The relationship between minor physical anomalies and various areas of neonatal behavior was assessed in 120 full-term infants and 140 preterm infants. The anomalies consisted of those 18 described by Waldrop and Halverson. Neonatal behaviors included different aspects of activity level, irritability, soothability, and reactivity. Full-term male infants had significantly higher weighted anomaly scores than full-term female infants. No sex differences were found for the preterm group. Preterm females had significantly higher weighted anomaly scores than full-term females. No differences were found between full-term and preterm males. For the male full-term, female full-term, and male preterm infants, there was no more than a chance relationship between the weighted anomaly scores and the behavioral variables. For the preterm females, significant correlations indicated a relationship between weighted scores and high irritability and low reactivity. The results suggest that the application of anomaly scores is dependent on the sex and gestational age of the infant.
Key words: minor physical anomalies; newborn anomalies; anomalies and behavior.
