Active and Sedentary Video Game Time Testing Associations With Adolescents’ BMI

This study used survey methodology to measure opinions of 13to 15-year-olds (N = 176) about sedentary and active video games and the relative amount of time spent with those games, and evaluated correlations between time spent with those two types of games and the body mass index (BMI) of the respondent. Results showed no evidence of any correlation between BMI and relative time devoted to video game usage by type of game (active versus sedentary), nor any support for a correspondence between overall levels of time spent with video games and BMI. Yet, the data did point to a nonlinear association in which those who devoted more than 50% of the total time they spend with video games on sedentary games had a higher BMI than those who spent less than 50% of their video gaming time with sedentary games. Important gender differences also emerged in the adolescents’ opinions of active versus sedentary games.
