摘要：

目的 利用生物电阻抗分析法，分析甘肃东乡族成人非脂肪组织体成分变化特点。 方法 采用横断面整群分层随机抽样方法，应用体成分分析仪，测量491例甘肃省东乡族自治县20岁以上东乡族成人非脂肪组织体成分指标。 结果 甘肃东乡族成年男性去脂体重、骨量、肌肉、蛋白质、体液量及构成比均高于女性 (P<0.01)，且男性各年龄组的骨量、肌肉量、蛋白质、体液量均高于女性 (P<0.01)。骨量、肌肉量在同一性别中随年龄变化趋势相同，男性均在40岁年龄组达峰值后下降；女性先降后升，在40岁年龄组达峰值后又下降。男性的蛋白质在30岁年龄组达峰值后下降；女性的蛋白质呈持续下降状态。男女性的躯干肌肉量分别在50岁年龄组和40岁年龄组达峰值后下降。男女性的双上肢肌肉量、体液量均在40岁年龄组达峰值后逐渐下降。男性的双下肢肌肉量除在40岁年龄组稍有回升，总体呈下降趋势；女性的双下肢肌肉量呈持续下降状态。男女性的细胞内液量均先降后升，在40岁年龄组达峰值后又下降。男女性的细胞外液量分别在50岁年龄组和40岁年龄组达峰值后稍有下降。 结论 甘肃东乡族成年男性的非脂肪组织体成分高于女性。随着年龄的增长，非脂肪组织体成分均发生变化，除双上肢肌肉量、体液量、细胞内液外，其余体成分的变化趋势均存在性别差异。总体呈现出，东乡族成年女性非脂肪组织体成分量少于男性，部分无峰值呈持续下降或达峰值早，下降早，达峰值后下降趋势缓于男性的特点。

Abstract:

Objective To analyze the changing characteristics of non-fat tissue body composition in Dongxiang adults of Gansu by a bioelectrical impedance analysis method. Methods A total of 491 Dongxiang adults aged over 20 years in Dongxiang autonomous county of Gansu Province were selected by the cross-sectional stratified random sampling method. The non-fat tissue body composition indexes were measured by body composition analyzer. Results The mass to constituent ratio of lean body mass, bone mass, muscle mass, protein and total body water were higher in male adults of Dongxiang in Gansu than in female (P<0.01), and bone mass, muscle mass, protein and total body water were same in different age groups. Bone mass and muscle mass showed the same trend in the same gender. One of the peaks of them was in 40 age group in male adults, and they decreased at first and then increased up to peak in 40 age group in female. The protein in male decreased after the peak of 30 age group, and decreased in female. Trunk muscle mass in male and female decreased after the peaks of 50 age group and 40 age group respectively. Double upper limbs muscle mass and total body water in both decreased after the peak of 40 age group. Double lower limbs muscle mass in male showed a downward trend except that there was a slight rebound in 40 age group, and always decreased in female. Intracellular water decreased at first and then increased up to peak in 40 age group in both. Extracellular water in male and female decreased slightly after the peaks of 50 age group and 40 age group respectively. Conclusion Non-fat tissue body composition indexes in Dongxiang adults of Gansu in male are higher than in female in different age groups and all of them changed with age. There are gender differences in the trend of the remaining body composition except double upper limbs muscle mass, total body water and Intracellular water. In general, the characteristics of non-fat tissue body composition in female adults of Dongxiang are less mass than in male, decrease continuously with no peak of partial body composition or earlier peak, decrease earlier, and decrease more slowly than in male.
