School performance at nine years of age in very premature and very low birth weight infants: perinatal risk factors and predictors at five years of age. Collaborative Project on Preterm and Small for Gestational Age (POPS) Infants in The Netherlands.

To assess the impact of both perinatal disorders and developmental problems identified at preschool age on school performance, we followed a virtually complete birth cohort of very premature (< 32 completed weeks of gestation) and very low birth weight infants until they were 9 years of age. In 84% of the survivors (n = 813), data on school performance were available for analysis. At the age of 9 years, 19% of the children were in special education.
