目的 研究杭州地区部分老年体检人群糖化血红蛋白（glycosylated hemoglobin，HbA₁c）水平的分布情况。方法 收集1524例年龄大于60岁的体检人员样本，经全自动糖化血红蛋白分析仪检测HbA₁c(%)水平，分析性别及年龄对HbA₁c的影响，并比较HbA₁c参考值及2010年糖尿病诊断新标准对老年人群糖尿病筛查的价值。结果 老年人中男性与女性HbA₁c水平比较差异无统计学意义，60～69岁组中男、女性HbA₁c分别为（5.86±0.74）%，（5.77±0.67）%，70～79组中男、女性HbA₁c分别为（5.90±0.91）%，（5.96±0.78）%，男性和女性60~ 69岁组与70 ~ 79岁组间差异均具有统计学意义（P＜0.05）。结论 杭州地区老年人群男性与女性HbA₁c总体水平相似，各年龄组HbA₁c水平略有差异。依照2010年糖尿病诊断新标准筛查出糖尿病者疑似病例增多，为临床中糖尿病的早期发现提供了诊断指标。

Objective To investigate the distribution of glycosylated hemoglobin (HbA₁c) levels in senior populations in Hangzhou. Methods 1524 elderly people undergoing physical examinations in this hospital between January 2012 and June 2012 were recruited into this study. HbA₁c (%) levels were detected by an automatic glycated haemoglobin analyzer, and the results were statistically analyzed by gender and age. We also evaluated the 2010 new criteria for diagnosis of diabetes mellitus. Results The distribution of HbA₁c(%) levels was not significantly different in different gender groups, and the levels of HbA₁c(%) increased in 70-79 age groups. Conclusions The HbA1c levels in elderly people are similar among males and females but vary to some extent between different age groups. According to 2010 Guidelines, the number of patients with suspected diabetes mellitus has increased, making necessary early detection and early treatment of diabetes to reduce the incidence of diabetic complications.
