Insights
Early educational and family support services improved cognitive scores and reduced behavior problems in low-birthweight (LBW) preterm infants by age 3. These interventions show lasting benefits for at-risk children.
Area of Science:
- Developmental Psychology
- Pediatrics
- Public Health
Background:
- Low-birthweight (LBW) and preterm infants are at higher risk for developmental delays.
- Early intervention services are crucial for improving outcomes in vulnerable infant populations.
Purpose of the Study:
- To evaluate the efficacy of educational, family support, and pediatric follow-up services.
- To assess the impact of these interventions on cognitive and behavioral development in LBW, preterm infants.
Main Methods:
- Randomized clinical trial involving 985 LBW, preterm infants across 8 clinical sites.
- Intervention included educational and family support services plus pediatric follow-up during the first 3 years of life.
- Cognitive and behavior problem scores were assessed at 12, 24, and 36 months of age.
Main Results:
- Significant improvements in cognitive scores were observed at 24 and 36 months, persisting after controlling for baseline scores.
- Behavior problem scores were significantly lower in the intervention group compared to the follow-up group at 24 and 36 months.
- Intervention efficacy for behavior problems was greater in children with higher initial scores.
Conclusions:
- Early, targeted educational and family support services are effective in enhancing cognitive development and reducing behavioral issues in LBW, preterm infants.
- The timing and targeting of interventions are critical for maximizing benefits in disadvantaged children.
- Findings support the long-term value of comprehensive early intervention programs for at-risk infants.
Abstract:
The Infant Health and Development Program is a randomized clinical trial to test the efficacy of educational and family support services and pediatric follow-up offered in the first 3 years of life on reducing the incidence of developmental delay in low-birthweight (LBW), preterm infants in 8 clinical sites (N = 985). Effects of the intervention on cognitive and behavior problem scores over the 3 years are examined. Significant intervention effects were seen on cognitive scores at 24 and 36 but not 12 months of age; effect sizes were similar at both ages. These effects persist when controlling for earlier cognitive scores. At 24 and 36 months, behavior problem scores for the intervention group were significantly lower than for the follow-up group; the intervention was more efficacious for children with higher initial behavior problem scores. Results are discussed in terms of timing and targeting of services for LBW and disadvantaged children.
