不同指标用于2020年上海市20~59岁成年人超重与肥胖人群分布评价比较

目的：描述上海市20～59岁成年人体脂率（BF%）、身体质量指数（BMI）、腰围（WC）等形态指标人群分布特征，探讨BF%、BMI、WC的异同点。方法：基于2020年第五次国民体质监测上海市20～59岁成年人数据库，纳入26 826名研究对象，分析不同性别、年龄组成年人BF%、BMI、WC特征以及相关人群分布。结论：上海市成年男性WC随年龄增长而增大，成年女性BF%和WC随年龄的增长而增长。以BF%、BMI、WC 3个指标评判上海市20～59岁成年人超重与肥胖情况时存在着一定的差异。上海市成年男性以WC为标准检出肥胖率最高，以BF%为标准检出超正常标准率最高；上海市成年女性以BF%为标准检出超正常标准率及肥胖率最高。BMI与BF%相结合，或与WC相结合，可以反映身体脂肪含量及比例，以及脂肪分布。

A Comparative Study of Different Indicators Used to Evaluate the Distribution of Overweight/Obese Adults Aged 20-59 Years in Shanghai in 2020

Objective: To describe the distribution characteristics of body fat percentage, BMI and waist circumference among adults aged 20-59 in Shanghai in 2020, as well as the distribution characteristics of the corresponding population, and to explore the similarities and differences between body fat percentage (BF%), body mass index (BMI) and waist circumference(WC). Methods: Based on the database of adults aged 20-59 in the 5th National Fitness Surveillance in Shanghai 2020, this study included 26826 research subjects, and analyzed the body fat rate, BMI, waist circumference characteristics and related population distribution in different gender and age groups. Results: The waist circumference of Shanghai adult men increases with age, and the body fat percentage and waist circumference of adult women increase with age. There are certain differences in judging the overweight and obesity of adults aged 20-59 in Shanghai by BMI, body fat percentage, and waist circumference. Shanghai adult men have the highest obesity rate judged by waist circumference, and the highest overweight and obesity rate judged by body fat percentage; Shanghai adult women have the highest overweight and obesity rate judged by body fat percentage method. Body mass index combined with body fat percentage, or combined with waist circumference, can reflect body fat content and proportion, as well as fat distribution.
