Of studies that have documented the co-development of health-related behaviours, most have only investigated two out of the three guideline behaviours. Kwon et al. (2015) found that most young people experience a decrease in MVPA and an increase in screen time with age, while a subgroup maintained about 50?min of daily MVPA and decreased their screen time [17, 20]. Another co-development study of physical activity and screen time found that children could be clustered in three different patterns: low physical activity/low screen time, increasing physical activity/low screen time, and low physical activity/increasing screen time [21]. To date, only one study has identified co-development trajectories of physical activity, sedentary behaviour, and sleep [22]. Using a sample of youth from two South-Africa cities, Hanson et al., (2019) demonstrated that while physical activity declined over time in both sexes, it was the only variable that was able to distinguish between the different groups of behaviour co-development. In addition, they only found one group in both girls and boys that maintained their physical activity levels over adolescence [22].
