Learning Objective 1: The learner will be able to check the prevalence of type 2 diabetes mellitus treatment adherence

Learning Objective 2: The learner will be able to check the association between prevalence of type 2 diabetes mellitus treatment adherence and socio-demographic, clinical and metabolic control variables.

Purpose: to check the association between prevalence of type 2 diabetes mellitus treatment adherence and socio-demographic, clinical and metabolic control variables.

Methods: cross-sectional research, involving 423 Brazilian type 2 diabetes mellitus patients registered at 17 primary health care units in Passos, Brazil, in 2010. For data collection, instruments were used to assess socio-demographic, clinical and biochemical data and adherence to medication, diet and exercise. To check the association between treatment adherence and the study variables, Fisher’s exact test and logistic regression models were used, calculating the gross odds ratio with a 95% confidence interval for each variable in relation to the treatment adherence variable.

Results: only (1.4%) of patients demonstrated complete diabetes mellitus treatment adherence, considering medication, diet and physical exercise simultaneously. Total cholesterol and HbA1c showed a statistically significant association with diet (p=0.036) and physical exercise adherence (p=0.006), respectively.

Conclusion: the chance of diet adherence among patients whose total cholesterol levels remain within recommendations is almost five times as high as among patients with bad lipid control. The chance of physical exercise adherence among patients with bad glucose control is almost twice as high as among patients with adequate glucose control.
