The nutritional status and influencing factors of peritoneal dialysis patients

Objective To investigate nutritional status and influencing factors of continuous ambulatory peritoneal dialysis(CAPD) patients.Methods Forty cases of CAPD admitted to our hospital from July 2009 to 2011 July enrolled the study.Subjective global nutritional assessment(SGA) was used to evaluate the nutritional status of patients.According to the nutritional status,the patients were divided into normal nutrition group,mild to moderate malnutrition group,and severe malnutrition group.Serum creatinine(Scr),albumin(ALB),prealbumin(PA),C-reactive protein(CRP),carbon dioxide combining power(CO2CP),cholesterol(CH),and peritoneal transport characteristics were determined and compared among the three groups.Results Determination of nutritional status of 40 CAPD patients were normal nutrition in 25(62.5%),mild to moderate malnutrition in 10(25.0%),and severe malnutrition in 5(12.5%).There were significant differences in the levels of Scr,ALB,PA,CRP,CO2CP,and CH among the three groups(P0.05).Of 25 patients with normal nutrition,low transport and low average transport were found in 22(88%);of 15 malnourished patients,the high transport and high average transport were found in 13(86.67%)(P0.01).Conclusion The occurrence of malnutrition in CAPD patients is very high,and the peritoneal transport type of malnutrition patients mostly belongs to the high transport and high average transport type.Scr,ALB,PA,CRP,CO2CP and CH are important factors of nutritional status in CAPD patients.The correction of these factors may help to improve the nutritional status of patients.
