男男性行为人群个体HIV感染风险评估模型研制进展及启示

Research progress and enlightenment of HIV infection risk assessment model in men who have sex with men

男男性行为人群（MSM）高危性行为发生率高，是艾滋病、梅毒等性传播疾病感染的高危人群，也是传播控制的重点人群。但是，MSM中的每个个体由于其社会人口学特征、性行为特征、性行为网络等因素的差异，感染HIV的风险也存在差异。为了让具有男男性行为的个体了解自身感染HIV的风险，以及提高预防干预措施的针对性，建立适用于中国MSM的个体HIV感染风险评估模型势在必行。本文对已建立的MSM的HIV感染风险评估模型进行综述，并提出建立中国MSM的HIV感染风险评估模型时可使用的方法、可纳入考虑的条目以及相关注意事项，为今后中国风险评估模型的建立提供一些参考与建议。

The incidence of high-risk sexual behaviors among men who have sex with men （MSM） is high, indicating that MSM is the high-risk population of HIV/AIDS, syphilis and other sexually transmitted infections （STIs）, and also the key population of transmission control. However, the risk of HIV infection is different between individual MSM due to differences in socio-demographic characteristics, sexual characteristics, sexual networks and other factors. It is imperative to establish an HIV infection risk assessment model for MSM in China, to allow for MSM to quantitatively recognize their risk of HIV infection as well as to allow for implementation of tailored HIV prevention and intervention programs targeting MSM at greatest risk for HIV infection. The present study reviewed all published HIV infection risk assessment models among MSM in the world, and put forward the workable methods, potential items and precautions to develop an HIV infection risk assessment model among MSM in China.
