Association of Birth Weight Centiles and Gestational Age With Cognitive Performance at Age 5 Years.

ABSTRACT:

Importance

Birth weight percentiles (BWPs) are often dichotomized at the 10th percentile and show statistically significant association with later cognitive performance, for both preterm and term-born children. However, research testing nonlinear associations between BWPs and cognitive performance is scarce.

Objective

To investigate culturally invariant, nonlinear associations of BWPs and gestational age with later cognitive performance.

Design, setting, and participants

In this cohort study, participants with valid neonatal and cognitive data were combined from 4 observational cohorts, including the Millennium Cohort Study, the National Longitudinal Survey of Youth 1979 Child and Young Adult cohort, Growing Up in Ireland, and the Longitudinal Study of Australian Chil
