Insights
Children with intestinal failure often have abnormal body composition, even with normal growth. Routine body composition measurement is crucial for guiding nutrition interventions in these pediatric patients.
Area of Science:
- Pediatric Gastroenterology
- Nutritional Science
- Body Composition Analysis
Background:
- Previous studies linked abnormal body composition in pediatric intestinal failure to poor growth.
- This study focuses on body composition in normally growing children with intestinal failure.
Purpose of the Study:
- To report the body composition of pediatric patients with intestinal failure who exhibit normal growth.
- To identify potential risks for abnormal body composition in this specific patient group.
Main Methods:
- Retrospective analysis of 34 children (8-18 years) with intestinal failure undergoing dual-energy x-ray absorptiometry (DXA).
- Collected data included demographics, residual bowel anatomy, nutrition support, height, weight, bone mineral density (BMD), fat mass (FM), and fat-free mass (FFM).
- DXA data were compared with age- and sex-matched literature controls.
Main Results:
- Patients had normal height and weight z-scores but a mean BMD z-score of -1.0 ± 1.3, with 26% showing reduced BMD.
- Children with intestinal failure exhibited significantly higher fat mass (P = .02) and lower fat-free mass (P = .02) compared to controls.
- Abnormal body composition was observed despite normal growth parameters.
Conclusions:
- Children with intestinal failure are at risk for abnormal body composition, irrespective of normal height and weight.
- Routine body composition assessment is recommended for pediatric patients with intestinal failure.
- Body composition data can inform and direct tailored nutrition interventions.
Background:
Published reports on abnormal body composition in pediatric patients with intestinal failure have been in patients with poor growth. The goal of the current study is to report the body composition of normally growing patients with intestinal failure.
Methods:
Children 8-18 years old with a dual-energy x-ray absorptiometry (DXA) between January 1, 2013, and July 15, 2018, were included in the study. Data were retrospectively collected from the medical charts and included demographics, residual bowel anatomy, nutrition support, height, and weight. DXA data, including total body less head bone mineral density (BMD), fat mass (FM), and fat-free mass (FFM), were collected and compared with published literature controls matched for age and sex.
Results:
Thirty-four children met inclusion criteria. Mean age at the time of DXA was 9.6 ± 1.8 years. Weight- and height-for-age z-scores were -0.4 ± 0.9 and -0.5 ± 1.0, respectively. Mean BMD z-score was -1.0 ± 1.3. Twenty-six percent of patients (n = 9) had reduced BMD. Patients with intestinal failure had higher FM (P = .02) and lower FFM (P = .02) compared with controls.
Conclusions:
These data show that, despite reference range z-scores for height and weight, children with intestinal failure are at risk for abnormal body composition. Body composition should be routinely measured in children with intestinal failure to direct nutrition interventions.
