Little is known regarding whether partner characteristics explain sex differences in sexually transmitted infection (STI) rates in nonclinic-based, school-aged African American youth.
A random digit dial household sample of 14- to 19-year-old youth in San Francisco reported the total number, age, race, and perceived history of incarceration, gang membership, and level of sexual activity of their partners. Youth were tested for gonorrhea and chlamydia.
Female participants were more likely than male participants to have a partner who was older or had been incarcerated and less likely to have a non-African American partner. Controlling for partner number, female's odds ratio (OR) for having an STI was 1.39 (95% confidence interval [CI] = 0.98-1.98; P = 0.07). Controlling for partner incarceration and number of partners, the borderline sex difference was eliminated (OR = 1.07; 95% CI = 0.70-1.63).
Sex differences in STI rates among African American adolescents may be determined more by the risk of the partner than the risk of the individual.
对于在非诊所环境下的学龄非裔美国青少年中，性伴侣特征是否能解释性传播感染（STI）率的性别差异，我们知之甚少。
对旧金山14至19岁青少年进行随机数字拨号家庭抽样调查，这些青少年报告了其性伴侣的总数、年龄、种族，以及他们所认为的伴侣的监禁史、帮派成员身份和性活动水平。对青少年进行淋病和衣原体检测。
女性参与者比男性参与者更有可能拥有年龄较大或有过监禁史的伴侣，而拥有非非裔美国伴侣的可能性较小。在控制性伴侣数量后，女性感染性传播感染的优势比（OR）为1.39（95%置信区间[CI]=0.98 - 1.98；P = 0.07）。在控制伴侣监禁史和伴侣数量后，临界的性别差异消失了（OR = 1.07；95% CI = 0.70 - 1.63）。
非裔美国青少年中性传播感染率的性别差异可能更多地由性伴侣的风险而非个体自身的风险所决定。
