Updated June 2018: Nearly 3 in 4 high school students do not meet the daily recommendation for physical activity, according to the most recent Youth Risk Behavior Surveillance System (YRBSS) report. The report also shows that in recent years, high schoolers are spending more recreational time on computers and watching less television. The YRBSS is a biannual measure of self-reported health behaviors among U.S. high school students released by the Centers for Disease Control and Prevention.
The 2017 data reveal that among U.S. high school students, 43% spent three or more hours a day using a computer, playing video games or using social media for fun, up from 41.7% in 2013, and 31.1% in 2011; 20.7% watched television for three or more hours a day, down from 24.7% in 2015, and 32.5% in 2013. The data collection period varies across different measures, but physical activity rates have generally held steady: 26.1% of students were physically active for at least 60 minutes per day and slightly fewer than half, 48.3%, did not attend physical education classes at least once a week in 2017.
