Five or more hours per day of screen time significantly associated with obesity in teens.
The Center for Disease Control's Youth Risk Behavior Surveillance System collects data from grades 9-12 yearly. When looking at the self-reported data on the amount of screen time outside of school work, researchers found 20% were spending 5 plus hours per day of screen time and this was associated with 272% greater odds of sugar-sweetened beverage consumption compared to those who did not watch TV.
PositiveTip: Help your teens limit the amount of screen time to lower their risk of obesity.
Children that go to bed with an electronic device sleep 1 hour less on average.
The National Sleep Foundation's 2014 survey found that almost 72% of children go to bed with an electronic device. The light from these devices disrupts the natural sleep patterns, causing children to sleep 1 hour less on average. Insufficient sleep can adversely affect children's school performance, decision making and overall behavior.
PositiveTip: Parents should set limits and provide healthy alternatives for bedtime electronic use.
The most common kid's activity before bed is watching television.
New Zealand researchers found that children and teens who spend the most time watching TV during the 90 minutes prior to sleep onset got less sleep than those who who engaged in non-screen sedentary activities. Late sleep onset was associated with significantly (P<0.001) more screen-based activity (TV, video games, computers) versus earlier sleep onset. Although casualty can not be inferred from this study, screen time certainly may disrupt or displace sleep.
PositiveTip: Promote longer and better sleep in your children and teens by encouraging limited pre-sleep screen time.
