ABSTRACT
<p><b>OBJECTIVE</b>To explore the risk factors of diabetic peripheral neuropathy (DPN) and the relationship between DPN and diabetic retinopathy (DR).</p><p><b>METHODS</b>The data of the in-patients with type 2 diabetes mellitus (T2 DM) were retrospectively studied. A total of 200 T2 DM patients were divided into DPN group (n = 136) and non-DPN group (n = 64) according to peripheral neuropathy. The basic clinical data and the incidence rate of DR were compared between two groups. Logistic regression analysis was used to study the risk factors of DPN.</p><p><b>RESULTS</b>The course of disease, the level of BMI, glycosylated hemoglobin (HbA1c), 2 hour postprandial blood glucose (2 hPG), 2 hour glucose C peptide (2 hC-P) and the incidence rate of the DR were significantly different between two groups (P < 0.01). Logistic regression analysis showed that significant differences were observed in T2 DM complicated by DR (P = 0.023), the course of disease (P = 0.008), the level of HbA1c (P = 0.006), BMI (P = 0.000) and 2 hC-P (P = 0.065).</p><p><b>CONCLUSION</b>Diabetic retinopathy, the course of disease, the level of BMI,HbA1c and 2 hC-P are the risk factors for type 2 diabetic peripheral neuropathy. Diabetic peripheral neuropathy is positive correlated with diabetic retinopathy.</p>
