High-risk neighbourhoods and behaviour outcomes in children born extremely preterm.

Aim: Study the association between neighbourhood risk and behaviour in extreme preterm (EPT) children. We hypothesised that EPT children living in high-risk neighbourhoods have increased risk of clinical range behaviour problems at age 30-36 months.

Methods: Retrospective analyses of Child Behavior Checklist (CBCL)scores for 739 EPTs born 2005-2016.

High-Risk Neighborhoods and Neurodevelopmental Outcomes in Infants Born Preterm.

Objective: To study the association between neighborhood risk and moderate to severe neurodevelopmental impairment (NDI) at 22-26 months corrected age in children born at <34 weeks of gestation. We hypothesized that infants born preterm living in high-risk neighborhoods would have a greater risk of NDI and cognitive, motor, and language delays.

Study Design: We studied a retrospective cohort of 1291 infants born preterm between 2005 and 2016, excluding infants with congenital anomalies.
