The new study estimated for the first time how trends changed between 2001-2016 – applying the trends from 73 countries who did repeat surveys during that period to all 146 countries.
Globally, the prevalence of insufficient physical activity slightly decreased in boys between 2001 and 2016 (from 80% to 78%), but there was no change over time in girls (remaining around 85%).
The countries showing the greatest decreases in boys being insufficiently active were Bangladesh (from 73% to 63%), Singapore (78% to 70%), Thailand (78% to 70%), Benin (79% to 71%), Ireland (71% to 64%), and the USA (71% to 64%).
However, among girls, changes were small, ranging from a 2 percentage-point decrease in Singapore (85% to 83%) to a 1 percentage-point increase in Afghanistan (87% to 88%).
The authors note that if these trends continue, the global target of a 15% relative reduction in insufficient physical activity – which would lead to a global prevalence of less than 70% by 2030 – will not be achieved.
