Trajectories of problem behaviors from 4 to 23 years in former preterm infants

Area of Science:

• Developmental Psychology
• Pediatric Neurology
• Behavioral Science

Background:

• Premature infants face increased risks for later behavioral issues.
• Understanding long-term behavior trajectories is crucial for early intervention.
• Neonatal factors, gender, and socioeconomic status (SES) may influence these trajectories.

Purpose of the Study:

• To examine the growth trajectories of externalizing, internalizing, and attention problem behaviors in premature infants.
• To investigate the influence of neonatal risk, gender, and SES on these developmental pathways.
• To provide insights for timely assessment and intervention strategies for clinicians.

Main Methods:

• Longitudinal study of 160 preterm infants (birth weight 640-1950g) with varied neonatal morbidity.
• Behavioral data collected at five developmental points from age 4 to 23 years using the Child Behavior Checklist.
• Latent growth curve modeling used to analyze developmental trajectories and influencing factors.

Main Results:

• Significant individual variation observed in externalizing and internalizing problem behaviors over time.
• Males consistently scored higher on externalizing problems, with no significant gender difference.
• Neonatal risk predicted higher internalizing problems at age 4 but not later; attention problems increased in males through adolescence.

Conclusions:

• Behavioral trajectories in preterm infants are complex and vary individually.
• Early neonatal risk has a limited long-term impact on behavior, with gender influencing specific patterns.
• Findings support the need for ongoing behavioral monitoring and tailored interventions for preterm populations.
