The proportion of newly diagnosed HIV and STI cases among men who have sex with men (MSM) that were contracted abroad has been increasing in Sweden. The present study explored factors associated with casual unprotected anal intercourse (UAI) and travelling abroad among MSM.
A cross-sectional stratified survey with 2751 MSM was conducted. The frequency of sexual practices among men who had casual UAI abroad (<12 months) with that of men who had casual UAI only in Sweden were compared and factors associated with casual UAI abroad were identified through regression analysis.
Factors associated with casual UAI abroad within the previous 12 months were: visit a gay sauna (OR 6.15, 95% CI 3.43-11.06), visit gay café/bar/pub (OR 3.24, 95% CI 1.62-6.48), experience of UAI with a foreign visitor (OR 4.80, 95% CI 2.37-9.75), living with HIV (OR 2.73, 95% CI 1.15-6.48), reporting poor overall health (OR 2.24, 95% CI 1.13-4.44), being born outside Sweden (OR 2.21, 95% CI 1.08-4.53), and being vaccinated against hepatitis A, hepatitis B, or both (OR 1.92, 95% CI 1.13-3.27).
MSM who engage in casual UAI abroad need to increase their understanding of related risks and that risk varies with place and practice. Health care professionals should address the preventive needs of traveling MSM and offer counselling and STI-preventive measures.
在瑞典，新诊断出的 HIV 和性传播感染（STI）病例中，有一部分是男男性行为者（MSM）在国外感染的。本研究旨在探讨与 MSM 偶然无保护肛交（UAI）和出国旅行相关的因素。
采用横断面分层调查的方法，对 2751 名 MSM 进行了研究。比较了在国外有过偶然 UAI（<12 个月）的男性与仅在瑞典有过偶然 UAI 的男性之间的性行为频率，并通过回归分析确定了与在国外偶然 UAI 相关的因素。
在过去 12 个月内，与在国外偶然 UAI 相关的因素有：去男同性恋桑拿浴室（OR 6.15，95%CI 3.43-11.06）、去男同性恋咖啡馆/酒吧/酒馆（OR 3.24，95%CI 1.62-6.48）、与外国来访者发生 UAI 的经历（OR 4.80，95%CI 2.37-9.75）、HIV 感染（OR 2.73，95%CI 1.15-6.48）、自述总体健康状况不佳（OR 2.24，95%CI 1.13-4.44）、出生在瑞典以外（OR 2.21，95%CI 1.08-4.53）、以及接种过甲型肝炎、乙型肝炎或两者的疫苗（OR 1.92，95%CI 1.13-3.27）。
在国外发生偶然 UAI 的 MSM 需要增加对相关风险的认识，并且风险因地点和行为而异。卫生保健专业人员应关注出国旅行的 MSM 的预防需求，并提供咨询和性传播感染预防措施。
