Kids should move more to prevent heart disease risk, say experts.
However, when evaluating the risk of cardiovascular disease, screen time appears to be worse than overall sedentary time.
As members of TEAM PRODIGY, an inter-university research team that includes researchers from the University of Ottawa
"Although results in this study suggest that in children, time spent in moderate-to-vigorous physical activity appears more important than time spent in sedentary activities, with regard to cardiometabolic health, both increasing children's participation in physical activity and reducing their screen-related sedentary time are important public health targets to achieve," said first author, Dr. Jean-Philippe Chaput, who is a researcher at the CHEO Research Institute and a cross-appointed professor at the University of Ottawa.
This cross-sectional study involved over 500 participants between the ages of 8 and 10. The measured outcomes included waist circumference, systolic Systolic
The phase of blood circulation in which the heart's pumping chambers (ventricles) are actively pumping blood. The ventricles are squeezing (contracting) forcefully, and the pressure against the walls of the arteries is at its highest. and diastolic blood pressure Diastolic blood pressure
Blood pressure when the heart is resting between beats.

Higher levels of MVPA were associated with lower waist circumference, fasting triglycerides and diastolic blood pressure, and higher HDL cholesterol, irrespective of sedentary time.
In contrast, sedentary time was positively associated with diastolic blood pressure, but after adjustment for MVPA, the association was no longer statistically significant.
Self-reported screen time was positively associated with waist circumference and negatively associated with HDL cholesterol independent of MVPA.
