Associations between grades and physical activity and food choices

Purpose – The purpose of this paper is to explore the relationship between television viewing time, physical activity level, food consumption patterns, and academic performance of adolescents in a large urban school district in the USA where health disparities are prevalent, particularly among minority residents. Design/methodology/approach – The 2010 Youth Risk Behavior Survey was used to analyze the relationship between academic grades and physical activity patterns and food consumption in a large urban school district serving over 77,000 students. Findings – Results indicated that students who self-reported grades of As and Bs had higher levels of physical activity and less screen time compared to students who reported grades of Ds and Fs. Further, as grades decreased the consumption of soda and fast food increased. Originality/value – Higher grades track significantly with improved physical activity and lower intake of soda and fast food. These findings provide additional support for the role of regular physical activity and its positive effect on academic performance.
