Prevalence of peripheral diabetic neuropathy and its association with patients related factors

Aim: to determine the prevalence of peripheral diabetic neuropathy (pdn) in patients of type-2 diabetes and association of patient related variables with pdn. methods: this case control study was conducted in bakhtawar amin hospital multan. we included 110 patients of typer-2 diabetes within duration of 7 months (from nov-2016 to may-2017) in this study. diagnosis of pdn was made using previous history,physical examination and vibration perception test of the patients. we noted age,gender,bmi,hba1c levels,smoking history,diabetes duration and duration of diabetes in all patients. the data was analysed by using spss v23. association of age,duration of diabetes and bmi with pdn was compared student's t-test. moreover,association of gender and smoking history with pdn was compared using chi-square t-test. results: in our study,the prevalence of pdn was 51.8%. the mean age was higher in patients having pdn,56.43±6.96 years versus 48.42±6.18 years in patients without pdn (p-value <0.001). duration of diabetes mellitus was also prolonged in pdn patients 10.7±6.3 years versus 8.9±4.8 years in patients without pdn with p-value of <0.001. there were 43.90% patients belonging to lower class in pdn patients and only 15.10% patients were of lower class that did not have pdn. there were 45.30% patients belonging to upper class in non-pdn group and only 10.50% in pdn group (p-value <0.001). conclusion: patients age,duration of diabetes mellitus and socioeconomic status are independent predictors of the development of peripheral diabetic neuropathy in diabetic patients.
