Abstract:
Objective To investigate the association between nutrition and peripheral artery disease (PAD) in continuous ambulatory peritoneal dialysis (CAPD) patients.Methods One hundred and two stable CAPD patients from a single center were enrolled in this cross-sectional study.Automatic ankle-brachial index (ABI) measuring system was applied to examine ABI.Patients were divided into PAD group (ABI ＜ 0.9) and non-PAD group (ABI≥0.9).Clinical data were collected.Biochemical parameters were detected.Nutritional status was evaluated by serum albumin,handgrip strength (HGS) and subjective global assessment (SGA).Logistic regression analysis was performed to estimate the association of PAD with each nutritional marker as well as other potential risk factors.Results The incidence of PAD was 23.53％ (24/102).ABI was significantly lower in patients with malnutrition as compared to those without malnutrition [(0.72 ± 0.21) vs (1.04 ± 0.14),P＜0.01].Compared with non-PAD patients,serum albumin (P ＜ 0.01),HGS (P ＜ 0.01),diastolic blood pressure (P ＜ 0.05),serum creatine (P ＜ 0.05)、blood urine nitrogen (P ＜ 0.01) were significantly decreased,but age (P ＜ 0.01),the incidence of malnutrition [SGA,P ＜ 0.01],diabetic status (P ＜ 0.01),cardiovascular disease history (P ＜ 0.01) were significantly increased in PAD patients.Logistic regression analysis showed that serum albumin (OR=0.762,95％ CI:0.611-0.948,P=0.015),HGS (OR=0.988,95％ CI:0.979-0.997,P=0.013) were independent protective factors for PAD,malnutrition [(SGA),OR=21.101,95％ CI:5.008-88.901,P＜0.01] was independent risk factor for PAD in CAPD patients.Conclusions The PAD incidence of CAPD patients in our center is 23.53％.Nutrition is independent factor associated with PAD in CAPD patients.
