Abstract
The effects of maternal alcohol use on mental development, growth, and dysmorphogenesis was studied in a sample of 1-year-old infants born to elderly primiparous mothers. Alcohol intake was measured using Jessor's AA score and a simple count of maximum number of drinks consumed in one day. Infant cognition was assessed using the Bayley Scale of Mental Development. Alcohol levels prior to, during, and following pregnancy were obtained. Alcohol intake was greatly reduced during pregnancy, returning to prepregnancy levels following birth. A significant linear relationship between drinking prior to pregnancy and infant mental development was found. The average mental development score of infants whose mothers consumed ≤3, 3.3 to 29.7, or ≥30 mL (≤0.10, 0.11 to 0.99, or ≥1.0 average fluid ounces) of absolute alcohol per day was 115, 108, and 95, respectively. Maximum number of drinks consumed in a day related to physical anomalies. No alcohol measure was significantly correlated with condition at birth, postnatal illness, or growth parameters of height, weight, and head circumference at 1 year. Deficits found were less pronounced than those reported in infants with fetal alcohol syndrome.
