Abstract

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
