“血清适应”包括在了解自己和性伴侣血清状况的基础上，为减少艾滋病毒感染和传播风险而采取的性行为。我们测量了通过时间-地点抽样（TLS）招募的男男性行为（MSM）中血清适应性行为的患病率，从三个角度：个人（N= 1，207 MSM），性二人组（N= 3，746伴侣）和过去六个月的性事件（N= 63，789事件）。当考虑到个体的一致行为模式时，血清适应性比100%安全套使用更常见（分别为39.1%和25.0%的男性）。在性二人组中，100%使用安全套比血清适应更常见（分别为33.1%和26.4%）。考虑到性行为的发生，不肛交（65.0%）和使用安全套（16.0%）是最常见的降低风险的行为。获得和传播风险最高的性行为（与艾滋病毒血清不一致或身份不明的伴侣处于风险较高的位置进行无保护的肛交）仅发生在1.6%的性行为中。总的来说，MSM通过多种策略实现了高水平的性伤害减少。需要对血清适应性行为进行详细的衡量，以有效地针对艾滋病毒风险，并衡量血清分类和相关的减少艾滋病毒流行性伤害战略的潜力。
“Seroadaptation” comprises sexual behaviors to reduce the risk of HIV acquisition and transmission based on knowing one’s own and one’s sexual partners’ serostatus. We measured the prevalence of seroadaptive behaviors among men who have sex with men (MSM) recruited through time-location sampling (TLS) across three perspectives: by individuals (N=1,207 MSM), among sexual dyads (N=3,746 partnerships), and for sexual episodes (N=63,789 episodes) in the preceding six months. Seroadaptation was more common than 100% condom use when considering the consistent behavioral pattern of individuals (adopted by 39.1% vs. 25.0% of men, respectively). Among sexual dyads 100% condom use was more common than seroadaptation (33.1% vs. 26.4%, respectively). Considering episodes of sex, not having anal intercourse (65.0%) and condom use (16.0%) were the most common risk reduction behaviors. Sex of highest acquisition and transmission risks (unprotected anal intercourse with a HIV serodiscordant or unknown status partner in the riskier position) occurred in only 1.6% of sexual episodes. In aggregate, MSM achieve a high level of sexual harm reduction through multiple strategies. Detailed measures of seroadaptive behaviors are needed to effectively target HIV risk and gauge the potential of serosorting and related sexual harm reduction strategies on the HIV epidemic.
