  1. aData were missing for 0.7% (n = 1) families
  2. bThe SES composite score is a weighted score which takes into account the following indicators of SES: gross annual household income (before tax deductions), index of multiple deprivation (IMD), maternal education, home ownership status, household National Statistics Socioeconomic classification (NS-SEC) based on the household representative person, number of bedrooms and number of cars [31]
  3. cCompared to other children of the same age and sex
