Insights
Hand grip strength (HGS) is a reliable tool for assessing muscle power and nutritional status in children with chronic kidney disease (CKD). This bedside assessment aids in diagnosing protein energy wasting in pediatric CKD patients.
Area of Science:
- Pediatric Nephrology
- Nutritional Assessment
- Muscle Physiology
Background:
- Protein energy wasting (PEW) and cachexia are significant concerns in children with chronic kidney disease (CKD).
- Hand grip strength (HGS) is a validated measure of muscle power in adult CKD patients.
- Data on the utility of HGS for assessing muscle status in pediatric CKD is lacking.
Purpose of the Study:
- To evaluate the reliability of hand grip strength (HGS) as an indicator of muscle power.
- To determine the usefulness of HGS in assessing the nutritional status of children with CKD.
Main Methods:
- An observational cross-sectional study involving 73 children with CKD (45 with end-stage kidney disease on hemodialysis, 28 not on dialysis).
- Nutritional status assessed via biochemical markers (serum albumin, cholesterol) and anthropometrics (height, BMI).
- Body composition analyzed using a BCM device for lean tissue mass (LTM); muscle power measured by HGS.
Main Results:
- 69.8% of pediatric CKD patients exhibited HGS below the 10th percentile for age and sex.
- HGS was notably reduced in children with chronic renal insufficiency (CRI) and those with non-glomerular kidney disease causes.
- A positive correlation was found between HGS and height, but not with LTM or serum albumin.
Conclusions:
- Hand grip strength (HGS) serves as a dependable, accessible bedside tool for nutritional assessment in pediatric patients with chronic kidney disease (CKD).
- HGS can aid in the early identification of muscle wasting and malnutrition in this vulnerable population.
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.
