目的探讨非膳食因素对腹膜透析患者营养状态的影响。方法对50例腹膜透析治疗的患者使用主观综合营养评估法(SGA)及生化指标血红蛋白(Hb)、血清白蛋白(Alb)、总蛋白(TP)评估其营养状态,分析透析剂量、透析液葡萄糖浓度、腹膜炎发生次数、患者工作状态及学历水平等因素对腹膜透析患者营养状态的影响。结果透析液用量8L/d的患者以上4个指标虽均低于4～6L/d患者,但两者无明显差异(P>0.05);常规腹膜透析患者营养指标优于高糖透析患者(P<0.05);经常发生腹膜炎患者营养较差(P<0.01);正常工作及家务工作患者营养状况优于无工作患者(P<0.05),高学历患者优于低学历患者(P<0.05)。结论除膳食因素外,透析剂量、透析液葡萄糖浓度、腹膜炎发生次数、工作状态及学历水平等多因素相互作用,对腹膜透折患者营养状态有较大的影响。
Objective To investigate the effect of non-dietary factors on the nutritional status of peritoneal dialysis patients. Methods Fifty patients undergoing peritoneal dialysis were evaluated for nutritional status by subjective nutritional assessment (SGA), biochemical indicators of hemoglobin (Hb), serum albumin (Alb) and total protein (TP). The effects of dialysis dose, dialysate glucose Concentration, the number of peritonitis, the patient’s working status and academic level and other factors on the nutritional status of patients undergoing peritoneal dialysis. Results The dialysate dosage of 8L / d was lower than that of 4 ~ 6L / d patients, but there was no significant difference between the two indexes (P> 0.05). The nutritional indexes of routine peritoneal dialysis patients were better than those of high glucose dialysis patients (P (P <0.05). Patients with frequent peritonitis had poor nutrition (P <0.01). The nutritional status of patients with normal work and housework was better than those without work (P <0.05). Conclusion In addition to dietary factors, the dialyzing dose, the concentration of dialysate, the frequency of peritonitis, working status and educational level and other factors have a greater impact on the nutritional status of peritoneal patients.
