Insights

Body composition assessment in children with bronchopulmonary dysplasia (BPD) is crucial for nutritional support. Both anthropometry and bio-impedancemetry showed limitations in precisely evaluating fat-mass and fat-free mass compared to DXA.

Area of Science:

  • Pediatric Nutrition
  • Body Composition Analysis
  • Respiratory Medicine

Background:

  • Children with bronchopulmonary dysplasia (BPD) frequently experience malnutrition and growth failure.
  • Accurate body composition assessment is vital for effective nutritional support in these children.

Purpose of the Study:

  • To compare the accuracy of bio-impedancemetry and anthropometry with dual-X-ray absorptiometry (DXA) for evaluating fat-mass (FM) and fat-free mass (FFM) in children with BPD.

Main Methods:

  • Seventy-one children aged 4-8 years with BPD were included.
  • Body composition (FM and FFM) was measured using anthropometry and bio-impedancemetry.
  • Measurements were compared against DXA using the Bland-Altman method.

Main Results:

  • Both anthropometry and bio-impedancemetry demonstrated reasonable agreement with DXA for FM and FFM assessment.
  • Anthropometry tended to slightly underestimate FM and FFM.
  • Bio-impedancemetry showed a tendency to overestimate FM and underestimate FFM.

Conclusions:

  • Neither anthropometry nor bio-impedancemetry can be reliably used for precise body composition evaluation in children with BPD aged 4-8 years.
  • Further research may be needed to refine these methods for pediatric BPD populations.
