Science Daily | November 2018 |Children’s sleep not significantly affected by screen time, new study finds
Earlier research has suggested that between 50 and 90 per cent of school- age children might not be getting enough sleep, citing digital technologies as a potential contributor to this. Now research findings from the Oxford Internet Institute at the University of Oxford, indicate that screen time has a modest impact on child’s sleep. The research team used data from the United States’ 2016 National Survey of Children’s Health, which included parents from across the country whom completed self-report surveys on themselves, their children and household. The survey included questions that required caregivers to estimate their child/ren’s sleep duration over one day, if their child/ren went to bed at approximately the same time each night and the amount of time spent on digital screens (including mobile phones, computers, handheld video games and other electronic devices).
Although the study found a correlation, the lead researcher, Professor Andrew Przybylski, author of the study published in the Journal of Pediatrics explains it is modest. “The findings suggest that the relationship between sleep and screen use in children is extremely modest. Every hour of screen time was related to 3 to 8 fewer minutes of sleep a night.” (Via Science Daily)

To determine the extent to which time spent with digital devices predicts meaningful variability in pediatric sleep.
Following a preregistered analysis plan, data from a sample of American children (n = 50 212) derived from the 2016 National Survey of Children’s Health were analyzed. Models adjusted for child-, caregiver-, household-, and community-level covariates to estimate the potential effects of digital screen use.
Each hour devoted to digital screens was associated with 3-8 fewer minutes of nightly sleep and significantly lower levels of sleep consistency. Furthermore, those children who complied with 2010 and 2016 American Academy of Pediatrics guidance on screen time limits reported between 20 and 26 more minutes, respectively, of nightly sleep. However, links between digital screen time and pediatric sleep outcomes were modest, accounting for less than 1.9% of observed variability in sleep outcomes.
Digital screen time, on its own, has little practical effect on pediatric sleep. Contextual factors surrounding screen time exert a more pronounced influence on pediatric sleep compared to screen time itself. These findings provide an empirically robust template for those investigating the digital displacement hypothesis as well as informing policy-making.
