In 2020, 3.5% of children aged 5–11 years and 10.9% of adolescents aged 12–17 years reported being tired on most days or every day.
Among adolescents aged 12–17, the percentage reporting being tired was higher (12.0%) for those who reported >2 hours of screen time (in addition to that for schoolwork) per weekday than for those who reported ≤2 hours of screen time each day (6.5%). In children aged 5–11 years, the percentage reporting being tired did not differ by hours of screen time (3.6% for >2 hours versus 3.5% for ≤2 hours).
Regardless of the amount of screen time reported, adolescents aged 12–17 years were more likely to report being tired on most days or every day than were children aged 5–11 years.
