目的了解目前农村2型糖尿病的患病率,比较两个时期农村2型糖尿病患病率及其危险因素暴露率时间趋势。方法2007～2008年在河南省新安县两个乡镇整群随机抽取35～74岁农村人群16953人,对其进行代谢综合征患病率的调查,并和2000～2001年InterAsia研究的中国农村样本人群7647人进行比较。结果经2000年全国人口标化后,农村2型糖尿病患病率在七年间从5.27%上升到7.72%(χ2=8.57,P<0.01)。2000～2001年研究表明,2型糖尿病患病率随年龄的增长而上升(χ2=50.1958,P<0.01);2007～2008年的研究显示,55～64岁年龄组2型糖尿病患病率最高(12.64%)。比较两项研究发现,高血压、中心性肥胖、血脂异常的标化暴露率分别从26.82%、26.39%、20.45%升高到29.82%、46.1%、44.20%。结论农村2型糖尿病的患病率增长迅速且有年轻化的趋势,主要危险因素暴露率也呈上升趋势,预防控制刻不容缓。

Objective To investigate the secular trend of prevalence and risk factors for type 2 diabetes mellitus(T2DM) in the rural Chinese population.Methods 16953 participants aged 35 to 74 years old participated in a cross-sectional study in a Henan rural area in 2007-2008.The InterAsia study which is a nationally representative sample of rural Chinese residents was done in 2000-2001.The rural Chinese adult participants in InterAsia study were compared with the 2007-2008 data to analyze the secular trend of prevalence and risk factors of T2DM.Results In 2007-2008,the aged-adjusted prevalence of T2DM was 7.72%(male 7.71%,female 7.73%).The aged-adjusted prevalence of T2DM elevated from 5.27% to 7.72% during seven years.The prevalence of T2DM was progressively increased with age from 2000-2001,but the prevalence of T2DM for the participants aged from 55 to 64 was highest after seven years in 2007-2008.Compared two studies,the exposed rates of hypertension,abdominal obesity,dyslipidemia were increased from 26.82%,26.39%,20.45% to 29.82%,46.1%,44.20%.Conclusion The prevalence of T2DM and it 's risk factors increase rapidly in the rural Chinese population,and the intervention program are urgently needed.
