Objective: To examine and compare the prevalence and risk factors for diabetic foot in the elderly and the younger adult patients Methods: Diabetic foot is defined as any foot pathology resulting from diabetes such as foot ulcer/ amputation, loss of protective sensation, peripheral vascular disease and foot deformities. A retrospective chart review based on the database of Thammasat University’s Center of Excellence for Diabetic Foot care (TU-CDC) was collected. The analysis covered diabetic patients, who received a comprehensive foot examination during the period from October 1, 2016 to September 30, 2017. The patients were divided into two groups; the elderly group (age ≥ 65 years old) and the younger group (age < 65 years old). Multiple logistic regression was used to explore independent risks of diabetic foot Results: Of the total of 469 patients, 463 were patients with type 2 diabetes, of which 227 patients were male. The mean age for the elderly group (n = 225) and the younger age group (n = 224) were 72.7 ± 0.4 and 53.9 ± 0.5 years old respectively. Diabetes duration and glycemic control were similar. The glomerular filtration rate was significantly less in the elderly. The elderly group had more prevalence of diabetic foot (48% vs 35%, p = 0.004). The most common diabetic foot abnormality in both groups were foot deformity. Adjusted analysis revealed that the elderly (OR 1.51, 95%CI 1.005-2.28), diabetic retinopathy (OR 2.10, 95%CI 1.40-3.15), disability (OR 1.96, 95%CI 1.01-3.81) and nail disorders (OR 1.89, 95%CI1.24-2.89) were independent risk of diabetic foot. However diabetes duration more than 10 years (OR 0.66, 95%CI0.45-0.98) is a protective factor against diabetic foot Conclusion: The elderly, diabetic retinopathy, disability and nail disorders are independent risk for diabetic foot. Therefore, all the elderly diabetic patients should receive a comprehensive foot examination and consultation/ education to prevent diabetic foot ulcer and subsequent amputation
