为观察体质指数的动态变化 ,为卫生研究和政策制订提供依据 ,采用分层多阶段整群随机抽样的方法 ,对抽取的观察户连续观察测量。结果显示 ,从 1989年～ 2 0 0 0年BMI小于 18 5的人数百分比呈下降趋势 ,1989年为 7 3% ,2 0 0 0年为 3 5 %。超重和肥胖的人数百分比呈增加的趋势 ,从 1989年的 10 7%猛增到2 0 0 0年的 2 5 2 % ,平均每年增加 1 5 %百分点。2 0 0 0年超重肥胖百分比高低依次为城市 33 3%、县城 31 7%、郊区 2 4 6 %和农村 2 1 1%。提示超重肥胖率较高 ,增加较快 ,应列为重大公共卫生问题之一 。

To analysis the dynamic changes of body mass index (BMI) of adults, and provide basis for health research and policy\|making,using the random cluster sampling, a total of 480 households (urban 80, suburban 80, county neighboring communities 80, rural 240) in 24 different sites were selected. The adults of selected households were subjects. Data on height, body weight and household income etc were collected in autumn of every surveying year.The results showed that the rates of BMI<18\^5 cut\|off point declined with years, they were 7\^3% and 3\^5% in 1989 and 2000 respectively. The rates of overweight and obesity showed a steadily increasing tendency, rose up sharply from 10\^7% in 1989 to 25\^2% in 2000, about 1\^5% higher each year. The percentage of overweight and obesity altogether in 2000 ranked as urban 33\^3%, county 31\^7%, suburban 24\^6%, and rural 21\^4%. It suggested that the percentage of overweight and obesity increased quickly, have accounted for big part in population, and should be listed as one of major public health issues
