PROJECT ABSTRACT: HIV disparity persist among Latino men who have sex with men (MSM), especially those who are immigrants. The CDC estimates the lifetime HIV risk is 1 in 5 for Latino MSM compared to 1 in 11 for white MSM. Pre-Exposure Prophylaxis (PrEP) is a biomedical strategy highly effective in preventing HIV acquisition, with the potential to reduce the number of new HIV infections among Latino MSM in the U.S. PrEP involves once daily dosing of medications. The FDA has approved two medications, sold under the brand names Truvada® and Descovy® for daily use as PrEP. The Centers for Disease Control and Prevention (CDC) has established clinical guidelines for administering PrEP to high-risk candidates. While evidence indicates that PrEP use is rising in the U.S., disparities persist in uptake among Latino MSM, despite their reported high levels of interest in using PrEP. To address this disparity, we propose a 2-phase project to develop a pilot PrEP intervention called Estoy PrEParado (I'm PrEPared) to facilitate initiation and adherence to PrEP among immigrant Latino MSM. The project will develop an engaging, culturally tailored intervention using the Information-Motivation-Behavioral Skills (IMB) model. The specific aims of the project are: Aim 1: based on data from a prior study, the project will elicit feedback, validation and modification to the initial content areas of the Estoy PrEParado intervention to facilitate PrEP adoption and adherence among immigrant Latino MSM; and Aim 2: the project will conduct a small randomized pilot of Estoy PrEParado to assess the feasibility, acceptability and preliminary impact of the intervention in moving immigrant Latino MSM along the PrEP cascade to initiation. In formative phase 1, the project will use the innovative and novel World Café approach to facilitate a community conversation with immigrant LMSM (n≈40) to validate, modify and refine the initial intervention content areas of the Estoy PrEParado pilot intervention. The World Café is a powerful conversational process for facilitating constructive group dialogue that produces ideas and knowledge that can be put into practice. The project will also elicit feedback and input on the contents of the intervention from a project-specific Intervention Advisory Committee (IAC) comprised of academic and community experts. In phase 2, the project will conduct a small randomized pilot of 80 participants (40 participants receiving the PrEP intervention and 40 participants receiving standard care, i.e., PrEP referrals) to establish feasibility, acceptability and preliminary impact. If the intervention shows promise, the findings will support the preparation of a larger scale R01 efficacy trial.

项目摘要：艾滋病毒差异在拉丁裔男男性行为者 (MSM) 中持续存在，尤其是 CDC 估计拉丁裔男男性接触者终生感染艾滋病毒的风险为五分之一，而这一比例为五分之一。 11 白人 MSM 暴露前预防 (PrEP) 是一种非常有效预防 HIV 的生物医学策略。 获得，有可能减少美国拉丁裔 MSM 中新发 HIV 感染的数量。 FDA 已批准了两种以该品牌销售的药物。 疾病控制和预防中心将日常使用的 Truvada® 和 Descovy® 命名为 PrEP。 (CDC) 已制定了针对高风险候选人实施 PrEP 的临床指南。 表明 PrEP 在美国的使用正在增加，拉丁裔 MSM 的使用率仍然存在差异，尽管他们 据报道，人们对使用 PrEP 非常感兴趣。为了解决这一差异，我们提出了一个分两阶段的项目。 开发名为 Estoy PrEParado（我是 PrEPared）的试点 PrEP 干预措施，以促进启动和坚持 该项目将开发一种有吸引力的、针对文化的干预措施。 使用信息-动机-行为技能 (IMB) 模型 该项目的具体目标是： 目标 1： 根据先前研究的数据，该项目将征求反馈、验证和修改初始方案 Estoy PrEParado 干预措施的内容领域，旨在促进移民采用和遵守 PrEP 拉丁裔 MSM；目标 2：该项目将进行 Estoy PrEParado 的小型随机试点，以评估 移民拉丁裔男男性接触者沿途的可行性、可接受性和初步影响 在 PrEP 级联启动阶段，该项目将使用创新的 World Café。 促进与移民 LMSM (n≈40) 进行社区对话的方法，以验证、修改和完善 Estoy PrEParado 试点干预的初始干预内容领域是一个强大的干预措施。 促进建设性小组对话的对话过程，产生可以 该项目还将征求有关干预内容的反馈和意见。 特定项目的干预咨询委员会（IAC）由学术和社区专家组成。 第 2 阶段，该项目将进行一项由 80 名参与者组成的小型随机试点（40 名参与者接受 PrEP） 干预和 40 名接受标准护理的参与者，即 PrEP 转诊）以确定可行性， 如果干预措施显示出希望，调查结果将支持准备工作。 更大规模的 R01 功效试验。
