作者研究了第一次阴道性交的年龄与性传播感染（STI）核酸扩增试验阳性之间的关系。在全国青少年健康纵向研究的第3波（2001-2002）中，对9,844名18-26岁的受访者进行了衣原体感染、淋病和滴虫病的全国代表性样本检测。作者使用多元逻辑回归来评估首次性交年龄与这些性传播感染之间的关系，并检查当前年龄，性别，种族和民族的变化。与年龄较大的人相比，首次性交时年龄较小的人发生性传播感染的几率较高，但这种影响随着当前年龄的增加而减弱。例如，13岁时首次性交的18岁青少年发生性传播感染的几率是17岁时首次性交的18岁青少年的两倍多（患病率比值比= 2.25，95%置信区间：1.42，3.59）。相比之下，在13岁时首次性交的24岁人群与在17岁时首次性交的人群中发生性传播感染的几率相同（患病率比值比= 1.11，95%置信区间：0.88，1.39）。因此，较早开始性交与年龄较大的青少年的性传播感染密切相关，但与23岁以上的年轻人无关。
The authors examined the relation between age at first vaginal intercourse and a positive nucleic acid amplification test for sexually transmitted infection (STI). A nationally representative sample of 9,844 respondents aged 18-26 years was tested for chlamydial infection, gonorrhea, and trichomoniasis in wave 3 (2001-2002) of the National Longitudinal Study of Adolescent Health. The authors used multiple logistic regression to assess the relation between age at first sexual intercourse and these STIs and to examine variation by current age, sex, race, and ethnicity. Younger ages at first intercourse were associated with higher odds of STI in comparison with older ages, but the effect diminished with increasing current age. For example, the odds of having an STI for an 18-year-old who first had intercourse at age 13 were more than twice those of an 18-year-old who first had intercourse at age 17 (prevalence odds ratio = 2.25, 95% confidence interval: 1.42, 3.59). In contrast, the odds of having an STI among 24-year-olds with first intercourse at age 13 versus those with first intercourse at age 17 were the same (prevalence odds ratio = 1.11, 95% confidence interval: 0.88, 1.39). Thus, earlier initiation of sexual intercourse is strongly associated with STIs for older adolescents but not for young adults over age 23 years.
