Insights
Energy needs in children with spastic cerebral palsy (CP) increase with age. Resting energy expenditure (REE) and total energy expenditure (TEE) correlate with body composition, with height-based estimation proving practical for nutritional assessment.
Area of Science:
- Pediatric Nutrition
- Clinical Metabolism
- Cerebral Palsy Research
Background:
- Accurate energy requirement estimation is crucial for children with cerebral palsy (CP).
- Optimizing energy intake supports growth and development in pediatric CP populations.
Purpose of the Study:
- To investigate the relationship between resting energy expenditure (REE) and total energy expenditure (TEE) with age, anthropometry, and body composition in children with spastic CP.
- To validate height-based energy expenditure estimation as a practical method.
Main Methods:
- Cross-sectional study of 79 children with spastic CP (24 months to 16 years).
- Bioelectrical impedance analysis used for body composition and energy expenditure assessment.
- Statistical analyses included ANOVA, post hoc tests, and Pearson correlation.
Main Results:
- Significant increases in REE and TEE (kcal/d) observed with increasing age.
- Strong positive correlations found between REE/TEE and fat-free mass (FFM) and fat mass (FM).
- FFM, total body water, and FM significantly explained variability in energy expenditure.
Conclusions:
- Energy expenditure in children with CP increases with age.
- Height-based energy expenditure (kcal/cm/d) estimation is consistent across age and sex.
- Height-based estimation offers a practical and reliable method for assessing energy needs and ensuring adequate nutritional status in children with CP.
Introduction:
proper estimation of energy requirements in children with cerebral palsy (CP) is essential in ensuring that their energy needs are optimally met.
Objective:
therefore, the purpose of this study was to demonstrate that resting energy expenditure (REE) and total energy expenditure (TEE) are associated with age, anthropometric indicators and body composition in children with spastic cerebral palsy.
Methods:
a cross-sectional study included 79 participants with spastic CP from 24 months to 16 years nine months. Weight and height (estimated by lower leg length) were obtained; body composition and energy expenditure were estimated by bioelectrical impedance analysis. ANOVA, post hoc tests, the Pearson correlation and determination coefficients (R2) were performed.
Results:
significant gradual increases according to age in REE and TEE (both in kcal/d) were observed. There were highly significant positive correlations between REE and TEE (kcal/d, kcal/cm/d) with fat-free mass (FFM) and fat mass (FM), but negative correlations between REE (kcal/ kg/d) with body composition and energy indicators. FFM and total body water, and to a lesser extent FM, explained a high percentage of the direct variability of REE and TEE in kcal/d and the inverse in kcal/kg/d.
Conclusions:
as age increased, energy expenditure also increased. The estimated energy expenditure in kcal/cm/d did not differ with age and sex. The estimated energy expenditure, based on height, would be a practical and reliable method for estimating energy expenditure and ensuring adequate nutritional status.
