Abstract
The purpose of this study was to examine the relationship between neonatal behavior and prenatal and perinatal risk factors in infants of teenage and older mothers in Puerto Rico and Mainland United States. The sample included approximately 300 newborn infants;half were examined in Puerto Rico, the other half in Florida, using the Brazelton Neonatal Behavioral Assessment Scale. Comparisons by maternal age and the number of obstetrical complications showed that for the Puerto Rican group, infants with fewer obstetrical complications were better able to regulate their crying and active states. Infants of teenage mothers with fewer complications had a higher level of arousal than infants of older mothers with fewer complications. Infant behavior in the Mainland sample did not vary by maternal age or complications. Multiple regression analysis indicated that the combination of biomedical variables significantly predicted neonatal behavior in both cultures. Mother's age was not separately correlated with neonatal behavior, but was repeatedly combined with other variables in the significant regressions. The findings suggest that infants of teenage mothers may differ from infants of older mothers, particularly in the organization of state behavior, and that the effects of maternal age on neonatal behavior are increased in the presence of biological outcome factors.
