Comparative StudyComparison of birth weight by gestational age between China and the United States.
To probe into the similarities and differences of birth weight by gestational age between China and the United States by a comparative study. ⋯ American white newborns were heavier than Chinese newborns. The differences were mainly due to race-specific influences, and were related to the differences in socioeconomic and educational background. We suggest that the references of birth weight by gestational age should be formulated separately in China and in the U.S.
