Smartphone Screen Time Characteristics in People With Suicidal Thoughts: Retrospective Observational Data Analysis Study

For Android, the logs capture “screen turned on” and “screen turned off” events; for i OS, the logs capture “locked” and unlocked” events. For i OS, the log also includes an event for each 1% change (positive or negative) in battery charge level. We define a “screen-on bout” for a smartphone as a period of consecutive screen use and a “screen-off bout” as a period of consecutive screen nonuse. Each screen-on bout is followed by a screen-off bout, and vice versa.

Predictors of Parental Barriers to Reduce Excessive Child Screen Time Among Parents of Under-Five Children in Selangor, Malaysia: Cross-sectional Study

Screen time refers to the total amount of time a person spends passively on any screen-based technology such as smartphone, tablet, video game, computer, television, or any wearable device [1,2]. The World Health Organization recommends that children aged younger than 2 years should have no access to screen time whereas for those aged 2 to 5 years, sedentary screen time should not exceed 1 hour per day, and less is better [1].

A Multicomponent Intervention to Reduce Screen Time Among Children Aged 2-5 Years in Chandigarh, North India: Protocol for a Randomized Controlled Trial

The health effects of excessive screen time (ST) include behavioral problems; poor language, cognitive development, skills, memory, and executive function; lower social competence; sleep disturbances; depression; and low self-esteem [10-17]. In light of this, the present randomized controlled trial was planned with an assumption that ST might be causally associated with emotional behaviors, sleep behaviors, and children’s level of physical activity.
