Abstract:

Objective  To evaluate glycosylated hemoglobin A1c(HbA1c) control andits influencing factors in type 2 diabetic mellitus(T2DM) patients, and analyze the association of HbA1c control with diabetic complications. Methods    A cross-sectional study was carried out in 353 T2DM outpatients and inpatients from our hospital. A questionnaire interview was used by trained surveyors to collect data on general characters, self-management, therapy, complications, blood glucose and HbA1c. The patients were divided into group A (HbA1c＜6.5%) and group B(HbA1c≥6.5%). Results  ① Group A accounted for 22.1%. ②The prevalence rates of cerebrovascular diseases and diabetic retinopathy were significantly higher in group B than in  group A(P＜0.001,P=0.008, respectively). ③The rates of bloodglucose examination(≥4 times per month) and HbA1c examining(≥3 times per year) were 39.3% and 10.8% respectively, and only 5.8% of the patients accepted the above two mentioned examinations. The rates of patients who were knowledgeable about DM, controlled diet and took regular exercises were 35.4%, 31.4% and 53.1%,respectively. Conclusion  The present rate of good HbA1c control was low in T2DM patients, which can be associated with the occurrence of diabetic complications. The current situation of self-management is not satisfactory, so it is necessary to have more rigorous individual diabetic health education to improve HbA1c control, especially in the management of monitoring blood glucose, examining HbA1c, diet control and regular exercises.
