Young Black gay, bisexual, and other men who have sex with men (YBMSM) are disproportionally affected by HIV. Seroadaptive strategies-modification of sexual behavior based on an individual's perceived serostatus, the perceived status of the partner, and/or HIV transmission risk by the type of sex act-are often used to reduce the risk of HIV transmission or acquisition.
We used demographic, behavioral, and clinical data from Ele[MEN]t, a prospective cohort study of YBMSM aged 18-29 years in Atlanta, GA, conducted during 2015-2019. The prevalence of seroadaptive strategies at baseline was reported, and latent class analysis was used to identify the latent classes of strategies for both YBMSM known and not known to be living with HIV. Latent classes were compared by key behavioral and clinical characteristics to validate our findings.
In a 4-class model, the most common latent class of YBMSM not known to be living with HIV (32.4%) was characterized by all individuals reporting only having sex with men not perceived to be living with HIV. The most common latent class of YBMSM known to be living with HIV (48.2%) was characterized by a combination of serosorting strategies, including using condoms for anal sex with partners not known to be living with HIV and avoiding sex with men not known to be living with HIV.
YBMSM use various patterns of strategies to reduce their HIV transmission or acquisition risk. Our study highlights the need for targeted HIV prevention recommendations based on individual behaviors.
年轻的黑人男同性恋者、双性恋者和其他与男性发生性关系的男性(YBMSM)不成比例地受到艾滋病毒的影响。基于个体的血清状况、伴侣的感知状况以及性行为的艾滋病毒传播风险,血清适应策略(性行为的改变)通常用于降低艾滋病毒传播或感染的风险。
我们使用了 2015 年至 2019 年在佐治亚州亚特兰大市进行的 Ele[MEN]t 前瞻性队列研究中,18-29 岁 YBMSM 的人口统计学、行为和临床数据。报告了基线时血清适应策略的流行率,并使用潜在类别分析来确定已知和未知艾滋病毒感染的 YBMSM 的策略潜在类别。通过关键行为和临床特征比较潜在类别,以验证我们的发现。
在一个 4 类模型中,未被发现携带 HIV 的 YBMSM 的最常见潜在类别(32.4%)的特征是所有个体报告仅与未被发现携带 HIV 的男性发生性行为。已知携带 HIV 的 YBMSM 的最常见潜在类别(48.2%)的特征是采用了一系列血清分类策略,包括与未被发现携带 HIV 的伴侣发生性行为时使用避孕套,避免与未被发现携带 HIV 的男性发生性行为。
YBMSM 使用各种策略来降低他们感染 HIV 的风险。我们的研究强调了需要根据个人行为制定有针对性的 HIV 预防建议。
