Polypharmacy is Associated with Diabetic Foot Ulcers in Type 2 Diabetes mellitus

A higher incidence of diabetic peripheral neuropathy may be associated with decreased sleep and increased depression in older adults

Aim: Diabetes mellitus (DM) tends to increase with aging. Nearly half of the patients with DM develop neuropathy (DPN). Despite its high burden and morbidity, the conditions that DPN may be associated with have not been adequately studied in older adults. We aimed to identify sleep duration and comprehensive geriatric assessment components that may be associated with DPN. Material and Method: This is a cross-sectional retrospective study. DPN diagnosed with a medical history, neurologic examination, and electromyography (EMG). 125 diabetic older patients were included. All comprehensive geriatric assessment tests and questions about sleep quality and time were performed. We divided the patients into two groups those without neuropathy and with neuropathy and compared them. Results: The median age of 125 patients was 72 (min-max; 64-94). 58.8% of them were women. The percentage of married people and living with their spouse and slept for 6 hours or more had a lower percentage in the DPN group. Polypharmacy and the percentage of heart failure were significantly higher in the DPN group. Lawton-Brody score, which shows instrumental daily living activities (IADL) and geriatric depression score (GDS) was higher in the DPN group. In logistic regression, we found that depression scores were higher and sleep duration was shorter in the DPN group (respectively, odd ratio:265 p:.012; odd ratio:.1.917 p:.045) Conclusions: DPN in older adults may affect the functionality and be associated with fewer sleep hours and depression. Not only blood glucose regulation but also other factors such as sleep duration and depressed mood may be associated with DPN in older adults.
