摘要 目的了解中老年维持性血液透析(MHD)患者营养状况,探讨与营养不良相关的因素,为临床早期发现,早期干预治疗,改善预后提供依据。方法采用主观全面营养评估(SGA)法,对在我院血液净化中心行规律MHD治疗3个月以上、尿素清除指数(Kt/V)>1.2、资料完整、年龄≥40岁的中老年慢性肾衰竭尿毒症期患者进行营养状况评估,并据SGA评估结果分为营养良好组(SGA1)、轻-中度营养不良组(SGA2)和重度营养不良组(SGA3)。采用单因素方差分析探讨与营养状况相关的因素。结果①MHD患者营养不良发生率:64例MHD患者SGA1为25例(39.06%),SGA2为33例(51.56%),SGA3为6例(9.38%),营养不良总发生率为60.90%。②与营养不良相关的因素:SGA3组的年龄显著高于SGA1、SGA2组(P<0.001和P<0.01);SGA3组Kt/V值显著低于SGA1、SGA2组(均P<0.001);SGA1、SGA2、SGA3三组间尿素减少率(URR)依次显著降低(P<0.001);SGA2、SGA3组外周血淋巴细胞总数(LC)均显著低于健康对照组(P<0.01);MHD患者血清白蛋白(ALB)均显著低于健康对照组(均P<0.001),SGA3组显著低于SGA2、SGA1组(P<0.05和P<0.01);SGA3组血清前白蛋白(PA)显著低于SGA1及健康对照组(均P<0.05);SGA1、SGA2、SGA3组体质量指数(BMI)及肱三头肌皮褶厚度(TSF)依次显著降低(均P<0.001),SGA3组显著低于SGA2组及健康对照组(P<0.01和P<0.001);MHD患者中臂围(MAC)、中臂肌围(MAMC)、手握力(HGS)均显著低于健康对照组(P<0.05、P<0.001或P<0.01),SGA1、SGA2、SGA3组MAC、MAMC依次显著降低(P<0.001),SGA3组HGS显著低于SGA1组(P<0.05)。结论中老年MHD患者营养状况普遍较差。年龄、ALB、PA、LC及人体测量学指标可作为评估营养状况的可靠指标,在一定范围内增加Kt/V及URR值,有望改善营养状况。
