Overweight in Pregnant Women and their Offsprings at Birth

The birth weight of a newborn is a significant determinant of neonatal and postnatal infant mortality. Maternal weight gain during pregnancy is one of the significant factors that influences on birth weight. Our purpose of this study is that to determine the effect of maternal eight gain on neonatal birth weight. This descriptive study is done on women who delivered in Mahdieh Hospital since Mehr 1376 to Azar 1377. The total of 354 women who delivered at term were included and following results were derived: The mean birth weight of newborns was 3260 gr and mean weight gain of mothers during pregnancy was 9.16 kg. In nulliparous women with increasing weight gain, the risk for low birth weight (birth weight 2500 gr) decreased and probability for high neonatal birth weight (birth weight 4000 gr) is increased (P < 0.0005) but this coordination was not present in multiparous women and result was not significant.
