不同营养评价方法对血液透析患者营养状况评价的比较

采用连续定点抽样，对162例血液透析患者在入院次日分别采用营养风险筛查2002（NRS-2002）和主观全面评定（SGA）法进行营养不良风险筛查。经NRS-2002筛查，150例血液透析患者的营养不良风险发生率为29．3％，SGA评定营养不良的发生率为41．3％，两种方法筛查结果之间的差异没有统计学意义（χ2=18．155，P=0．109）；依据BMI标准判定血液透析患者营养不足、超重和肥胖发生率分别为13．3％、30．7％和29．3％。NRS-2002和SGA均适用于血液透析患者营养不足的筛查，但NRS．2002在对患者的营养不良风险筛查中更为全面合理。

Comparison of Nutritional Risk Screening-2002 and Subjective Global Assessment in nutritional assessment for patients with maintenance hemodialysis

The nutritional status of 162 patients with maintenance hemodialysis （MHD） was screened by Nutritional Risk Screening 2002 （ NRS-2002 ） and assessed by Subjective Global Assessment （SGA） at the next day of admission. Among 150 MHD patients who met the study requirement, the nutritional risk was 29. 3% as screened with NRS-2002, and the rate of nutrition deficiency was 41.3% with SGA assessment, there was no difference between two methods （χ2 = 18. 155, P = 0. 109 ） ; According to BMI, the incidence of nutrition deficiencies, overweight and obesity in MHD patients was 13.3%, 30. 7% and 29.3%. NRS-2002 and SGA are applicable to nutritional deficiencies assessment in MHD patients, but NRS-2002 is more comprehensive and feasible than SGA.
