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

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.
