Frequency and risk factors of abnormal nerve conduction studies in accidentally diagnosed diabetes

Abstract

Abstract Background Diabetic peripheral neuropathy (DPN) is one of the major diabetic complication and affects quality of life (QoL).This study aims at assessing the frequency of DPN among accidentally diagnosed diabetic patients, identifying risk factors linked to DPN in those patients, and determine the potential effect on QoL. Results According to nerve conduction study (NCS), 32 patients (44.4%) had polyneuropathy. Polyneuropathy is significantly associated with older age, higher hip and waist measurements, higher weight, and body mass index (BMI). About 53% of patients with polyneuropathy were current smokers versus 25% of non-smokers. Longer duration since the first diagnosis, higher fasting blood sugar (FBG), 2-h post-prandial (2-hPP) glucose, and HbA1c are also associated with peripheral neuropathy (PN) (p < 0.001). Being on insulin was associated with PN (p = 0.002). Increasing BMI, current smoking, and increased HbA1c significantly increase the risk of PN by 1.314, 19.963, and 3.302-folds, respectively. An unhealthy diet is also associated with PN.Hyperlipidemia was also associated with PN (p = 0.028). A significant positive association was found between DQoL scores and symptom scores. Conclusion A significant proportion of type 2 diabetic patients had DPN at the time of diagnosis, which adversely affects QoL. At the time of diagnosis, it is highly suggested that proper screening. procedures be used for DPN. Obesity, smoking, and elevated HbA1c significantly increase the risk of DPN.
