Stability of television viewing and electronic game/computer use in a prospective cohort study of Australian children: relationship with body mass index Academic Article uri icon


  • BACKGROUND: While much cross-sectional data is available, there have been few longitudinal investigations of patterns of electronic media use in children. Further, the possibility of a bi-directional relationship between electronic media use and body mass index in children has not been considered.

Children were classified as meeting electronic media use guidelines if their total screen time was
