中国12个地区中老年人糖尿病患病率调查

A survey of diabetes prevalence in the middle-aged and elderly Chinese from 12 areas of China

目的 调查中国 4 0～ 99岁一般人群中糖尿病和糖耐量低减 (IGT)的患病现状。方法采用分级整群抽样方法 ,在 1997年 8月～ 1998年 8月期间横断面调查中国 12个地区的 4 0～ 99岁居民2 9 5 5 8人。结果 中国 4 0～ 99岁一般人群中糖尿病的标化患病率为 5 .89% (95 %CI:5 .6 2 %～ 6 .16 % ) ,IGT标化患病率为 5 .90 % (95 %CI:5 .6 3～ 6 .17% ) ,12个地区之间的糖尿病标化患病率和IGT标化患病率有显著性区别 (χ2 =84 .5 ,P <1× 10 -5) ,城乡之间的糖尿病患病率 (城 :6 .8% ,乡 :3.8% ,χ2 =12 4 .2 ,P <1× 10 -5)和IGT患病率 (城 :6 .1% ,乡 :5 .3% ,χ2 =11.6 ,P =0 .0 0 0 7)有显著性区别 ,总体上各年龄组之间的糖尿病患病率 (χ2 =12 4 .2 ,P <1× 10 -5)和IGT患病率 (χ2 =11.6 ,P =0 .0 0 0 7)也有显著性区别 ,并呈现增龄性上升的趋势。结论 中老年人糖尿病患病率有地区和城乡差别 。

Objective To investigate the prevalences of diabetes mellitus and impaired glucose tolerance (IGT) in general population aged 40～99 years old in China. Methods Crossover section epidemiology survey was applied throughout random stratified population sampling, 29558 Chinese residents over 40 years old from 12 areas in mainland of China were screened and interviewed from Aug. 1997 to Aug. 1998. Results Theaggregateage adjustedstandardizationprevalenceof diabetes was 5.89% (95% CI:5.62%～6.16%), and that of IGT was 5.90% (95% CI:5.63%～6.17%). There was significant variations (χ 2=84.5, P<1×10 -5 ) of standardized prevalence of diabetes among 12 areas in China. The prevalence of diabetes (urban: 6.8%, rural: 3.8%) varied significantly (χ 2=124.2, P<1×10 -5 ) about one time more in urban population than that in rural populations. There was a significant difference of IGT prevalencebetweenurban(6.1%)andrural(5.3%)populationsinChina(χ 2=11.6,P=0.0007). The prevalence of diabetes increased with ageing in middle and old age population, i.e. the prevalence of diabetes was 2.0% in age 40 years old group, 5.4% in age 45～64 years old groups, 10.9% in age 65～74 years old groups and 11.6% in age 80～99 years old group. Compared the prevalences of diabetes and IGT by specific age groups, it showed there were significant differences (DM: χ 2=124.2, P<1×10 -5 ; IGT: χ 2=11.6, P=0.0007) among groups. Conclusion The prevalence of diabetes mellitus is different among areas and between urban and rural areas in middle and old Chinese population in China. Diabetes prevalence increases with ageing.
