Demographic characteristics will be analysed using descriptive statistics. Data will be presented using the mean and standard deviation or median and interquartile range, where appropriate for continuous variables, and frequency and percentage for categorical variables. To assess the effectiveness of the different interventions on objectively measured PA and the other outcomes, the generalized linear model will be used with the outcome measures as dependent variables in separate models, the intervention as an independent variable and controlling for potential confounders (such as gender, body mass index, socioeconomic status, and baseline PA). Statistical significance will be set at p<0.05.
