This cross-sectional study analyzed social vulnerability, individual, and programmatic factors associated with low knowledge on HIV/AIDS among men who have sex with men (MSM). Respondent Driven Sampling (RDS) was used in 10 Brazilian cities. Knowledge scores on HIV/AIDS were estimated by Item Response Theory and categorized in three levels: high, medium, and low knowledge. Ordinal logistic regression was used for the analysis. Of the 3,746 MSM, 36.6%, 37.4%, and 26% showed high, medium, and low knowledge, respectively. The following were associated with low knowledge in the final model: schooling ≤ 8 years, non-white skin color, economic classes C and D-E, age < 25 years, having only one sex partner, and no previous HIV test. It is essential to improve knowledge on HIV/AIDS among young MSM with low socioeconomic status. Interventions focused on programmatic vulnerability factors can help reduce individual and social risk.
这项横断面研究分析了与男男性行为者（MSM）中艾滋病病毒/艾滋病知识水平较低相关的社会脆弱性、个体因素和项目因素。在巴西的10个城市采用了应答者驱动抽样（RDS）方法。通过项目反应理论估计艾滋病病毒/艾滋病的知识得分，并分为三个水平：高、中、低知识水平。采用有序逻辑回归进行分析。在3746名男男性行为者中，分别有36.6%、37.4%和26%表现出高、中、低知识水平。最终模型中与低知识水平相关的因素如下：受教育年限≤8年、非白人肤色、C和D-E经济阶层、年龄<25岁、只有一个性伴侣以及以前未进行过艾滋病病毒检测。提高社会经济地位较低的年轻男男性行为者对艾滋病病毒/艾滋病的认识至关重要。针对项目脆弱性因素的干预措施有助于降低个体和社会风险。
