Women in prison have a higher prevalence of HIV than men. After release from prison, former inmates have the opportunity to engage in risk behaviors for HIV and other sexually transmitted infections (STIs). We sought to assess change in risk behaviors over time and the association of gender with risk behavior in the postrelease period. In this prospective cohort study, we interviewed 200 former inmates (51 women) approximately two weeks (baseline) and three months (follow-up) after release and tested them for HIV infection at follow-up. We examined the association of gender with unprotected vaginal or anal sex in the last seven days using chi-square and Fisher's exact tests and multivariable logistic regression. At baseline, 22% of men and 41% of women reported unprotected vaginal sex (p < 0.01) and 5% of men and 8% of women reported unprotected anal sex (p = 0.51). Being younger (OR for each decade increase 0.48, 95% CI = 0.29-0.80), being gay/lesbian or being bisexual (compared with being heterosexual, OR = 4.74, 95% CI = 1.01-22.17 and OR = 3.98, 95% CI = 1.41-11.26, respectively), or reporting a drug of choice of heroin/speedballs or cocaine/crack (compared with marijuana/no drug of choice, OR = 24.00, 95% CI = 5.15-111.81 and OR = 3.49, 95% CI = 1.20-10.18, respectively) was associated with unprotected vaginal or anal sex after adjusting for race, homelessness, and hazardous drinking. At follow-up, 21% of men and 44% of women reported unprotected sex (p = 0.005), and female gender (OR = 4.42, 95% CI = 1.79-10.94) and hazardous drinking (compared with not meeting criteria for hazardous drinking, OR = 3.64, 95% CI = 1.34-9.86) were associated with unprotected sex, adjusting for race and homelessness. In this population with a high prevalence of HIV, we demonstrated persistent engagement in sexual risk behavior during the postrelease period. Enhanced efforts to promote sexual health and reduced risk behavior among both male and female current and former prison inmates are needed, including improved access to preventive care and HIV and STI screening, testing, and treatment.
监狱中的女性感染艾滋病毒的比例高于男性。刑满释放后,曾经的囚犯有机会从事感染艾滋病毒及其他性传播感染的风险行为。我们试图评估风险行为随时间的变化以及性别与释放后风险行为之间的关联。在这项前瞻性队列研究中,我们在释放后约两周(基线)和三个月(随访)对200名曾经的囚犯(51名女性)进行了访谈,并在随访时对他们进行了艾滋病毒感染检测。我们使用卡方检验、费舍尔精确检验和多变量逻辑回归分析了性别与过去七天内无保护阴道或肛交之间的关联。在基线时,22%的男性和41%的女性报告有无保护阴道性交(p<0.01),5%的男性和8%的女性报告有无保护肛交(p = 0.51)。在调整种族、无家可归状况和有害饮酒因素后,年龄较小(每增加十岁,比值比为0.48,95%置信区间 = 0.29 - 0.80)、同性恋或双性恋(与异性恋相比,比值比分别为4.74,95%置信区间 = 1.01 - 22.17和3.98,95%置信区间 = 1.41 - 11.26),或报告首选毒品为海洛因/速球或可卡因/快克(与大麻/无首选毒品相比,比值比分别为24.00,95%置信区间 = 5.15 - 111.81和3.49,95%置信区间 = 1.20 - 10.18)与无保护阴道或肛交有关。在随访时,21%的男性和44%的女性报告有无保护性行为(p = 0.005),在调整种族和无家可归状况后,女性性别(比值比 = 4.42,95%置信区间 = 1.79 - 10.94)和有害饮酒(与不符合有害饮酒标准相比,比值比 = 3.64,95%置信区间 = 1.34 - 9.86)与无保护性行为有关。在这个艾滋病毒感染率很高的人群中,我们证明了释放后期间持续存在性风险行为。需要加大力度促进男性和女性在押及曾经的囚犯的性健康并减少风险行为,包括改善获得预防性护理以及艾滋病毒和性传播感染筛查、检测及治疗的机会。
