Status report -- Identifying equity-focussed interventions to promote healthy weights. / Rapport d'étape -- Recenser les interventions axées sur l'équité visant à promouvoir un poids santé.

INTRODUCTION: We developed screening criteria to identify population health interventions with an equity focus for inclusion on the Public Health Agency of Canada's Canadian Best Practices Portal. We applied them to the area of "healthy weights," specifically, obesity prevention. METHODS: We conducted a review of the literature and obtained input from expert external reviewers on changes to midstream environments. Interventions had to identify outcomes for groups with an underlying social disadvantage. We included papers with a focus on equity and vulnerable populations, intervention and/or evaluation studies, social determinants of health and healthy weights or obesity prevention. We then appraised the shortlisted studies for quality of evidence to determine eligibility for inclusion as promising practices on the Canadian Best Practices Portal. RESULTS: Few of the references reviewed passed the equity screening criteria (26 out of 2823 published papers reviewed, or 0.9%). Six (of the 26) interventions qualified as promising practices. CONCLUSION: The ability of the equity screening criteria to distinguish midstream-level interventions for obesity prevention suggests that the criteria have potential to be applied to other public health topics. What is most important about our work is that the Portal, which is no longer being updated but is still accessible, was broadened to include interventions with a focus on equity.

INTRODUCTION: Nous avons élaboré des critères de sélection pour recenser les interventions en santé populationnelle axées sur l'équité à intégrer dans le Portail canadien des pratiques exemplaires de l'Agence de la santé publique du Canada. Nous les avons appli-qués à la question du « poids santé ¼, plus précisément de la prévention de l'obésité. MÉTHODOLOGIE: Nous avons effectué une revue de la littérature et obtenu des commentaires d'examinateurs externes experts du domaine sur le thème des modifications des environnements intermédiaires. Les articles devaient décrire les résultats de l'intervention pour les groupes socialement désavantagés. Nous avons inclus les articles axés sur l'équité et les populations vulnérables, les études d'intervention ou d'évaluation, les déterminants sociaux de la santé et le poids santé ou la prévention de l'obésité. Nous avons ensuite évalué la qualité des données des études sélectionnées afin de déterminer si elles pouvaient être incluses dans le Portail canadien des pratiques exemplaires comme pratiques prometteuses. RÉSULTATS: Seul un petit nombre d'articles recensés ont répondu aux critères de sélection axés sur l'équité (26 articles publiés sur les 2 823 examinés, soit 0,9 %). Six interventions (sur 26) ont été considérées comme des pratiques prometteuses. CONCLUSION: Nos critères de sélection axés sur l'équité appliqués à la prévention de l'obésité nous ont permis de repérer des études sur les environnements intermédiaires, ce qui laisse penser que ces critères sont valables pour d'autres questions de santé publique. Surtout, grâce à nos travaux, le Portail s'est enrichi de la possibilité de recherche d'interventions axées sur l'équité.

The high burden of traumatic brain injury and comorbidities amongst homeless adults with mental illness.

OBJECTIVE: characterize the prevalence of self-reported head injury with loss of consciousness (LOC) and associated demographic, clinical and service use factors in a sample of homeless adults with mental illness. METHOD: Participants in the At Home/Chez Soi study were interviewed at the time of study enrollment regarding their history of head injuries, mental and physical health diagnoses and justice system and healthcare interactions. Sociodemographic and clinical data were also collected. RESULTS: Over half of the 2088 study respondents (52.6%, n = 1098) reported a history of head injury with a LOC, which was associated with several demographic, clinical and service use variables in this population. With respect to specific mental health conditions, a history of head injury with LOC was associated with higher odds of current depression (OR = 2.18, CI: 1.83-2.60), manic episode or hypomanic episode (OR = 1.91, CI: 1.45-2.50), PTSD (OR = 2.98, CI: 2.44-3.65), panic disorder (OR = 2.37, CI:1.91-2.93), mood disorder (OR = 1.78, CI: 1.40-2.26) and alcohol (OR = 2.09, CI: 1.75-2.49) and drug (OR = 1.73, CI: 1.46-2.06) misuse disorders, but reduced odds of having diagnosis of a psychotic disorder (OR = 0.63, CI: 0.53-0.76). A history of head injury with LOC was also associated with increased use of variety of services, including family medicine (OR = 1.33, CI: 1.12-1.59), criminal justice system (OR = 1.50, CI: 1.25-1.80) and the emergency department (OR = 1.03, CI: 1.01-1.05). CONCLUSIONS: Amongst homeless adults with mental illness having a history of head injuries with LOC was independently associated with various adverse outcomes. These individuals constitute a high-risk group who may benefit from specialized services.

Housing first improves residential stability in homeless adults with concurrent substance dependence and mental disorders.

OBJECTIVES: We examined the relationship between substance dependence and residential stability in homeless adults with current mental disorders 12 months after randomization to Housing First programs or treatment as usual (no housing or support through the study). METHODS: The Vancouver At Home study in Canada included 2 randomized controlled trials of Housing First interventions. Eligible participants met the criteria for homelessness or precarious housing, as well as a current mental disorder. Residential stability was defined as the number of days in stable residences 12 months after randomization. We used negative binomial regression modeling to examine the independent association between residential stability and substance dependence. RESULTS: We recruited 497 participants, and 58% (n = 288) met the criteria for substance dependence. We found no significant association between substance dependence and residential stability (adjusted incidence rate ratio = 0.97; 95% confidence interval = 0.69, 1.35) after adjusting for housing intervention, employment, sociodemographics, chronic health conditions, mental disorder severity, psychiatric symptoms, and lifetime duration of homelessness. CONCLUSIONS: People with mental disorders might achieve similar levels of housing stability from Housing First regardless of whether they experience concurrent substance dependence.

Civil society? What deliberative democrats can tell advocates about how to build public commitment to the health promotion agenda.

Closing the health inequity gap can be seen as an issue of justice, however what concretely best serves the interest of justice is in dispute. It is argued that standard policy-making mechanisms are inadequate to address this issue, and therefore more and better public dialogue is required. Drawing on deliberative democratic theory and practice, three public organizing considerations are offered: organizing within the state sphere, organizing within the public sphere, and using cross strategies. It is recommended that public resources be provided to involve the public in deliberations about population health promotion issues related to the wicked problem of health inequities.

Addressing the non-medical determinants of health: a survey of Canada's health regions.

BACKGROUND: The Canadian health system is undergoing reform. Over the past decade a prominent trend has been creation of health regions. This structural shift is concurrent with a greater emphasis on population health and the broad determinants of health. In parallel, there is a movement toward more intersectoral collaboration (i.e., collaboration between diverse segments of the health system, and between the health system and other sectors of society). The purpose of this exploratory study is to determine the self-reported level of internal action (within regional health authorities) and intersectoral collaboration around 10 determinants of health by regional health authorities across Canada. METHODS: From September 2003 to February 2004, we undertook a survey of regional health authorities in Canadian provinces (N = 69). Using SPSS 12.0, we generated frequencies for the self-reported level of internal and intersectoral action for each determinant. Other analyses were done to compare rural/suburban and urban regions, and to compare Western, Central and Eastern Canada. RESULTS: Of the 10 determinants of health surveyed, child development and personal health practices were self-reported by the majority of health regions to receive greatest attention, both internally and through intersectoral activities. Culture, gender and employment/working conditions received least attention in most regions. CONCLUSION: The exploratory survey results give us the first Canadian snapshot of health regions' activities in relation to the broad range of non-medical determinants of health. They provide a starting data set for baselining future progress, and for beginning deeper analyses of specific areas of action and intersectoral collaboration.

Predictors and outcomes of household food insecurity among inner city families with preschool children in Vancouver.

OBJECTIVES: The purposes of this study were to measure household food security and to determine its association with potential predictor variables related to household and community environments, as well as the relationship between household food insecurity and preschool children's nutritional status. METHODS: In this cross-sectional study, household food security was measured in a convenience sample of households (n=142) with children aged 2-5 years in Vancouver in March 2004. We assessed the association between environmental predictors and household food security status, adjusted for household income. Indicators of children's nutrition were compared between categories of household food security. RESULTS: Household food insecurity was associated with indicators of suboptimal health status in preschoolers. After controlling for household income, parents with less access to food of reasonable quality, fewer kitchen appliances and a lower rating of their cooking skills had greater odds of experiencing household food insecurity. IMPLICATIONS: Our study results support the need to test interventions involving collaborative efforts among government, social planners and public health practitioners to remove barriers to food security for families. Multiple measures, including opportunities to gain practical food skills and household resources that enable convenient preparation of nutrient-dense foods, could be examined. Our findings suggest the need for improved selection and quality at existing small stores and an increase in the number of food outlets in low-income neighbourhoods.

Homelessness and health in Canada: research lessons and priorities.

This article was for prepared for an international think-tank on reducing health disparities and promoting equity for vulnerable populations. Its purposes are to provide an overview of homelessness research and to stimulate discussion on strategic directions for research. We identified studies on homelessness, with an emphasis on Canadian research. Studies were grouped by focus and design under the following topics: the scope of homelessness, the health status of homeless persons, interventions to reduce homelessness and improve health, and strategic directions for future research. Key issues include the definition of homelessness, the scope of homelessness, its heterogeneity, and competing explanations of homelessness. Homeless people suffer from higher levels of disease and the causal pathways linking homelessness and poor health are complex. Efforts to reduce homelessness and improve health have included biomedical, educational, environmental, and policy strategies. Significant research gaps and opportunities exist in these areas. Strategic research will require stakeholder and community engagement, and more rigorous methods. Priorities include achievement of consensus on measuring homelessness, health status of the homeless, development of research infrastructure, and ensuring that future initiatives can be evaluated for effectiveness.

Assessment of communication barriers in community pharmacies.

This study identified previously reported facilitators and barriers to pharmacist-client communication and then evaluated their impact on the observed communication behaviors of pharmacists. Pharmacists (n = 100) completed a seven-page questionnaire collecting information on 11 variables that had been organized according to the Policy, Regulatory and Organizational Constructs in Educational and Ecological Development (PROCEDE) model as predisposing, enabling, or reinforcing of pharmacist communication with their clients. Demographic variables also were included. "Communication quality" served as the study's dependent variable, whereas pharmacist responses served as the independent variables. Communication quality scores for each pharmacist were obtained from the analysis of 765 audiorecordings of verbal exchanges occurring between the study pharmacists and their consenting clients during 4-hour, on-site observation periods. Four of the variables examined in the study were found to share a unique relationship with communication quality (pharmacists' attitude, year of graduation, adherence expectations, and outcome expectations). Hierarchical multiple regression analysis revealed that the variables measured in the questionnaire accounted for 23% of the variance in communication quality scores. Plausible explanations for why the study was unable to capture more of the variance in its proposed relationships and future areas for research are provided.

Implementation of provincial/territorial health goals in Canada.

During the past two decades, policy makers in most of Canada's provinces and territories developed broad population-level goal statements about desired health or health and social outcomes. The health goals development process used in each province/territory has been described in government documents and studied by a small number of researchers. However, there is a lack of published research examining the implementation and use of the health goals since they were developed. To begin to fill this gap, we conducted a study between 1998 and 2000 that examined the implementation of provincial/territorial health goals in Canada. Our findings indicate that as the 1990s drew to a close, provincial/territorial health goals were not being used explicitly by policy makers at either provincial/territorial or regional levels in most provinces in Canada to guide health policy and program development, implementation, or evaluation. Instead, the majority of health ministry and regional policy makers were employing strategic/business plans that, at best, reflected or were similar to the original provincial/territorial health goals. Moreover, even though all provinces and the NWT/Nunavut had health goals associated with broad social, economic, and physical environment health determinants, regional-level policy makers were giving priority to health care system goals over all other types of goals. We discuss our findings in relation to studies about health goals in other countries, and we suggest implications that our findings have for both future research and health policy.

Using patient-driven computers to provide cost-effective prevention in primary care: a conceptual framework.

This paper initially presents a rationale for the cost-effectiveness of using patient-driven computers in primary care services. It specifically defines the concepts of prevention and primary care, prior to outlining the advantages of promoting the implementation of prevention practices in primary care. It argues that greater use of computer technology represents one means of cost-effectively optimizing the integration of prevention into routine primary care, and identifies an apparent disjuncture between the potential of computers and the limited success with which attempts to integrate them into routine primary care services have been met, as evidenced in the published international literature. Among several possible explanations for this disjuncture, such as a possible lack of precision with which computers identify at-risk patients, perceived high costs associated with computers and physicians' concerns about the inflexibility and the more impersonal nature of computer interactions, is the apparent failure of researchers to utilize well designed and empirically tested models in the planning, implementation and evaluation of computerized care. An outline for such an approach, utilizing the Precede-Proceed model of health promotion planning and the Diffusion of Innovations theory, is presented.

Social and political factors influencing the functioning of regional health boards in British Columbia (Canada).

Health reform is associated with changes in the way the health system works and in the roles of major stakeholders, such as governments, health professionals, and the lay public. This paper reviews the immediate relevance of these social and political elements to health boards, particularly those with lay board members; source documents include peer-reviewed articles, and government documents and news releases in Canada especially. Also presented are the perceptions of 130 regional health board members in British Columbia (BC), Canada, who responded to our 1996 survey questionnaire. Two sets of social and political factors are identified and discussed in this paper. The first set deals with the composition of health board members (qualifications, representation, and selection). Our findings suggest that there is now less attention focusing on the composition of health boards in BC. This may contribute to a re-focusing of attention on the boards' effectiveness in working with stakeholders and in influencing the health system. The other set of social and political factors deals with the relations of health boards with key stakeholder groups. The responses to our questionnaire suggest that the health boards in BC may have had some success in addressing the concerns of various stakeholder groups. However, the respondents also suggested that the stakeholder groups needed to be more understanding and involved in the regionalization (decentralization) process. Health boards that have lay representatives, including regional health authorities in Canada, face similar social and political factors immediate to their operation.

Challenges of citizen participation in regional health authorities.

Citizen participation has been included as part of health reform, often in the form of lay health authorities. In Canada, these authorities are variously known as regional health boards or councils. A set of challenges is associated with citizen participation in regional health authorities. These challenges relate to: differences in opinion about whether there should be citizen participation at all; differences in perception of the levels and processes of participation; differences in opinion with respect to the roles and responsibilities of health authority members; differences in opinion about the appropriate composition of the authorities; differences in opinion about the requisite skills and attributes of health authority members; having a good support base (staff, good information, board development); understanding and operationalizing various roles of the board (governance and policy setting) versus the board staff (management and administration); difficulties in ensuring the accountability of the health authorities; and measuring the results of the work and decisions of the health authorities. Despite these challenges, regional health authorities are gaining support as both theoretically sound and pragmatically based approaches to health-system reform. This review of the above challenges suggests that each of the concerns remains a significant threat to meaningful public participation.
