Introduction:

The type two diabetes is a chronic disease of great impact on public health. Its deficient clinical control is subject to poor medication adherence. Nephroprevention programs seek to improve the contro of this disease and an adequate adherence may be a strategy. The aim of this study was to determine the factors associated with medication adherence in patients with diabetes in the context of a nephroprevention program.

Materials and methods:

A cross-sectional study was conducted among 282 patients with type two diabetes mellitus from a nephroprevention program in the municipalities of Pasto and Túquerres in 2017; they were selected by a systematic stratified random sampling. The Morisky-Green test assessed adherence. Information was obtained from databases, medical records and through a structured questionnaire. A descriptive, bivariate analysis and a multivariate binary logistic regression for explanatory purposes were performed. The association measures were prevalence ratios (PR).

Results:

The median age of the participants was 67 years, 33 % were men and the proportion of adherence was 68 %. Factors that were independently associated with adherence were being a wo- man, PR: 1,25 (95% CI: 1,02-4,07), glycosylated hemoglobin between 6 %-6,9 %, PR: 1,66 (1,37-11,80), not using insulin PR: 1,36 (1,03-8,52), use of only metformin PR: 1,76 (1,76-10,15) and consultation by internal medicine, PR: 1,19 (1,19-4,78).

Conclusion:

The adherence to medication is influenced by multiple factors which not only depend on the patient, but also involve health professionals, the type of medication and its availability, as well as being associated with glycemic control
