腹膜透析患者营养状态改变时体成分的变化

Variety of body composition when nutrition status changes in patients under continuous ambulatory peritoneal dialysis

目的探讨连续不卧床腹膜透析(continuous ambulatory peritoneal dialysis,CAPD)患者营养状态改变时体成分的变化。方法采用回顾性队列研究的方法,选取在我中心治疗,经主观综合性营养评估(subjective globalassessment,SGA)由SGA-B转为SGA-A,且在营养评估同时有体成分测量数据的患者共31例。观察CAPD患者营养状态转变后体成分的变化。结果患者由营养不良到营养好转体质量由(59.55±11.25)kg增加至(61.04±11.67)kg(P>0.05),脂肪量由(17.72±9.80)kg增加至(19.62±11.19)kg(P<0.05),内脏脂肪由8.48±3.90增加至10.00±3.97(P<0.01),而瘦体质量、肌肉量、体水分量、骨骼量差异无统计学意义(P>0.05)。结论CAPD患者营养状态改变时体成分会发生明显的变化,即随着营养状态的好转,体内脂肪量及内脏脂肪会明显增加。

Objective To investigate the variety of body composition when the nutrition status changes in the patients under continuous ambulatory peritoneal dialysis （CAPD）. Methods A retrospective cohort study was conducted in 31 CAPD patients who had a nutrition status transition from SGA-B to SGA-A, bioimpedance analysis （BIA） was employed to assess the body composition in evaluating the nutrition status. Results When matnutrion was improved,the body mass would increase from （59.55±11.25） kg to （61.04±11.67） kg（ P 〉0.05） ,body fat would increase from （17.72±9.80） kg to （19.62±11.19） kg（ P 〈0.05） ,and the visceral fat would increase from 8. 48± 3.90 to 10.00±3.97（ P 〈0.05） ,but there were no difference in lean body mass,muscle,total body water,and bone（ P 〉0. 05）. Conclusion There are differences of body composition between different nutrition statuses of CAPD patients; Body fat and visceral fat increase dramatically when patients transfer to a good nutrition condition.
