中国汉族城市成年人身体肥胖指数值的纬度性分布

Body adiposity index values of Chinese urban Han adults distributed in different latitude areas

目的探讨中国城市成年人身体肥胖指数（BAI）值随纬度的变化规律。方法采用随机抽样方法,2009年~2013年测量城市汉族10 451例（男性5048例,女性5403例）（共31个调查地区）的身高、臀围值,计算身体肥胖指数值。结果 31个男性族群BAI均值在23.64~27.49之间,可分为3个等级：第1等级为BAI≥26.00,第2等级BAI在25.00~25.99之间,第3等级BAI〈25.00;31个女性族群BAI均值在27.56~30.80之间,女性BAI也可分为3个等级：第1等级为BAI≥30.00,第2等级BAI在29.00~29.99之间,第3等级BAI〈29.00。结论汉族31个城市族群臀围与纬度、身高与纬度、臀围与身高均呈正相关,BAI与臀围、BAI与纬度也均呈正相关,但BAI与身高不相关。

Objective To study the changes of body adiposity index （BAI） of Chinese urban adult with latitude. Methods Based on the measurement of stature and hip circumference of 10 451 Chinese urban Han of 31 districts form 2009 to 2013, and calculated their body adiposity index values, BAI. Results The average of BAI of 31 male groups was between 23.64 and 27.49. It was divided into 3 levels： the first level was BAI ≥ 26. 00, the second level was between 25.00 and 25.99, and the third level was BAI 〈 25.00 ; The average of BAI of 31 female groups was between 27.56 and 30. 80. It was divided into 3 levels： the first level was BAI≥30.00, the second level was between 29.00 and 29.99, and the third level was BAI 〈 29.00. Conclusion Hip circumference has a positively linear correlation with latitude, and stature has a positively linear correlation with latitude, hip circumference and stature have positively linear correlation, BAI has positively linear correlation with hip circumference and latitude, but BAI and stature hare no correlation of 31 urban Han groups.
