Neonatal Behavior and Social Behavior and Sensory Issues in 18 months Toddlers
Abstract
Background
There has long existed a need for early detection and early intervention for children with autism spectrum disorder. Accordingly, the aim of this study was to demonstrate, in a prospective manner, the relationship between behavioral features during the neonatal period and social behavior and sensory issues at 18 months.
Method
Participants were 105 full‐term infants considered “healthy” by an obstetrician. The behavioral features of the infants were evaluated using the Neonatal Behavioral Assessment Scale (NBAS) two–seven days after birth. Follow‐up assessments were conducted 18 months later using a Japanese version of the Modified Checklist for Autism in Toddlers (M‐CHAT‐JV) and the Infant/Toddler Sensory Profile (ITSP).
Results
Sixteen (15.2%) out of the 105 infants were M‐CHAT‐JV positive. There were significant differences between the M‐CHAT‐JV positive and M‐CHAT‐JV negative groups in two of the NBAS clusters: orientation and motor. We observed a significant negative correlation between the NBAS orientation cluster and the ITSP “low registration” and “auditory processing” sections, as well as between the NBAS motor cluster and the ITSP “sensation avoiding” and “tactile processing” sections. Logistic regression analysis showed that the NBAS orientation cluster and ITSP low registration were significantly associated with the M‐CHAT‐JV at 18 months.
Conclusion
The results suggest a relationship between the NBAS orientation cluster in full‐term neonates and their social behavior and sensory features at 18 months
