Background: Peripheral neuropathy contributes to morbidity and mortality among diabetic patients. Objectives: We aimed to determine the prevalence of distal symmetrical polyneuropathy (DSP) and cardiovascular autonomic neuropathy (CAN) and their predictors among diabetic patients in Ilorin, North-central Nigeria. Materials and Methods: This was a cross-sectional study in which 175 consenting diabetic patients were recruited consecutively. We assessed DSP using the Michigan Neuropathy Screening Instrument (MNSI), and it was defined by MNSI symptom score ≥7 or physical examination score ≥2. CAN was assessed using five tests of cardiovascular autonomic function, and abnormalities in ≥2 tests defined CAN. Logistic regression analysis was used to identify the predictors of DSP and CAN. Results: The prevalence of DSP and CAN was 41.7% and 26.9%, respectively, while 19.4% had both. Hypertension (odds ratio [OR]: 2.401; 95% confidence interval [CI]: 1.169–4.930, P = 0.017) and poor glycaemic control (OR: 2.957; 95% CI: 1.488–5.878, P = 0.002) independently predicted DSP. Hypertension (OR: 2.215; 95% CI: 1.023–4.414, P = 0.043) and serum creatinine (OR: 1.035; 95% CI: 1.014–1.056, P ≤ 0.001) were independent predictors of CAN. Conclusion: DSP and CAN are common among diabetic patients, and thus efforts should be made to prevent their occurrence by intensifying blood pressure and glucose control while regularly monitoring renal function.
