对糖耐量异常者的前瞻性观察是研究糖尿病病因和病理的重要方法。本组288例糖耐量异常者,随访5～12(平均8.7±2.6)年,其中48例发展为Ⅱ型糖尿病,作者用多因素方法分析了产生糖尿病的危险因素。方法门诊病人作100g口服葡萄糖耐量试验及胰岛素释放试验。如空腹血糖(葡萄糖氧化酶法)为5.6～6.7mmol/L和/或2小时血糖为7.2～13.3mmol/L者即按糖耐量异常进行随访观察。内容包括:①年 Prospective observation of impaired glucose tolerance is to study the etiology and pathology of diabetes an important method. 288 patients with impaired glucose tolerance were followed up for 5 to 12 years (average 8.7 ± 2.6) years. 48 of them developed type Ⅱ diabetes. The authors used multiple factors analysis to analyze the risk factors of diabetes. Methods Outpatients were given 100g oral glucose tolerance test and insulin release test. Such as fasting blood glucose (glucose oxidase) was 5.6 ~ 6.7mmol / L and / or 2-hour blood glucose was 7.2 ~ 13.3mmol / L who were impaired glucose tolerance were followed up.
