BMJ urges public health focus on childhood physical activity
BY Matthew Campelli
Public health policy should be focused on preventing the decline of physical activity during childhood, not when individuals reach adolescence, according to British Medical Journal (BMJ) research.
The study revealed that physical activity is in decline for most individuals of both sexes by the age of seven, not when children become teenagers.
The “prevailing view among researchers”, said the report, is that physical activity levels are “adequate” during childhood, but decline dramatically during adolescence, with a marked decrease in activity for girls in particular.
“Much research and policy effort has been directed at adolescent girls, considered to be the ‘high-risk’ group for low physical activity, with the implicit of explicit assumption that children and boys are low risk,” the report states
However, the report found that children aged seven spent half the day sitting. By the age of 15 this had mushroomed to three-quarters of the day.
“Schools should be more active environment,” said report author Professor John Riley. “There should be more activity breaks to break up long periods of sitting.”
The research has been backed by the Youth Sport Trust, which has recently set out its blueprint to make primary schools more active places.
Chris Wright, the charity’s head of wellbeing, said the report “confirms the case for developing schools as active environments.”
“This cannot be about physical activity being another bolt on to what schools’ provide children throughout the day. It has to be integral to everything they do to create a movement culture for their students,” he added.
“Schools have the best opportunity to influence healthy decisions but they are also the place where sitting down for extended periods is becoming the norm.”
