Differential classification of infants in United States neonatal intensive care units for weight, length, and head circumference by United States and international growth curves.

CONCLUSIONS: While Olsen and Fenton both fit, the Olsen curves had overall best-fit for our sample of US NICU infants. The INTERGROWTH-21st curves fit the definitions for SGA and LGA for younger ages, but inferences outside of these definitions are unwarranted due to limited sample size. The INTERGROWTH-21st sample used for 33 weeks and older infants was physically smaller at the upper percentiles than our sample of US infants. PMID: 32945183 [PubMed - as supplied by publisher]
