生命史理论（Life History Theory， LHT）是进化生物学的一个分支，它描述了生物体如何根据环境条件最大化其繁殖成功率。这一理论表明，具有挑战性的环境条件会导致青春期早熟，这反过来又预示着高风险的性行为。虽然在女性青少年中得到了很大程度的证实，但在男性青少年中得到的结果却不一致。我们测试了一组基于LHT的预测，其中375名非裔美国男性青年从11岁到16岁进行了三次评估。假设11岁时严酷的、不可预测的社区环境和严酷的、不一致的或不规范的父母教育可以预测13岁时的青春期成熟；假设青春期成熟可以预测危险的性行为，包括性交的早期开始，性活动中的物质使用以及终生性伴侣的数量。结果与我们的假设一致。在非裔美国男性青年中，社区环境是一个适度但显著的青春期时间预测因子。在负性情绪高的青少年中，父母教养和社区因素对青春期发育时间均有预测作用。13岁的青春期时间预示着16岁时危险的性行为。环境对性危险行为的影响是否由青春期时间介导的分析结果并不显著。这表明，虽然进化机制可能通过环境影响敏感青少年的青春期发育，但预测性风险行为的因素取决于青春期成熟的时间，而不是LHT所显示的。
Life History Theory (LHT), a branch of evolutionary biology, describes how organisms maximize their reproductive success in response to environmental conditions. This theory suggests that challenging environmental conditions will lead to early pubertal maturation, which in turn predicts heightened risky sexual behavior. Although largely confirmed among female adolescents, results with male youth are inconsistent. We tested a set of predictions based on LHT with a sample of 375 African American male youth assessed three times from age 11 to age 16. Harsh, unpredictable community environments and harsh, inconsistent, or unregulated parenting at age 11 were hypothesized to predict pubertal maturation at age 13; pubertal maturation was hypothesized to forecast risky sexual behavior, including early onset of intercourse, substance use during sexual activity, and lifetime numbers of sexual partners. Results were consistent with our hypotheses. Among African American male youth, community environments were a modest but significant predictor of pubertal timing. Among those youth with high negative emotionality, both parenting and community factors predicted pubertal timing. Pubertal timing at age 13 forecast risky sexual behavior at age 16. Results of analyses conducted to determine whether environmental effects ons exual risk behavior were mediated by pubertal timing were not significant. This suggests that, although evolutionary mechanisms may affect pubertal development via contextual influences for sensitive youth, the factors that predict sexual risk behavior depend lesson pubertal maturation than LHT suggests.
