1996年4～10月，在四川省20－74岁自然人群中经分层随机抽样3385人进行了非胰岛素依赖型糖尿病（NIDDM）现况调查。NIDDM和糖耐量低减（IGT）的患病率为5．11％和9．96％，其标化患病率分别为2．91％和5.63％。NIDDM患病率除性别外因人群的年龄、文化水平、职业等不同而存差异。患病率随年龄增加而增高，40岁以上尤为明显，文盲及离退休组患病率较其他文化水平和职业组为高，大、中城市及城镇的患病率明显高于农村、而农村中富裕区和贫困区的患病率又有区别。体质指数（BMI），职业性体力活动及其他病患病史对患病率有明显影响（RR2．3-5．6），NIDDM和IGT的8项体格指标均值均显著高于正常人群。本文同时分析了IGT患病率的分布，上述调查资料对我省糖尿病的进一步研究和防治具有积极意义。
From April to October 1996, 3385 non-insulin dependent diabetes mellitus (NIDDM) were surveyed in stratified randomized population of 20-74 year olds in Sichuan province. The prevalence rates of NIDDM and impaired glucose tolerance (IGT) were 5.11% and 9.96%, respectively. The prevalence rates of NIDDM and IGT were 2.91% and 5.63% respectively. The prevalence of NIDDM varies from sex to age due to the age, education level, occupation, etc. of the population. The prevalence increased with age, especially in those over 40. The prevalence of illiteracy and retired people was higher than that of other cultural levels and occupational groups. The prevalence rates in large, medium-sized cities and towns were significantly higher than those in rural areas. However, The prevalence of affluence and poor areas is different again. The body mass index (BMI), occupational physical activity and other medical history had a significant impact on the prevalence (RR2.3-5.6). The mean of 8 physical indexes of NIDDM and IGT were significantly higher than that of the normal population. This article also analyzed the distribution of IGT prevalence, the survey data on the further research and prevention and treatment of diabetes in our province has a positive meaning.
