The Compendium of Metabolic Equivalents for children was used to categorize physical activity as light (1.6–2.9 metabolic equivalent units [METs]), moderate (3–6 METs), and vigorous activities (> 6.0 METs) . Created summary measures for physical activity behaviors included weekly minutes of activity and weekly moderate-to-vigorous physical activity (MVPA) MET-minutes. Created summary measures for sedentary behaviors included weekly minutes of sitting time and weekly minutes of screen time, defined as sitting time spent using an electronic device such as television viewing, videogames, or texting.
