Association of daily screen time and sleep with concussion history on academic grades: a United States youth risk behavior survey study.

OBJECTIVE

We evaluated the association between daily hours of sleep, daily hours of screen time, concussion history, and academic performance in a sample of adolescents.

STUDY

DESIGN

The United States Youth Risk Behavior Survey datasets from 2017 to 2021 were analyzed. The unweighted sample included 29,388 adolescents, representing an estimated 12,097,952 adolescents. We analyzed history within the last year of sport- or recreation-related concussion, daily television, video games, and computer usage (3+ hours/day on average), sleep (8+ hours of sleep/day), daily physical activity (60+ minutes/day on 5+ days/week), sport participation, and averaging "A" or "B" grades.

RESULTS

The moderation model (R2 = 0.10; p < 0.01) had significant main effects for sport- or recreation-related concussion (adjusted; aOR = 0.16), 3+ hours of screen time (aOR = 0.85), and 8+ hours of sleep (aOR = 1.92) on better academic performance. A significant interaction effect for sport- or recreation-related concussion and 3+ hours of screen time (aOR = 0.57, 95% CI: 0.47, 0.68) and 8+ hours of sleep (aOR = 1.99, 95% CI: 1.60-2.46) were also observed.

CONCLUSION

Adolescents who reported a sport- or recreation-related concussion in the previous year and daily screen time 3+ hours per day or sleep <8 h per day had poorer academic performance than those who reported less screen time and reported more sleep.
