Old myths, new myths: challenging myths in public health.

Myths are widely held beliefs and are frequently perpetuated through telling and retelling. We examined 10 myths in public health research and practice. Where possible, we traced their origins, interrogated their current framing in relation to the evidence, and offered possible alternative ways of thinking about them. These myths focus on the nature of public health and public health interventions, and the nature of evidence in public health. Although myths may have some value, they should not be privileged in an evidence-informed public health context.

"The magic is in the mix": lessons from research capacity building in the Canadian tobacco control community, 2000-2010.

Global public health issues, including tobacco use, will be addressed most effectively if informed by relevant evidence. Additional capacity is needed to undertake and sustain relevant and rigorous research that will inform and enable learning from interventions. Despite the undisputed importance of research capacity building (RCB), there is little evidence about how to create relevant capacities. RCB for tobacco control in Canada from 2000-2010 offers a rich experience from which to learn. Lessons were derived using structured data collection from seven capacity-building initiatives and an invitational workshop, at which reflections on major contributions and lessons learned were discussed by initiative leads. Ten years of RCB for tobacco control in Canada revealed the importance of a) taking an organic approach to RCB, b) targeting and sustaining investments in a mix of RCB activities, c) vision and collaborative leadership at organizational and initiative levels, d) a focus on building community, and e) studying capacity building. The experience also provided tangible examples of RCB initiatives and how independent investments can be linked to create a coherent approach. Looking ahead, promising directions may include positioning RCB within a broader context of "field building", focusing on practical approaches to sustainability, and enhancing research on RCB.

Population and public health ethics in Canada: a snapshot of current national initiatives and future issues.

To date, some work has been undertaken to define a code and stewardship framework for public health ethics. However, gaps in our understanding and application of ethics to the field of population and public health (PPH) remain. This paper presents the approach to building capacity for PPH ethics by three national-level organizations: the Canadian Institutes of Health Research-Institute of Population and Public Health, the National Collaborating Centre for Healthy Public Policy, and the Public Health Agency of Canada. By first looking at each of the organizations' respective activities and then across organizations, we synthesize our common approaches, highlight future directions and pose questions aimed at stimulating dialogue about the role of, and challenges confronting, the emerging field of PPH ethics in Canada.

An examination of the relationship between municipal smoke-free bylaw strength and the odds of being a former smoker.

OBJECTIVE: The purpose of this study was to examine the relationship between municipal no-smoking bylaw strength and the odds of being a former smoker. METHODS: Data from Statistics Canada's Canadian Community Health Survey (Cycle 1.1, 2001) and a validated bylaw scoring scheme (2001) were linked and analyzed to determine whether the odds of being a former smoker were related to the strength of no-smoking bylaws in municipalities that had been matched for potentially confounding factors. The sample consisted of ever smokers (current and former smokers) from Ontario municipalities that did not have a no-smoking bylaw, or had a fully implemented no-smoking bylaw before September 2000. Data were analyzed using a Mantel-Haenszel Chi-square test and a logistic regression. RESULTS: The results from the Mantel-Haenszel (OR = 0.94, 95% CI 0.80-1.12) and logistic regression analyses (OR = 0.95, 95% CI 0.82-1.11) did not find support for the hypothesis that living in a municipality with a strong no-smoking bylaw would increase the odds of being a former smoker. DISCUSSION: Findings were inconsistent with previous studies that have found no-smoking restrictions in homes, workplaces and public places increase the odds that smokers attempt and succeed in quitting smoking. However, results from this study must be interpreted with caution because of the cross-sectional design and limited control of potentially important covariates.
