Active Screen Time Among U.S. Youth Aged 9-18 Years, 2009

This study documented the prevalence of active screen time (i.e., screen time that includes active games, exercise or dance videos, or TV exercise programs) and identified characteristics associated with it among youth 9-18 years of age.

This cross-sectional study was conducted on a convenience sample of 1,165 youth using the 2009 Styles Surveys; data were weighted to approximate the Current Population Survey. We calculated descriptive statistics and conducted multivariable logistic regression to identify characteristics associated with active screen time by estimating adjusted odds ratio (aOR) and 95 percent confidence intervals (CIs).

The sample comprised 51.4 percent boys, and almost 60 percent were non-Hispanic white. The prevalence of active screen time ≥1 hour/day was 31.2 percent on a typical school day and 41.6 percent on a typical weekend day. Logistic regression revealed youth with physical activity of 3-5 days/week had higher odds of active screen time ≥1 hour/day compared with youth with no physical activity (aOR school day=2.8, 95 percent CI 1.5-5.2; aOR weekend day=2.3, 95 percent CI 1.4-3.9). Certain characteristics (i.e., sex, age group, race/ethnicity, income, and sedentary screen time) were significantly associated with active screen time ≥1 hour/day, but associations were inconsistent for school and weekend days.

Three in 10 youth are engaging in at least 1 hour of active screen time on school days, and about 4 in 10 youth are engaging in at least one hour on weekend days. Understanding the use of active screen time and associated characteristics are important for developing interventions addressing screen time and physical activity.
