Abstract: Type 2 DM is rapidly raising as a global health care problem that threatens to reach pandemic levels by 2030. Type 2 Diabetes mellitus is a disease with no cure and chronic disease that results in major morbidity and mortality. The main objective of this study is to evaluate the glyceated hemoglobin control and to determine factors affect on glycemic control among type 2 diabetes outpatients attending diabetic clinics at Hospital Universiti Sains Malaysia (HUSM). The study design was observational prospective longitudinal follow-up study, the study was conducted with sample of 1077 Type 2 Diabetes Mellitus outpatient recruited via attended the diabetes clinics at HUSM. HbA1c is parameter to measure the glyceated hemoglobin control. Logistic regression analysis was used to assess the independent variables that affect the glycaemic control. The majority of patients 794 (73.7%) did not achieve target of HbA1c levels ≤ 7.0%. It has been found that age, race and antidiabetic medications are the factors that affect on the HbA1c.New strategy to improve the current status of control of diabetes is needed. The study recommends that health-care providers should pay more attention to type 2 dm patients with older age, Malay race and antidiabetic medications.
