Abstract: | The Brazelton Neonatal Behavioral Assessment Scale (BNBAS) was administered to 61 full-term, healthy newborns between 7–10 days of age. Three groups of newborns made up the sample: 23 babies were born at planned home births to nonmedicated mothers, 22 were born in the hospital to nonmedicated mothers, and 16 neonates were born in the hospital to mothers who received obsteric medication. Analysis of variance indicated a significant F ratio on the BNBAS cluster for orienting behaviors; comparison of the BNBAS scores of the three groups revealed a significant difference on the BNBAS cluster for orienting behavior between the home-born babies and infants born in the hospital to mothers who received obsteric medication. There was no significant difference between groups for medication or birth setting alone, suggesting these perinatal factors have a complex, perhaps synergistic effect on newborn behavior. |
