目前的研究测试了青春期早期、首次性行为和性冒险的性别特异性途径，正如青少年性发育和行为的综合进化发育模型所指定的那样。在一项对 238 名大约 12-18 岁青少年（n = 129 名女孩和 n = 109 名男孩）进行的前瞻性研究中，我们测试了男孩和女孩的生态压力源、家庭关系、青春期成熟、自我感知的伴侣价值和性冒险之间的纵向关系。与该理论一致，（a）较高水平的家庭和生态压力预示着较早的首次性行为和较大的性冒险； (b) 青春期成熟部分调节了女孩之间的这些关系，但男孩之间没有； (c) 父亲缺席对女性性结果有独特影响，但对男性性结果没有影响； (d) 较高的自我认知择偶价值直接预示着首次性行为的提前，并由此导致更大的性冒险； (e) 青春期成熟与早期性行为之间的关系部分是由男孩较高的自我感知择偶价值所调节的，但女孩则不然。讨论的重点是综合进化发展理论对青少年性健康文献的贡献。
The current study tested sex-specific pathways to early puberty, sexual debut, and sexual risk taking, as specified by an integrated evolutionary developmental model of adolescent sexual development and behavior. In a prospective study of 238 adolescents (n = 129 girls and n = 109 boys) followed from approximately 12-18 years of age, we tested for longitudinal relations between ecological stressors, family relationships, pubertal maturation, self-perceived mate value, and sexual risk taking in both boys and girls. Consistent with the theory, (a) higher levels of familial and ecological stress predicted earlier sexual debut and greater sexual risk taking; (b) pubertal maturation partially mediated these relations among girls but not among boys; (c) father absence had unique effects on female sexual outcomes but not on male sexual outcomes; (d) higher self-perceived mate value directly predicted earlier sexual debut and, through it, greater sexual risk taking; and (e) relations between pubertal maturation and early sexual debut were partially mediated by higher self-perceived mate value in boys but not in girls. Discussion focuses on the contribution of an integrated evolutionary developmental theory to the adolescent sexual health literature.
