摘要
目的探讨持续非卧床腹膜透析(continuous ambulatory peritoneal dialysis,CAPD)患者的营养状况。方法随机选择病情稳定,符合观察条件的透析患者52例(男/女,32/20)。进行膳食营养评价、半定量SGA评分、人体测量以及生化指标检测。结果CAPD患者营养不良发生率高:以SGA评分作为评价指标,78.8%的患者有不同程度的营养不良;以ALB作为评价指标,67.3%的患者营养不良;基于AMC判断,则有55.8%的患者营养不良。营养摄入量与营养评价指标关系密切:DEI与BMI呈正相关(P<0.05),与ALB、PA呈正相关(P<0.05,P<0.01),而与SGA、CRP呈负相关(P<0.01,P<0.05);DPI与PA呈正相关(P<0.01)。蛋白质摄入充分组PA明显高于摄入不足组(P<0.01);热量摄入充分组ALB高于摄入不足组(P<0.05)。结论CAPD患者营养不良发生率高,膳食营养与CAPD患者营养状况密切相关,就维持血浆蛋白而言,摄入充足的热量可能比蛋白质更重要。
Objective To determine the nutritional status in continuous ambulatory peritoneal dialysis （CAPD） patients. Methods Fifty-two stable CAPD patients （male 32, women 20） were investigated. All patients were performed dietary survey, subjective global assessment （SGA） by semi- quantitative scale. Anthropometric measurements and their biochemical parameters including hemoglobin （HB）, serum albumin （ALB）, pre-albumin （PA） and C-reactive protein （CRP） as inflammation marker were measured. Results High prevalence of malnutrition 78.8%（41/52） in our CAPD patients was found based on SGA. However, on categorizing patients of malnutrition based on serum albumin, 67.3% （35/52） had malnutrition. By assessment based on AMC, 55.8% （29/52） had malnutrition. There was significant correlation between nutritional indices and dietary intake. DEI showed positively correlated with BMI （P〈0.05）, ALB （P〈0.05） and PA （P〈0.01）, and negatively correlated with SGA（P〈0.01） and CRP（P〈0.05）, However, DPI showed positively correlated with PA （P〈0.01）. Conclusion High prevalence of malnutrition is found in CAPD patients. Dietary intake is correlated with nutritional indices in CAPD patients. It is more important to have sufficient energy intake than protein intake.
