摘　　要：目的:探讨内蒙古达斡尔族成人示指、环指指长比(2D︰4D)与体质量指数(BMI)、腰臀比(WHR)及脂肪量的关系。方法:运用人体测量法,比较内蒙古莫力达瓦达斡尔族自治旗健康达斡尔族成人左手、右手、双手及右手-左手(DR-L)2D︰4D,BMI、WHR及脂肪量各均值,分析2D︰4D与BMI、WHR及脂肪量的相关性。结果:左、右手2D︰4D及双手表现为女性显著高于男性,相关分析显示女性右手、左手及双手2D︰4D与BMI、腰围、躯干及四肢脂肪量呈正相关,女性右手及双手2D︰4D还与臀围呈正相关。受试者工作特征曲线分析显示,通过右手2D︰4D、双手平均2D︰4D筛查肥胖有一定的效能,女性右手2D︰4D及平均2D︰4D的最佳切点分别为0.989及0.980,敏感度分别为46.5%、53.5%,特异度分别为78.9%、68.4%。结论:内蒙古达斡尔族成人女性2D︰4D与脂肪量相关。Objective:To investigate the relationship between digit ratio(2D︰4D)and body mass index(BMI),waist-hip ratio(WHR)and fat mass in Daur adults from Inner Mongolia.Methods:Using anthropometric measurements,the mean values of 2D︰4D ratios of the left hand,right hand,both hands,and the difference between the right and left hand(DR-L),as well as the mean values of BMI,WHR,and fat mass,in Daur adults from the Daur autonomous banner of Morin Dawa of Inner Mongolia were compared.The correlation between 2D︰4D and BMI,WHR,and fat mass were analyzed.Results:The 2D︰4D ratios in the left hand,right hand,and both hands were significantly higher in females than males.Correlation analysis showed that in females,the 2D︰4D ratios in the right hand,left hand,and both hands were positively correlated with BMI,waist circumference,trunk fat mass,and limb fat mass.Additionally,the 2D︰4D ratios in the right hand and both hands were positively correlated with hip circumference in females.Receiver operating characteristic curve analysis showed a certain effectiveness in screening obesity through the 2D︰4D ratio in the right hand and the average 2D︰4D ratio of both hands,the optimal tangent points of the 2D︰4D ratios in the right hand and average 2D︰4D ratio of both hands were 0.989 and 0.980,sensitivity were 46.5%and 53.5%,and specificity were 78.9%and 68.4%in females.Conclusion:There is a correlation between the 2D︰4D ratio and fat mass in Daur female adults from Inner Mongolia.
