The distributions of the scores in contemporary term born children were used as reference. Results are given after multiple imputation as percentages of outcome measures with exact binomial 95% confidence intervals.ResultsAmong 4441 participants, 3083 (69.4%) children were assessed. Rates of severe/moderate neurodevelopmental disabilities were 28% (95% confidence interval 23.4% to 32.2%), 19% (16.8% to 20.7%), and 12% (9.2% to 14.0%) and of mild disabilities were 38.5% (33.7% to 43.4%), 36% (33.4% to 38.1%), and 34% (30.2% to 37.4%) at 24-26, 27-31, and 32-34 weeks, respectively. Assistance at school was used by 27% (22.9% to 31.7%), 14% (12.1% to 15.9%), and 7% (4.4% to 9.0%) of children at 24-26, 27-31, and 32-34 weeks, respectively. About half of the children born at 24-26 weeks (52% (46.4% to 57.3%)) received at least one developmental intervention which decreased to 26% (21.8% to 29.4%) for those born at 32-34 weeks. Behaviour was the concern most commonly reported by parents. Rates of neurodevelopment disabilities increased as gestational age decreased and were higher in families with low socioeconomic status.ConclusionsIn this large cohort of children born preterm, rates of severe/moderate neurodevelopmental disabilities remained high in each gestational age group. Proportions of children receiving school assistance or complex developmental interventions might have a significant impact on educational and health organisations.

Mild neurodevelopmental disabilities, defined as mild cerebral palsy (GMFCS-1), or visual disability ≥3.2/10 and &lt;5/10, or hearing loss &lt;40 dB, or full scale intelligence quotient (minus two to minus one standard deviation) or developmental coordination disorders (Movement Assessment Battery for Children, 2nd edition, total score less than or equal to the fifth centile), or behavioural difficulties (strengths and difficulties questionnaire, total score greater than or equal to the 90th centile), school assistance (mainstream class with support or special school), complex developmental interventions, and parents’ concerns about development. The distributions of the scores in contemporary term born children were used as reference. Results are given after multiple imputation as percentages of outcome measures with exact binomial 95% confidence intervals.ResultsAmong 4441 participants, 3083 (69.4%) children were assessed. Rates of severe/moderate neurodevelopmental disabilities were 28% (95% confidence interval 23.4% to 32.2%), 19% (16.8% to 20.7%), and 12% (9.2% to 14.0%) and of mild disabilities were 38.5% (33.7% to 43.4%), 36% (33.4% to 38.1%), and 34% (30.2% to 37.4%) at 24-26, 27-31, and 32-34 weeks, respectively. Assistance at school was used by 27% (22.9% to 31.7%), 14% (12.1% to 15.9%), and 7% (4.4% to 9.0%) of children at 24-26, 27-31, and 32-34 weeks, respectively. About half of the children born at 24-26 weeks (52% (46.4% to 57.3%)) received at least one developmental intervention which decreased to 26% (21.8% to 29.4%) for those born at 32-34 weeks. Behaviour was the concern most commonly reported by parents. Rates of neurodevelopment disabilities increased as gestational age decreased and were higher in families with low socioeconomic status.ConclusionsIn this large cohort of children born preterm, rates of severe/moderate neurodevelopmental disabilities remained high in each gestational age group. Proportions of children receiving school assistance or complex developmental interventions might have a significant impact on educational and health organisations. Parental concerns about behaviour warrant attention.</abstract><cop>England</cop><pub>BMJ Publishing Group LTD</pub><pmid>33910920</pmid><doi>10.1136/bmj.n741</doi><orcidid>https://orcid.org/0000-0002-1872-4176</orcidid><orcidid>https://orcid.org/0000-0001-7435-5144</orcidid><orcidid>https://orcid.org/0000-0001-9643-0299</orcidid><orcidid>https://orcid.org/0000-0001-9947-270X</orcidid><orcidid>https://orcid.org/0000-0001-7912-9883</orcidid><orcidid>https://orcid.org/0000-0002-4002-802X</orcidid><orcidid>https://orcid.org/0000-0003-4143-1977</orcidid><orcidid>https://orcid.org/0000-0002-8036-8387</orcidid><orcidid>https://orcid.org/0000-0002-2548-2304</orcidid><orcidid>https://orcid.org/0000-0002-2858-148X</orcidid><orcidid>https://orcid.org/0000-0003-3367-512X</orcidid><orcidid>https://orcid.org/0000-0001-9632-7494</orcidid><orcidid>https://orcid.org/0000-0002-4209-934X</orcidid><orcidid>https://orcid.org/0000-0003-4025-4390</orcidid><orcidid>https://orcid.org/0000-0002-1360-7915</orcidid><orcidid>https://orcid.org/0000-0002-1922-734X</orcidid><orcidid>https://orcid.org/0000-0001-6568-0324</orcidid><oa>free_for_read</oa></addata></record>
