Prevalence of painful diabetic peripheral neuropathy and its impact on quality of life among diabetic patients in Western region, Saudi Arabia

Background: Diabetic neuropathy is the most common long-term complications of diabetes, frequently presenting as painful diabetic peripheral neuropathy (PDPN), which can significantly impair patients' quality of life (QOL). This study set to estimate the prevalence of PNPD and health-related quality of life (HRQoL) in the setting of primary health care in Saudi Arabia. Methods: This study was conducted in primary health-care centers affiliated with the National Guard Health Affairs in Western Saudi Arabia. Arabic version of the Douleur Neuropathique 4 questionnaire was administered on diabetic patients to screen for neuropathic pain and short-form 12 questionnaire to assess HRQoL. Results: The study screened (n = 349) Type 2 diabetic patients. The prevalence of PDPN was 33.2%. PDRN was more likely to affect females (adjusted odds ratio ["AOR"] =1.96, P = 0.024), and those living with diabetes for over 15 years (AOR = 2.26, P = 0.039), and those on insulin treatment (AOR: 2.33, P = 0.010) alone or in combination (AOR = 1.78, P = 0.034). Both physical and mental components (MCs) of QOL scores were significantly higher in diabetic patients without PDPN compared to those with it; 49.57 +/- 9.31 versus 40.77 +/- 8.14 for physical component QOL and 51.72 +/- 9.36 versus 44.35 +/- 8.12 for MC QOL, P < 0.001. Discussion and Conclusion: Painful peripheral neuropathy is relatively common among type 2 diabetic patients in Western Saudi Arabia and impacts both physical and MCs of the QOL of affected patients.
