    The study compared Chinese Newborn Growth Standards (CNGS) and INTERGROWTH-21st (IG-21) standards for predicting early childhood growth outcomes.

  • 2

    CNGS and IG-21 standards showed high agreement in birth weight classification, with a Kappa statistic of 0.856.

  • 3

    CNGS demonstrated superior predictive validity for identifying wasting and possible risk of overweight in infants and toddlers.

  • 4

    Small for gestational age (SGA) was significantly associated with wasting at 1 and 2 years based on CNGS, while IG-21 only showed this association at all ages.

  • 5

    The findings suggest that localized standards like CNGS may provide better applicability for assessing growth deviations in Chinese infants.
