Mobile phone technology may help sustain reductions in HIV/STI transmission risk behaviors among female sex workers (FSWs). We examined the efficacy of a text messaging intervention designed to maintain behavioral improvements in safer sex practices among 602 FSWs in Tijuana and Ciudad Juarez, Mexico. We hypothesized that FSWs who received brief risk reduction counseling and theory-based safer sex maintenance text messages over a 24-month period would have fewer incident HIV/STIs and report greater maintenance of safer sex practices compared to FSWs who received counseling and texts on maintaining general health. Theory-based texts did not change the odds of becoming infected with HIV/STIs in either study site. However, they did lead to significant, sustained protected sex in Tijuana. Theory-based text messaging interventions may help sustain reductions in sexual risk behavior among FSWs.Trial Registration Clinical Trials.gov. Identifier: NCT02447484.
手机技术可能有助于维持女性性工作者（FSW）中 HIV/性传播感染（STI）传播风险行为的减少。我们研究了一项短信干预措施的效果，该措施旨在维持墨西哥蒂华纳和华雷斯城的 602 名 FSW 中更安全的性行为实践的改善。我们假设，在 24 个月的时间内，接受简短的减少风险咨询和基于理论的更安全的性行为维持短信的 FSW 与接受有关维持一般健康的咨询和短信的 FSW 相比，HIV/STI 的发生率较低，并且报告了更大的安全性行为维持。基于理论的短信并没有改变两个研究地点感染 HIV/STI 的几率。然而，它们确实导致了蒂华纳显著且持续的安全性行为。基于理论的短信干预措施可能有助于维持 FSW 中降低性风险行为。
