This systematic review aims to synthesize articles, abstracts and reports of HIV prevalence studies conducted among men who have sex with men (MSM) and female sex workers (FSW) in Latin America and the Caribbean (LAC).
Authors searched online databases and collected gray literature on HIV prevalence among MSM and FSW from LAC. Year, location, sampling methodology, study design, sample size, HIV prevalence and confidence intervals were abstracted.
A total of 73 studies, dating from 1986 to 2010 were included.The median prevalences for MSM and FSW were 10.6% (interquartile range: 7.4- 17.4) and 2.6% (IQR: 0.6 -4.2), respectively. Variability was high, especially for MSM. The majority of studies recruited participants using convenience methods.
HIV prevalence among MSM was higher than that among FSW. Sampling techniques should be standardized for future studies, prioritizing probability methods.
本系统综述旨在综合分析拉丁美洲和加勒比地区（LAC）男男性行为者（MSM）和女性性工作者（FSW）中 HIV 流行率研究的文章、摘要和报告。
作者检索了在线数据库，并收集了 LAC 地区 MSM 和 FSW 中 HIV 流行率的灰色文献。提取了年份、地点、抽样方法、研究设计、样本量、HIV 流行率和置信区间。
共纳入 73 项研究，时间跨度为 1986 年至 2010 年。MSM 和 FSW 的中位流行率分别为 10.6%（四分位间距：7.4-17.4）和 2.6%（IQR：0.6-4.2）。变异性很高，尤其是 MSM。大多数研究都使用方便的方法招募参与者。
MSM 中的 HIV 流行率高于 FSW。未来的研究应标准化抽样技术，优先使用概率方法。
