Determinants of three-year change in children’s objectively measured sedentary time
Atkin, Andrew J.; Foley, Louise; Corder, Kirsten; Ekelund, Ulf; van Sluijs, Esther M. F. (Journal article; Peer reviewed, 2016-12-12)Background: Sedentary behaviours (SB) are highly prevalent in young people and may be adversely associated with physical and mental health.
