Abstract
Background Diabetic peripheral neuropathy (DPN) is a common diabetic consequence that damages nerves and results in pain, numbness, and sensory loss. It has no known treatment, impairs mobility, and increases the risk of foot ulcers; therefore, early therapy is necessary. The objective of this study was to determine the factors associated with DPN in individuals with type 2 diabetes mellitus (T2DM). Methodology A cross-sectional study was conducted from July 2024 to December 2024 among 310 people who attended the diabetic outpatient department (OPD) of a tertiary care hospital in Chengalpattu district. The Neuropathy Disability Score (NDS), Neuropathy Symptom Score (NSS), and Morisky Medication Adherence Scale-8 (MMAS-8) were used, and data were collected and analyzed using IBM SPSS Statistics for Windows, V. 25.0 (IBM Corp., Armonk, NY, USA). Analytical tests such as the chi-squared test and odds ratio were used to find an association between DPN and its associated variables such as age, sex, glycated hemoglobin (HbA1c), and the duration of illness following which the enter method of logistic regression analysis was performed. Results Out of 310 participants, the prevalence of DPN was found to be present in 88 (28.4%). DPN was found to be significantly associated with education (adjusted odds ratio (AOR): 0.33, 95%CI: 0.15-0.74), marital status (AOR: 2.88, 95%CI: 1.52-5.47), comorbidities (AOR: 2.07, 95%CI: 1.05-4.08), and type of medication (AOR: 2.59, 95%CI: 1.29-5.21). Conclusion About 88 (28.4%) of people had DPN; those who were hypertensive and used insulin to control their DM were at a greater risk. Routine screening and control of blood sugar and blood pressure are essential for patients with DM.
