艾滋病是由人类免疫缺陷病毒(HIV)感染所致,目前尚缺乏有效的药物和疫苗等医疗手段,健康教育和行为干预便成为预防艾滋病的重要策略。男男性接触(men who have sex with men,MSM)人群普遍存在多性伴侣、无保护性的肛交等高危行为,易造成艾滋病病毒感染,是STD/AIDS三大核心人群之一[1],是中国艾滋病(AIDS)和性病(STD)防治工作的重点人群之一,因此MSM高危行为干预已纳入艾滋病/性病干预的重要工作内容[2]。该文从MSM人群的基本概念、人群规模估计及其HIV流行状况、结合目前已开展的健康教育以及行为干预等方面进行综述。
AIDS is caused by the human immunodeficiency virus (HIV) infection. Currently there is a lack of effective medical means such as drugs and vaccines. Health education and behavioral interventions have become important strategies for preventing AIDS. Men who have sex with men (MSM) are prevalent in polygamous, unprotected anal sex and other high-risk behaviors that can easily lead to HIV infection and are one of the three core STD / AIDS populations [1]. China is one of the key populations in the prevention and treatment of AIDS and STD. MSM interventions in high-risk behaviors have therefore been included in the important work of AIDS / STD intervention [2]. This article reviews the basic concepts of MSM population, population size estimation and HIV prevalence, combined with the current health education and behavioral interventions.
