[Objective] To evaluate the glycemic control and identifying factors for achieving such control in patients suffered from type 2 diabetes mellitus in Shanghai.
[Methods] A questionnaire survey and physical examination were conducted in patients with type 2 diabetes from 210 communities through a random sampling method. The criteria of American Diabetes Association (ADA) and China Diabetes Society (CDS), respectively, were applied to evaluate the control of glycemic, blood pressure and blood lipid. Logistic regression analysis was used to analyze factors for achieving the target goal of glycemic control (HbA1c<7.0%)recommended by ADA.
[Results] The mean HbA1c concentration of 1 624 patients with type 2 diabetes was 7.5%. Based on the recommended targets of CDS, 27.9% of the participants achieved the goal of HbA1c level less than 6.5%, whereas 5.1% of the participants achieved all three target goals of HbA1c level less than 6.5%, blood pressure less than 130/80 mmHg, and lowdensity lipoprotein cholesterol level less than 2.5 mmol/L. According to ADA, 43.6% of participants had a HbA1c < 7.0% and 9.9% of participants attained all three recommended targets (HbA1c<7.0%, blood pressure (BP)<130/80 mmHg, low-density lipoprotein cholesterol (LDL-C)<2.6mmol/L). Age, residence, disease duration, medical nutrition therapy (MNT)and waist-to-hip ratio (WHR) were influencing factors for achieving the HbA1c goal.
[Conclusion] The success rate of glycemic control was low in patients with type 2 diabetes mellitus in Shanghai. There are multifaceted determinants for achieving glycemic control.
