一半的受访者遵循的模式主要是首先开始阴道性行为，平均开始年龄约为 16 岁，第一次和第二次行为开始之间的间隔 >1 年；近三分之一的人稍晚开始性活动，但在同一年内报告了第一次口交和阴道性交的经历。以推迟性活动、仅开始一种行为或青少年开始肛交为特征的课程要少见得多。与白人受访者相比，黑人受访者更有可能出现在以首先进行阴道性交为特征的班级中。来自较低社会经济背景的受访者更有可能属于以早期/非典型起始模式为特征的类别。结论：少数典型和非典型模式捕捉到了青春期性行为的出现，但这些模式揭示了新兴性行为的不同元素之间的复杂关联，应在未来的研究中予以考虑。 (C) 2012 年青少年健康与医学协会。版权所有。
Purpose: Although the emergence of sexual expression during adolescence and early adulthood is nearly universal, little is known about patterns of initiation.Methods: We used latent class analysis to group 12,194 respondents from waves I and IV of the National Longitudinal Study of Adolescent Health(Add Health) into one of five classes based on variety, timing, spacing, and sequencing of oral-genital, anal, and vaginal sex. Multinomial logistic regression models, stratified by biological sex, examined associations between sociodemographic characteristics and class membership.Results: Approximately half of respondents followed a pattern characterized predominately by initiation of vaginal sex first, average age of initiation of approximately 16 years, and spacing of >1 year between initiation of the first and second behaviors; almost one-third initiated sexual activity slightly later but reported first experiences of oral-genital and vaginal sex within the same year. Classes characterized by postponement of sexual activity, initiation of only one type of behavior, or adolescent initiation of anal sex were substantially less common. Compared with white respondents, black respondents were more likely to appear in classes characterized by initiation of vaginal sex first. Respondents from lower socioeconomic backgrounds were more likely to be in classes distinguished by early/atypical patterns of initiation.Conclusions: A small number of typical and atypical patterns capture the emergence of sexual behavior during adolescence, but these patterns reveal complex associations among different elements of emerging sexuality that should be considered in future research.
