摘要
目的了解维持性血液透析(maintenance hemodialysis,MHD)患者营养状况及发生营养不良的常见膳食危险因素,为针对性营养干预提供依据。方法采用主观全面评定法(SGA)和营养不良风险筛查2002(NRS-2002)评估150例MHD患者的营养状态,同时采用连续3d24h膳食回顾法了解实际摄入内容,并进行必要的人体测量及营养生化指标检测。结果 4.00%(6例)的患者为C级,属重度营养不良;37.33%(56例)的患者为B级,属轻中度营养不良。29.33%(44例)的患者NRS-2002评分≥3分,存在营养不良风险。SGA和NRS-2002筛查结果差异无统计学意义(χ2=18.155,P=0.109)。单一指标营养不良的发生率为6%～75%。MHD患者的热能、蛋白质、脂肪和大部分维生素及矿物质摄入均明显低于膳食推荐摄入量(P<0.05)。单因素危险因素分析结果表明,透析时间和高龄与营养不良发生相关(P<0.05)。结论 MHD患者营养不良发生比例很高,热能和多种营养素摄入不足。透析时间和高龄可能是导致营养不良的重要原因。
Objectives To investigate the nutritional status of maintenance hemodialysis patients and analyze the diet risk factors of malnutrition.Methods Subjective global assessment（SGA） and nutritional risk screening 2002（NRS-2002） were used to evaluate the nutritional status of 150 patients undergoing maintenance hemodialysis,A 3-day retrospective 24-hour diet survey was carried out.Results SGA result showed that 6 patients（4.00%） were at C grade（severe malnutrition）,and 56 patients（37.33%） were at B grade（mild or moderate malnutrition）.NRS-2002 result showed that 44 patients（29.33%） were malnutritional risk with NRS-2002 score≥ 3.There was no significant difference between the two methods of screening results（χ2=18.155,P=0.109）.Biochemistry and somatometric measurement showed that the malnutrition incidence was 6%~75%.Food intake survey indicated that the intakes of energy,protein,fat and other nutrients were significantly lower in maintenance hemodialysis patients than in normal population（P0.05）.Age and dialysis duration was positively correlated with the incidence of malnutrition（P0.05）.Conclusion The incidence of malnutrition in maintenance hemodialysis patients is high,and the intakes of energy and other nutrients are insufficient.Age and dialysis duration maybe the important cause for malnutrition.
