Background: Diabetic peripheral neuropathy (DPN) is a significant microvascular complication of type 2 diabetes mellitus (T2DM), leading to considerable morbidity, including nonhealing foot ulcers and lower-limb amputations. Despite its impact, limited data are available on its burden and associated risk factors in rural populations. Objective: To estimate the prevalence of peripheral neuropathy among T2DM patients in a rural area of Chengalpattu district, Tamil Nadu, and identify associated risk factors. Materials and Methods: A community-based cross-sectional study was conducted among T2DM patients in rural Chengalpattu. Data were collected using a pretested semi-structured questionnaire, clinical examination, and validated tools like the Michigan Neuropathy Screening Instrument. Key demographic, clinical, and biochemical parameters were recorded. Logistic regression was used to identify risk factors associated with DPN. Results: Prevalence of DPN among the study participants was found to be 38.6%. Significant risk factors identified included age above 59 years, unmarried status, diabetes duration >8 years, and use of both insulin and oral hypoglycemic agents. Poor glycemic control (HbA1c >7.5) showed a positive association with DPN. Other contributing factors included the presence of comorbidities, obesity, smoking, and not inspecting feet regularly. Conclusion: The study highlights a high burden of DPN among rural T2DM patients in Chengalpattu district. The identification of modifiable risk factors such as poor glycemic control, prolonged duration of diabetes, smoking, and comorbid conditions underscores the importance of targeted screening and risk-reduction strategies. Integrating routine DPN screening into primary care and strengthening diabetes education and lifestyle modification programs can help prevent neuropathic complications.
