However, whether children\u2019s neurodevelopment improves with longer gestations within the full-term range (37\u201341\u2009weeks) is unclear. Given the high rate of obstetric intervention in the USA, it is critical to determine whether long-term outcomes differ for children delivered at each week of term.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This secondary analysis included 39\u00a0199 live-born singleton children of women who were admitted to the hospital in spontaneous labour from the US Collaborative Perinatal Project (1959\u201376). At each week of term gestation, we evaluated development at 8\u2009months using the Bayley Scales of Infant Development, 4\u2009years using the Stanford\u2013Binet IQ (SBIQ) domains and 7\u2009years using the Wechsler Intelligence Scales for Children (WISC) and Wide-Range Achievement Tests (WRAT).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Children\u2019s neurocognitive performance improved with each week of gestation from 37\u2009weeks, peaking at 40 or 41\u2009weeks. Relative to those delivered at 40\u2009weeks, children had lower neurocognitive scores at 37 and 38\u2009weeks for all assessments except SBIQ and WISC Performance IQ. Children delivered at 39\u2009weeks had lower Bayley Mental (\u03b2\u2009=\u2009\u22121.18; confidence interval \u22121.77, \u22120.58) and Psychomotor (\u03b2\u2009=\u2009\u22121.18; confidence interval \u22121.90, \u22120.46) scores. Results were similar for within-family analyses comparing siblings, with the addition of lower WRAT scores at 39\u2009weeks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
