Infant’s Behaviour Checklist for low birth weight infants and later neurodevelopmental outcome

Evaluating the features of spontaneous movements and behavior in early infancy assists in estimating developmental outcomes. A recent study introduced the Infant Behaviour Checklist (IBC) and examined the relationship between the behavioural characteristics of low-birth-weight infants and neurodevelopmental outcomes at 6 years of age. The behavioural characteristics during the neonatal (36–43 weeks, adjusted) and early infancy periods (49–60 weeks, adjusted) were evaluated in very-low-birth-weight infants. The IBC contains 44 common behaviors.

The study evaluated the arrival of individual behavioural characteristics at each period according to the neurodevelopmental outcome. 

143 infants were assessed during the neonatal period, of which 89 showed typical development (TD), 30 showed intellectual disability (ID), and 24 showed autism spectrum disorder (ASD). 78 infants were assessed during early infancy, of which 40, 21, and 17 showed to have TD, ID, and ASD, respectively. The three behaviour-related items had a significantly lower frequency of appearance in the ID group than in the TD group. The three posture- and behaviour-related items had a significantly lower frequency of appearance, while of two posture-related items was a significantly higher frequency of appearance, in the ASD group than in the TD group. Behavioral assessment using the IBC may deliver promising clues when evaluating an early intervention for low-birth-weight infants.
