我们进行了一项横断面和纵向研究，以评估生物阻抗指标（电阻，Rz;电抗，Xc;相位角，PA）是否反映了血液透析（HD）患者的营养状况，并承担与长期生存的显着相关性。将131例长期HD治疗患者的生物阻抗数据与272例年龄和性别匹配的健康对照者的生物阻抗数据进行比较。通过人体测量变量、血清白蛋白（SA）、标准化蛋白质分解代谢率（nPCR）和主观总体评估（SGA）评估营养状况。血液透析治疗后，三项生物阻抗指标均发生显著性变化，但除血液透析后的Xc外，其余均显著性差异（P
We carried out a cross sectional and longitudinal study to assess whether bioimpedance indexes (resistance, Rz; reactance, Xc; phase angle, PA) reflect the nutritional status of hemodialysis (HD) patients, and bear a significant association with their long-term survival. The bioimpedance data of 131 patients on chronic HD treatment were compared with those of 272 healthy controls matched for age and sex. Nutritional status was assessed by anthropometric variables, serum albumin (SA), normalized protein catabolic rate (nPCR), and subjective global assessment (SGA). All three bioimpedance indexes varied significantly with HD treatment, however, with the exception of Xc in post-HD, they were on average significantly (P
