Adherence to Combined Healthy Movement Behavior Guidelines among Adolescents: Effects on Cardiometabolic Health Markers.

Background: The combined movement behavior guidelines for adolescents recommend ≥60 min of moderate to vigorous physical activity, ≤2 h of screen time, and 8-10 h of sleep.

In addition, another objective of the study was to examine the effects of compliance with these guidelines on cardiometabolic health markers.
