目的 :了解重庆地区老年人 2型糖尿病 (DM )和糖耐量低减 (IGT)的患病情况及相关疾病。方法 :采用整群抽样的方法对重庆地区 1791例 6 0岁以上老年人群进行横断面研究。结果 :(1) 2型DM患病率为 15 .6 % ,IGT患病率为 2 0 .5 %。餐后血糖是诊断老年人 2型DM的一个敏感指标。 (2 ) 70岁以上组与 6 0～ 6 9岁组比较 2型DM和IGT的患病率有显著性差异 ,其中IGT患病率的差异尤为显著。 (3)Logistic回归分析结果表明 ,高血压、高TG血症、肥胖和中心性肥胖均为 2型DM和IGT患病的危险因素。结论 :老年人 2型DM和IGT患病率随年龄的增长而增加 ,餐后血糖是早期诊断老年人 2型DM的敏感指标 ;高血压、高TG血症、肥胖和中心性肥胖是影响老年人 2型叫患病率的主要相关疾病。
Objective: To understand the prevalence and related diseases of type 2 diabetes (DM) and impaired glucose tolerance (IGT) in the elderly in Chongqing. Methods: A total of 1791 elderly population over the age of 60 in Chongqing were studied by cluster sampling method. Results: (1) The prevalence of type 2 DM was 15.6% and the prevalence of IGT was 20.5%. Postprandial blood glucose is a sensitive indicator of the diagnosis of type 2 DM in the elderly. (2) The prevalence of type 2 DM and IGT in 70-year-old group was significantly different from that in 60-year-old group, of which the difference of IGT prevalence was significant. (3) Logistic regression analysis showed that hypertension, hypercholesterolemia, obesity and central obesity were the risk factors of type 2 DM and IGT. CONCLUSIONS: The prevalence of type 2 DM and IGT in the elderly increases with age, and postprandial blood glucose is a sensitive indicator of early diagnosis of type 2 DM in the elderly. Hypertension, hypercholesteremia, obesity and central obesity are the elderly People type 2 is called the prevalence of major related diseases.
