We examined HIV prevalence and the socioeconomic correlates of HIV infection, sexual risk behaviors, and substance use among Latino gay and bisexual men and transgender persons in Chicago and San Francisco.
Data were collected from a sample of 643 individuals (Chicago: n=320; San Francisco: n=323) through respondent-driven sampling and computer-assisted self-administered interviews.
HIV prevalence in San Francisco (0.325; 95% confidence interval [CI]=0.260, 0.393) was higher than in Chicago (0.112; 95% CI=0.079, 0.163). In San Francisco, HIV prevalence was higher among US-born residents than among those born outside the country; in Chicago, the opposite was true. Heavy use of alcohol was prevalent, especially in Chicago (0.368; 95% CI=0.309, 0.432; San Francisco: 0.154; 95% CI=0.116, 0.192). Drug use and more education were positively correlated and greater age was negatively correlated with unprotected anal intercourse.
Heavy alcohol drinking and use of drugs remain a significant public health problem in this population. Drug use was more closely linked to HIV sexual risk behaviors than was heavy drinking.
我们调查了芝加哥和旧金山的拉丁裔男同性恋者、双性恋男性及跨性别者中的艾滋病毒流行情况，以及艾滋病毒感染、性风险行为和物质使用的社会经济相关因素。
通过应答驱动抽样和计算机辅助自我管理访谈，从643名个体样本（芝加哥：n = 320；旧金山：n = 323）中收集数据。
旧金山的艾滋病毒流行率（0.325；95%置信区间[CI] = 0.260, 0.393）高于芝加哥（0.112；95% CI = 0.079, 0.163）。在旧金山，美国出生的居民中的艾滋病毒流行率高于国外出生的居民；在芝加哥则相反。大量饮酒的情况普遍存在，尤其是在芝加哥（0.368；95% CI = 0.309, 0.432；旧金山：0.154；95% CI = 0.116, 0.192）。吸毒与受教育程度较高呈正相关，年龄较大与无保护肛交呈负相关。
大量饮酒和吸毒在这一人群中仍然是一个重大的公共卫生问题。吸毒比大量饮酒与艾滋病毒性风险行为的联系更为紧密。
