Paper doi abstract bibtex CONTEXT: The outcome into school age of regional cohorts of children born in the 1990s with birth weights less than 1000 g (extremely low birth weight, ELBW) or earlier than 28 weeks' gestation (very preterm) is not known. OBJECTIVE: To determine the cognitive, educational, and behavioral outcome of ELBW or very preterm infants born in the 1990s compared with normal birth weight (NBW) controls. DESIGN: Regional cohort study. SETTING: Victoria, Australia. PARTICIPANTS: The ELBW or very preterm cohort was composed of 298 consecutive survivors born during 1991-1992. The NBW cohort was composed of 262 randomly selected children with birth weights of more than 2499 g. MAIN OUTCOME MEASURES: Cognitive ability, educational progress, and behavioral problems. RESULTS: The follow-up rates from birth to 8 years of age for survivors were 92.3% (275/298) for the ELBW or very preterm cohort and 85.1% (223/262) for the NBW cohort. The ELBW or very preterm children scored significantly below NBW controls on full-scale IQ (mean difference, -9.4; 95% confidence interval [CI], -12.1 to -6.7; P\textless.001) and indices of verbal comprehension (mean difference, -6.8; 95% CI, -9.5 to -4.2; P\textless.001), perceptual organization (mean difference, -9.9; 95% CI, -12.7 to -7.2; P\textless.001), freedom from distractibility (mean difference, -8.1; 95% CI, -10.8 to -5.5; P\textless.001), and processing speed (mean difference, -6.7; 95% CI, -9.4 to -4.0; P\textless.001). The ELBW or very preterm children performed significantly worse than the NBW cohort on tests of reading (mean difference, -6.7; 95% CI, -9.5 to -3.9; P\textless.001), spelling (mean difference, -5.6; 95% CI, -8.0 to -3.3; P\textless.001), and arithmetic (mean difference, -8.8; 95% CI, -11.3 to -6.2; P\textless.001). Attentional difficulties, internalizing behavior problems, and immature adaptive skills were more prevalent in the ELBW or very preterm cohort. CONCLUSION: School-aged ELBW or very preterm children born in the 1990s continue to display cognitive, educational, and behavioral impairments.
