Depression influences the quality of diabetes-related self-management activities in elderly patients with type 2 diabetes: a cross-sectional study

摘要

Purpose: To evaluate the prevalence of depression and its impact on the quality of diabetes-related self-care activities in elderly patients with type 2 diabetes. Patients and methods: In this cross-sectional study, 184 patients with type 2 diabetes were enrolled. Depression was evaluated using Patient Health Questionnaire-9 while the quality of diabetes-related self-care activities was assessed using the Summary of Diabetes-Related Self Care Activities Questionnaire. Results: In our study group, 53.3% of the patients had moderate depression, 17.9% had severe depression, and 28.8% had no depression symptoms. Patient’s age ( P =0.024), presence of diabetic neuropathy ( P <0.001), and body mass index ( P =0.037) proved to be independent and significant predictors for developing depression in patients with type 2 diabetes. The severity of depression was reverse correlated with the quality of self-care activities for all the studied components: global score ( r =-0.305), diet intervention score ( r =-0.297), exercise score ( r =-0.388), glycemic monitoring score ( r =-0.055), and feet care score ( r =-0.180). The presence of severe depression was associated with an increased prevalence of diabetes complications such as diabetic neuropathy and chronic kidney disease. Conclusion: The prevalence of depression is higher in patients with type 2 diabetes compared to general population. Depression has a major negative impact on the quality of diabetes-related self-care activities and, being a treatable condition, proactive screening followed in case of a positive diagnosis by adequate treatment should be performed in all patients with diabetes.
