The objectives are to analyse social determinants of sexual health behaviour (condom use and HIV testing) among young, internet-active, cis men who have sex with men (MSM) in a high-income country. The aspects of sexual health behaviour analysed here are condomless anal intercourse with one or more new or casual partner(s), condomless anal intercourse during the most recent sex with a man and HIV testing.
A randomised sample of men active on Sweden's main online community for Lesbian, Gay, Bisexual and Trans people responded to an online survey (response rate 19%). A subsample of young people, aged 15-29, was analysed (effective sample 597-669) using multivariable logistic regression with respect to factors associated with condomless anal intercourse with one or more new or casual partner(s), condomless anal intercourse at most recent sex and not having had a test for HIV.
Low education, being single and living in a metropolitan area were found to be independently associated with condomless anal intercourse with new or casual partner(s). Sex with a steady partner was associated with condomless anal intercourse during the sex. Knowledge of where to get tested, high education, being born outside Sweden and condomless anal intercourse with new or casual sex partner(s) were independently associated with having been tested for HIV.
The factors associated with sexual health behaviour among young MSM are complex, and preventive messages need to be tailored accordingly.
本研究旨在分析高收入国家中，年轻、活跃于互联网、顺性别男同性恋者（MSM）的性健康行为（ condom 使用和 HIV 检测）的社会决定因素。这里分析的性健康行为包括与一个或多个新的或偶然的性伴侣发生无保护的肛交、与男性发生最近一次性行为时无保护的肛交以及 HIV 检测。
随机抽取了活跃于瑞典主要的女同性恋、男同性恋、双性恋和跨性别者在线社区的男性进行在线调查（应答率为 19%）。对其中年龄在 15-29 岁的年轻人亚组进行了多变量逻辑回归分析，以确定与与一个或多个新的或偶然的性伴侣发生无保护的肛交、与男性发生最近一次性行为时无保护的肛交以及未进行 HIV 检测相关的因素。
研究发现，低教育程度、单身和居住在大都市区与与新的或偶然的性伴侣发生无保护的肛交独立相关。与稳定伴侣发生性行为与最近一次性行为时发生无保护的肛交相关。知道在哪里可以进行检测、高教育程度、出生在瑞典以外以及与新的或偶然的性伴侣发生无保护的肛交与 HIV 检测呈独立相关。
年轻 MSM 的性健康行为相关因素复杂，预防信息需要相应地进行定制。
