Association of diabetes mellitus with depression, anxiety and quality of life

"Introduction: Many studies demonstrated that psychological factors play an important role in the development and course of diabetes mellitus. Objective: The focus of our research, among the first in a Hungarian sample, was to examine depression and anxiety levels and diabetes-specific quality of life in people with type 2 diabetes, to explore gender differences, and to analyze the relationship of depression and anxiety with diabetes-specific quality of life. Method: 157 people diagnosed with type 2 diabetes (women: 58.6%, men: 40.1%) were assessed for levels of depression Center for Epidemiologic Studies Depression Scale – Hungarian version), anxiety (Spielberger’s Trait Anxiety Questionnaire) and diabetes-specific quality of life (Audit of Diabetes-Dependent Quality of Life – Hungarian version). Results: 65% of subjects did not show depressive symptoms, but 56.1% showed moderate trait anxiety. More severe depressive symptoms (U = 1625, p<0.001) and higher trait anxiety (U = 1556, p<0.001) were significantly more frequent in women compared to men. Depressive symptom severity and trait anxiety were inversely and weakly correlated with diabetes-specific quality of life. Discussion: In summary, the results suggest that the psychological state (depressive symptoms and anxiety) in patients with type 2 diabetes is associated with their diabetes-specific quality of life. Women with diabetes also have higher levels of depression and anxiety compared to men with diabetes. Conclusion: Psychological assessment of patients’ depressive and anxiety symptoms and quality of life is recommended in the care of diabetic patients, and appropriate treatment is recommended as needed. This may improve patients’ quality of life, therapeutic cooperation and disease prognosis."
