To examine demographic and behavioral characteristics in incarcerated women to determine which characteristics are associated with prevalent sexually transmitted infections (STIs).
A cross-sectional analysis of data of 205 women entering jail in Rhode Island was performed as part of a study evaluating a family planning program. Women were recruited near time of commitment, and inclusion was limited to women at risk for an unplanned pregnancy. Incarcerated women were interviewed by a research assistant for demographic information, psychosocial and behavioral characteristics. Self-collected vaginal swabs were tested for STIs, including Neisseria gonorrhoeae and Chlamydia trachomatis by polymerase chain reaction and Trichomonas vaginalis by InPouch culture. Relative risks (RRs) were estimated using Poisson regression.
Sixty-eight of 205 patients tested positive for an STI [33%; 95% confidence interval (CI) 27-40%]. Forty-five patients (26%) tested positive for T. vaginalis, 27 (14%) were positive for C. trachomatis, and 21 (11%) were positive for N. gonorrhoeae. On bivariate analysis, 6 or more sexual partners in the last year (RR 1.84; 95% CI 1.01-3.36), exchanging sex for drugs/money (RR 1.65; 95% CI 1.01-2.69), and homelessness (RR 1.82; 95% CI 1.07-3.09) were associated with STI. After adjustment for age, race/ethnicity, education, and other covariates, none of the factors was significantly associated with STI.
The prevalence of STI in this jail population is high. Incarceration represents a unique opportunity to evaluate and treat this underserved population. Predictors of infection are limited and infection is common; therefore, routine screening should be considered in this population.
研究被监禁女性的人口统计学和行为特征，以确定哪些特征与性传播感染（STIs）的流行有关。
作为一项评估计划生育项目研究的一部分，对罗德岛205名入狱女性的数据进行了横断面分析。女性在入狱时被招募，纳入对象仅限于有意外怀孕风险的女性。由一名研究助理对被监禁女性进行访谈，获取人口统计学信息、心理社会和行为特征。自行采集的阴道拭子进行STIs检测，包括通过聚合酶链反应检测淋病奈瑟菌和沙眼衣原体，通过InPouch培养检测阴道毛滴虫。使用泊松回归估计相对风险（RRs）。
205名患者中有68名STIs检测呈阳性[33%；95%置信区间（CI）27 - 40%]。45名患者（26%）阴道毛滴虫检测呈阳性，27名（14%）沙眼衣原体检测呈阳性，21名（11%）淋病奈瑟菌检测呈阳性。在双变量分析中，过去一年有6个或更多性伴侣（RR 1.84；95% CI 1.01 - 3.36）、以性换毒品/金钱（RR 1.65；95% CI 1.01 - 2.69）和无家可归（RR 1.82；95% CI 1.07 - 3.09）与STIs有关。在对年龄、种族/民族、教育程度和其他协变量进行调整后，这些因素均与STIs无显著关联。
该监狱人群中STIs的患病率很高。监禁为评估和治疗这一服务不足的人群提供了独特的机会。感染的预测因素有限且感染很常见；因此，应考虑对该人群进行常规筛查。
