Implications for practice and research
-
Cardiometabolic biomarkers are associated with higher TV viewing and indicate a reduction in TV viewing for adolescents may be warranted.
-

-
TV viewing may be part of wider cluster of ‘unhealthy’ behaviours.
-
In future, researchers should assess more than TV viewing when looking at sedentary behaviour.
