Obesity, which is partly connected with the time spent using digital media, typically in sedentary mode, has exponentially increased among young people in recent decades. A heavy use of digital media during childhood is associated with a risk of being overweight at a later stage, as shown through a new study by researchers at the Folkhälsan Research Center and the University of Helsinky. Specifically, six hours per week or more of leisure-time physical activity have been found to mitigate the increased risk of being overweight associated with higher amounts of digital media use. The study involved a three-year follow-up analysis of 4,661 Finnish children with a mean age of 11 years at baseline, and then of 14 years in their adolescence at follow-up. The study demonstrated that heavy use of digital media at 11 years of age led to an increased risk of being overweight at the age of 14 years among children who engaged in less than six hours per week of physical activity. This link was not found among children who had said they were physically active for six or more hours per week. The study, entitled “Physical Activity Among Preadolescents Modifies the Long-Term Association Between Sedentary Time Spent Using Digital Media and the Increased Risk of Being Overweight,” was first published online in the Journal of Physical Activity and Health on July 29.
