We followed the methods outlined in Bakrania et al. [11] to classify participants in this study into 4 mutually exclusive behavioural categories according to their levels of physical activity and sedentary behaviour. Based on Bakrania et al. [11], and other studies [12, 29], the light physical activity-to-sedentary time ratio was used to classify participants in this study as low sedentary if they resided in the first quartile.
