Abstract
Means of SD and smoothed percentiles of human fetal weight, length and head circumference at birth, and weight of the placenta between 26 and 44 wk of gestation are presented. Data are based on 5136 single and 208 twin, live-born newborn infants. Percentile curves differ considerably from those of the widely used Lubchenco curves. Fetal weight correction factors for maternal weight, parity and sex of the child are given. Among the various maternal and infantile variables influencing fetal growth, gestational age and maternal weight were the most significant ones affecting weight and length of the newborn. Parity and sex of the child were of moderate importance and, maternal height and nationality were of minor importance.
