Birth-weight centile at term and school performance at 12 years of age: linked cohort study.

Birth-weight centile is associated positively with school performance at 12 years of age across the entire birth-weight spectrum, well beyond the conventional and arbitrary cut-offs for suspected fetal growth restriction. This underlines the importance of developing better tools to diagnose fetal growth restriction and reduced placental function, and to identify those at risk for associated short- and long-term consequences. © 2023 The Authors.
