The aim of the study was to follow-up a population-based cohort of Extremely Low Birth Weight (ELBW), extremely low gestational age children at 5 years. No follow-up studies had been carried out in Estonia about development of preterm born children beyond 3 years of age so this study provides a valuable insight into outcomes in older children born preterm. Participants were born in Estonia in 2002-2003 at a birth weight of less than 1000g and before 29 weeks gestational age.
