*Not all students did accelerometer measurements for assessment of physical activity. In total accelerometers were distributed to 84% of all students (n = 193 and n = 445 in intervention and control schools, respectively). Participation rate is calculated from returned accelerometers with at least one valid day of measurements (≥10 hours) relative to total number of accelerometers distributed. Numbers in brackets show the percentages of all participants with consent.
