Adaptive Behavioral, Social-Emotional, and Neurodevelopmental Outcomes at 2 Years of Age in Hungarian Preterm Infants Based on Bayley III

ABSTRACT

Aim

 This study aimed to assess cognitive, language, and motor development as well as social-emotional and adaptive behavior skills of low birthweight (LBW) children.

Methods

Our cohort contained 305 two-year-old LBW children. Developmental functioning was assessed by the Bayley Scales of Infant and Toddler Development, 3^rd Edition.

Results

Performance in language, particularly in expressive communication was the poorest. Extremely low birthweight (ELBW) children were found to be at increased risk of developmental delay: 12.73 times in motor (95%CI = 2.8–57.5), 9.81 times in cognitive (95%CI = 3.2–29.6) and 3.91 times in language (95%CI = 1.6–9.4), and social-emotional skills (95%CI = 1.6–9.5). Parents of children with lower birthweight reported poorer social and practical adaptive skills. Self-care domain seemed to be the least developed.

Conclusion

Additionally, the screening for developmental delays, monitoring the adaptive behavior skills may also be useful – especially among ELBW children – in order to identify the specific areas, situations, and functions that are most in need of interventions.
