Article Synopsis
- The study aimed to analyze the relationship between smartphone/tablet use and physical activity/sleep in children aged 5 to 10 using a systematic review and meta-analysis approach.
- It included observational studies that met specific criteria and found that increased screen time was linked to decreased sleep duration and quality, with children losing an average of 11 minutes of sleep for every additional hour spent on devices.
- The results showed significant correlations: children using devices were 1.79 times more likely to have shorter sleep duration and 1.53 times more likely to experience poorer sleep quality, while less screen time was associated with higher levels of physical activity.
Increasing physical activity levels during adolescence have been put on the agenda by several researchers. This study verified the association between social support from parents and friends and different amounts of moderate-to-vigorous physical activity (MVPA) among adolescents in public school. The present study had a cross-sectional design and included a representative sample of 1984 adolescents (aged 15-17).
