男男性行为人群中HIV/AIDS行为干预的动力学模型

Dynamics model of HIV/AIDS intervention in MSM population

通过动力学模型探讨了男男性行为者(men who have sex with men, MSM)中HIV的防治策略,研究发现:与实现联合国艾滋病规划署提出了"2030年终结艾滋病"的"3个90%"防治目标相比,若能做到一级预防,即增加对艾滋病易感者进行行为干预,如增加对易感者人群的宣传教育、提高有效的安全套的使用率等措施,才能更快地降低艾滋病感染率;在对抗MSM人群中的HIV传播过程中,对易感者的干预效果大于对感染者的干预效果.

This paper addresses the issue of HIV prevention in the men who have sex with men(MSM) population through the dynamics model. It suggests that in the context of "the three 90%" prevention targets set by UNAIDS the most effective measures to be taken at the present stage can be the increase of intervention among susceptible people,and concrete methods include education, increase of condom use and HIV testing. When these measures are in place, HIV infection can be better controlled in the local community.
