Assessment of Nutritional Status in Children With Chronic Kidney Disease Using Hand Grip Strength Tool

Objective: Muscle status assessment is crucial for diagnosis of protein energy wasting PEW/cachexia in chronic kidney disease (CKD) population. Hand grip strength (HGS) has been used in muscle power assessment in adult CKD. However, no data is available about its usefulness in children with CKD. Hence, we aimed to study the reliability of HGS in reflecting the muscle power and thus, nutritional status in children with CKD. Design and methods: In this Observational cross sectional study we enrolled 73 CKD children; 45 had end stage kidney disease (ESKD) on hemodialysis (HD) and 28 had CKD but not on dialysis yet. Assessment of children's nutritional status was done through biochemical variables (serum albumin and serum cholesterol) and anthropometric measures (height and BMI). Body composition monitor (BCM) device was used for lean tissue mass (LTM) assessment whilst muscle power was tested by HGS tool. Results: The study showed that 69.8% of CKD patients had HGS values below 10th percentile for age and sex. Moreover, HGS was observed to be more affected in CRI patients and those with non - glomerular causes. HGS was also found to be positively correlated to height but not to lean tissue mass or serum albumin. Conclusion: HGS tool can be used as a reliable bedside tool for nutritional assessment in children with CKD. (C) 2018 by the National Kidney Foundation, Inc. All rights reserved.
