Diabetic peripheral neuropathy in diabetic patients attending an urban health and training centre.

Introduction: Diabetic neuropathy is a complication affecting almost 50% of the diabetic patients. Diabetic Peripheral Neuropathy (DPN) predominantly affects the hands and lower limbs. It leads to loss of protective sensation resulting in continuous injury to insensitive feet. The early detection of DPN using an objective screening test followed by its appropriate management is important as up to 50% of the patients may be asymptomatic. Objectives: To screen Diabetic patients attending an Urban Health and Training Centre of a medical college in Tamilnadu for Diabetic Peripheral Neuropathy. To assess the association between DPN and selected variables such as socio-demographic factors, glycaemic control, duration of diabetes, physical activity, body mass index, smoking and consumption of alcohol. Methods: The study was conducted among 204 diabetic patients attending an Urban Health and Training Centre. Participants were assessed using Michigan Neuropathy Screening Instrument (MNSI), which involves using a questionnaire followed by a physical examination. Results: Of the 204 patients, 58.8% were male. The mean age was 54.8 years (SD = 8.8 years). About 79.9% were employed of which 29.4% were skilled labourers. Mean duration of diabetes was 6.2 years (SD = 5.3 years). The proportion of diabetics who screened positive for Peripheral Neuropathy was 23% and 45.6% using MNSI questionnaire and examination, respectively. An age of 60 years and above was significantly associated with DPN (OR = 2.505, Conclusion: A high proportion of diabetics with peripheral neuropathy did not express symptoms specific for diabetics. Thus, a simple tool like MNSI would be useful in primary care settings to screen for peripheral neuropathy, and hence prevent disability".
