Using approximately 2,000 sibling pairs from the National Longitudinal Survey of Labor Market Experience of Youth, we examine the influence of an older sibling's age at first sexual intercourse on the sexual initiation of a younger sibling. Hypotheses about differences by gender composition of the pair are tested, using a framework derived from social comparison theory and a two-stage failure-time model. Results provide evidence of a direct but modest-sized older sibling effect for white but not black youth. This effect is approximately equal in magnitude for same- and opposite-sex siblings. Little support is offered for the greater salience and association of sexual activity for brother-brother as compared with sister-sister pairs.
我们使用来自全国青年劳动力市场经历纵向调查的约2000对兄弟姐妹，研究年长兄弟姐妹首次性交年龄对年幼兄弟姐妹性初潮的影响。我们使用源自社会比较理论的框架和两阶段失效时间模型，检验了关于配对性别构成差异的假设。结果表明，白人青年存在直接但规模适中的年长兄弟姐妹效应，而黑人青年则不存在。这种效应在同性和异性兄弟姐妹中的大小大致相同。与姐妹配对相比，兄弟配对的性活动显著程度和关联性更高这一观点几乎没有得到支持。
