Anxious depression in patients with Type 2 Diabetes Mellitus and its relationship with medication adherence and glycemic control

ABSTRACT

A relationship between anxious depression has been proposed in patients with diabetes, which may contribute to the lack of medication adherence. The aim of this study was to investigate if there is a relationship between depression and / or anxiety with medication adherence and glycemic control in patients with type 2 Diabetes Mellitus (DM2). An analytical, cross-sectional study was carried out in the internal medicine outpatient clinic of a Hospital in Mexico. Patients with DM2 participated over a period from November 2015 to January 2016. The Morisky scale for medication adherence, and the Goldberg anxiety and depression scale were conducted for each patient. Data was collected from a total of 179 patients. There was a significant difference between anxious depression and medication adherence (p < 0.001) using logistic regression with an R² of 0.136. There was also a significant difference between anxiety and glycemic control (p < 0.001) with an R² of 0.175, however no significant difference was found between glycemic control and anxious depression. Our findings demonstrate that patients who suffer from anxious depression also tend to have reduced medication adherence, and anxiety was associated with poor glycemic control in patients with DM2 within the Mexican population.
