Daily Screen Time Among Teenagers: United States, July 2021–December 2023

The percentage of teenagers with 4 hours or more of daily screen time varied by parental education and urbanization level.

• The percentage of teenagers ages 12–17 living in families with incomes of less than 200% of the federal poverty level with 4 hours or more of daily screen time (51.7%) was comparable to the percentage of teenagers living in families with incomes of 200% of the federal poverty level or more (49.6%) (Figure 3, Table 3).
• Teenagers living in families where the highest parental education was some college or less were more likely to have 4 hours or more of daily screen time (55.0%) compared with teenagers living in families where the highest parental education was a college degree or higher (45.2%).
• Teenagers living in metropolitan areas were more likely to have 4 hours or more of daily screen time (51.4%) compared with teenagers living in nonmetropolitan areas (43.3%).

The percentage of teenagers who had symptoms of anxiety or depression in the past 2 weeks was higher among those with 4 hours or more of daily screen time.

• During July 2021 through December 2023, about 1 in 4 teenagers ages 12–17 with 4 hours or more of daily screen time had experienced anxiety (27.1%) or depression (25.9%) symptoms in the past 2 weeks (Figure 4, Table 4).
• Teenagers who had 4 or more hours of daily screen time were more likely to have had anxiety symptoms in the past 2 weeks (27.1%) compared with teenagers with less than4 hours of daily screen time (12.3%).
• Teenagers who had 4 or more hours of daily screen time were more likely to have had depression symptoms in the past 2 weeks (25.9%) compared with teenagers with less than4 hours of daily screen time (9.5%).

Summary

During July 2021 through December 2023, 50.4% of teenagers self-reported 4 hours or more of daily screen time. Teenagers who were Black, older (ages 15–17), living in metropolitan areas, or living in families with lower parental education were most likely to have 4 hours or more of daily screen time. Teenagers with higher daily screen time were more likely to experience both anxiety and depression symptoms over the past 2 weeks, which is consistent with previous research (3,4).

As technology and screens continue to develop, their influence on the lives of children changes, making it increasingly important to expand our understanding of the patterns of screen time use overall and among selected subgroups (5).

Definitions

Anxiety symptoms: Measured using the Generalized Anxiety Disorder–2 (GAD–2) scale (6). Teenagers were asked, “Over the last 2 weeks, how often have you been bothered by feeling nervous, anxious, or on edge?” and “Over the last 2 weeks, how often have you been bothered by not being able to stop or control worrying?” Response options were “not at all,” “several days,” “more than half the days,” and “nearly every day,” with scores assigned as zero, one, two, or three, respectively. Teenagers who scored three or more on the two questions combined were considered to have symptoms of anxiety per GAD–2 scoring guidelines. Teenagers who did not answer both questions were excluded.

Depression symptoms: Measured using the Patient Health Questionnaire–2 (PHQ–2) (7). Teenagers were asked, “Over the last 2 weeks, how often have you been bothered by having little interest or pleasure in doing things?” and “Over the last 2 weeks, how often have you been bothered by feeling down, depressed or hopeless?” Like the GAD–2, response options were “not at all,” “several days,” “more than half the days,” and “nearly every day,” with scores assigned as zero, one, two, or three, respectively. Teenagers who scored three or more on the two questions combined were considered to have symptoms of depression per PHQ–2 scoring guidelines. Teenagers who did not answer both questions were excluded.

Family income as a percentage of the federal poverty level: Based on the federal poverty level, which was calculated from the family’s income in the previous calendar year and family size using the U.S. Census Bureau’s poverty thresholds (8). Family income was imputed when missing (9).

Parental education: Reflects the highest education level completed by the teenager’s parent or parents who lived in the household, regardless of the parent’s age. Information on parents not living in the household was not obtained. If both parents lived in the household but information on one parent’s education was unknown, the other parent’s education was used. If both parents lived in the household and education was coded as missing for both, or no parents lived in the household, parental education was unknown.

Race and Hispanic origin: Teenagers categorized as non-Hispanic indicated one race only; respondents had the option to select more than one racial group. Hispanic teenagers could be of any race or combination of races. Estimates for non-Hispanic children of races other than Asian, Black, and White are not shown due to the inability to make statistically reliable estimates for these groups, but they are included in total estimates.

Screen time: Based on the response to the question, “On most weekdays, how many hours do you spend a day in front of a TV, computer, cellphone or other electronic device watching programs, playing games, accessing the internet, or using social media?” Respondents were instructed not to include time spent for schoolwork. Response options were “Less than 1 hour; 1 hour; 2 hours; 3 hours; 4 or more hours.”

Urbanization level: Metropolitan size and status were determined using the 2013 National Center for Health Statistics urban–rural classification scheme for counties (10), by merging the geographic federal information processing standard codes for the county of household residence with the county-level federal information processing standard codes from the classification scheme’s data set. Metropolitan includes large central, large fringe, medium, and small metropolitan counties. Nonmetropolitan includes micropolitan and noncore counties.

Data source and methods

NHIS–Teen is a web-based, self-administered follow-back survey of adolescents sampled in NHIS as part of the Sample Child interview. It includes adolescents ages 12–17 whose parent completed the NHIS Sample Child interview and provided permission for their teenager to be invited to participate in NHIS–Teen. Eligible teenagers received an invitation letter and a series of planned reminders with instructions for completing a 15-minute online health survey. On average, teenagers completed the survey within 2 to 3 weeks of the parent interview.

NHIS–Teen covers topics such as physical activity, sedentary activity, use of social media and electronic devices, friendships, bullying, symptoms of poor mental health, and resilience as reported by teenagers themselves. The parent permission rate for NHIS–Teen was 60.4%, and the teen participation rate was 46.2%, resulting in an overall NHIS–Teen interview rate of 27.9%. More detailed information about NHIS–Teen, including its methodology and recruitment strategy, has been previously published (11).

Teen and family characteristics are based on data provided by the teenager’s parent as part of the NHIS Sample Child interview. Point estimates and the corresponding confidence intervals were calculated using SAS-callable SUDAAN software (12) to account for the complex sample design of NHIS–Teen. All estimates in this report meet National Center for Health Statistics data presentation standards for proportions (13). Differences between percentages were evaluated using two-sided significance tests at the 0.05 level.
