Perinatal predictors were reported by the mother prospectively in pregnancy and the Strengths and Difficulties Questionnaire (SDQ) was completed by the mother at 7-years-old. This was dichotomised at recommended clinical cut-off (total&gt;16) Building on our previous model in a French cohort, 15 perinatal parameters spanning maternal pre-pregnancy health, biological and psychosocial pregnancy-specific-experiences, maternal health behaviours in pregnancy and sociodemographic factors were entered into a logistic regression using the least absolute selection and shrinkage operator.

Children who died perinatally, those with unclear or very low (&lt;32 weeks) gestational age, as well as those with severe congenital syndromes or severe or unclear cognitive impairments were excluded. The main outcome was the cumulative incidence of ADHD, defined by ICD-10 codes F90, F90.0, F90.1, F90.8, F90.9, or F98.8. This outcome was adjusted for gestational age, sex, birth cohort, and maternal psychosocial factors during the child's first 3 years.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The cumulative incidence of ADHD diagnosis at 0–12 years was 4.0% (3.9−4.0%) for the entire study (<i>N</i> = 324,766), 6.4% (6.2−6.5%) for boys, and 1.5% (1.5−1.6%) for girls. An ADHD diagnosis was more likely (adjusted odds ratios [95% confidence intervals]) among boys (4.6 [4.3–4.8]) and moderately preterm children (1.3 [1.2–1.4]), as well as in cases where the mother smoked during pregnancy (2.0 [1.9–2.1]), had a psychiatric disorder (2.0 [1.9–2.1]), or lived alone (1.4 [1.3–1.5]), compared to opposite condition. The cumulative incidence of ADHD diagnoses increased over time in both primary and secondary healthcare settings.
