Screen Use at Bedtime and Sleep Duration and Quality Among Youths.

ABSTRACT:

Importance

Although questionnaire-based cross-sectional research suggests that screen time before bed correlates with poor sleep, self-reported data seem unlikely to capture the complexity of modern screen use, requiring objective night-by-night measures to advance this field.

Objective

To examine whether evening screen time is associated with sleep duration and quality that night in youths.

Design, setting, and participants

This repeated-measures cohort study was performed from March to December 2021 in participant homes in Dunedin, New Zealand. Participants included healthy youths aged 11 to 14.9 years. Data were analyzed from October to November 2023.

Exposure

Objectively measured screen time, captured using wearable or stationary video cameras from 2 hours
