Physical Activity Levels-Physical Inactivity-Ecological Study-Global Impact

Lack of exercise as 'deadly' as smoking

ConclusionThis ecological study estimated the global impact of physical inactivity and models the theoretical lives saved if physical inactivity levels were to be reduced across the globe.This study serves to highlight the large and wide-ranging impact of physical inactivity on global disease levels and death. However the following study limitations should be considered: Physical activity was based on self-reported physical activity levels, which can be misleading. The authors of the research say that this tends to underestimate differences between active and inactive people and so would underestimate the impact of physical inactivity globally. The researchers therefore concluded that their estimates ‘are likely to be very conservative’. Using a more objective measure of physical ... read more..
