A major study has found that activity levels drop in children at the age of 7, with experts warning of the impact of ‘digital dependency’ and a sedentary lifestyle.
The Gateshead Millenium Cohort study tracked the activity levels of children over 8 years, from 2006 to 2015, with each child wearing a monitor for a week at a time. The amount of exercise was measured at regular intervals at ages 7, 9, 12 and 15.
The results, published in the British Journal of Sports Medicine, show a fall in exercise levels between the ages of 7 and 15.
Boys spent on average 75 minutes per day exercising at age 7, but only 51 minutes per day by age 15. For girls, this dropped from 63 minutes per day to 41 minutes.

Researchers said much of the decline in activity level was caused by the use of smartphones and computers, as well as by being driven to school rather than walking.
