  1. IRR incidence rate ratio from Poisson regression analysis; “beta” from linear regression analysis, 95% CI (95% confidence interval), SGA small for gestational age, PTB preterm birth, dis disorder, dep dependence, OCD obsessive compulsive disorder, AS anti-social
  2. *Same adjustments plus for maternal risk behaviours: smoking during gestation, drinking during gestation, inadequate number of prenatal care visits for the gestational age and inadequate weight gain for the gestational age considering the pre-gestational BMI
  3. aAdjusted for socio-demographic variables: maternal schooling, economic class, adolescent childbearing, maternal migration
