EFFECTS OF ETHANOL-CONSUMPTION DURING PREGNANCY AND LACTATION ON THE OUTCOME AND POSTNATAL-GROWTH OF THE OFFSPRING

Although information about the pregnancy outcome of alcoholic mothers is relatively abundant, no information is available about the effects of ethanol consumption on the infant's postnatal growth. This investigation aims to describe the physical growth of 32 infants born to mothers accustomed to drinking pulque, a mild alcoholic beverage, on a daily basis during pregnancy and lactation and to quantitate the ethanol disposed through the milk, as well as to identify cases of newborns with fetal alcohol syndrome. No full-blown cases of the syndrome were found: birth weight was similar to their non-drinking counterpart, but the relative risk of newborns to drinking mothers to have a low birth weight was 3.39. Ethanol found in milk accounted for 40 mg/day available to the infant. The postnatal growth of infants of ethanol drinkers was similar to that of controls. Further studies on their mental development are required in order to understand the extent of the effects of such a habit.
