The goals of this study were to examine latent growth in a composite index of sexual risk taking (defined in terms of number of sexual partners and condom nonuse) on five occasions between ages 14-15 and 22-23 years, and to identify associations between latent growth parameters and covariates. As part of the Children of the National Longitudinal Survey of Youth-1979 (CNLSY-79), 740 adolescents provided data at two-year intervals between 1994 and 2004. Latent growth models revealed quadratic growth in youths' sexual risk taking. High initial levels of risk were attributable to early adolescent family structure, the expectation of teenage parenthood, early autonomy from parents, young age at dating initiation, and delinquency. Linear and quadratic growth terms were explained by early adolescent family structure, perceived academic competence, substance use, and delinquency. These associations persisted when time-varying covariates of other contraceptive use and relationship status were modeled.
本研究的目的是考察14至15岁到22至23岁之间五个时间点上性冒险行为综合指数（根据性伴侣数量和不使用避孕套来定义）的潜在增长情况，并确定潜在增长参数与协变量之间的关联。作为全国青年纵向调查1979年儿童样本（CNLSY - 79）的一部分，740名青少年在1994年至2004年期间每隔两年提供一次数据。潜在增长模型显示，青少年的性冒险行为呈二次增长。高初始风险水平归因于青少年早期的家庭结构、对青少年成为父母的期望、较早脱离父母的自主状态、开始约会时的年龄较小以及犯罪行为。线性和二次增长项可由青少年早期的家庭结构、感知到的学业能力、物质使用和犯罪行为来解释。当对其他避孕措施使用和恋爱状况的随时间变化的协变量进行建模时，这些关联仍然存在。
