Abstract

Background: Larger brain volumes in the neonatal period are associated with better 2-year cognitive development in children born moderate-to-late preterm (MLP). Whether these associations persist into school age for executive function (EF) is unknown. Methods: Children born MLP underwent brain magnetic resonance imaging (MRI) at term-equivalent age (n = 168) and EF assessment at 9 years (n = 159). Mean or median differences in EF subdomains (attentional control, cognitive flexibility, goal setting, behavioral EF) for a unit increase in brain volumes were estimated using linear regression, overall and for subgroups defined by gestational age at MRI, sex and excluding participants with developmental delay at 2 years. Results: There were few associations between brain volumes and EF. Small effects were found for larger total tissue (mean difference = 0.16; 95% CI = −0.04, 0.36; p = 0.11), white matter (mean difference = 0.21; 95% CI = 0.05, 0.38; p = 0.01) and subcortical gray matter (mean difference = 0.17; 95% CI = −0.01, 0.34; p = 0.06) volumes and improved goal setting. Subgroup relationships were similar. Conclusion: Neonatal brain volumes in MLP children are not strongly associated with school-age EF. Imaging techniques with higher sensitivity, and other risk factors for poorer EF should be explored.
