摘要: 在西北民族走廊地区测量了16个人群共6687例(男2983例,女3704例)的腰围和16项体成分值,将样本按腰围分成正常组、中心型肥胖前期组、中心型肥胖组。结果发现,西北民族走廊人群中心型肥胖率很高(男性为49.6% ,女性为49.5%)。相关分析显示,除水分率外,腰围与其他14项体成分指标都呈显著正相关,说明随着全身的体脂率、肌肉量、躯干四肢脂肪率和肌肉量的增大,会导致腰围增大。男性腰围正常组内脏脂肪等级(8.6±4.2)已经接近正常值的上限,中心型肥胖前期组(12.7±2.9)属于偏高水平,中心型肥胖组(15.7±3.1)已经达到高的水平;女性腰围正常组内脏脂肪等级(4.9±1.9)、中心型肥胖前期组(7.1±1.5)均为正常情况,中心型肥胖组(9.5±2.2)属于偏高水平。13个人群主成分分析结果显示,西北民族走廊人群具有北方少数民族肌肉较发达、脂肪率较高的共性,西北民族走廊的中心型肥胖组人群肌肉量、脂肪率出现明显的增大。

Abstract:

The waist circumference and 16 body composition values were measured in a total of 6687 cases (2983 males, 3704 females) from 16 populations in the Northwest Ethnic Corridor region, and the samples were divided into normal waist circumference, early central obesity, and central obesity groups according to waist circumference. The results showed that the prevalence of central obesity in the Northwest Ethnic Corridor was high (49.6% for males, 49.5% for females). Correlation analysis showed that in addition to percent body water, waist circumference was significantly positively correlated with other 14 body composition indexes, indicating that with the increase of percent body fat, total body muscle mass, trunk percent trunk fat and trunk muscle mass, waist circumference increased. The visceral fat grade (8.6±4.2) in the normal male waist circumference group was close to the upper limit of the normal value, the early central obesity group (12.7±2.9) was at a high level, and the central obesity group (15.7±3.1) had reached a high level. The visceral fat grade (4.9±1.9) in the normal group of women with normal waist circumference and the early central obesity group (7.1±1.5) were normal, and the central obesity group (9.5±2.2) was at a high level. The results of the principal component analysis of the 13 populations showed that the Northwest Ethnic Corridor population has the common characteristics of more developed muscles and higher fat rate of northern ethnic minorities. The muscle mass and fat rate of the central obese population in the Northwest Ethnic Corridor increased significantly.

Key words: population, waist circumference, central obesity, body fat, muscle mass
