  1. Hypothetical interventions on entire cohort as well as on children of parents with low/medium ISCED level and children of mother’s with BMI > 25 kg/m2 at baseline using data from W0 to W3. Model allowing contemporaneous effects of exposures on the outcome
  2. aThe cumulative percent intervened on is the percent of the population required to change behavior in at least one wave
  3. bThe average percent intervened on is the average, across all waves, of the percent of the study population required to change behavior in a given wave
