About three of every four adolescents are in front of the TV and the computer beyond what is recommended, with youths who are overweight in front of screens more than their healthy weight peers, according to a new government report.

For cancer prevention, AICR recommends limiting sedentary activities. Long amounts of time sitting – such as watching TV – links to overweight and obesity, a cause of eight types of cancers. We wrote about the latest research linking inactivity and cancer risk last month.
American teens are eating slightly more fruits and vegetables and fewer sweets, while upping their activity, according to a new study that offers a glimmer of positive findings for improvements among adolescent’s health.
The study, published in Pediatrics, focused on adolescent’s eating and other lifestyle habits. Like adults, there are numerous health reasons for teens to eat well and exercise. What is less well known is the growing body of research suggesting that diet, activity and weight as teenagers – when the body is developing – may play a role in cancer risk decades later.
