We sought to define Chlamydia trachomatis positivity among women who report sexual activity with women, a population for which sparse data on this infection are available and for whom health disparities including challenged access to comprehensive sexual and reproductive health services, have been reported.
We analyzed data from 9358 family planning clinic visits with C trachomatis tests among women aged 15 to 24 years who reported sexual activity within the past year exclusively with women (WSW) or with men and women (WSMW), in the Region X Infertility Prevention Project. Characteristics were compared with women who reported sexual activity exclusively with men (WSM). Results. C trachomatis positivity among both WSW and WSMW was 7.1%, compared with 5.3% among WSM. Behavioral risks were more commonly reported by WSW and WSMW, compared with reports by WSM. Risks for C trachomatis positivity were comparable across groups and included younger age, non-White race, behavioral risks, and clinical signs.
Higher C trachomatis positivity among women reporting same-sex sexual behavior supports investigation into potential explanatory factors, including sexual behaviors, biological susceptibility, routine C trachomatis screening disparities, sexual identity disclosure, and sexual network assessment.
我们旨在定义报告与女性发生性行为的女性中沙眼衣原体（Chlamydia trachomatis）阳性率，该人群对此感染的相关数据较少，据报道，包括全面性与生殖健康服务获取受限在内的健康差异在该人群中较为突出。
我们分析了 X 区域不孕预防项目中 9358 名年龄在 15 至 24 岁之间、过去一年中仅与女性（WSW）或男性和女性（WSMW）发生性行为的计划生育诊所就诊者的沙眼衣原体检测数据。将这些特征与仅与男性（WSM）发生性行为的女性进行比较。结果：与仅与男性发生性行为的女性相比，WSW 和 WSMW 中沙眼衣原体阳性率分别为 7.1%和 7.1%，而 WSM 为 5.3%。与仅与男性发生性行为的女性相比，WSW 和 WSMW 更常报告行为风险。各群体的沙眼衣原体阳性风险相当，包括年龄较小、非白人种族、行为风险和临床体征。
报告同性性行为的女性中沙眼衣原体阳性率较高，这支持对潜在解释因素进行调查，包括性行为、生物学易感性、常规沙眼衣原体筛查差异、性身份披露和性网络评估。
