| Objective The present study was designed to determine the relationships between sarcopenia and diabetic peripheral neuropathy(DPN)in patients with type 2 diabetes mellitus(T2DM)and diabetic foot disease(DFD)respectively.Methods A total of 1104 patients with T2 DM and 257 patients with DFD were included in the study,which was designed as a cross-sectional study.Body composition was assessed using Dual-energy X-rayabsorptiometry(DXA).The diagnosis of sarcopenia was based on the Baumgartner criteria.DPN was assessed by Neuropathy symptom score(NSS)and Neuropathy disability score(NDS),and the severity of neuropathy was divided into non-neuropathy symptom(NS),Mild NS,Moderate NS and Severe NS according to NSS.Logistic regression analyses were carried out to determine the relations of sarcopenia and DPN in patients with T2 DM and NSS in patients with DFD,respectively.Results The prevalence of DPN was 80.0% in T2 DM patients withsarcopenia and 70.3% in non-sarcopenia patients(P=0.007).Logistic regression analyses showed DPN was one of the independent risk factors for sarcopenia in T2 DM patients(OR 1.564 [95% CI: 1.004,2.435],P=0.048).The prevalence of DPN had no statistical significance in DFD patients with or without sarcopenia.However,the NSS of DFD patients with sarcopenia was higher than that of non-sarcopenia patients(P=0.032).In the multivariate logistic regression analysis,NSS was determined to be associated with sarcopenia in DFD patients(OR 1.387[95% CI: 1.074,1.789],P=0.012).The appendicular lean mass(ALM)of DFD patients without NS was higher than patients with mild,moderate and severe NS(20.71±2.73 vs 16.57±3.62 vs 17.99±3.54 vs 17.23±3.29 Kg,P=0.028).Conclusion DPN is an independent risk factor for sarcopenia in patients with T2 DM and NSS is also independently correlated with sarcopenia in patients with DFD,with the latter being more obvious with the aggravation of neurological symptoms in DFD patients. |
