利用１９８９年对８省的１６市３２县成人居民的调查结果，依据我国行政区划分，按城市、县城、郊区、农村４类不同生活特点地区的高中低收入分层进行分析，结果表明，城市和县城居民热能摄入低于郊区和农村。来源于动物性食物的热能，城市和县城占１１％－１３％，郊区和农村只占５％－９％左右，各类地区来源于动物性食物的蛋白质和动物性脂肪随经济收入的上升而增加。调查人群成人（２０－４５岁）超重（ＢＭＩ≥２５．０）的检出率在７％－１２％之间，消瘦（ＢＭＩ＜１８．５％）检出率在７％－１０％之间。城市和县城居民超重检出率显著高于郊区和农村居民（Ｐ＜０．００１）。低收入组的超重检出率低于中高收入组（Ｐ＜０．００１），体质指数（ＢＭＩ）随热能、蛋白质、脂肪等营养素摄入量的增加而升高。
Based on the survey results of 32 adult residents in 16 cities and 16 cities in 8 provinces in 1989 and according to the division of administrative regions in our country, the analysis of high school and low income stratification in four different life characteristics areas of cities, counties, suburbs and rural areas shows that urban and County residents calorie intake is lower than the suburbs and rural areas. The heat energy from animal foods accounts for 11% -13% in cities and counties, while the suburbs and rural areas account for only 5% -9%. The protein and animal fat derived from animal foods in all kinds of areas increases with the increase of economic income increase. The detection rate of overweight (BMI≥25.0) among adults (20-45 years old) in the survey ranged from 7% to 12%, and the detection rate of emaciation (BMI <18.5%) was between 7% and 10% . The detection rate of overweight in urban and county residents was significantly higher than that in suburbs and rural residents (P <0.001). The detection rate of overweight in low-income group was lower than that of middle- and high-income group (P <0.001). The body mass index (BMI) increased with the increase of nutrient intake such as heat energy, protein and fat.
