A Comparison of the Decline in Glomerular Filtration Rate between Elderly Patients with Diabetes and those without Diabetes in Southwest China.

Objective: To investigate the effect of high blood glucose on the decline in the estimated glomerular filtration rate (eGFR) in the elderly.
Methods: We compared the decline in eGFR of diabetic and non-diabetic groups in the noninterventional state and analyzed the effect of hyperglycemia on the decline in eGFR among the elderly in a retrospective analysis of 1,223 cases of elderly people aged 65 years or older with a 4-year follow-up period.
Results: The prevalence of diabetes in the elderly increased significantly from 12.67% in 2017 to 16.68% in 2021. The rate of decline in eGFR in patients with diabetes was higher than in the population without diabetes, at 9.29% and 5.32%, respectively (both p <0.05).
Conclusion: The results of this study revealed that the prevalence of diabetes in the elderly increased significantly, and there is a more rapid decrease in the eGFR levels in those with diabetes than those without diabetes.
