To estimate HIV and sexually transmitted disease (STD) prevalence and behavioral risk characteristics of men who have sex with men (MSM) in Chennai, India.
A cross-sectional population-based random sample survey was conducted in 2001. Randomly selected residents of 30 slums in Chennai were interviewed for behavioral risk factors through face-to-face interviews. Sera and urine were examined for syphilis, HIV-1, gonorrhea, and chlamydia. Logistic regression analyses were used to assess associations between MSM status and HIV infection and to identify risk characteristics of MSM.
Of 774 men, 46 reported (5.9%) sex with other men. MSM were more likely to be seropositive for HIV (odds ratio [OR] = 8.57; 95% confidence interval [CI]: 1.83, 40.23) and were more likely to have a history of STD (OR = 2.66; 95% CI: 1.18, 6.02) than non-MSM. Men who used illicit drugs in past 3 months (adjusted odds ratio [AOR] = 4.01; 95% CI: 1.92, 8.41), ever exchanged money for sex (AOR = 3.93; 95% CI: 1.97, 7.84), or were ever tested for HIV (AOR = 3.72; 95% CI: 1.34, 10.34) were significantly more likely to report sex with men.
MSM in Chennai slums are at high risk for HIV. HIV prevention strategies aimed at changing unsafe drug and sexual practices should target the general population of men, with specific attention to areas with high rates of MSM.
评估印度钦奈男男性行为者（MSM）中艾滋病毒（HIV）和性传播疾病（STD）的流行情况以及行为风险特征。
2001年开展了一项基于人群的横断面随机抽样调查。通过面对面访谈，对钦奈30个贫民窟中随机选取的居民进行行为风险因素调查。检测血清和尿液中的梅毒、HIV-1、淋病和衣原体。采用逻辑回归分析评估MSM状态与HIV感染之间的关联，并确定MSM的风险特征。
在774名男性中，46人报告（5.9%）与其他男性发生过性行为。与非MSM相比，MSM感染HIV的血清学阳性可能性更高（优势比[OR]=8.57；95%置信区间[CI]：1.83，40.23），且有性传播疾病史的可能性更大（OR=2.66；95%CI：1.18，6.02）。在过去3个月内使用过非法药物的男性（调整后优势比[AOR]=4.01；95%CI：1.92，8.41）、曾以钱换性的男性（AOR=3.93；95%CI：1.97，7.84）或曾接受过HIV检测的男性（AOR=3.72；95%CI：1.34，10.34）报告与男性发生性行为的可能性显著更高。
钦奈贫民窟中的MSM感染HIV风险很高。旨在改变不安全药物和性行为的HIV预防策略应针对男性普通人群，尤其要关注MSM比例高的地区。
