OBJECTIVE: To assess the efficacy of a school-based intervention programme to reduce the prevalence of overweight in 6 to 10-year-old children. DESIGN: Cluster-randomized, controlled study. SUBJECTS: A total of 3135 boys and girls in grades 1-4 were included in the study. METHODS: Ten schools were selected in Stockholm county area and randomized to intervention (n=5) and control (n=5) schools. Low-fat dairy products and whole-grain bread were promoted and all sweets and sweetened drinks were eliminated in intervention schools. Physical activity (PA) was aimed to increase by 30 min day(-1) during school time and sedentary behaviour restricted during after school care time. PA was measured by accelerometry. Eating habits at home were assessed by parental report. Eating disorders were evaluated by self-report. RESULTS: The prevalence of overweight and obesity decreased by 3.2% (from 20.3 to 17.1) in intervention schools compared with an increase of 2.8% (from 16.1 to 18.9) in control schools (P
To provide updated, evidence-based recommendations for the diagnosis and assessment of adults with hypertension.
The diagnosis of hypertension is dependent on appropriate blood pressure measurement, the timely assessment of serially elevated readings, the degree of blood pressure elevation, the method of measurement (office, ambulatory, home) and associated comorbidities. The presence of cardiovascular risk factors and target organ damage should be ascertained to assess global cardiovascular risk and determine the urgency, intensity and type of treatment required.
MEDLINE searches were conducted from November 2007 to October 2008 with the aid of a medical librarian. Reference lists were scanned, experts were contacted, and the personal files of authors and subgroup members were used to identify additional studies. Content and methodological experts assessed studies using prespecified, standardized evidence-based algorithms. Recommendations were based on evidence from peer-reviewed full-text articles only.
Recommendations for blood pressure measurement, criteria for hypertension diagnosis and follow-up, assessment of global cardiovascular risk, diagnostic testing, diagnosis of renovascular and endocrine causes of hypertension, home and ambulatory monitoring, and the use of echocardiography in hypertensive individuals are outlined. Key messages include continued emphasis on the expedited, accurate diagnosis of hypertension, the importance of global risk assessment and the need for ongoing monitoring of hypertensive patients to identify incident type 2 diabetes.
All recommendations were graded according to strength of the evidence and voted on by the 57 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. All recommendations were required to be supported by at least 70% of task force members. These guidelines will continue to be updated annually.
To update the evidence-based recommendations for the prevention and management of hypertension in adults for 2009.
For lifestyle and pharmacological interventions, evidence from randomized controlled trials and systematic reviews of trials was 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 lack of long-term morbidity and mortality data in this field. Progression of kidney dysfunction 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 2007 to August 2008 to update the 2008 recommendations. To identify additional published 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 less than 2300 mg (100 mmol)/day (and 1500 mg to 2300 mg [65 mmol to 100 mmol]/day in hypertensive patients); perform 30 min to 60 min of 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 (smaller than 102 cm for men and smaller than 88 cm for women); limit alcohol consumption to no more than 14 units per week in men or nine units per week in women; follow a diet that is reduced in saturated fat and cholesterol, and that emphasizes fruits, vegetables and low-fat dairy products, dietary and soluble fibre, whole grains and protein from plant sources; and consider stress management in selected individuals with hypertension. For the pharmacological management of hypertension, treatment thresholds and targets should be predicated on by the patient's global atherosclerotic risk, target organ damage and comorbid conditions. Blood pressure should be decreased to lower than 140/90 mmHg in all patients, and to lower than 130/80 mmHg in those 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, initial therapy should include thiazide diuretics. Other agents appropriate for first-line therapy for diastolic and/or systolic hypertension include angiotensin- converting enzyme (ACE) inhibitors (in patients who are not black), long-acting calcium channel blockers (CCBs), angiotensin receptor antagonists (ARBs) or beta-blockers (in those younger than 60 years of age). A combination of two first-line agents may also be considered as the initial treatment of hypertension if the systolic blood pressure is 20 mmHg above the target or if the diastolic blood pressure is 10 mmHg above the target. The combination of ACE inhibitors and ARBs should not be used. Other agents appropriate for first-line therapy for isolated systolic hypertension include long- acting dihydropyridine CCBs or ARBs. In patients with angina, recent myocardial infarction or heart failure, beta-blockers and ACE inhibitors 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. All hypertensive patients with dyslipidemia should be treated using the thresholds, targets and agents outlined in the Canadian Cardiovascular Society position statement (recommendations for the diagnosis and treatment of dyslipidemia and prevention of cardiovascular disease). Selected high-risk patients with hypertension who do not achieve thresholds for statin therapy according to the position paper should nonetheless receive statin therapy. Once blood pressure is controlled, acetylsalicylic acid therapy should be considered.
All recommendations were graded according to strength of the evidence and voted on by the 57 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. All recommendations reported here achieved at least 95% consensus. These guidelines will continue to be updated annually.

The present report highlights the key messages of the 2009 Canadian Hypertension Education Program (CHEP) recommendations for the management of hypertension and the supporting clinical evidence. In 2009, the CHEP emphasizes the need to improve the control of hypertension in people with diabetes. Intensive reduction in blood pressure (to less than 130/80 mmHg) in people with diabetes leads to significant reductions in mortality rates, disability rates and overall health care system costs, and may lead to improved quality of life. The CHEP recommendations continue to emphasize the important role of patient self-efficacy by promoting lifestyle changes to prevent and control hypertension, and encouraging home measurement of blood pressure. Unfortunately, most Canadians make only minor changes in lifestyle after a diagnosis of hypertension. Routine blood pressure measurement at all appropriate visits, and screening for and management of all cardiovascular risks are key to blood pressure management. Many young hypertensive Canadians with multiple cardiovascular risks are not treated with antihypertensive drugs. This is despite the evidence that individuals with multiple cardiovascular risks and hypertension should be strongly considered for antihypertensive drug therapy regardless of age. In 2009, the CHEP specifically recommends not to combine an angiotensin-converting enzyme inhibitor with an angiotensin receptor blocker in people with uncomplicated hypertension, diabetes (without micro- or macroalbuminuria), chronic kidney disease (without nephropathy [micro- or overt proteinuria]) or ischemic heart disease (without heart failure).

Herein, updated evidence-based recommendations for the diagnosis, assessment, prevention, and treatment of hypertension in Canadian adults are detailed. For 2014, 3 existing recommendations were modified and 2 new recommendations were added. The following recommendations were modified: (1) the recommended sodium intake threshold was changed from = 1500 mg (3.75 g of salt) to approximately 2000 mg (5 g of salt) per day; (2) a pharmacotherapy treatment initiation systolic blood pressure threshold of = 160 mm Hg was added in very elderly (age = 80 years) patients who do not have diabetes or target organ damage (systolic blood pressure target in this population remains at
Research with Pride (RwP) was a community-student collaborative initiative to promote and build capacity for community-based research exploring health and wellness in lesbian, bisexual, trans and queer (LGBTQ) communities. The event took place at University of Toronto's Dalla Lana School of Public Health (DLSPH) in September 2009, and engaged over 100 students, community members and academic researchers in a full day of discussion, learning and networking. RwP was initiated by a group of graduate students in Health Promotion who identified a gap in resources addressing LGBTQ health, facilitating their further learning and work in this area. By engaging in a partnership with a community service organization serving LGBTQ communities in downtown Toronto, RwP emerges as a key example of the role of community-student partnerships in the pursuit of LGBTQ health promotion. This paper will describe the nature of this partnership, outline its strengths and challenges and emphasize the integral role of community-student partnerships in health promotion initiatives.
The development of knowledge for health promotion requires an effective mechanism for collaboration between academics, practitioners, and policymakers. The challenge is better to understand the dynamic and ever-changing context of the researcher-practitioner-policymaker-community relationship.
The aims were to explore the factors that foster Academic Practice Policy (APP) partnerships, and to systematically and transparently to review three cases.
Three partnerships were included: Power and Commitment-Alcohol and Drug Prevention by Non-Governmental Organizations in Sweden; Healthy City-Social Inclusion, Urban Governance, and Sustainable Welfare Development; and Empowering Families with Teenagers-Ideals and Reality in Karlskoga and Degerfors. The analysis includes searching for evidence for three hypotheses concerning contextual factors in multi-stakeholder collaboration, and the cumulative effects of partnership synergy.
APP partnerships emerge during different phases of research and development. Contextual factors are important; researchers need to be trusted by practitioners and politicians. During planning, it is important to involve the relevant partners. During the implementation phase, time is important. During data collection and capacity building, it is important to have shared objectives for and dialogues about research. Finally, dissemination needs to be integrated into any partnership. The links between process and outcomes in participatory research (PR) can be described by the theory of partnership synergy, which includes consideration of how PR can ensure culturally and logistically appropriate research, enhance recruitment capacity, and generate professional capacity and competence in stakeholder groups. Moreover, there are PR synergies over time.
The fundamentals of a genuine partnership are communication, collaboration, shared visions, and willingness of all stakeholders to learn from one another.
This article presents a programme for cardiovascular health for 9 to 12 years old children, called "Healthy Heart" Saint-Louis du Parc and carried out in low socioeconomic and multiethnic part of Montreal, Quebec, Canada. These five years programme targets were more both spheres: school and community (leisure centre, ethnocultural centre, groceries and other places). We develop the objectives, the conceptual models underlying to the programme, the perspective of work, the infrastructure of the programme: its staff and financing, the partnerships and the structure organising. Then we present the various interventions carried out along the period and so a description of many evaluations. At last, we discuss about the programme continuation.
Lowe and Chan's proposal for the development of common work environment metrics is long overdue. The authors' healthy work environment (HWE) framework is evidence based and illustrates the relationships between HWEs and organizational-level outcomes in a succinct yet comprehensive manner. The challenges we face in implementing their framework are related not so much to a fear of change but to a willingness to engage with multiple stakeholders and levels of government in coordinating our efforts. To date, we have lacked, at the policy level, a belief that HWEs can reduce operating costs, improve human resource utilization and, ultimately, lead to higher-quality patient care. We need a framework that will allow us to compare organizational performance in the area of health human resources in the same manner as we compare organizational outcomes in other areas. Such comparisons would allow us to further our understanding of the relationships among care providers, workplaces and organizational outcomes.
In order to achieve cardiovascular health for all Canadians, the ACHIC (Achieving Cardiovascular Health in Canada) partnership advocates that health promotion for healthy lifestyles be incorporated into practice, and that the consistent messages and professional skills required to motivate patients and the public be acquired through interprofessional education and development. Professional education specialists are essential members of health care promotion teams with expertise to develop educational interventions that impact behaviours of health professionals and subsequent patient outcomes. Continuing medical education (CME) is in evolution to continuing professional development (CPD), and then to continuing inter-professional development (CID). Providers of health promotion, public health, and health care can work with health educators to complete the cascade of learning, change in practice, and improvement in patient outcomes. The Canadian health care system can empower Canadians to achieve cardiovascular health, the most important health challenge in the 21st century.
