To assess the relative risk for AIDS between men who have sex with other men and heterosexual men.
Estimates on the proportion of men who have sex with men in Brazil and AIDS data from Brazil's Information System for Notifiable Diseases, were utilized. Estimates were calculated for the relative risk (RR) for AIDS of men who have sex with men with respect to heterosexual masculine population in Brazil; state and city of São Paulo; and state and city of Rio de Janeiro, from 1996 to 2003. The trajectory of the RR in this period was also analyzed.
The estimates for relative risk decreased, with a tendency to stabilize: from 34.3 to 19.3 in the entire country and from 32.1 and 6.3 in the locations analyzed. In the country in 2003, the relative risk of bisexual men in relation to heterosexual men was 16.0. The RR for exclusive homosexuals had a decreasing trajectory in all of the locations studied, but not for the bisexual population.
In all locations, the relative risk for men who have sex with other men was higher in relation to heterosexual men. This result indicates a high and persistent vulnerability among this population.
评估男男性行为者与异性恋男性之间患艾滋病的相对风险。
利用巴西男男性行为者比例的估计数据以及巴西法定传染病信息系统的艾滋病数据。计算了1996年至2003年期间巴西、圣保罗州和市、里约热内卢州和市男男性行为者相对于异性恋男性人群患艾滋病的相对风险（RR）。还分析了这一时期RR的变化轨迹。
相对风险估计值下降，并有稳定趋势：在全国范围内从34.3降至19.3，在分析的地区从32.1降至6.3。2003年在该国，双性恋男性相对于异性恋男性的相对风险为16.0。在所有研究地点，纯同性恋者的RR呈下降趋势，但双性恋人群并非如此。
在所有地区，男男性行为者相对于异性恋男性的相对风险更高。这一结果表明该人群存在高度且持续的易感性。
