Screen time
hours / day
Hours on a television, console, computer, or phone. Sitting as such and how bright the room is are different clocks.
People report minutes of media that use a screen. Television, consoles, computers, and phones all count. The object is the clock, not the show. Prolonged sitting is chair time. Evening light is spectrum at the eye.
Also called television time, digital media, smartphone use, video games.

In 3,625 Pelotas cohort members, more television and games at 11 and more computer time at 11 and 15 tracked with better Digit Span backward scores at 22 in men, and with nothing in women. In 356 Illinois toddlers, more daily screen minutes tracked with worse parent-rated executive function. Nobody assigned the screens.
