Comparison of Chinese and international birth weight standards in predicting early childhood growth outcomes: a retrospective cohort study
To compare the Chinese Newborn Growth Standards (CNGS) and the INTERGROWTH-21st (IG-21) standards in terms of birth weight classification and their predictive performance for wasting and possible risk of overweight during infancy and toddlerhood.
Key Findings:
CNGS and IG-21 standards showed high agreement (Kappa = 0.856).
CNGS demonstrated higher specificity in predicting wasting and possible risk of overweight in infants and toddlers.
SGA was significantly associated with wasting at 1 and 2 years based on CNGS, while LGA was associated with possible risk of overweight at 2 years.
IG-21 standards showed significant association of SGA with wasting across all follow-up ages.
Interpretation:
CNGS demonstrated superior predictive validity for growth outcomes during infancy and toddlerhood, particularly for possible risk of overweight.
Limitations:
Conclusion:
CNGS offers greater applicability and superiority over IG-21 for early identification of growth deviations in Chinese infants and toddlers.
