Receptive anal intercourse has long been recognized as a risk factor for the transmission of HIV and STIs. Most HIV/STI prevention messages continue to emphasize penile-vaginal transmission, so many teens do not recognize anal intercourse as risky sexual behavior. This purpose of this study was to determine the prevalence of anal intercourse, and to describe the relationship between types of sexual relationships (main vs. casual), types of sexual behaviors (vaginal vs. anal sex), and types of contraception used among inner-city sexually experienced adolescents.
Reproductive health histories were obtained from 350 sexually experienced adolescent females aged 12-18 years participating in a 5-year STI acquisition study at an urban health center. Baseline sexual behavior data was analyzed and described using frequencies, percentages and chi-square tests.
41% of teens and 86.5% of teens reported engaging in sexual activity with casual and main partners respectively. Sixteen percent of teens with main partners and 12% of those with casual partners engaged in receptive anal intercourse (P = 0.31). Condom use is more prevalent for both vaginal (61% vs. 32.4%, P < or = 0.0001) and anal (47.1% vs. 21.3%, P = 0.0428) intercourse in the context of casual as compared to main sexual relationships. Teens involved in a casual relationship were more likely to use anal intercourse as a form of contraception (41.2% vs. 8.5%, P = 0.0022).
It is imperative that health care providers recognize that adolescents engage in anal sex, specifically inquire about their types of sexual behavior and types of sexual relationships so that anticipatory guidance regarding HIV/STI transmission risk reduction education can be tailored to meet their needs.
长期以来，接受肛交一直被视为感染艾滋病毒和性传播感染的风险因素。大多数艾滋病毒/性传播感染预防信息仍在强调阴茎-阴道传播，因此许多青少年并未意识到肛交是危险的性行为。本研究的目的是确定肛交的发生率，并描述城市中有性经验的青少年的性关系类型（主要关系与随意关系）、性行为类型（阴道性交与肛交）以及所使用的避孕方式之间的关系。
从350名年龄在12至18岁之间、在城市健康中心参与一项为期5年的性传播感染感染研究的有性经验的青少年女性中获取生殖健康史。使用频率、百分比和卡方检验对基线性行为数据进行分析和描述。
41%的青少年和86.5%的青少年分别报告与随意性伴侣和主要性伴侣有性行为。有主要性伴侣的青少年中有16%、有随意性伴侣的青少年中有12%进行过接受肛交（P = 0.31）。与主要性关系相比，在随意性关系中，无论是阴道性交（61%对32.4%，P≤0.0001）还是肛交（47.1%对21.3%，P = 0.0428），使用避孕套的情况都更为普遍。处于随意性关系中的青少年更有可能将肛交作为一种避孕方式（41.2%对8.5%，P = 0.0022）。
医疗保健提供者必须认识到青少年会进行肛交，具体询问他们的性行为类型和性关系类型，以便能够根据他们的需求提供关于降低艾滋病毒/性传播感染传播风险教育的前瞻性指导。
