Factors Associated with Compliance Using Diamicron in Patients with Type 2 Diabetes

ABSTRACT

BACKGROUND: Diabetes mellitus (DM) is one of the most important chronic diseases in public health, thus optimal management of this condition is crucial. For this purpose, oral hypoglycemic agents (OHA) are commonly prescribed with their consistent use being mandatory to maintain adequate blood glucose levels. We aimed to evaluate the compliance with OHA in patients with DM, and to determine the factors associated with compliance. METHODS: From March 2006 to December 2007, we enrolled patients with type 2 DM who were newly diagnosed or had discontinued OHAs for more than four weeks. For OHA, diamicron was prescribed to the participants and response to medication was evaluated by physicians after 12 weeks. Compliance was defined as patients taking diamicron continuously or stopping the medication due to well-controlled blood sugar levels. Demographic characteristics, anthropometric measurements, fasting glucose, and lipid profiles were collected and analyzed. RESULTS: The mean age of our 326 subjects was 56.0+/-9.9 years and 74.5% was defined to be compliant. Logistic regression analysis adjusting for age and sex revealed that combined medication use (odd ratio [OR], 2.03; 95% confidence interval [CI], 1.04-3.97) and diabetes-related nutritional education (OR, 2.08; 95% CI, 1.08-4.03) (P<0.05) were factors associated with compliance with OHA. CONCLUSIONS: About three quarters of the DM patients in our study, using diamicron for the first time, showed compliance after 12 weeks of treatment. Concomitant medications and diabetes-related nutrition education were associated with compliance.
