Prevalence and risk factors for peripheral neuropathy among type 2 diabetes mellitus patients at a tertiary care hospital in coastal Karnataka

Context and Objective: In view of the growing burden of type 2 diabetes mellitus (T2DM) globally and associated microvascular and macrovascular complications, the study was done to assess the prevalence and risk factors for diabetic neuropathy among T2DM patients attending a tertiary care hospital. Subjects and Methods: T2DM patients' ≥30 years of both gender, presenting to the Medicine Department at a tertiary care hospital were included in the study. Diabetic Neuropathy Symptom (DNS) questionnaire to assess symptoms and Diabetic Neuropathy Examination (DNE) scoring to assess clinical signs were used. Results: A total of 273 patients were included. The mean age was 57.8 ± 11.5 years. The male to female distribution was 75% (202) and 25% (71), respectively. According to DNS instrument, 41.4% patients scored positive for the presence of neuropathy while only 24.5% had neuropathy according to DNE score. The proportion of males affected by neuropathy was more than females. 43.1% males had a positive DNS score while only 27.2% of them had a positive DNE score. Duration of the disease was positively correlated with neuropathy. Neuropathy was more prevalent among people who had higher systolic and diastolic blood pressure as per DNS and DNE instruments. Conclusions: The present study identified a higher proportion of males to be affected by neuropathy. Hence, more detailed evaluation must be accorded to elderly male diabetic patients with longer duration of the disease. Lifestyle modifications and watchful screening need to be incorporated as part of routine patient health education during follow-up clinic visits.
