在过去的三十年中，大多数关于青少年性行为的研究都集中在阴道性交和相关行为，包括避孕和意外怀孕。在这项研究中，我们描述了马里兰州巴尔的摩流行病学定义的人群中阴道性交、口交和肛交的患病率及其相关性。 1998 年至 2002 年间，对小学期间参加行为干预试验的年轻人（18-24 岁）进行了电话采访，以评估他们的性行为。在 1679 名接受采访的受访者中，70.8% 是黑人，55% 是女性。总体而言，93% 的年轻人表示进行过阴道性交，78% 表示接受过口交，57% 表示进行过口交，10% 表示接受肛交。在男性中，27% 的人表示有插入式肛交。黑人比白人更早开始阴道性交；白人女性比黑人女性更早进行口交。在第一个阴道伴侣的年龄与性别和种族/民族之间观察到显着的相互作用。拥有年长伴侣的黑人比拥有同龄或更年轻伴侣的黑人和白人更早开始性行为。我们还观察到老年女性性伴侣与男性较早开始阴道性行为之间的关系。我们的结论是，年长的性伴侣在年轻人的性起始过程中发挥着重要作用。鉴于口交和肛交的发生率，性教育和干预计划应解决这些行为产生意外后果的风险。
Over the past three decades, most research on adolescent sexual behavior has focused on vaginal intercourse and related behaviors, including contraception and unintended pregnancy. In this study, we describe the prevalence and correlates of vaginal, oral, and anal sex in an epidemiologically defined population in Baltimore, Maryland. Young adults (ages 18-24), who had been enrolled in a behavioral intervention trial during elementary school, were interviewed by telephone between 1998 and 2002 to assess their sexual behavior. Of 1679 respondents interviewed, 70.8% were Black and 55% were women. Overall, 93% of the young adults reported vaginal intercourse, 78% reported receiving oral sex, 57% reported performing oral sex, and 10% reported receptive anal intercourse. Among men, 27% reported insertive anal intercourse. Blacks initiated vaginal intercourse at an earlier age than Whites; White women performed oral sex earlier than Black women. Significant interactions were observed between age of first vaginal partner and both gender and race/ethnicity. Blacks with older partners initiated sex at an earlier age than both Blacks with a partner the same age or younger and Whites. We also observed a relationship between older female sex partners and earlier vaginal sex initiation among men. We conclude that older sex partners play an important role in sexual initiation among young adults. In light of the rates of oral and anal sex, sexual education and intervention programs should address the risk for unintended consequences of these behaviors.
