CENTRAL AMERICA (2012): Study Evaluating the Com-Prevention Program with Men at Risk in GUATEMALA, EL SALVADOR, NICARAGUA, COSTA RICA, PANAMÁ Y BELICE. Round 1

The goal of this study is to collect baseline data on the prevalence of condom use and the opportunity, ability and motivation to adopt healthier behaviors among Men at Risk in Central America, defined as: migrant workers, uniformed men (private forces), truckers, construction workers, bus drivers and fishermen, all of them potential clients of sex workers. This study design is the first wave of TRaCs with Men At Risk. It pretends to respond to three fundamental questions. Monitoring: What are the levels in key behavioral indicators (condom use at last sex and consistent condom use) among Men at Risk? Segmentation: Which opportunity, ability and motivation constructs are significantly associated to safer behavior (condom use at last sex and consistent condom use)? Evaluation: what is the level of exposure to the Com-Prevention Program: % of Men at Risk going through at least 3 interpersonal communication activities (IPC), one biomedical component (HIV-STI’s test and treatment if necessary), and one complim entary component (attendance to Family Planning Services and/or Alcohol/Drug Treatment Center)? Is the exposure to such program associated to healthier behaviors?

本研究旨在收集中美洲高危男性人群（Men at Risk）中避孕套使用普及率，以及其采纳更健康行为的机会、能力与动机的基线数据。本研究定义的高危男性人群包括：务工移民、制服人员（私人安保力量）、卡车司机、建筑工人、巴士驾驶员及渔民，上述人群均为性工作者的潜在服务对象。
本研究为高危男性TRaC队列（TRaC）的首轮随访波次，旨在回应三个核心研究问题：
1. 监测问题：高危男性人群的关键行为指标（末次性行为时的避孕套使用情况、持续避孕套使用情况）处于何种水平？
2. 分类分析问题：哪些与机会、能力及动机相关的构念，与安全性行为（末次性行为时的避孕套使用情况、持续避孕套使用情况）存在显著关联？
3. 评估问题：高危男性人群接触Com-Prevention预防项目（Com-Prevention Program）的程度如何？具体指标为：完成至少3次人际沟通活动（Interpersonal Communication, IPC）、接受1项生物医学干预内容（必要时开展HIV/性传播感染（Sexually Transmitted Infections, STI）检测与治疗）、以及参与1项补充性服务项目（参与计划生育服务及/或酒精/药物依赖治疗中心服务）的人群占比。此外，接触该预防项目是否与更健康的行为存在关联？
