Using the intervention ladder to examine policy influencer and general public support for potential tobacco control policies in Alberta and Quebec. / Utilisation d'une échelle d'intervention pour analyser le soutien à d'éventuelles politiques de lutte contre le tabagisme de la part du grand public et d'influenceurs en matière de politiques en Alberta et au Québec.

OBJECTIVE: To assess general public and policy influencer support for population-level tobacco control policies in two Canadian provinces. METHODS: We implemented the Chronic Disease Prevention Survey in 2016 to a census sample of policy influencers (n = 302) and a random sample of members of the public (n = 2400) in Alberta and Quebec, Canada. Survey respondents ranked their support for tobacco control policy options using a Likert-style scale, with aggregate responses presented as net favourable percentages. Levels of support were further analyzed by coding each policy option using the Nuffield Council on Bioethics intervention ladder framework, to assess its level of intrusiveness on personal autonomy. RESULTS: Policy influencers and the public considered the vast majority of tobacco control policy options as "extremely" or "very" favourable, although policy influencers in Alberta and Quebec differed on over half the policies, with stronger support in Quebec. Policy influencers and the public strongly supported more intrusive tobacco control policy options, despite anticipated effects on personal autonomy (i.e. for policies targeting children/youth and emerging tobacco products like electronic cigarettes). They indicated less support for fiscally based tobacco control policies (i.e. taxation), despite these policies being highly effective. CONCLUSION: Overall, policy influencers and the general public strongly supported more restrictive tobacco control policies. This study further highlights policies where support among both population groups was unanimous (potential "quick wins" for health advocates). It also highlights areas where additional advocacy work is required to communicate the population-health benefit of tobacco control policies.

Monitoring progress toward United Nations commitments: characteristics of Canadian legislation to promote tobacco control, physical activity and healthy eating. A descriptive study.

BACKGROUND: Legal interventions are important mechanisms for chronic disease prevention. Since Canadian laws to promote physical activity and healthy eating are growing, we compared the characteristics of legal interventions targeting physical activity and healthy eating with tobacco control laws, which have been extensively described. METHODS: We reviewed 718 federal, provincial and territorial laws promoting tobacco control, physical activity and healthy eating captured in the Prevention Policies Directory between spring 2010 and September 2017. We characterized the legislation with regard to its purpose, tools to accomplish the purpose, responsible authorities, target location, level of coerciveness and provisions for enforcement. RESULTS: Two-thirds (67.9%) of tobacco control legislation had a primary chronic disease prevention purpose (explicit in 5.3% of documents and implicit in 62.6%), and 29.5% had a secondary chronic disease prevention purpose. One-quarter (27.0%) of physical activity legislation had a primary chronic disease prevention purpose (explicit in 8.8% of documents and implicit in 18.1%), and 53.0% had a secondary chronic disease prevention purpose. In contrast, 69.3% of healthy eating legislation had no chronic disease prevention purpose. Tobacco control legislation was most coercive (restrict or eliminate choice), and physical activity and healthy eating legislation was least coercive (provide information or enable choice). Most tobacco control legislation (85.8%) included provisions for enforcement, whereas 47.4% and 24.8% of physical activity and healthy eating laws, respectively, included such provisions. Patterns in responsible authorities, target populations, settings and tools to accomplish its purpose (e.g., taxation, subsidies, advertising limits, prohibitions) also differed between legislation targeting tobacco control versus physical activity and healthy eating. INTERPRETATION: Legislative approaches to promote physical activity and healthy eating lag behind those for tobacco control. The results serve as a baseline for building consensus on the use of legislation to support approaches to chronic disease prevention to reduce the burden of chronic disease in Canadians.

Advancing Strategies for Agenda Setting by Health Policy Coalitions: A Network Analysis of the Canadian Chronic Disease Prevention Survey.

Health in all policies can address chronic disease morbidity and mortality by increasing population-level physical activity and healthy eating, and reducing tobacco and alcohol use. Both governmental and nongovernmental policy influencers are instrumental for health policy that modifies political, economic, and social environments. Policy influencers are informed and persuaded by coalitions that support or oppose changing the status quo. Empirical research examining policy influencers' contact with coalitions, as a social psychological exposure with health policy outcomes, can benefit from application of health communication theories. Accordingly, we analyzed responses to the 2014 Chronic Disease Prevention Survey for 184 Canadian policy influencers employed in provincial governments, municipalities, large workplaces, school boards, and the media. In addition to contact levels with coalitions, respondents' jurisdiction, organization, and ideology were analyzed as potential moderators. Calculating authority score centrality using network analysis, we determined health policy supporters to be more central in policy influencer networks, and theorized their potential to impact health policy public agenda setting via priming and framing processes. We discuss the implications of our results as presenting opportunities to more effectively promote health policy through priming and framing by coordinating coalitions across risk behaviors to advance a societal imperative for chronic disease prevention.

Mandatory weight loss during the wait for bariatric surgery.

Mandatory presurgical, behavior-induced weight loss, although not standard, is a relatively common practice among bariatric surgical clinics. We explore the patient's experience of this practice using phenomenology. We gathered experiential accounts from 7 individuals waiting to have the procedure at a large publically funded clinic in western Canada. In writing this article, we focused on four phenomenological themes: "just nod your head and carry on"-silencing through the ideal; waiting and weighing-promoting weight consciousness to the weight conscious; paying for surgical approval through weight loss; and presurgical weight loss and questioning the need for weight loss surgery altogether. We contrast the experiential findings with the clinical literature to question the impact and possible (unintended or unexpected) effects the practice might have, particularly on patients' lives. We situate this article within a larger discussion about the possible contribution of experiential knowledge to clinical guidelines, practices, and pedagogies.

Cancer beliefs and prevention policies: comparing Canadian decision-maker and general population views.

PURPOSE: The knowledge, attitudes, and beliefs of key policy influencers and the general public can support or hinder the development of public policies that support cancer prevention. To address gaps in knowledge concerning healthy public policy development, views on cancer causation and endorsement of policy alternatives for cancer prevention among government influencers (elected members of legislative assemblies and senior ministry bureaucrats), non-governmental influencers (school board chairs and superintendents, print media editors and reporters, and workplace presidents and senior human resource managers), and the general public were compared. METHODS: Two structured surveys, one administered to a convenience sample of policy influencers (government and non-governmental) and the other to a randomly selected sample of the general public, were used. The aim of these surveys was to understand knowledge, attitudes, and beliefs regarding health promotion principles and the priority and acceptability of policy actions to prevent four behavioral risk factors for cancer (tobacco use, alcohol misuse, unhealthy eating, and physical inactivity). Surveys were administered in Alberta and Manitoba, two comparable Canadian provinces. RESULTS: Although all groups demonstrated higher levels of support for individualistic policies (e.g., health education campaigns) than for fiscal and legislative measures, the general public expressed consistently greater support than policy influencers for using evidence-based policies (e.g., tax incentives or subsidies for healthy behaviors). CONCLUSIONS: These results suggest that Canadian policy influencers may be less open that the general public to adopt healthy public policies for cancer prevention, with potential detriment to cancer rates.

Understanding key influencers' attitudes and beliefs about healthy public policy change for obesity prevention.

OBJECTIVE: As overweight and obesity is a risk factor for chronic diseases, the development of environmental and healthy public policy interventions across multiple sectors has been identified as a key strategy to address this issue. METHODS: In 2009, a survey was developed to assess the attitudes and beliefs regarding health promotion principles, and the priority and acceptability of policy actions to prevent obesity and chronic diseases, among key policy influencers in Alberta and Manitoba, Canada. Surveys were mailed to 1,765 key influencers from five settings: provincial government, municipal government, school boards, print media companies, and workplaces with greater than 500 employees. A total of 236 surveys were completed with a response rate of 15.0%. RESULTS: Findings indicate nearly unanimous influencer support for individual-focused policy approaches and high support for some environmental policies. Restrictive environmental and economic policies received weakest support. Obesity was comparable to smoking with respect to perceptions as a societal responsibility versus a personal responsibility, boding well for the potential of environmental policy interventions for obesity prevention. CONCLUSIONS: This level of influencer support provides a platform for more evidence to be brokered to policy influencers about the effectiveness of environmental policy approaches to obesity prevention.

Measuring the progress of capacity building in the Alberta Policy Coalition for Cancer Prevention.

The Alberta Policy Coalition for Cancer Prevention (APCCP) represents practitioners, policy makers, researchers, and community organizations working together to coordinate efforts and advocate for policy change to reduce chronic diseases. The aim of this research was to capture changes in the APCCP's capacity to advance its goals over the course of its operation. We adapted the Public Health Agency of Canada's validated Community Capacity-Building Tool to capture policy work. All members of the APCCP were invited to complete the tool in 2010 and 2011. Responses were analyzed using descriptive statistics and t tests. Qualitative comments were analyzed using thematic content analysis. A group process for reaching consensus provided context to the survey responses and contributed to a participatory analysis. Significant improvement was observed in eight out of nine capacity domains. Lessons learned highlight the importance of balancing volume and diversity of intersectoral representation to ensure effective participation, as well as aligning professional and economic resources. Defining involvement and roles within a coalition can be a challenging activity contingent on the interests of each sector represented. The participatory analysis enabled the group to reflect on progress made and future directions for policy advocacy.

Restricting marketing to children: consensus on policy interventions to address obesity.

Obesity presents major challenges for public health and the evidence is strong. Lessons from tobacco control indicate a need for changing the policy and environments to make healthy choices easier and to create more opportunities for children to achieve healthy weights. In April 2011, the Alberta Policy Coalition for Chronic Disease Prevention convened a consensus conference on environmental determinants of obesity such as marketing of unhealthy foods and beverages to children. We examine the political environment, evidence, issues, and challenges of placing restrictions on marketing of unhealthy foods and beverages within Canada. We recommend a national regulatory system prohibiting commercial marketing of foods and beverages to children and suggest that effective regulations must set minimum standards, monitor compliance, and enact penalties for non-compliance.

Changes in dietary and physical activity risk factors for type 2 diabetes in Alberta youth between 2005 and 2008.

OBJECTIVE: Unhealthy dietary and physical inactivity patterns inspired many initiatives promoting healthy youth and healthy schools in Alberta between 2005 and 2008. The purpose of this study was to examine differences in the prevalence of lifestyle risk factors for type 2 diabetes (T2D) between two province-wide samples of Alberta adolescents (2005 and 2008). METHODS: The dietary and physical activity (PA) patterns of Alberta youth were assessed in two cross-sectional studies of grade 7-10 students, one in 2005 (n=4936) and one in 2008 (n=5091), using a validated web-survey. For each diabetes risk factor, participants were classified as either at risk or not at risk, depending on their survey results relative to cut-off values. Chi-square tests and logistic regression models were used to determine differences in risk factor prevalence between 2005 and 2008. RESULTS: Compared to 2005, mean BMI, energy intake, fat intake, glycemic index (GI) and glycemic load (GL) were lower in 2008 (p<0.05); and carbohydrate, protein, fibre and vegetable and fruit intakes were higher in 2008 (p<0.05). In 2008, a lower proportion of students were: overweight, obese, consuming high GI, high GL, high fat, low fibre, low veg/fruit intake (p<0.05). No differences existed in magnesium or PA levels between the two time points. CONCLUSIONS: Improvements were observed between 2005 and 2008 in terms of the proportion of adolescents having specific risk factors for T2D. The cause of these changes could not be determined. Continued monitoring of adolescent lifestyle habits and monitoring of exposure to health promotion programming is recommended.

Geography influences dietary intake, physical activity and weight status of adolescents.

Purpose. The purpose of this study was to assess rural and urban differences in the dietary intakes, physical activity levels and weight status of a large sample of Canadian youth in both 2005 and 2008. Materials and Methods. A cross-sectional study of rural and urban adolescents (n = 10, 023) in Alberta was conducted in both 2005 and 2008 using a web-based survey. Results. There was an overall positive change in nutrient intakes between 2005 and 2008; however, rural residents generally had a poorer nutrient profile than urban residents (P < .001). They consumed less fibre and a greater percent energy from saturated fat. The mean physical activity scores increased among rural youth between 2005 and 2008 (P < .001), while remaining unchanged among urban youth. Residence was significantly related to weight status in 2005 (P = .017), but not in 2008. Conclusion. Although there were small improvements in nutrient intakes from 2005 to 2008, several differences in the lifestyle behaviours of adolescents living in rural and urban areas were found. The results of this study emphasize the importance of making policy and program recommendations to support healthy lifestyle behaviours within the context of the environments in which adolescents live.

Body mass index and risk of cardiovascular disease, cancer and all-cause mortality.

OBJECTIVES: To determine the dose-response relationship between body mass index (BMI) and cause-specific mortality among Canadian adults. METHODS: The sample includes 10,522 adults 18-74 years of age who participated in the Canadian Heart Health Surveys (1986-1995). Participants were divided into 5 BMI categories (< 18.5, 18.5-24.9, 25-29.9, 30-34.9, and > or = 35 kg/m2). Multivariate-adjusted (age, sex, exam year, smoking status, alcohol consumption and education) hazard ratios for all-cause, cardiovascular disease (CVD) and cancer mortality were estimated using Cox proportional hazards regression. RESULTS: There were 1,149 deaths (402 CVD; 412 cancer) over an average of 13.9 years (range 0.5 to 19.1 years), and the analyses are based on 145,865 person-years. The hazard ratios (95% CI) across successive BMI categories for all-cause mortality were 1.25 (0.83-1.90), 1.00 (reference), 1.06 (0.92-1.22), 1.27 (1.07-1.51) and 1.65 (1.29-2.10). The corresponding hazard ratios for CVD mortality were 1.30 (0.60-2.83), 1.00 (reference), 1.57 (1.22-2.01), 1.72 (1.27-2.33) and 2.09 (1.35-3.22); and for cancer, the hazard ratios were 1.02 (0.48-2.21), 1.00 (reference), 1.14 (0.90-1.44), 1.34 (1.01-1.78) and 1.82 (1.22-2.71). There were significant linear trends across BMI categories for all-cause (p = 0.0001), CVD (p < 0.0001) and cancer mortality (p = 0.003). CONCLUSIONS: The results demonstrate significant relationships between BMI and mortality from all causes, CVD and cancer. The increased risk of all-cause, CVD and cancer mortality associated with an elevated BMI was significant at levels above 30 kg/m2; however, overweight individuals (BMI 25-29.9 kg/m2) also had an approximately 60% higher risk of CVD mortality.

Adolescent weight status and related behavioural factors: web survey of physical activity and nutrition.

Purpose. To identify whether non-overweight students were different from their overweight or obese peers with respect to diet, suboptimal meal behaviours, and physical activity using a self-administered web-based survey. Methods. 4097 adolescents living in Alberta, Canada completed Web-SPAN (Web Survey of Physical Activity and Nutrition). Students were classified as overweight or obese, and differences were described in terms of nutrient intakes, physical activity, and meal behaviours. Results. Non-overweight students consumed significantly more carbohydrate and fibre, and significantly less fat and high calorie beverages, and had a higher frequency of consuming breakfast and snacks compared to overweight or obese students. Both non-overweight and overweight students were significantly more active than obese students. Conclusions. This research supports the need to target suboptimal behaviours such as high calorie beverage consumption, fat intake, breakfast skipping, and physical inactivity. School nutrition policies and mandatory physical education for all students may help to improve weight status in adolescents.

Diet quality, nutrition and physical activity among adolescents: the Web-SPAN (Web-Survey of Physical Activity and Nutrition) project.

OBJECTIVE: To assess the overall diet quality of a sample of adolescents living in Alberta, Canada, and evaluate whether diet quality, nutrient intakes, meal behaviours (i.e. meal skipping and consuming meals away from home) and physical activity are related. DESIGN: A cross-sectional study design. Students completed the self-administered Web-Survey of Physical Activity and Nutrition (Web-SPAN). Students were classified as having poor, average or superior diet quality based on Canada's Food Guide to Healthy Eating (CFGHE). SETTING: One hundred and thirty-six schools (37 %) within forty-four public and private school boards (75 %) in Alberta, Canada. SUBJECTS: Grade 7 to 10 Alberta students (n 4936) participated in the school-based research. RESULTS: On average, students met macronutrient requirements; however, micronutrient and fibre intakes were suboptimal. Median CFGHE food group intakes were below recommendations. Those with poor diet quality (42 %) had lower intakes of protein, fibre and low-calorie beverages; higher intakes of carbohydrates, fat and Other Foods (e.g. foods containing mostly sugar, high-salt/fat foods, high-calorie beverages, low-calorie beverages and high-sugar/fat foods); a lower frequency of consuming breakfast and a higher frequency of consuming meals away from home; and a lower level of physical activity when compared with students with either average or superior diet quality. CONCLUSIONS: Alberta adolescents were not meeting minimum CFGHE recommendations, and thus had suboptimal intakes and poor diet quality. Suboptimal nutritional intakes, meal behaviours and physical inactivity were all related to poor diet quality and reflect the need to target these health behaviours in order to improve diet quality and overall health and wellness.

Baseline assessment of organizational capacity for health promotion within regional health authorities in Alberta, Canada.

This paper provides a baseline profile of organizational capacity for (heart) health promotion in Alberta's regional health authorities (RHAs); and examines differences in perceived organizational health promotion capacity specific to modifiable risk factors across three levels of staff and across capacity levels. Baseline data were collected from a purposive sample of 144 board members, senior/middle managers and service providers from 17 RHAs participating in a five-year time-series repeated survey design assessing RHA capacity for (heart) health promotion. Results indicate low levels of capacity to take health promotion action on the broader determinants of health and risk conditions like poverty and social support. In contrast, capacity for health promotion action specific to physiological and behavioural risk factors is considerably higher. Organizational "will" to do health promotion is noticeably more present than is both infrastructure and leadership. Both position held within an organization as well as overall level of organizational capacity appear to influence perceptions of organizational capacity. Overall, results suggest that organizational "will", while necessary, is inadequate on its own for health promotion implementation to occur, especially in regard to addressing the broader determinants of health. A combination of low infrastructure and limited leadership may help explain a lack of health promotion action.
