It is unclear whether children born late preterm (34\u201336 weeks) compared to full term (\u2265\u200939 weeks), have different growth trajectories. Our objective was to evaluate the association between gestational age groups and growth trajectories of children born between 2006\u20132014 and followed to 2021 in Ontario, Canada.<\/p>\n<p><strong>Methods<\/strong> \u2014 We conducted a retrospective cohort study of children from singleton births in TARGet Kids! primary care network with repeated measures of weight and height\/length from birth to 14 years, who were linked to health administrative databases. Piecewise linear mixed models were used to model weight (kg\/month) and height (cm\/month) trajectories with knots at 3, 12, and 84 months. Analyses were conducted based on chronological age.<\/p>\n<p><strong>Results<\/strong> \u2014 There were 4423 children included with a mean of 11 weight and height measures per child. The mean age at the last visit was 5.9 years (Standard Deviation: 3.1). Generally, the more preterm, the lower the mean value of weight and height until early adolescence. Differences in mean weight and height for very\/moderate preterm and late preterm compared to full term were evident until 12 months of age. Weight trajectories were similar between children born late preterm and full term with small differences from 84\u2013168 months (mean difference (MD) -0.04 kg\/month, 95% CI -0.06, -0.03). Children born late preterm had faster height gain from 0\u20133 months (MD 0.70 cm\/month, 95% CI 0.42, 0.97) and 3\u201312 months (MD 0.17 cm\/month, 95% CI 0.11, 0.22).<\/p>\n<p><strong>Conclusions<\/strong> \u2014 Compared to full term, children born late preterm had lower average weight and height from birth to 14 years, had a slightly slower rate of weight gain after 84 months and a faster rate of height gain from 0\u201312 months. Follow-up is needed to determine if growth differences are associated with long-term disease risk.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Background \u2014 Evidence suggests that accelerated postnatal growth in children is detrimental for adult cardiovascular health.
