目的:探讨西宁市部分门诊患者就诊时血糖状况,分析其空腹血糖(FPG)和糖化血红蛋白(GHb A1c)间相关性。方法:选取我院2013年1月1—2013年6月30日同时化验FPG和GHb A1c的门诊患者1 541例,按就诊疾病及人群不同进行分类统计FPG和GHb A1c值,并检测两者的相关性。结果:患者FPG均值(8.7±4.5)mmol/L,≥7.0mmol/L占51.5%(794/1 541);GHb A1c均值(7.4±3.4)%,≥6.5%占45.6%(702/1 541)。糖尿病(DM)患者FPG和GHb A1c均值分别为(10.9±4.7)mmol/L、(9.2±3.4)%,非DM患者(6.2±2.5)mmol/L、(5.5±2.0)%,差异均有统计学意义(P<0.01)。DM患者FPG≥7.0mmol/L和GHb A1c≥6.5%分别为79.3%(635/801)和70.3%(563/801),非DM患者为21.2%(159/740)和18.8%(139/740),差异均有统计学意义(P<0.01)。FPG对GHb A1c总体相关系数(r)=0.64(P<0.01),DM患者r=0.49(P<0.01),非DM患者r=0.53(P<0.01),体检人员r=0.83(P<0.01)。结论:西宁市部分就诊人员血糖状况堪忧,以DM患者为甚;FPG和GHb A1c相关性在器质性疾病患者中不明显,而与体检人员中相关性较好。
Objective: To investigate the blood glucose status of some outpatients in Xining City at the time of diagnosis and analyze the correlation between fasting plasma glucose (FPG) and glycosylated hemoglobin (GHb A1c). Methods: A total of 1 541 outpatients with both FPG and GHb A1c were selected from January 2013 to June 30, 2013 in our hospital. The FPG and GHb A1c were classified according to the prevalence of disease and different groups. Correlation. Results: Mean FPG (8.7 ± 4.5) mmol / L, ≥7.0 mmol / L were 51.5% (794/1 541), mean GHb A1c was 7.4 ± 3.4%, ≥ 6.5% was 45.6% (702/1 541) ). The mean FPG and GHb A1c in patients with DM were (10.9 ± 4.7) mmol / L and (9.2 ± 3.4)%, respectively, and those in non-DM patients were 6.2 ± 2.5 mmol / L and 5.5 ± 2.0% Statistical significance (P <0.01). Patients with DM had FPG≥7.0mmol / L and GHb A1c≥6.5% with 79.3% (635/801) and 70.3% (563/801), respectively, with 21.2% (159/740) and 18.8% (139/740) with no DM ), The differences were statistically significant (P <0.01). The overall correlation coefficient (r) between FPG and GHb A1c was 0.64 (P <0.01), r = 0.49 (P <0.01) in DM patients and r = 0.53 ). Conclusion: The blood glucose status of some medical staff in Xining is very worrying, especially in patients with DM. The correlation between FPG and GHb A1c is not obvious in the patients with organic diseases, but the correlation with FPG is better.
