目的:探讨海南百岁老人糖尿病的分布特征及影响因素。方法:研究对象来自中国海南百岁老人队列研究，共1 002名百岁老人纳入分析。参考糖尿病防治指南的诊断标准，根据FPG水平和既往疾病史，将研究对象分为血糖正常组、空腹血糖受损组、糖尿病组。结果:百岁老人年龄为（102.77±2.55）岁，女性所占比例为82.0%。共有95名百岁老人患有糖尿病，糖尿病的患病率为9.5%。共有81名百岁老人患有空腹血糖受损，患病率为8.1%。百岁老人的FPG值为（5.12±1.44）mmol/L。43.5%的百岁老人FPG值集中在4.00~5.00 mmol/L，22.1%的百岁老人FPG值集中在5.00~6.00 mmol/L。TG升高和腹型肥胖可能与糖尿病患病风险有关。结论:海南百岁老人糖代谢状况优于其他年龄人群，且未呈现性别差异。“,”Objective:To investigate basic characteristics of diabetes prevalence and associated factors in centenarians in Hainan province of China.Methods:All the subjects were from China Hainan Centenarian Cohort Study. A total of 1 002 centenarians were included in the final analysis, who were divided into three groups: diabetes group, impaired fasting glucose (IFG) group, and normal glucose group according to the guideline.Results:The average age of centenarians was (102.77±2.55) years, and the proportion of females was 82.0%. There were 95 centenarians who suffered from diabetes, and the prevalence rate was 9.5%. There were 81 centenarians who had IFG, and the prevalence rate was 8.1%. The mean fasting plasma glucose (FPG) level of centenarians was (5.12±1.44) mmol/L, while 43.5% of centenarians had FPG levels ranging from 4.00 to 5.00 mmol/L and 22.1% of centenarians had the FPG levels ranging from 5.00 to 6.00 mmol/L. Increased triglyceride level and abdominal obesity might be associated with the risk for diabetes.Conclusion:The glycometabolism in centenarians in Hainan was better than that in other age groups, and no gender specific difference was observed.
