江苏省成年人超重和肥胖的流行趋势研究

Prevalence and Trends of Overweight and Obesity in Jiangsu Adults

目的:分析江苏省成年人超重和肥胖患病率的变化和流行特点,为肥胖症预防和控制提供依据。方法:利用2000年、2005年、2010年三次合计85362个样本的江苏省国民体质监测资料,分析比较10年间江苏省成年人超重率和肥胖率的变化特征。超重和肥胖采用中国人群BMI标准评价。结果:(1)10年间江苏省成年居民标化超重率和肥胖率分别增加了8.7%和43.4%,其中城镇分别增加3%和20.8%,同期农村的超重率和肥胖率大幅度增加了13.7%和77.8%,2010年超重率和肥胖率分别达到36.4%和11.9%,全省估计的超重人数增加了343.9万,肥胖人数增加了281.7万;(2)年龄期间队列分析,各出生队列的超重率和肥胖率在全年龄段均呈现上升趋势,45岁前增幅较大,50岁后增幅平缓,10年间男性的肥胖率增幅高于女性;(3)多因素logistic回归的调整OR值为:男性1.693(女性参照),苏中1.147和苏北1.387(苏南参照),城镇1.127(农村参照),2005年度1.138和2010年度1.291(2000年参照),所有P<0.001。结论:江苏省成年居民超重率和肥胖率居呈现快速上升的趋势,45岁以前人群、农村地区人群肥胖率增幅较快,是今后肥胖控制的重点群体;不同年龄、性别、城乡、南北地域、监测年度的超重和肥胖风险存在差异。

Objective:To analyze the prevalence and trends of overweight and obesity in Jiangsu adults from 2000 to 2010and to provide scientific basis for preventive measures against obesity.Methods:The data from 2000,2005,2010'national physical fitness monitoring in Jiangsu province'were used to analyse the prevalence and trends of overweight and obesity.Overweight and obesity were defined by BMI with Chinese standard for adults.Results:(1)The overall prevalence of overweight and obesity in Jiangsu adults was increased by 8.7% and 43.4%respectively during the period of 2000-2010,among which urban adults increased by 3% and 20.8%and accordingly rural resident increased by 13.7% and 77.8%.Prevalence of overweight and obesity reached 36.4and 11.9% in2010 and thus acquired the increase about 3.439 million and 2.817 million of estimated overweight and obese population.(2)Ageperiod-cohort analysis showed that prevalence of overweight and obesity were on the rise in all birth cohort.The rapid increase displayed in those of less than 45 years old and slow increase maintained in those of over 50.(3)Adjusted odds ratio value in multivariate logistic regression model for overweight and obesity respectively reached 1.693 to men(VS women),1.147 to middle Jiangsu and 1.387 to north Jiangsu(VS south Jiangsu),1.127 to urban(VS rural),1.138 to 2005and 1.291 to 2010(VS 2000)Conclusions:The prevalence of overweight and obesity in Jiangsu population was increased rapidly in the past decade.Rural residents and those population of less than 45 years old would be the key object for obesity control in the future.
