1989年山西、北京和辽宁三地44747例糖尿病患病率普查结果表明,糖尿病及糖耐量低减(IGT)分别为2.02％及2.95％,前者比1979年明显增高。北京和辽宁地区二者增高尤为显著,而在山西贫困山区二者仍极低。造成这种差异的原因可能是山西忻州农民热量摄取和超重与肥胖的比例均明显低于北京和辽宁等地。糖尿病及IGT患病率随年龄增高而增高,峰值在60余岁年龄组。目前我国糖尿病及IGT患者仍以非肥胖者为多,但在超重及肥胖组中,二者的患病率显著高于低体重或正常体重组。说明老龄化趋势、体力活动不足和热量摄取过多导致的肥胖,是造成糖尿病及糖耐量低减患病率快速增加的重要原因。本调查发现男性糖尿病患病率高于女性,其原因和意义有待研究。
The prevalence of 44,747 cases of diabetes in Shanxi, Beijing and Liaoning Province in 1989 showed that the prevalence of diabetes and impaired glucose tolerance (IGT) were 2.02% and 2.95% respectively, the former was significantly higher than that in 1979. Both Beijing and Liaoning provinces have seen particularly pronounced increases, while both in impoverished mountain areas in Shanxi remain extremely low. The reason for this discrepancy may be that the caloric intake and overweight and obesity proportion of farmers in Xinzhou, Shanxi Province are significantly lower than those in Beijing and Liaoning. Diabetes and IGT prevalence increased with age, the peak in the 60-year-old age group. At present, there are still more non-obese people with diabetes and IGT in our country, but the prevalence of both is significantly higher in overweight and obesity groups than in low-weight or normal-weight groups. It shows that aging, physical inactivity and overweight caused by excessive calorie intake are the important reasons for the rapid increase of prevalence of diabetes and impaired glucose tolerance. The survey found that male prevalence of diabetes than women, the reason and significance to be studied.
