辽宁农村地区成年人群超重和肥胖的流行病学调查

Epidemiology of obesity and overweigit among rural middle-aged and elderly populations in Liaoning province

目的了解辽宁农村成年人群超重和肥胖的流行特征,为农村肥胖的防治提供科学依据。方法用分层整群随机抽样的方法,于2004—2006年对辽宁省阜新县8个乡镇共计95个行政村内所有≥35岁常住人群(≥5年)进行调查,按中国肥胖问题工作组推荐的中国成人超重肥胖诊断标准,对肥胖、超重患病情况进行统计分析。结果该地区人群超重及肥胖率分别为29.5%和5.3%,女性超重和肥胖率为32.5%和7.0%,男性为26.5%和3.5%,女性明显高于男性(P<0.01)。无论男女,超重及肥胖率在不同年龄组均不同,差别具有统计学意义(P<0.05),但是没有表现出一定的趋势。腹型肥胖率为43.9%,女性高于男性(53.5%vs34.1%,P<0.01);男性腹型肥胖率随着年龄的增加而逐渐降低(趋势χ2检验,P<0.05);女性腹型肥胖率在不同年龄组均不同。结论辽宁农村地区成年人肥胖患病率较低,但超重率较高,女性高于男性。腹型肥胖患病率亦很高。

Objective To investigate the current epidemiological characteristics of obesity and overweight among the rural middle-aged and elderly populations in Liaoning province and to provide scientific basis for the prevention and treatment of obesity. Methods Through cluster multistage and random sampling to a resident （≥5 years） group of 45, 925 people aged ≥35 years old in eight small towns of Liaoning province so as to understand the prevalence of overweight and obesity based on diagnostic criteria of Chinese adults recommended by the Working Group on Obesity in China. Results The total prevalence rates of overweight and obesity was 29.5% and 5.3% respectively. The prevalence of overweight and obesity of women was 32.5% and 7.0% respectively, significantly higher than that of men （26.5% and 3.5%, P 〈 0.01 ）. No matter male or female, it was obviously different in the different age groups. The total prevalence rate of abdominal obesity was 43.9 %. The prevalence rate of abdominal obesity of female was higher than that of male （53.5 % VS 34.1%, P 〈 0.01 ）. In men, the prevalence rate of abdominal obesity was decreased gradual- ly with the increase of age（linear trend test, P〈0.05）. In women,the prevalence rate of abdominal obesity was different in the different age groups. Conclusion The prevalence rate of obesity among the rural middle- aged and elderly populations in Liaoning province is quite low, but the rates of overweight and abdominal obesity are relatively high,
