Birthweight curves for newborns according to maternal ancestry

Canadian data suggests that infants born to parents of East Asian and South Asian ancestry may be of lower birth weight than those of White European decent. Using traditional newborn birthweight curves, some Canadian newborns of East Asian and South Asian ancestry may be misclassified as small for gestational age birthweight (SGA), while they are actually normal in birthweight if compared to other East Asian and South Asian infants.
