Abstract
OBJECTIVE To study the association between prematurity and grade 3 school performance in a contemporary cohort of children. METHODS Population-based retrospective cohort study in Manitoba, Canada. Children born between 1999 and 2011 who had their grade 3 school performance data available were eligible. Preterm birth (<37 weeks) was the exposure of interest assessed using multivariable logistic regression models. Our primary outcomes were 'needs ongoing help' or 'outside the range' in at least two of each of the (1) four numeracy and (2) three reading competencies. RESULTS Of the 186 956 eligible children, 101 436 children (7187 preterm (gestational age, median (IQR) 35 weeks (34, 36)) and 94 249 term (40 weeks (39,40)) were included. Overall, 19% of preterm and 14% of term children had the numeracy outcome (adjusted OR (aOR) 1.38; 95% CI 1.29 to 1.47, p<0.001), while 19% and 13% had the reading outcome (aOR 1.38; 1.29 to 1.48, p<0.001). These differences showed a gestational age gradient. Gestational age (for numeracy, <28 weeks aOR 4.93 (3.45 to 7.03), 28-33 weeks 1.72 (1.50 to 1.98), 34-36 weeks 1.24 (1.15 to 1.34); for reading, <28 weeks 3.51 (2.40 to 5.14), 28-33 weeks 1.72 (1.49 to 1.98), 34-36 weeks 1.24 (1.17-1.37)), male sex, small for gestational age and maternal medical and sociodemographic factors were associated with the numeracy and reading outcomes in this cohort. CONCLUSIONS AND RELEVANCE Children born preterm had poorer performance in grade 3 numeracy and reading proficiencies than children born full term. All children born preterm, not just those born extremely preterm, should be screened for reading and numeracy performance in school and strategies implemented to address any deficits.

Abstract
BACKGROUND Early life exposures can have an impact on a child's developmental trajectory and children born late preterm (34-36 weeks gestational age) are increasingly recognized to have health and developmental setbacks that extend into childhood. OBJECTIVES The purpose of this study was to assess whether late preterm birth was associated with poorer developmental and educational outcomes in the early childhood period, after controlling for health and social factors. METHODS We conducted a retrospective cohort study using administrative databases housed at the Manitoba Centre for Health Policy, including all children born late preterm (34-36 weeks gestational age (GA)) and at full-term (39-41 weeks GA) between 2000 and 2005 in urban Manitoba (N = 28,100). Logistic regression was used to examine the association between gestational age (GA) and outcomes, after adjusting for covariates. RESULTS Adjusted analyses demonstrated that children born late preterm had a higher prevalence of attention deficit hyperactivity disorder (ADHD) (aOR = 1.25, 95% CI [1.03, 1.51]), were more likely to be vulnerable in the language and cognitive (aOR = 1.29, 95% CI [1.06, 1.57]), communication and general knowledge (aOR = 1.24, 95% CI [1.01, 1.53]), and physical health and well-being (aOR = 1.27, 95% CI [1.04, 1.53]) domains of development at kindergarten, and were more likely to repeat kindergarten or grade 1 (aOR = 1.52, 95% CI [1.03, 2.25]) compared to children born at term. They did not differ in receipt of special education funding, in social maturity or emotional development at kindergarten, and in reading and numeracy assessments in the third grade. CONCLUSIONS Given that the late preterm population makes up 75% of the preterm population, their poorer outcomes have implications at the population level. This study underscores the importance of recognizing the developmental vulnerability of this population and adequately accounting for the social differences between children born late preterm and at term.
