摘要

Impact

Body composition estimates in infancy differ substantially depending on the tool used (ADP, DXA, or BIA) and on within-tool factors (e.g. DXA software version).

This study systematically compares three widely used infant body composition tools, demonstrating that the choice of tool and analysis approach can markedly affect the results.

These findings underscore the need for caution when comparing infant body composition measurements across studies or over time where a change in tool type has been required.

Standardized protocols and transparent reporting will be crucial for improving paediatric nutrition and growth assessments.
