摘　　要：目的探讨老年体检人群中骨密度与人体成分指标的关系,从而为老年人群的骨骼健康管理提供科学依据。方法自2014年9月至2019年3月在解放军总医院健康管理研究院接受健康体检的所有老年健康体检者(年龄≥60岁)为研究对象;记录人口学基本信息、吸烟和饮酒嗜好,测量身高、体质量,利用人体成分仪(生物阻抗法)检测肌肉量、体脂肪量,计算体质指数(BMI)、体脂肪率和骨骼肌质量指数(SMI);测量骨密度值,分别按照BMI和骨密度检测的T值分组,进行对比分析。用χ^(2)及t检验进行率的比较,多组间比较用方差分析,影响因素分析用线性相关分析。结果共纳入13561例研究对象,其中,男性7481例,占55.17%;女性6080例,占44.83%。骨质正常3101例,占22.87%;骨质减少5340例(39.39%),骨质疏松5120例(37.76%)。在骨质疏松人群中,女性的比例明显高于男性(χ^(2)=1400,P<0.01)。骨密度(BMD)与体质量(β=0.3576,P<0.01)、肌肉量(β=0.5177,P<0.01)、BMI(β=0.1024,P<0.01)和SMI(β=0.3663,P<0.01)均呈显著性正相关,与体脂肪率呈显著性负相关(β=-0.3185,P<0.01)。按照BMI分组后,低体质量组的骨质疏松比例最高,Ⅱ度肥胖组的骨质疏松比例最低。结论增加体质量,尤其增加肌肉量,同时控制体脂肪率有利于增加老年人的骨密度。Objective To explore the relationship between bone mineral density and body composition index in elderly people,so as to provide scientific basis for bone health management in the elderly.Methods All elderly healthy subjects(age≥60 years old)who received physical examination in the Institute of Health Management of PLA General Hospital from September 2014 to March 2019 were included.Demographic information,smoking and drinking habits were recorded;height and body mass,muscle mass and body fat mass(bioimpedance method)were measured;Body mass index(BMI),body fat percentage and skeletal muscle mass parameter(SMI)were calculated;bone mineral density(BMD)was measured and grouped according to BMI and T value for comparative analysis.Chi-square test and t-test were used to compare the rates,analysis of variance was used to compare the multiple groups,and linear correlation analysis was used to analyze the influencing factors.Results A total of 13561 subjects were included,7481 were males,accounting for 55.17%;6080 cases were female,accounting for 44.83%.Three Thousand one hundred and one patients(22.87%)had normal bone mass.There were 5340 cases of osteopenia(39.39%)and 5120 cases of osteoporosis(37.76%).In the population of osteoporosis,the proportion of female was significantly higher than that of male(χ^(2)=1400,P<0.01).Bone mineral density(BMD)was significantly positively correlated with body mass(β=0.3576,P<0.01),muscle mass(β=0.5177,P<0.01),BMI(β=0.1024,P<0.01)and SMI(β=0.3663,P<0.01),and significantly negatively correlated with body fat percentage(β=-0.3185,P<0.01).According to BMI groups,low body mass group had the highest percentage of osteoporosis,Ⅱdegree of obesity group and the lowest proportion of osteoporosis.Conclusion Increasing body mass,especially muscle mass,is beneficial to increase bone density in the elderly.
