Abstract:
Objective:To analyze the mediating effects of self-efficacy and self-management behaviors on the relationship between depression symptoms and glycemic control among elderly patients with type 2 diabetes mellitus (T2DM), so as to provide references for optimizing health management of elderly T2DM patients.
Methods:T2DM patients aged ≥60 years from 8 community health service centers in Nanjing City were selected using a convenience sampling method. Basic information such as gender and age was collected through questionnaires. Depressive symptoms, self-efficacy, and self-management behaviors were assessed using the Patient Health Questionnaire, the Diabetes Self-Efficacy Scale, and the Diabetes Self-Management Behavior Scale, respectively. Glycated hemoglobin (HbA1c) was measured to evaluate glycemic control. A mediating effect model was constructed to analyze the mediating effects of self-efficacy and self-management behaviors on the relationship between depressive symptoms and glycemic control.
Results:A total of 567 elderly T2DM patients were included, with a median age of 70.00 (interquartile range, 7.50) years. There were 248 males (43.74%) and 319 females (56.26%). The median scores of self-efficacy, self-management behaviors, depressive symptoms, and HbA1c were 3.89 (interquartile range, 0.78), 4.45 (interquartile range, 1.55), 4.00 (interquartile range, 6.00), and 6.80% (interquartile range, 1.40%), respectively. The mediating effect analysis showed that depressive symptoms indirectly affected glycemic control among elderly T2DM patients through the independent mediating effects of self-efficacy (β=0.028, 95%CI: 0.016-0.043) and self-management behaviors (β=0.009, 95%CI: 0.003-0.016), as well as the chain mediating effect of both (β=0.025, 95%CI: 0.017-0.035). The mediating effects of self-efficacy and self-management behaviors accounted for 36.66% and 11.35% of the total effect, respectively, while the chain mediating effect accounted for 32.15% of the total effect.
Conclusion:Self-efficacy and self-management behaviors play mediating roles in the relationship between depressive symptoms and glycemic control among elderly T2DM patients.
