WC, waist circumference; FMI, fat mass index; SED, sedentary physical activity; MPA, moderate physical activity; VPA, vigorous physical activity; DED, dietary energy density; PA, physical activity; MPVA, moderate-to-vigorous physical activity.
β Represents the estimated difference in mean change in outcome per 10min (PA/SED) or 1kJ/g (DED) increase in exposure. n included in the analyses varies between 245 and 336, depending on exposure and outcome.
Additionally adjusted accelerometer-registered time.
Model 1: age, sex.
Model 2: model 1+socio-economic status, birth weight, maternal BMI, puberty status at follow-up, sleep duration; model with WC as outcome also adjusted for height.
Model 3: model 2+baseline DED for PA exposures and baseline MVPA for DED.
Model 4: model 3+objectively measured sedentary time (for MPA and VPA exposures) or MVPA (for SED exposure).
DED models additionally adjusted for energy intake (kJ) from drinks and baseline under-reporting.
