Relationship between glycaemic control and frailty in older Chinese patients: The mediating role of diabetes distress.

PURPOSE

This study aimed to investigate the effects of glycaemic control and diabetes distress on frailty in older Chinese patients with diabetes, and to explore the mediating role of diabetes distress between glycaemic control and frailty.

DESIGN

This is a descriptive, cross-sectional study. A total of 209 older patients with diabetes were recruited from a teaching hospital in Zhejiang Province. Data were collected from February to September 2022.

METHODS

A self-designed questionnaire was used to collect demographic and disease-related data. The Fried Scale and Diabetes Distress Scale were employed to assess frailty and diabetes distress, respectively The bootstrap method was used to examine the mediating effects of diabetes distress on glycaemic control and frailty. The STROBE checklist was adhered to in the reporting of this study (see details in File S1).

RESULTS

The findings indicated a positive correlation between the level of glycaemic control and frailty, as well as between diabetes distress and frailty. Furthermore, diabetes distress was found to play a complete mediating role between glycaemic control and frailty.

CONCLUSIONS

The study findings highlight the relationship between glycaemic control, diabetes distress and frailty offering a valuable reference for enhancing the management of frailty in older patients with diabetes.

RELEVANCE TO CLINICAL PRACTICE

This study emphasizes the significance of managing glycaemic control and diabetes distress in older patients with diabetes to prevent frailty, and may contribute for healthcare professionals to developing effective measures to improve the frailty of older diabetic patients in clinical settings.

PATIENT OR PUBLIC CONTRIBUTION

This study was conducted with the participation of older patients with diabetes who contributed data by completing study questionnaires and undergoing physical assessments.
