We sought to examine behavioral risks and behavior changes associated with testing HIV-positive among sexually transmitted infection (STI) patients, in order to inform HIV- and STI-prevention interventions.
We performed a cohort study of 29 STI patients who seroconverted from HIV-negative to HIV-positive during 1 year of observation and 77 STI patients who persistently tested HIV-negative. Computerized behavioral interviews were collected at baseline and at 1 year, and STI clinic charts were abstracted over the same 1-year period.
The STI patients who reported genital bleeding during sexual activity at baseline were significantly more likely to test HIV-positive. Reductions in number of sexual partners and rates of unprotected intercourse occurred for all STI clinic patients regardless of whether they tested HIV-positive.
Although risk reductions occurred, 5% of HIV-negative STI clinic patients subsequently tested HIV-positive over 1 year. Behavioral risk-reduction interventions are urgently needed for male and female STI clinic patients.
我们旨在研究性传播感染（STI）患者 HIV 阳性检测相关的行为风险和行为变化，以便为 HIV 和 STI 预防干预措施提供信息。
我们对 29 名在观察期内从 HIV 阴性转为 HIV 阳性的 STI 患者和 77 名持续 HIV 阴性的 STI 患者进行了队列研究。在基线和 1 年时进行了计算机化行为访谈，并在同一 1 年内从 STI 诊所图表中提取数据。
在基线时报告性行为中出现生殖器出血的 STI 患者检测 HIV 阳性的可能性显著更高。所有 STI 诊所患者无论 HIV 检测结果如何，性伴侣数量和无保护性行为的比例都有所减少。
尽管风险降低，但在 1 年内仍有 5%的 HIV 阴性 STI 诊所患者 HIV 检测呈阳性。迫切需要为男女性 STI 诊所患者提供行为风险降低干预措施。
