BMI, body mass index (kg/m2); MVPA, moderate to vigorous physical activity; SD, standard deviation.
*Higher values indicate better results, except for sitting time and sickness absence; completers, participants who completed all measurements; drop-outs, participants who had missing measurements at T1 and/or T2.
†Highly educated: bachelor or master degree.
‡Sickness absence: percentage of participants who were one or more days absent due to sickness in the previous 12 months (only participants with absence data of at least nine months were included in the analyses; all participants at baseline n = 360; completers n = 142; drop-outs n = 218).
