There is a lack of domestic and international clinical studies on the assessment of the hydration and nutritional status of children on dialysis by bioimpedance analysis-body composition monitor (BIA-BCM).


Children treated on dialysis in the nephrology department of the Children’s hospital of Fudan University between July 1, 2021 and December 31, 2022 were assigned. A total of 100 children were described before and after 3 days of their dialysis, including basic information, biochemical indicators, imaging findings, and BIA-BCM indicators, exploring the correlation between BIA-BCM indicators and clinical indicators.


Totally, 86 children with peritoneal dialysis and 14 children with hemodialysis were included. In peritoneal dialysis group, 19.77% and 36.05% had mild and severe water overload ; reduced LTI in 41.54% and increased LTI in 10.77%. In hemodialysis group, 35.71% with mild and severe water overload each; 3 cases with reduced LTI (Fig1).
There was a significant linear relationship between BIA-BCM hydration indicators and clinical hydration indicators, and BIA-BCM nutritional indicators and clinical nutritional indicators (Fig2).


BIA-BCM can help guide the adjustment of clinical treatment regimens, and chronic dialysis children have some degree of improvement in hydration and nutritional status.
