用腹围、腹臀比评价超重、肥胖标准

Overweightness and obesity evaluation standard by abdominal circumference and abdominal hip rate

目的：比较腹围、腹臀比与身体质量指数（BMI）及体脂率的相关性，探讨用腹围、腹臀比评价超重和肥胖的标准。方法：2010年在安徽滁州和江苏淮安调查了1426例汉族成年人的身高、体质量、腹围、臀围、肱三头肌皮褶、肩胛下皮褶，通过身高、体质量计算BMI，通过肱三头肌皮褶、肩胛下皮褶计算体脂率，通过腹围、臀围计算腹臀比。结果：江淮地区汉族男性超重率为34.72%，肥胖率为14.25%；女性超重率为30.73%，肥胖率为13.23%。江淮汉族男性、女性不同年龄组间的身高、腹围、臀围、BMI值、腹臀比、体脂率以及女性体质量值的差异具有统计学意义。随着腹臀比的增大，超重率、肥胖率比例越来越高。随腹围值、腹臀比的增大，江淮汉族男性和女性的BMI值、体脂率呈线性增大，身体密度呈线性减小。腹围评价超重标准估计在900～999mm之间，肥胖标准在1000mm以上。腹臀比评价超重标准估计在0.90～1.09,肥胖标准在1.10以上。结论：腹围、腹臀比与BMI关系密切，可作为对超重、肥胖进行评价的指标。

Objective： To compare the correlation of abdominal circumference, abdominal hip ratio with body mass index （BMI） and body fat rate so as to explore overweightness and obesity evaluation standard by abdominal circumference and abdominal hip rate. Methods： Variables including stature, body weight, abdominal circumference, hip circumference, triceps skinfold, and subscapular skinfold of 1 426 adults from Chuzhou of Anhui province and Huaian of Jiangsu province were measured in 2010. Stature and body weight were computed as the BMI; triceps skinfold and subscapular skinfold were computed as the body fat rate; abdominal circumference and hip circumference were computed as the abdominal hip rate. Results： The overweight rate of males was 34. 72 percent, while the obesity rate of males was 14. 25 percent. The overweight rate of females was 30. 73 percent, while the obesity rate of females was 13.23 percent. The six indexes of males and females （stature, abdominal circumference, hip circumference, BMI, abdominal hip rate and body fat rate） showed statistical significance among age groups, while the weight index of females had statistical significance among age groups. With the increase of abdominal hip rate, the overweightness and obesity rate became higher, and the BMI value increased. With increase of the abdominal circumference and abdominal hip rate, the BMI and body fat rate showed linear rise, while the body density was linearly diminished between males and females. The overweightness evaluation standard of abdomen circumference was 900-999 mm; the obesity evaluation standard of abdomen circumference was larger than 1 000 mm. The overweightness evaluation standard of abdominal hip rate was 0. 90-1.09, and the obesity evaluation standard of abdominal hip rate was larger than 1.10 at the same time. Conclusion： Both abdominal circumference and abdominal hip rate have close relations with BMI. They can be used as the standard to appraise overweightness and obesity.
