摘要
目的探索持续非卧床腹膜透析(CAPD)患者年龄与营养状况的关系,为营养教育提供指导。方法对2007年8月-2010年1月腹膜透析177例患者的临床资料进行回顾性分析,包括血红蛋白(HGB)、血清白蛋白(ALB)、年龄、体重指数(BMI)、腹膜平衡试验(PET)、尿素清除指数(Kt/V)、24h尿蛋白、腹透液漏出蛋白、标准化每日蛋白质分解率(nPCR)等,分析年龄与营养状况的关系。结果老年组(≥60岁)和中青年组(<60岁)ALB分别为(31.54±5.91)、(33.24±4.75)g/L,老年组ALB较低(P<0.05);老年组Kt/V值1.95±0.63和HGB水平(95.25±22.89)g/L均高于青年组(P<0.05)。两组患者营养不良与BMI、PET、每日蛋白漏出总量、nPCR无关。结论 CAPD老年患者(≥60岁)更容易发生营养不良,且老年组低蛋白血症与透析充分性无明显关系。故应加强老年CAPD患者的饮食营养管理指导,设计合理的饮食。
Objective To investigate the relationship between age and nutrition status of the patients undergoing continuous ambulatory peritoneal dialysis（CAPD）,and provide instructions for nutrition education.Methods We retrospectively analyzed the clinical data of 177 patients having undergone CAPD in the Department of Nephrology of West China Hospital between April 2007 and January 2010.Clinical parameters collected included hemoglobin（HGB）,serum albumin（ALB）,age,body mass index（BMI）,results of the peritoneal equilibrium test（PET）,urea clearance index（Kt/V）,24-hour urinary protein,protein loss in the peritoneal dialysate,normalized protein catabolic rate（nPCR）.Relationship between age and nutrition status in these patients were analyzed.Results Plasma albumin was（31.54±5.91） g/L and（33.24±4.75） g/L respectively in patients of or older than 60 years old（the elderly group） and in patients younger than 60 years old（the younger group）.Compared with the younger group,patients in the elderly group had lower ALB（P〈0.05）,but higher Kt/V 1.95±0.63 and hemoglobin level（95.25±22.89） g/L（P〈0.05）.In addition,malnutrition in both groups was not associated with BMI,PET results,daily protein loss in the peritoneal dialysate or nPCR.Conclusions Patients of or older than 60 years old undergoing CAPD are more likely to develop malnutrition,indicating that hypoalbuminemia is not associated with dialysis inadequacy.We advocate enhancing diet nutrition education in elderly CAPD patients and providing them with balanced diet regime
