  1. NB. Adjusted for age, sex, race and level of deprivation in home and school environments. Yearly observations (level 1) were nested within individuals (level 2) which were nested within schools (level 3). CIs Confidence Intervals, BMI SDS standardised body mass index, WC SDS standardised waist circumference, We have used italics to indicate those results where the CIs do not cross a value of 0
