Transgenerational propensities for infant birth weight reflect fetal growth history of the mother in rhesus monkeys.

Birth weight (BW) at delivery is an important developmental milestone indicative of prenatal conditions and portends of the postnatal growth trajectory that will occur during infancy and childhood. Previous research has documented that there are also many physiological and health consequences of being born either small-for-gestational age (SGA) or large-for-gestational age (LGA). Analyses of breeding animals have demonstrated further that a gravid female exerts a strong influence on the size of her infant by term, and this permissiveness or constraint over fetal growth can be transmitted from mothers to their daughters.
