Life Course and Cohort Patterns in Screen Time Among School-Aged Children in the United States.

ABSTRACT:

Objective

To assess the independent effects of lifecycle (age), historical (period), and generational (cohort) differences that influence the trends in extreme (>3 hours/day) screen time (TV watching plus computer use) among school-aged children in the United States.

Study design

We used data from the National Health and Nutrition Examination Survey and hierarchical age-period-cohort statistical techniques to decompose, describe, and explain the population-level, secular patterns in extreme daily screen viewing time among 5 to 15-year-olds between 1999 and 2018.

Results

We found that 58% of school-aged children engaged in extreme daily screen time. The probability of extreme screen time is greater with each additional year of age, and those children aged 5 to 15 years
