title: Knowledge of blood sugar control standard brings the higher attainment rate of HbA1c.
abstract: OBJECTIVE
  To analyze the important controllable factors which affect the glycemic control of diabetes.
  
  
  METHODS
  A cross-sectional study was carried out to examine the role of relevant characteristics in glycemic control by a sampling investigation of 430 diabetic patients in Hunan, China. A questionnaire was designed for personal interviews to collect data. Univariate regression analysis and multiple linear regression analysis were used to evaluate the effects of various factors on glycated hemoglobin A1c (HbA1c) control.
  
  
  RESULTS
  The level of HbA1c in 430 patients was (8.7±2.6)%, and the value in 34% patients among them was ≤ 7.0%. Base on univariate regression analysis some factors were associated with good HbA1c control, including age, diabetic education, self monitoring of blood glucose, knowledge of blood sugar control standard, living environment, and self-owned glucometer. However, the upgraded treatment was associated with poor control. Based on multiple linear regression analysis, the first four factors mentioned above were protective factors for HbA1c while upgraded treatment was risk factor for HbA1c.
  
  
  CONCLUSIONS
  Knowledge of blood sugar control standard, diabetic education and self monitoring of blood glucose are important controllable factors for better glycemic control of diabetes.
