目的分析男男性行为人群（MSM）指长比特点及其与拥有性伴类型的关系。方法于2014年12月至2015年4月，以前往昆明市彩云天空健康咨询服务中心进行咨询和检测的MSM作为调查对象。纳入标准为18岁以上、有过同性性行为、HIV阴性的男性，排除标准为纳入标准以外及由于残疾不能参加者，最终纳入调查对象115名。本研究采用民族匹配的1：1配对病例．对照研究，选取115名非MSM为对照组。根据性伴数不同，将MSM组分为拥有固定性伴组和多性伴组两个亚组。采用问卷调查收集所有调查对象的人口学特征，及MSM组的艾滋病知识、近6个月的性行为情况、性取向、寻找性伴场所、性角色、毒品使用情况、预防服务等相关信息，并根据人类体质测量法分别测量MSM组和对照组双手第2～5指的长度，采用nD表示。采用x。检验比较MSM组和对照组人口特征差异，采用t检验比较两组指长比差异。结果115名MSM中，拥有固定性伴者占26％（30名），拥有多性伴者占74％（85名），其指长比的分布特点为2D：3D〈2D：4D〈3D：4D〈2D：5D〈4D：5D〈3D：5D。MSM组右手213：4D和2D：5D分别为0．9577±0．0481和1．2298±0．0834，均大于对照组（0．9414±O．0380和1．2041±0．0695）（t值分别为2．84、2．54，P值分别为0．005、0．012）。拥有固定性伴和多性伴MSM右手的2D：4D分别为0．9622±0．0510和0．9561±0．0473，均大于对照组（t值分别为2．98、2．83，P值分别为0．027、0．015），拥有固定性伴和多性伴MSM的2D：4D差异无统计学意义（t=0．14，P=0．397）。结论拥有多性伴MSM的比例较高，感染HIV的风险较高；右手2D：4D较高者为MSM可能性较高，但无法区分性伴类型。
