High Step Count, Less Screen Time Lower Obesity Risk in Preteens

The American Academy of Pediatrics updated its guidance for evaluating and treating obesity last month, recommending proactive treatment for children and teens. But although behavioral recommendations for obesity often recommend more physical activity and less screen time, there’s been little research on how combinations of physical activity and screen time can impact children’s weight.

A new national study published in JAMA Network Open has now found that high physical activity does not offset obesity risk among preteens who reported eight or more hours of screen time per day.

Impact of Physical Activity on Screen Time and Obesity Risk In Children

The study also found that low levels of screen time did not offset obesity risk among teens who reported low levels of physical activity.

It is recommended that parents encourage their children to move more through playful activities, sports, and time spent outdoors. Participating in physical activities as a family are important ways to connect and strengthen relationships.

The researchers asked 5,797 preteens 10-14 years old how much time they spent on screens and measured their daily steps using a Fitbit. At the beginning of the pandemic, preteens reported an average of eight hours of recreational screen time daily.

In another recent study published in the Journal of General Internal Medicine, they found that screen time in adolescence was associated with obesity, diabetes, and higher waist circumference 24 years later. That study followed a nationally representative sample of 7,105 adolescents for 24 years.

Parents should have regular conversations with their children about screen use and discourage excessive time spent on screens. They could encourage screen-free time before bedtime or during family meals. Parents can also act as role models for their children with their own screen time and physical activity.
