In recent years, much attention has been devoted to understanding the HIV risk behaviors of younger men who have sex with men (MSM). Recent data suggest that HIV is becoming an increasing problem for older adults, but little attention has been devoted to understanding their HIV risk behaviors or the factors that underlie their risk taking. This study provides a comparison of these issues among younger and older MSM.
The data come from a subset of younger (ages 18-39, n = 113) and older (ages 50+, n = 109) men participating in a national study of 332 men who use the Internet to find other men for unprotected sex. Men were sampled randomly from 16 websites. Data were collected via telephone interviews conducted in 2008 and 2009.
Younger and older men reported comparable involvement in HIV risk, including involvement in unprotected sex, proportion of sex acts involving internal ejaculation, number of times having anonymous sex, and number of times having multiple-partner sex. Generally speaking, the factors underlying the risk practices of younger and older men were quite different (e.g. self-esteem and condom use self-efficacy for younger men, versus HIV serostatus and depression for older men).
Older MSM using the Internet to find partners for unprotected sex engage in high rates of behaviors that place them at risk for contracting or transmitting HIV. They were just as likely as their younger counterparts to practice these behaviors. The factors "fueling" involvement in risk generally differ for older and younger men, thereby warranting the development of age-specific HIV interventions that can take into account the unique life circumstances and needs of older MSM.
近年来，人们越来越关注了解与男性性行为者（MSM）年龄较小的男性的 HIV 风险行为。最近的数据表明，HIV 对老年人来说是一个日益严重的问题，但人们很少关注了解他们的 HIV 风险行为或导致他们冒险的因素。本研究比较了年轻和年长 MSM 之间的这些问题。
数据来自参加一项全国性研究的年轻（18-39 岁，n=113）和年长（50 岁以上，n=109）男性的一个子样本，这些男性使用互联网寻找其他男性进行无保护的性行为。男性是从 16 个网站中随机抽样的。数据是通过 2008 年和 2009 年进行的电话访谈收集的。
年轻和年长的男性报告了类似的 HIV 风险行为，包括无保护的性行为、涉及内部射精的性行为比例、匿名性行为的次数和多性伴侣性行为的次数。一般来说，年轻和年长男性的风险行为背后的因素有很大的不同（例如，自尊和 condom 使用自我效能感对年轻男性，而 HIV 血清状况和抑郁对年长男性）。
使用互联网寻找无保护性行为伴侣的年长 MSM 从事高风险行为，使他们有感染或传播 HIV 的风险。他们与年轻男性一样，同样有可能从事这些行为。参与风险的因素通常因年龄而异，因此需要制定针对特定年龄的 HIV 干预措施，以考虑到年长 MSM 的独特生活环境和需求。
