[目的 ] 了解高危 (高血压、高血脂、肥胖、家族史、老龄 )人群中 2型糖尿病的患病率。 [方法 ] 选具有 1种或 1种以上高危因子的 42 3人 ,测餐后的毛细血管全血糖 ,若 >6 .7mmol/L者 ,接受OGTT。 [结果 ] 糖尿病患病率为 7.80 % ,糖耐量减退 (IGT)为 16 .78%。糖尿病与IGT者与血糖正常者比较 ,年龄 ,体重指数 (BMI)均显著升高 ,具有高危因子的机会明显增加。 [结论 ] 高危人群调查比普查具有更重要的价值。
[Objective] To understand the prevalence of type 2 diabetes in high-risk (hypertension, hyperlipidemia, obesity, family history, old age) population. [Methods] A total of 423 individuals with one or more risk factors were selected and postprandial capillary blood glucose was measured. If >6.7 mmol/L, OGTT was accepted. [Results] The prevalence of diabetes was 7.8% and impaired glucose tolerance (IGT) was 16.78%. The age and body mass index (BMI) of patients with diabetes and IGT were significantly higher than those with normal blood glucose, and the chance of having high-risk factors increased significantly. [Conclusion] Surveys of high-risk populations have more important value than census.
