Teen Physical Activity Influenced by Friends, New Study from Youth-Nex - Kinesiology


John Sirard, Assistant Professor with Youth-Nex and Kinesiology, published a new study in the American Journal of Preventive Medicine showing that teens influence each other when it comes to their physical activity levels. The results also showed different behaviors for girls and boys.

“Overall, boys engage in more moderate to vigorous physical activity and screen time than girls. Both the physical activity and screen time of boys was found to be more influenced by the behaviors of their female friends than their male friends. For girls, physical activity was associated with that of both their male and female friends’. However, females’ screen time was associated with their male friends’ screen time but not with their female friends’ screen time.” —
