Associations of gestational age with CSHQ score and sleep disorder. Legend: Associations of gestational age with CSHQ scores and sleep disorder. A Compared with full-term birth, preschool children born very-preterm, moderate-preterm, late-preterm, early-term and post-term were associated with higher CSHQ scores, all p < 0.001. B A fit spline described a U-shape relationship of gestational age (weeks) with CSHQ scores. C Compared with full-term birth, preschool children born very-preterm, moderate-preterm, late-preterm and post-term were associated with a higher prevalence of pediatric sleep disorder, all p < 0.001
