Adolescent sexual activity involving three or more people is an emerging public health concern. The goal of this exploratory, cross-sectional study was to describe the prevalence, correlates, and context of multiple-person sex among a sample of adolescent females seeking health care from an urban clinic. Because sex involving multiple people may either be consensual (i.e., "three-ways" or "group sex") or forced (i.e., "gang rape"), we use the term "multi-person sex" (MPS) to encompass these experiences. Subjects were 328 females, ages 14-20 years old, who utilized a Boston-area community- or school-based health clinic between April and December of 2006, and completed an anonymous survey using computer-assisted self-interview software. Overall, 7.3% reported ever having had a MPS experience. Of these, 52% reported ever being pressured to engage in MPS and 43% reported ever being threatened or forced. Condom nonuse by at least one male participant in the most recent MPS was reported by 45%. Controlling for potential demographic confounders, MPS was associated with cigarette smoking (adjusted prevalence ratio [APR], 3.83; 95% confidence interval [CI], 1.56-9.44), sexual initiation prior to age 15 (APR, 2.50; 95% CI, 1.04-5.98), ever being diagnosed with an STI (APR, 2.55; 95% CI, 1.08-6.03), dating violence victimization (APR, 4.43; 95% CI, 1.68-11.69), childhood sexual abuse victimization (APR, 4.30; 95% CI, 1.83-10.07) and past-month pornography exposure (APR, 4.79; 95% CI, 1.91-11.98). Additional study of the perpetration and prevention of adolescent MPS is urgently needed.
涉及三人或三人以上的青少年性行为是一个新出现的公共卫生问题。本探索性、横断面研究的目的是描述在一个从城市诊所寻求医疗保健的青少年女性样本中，多人性经历的流行率、相关因素和背景。由于涉及多人的性行为可能是双方自愿的（即“三人行”或“群交”），也可能是被迫的（即“轮奸”），我们使用“多人性经历”（MPS）来涵盖这些经历。研究对象为 328 名年龄在 14 至 20 岁之间的女性，她们于 2006 年 4 月至 12 月期间在波士顿地区的社区或学校诊所使用计算机辅助自我访谈软件完成了匿名调查。总体而言，有 7.3%的人报告曾有过 MPS 经历。其中，52%的人报告曾被迫发生 MPS，43%的人报告曾受到威胁或强迫。在最近的 MPS 中，至少有一名男性参与者未使用安全套的情况占 45%。在控制了潜在的人口统计学混杂因素后，MPS 与吸烟（调整后的流行率比 [APR]，3.83；95%置信区间 [CI]，1.56-9.44）、15 岁前首次发生性行为（APR，2.50；95% CI，1.04-5.98）、曾被诊断患有性传播感染（APR，2.55；95% CI，1.08-6.03）、约会暴力受害（APR，4.43；95% CI，1.68-11.69）、儿童期性虐待受害（APR，4.30；95% CI，1.83-10.07）和过去一个月接触色情内容（APR，4.79；95% CI，1.91-11.98）有关。迫切需要进一步研究青少年 MPS 的实施和预防。
