Screen time before bed linked with less sleep and a higher BMI in kids

It may be tempting to let your kids stay up late playing games on their smartphones, but using digital devices before bed may contribute to sleep and nutrition problems in children, according to researchers.



After surveying parents about their kids' technology and sleep habits, researchers found that using technology before bed was associated with less sleep, poorer sleep quality, more fatigue in the morning and, in the children that watched TV or used their cell phones before bed, higher body mass indexes (BMI).


Researchers saw technology before bed being associated with less sleep and higher BMIs. They also saw this technology use being associated with more fatigue in the morning, which circling back, is another risk factor for higher BMIs. So its a loop pattern forming.


Previous research has found associations between more technology use and less sleep, more inattention, and higher BMIs in adolescents. But even though research shows that 40 percent of children have cell phones by fifth grade, the researchers said not as much was known about the effects of technology on a younger population.


Fuller said that because sleep is so critical to a child's development, she was interested in learning more about the connection between screen time right before bed and how well those children slept, as well as how it affected other aspects of their health.


The researchers asked the parents of 234 children between the ages of 8 and 17 years about their kids' sleep and technology habits. The parents provided information about their children's' technology habits, sleep patterns, nutrition and activity. The researchers also asked the parents to further specify whether their children were using cell phones, computers, video games or television during their technology time.


After analyzing the data, the researchers found several adverse effects associated with using different technologies right before bed.

Children who reported watching TV or playing video games before bed got an average of 30 minutes less sleep than those who did not, while kids who used their phone or a computer before bed averaged an hour less of sleep than those who did not.


There was also an association between using all four types of technology before bed and increased cell phone use at night, such as waking up to text someone, with watching TV resulting in the highest odds.
