Overall , the current literature supports clearly the dose-response relationship between physical activity and the seven chronic conditions identified .
Moreover , higher levels of physical activity reduce the risk for premature all-cause mortality .
The current Canadian guidelines appear to be appropriate to reduce the risk for the seven chronic conditions identified above and all-cause mortality
This systematic review examines critically the scientific basis for Canada 's Physical Activity Guide for Healthy Active Living for adults .
Particular reference is given to the dose-response relationship between physical activity and premature all-cause mortality and seven chronic diseases ( cardiovascular disease , stroke , hypertension , colon cancer , breast cancer , type 2 diabetes ( diabetes mellitus ) and osteoporosis ) .
The strength of the relationship between physical activity and specific health outcomes is evaluated critically .
The economic costs associated with physical inactivity and obesity in Canada: an update.
The purpose of this analytical review was to estimate the direct and indirect economic costs of  physical inactivity and obesity in Canada in 2001 . The relative risks of diseases associated with physical inactivity and obesity were determined from a meta- analysis of existing prospect i ve studies and applied to the health care costs of these diseases in Canada . Estimates were derived for both the direct health care expenditures and the indirect costs , which included the value of economic output lost because of illness , injury-related work disability , or premature death . The economic burden of physical inactivity was $ 5.3 billion ( $ 1.6 billion in direct costs and $ 3.7 billion in indirect costs ) while the cost associated with obesity was $ 4.3 billion ( $ 1.6 billion of direct costs and $ 2.7 billion of indirect costs ) . The total economic costs of physical inactivity and obesity represented 2.6 % and 2.2 % , respectively , of the total health care costs in Canada . The results underscore the importance of public health efforts aim ed at combating the current epidemics of physical inactivity and obesity in Canada
