Sleep habits and sleep problems among children born extremely preterm: A Norwegian population-based cohort study

In this project, we investigated the prevalence of sleep problems in children born extremely preterm and identified the conditions during pregnancy, delivery, or the neonatal period associated with these issues. Furthermore, we also examined whether neurological impairments, behavioral problems, and lung disease were risk factors for sleep problems in these children. The data for this project were obtained from the follow-up study “Project Extreme Prematurity”. Prematurity | Westpaed
