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 level of outcome per 10min (PA/SED) or 1kJ/g (DED) increase in exposure. n included in the analyses varies between 245 and 335, depending on exposure and outcome.
Additionally adjusted for change in accelerometer-registered time.
Model 1: age, sex, baseline value of exposure.
Model 2: model 1+socio-economic status, birth weight, maternal BMI, puberty status at follow-up, sleep duration; model with WC as outcome also includes height.
Model 3: model 2+change in DED for PA/SED exposures and change in MVPA for DED.
Model 4: model 3+objectively measured change in sedentary time (for MPA and VPA exposures) or change in MVPA (for SED exposure).
DED models additionally adjusted for change energy intake (kJ) from drinks and baseline under-reporting.
