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 .
Awareness, treatment, and control of hypertension in Canada.
The Canadian Heart Health Surveys are cross-sectional , population -based cardiovascular disease risk factor surveys that took place in each of the 10 Canadian provinces between 1986 and 1992 . Hypertension awareness , treatment , and control status are examined . Of 23,129 r and omly selected , noninstitutionalized respondents aged 18 to 74 years , 85 % had four  blood pressure ( BP ) measurements taken under st and ardized conditions  , two at home during a home interview and two at a following clinic visit . The mean of all available measurements was used to determine hypertension status . Estimates are weighted and represent population values . Only 2 % of respondents had never had their BP checked , and 73 % had had their BP checked in the last 12 months . A systolic or diastolic BP > or = 140/90 mm Hg was found in 22 % of participants ( 26 % of men , 18 % of women ) , representing 4.1 million Canadians . Overall , 16 % of participants were treated and controlled ; 23 % were treated and not controlled ; 19 % were not treated and not controlled ; and 42 % were unaware of their hypertension ( 47 % of men and 35 % of women ) . Among hypertensives 18 to 34 years old , 64 % of men and 19 % of women were unaware of their hypertension . Among treated and not controlled hypertensives 63 % had a mean systolic BP > or = 150 mm Hg , and 29 % a diastolic BP > or = 95 mm Hg , suggesting that an important number of Canadians treated for hypertension are still at increased risk . Despite frequent interactions with the health care system , too many Canadians are still not well controlled or are unaware of their hypertension
