Bedtime smart device usage and accelerometer-measured sleep outcomes in children and adolescents.

ABSTRACT:

Purpose

We analyzed the association between bedtime smart device usage habits and accelerometer-measured sleep outcomes (total sleeping time, sleep efficiency, and wake after sleep onset) in Hong Kong children and adolescents aged 8-14.

Methods

A total of 467 students in Hong Kong participated in this study from 2016 to 2017. They self-reported their bedtime smart device usage habits. The primary caregiver of each participant was also invited to complete a self-administered questionnaire about the family's social-economic status and bedtime smart device usage habits. An ActiGraph GT3X accelerometer was used to assess participants' 7-day sleep outcomes.

Results

The mean age of the participants was 10.3 (SD 1.9), and 54% were girls. Among the participants, 27% (n = 139)
