Preadolescent friendships and early teenage dating relationships have implications for adolescent sexual initiation that may differ by race and gender.
Data on participants in the National Longitudinal Survey of Youth and their children are used to profile friendship and dating patterns among a sample of youth born to relatively young mothers. Logistic regression analyses examine whether these patterns predict early sexual initiation, and whether there are differences associated with gender and race.
As youth moved from late childhood to mid-adolescence, they shifted from having almost exclusively same-sex, same-grade friends to having more relationships with persons who are of the opposite sex and older. By ages 15-16,34% had had sexual intercourse; the proportion was significantly higher among blacks (45%) than among others (31%). Most adolescents reported neither frequent dating nor a steady partner by ages 15-16, although the prevalence of such reports was related to friendship patterns in late childhood. Twelve percent of youth who initiated sex in early adolescence did so outside of a dating relationship. For most subgroups examined, the odds of initiating intercourse during early adolescence were associated with going steady, but not with frequency of dating.
Prior social networking is an important element in predicting early sexual activity. Overall, youth whose mothers gave birth at young ages remain sexually inexperienced into middle adolescence, but certain subgroups are more likely than others to initiate early sexual activity.
青春期前的友谊和青少年早期的恋爱关系对青少年的性初次体验有影响,且这种影响可能因种族和性别而异。
利用全国青年纵向调查中参与者及其子女的数据,对相对年轻母亲所生的青少年样本中的友谊和恋爱模式进行描述。逻辑回归分析检验这些模式是否能预测过早的性初次体验,以及是否存在与性别和种族相关的差异。
随着青少年从童年晚期步入青春期中期,他们从几乎只有同性、同年级的朋友转变为与更多异性及年龄较大的人建立关系。到15 - 16岁时,34%的人有过性行为;黑人中的这一比例(45%)显著高于其他种族(31%)。大多数青少年在15 - 16岁时既没有频繁约会也没有固定伴侣,尽管此类报告的发生率与童年晚期的友谊模式有关。在青春期早期开始性行为的青少年中,12%是在没有恋爱关系的情况下进行的。对于所研究的大多数亚组,青春期早期开始性交的几率与有固定伴侣有关,但与约会频率无关。
先前的社交网络是预测过早性活动的一个重要因素。总体而言,母亲在年轻时生育的青少年在进入青春期中期时仍缺乏性经验,但某些亚组比其他亚组更有可能过早开始性活动。
