This study explored factors that may be associated with early initiation of sexual activity among adolescents. Using the cumulative risk model, we hypothesized that as exposure to risk factors increases, so does the likelihood of early sexual debut. A sample of 273 (53% girls, 90% European American) adolescents was followed longitudinally from age 13 to 15. The results indicate that, for girls, increased television viewing, low self-esteem, poor parental relationships, living in a non-intact household, higher levels of externalizing behavior (ADHD symptomology), low academic achievement, and parents with low education levels were associated with earlier sexual debut. For boys, advanced pubertal development, increased television viewing, higher rates of externalizing behaviors (ADHD and ODD symptoms), and poor parental relationships were associated with earlier sexual debut. As hypothesized, predictive power increases with the accumulation of these risks; girls are 1.56 times more likely to become sexually active with an increase of only one risk and boys are 1.90 times more likely.
本研究探讨了可能与青少年过早开始性行为相关的因素。我们运用累积风险模型进行假设，即随着接触风险因素的增加，过早首次性行为的可能性也会增加。对273名青少年（53%为女孩，90%为欧美裔）进行了从13岁到15岁的纵向跟踪研究。结果表明，对于女孩而言，看电视时间增加、自尊水平低、亲子关系差、生活在不完整家庭、外化行为（多动症症状）水平较高、学业成绩低以及父母教育水平低与过早首次性行为有关。对于男孩来说，青春期发育提前、看电视时间增加、外化行为（多动症和对立违抗性障碍症状）发生率较高以及亲子关系差与过早首次性行为有关。正如所假设的那样，随着这些风险的累积，预测能力增强；女孩每增加一种风险，性活跃的可能性就会增加1.56倍，男孩则为1.90倍。
