The smartphones are believed to be the cause.
“It is worrisome results”, says Associate Professor Anders Raustorp in a press release.
He also points out that previous studies have shown that children who do not deemed to be sufficiently active at that age retains the pattern into adulthood.
The researchers have examined physical activity during school time and leisure, including a pedometer. Between 40 and 100 children in grades two and five in the five schools have been measured on three occasions.
For both girls and boys in grades two, activity was stable, as well as for girls in grade five. By contrast, physical activity significantly, or 24 percent, for boys in grade five. The number of steps was reduced from 16 670 per day to 12 704th
“We can not ignore a smartphone effect”, says Anders Raustorp.
