 This study found that many Canadian children and youth are not meeting recommended movement behaviours during the Covid-19 outbreak. The results suggest that the virus has caused a decrease in physical activity, increased sedentary behaviour and decreased sleep duration among this population. Additionally, some parents have adopted new hobbies or accessed new resources to compensate for the lack of outdoor activities. Parents who encourage their children to be physically active and provide support and encouragement for participation in physical activities are more likely to see positive outcomes in their children's movement behaviours.
