To determine the effect of using customized vs. standard population birthweight curves to define large for gestational age (LGA) infants.We analyzed data obtained from 2,097 singleton pregnancies three different methods classifying newborn birthweight: curves, British or Spanish curves. We recorded maternal characteristics, proportion LGA newborns when each method, percentage according one method but not others, and concordance between methods.The was significantly lower than that calculated either general (p < 0.001). A third (33.9%) infants classified as were adequate (AGA) used, 18.5% non-LGA Concordance models high, on excluding AGA coefficient low (Cohen's κ <0.4).The use allows differentiation constitutional cases fetal overgrowth, leading a decrease in rate both false-positives negatives well overall babies.
