Abstract

Tittle. Prevalence of depression in adults with type 2 diabetes and associated factors

Introduction. People with type 2 diabetes can suffer psychological disorders such as depression, which affect their physical, mental, and emotional state.

Objective. The aim of this study to identify the prevalence of depression and factors associated with depressive symptoms in adults with type 2 diabetes.

Material and methods. Cross-sectional study in 155 adults with type 2 diabetes from Mexico City. Sociodemographic, anthropometric, clinical, diet and habits characteristics were evaluated. Depressive symptoms were measured with the Zung Self-Rating Depression Scale. Logistic regression analysis was performed.

Results. The prevalence of depressive symptoms was 29.7%. The associated factors were physical inactivity, living alone, a lower educational level, hypertension, hyperglycemia, and the duration of diabetes. The risk of having depressive symptoms was 2.1 (95% CI 1.0-4.7) with glucose values ≥130 mg / dL, 3.6 (95% CI 1.2-11) for hypertension, 3.5 (95% CI 1.3-9.5) when living alone and 2.9 (CI95% 1.3-6.4) due to physical inactivity.

Discussion. The factors associated with depression in patients with T2D were hyperglycemia, hypertension, longer duration of diabetes, a lower educational level and living alone. Blood glucose concentrations and longer duration of diabetes in years were the variables that explained a higher score for depressive symptoms.

Conclusions. Lack of recognition of depressive symptoms or late detection leads to complications of diabetes. These patients require adequate health education, with support to develop self-care and emotional adjustment strategies against depression.
