Abstract Background Despite having significant impact on the patient’s quality of life, painful diabetic peripheral neuropathy (PDPN) is usually underdiagnosed. Screening for PDPN in patients with diabetes is needed in order to get timely identification and management. Hence, the purpose of this study was to assess the prevalence and determinants of PDPN among diabetes patients attending outpatient at Jimma University Medical Center from September 1 November 10, 2019. Methods Hospital based cross-sectional study was conducted and douleur neuropathique-4 was used to identify the presence of PDPN. Data were collected using pretested structured questionnaire and entered into EPI data 3.1 and exported to SPSS version 20 for analysis. Both bivariate and multivariate binary logistic regression was employed to identify factors associated with PDPN. Variable having a p value of 0.05.
Clinical and behavioral characteristics of participants More than three fourth (80.1%) of participants were type 2 diabetes mellitus and majority of them were in normal BMI category. The mean duration of diabetes was 6.8 ± 5.3 years. Near to three fourth of the participants had controlled fasting blood sugar (≤130 mg/dl) (Table 2).
Prevalence of painful diabetic peripheral neuropathy In this study, the DN4 scores were used for defining prevalence of PDPN for each study subject. It was then defined as a score of ≥4 out of 10 DN4 screening questionnaire. Accordingly the prevalence of PDPN was 14.5% [95%CI:10.9–18].
Factors independently associated with painful diabetic peripheral neuropathy Diabetic patients who were currently active smokers were 6.17 times more likely to develop PDPN as compared with those who never smoker [AOR = 6.17; 95%CI: 2.25, 16.86]. Likewise, former smokers were 3.22 times more likely to develop PDPN as compared with those who never smoker [AOR = 3.22; 95%CI: 1.29, 8.03]. The other factor identified was diabetic duration. Participants of 5 to 10 years duration of DM were 3.32 times more likely to develop PDPN as compared with those who with less than 5 years duration of DM [AOR = 3.32;95% CI: 1.29,8.53]. Those participants of greater than 10 years duration were 8.86 times more likely to develop PDPN as compared with those with shorter diabetic history less than 5 years [AOR = 8.86;95% CI: 3.49,22.5] after controlling for other variables. Finally, diabetic patients with comorbid hypertension were 2.54 times more likely to develop PDPN compared to their counter parts [AOR = 2.54; 95%CI: 1.17, 5.49] (Table 3).
Discussion This study was intended to assess the prevalence and associated factors of PDPN. In the present study, the prevalence of PDPN among diabetic patients attending JUMC was 14.5% [95%CI: 10.9–18]. This study result was in line with several s
