目的 采用动态血糖监测(CGM)技术探讨不同糖代谢人群24 h平均血糖水平(MBG)与糖化血红蛋白(HbA1c)的关系,并初步建立不同HbA1c水平其相对应的MBG值.方法 选取2007年8月至2010年1月于上海交通大学附属第六人民医院门诊及病房进行口服葡萄糖耐量试验(OGTT)的受试者318人,其中正常糖调节组115名、糖调节受损组57例、新诊断2型糖尿病患者组146例.糖尿病、糖调节受损的诊断采用2003年美国糖尿病学会(ADA)糖尿病诊断标准.测量各组生化指标,并行OGTT,测定糖负荷后2 h血糖(2 h PG).采用CGM系统估算MBG水平,高压液相法测定HbA1c水平,分析MBG与HbA1c间的关系.统计学采用单因素ANOVA方差分析、Kruskal-Wallis检验、χ^2检验、Spearman相关分析及线性模型进行数据统计.结果 318例研究对象中总体HbA1c水平为(6.6±1.5)%,MBG水平为(7.3±2.3)mmol/L.(2)MBG与HbA1c呈显著正相关(r=0.848,P〈0.01),其回归方程为MBG=1.252×HbA1c-0.992(R^2= 0.718,P〈0.01),即HbA1c每升高1%,MBG相应升高1.252 mmol/L.HbA1c=6.5%时,对应的MBG值为7.1 mmol/L.HbA1c=7.0%时,对应的MBG值为7.8 mmol/L.(3)仅包括146例新诊断2型糖尿病患者的MBG和HbA1c之间的关系与总人群的结果一致(r=0.788,P〈0.01),线性回归方程为MBG=1.255×HbA1c-0.886(R2=0.621,P〈0.01).当HbA1c= 6.5%时,MBG对应值为7.3 mmol/L.HbA1c=7.0%时,对应的MBG值为7.9 mmol/L.结论 初步建立了各HbA1c水平其相应的MBG值,为深入开展中国人群平均血糖与HbA1c转换关系研究提供了线索. 相似文献

Until 2010, the diagnosis of diabetes mellitus was based solely on glucose concentration, but the American Diabetes Association (ADA) recommendations now include a new criterion: hemoglobin A1C ≥6.5%. Because this change may have significant implications for diabetes diagnosis, we conducted a comprehensive literature review including peer-reviewed articles not referenced in the ADA report. We conclude that A1C and plasma glucose tests are frequently discordant for diagnosing diabetes. A1C ≥6.5% identifies fewer individuals as having diabetes than glucose-based criteria. Convenience of A1C test might increase the number of patients diagnosed, but this is unproven. Diagnostic cut-points for both glucose and A1C are based on consensus judgments regarding optimal sensitivity and specificity for the complications of hyperglycemia. A1C may not accurately reflect levels of glycemia in some situations, but in comparison with glucose measurements, it has greater analytic stability and less temporal variability. When choosing a diagnostic test for diabetes, the limitations of each choice must be understood. Clinical judgment and consideration of patient preference are required to appropriately select among the diagnostic alternatives. 相似文献

Diabetes mellitus (DM) is a frequent disorder affecting individuals of all ages. Glycohemoglobin has a key role in the assessment of glycemic control in diabetic patients. Several studies have clearly shown that improved glycemic control is strongly associated with decreased development and/or progression of diabetic complications. The chemical reaction of glycosylation in formation of hemoglobin A1c (HbA1c) has been described for decades. Here, the author performed a reappraisal on the bonding energy based on quantum chemical analysis. The author calculated the bonding energy of the reaction and found that the reaction is a type of “energy-consuming reaction.” In addition, the author gives further implication of the findings on the poor-control DM patients. The author hereby proposed that the nature of energy-consuming reaction in formation of hemoglobin A1c (HbA1c) is a main underlying for the energy loosing in poorly controlled DM patients. Gathering of the energy from the nearby cellular compartment during formation of HbA1c might be an important pathological process. 相似文献

We analyzed data of 35,624 non-diabetic Koreans using fasting plasma glucose (FPG) criteria and HbA1c criteria in screening for diabetes. Among the 1,491 subjects newly diagnosed with diabetes, 473 (31.6%) met the FPG criteria only (≥7.0 mmol/l), 350 (23.5%) met HbA1c criteria only (≥6.5%), and 668 (44.9%) met both criteria. The DM-by-HbA1c group had significantly older age, higher proportion of women, and lower hemoglobin concentration. The DM-by-FPG group had higher systolic and diastolic blood pressure, fasting serum insulin, and HOMA-IR. Further studies are needed to determine which of these criteria is superior in predicting the risks of long-term vascular complications of diabetes. 相似文献

Aims/Introduction: Although several risk factors for type 2 diabetes have been identified, most of them have been identified in studies on Western populations, and they should be evaluated in a Japanese population. In 2010, new diagnostic criteria for diabetes mellitus using hemoglobin A1c (HbA1c) were released and its use in epidemiological studies has many advantages. The aim of the present study was to evaluate risk factors for type 2 diabetes defined based on HbA1c values in a Japanese population. Materials and Methods: A total of 9223 subjects (3076 men and 6147 women) were followed up for 5 years. Diabetes was defined based on self‐report or HbA1c value. Risk factors for diabetes were evaluated as odds ratios adjusted for potential confounding factors by logistic regression. Results: During the 5‐year follow‐up period, we documented 518 incident cases of diabetes (232 men and 286 women). Of the 518 incident cases, 310 cases were diagnosed by HbA1c alone. Among the men, age, smoking (both past smoking and current smoking) and family history of diabetes significantly increased the risk of diabetes. Among the women, body mass index, family history of diabetes and hypertension significantly increased the risk of diabetes. These results did not change markedly after adjustment for the baseline HbA1c values, and the baseline HbA1c value itself was a significant risk factor for diabetes mellitus. Conclusions: Known risk factors for diabetes established in Western populations also increased the risk of diabetes in a Japanese population defined on the basis of HbA1c values.
