Abstract
PURPOSE: To examine the relationship of diabetes-related foot disease (DFD) with diabetes and age-related complications in older patients with diabetes mellitus (DM). METHODS: We examined 562 outpatients with diabetes, aged ≥ 65 years, for DFD. The variables collected in this study were demographics, DM-related complications, treatment method, and age-related complications. Differences in the complications were compared between patients with and without DFD. Logistic regression analysis was used to determine the associations of DFD with DM and age-related complications. RESULTS: A total of 246 patients (43.8%) had DFD. Logistic regression analysis identified low grip strength [Odds ratio (OR): 1.83, 95% confidence interval (CI) 1.21-2.76), hypertension (OR: 1.81, 95% CI 1.09-3.00), and diabetes-related peripheral neuropathy (DPN) (OR: 1.92, 95% CI 1.24-2.98) to be significantly associated with DFD. Patients with DPN and hypertension had a higher risk of DFD than patients with DPN or hypertension alone. Individuals with DPN and low grip strength (OR: 1.74, 95% CI 1.09-2.81) were at a lower risk than those with low grip strength alone. CONCLUSION: Hypertension, DPN, and low grip strength were significantly associated with DFD in older patients with DM, with the risk of DFD being higher in patients with both DPN and hypertension. When considering DFD in older patients with DM, low grip strength should be considered equally important as a DM-related complication.
