Screen stacking among teenage girls
Concurrent screen use and association with lifestyle behaviours and psychosocial health in adolescent females.
Over half the teenage girls used more than one screen at the same time. Overall screen time was linked to lower physical activity, higher BMI and less sleep.
Teenage girls wore an activity monitor for seven days to measure physical activity sleep and sedentary time and reported their screen use. Body mass index (BMI) was measured. Relationships were explored using mixed models accounting for school clustering and confounders.
This study adds to the evidence which shows that excessive screen use during certain times of the day can affect young people's lifestyle behaviours and thus should inform guidelines for screen use in this population.
What next?
Future research is needed in how to best support teenage girls to moderate their screen use, especially at weekend.
