This masterclass focuses on accurate pediatric nutritional assessment, growth monitoring, and interpretation of growth data. It covers essential measurements, corrected age, mid-parental height, MUAC, and appropriate use of pediatric growth charts. Participants will learn how to interpret growth trajectories and identify potential nutritional and growth concerns. The session also explores energy requirement calculations and disease-specific approaches for conditions such as prematurity, cystic fibrosis, diabetes, and SAM. Overall, it provides a practical clinical framework for accurate assessment, nutritional calculation, and long-term monitoring in pediatric care.
