In a large, community-based cardiovascular disease prevention study in Eastern Finland, independent random population samples were surveyed in 1972, 1977 and 1982. The leisure-time physical activity (LTPA), occupational physical activity (OPA), and socioeconomic and lifestyle characteristics were assessed. In men and women aged 30-59, the proportion with high LTPA increased from 1972 to 1982 by approximately one half (p less than 0.001), whereas that of high OPA decreased during the same period (p less than 0.001). In both sexes, high overall physical activity fell from 1972 to 1977 (p less than 0.001), but no more from 1977 to 1982. The proportion of entirely sedentary remained stable. Education, income and younger age showed a positive, body mass index, smoking and OPA a graded, negative association with high LTPA in 1972 and 1982. Significant (p less than 0.001) differences in 10-year trends of changes in LTPA were observed: men and women with low education or income increased LTPA more than those with high education and income. Socioeconomic factors, such as income and education, appear to have lost importance as determinants of population-wide exercise, whereas the clustering of low physical activity with overweight and smoking has increased.
To provide updated, evidence-based recommendations for the therapy of hypertension in adults.
For patients with hypertension, a number of antihypertensive agents may control blood pressure. Randomized trials evaluating first-line therapy with thiazides, beta-adrenergic antagonists, angiotensin-converting enzyme inhibitors, calcium channel blockers, alpha-blockers, centrally acting agents or angiotensin II receptor antagonists were reviewed.
The health outcomes that were considered were changes in blood pressure, cardiovascular morbidity, and cardiovascular and/or all-cause mortality rates. Economic outcomes were not considered due to insufficient evidence.
MEDLINE was searched for the period March 1999 to October 2001 to identify studies not included in the 2000 revision of the Canadian Recommendations for the Management of Hypertension. Reference lists were scanned, experts were polled, and the personal files of the subgroup members and authors were used to identify other published studies. All relevant articles were reviewed and appraised, using prespecified levels of evidence, by content experts and methodological experts.
A high value was placed on the avoidance of cardiovascular morbidity and mortality.
Various antihypertensive agents reduce the blood pressure of patients with sustained hypertension. In certain settings, and for specific classes of drugs, blood-pressure lowering has been associated with reduced cardiovascular morbidity and/or mortality.
The present document contains detailed recommendations pertaining to treatment thresholds, target blood pressures, and choice of agents in various settings in patients with hypertension. The main changes from the 2000 Recommendations are the addition of a section on the treatment of hypertension in patients with diabetes mellitus, the amalgamation of the previous sections on treatment of hypertension in the young and old into one section, increased emphasis on the role of combination therapies over repeated trials of single agents and expansion of the section on the treatment of hypertension after stroke. Implicit in the recommendations for therapy is the principle that treatment for an individual patient should take into consideration global cardiovascular risk, the presence and/or absence of target organ damage, and comorbidities.
All recommendations were graded according to strength of the evidence and voted on by the Canadian Hypertension Recommendations Working Group. Individuals with potential conflicts of interest relative to any specific recommendation were excluded from voting on that recommendation. Only those recommendations achieving high levels of consensus are reported here. These guidelines will continue to be updated annually.
The 2004 Canadian Hypertension Education Program recommendations for the management of hypertension: Part I--Blood pressure measurement, diagnosis and assessment of risk.
To provide updated, evidence-based recommendations for the assessment of the diagnosis, cardiovascular risk and identifiable causes for adults with high blood pressure.
For persons in whom a high blood pressure value is recorded, the assignment of a diagnosis of hypertension is dependent on the appropriate measurement of blood pressure, the level of the blood pressure elevation and the duration of follow-up. In addition, the presence of concomitant vascular risk factors, target organ damage and established atherosclerotic diseases should be assessed to determine the urgency, intensity and type of treatment. For persons diagnosed as having hypertension, defining overall risk of adverse cardiovascular outcomes requires an assessment of concomitant vascular risk factors, including laboratory testing, a search for target organ damage and an assessment for modifiable causes of hypertension. Home and ambulatory blood pressure assessment and echocardiography are options for selected patients.
The identification of persons at increased risk of adverse cardiovascular outcomes; the quantification of overall cardiovascular risk; and the identification of persons with potentially modifiable causes of hypertension.
Medline searches were conducted from November 2001, one year before the period of the last revision of the Canadian recommendations for the management of hypertension, to October 2003. Reference lists were scanned, experts were polled, and the personal files of subgroup members and authors were used to identify other studies. Identified articles were reviewed and appraised using prespecified levels of evidence by content experts and methodological experts.
A high value was placed on the identification of persons at increased risk of cardiovascular morbidity and mortality, and persons with identifiable and potentially modifiable causes of hypertension.
The identification of persons at higher risk of cardiovascular disease will permit counselling for lifestyle maneuvers and introduction of antihypertensive drugs to reduce blood pressure for patients with sustained hypertension. The identification of specific causes of hypertension may permit the use of cause-specific interventions. For certain subgroups of patients and specific classes of drugs, blood pressure lowering has been associated with reduced cardiovascular morbidity and/or mortality.
The document contains recommendations for blood pressure measurement, diagnosis of hypertension and assessment of cardiovascular risk for adults with high blood pressure. These include the accurate measurement of blood pressure, criteria for diagnosis of hypertension, and recommendations for follow-up, assessment of overall cardiovascular risk, routine and optional laboratory testing, assessment for renovascular and endocrine causes, home and ambulatory blood pressure monitoring, and the role of echocardiography for those with hypertension.
All recommendations were graded according to strength of evidence and voted on by the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. Only the recommendations that achieved high levels of consensus are reported. These guidelines will be updated annually.
To provide updated, evidence-based recommendations for the management of hypertension in adults.
For patients who require pharmacological therapy for hypertension, a number of antihypertensive agents may be used. Randomized trials evaluating first-line therapy with diuretics, beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, calcium channel blockers (CCBs), alpha-blockers, centrally acting agents or angiotensin receptor antagonists were reviewed. Also, randomized trials evaluating other agents, such as statins or acetylsalicylic acid, in patients with hypertension were reviewed. Changes in cardiovascular morbidity and mortality were the primary outcomes of interest. In addition, other relevant outcomes such as development of end-stage renal disease or changes in blood pressure were examined where appropriate.
MEDLINE searches were conducted from November 2001 to October 2003 to update the 2001 Recommendations for the management of hypertension. Reference lists were scanned, experts were contacted, and the personal files of the subgroup members and authors were used to identify additional published studies. All relevant articles were reviewed and appraised independently, using prespecified levels of evidence by content and methodology experts.
This document contains detailed recommendations and supporting evidence on treatment thresholds, target blood pressures and choice of agents for hypertensive patients with or without comorbidities. Lifestyle modifications are a key component of any antiatherosclerotic management strategy and detailed recommendations are contained in a separate document. Key recommendations for pharmacotherapy include the following: treatment thresholds and targets should take into account each individual's global atherosclerotic risk, target organ damage and comorbidities, with particular attention to systolic blood pressure; blood pressure should be lowered to 140/90 mmHg or less in all patients, and 130/80 mmHg or less in those with diabetes mellitus or renal disease (125/75 mmHg or less in those with nondiabetic renal disease and more than 1 g of proteinuria per day); most adults with hypertension require more than one agent to achieve target blood pressures; for adults without compelling indications for other agents, initial therapy should include thiazide diuretics; other agents appropriate for first-line therapy for diastolic hypertension with or without systolic hypertension include beta-blockers (in those younger than 60 years), ACE inhibitors (in non-Blacks), long-acting dihydropyridine CCBs or angiotensin receptor antagonists; other agents appropriate for first-line therapy for isolated systolic hypertension include long-acting dihydropyridine CCBs or angiotensin receptor antagonists; certain comorbidities provide compelling indications for first-line use of other agents: in patients with angina, recent myocardial infarction or heart failure, beta-blockers and ACE inhibitors are recommended as first-line therapy; in patients with diabetes mellitus, ACE inhibitors or angiotensin receptor antagonists (or thiazides in patients with diabetes mellitus without albuminuria) are appropriate first-line therapies; and in patients with mild to moderate nondiabetic renal disease, ACE inhibitors are recommended; all hypertensive patients should have their fasting lipids screened and those with dyslipidemia should be treated using the thresholds, targets and agents as per the Recommendations for the management of dyslipidemia and the prevention of cardiovascular disease; and selected patients with hypertension should also receive statin and/or acetylsalicylic acid therapy.
All recommendations were graded according to the strength of the evidence and voted on by the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. Individuals with irreconcilable competing interests (declared by all members, compiled and circulated before the meeting) relative to any specific recommendation were excluded from voting on that recommendation. Only recommendations achieving at least 70% consensus are reported here. These guidelines will continue to be updated annually.

To update the evidence-based recommendations for the prevention and treatment of hypertension in adults for 2010.
For lifestyle and pharmacological interventions, randomized trials and systematic reviews of trials were preferentially reviewed. Changes in cardiovascular morbidity and mortality were the primary outcomes of interest. However, for lifestyle interventions, blood pressure lowering was accepted as a primary outcome given the general lack of long-term morbidity and mortality data in this field. Progressive renal impairment was also accepted as a clinically relevant primary outcome among patients with chronic kidney disease.
A Cochrane Collaboration librarian conducted an independent MEDLINE search from 2008 to August 2009 to update the 2009 recommendations. To identify additional studies, reference lists were reviewed and experts were contacted. All relevant articles were reviewed and appraised independently by both content and methodological experts using prespecified levels of evidence.
For lifestyle modifications to prevent and treat hypertension, restrict dietary sodium to 1500 mg (65 mmol) per day in adults 50 years of age or younger, to 1300 mg (57 mmol) per day in adults 51 to 70 years of age, and to 1200 mg (52 mmol) per day in adults older than 70 years of age; perform 30 min to 60 min of moderate aerobic exercise four to seven days per week; maintain a healthy body weight (body mass index 18.5 kg/m(2) to 24.9 kg/m(2)) and waist circumference (less than 102 cm for men and less than 88 cm for women); limit alcohol consumption to no more than 14 standard drinks per week for men or nine standard drinks per week for women; follow a diet that emphasizes fruits, vegetables and low-fat dairy products, dietary and soluble fibre, whole grains and protein from plant sources, and that is low in saturated fat and cholesterol; and consider stress management in selected individuals with hypertension. For the pharmacological management of hypertension, treatment thresholds and targets should be predicated on the patient's global atherosclerotic risk, target organ damage and comorbid conditions. Blood pressure should be decreased to less than 140/90 mmHg in all patients, and to less than 130/80 mmHg in patients with diabetes mellitus or chronic kidney disease. Most patients will require more than one agent to achieve these target blood pressures. Antihypertensive therapy should be considered in all adult patients regardless of age (caution should be exercised in elderly patients who are frail). For adults without compelling indications for other agents, considerations for initial therapy should include thiazide diuretics, angiotensin- converting enzyme (ACE) inhibitors (in patients who are not black), long-acting calcium channel blockers (CCBs), angiotensin receptor blockers (ARBs) or beta-blockers (in those younger than 60 years of age). A combination of two first-line agents may also be considered as initial treatment of hypertension if systolic blood pressure is 20 mmHg above target or if diastolic blood pressure is 10 mmHg above target. The combination of ACE inhibitors and ARBs should not be used, unless compelling indications are present to suggest consideration of dual therapy. Agents appropriate for first-line therapy for isolated systolic hypertension include thiazide diuretics, long-acting dihydropyridine CCBs or ARBs. In patients with coronary artery disease, ACE inhibitors, ARBs or betablockers are recommended as first-line therapy; in patients with cerebrovascular disease, an ACE inhibitor/diuretic combination is preferred; in patients with proteinuric nondiabetic chronic kidney disease, ACE inhibitors or ARBs (if intolerant to ACE inhibitors) are recommended; and in patients with diabetes mellitus, ACE inhibitors or ARBs (or, in patients without albuminuria, thiazides or dihydropyridine CCBs) are appropriate first-line therapies. In selected high-risk patients in whom combination therapy is being considered, an ACE inhibitor plus a long-acting dihydropyridine CCB is preferable to an ACE inhibitor plus a thiazide diuretic. All hypertensive patients with dyslipidemia should be treated using the thresholds, targets and agents outlined in the Canadian lipid treatment guidelines. Selected patients with hypertension who do not achieve thresholds for statin therapy, but who are otherwise at high risk for cardiovascular events, should nonetheless receive statin therapy. Once blood pressure is controlled, low-dose acetylsalicylic acid therapy should be considered.
All recommendations were graded according to the strength of the evidence and voted on by the 63 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. All recommendations reported here achieved at least 80% consensus. These guidelines will continue to be updated annually.

The 2013 Canadian Hypertension Education Program recommendations for blood pressure measurement, diagnosis, assessment of risk, prevention, and treatment of hypertension.
We updated the evidence-based recommendations for the diagnosis, assessment, prevention, and treatment of hypertension in adults for 2013. This year's update includes 2 new recommendations. First, among nonhypertensive or stage 1 hypertensive individuals, the use of resistance or weight training exercise does not adversely influence blood pressure (BP) (Grade D). Thus, such patients need not avoid this type of exercise for fear of increasing BP. Second, and separately, for very elderly patients with isolated systolic hypertension (age 80 years or older), the target for systolic BP should be

The benefits of sportfish consumption and omega-3 fatty acid (omega3-FA) intake for cardiovascular risk factors were evaluated in a sample of 112 male fishers from the St. Lawrence River in the Montreal area during the 1996 winter and fall fishing seasons. A questionnaire on fishing practices and fish consumption was administered, and fasting blood samples were collected for lipid and phospholipid determination. Linear regression analyses, which considered the confounding effect of major risk factors, did not show any significant association between measured omega3-FAs or reported fish intake and blood lipids or blood pressure. This study is limited by its low statistical power due to the small sample size and the possibility that the fish eaten by the participants were low in omega3-FAs or that the participants diets contained foods high in cholesterol-raising fat.
