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 .
Risk Factors of Stroke Incidence and Mortality: A 12‐Year Follow‐up of the Oslo Study
Background and Purpose The objective of this study was to determine the risk factors of stroke incidence and mortality . Methods Our data are based on a prospect i ve cohort study of men aged 40 to 49 years after 12 years of follow-up . Results In age-adjusted Cox proportional-hazards regression analysis of 14 403 healthy men , diastolic blood pressure was a stronger predictor for stroke incidence and mortality than systolic blood pressure . Smoking was a stronger predictor of mortality than of incidence . However , there was no dose-response relation among smokers by increased cigarette consumption . Total serum cholesterol was a significant ( P < .05 ) risk factor for stroke mortality and of borderline significance ( P=.08 ) for stroke incidence . Increased physical activity  at leisure was associated with reduced stroke incidence but not mortality . The myocardial infa rct ion risk score comprising systolic blood pressure , total serum cholesterol , and daily cigarette smoking was a strong predictor of mortality and incidence . Body mass index , triglycerides , blood glucose , and physical activity at work were not found to be risk factors for stroke . Conclusions Reduction of blood pressure , cessation of smoking , lowered cholesterol  , and increased physical activity at leisure  are individual measures to reduce the risk of stroke
