项目摘要 性传播感染仍然是影响数百万人的一个主要公共卫生问题， 世界各地的人们。性和性别少数群体，包括男男性行为者， 跨性别妇女，承担着很高的性传播感染负担，同时报告风险因素，经济 边缘化、社会排斥和污名化，阻碍了他们获得预防和 性传播感染的治疗选择哥伦比亚关于性传播感染流行率的资料很少 或与获得和传播性传播感染有关的风险因素。目前的建议包括： 使用受访者驱动抽样招募一组变性妇女和男男性行为者进行性传播感染检测 和风险评估，在这些往往很难接触到的人群。本项目将使用RDS获取数据， 评估MSM和其他SGM中未满足的性传播感染预防、诊断和治疗需求 人口。它还将促进跨性别妇女参加我们的U-19梅毒项目。的 我们研究的中心总体假设是，在男男性接触者和变性女性中， 在哥伦比亚的卡利，梅毒、淋病、衣原体、 HPV和病毒性肝炎。为了验证我们的假设，我们建议使用受访者驱动抽样， 估计哥伦比亚卡利男男性行为者和与男性发生性关系的变性妇女的性传播感染患病率。 此外，我们还将量化这些人的性健康、知识、态度和做法的指标。 人口。我们的论点是，这种方法将掩盖隐藏的负担和未得到满足的性需求， 这些人群的健康需求，并将允许政策制定者，卫生保健提供者和当地 社区通过干预计划采取行动。

PROJECT SUMMARY Sexually transmitted infections (STIs) continue to be a major public health problem afflicting millions of people worldwide. Sexual and gender minorities (SGM), including men who have sex with men (MSM) and transgender women, bear a high burden of STIs, while reporting higher rates of risk factors, economic marginalization, social exclusion, and stigmatization which hinders their access to preventive and therapeutic options for STIs. Little information is available in Colombia regarding the prevalence of STIs in SGMs or the risk factors linked to acquiring and transmitting STIs. The current proposal incorporates the use of Respondent Driven Sampling to recruit a group of transgender women and MSM for STI testing and risk assessment in these often hard to reach populations. This project will use RDS to obtain data to assess the unmet need for prevention, diagnosis, and treatment of STIs in MSM and other SGM populations. It will also facilitate enrollment of transgender women into our U-19 syphilis project. The central overarching hypothesis of our study is that in MSM and transgender women who have sex with other men in Cali, Colombia there is a high, unrecognized prevalence of syphilis, gonorrhea, chlamydia, HPV, and viral hepatitis. To test our hypothesis, we propose to use Respondent Driven Sampling to estimate the prevalence of STIs in MSM and transgender women who have sex with men, in Cali, Colombia. In addition, we will quantify metrics of sexual health, knowledge, attitudes and practices of these populations. It is our contention that this approach will undercover the hidden burden and unmet sexual health needs of these populations and will allow policy makers, health care providers and the local community to act upon this information through intervention planning.
