长沙市５１２４人糖尿病流行病学抽样调查表明：糖尿病（ＤＭ）和糖耐量低减（ＩＧＴ）标化患病率分别为３．０６％和３．９６％，且随年龄增加而升高；≥６５岁组ＤＭ和ＩＧＴ均高达１２．６６％；男女ＤＭ患病率无明显差异，ＩＧＴ女性高于男性；新诊断的ＤＭ患者７８．８％无症状；ＤＭ组和ＩＧＴ组的ＢＭＩ，标准体重百分数，腰围，臀围及腰围／臀围值均较正常对照组高；从消瘦到肥胖其患病率依次递增；ＤＭ组及ＩＣＴ组的平均收缩压明显高于正常对照组（Ｐ＜０．０１），平均舒张压亦较正常对照组高（Ｐ＜０．０５），而两组间血压无统计学差异（Ｐ＞０．０５）。结果提示，年龄、体重及血压等是糖尿病患病的重要影响因素。
The prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) in Changsha 5124 people was 3.06% and 3.96%, respectively, and increased with age; The DM and IGT of 65-year-old group were as high as 12.66%. There was no significant difference in the prevalence of DM between male and female, IGT female was higher than male, 78.8% of newly diagnosed DM patients were asymptomatic, Waist circumference, hip circumference and waist / hip circumference were higher than those in normal control group. The prevalence of obesity increased from obese to obesity in average. The average systolic blood pressure in DM group and ICT group was significantly higher than that in normal control group (P <0. 01). The average diastolic blood pressure was also higher than that of the normal control group (P <0.05), but there was no significant difference in blood pressure between the two groups (P> 0.05). The results suggest that age, weight and blood pressure are the important influencing factors of diabetes.
