Canada: a land of missed opportunity for addressing the social determinants of health

Risk of premature mortality due to smoking, alcohol use, obesity and physical activity varies by income: A population-based cohort study

Background

Premature deaths are a strong population health indicator. There is a persistent and widening pattern of income inequities for premature mortality. We sought to understand the combined effect of health behaviours and income on premature mortality in a large population-based cohort.

Methods

We analyzed a cohort of 121,197 adults in the 2005-2014 Canadian Community Health Surveys, linked to vital statistics data to ascertain deaths for up to 5 years following baseline. Information on household income quintile and mortality-relevant risk factors (smoking status, alcohol use, body mass index (BMI), and physical activity) was captured from the survey. Hazard ratios (HR) for combined income-risk factor groups were estimated using Cox proportional hazards models. Stratified Cox models were used to identify quintile-specific HR for each risk factor.

Results

For each risk factor, HR of premature mortality was highest in the lowest-income, highest-risk group. Additionally, an income gradient was seen for premature mortality HR for every exposure level of each risk factor. In the stratified models, risk factor HRs did not vary meaningfully between income groups. All findings were consistent in the unadjusted and adjusted models.

Conclusion

These findings highlight the need for targeted strategies to reduce health inequities and more careful attention to how policies and interventions are distributed at the population level. This includes targeting and tailoring resources to those in lower income groups who disproportionately experience premature mortality risk to prevent further widening health inequities.

Using self-reported health as a social determinants of health outcome: a scoping review of reviews

Reducing disease prevalence rather than promoting health has long been the objective of significant population health initiatives, such as the social determinants of health (SDH) framework. However, empirical evidence suggests that people with diagnosed diseases often answer the self-reported health (SRH) question positively. In pursuit of a better proxy to understand, measure and improve health, this scoping review of reviews examines the potential of SRH to be used as an outcome of interest in population health policies. Following PRISMA-ScR guidelines, it synthesizes findings from 77 review papers (published until 11 May 2022) and reports a robust association between SDH and SRH. It also investigates inconsistencies within and between reviews to reveal how variation in population health can be explained by studying the impact of contextual factors, such as cultural, social, economic and political elements, on structural determinants such as socioeconomic situation, gender and ethnicity. These insights provide informed hypotheses for deeper explorations of the role of SDH in improving SRH. The review detects several gaps in the literature. Notably, more evidence syntheses are required, in general, on the pathway from contextual elements to population SRH and, in particular, on the social determinants of adolescents' SRH. This study reports a disease-oriented mindset in collecting, analysing and reporting SRH across the included reviews. Future studies should utilize the capability of SRH in interconnecting social, psychological and biological dimensions of health to actualize its full potential as a central public health measure.

Food insecurity during the COVID-19 pandemic who use drugs in Vancouver, Canada

OBJECTIVE

To examine prevalence and factors associated with food insecurity among people who use drugs (PWUD) during the first year of the COVID-19 pandemic and the overdose crisis.

DESIGN

This cross-sectional study employs multivariable logistic regression to identify factors associated with self-reported food insecurity.

PARTICIPANTS

PWUD who are part of three community-recruited cohorts.

SETTING

Interviews conducted in Vancouver, Canada, via phone between July and November 2020 in adherence to COVID-19 safety procedures.

RESULTS

Among 765 participants, including 433 (56·6 %) men, eligible for this study, 146 (19·1 %; 95 % CI: 16·3 %, 21·9 %) reported food insecurity in the past month. Of the participants reporting food insecurity, 114 (78·1 %) reported that their hunger levels had increased since the beginning of the pandemic. In multivariable analyses, factors independently and positively associated with food insecurity included: difficulty accessing health or social services (adjusted OR (AOR) = 2·59; 95 % CI: 1·60, 4·17); having mobility difficulties (AOR = 1·59; 95 % CI: 1·02, 2·45) and engaging in street-based income generation (e.g. panhandling and informal recycling) (AOR = 2·31; 95 % CI: 1·45, 3·65).

CONCLUSION

Approximately one in five PWUD reported food insecurity during this time. PWUD with mobility issues, who experienced difficulty accessing services and/or those engaged in precarious street-based income generation were more likely to report food insecurity. Food security is paramount to the success of interventions to prevent COVID-19 and drug toxicity deaths. These findings suggest a need for a more unified state response to food insecurity that prioritises and incorporates accessibility and autonomy of the communities they serve.

The Association Between Social Determinants of Health and Population Health Outcomes: Ecological Analysis

BACKGROUND

With the increased availability of data, a growing number of studies have been conducted to address the impact of social determinants of health (SDOH) factors on population health outcomes. However, such an impact is either examined at the county level or the state level in the United States. The results of analysis at lower administrative levels would be useful for local policy makers to make informed health policy decisions.

OBJECTIVE

This study aimed to investigate the ecological association between SDOH factors and population health outcomes at the census tract level and the city level. The findings of this study can be applied to support local policy makers in efforts to improve population health, enhance the quality of care, and reduce health inequity.

METHODS

This ecological analysis was conducted based on 29,126 census tracts in 499 cities across all 50 states in the United States. These cities were grouped into 5 categories based on their population density and political affiliation. Feature selection was applied to reduce the number of SDOH variables from 148 to 9. A linear mixed-effects model was then applied to account for the fixed effect and random effects of SDOH variables at both the census tract level and the city level.

RESULTS

The finding reveals that all 9 selected SDOH variables had a statistically significant impact on population health outcomes for ≥2 city groups classified by population density and political affiliation; however, the magnitude of the impact varied among the different groups. The results also show that 4 SDOH risk factors, namely, asthma, kidney disease, smoking, and food stamps, significantly affect population health outcomes in all groups (P<.01 or P<.001). The group differences in health outcomes for the 4 factors were further assessed using a predictive margin analysis.

CONCLUSIONS

The analysis reveals that population density and political affiliation are effective delineations for separating how the SDOH affects health outcomes. In addition, different SDOH risk factors have varied effects on health outcomes among different city groups but similar effects within city groups. Our study has 2 policy implications. First, cities in different groups should prioritize different resources for SDOH risk mitigation to maximize health outcomes. Second, cities in the same group can share knowledge and enable more effective SDOH-enabled policy transfers for population health.

Making the case for citizenship-oriented mental healthcare for youth in Canada

Purpose

Varying stakeholders have highlighted how recovery-oriented mental health services such as youth mental health services have traditionally focused on supporting individual resources to promote recovery (e.g., agency) to the exclusion of addressing structural issues that influence recovery (e.g. poverty). One response to this criticism has been work helping people with mental health problems recover a sense of citizenship and sense of belonging in their communities. Work on citizenship has yet to influence youth mental healthcare in Canada’s provinces and territories. This paper aims to highlight ways that youth mental healthcare can better help youth recover a sense of citizenship.

Design/methodology/approach

The arguments described in this paper were established through discussion and consensus among authors based on clinical experience in youth mental health and an understanding of Canada’s healthcare policy landscape, including current best practices as well as guidelines for recovery-oriented care by the Mental Health Commission of Canada.

Findings

Here, this study proposes several recommendations that can help young with mental health problems recover their sense of citizenship at the social, systems and service levels. These include addressing the social determinants of health; developing a citizenship-based system of care; addressing identity-related disparities; employing youth community health workers within services; adapting and delivering citizenship-based interventions; and connecting youth in care to civic-oriented organizations.

Originality/value

This paper provides the first discussion of how the concept of citizenship can be applied to youth mental health in Canada in multiple ways. The authors hope that this work provides momentum for adopting policies and practices that can help youth in Canada recover a sense of citizenship following a mental health crisis.

Drivers of medicalization in the Canadian Adult Obesity Clinical Practice Guidelines

The new Canadian Adult Obesity Clinical Practice Guidelines frame higher body weight as a chronic, relapsing disease requiring comprehensive medical treatment pathways. In this commentary, we will demonstrate how a process called pharmaceuticalization is informing the new guidelines. We join those questioning the normalization of industry and medical collaboration and interrogate whether the new guidelines meaningfully address stigma.

The impact of coalition characteristics on outcomes in community-based initiatives targeting the social determinants of health: a systematic review

Background

Coalitions are a popular mechanism for delivering community-based health promotion. The aim of this systematic review was to synthesize research that has quantitatively analyzed the association between coalition characteristics and outcomes in community-based initiatives targeting the social determinants of health. Coalition characteristics described elements of their structure or functioning, and outcomes referred to both proximal and distal community changes.

Methods

Authors searched six electronic databases to identify peer reviewed, published studies that analyzed the relationship between coalition characteristics and outcomes in community-based initiatives between 1980 and 2021. Studies were included if they were published in English and quantitatively analyzed the link between coalition characteristics and outcomes. Included studies were assessed for quality using the Joanna Briggs Institute analytical cross-sectional studies assessment tool.

Results

The search returned 10,030 unique records. After screening, 26 studies were included from six countries. Initiatives targeted drug use, health equity, nutrition, physical activity, child and youth development, crime, domestic violence, and neighbourhood improvement. Community outcomes measured included perceived effectiveness (n=10), policy, systems or environment change (n=9), and community readiness or capacity (n=7). Analyses included regression or correlation analysis (n=16) and structural equation or pathway modelling (n=10). Studies varied in quality, with a lack of data collection tool validation presenting the most prominent limitation to study quality. Statistically significant associations were noted between community outcomes and wide range of coalition characteristics, including community context, resourcing, coalition structure, member characteristics, engagement, satisfaction, group facilitation, communication, group dynamics, relationships, community partnership, and health promotion planning and implementation.

Conclusion

Existing literature demonstrates that coalition characteristics, including best practice health promotion planning and evaluation, influence community outcomes. The field of coalition research would benefit from more consistent description and measurement of coalition characteristics and outcomes, and efforts to evaluate coalitions in a wider range of countries around the world. Further research using empirical community outcome indicators, and methods that consider the interrelationship of variables, is warranted.

Equity at a time of pandemic

Health promotion has long aspired for a world where all people can live to their full potential. Yet, COVID-19 illuminates dramatically different consequences for populations bearing heavy burdens of systemic disadvantage within countries and between the Global South and Global North. Many months of pandemic is entrenching inequities that reveal themselves in the vastly differential distribution of hospitalization and mortality, for example, among racialized groups in the USA. Amplified awareness of the intimate relationship between health, social structures, and economy opens a window of opportunity to act on decades of global commitments to prioritize health equity. Choices to act (or not act) are likely to accelerate already vast inequities within and between countries as rapidly as the COVID-19 pandemic itself. Recognizing the inherently global nature of this pandemic, this article explores how determinants of equity are embedded in global responses to it, arguing that these determinants will critically shape our global futures. This article aims to stimulate dialogue about equity-centered health promoting action during a pandemic, using the Canadian Coalition for Global Health Research (CCGHR) Principles for Global Health Research to examine equity considerations at a time of pandemic. Attentiveness to power and the relationship between political economy and health are argued as central to identifying and examining issues of equity. This article invites dialogue about how equity-centered planning, decision-making and action could leverage this massive disruption to society to spark a more hopeful, just, and humane collective future.

Assessing resiliency in Canadians experiencing social vulnerability: Psychometric properties of the CUPS Resiliency Interview Schedule and Resiliency Questionnaire

Deficit models of care for clients experiencing social vulnerability have become increasingly unsustainable; and there is a shift towards models of care that promote and protect resiliency for lifelong health. We defined clients as socially vulnerable if they were living with poverty, mental health problems and addictions, disability, and social isolation. Scales to measure outcomes of resiliency-focused programming have limited reliability and have not been validated with vulnerable populations. The aim of this study was to develop and conduct preliminary psychometric assessment of two measures: CUPS (formerly Calgary Urban Project Society) Resiliency Interview Schedule (RIS) and Resiliency Questionnaire (RQ) for adults experiencing social vulnerability. To engage clients who were seeking integrated services at a social services agency, we developed the RIS and accessed data collected between April 2017 and December 2018. In a structured intake interview, the client and staff prioritised goals and identified resiliency in three domains: (a) economic, (b) social-emotional, and (c) health. On average, clients (N = 545) who completed the CUPS-RIS were 45.9 years old (SD = 12.62). For the CUPS-RIS, Cronbach's alphas at intake and outcome assessments were 0.80. Exploratory factor analysis demonstrated a four-factor solution with two unexpected results: executive functioning/self-regulation loaded with mental and physical health, and client education failed to load on any factor. We found significant improvements between client intake and outcome measurement points on eight of 12 sub-domains. As a brief self-report measure of resiliency, we developed the CUPS-RQ and accessed data collected between November 2018 and May 2019. Clients (N = 29) who completed the CUPS-RQ concurrently with the Resilience Research Centre-Adult Resilience Measure (RRC-ARM) were, on average, 42.46 years old (SD = 12.87). The CUPS-RQ was correlated with RRC-ARM, r = 0.819. In preliminary psychometric assessment, the CUPS-RIS and CUPS-RQ demonstrated satisfactory reliability and validity and show promise as measures of resiliency for agencies serving clients experiencing social vulnerability.

Desperately seeking reductions in health inequalities in Canada: Polemics and anger mobilization as the way forward?

Progress in reducing health inequalities through public policy action is difficult in nations identified as liberal welfare states. In Canada, as elsewhere, researchers and advocates provide governing authorities with empirical findings on the sources of health inequalities and document the lived experiences of those encountering these adverse health outcomes with the hope of provoking public policy action. However, critical analysis of the societal structures and processes that make improving the sources of health inequalities difficult-the quality and distribution of living and working conditions, that is the social determinants of health-identifies limitations in these approaches. Within this latter critical tradition, we consider-using household food insecurity in Canada as an illustration-how polemics and anger mobilization, usually absent in health inequalities research and advocacy-could force Canadian governing authorities to reduce health inequalities through public policy action. We explore the potential of using high valence terms such as structural violence, social death and social murder, which make explicit the adverse outcomes of health-threatening public policy to force government action. We conclude by outlining the potential benefits and threats posed by polemics and anger mobilization as means of promoting health equity.

In the midst of plenty: Experiences of food insecurity amongst women living with HIV in Vancouver, Canada

Globally, people living with HIV (PLWH) are disproportionately affected by food insecurity. Yet there is limited understanding of the impacts of food insecurity among cisgender and transgender women living with HIV (WLWH) in high-income countries. Thus, it is critical to examine the lived experiences of WLWH and food insecurity to inform policy and service provision. As part of the community-based SHAWNA (Sexual Health and HIV/AIDS: Women's Longitudinal Needs Assessment) study, we conducted 64 semistructured qualitative interviews with WLWH in Vancouver, Canada (2015-2017). Drawing on a socio-ecological framework, this analysis explores the lived experiences of navigating food security and health among WLWH in Metro Vancouver. Our findings indicate that WLWH relied heavily on food banks and other food-related supportive services. Despite the abundance of programs, access to nutritious foods remained difficult, and women often relied on processed foods that were more affordable and readily available. For many, food insecurity was exacerbated by unresponsive food services regulations that did not reflect the actual needs of food service users in terms of opening hours and locations, and a lack of nutritious food. Additionally, the absence of trauma-aware, women-centred and culturally responsive services, as well as, spatial and material barriers related to the recent loss of funding for HIV-specific support services, impeded food security among WLWH. Our findings emphasise that recognizing and addressing the social and structural disparities that exist for WLWH in high-income setting are essential for addressing food insecurity and ultimately optimal health among this population.

A Population-based Study of Grade 12 Academic Performance in Adolescents With Childhood-onset Chronic Rheumatic Diseases

OBJECTIVE

The aims of this study were (1) to compare grade 12 standardized test results of patients diagnosed with childhood-onset chronic rheumatic diseases (ChildCRD) and unaffected peers; and (2) to identify factors associated with test results of patients with ChildCRD and unaffected peers.

METHODS

This was a population-based retrospective cohort study. All patients with ChildCRD (juvenile arthritis and systemic autoimmune rheumatic diseases) from the only pediatric rheumatology center in Manitoba for birth cohorts January 1979 to December 1998 were linked to the provincial administrative databases containing records of healthcare use and education outcomes. Patients were matched by age, sex, and postal codes to their peers who did not have ChildCRD. The primary outcomes were the grade 12 Language Arts Achievement Index (LAI) and the Math Achievement Index (MAI) scores. ChildCRD, sociodemographic, and mental health factors were tested for their associations with LAI and MAI scores using multivariable linear regression.

RESULTS

Five hundred and forty-one patients with ChildCRD were matched to 2713 unaffected peers. Patients with ChildCRD had lower LAI and MAI scores compared to their peers. More patients with ChildCRD failed or did not take the language arts (51% vs 41%, P < 0.001) and math (61% vs 55%, P = 0.02) tests. On multivariable analysis, ChildCRD, lower socioeconomic status, younger maternal age at first childbirth, family income assistance, involvement with child welfare services, and mental health morbidities (between ChildCRD diagnosis and standardized testing), were associated with worse LAI and MAI results.

CONCLUSION

This population-based study showed that patients with ChildCRD performed less well than their peers on grade 12 standardized testing, independent of sociodemographic and mental health comorbidities.

Development of a foot care model to determine the risk of foot problems among homeless adults in Canada

Foot care is a common problem for homeless adults in cities, who often receive fragmented foot care services, resulting in increased foot problems, health complications, hospitalisation, limb removal and disabilities. Among the health factors that negatively affect the homeless, foot health is essential, but often neglected. This study employed a descriptive, cross-sectional research design to assess the foot care of homeless people and develop recommendations for clinical practice. Using Inlow's 60-s foot screening method, the foot conditions of a purposive sample of 65 homeless adults were examined in British Columbia, Canada, in 2019-2020. Descriptive and inferential statistics were used to analyse the data. Determinants, such as sex and years of homelessness significantly contributed to homeless individuals' risk of developing foot problems. Differences in perceived and observed foot problems were influenced by equitable access to social health and healthcare services. Foot assessment is not well-covered by homeless health services and should be implemented as part of the standard medical review of homeless patients. Furthermore, foot assessment should be conducted by healthcare professionals, rather than relying on the standard practice of service users' self-report. Finally, foot care should be based on tailoring assessments and interventions for the individualised needs of homeless service users. Future research must seek ways to integrate homeless individuals' voices in the development, implementation and evaluation of foot care services.

From millstones to milestones: Scaffolding a house of public health on political science foundations

BACKGROUND

We analyze the University of British Columbia's Department of Political Science's first course on health, "Global Politics and Health," to determine whether one course could inform political science students to tackle health issues. The major concept was global public health is politics writ large, as determinants of health are rooted in economic and social power. Course objectives encouraged student agency in ameliorating population health status.

METHODS

We use three surveys, with qualitative and quantitative components, to assess interest and knowledge of public health issues, and determine whether student agency increased as the course progressed.

RESULTS

We confirmed that political science develops an excellent foundation for the analysis of issues related to global public health status. One course can stimulate curiosity in health issues. Unexpectedly, we discovered that students' greatest learning outcome integrated personal, interpersonal, and scholarly analyses of health issues. This provided an avenue for students outside of the health sciences to frame mental health, sexuality, and other stigmatized subjects within scholarly discourse. After the course, virtually all students had developed a sense of agency, hope, and tools to understand the roots of mental and physical health. Following case studies on various countries, students quickly grasped the significant impact of politics and economics on people's health.

DISCUSSION

We recommend that political science departments offer courses that focus on health for all alongside existing courses on healthcare systems' politics. Furthermore, departments of public health may benefit from including political science courses as core elements of their curriculum to assist graduates in navigating the highly politicized infrastructure of public health. Both disciplines stand to gain from this interdisciplinary opportunity-- in the service of better health for all.

"The health equity curse": ethical tensions in promoting health equity

BACKGROUND

Public health (PH) practitioners have a strong moral commitment to health equity and social justice. However, PH values often do not align with health systems values, making it challenging for PH practitioners to promote health equity. In spite of a growing range of PH ethics frameworks and theories, little is known about ethical concerns related to promotion of health equity in PH practice. The purpose of this paper is to examine the ethical concerns of PH practitioners in promoting health equity in the context of mental health promotion and prevention of harms of substance use.

METHODS

As part of a broader program of public health systems and services research, we interviewed 32 PH practitioners.

RESULTS

Using constant comparative analysis, we identified four systemic ethical tensions: [1] biomedical versus social determinants of health agenda; [2] systems driven agendas versus situational care; [3] stigma and discrimination versus respect for persons; and [4] trust and autonomy versus surveillance and social control.

CONCLUSIONS

Naming these tensions provides insights into the daily ethical challenges of PH practitioners and an opportunity to reflect on the relevance of PH frameworks. These findings highlight the value of relational ethics as a promising approach for developing ethical frameworks for PH practice.

Trends in socioeconomic inequalities in premature and avoidable mortality in Canada, 1991-2016

BACKGROUND

Recent epidemiologic findings suggest that socioeconomic inequalities in health may be widening over time. We examined trends in socioeconomic inequalities in premature and avoidable mortality in Canada.

METHODS

We conducted a population-based repeated cohort study using the 1991, 1996, 2001, 2006 and 2011 Canadian Census Health and Environment Cohorts. We linked individual-level Census records for adults aged 25-74 years to register-based mortality data. We defined premature mortality as death before age 75 years. For each census cohort, we estimated age-standardized rates, risk differences and risk ratios for premature and avoidable mortality by level of household income and education.

RESULTS

We identified 16 284 045 Census records. Between 1991 and 2016, premature mortality rates declined in all socioeconomic groups except for women without a high school diploma. Absolute income-related inequalities narrowed among men (from 2478 to 1915 deaths per 100 000) and widened among women (from 1008 to 1085 deaths per 100 000). Absolute education-related inequalities widened among men and women. Relative socioeconomic inequalities in premature mortality widened progressively over the study period. For example, the relative risk of premature mortality associated with the lowest income quintile increased from 2.10 (95% confidence interval [CI] 2.02-2.17) to 2.79 (95% CI 2.66-2.91) among men and from 1.72 (95% CI 1.63- 1.81) to 2.50 (95% CI 2.36-2.64) among women. Similar overall trends were observed for avoidable mortality.

INTERPRETATION

Socioeconomically disadvantaged groups have not benefited equally from recent declines in premature and avoidable mortality in Canada. Efforts to reduce socioeconomic inequalities and associated patterns of disadvantage are necessary to prevent this pattern of widening health inequalities from persisting or worsening over time.

Improving the LGBTQ2S+ cultural competency of healthcare trainees: advancing health professional education

BACKGROUND

Lesbian, Gay, Bisexual, Trans, Queer, and Two-spirit (LGBTQ2S+) populations experience worse health outcomes compared to age-matched heterosexual and cisgender peers. Health professionals' deficient knowledge and negative attitudes can contribute to these inequities. Healthcare trainees report insufficient LGBTQS2+ cultural competence training.

METHODS

In this prospective, mixed-methods pre-post design, Atlantic Canadian health students were tested on knowledge, attitudes and self-reported behaviours towards LGBTQ2S+ populations in healthcare settings. Assessment included psychometric measurements and clinical cases involving normative and non-normative fictional patients. Participants were randomised to intervention or control groups. The intervention consisted of three training sessions lead by LGBTQ2S+ experts and elders from the community. The control group continued with usual training. Full assessment was repeated after training. We also held focus group discussions with students and faculty.

RESULTS

The intervention group significantly improved attitudes toward and knowledge of LGBTQ2S+ populations and changed relevant aspects of their performance in the simulated clinical situations. Focus groups identified key gaps in current local training.

CONCLUSIONS

Integrating specific training related to LGBTQ2S+ health within health professions programs is an important step toward improving these populations' accessibility to a competent, exhaustive and nurturing healthcare. Additional research on innovative means to expand and broaden the scope of our training is warranted.

Social and economic influences on disparities in the health of racial and ethnic group Canadian immigrants

OBJECTIVE

To examine social, economic, and migratory influences on the health of racial and ethnic minority groups in Canada, with a special focus on Caribbean immigrants.

METHODS

Combined annual cycles (2011-2016) of the Canadian Community Health Survey (CCHS) data totaling over 300,000 adult Canadian residents were aggregated. Descriptive statistics and multivariable logistic regression models were used to examine the prevalence and associated factors of (1) cardiovascular disease diagnosed by a healthcare professional, and (2) self-rated general health among racial and ethnic groups.

RESULTS

Caribbeans in general, Black and other non-White Canadians had significantly higher odds (adjusted for age/sex) of reporting any cardiovascular disease compared with White Canadians. Only non-Caribbean Blacks had higher odds of self-rated fair or poor general health compared with White Canadians. Multivariate logistic regression models revealed that after controlling for social and demographic factors, immigration status and years since migration, Caribbean non-Blacks and Black Caribbeans were at higher odds of having a doctor-reported cardiovascular health condition compared with White Canadians. Caribbean non-Blacks also had higher odds of fair or poor self-rated health than White Canadians.

CONCLUSION

The results of this study highlight the need for additional investigations of other potential influences on physical health statuses, especially among migrants and those of African ancestry who might be more prone to adverse health outcomes.

Quality of Life and Mental Well-Being: A Gendered Analysis of Persons Experiencing Homelessness in Canada

Homelessness has negative implications for mental well-being and quality of life. This paper identifies the quality of life variables that contribute to positive or negative wellbeing, reporting on a regression analysis from 343 individuals experiencing homelessness in Canada. Results indicate that a lack of sleep duration and quality reduced mental well-being for both genders, not having access to food and/or hygiene facilities decreased men's well-being, and engaging in illegal subsistence strategies, such as selling drugs, negatively impacted women's mental well-being. For persons experiencing homelessness, mental well-being and quality-of-life are gendered outcomes of their limited access to social determinants of health.

Income inequalities in the risk of potentially avoidable hospitaliation and readmission for chronic obstructive pulmonary disease: a population data linkage analysis

Introduction

Hospitalizations for ambulatory care sensitive conditions, of which chronic obstructive pulmonary disease (COPD) is among the most common, represent an indirect measure of the healthcare system to manage chronic disease. Research has pointed to disparities in various COPD-related outcomes between persons of lower versus higher income; however, few studies have examined the influence of patients' social context on potentially avoidable COPD admissions.

Objective

The research explores the use of linked population census and administrative health data to assess the influence of income inequalities on the risk of hospitalization and rehospitalization for COPD among Canadian adults.

Methods

This analysis utilizes data from the 2006 Census linked longitudinally to the 2006/07-2008/09 Discharge Abstract Database. Multiple logistic regressions were conducted to assess the independent influence of income inequality on the risks of hospitalization and of six-month readmission due to COPD among the population aged 30-69, controlling for age, sex, education and other sociodemographic characteristics.

Results

Compared with adults in the most affluent income quintile, the adjusted odds of COPD hospitalization were significantly greater in the 4th highest income quintile (OR: 1.38; 95%CI: 1.30-1.47), and peaked for those in the least affluent quintile (OR: 2.92; 95%CI: 2.77-3.09). Among individuals who had been hospitalized at least once for COPD in the study period, and compared with the most affluent group, the adjusted odds of readmission were highest in the least affluent group (OR: 1.39; 95%CI: 1.22-1.58).

Conclusions

Despite Canada's system of universal coverage for physician and hospital care, a clear income gradient in the risk of being hospitalized and, to some extent, rehospitalized for COPD, is found. Income inequalities may be contributing to excess hospitalizations, reinforcing the importance of integrating social and economic issues in primary care to meet the ambulatory needs of this population.

The Curated Food System: A Limiting Aspirational Vision of What Constitutes "Good" Food

In an effort to elucidate an aspirational vision for the food system and explore whether the characteristics of such a system inadvertently set unattainable standards for low-wealth rural communities, we applied discourse analysis to the following qualitative datasets: (1) interviews with food experts and advocates, (2) scholarly and grey literature, (3) industry websites, and (4) email exchanges between food advocates. The analysis revealed eight aspirational food system discourses: production, distribution, and infrastructure; healthy, organic, local food; behavioral health and education; sustainability; finance and investment; hunger relief; demand-side preferences; romanticized, community led transformations. Study findings reveal that of eight discourses, only three encompass the experiences of low-wealth rural residents. This aspirational food system may aggravate the lack of autonomy and powerlessness already experienced by low-wealth rural groups, perpetuate a sense of failure by groups who will be unable to reach the aspirational food vision, silence discourses that might question those that play a role in the inequitable distribution of income while sanctioning discourses that focus on personal or community solutions, and leave out other policy-based solutions that address issues located within the food system. Further research might explore how to draw attention to silenced discourses on the needs and preferences of low-wealth rural populations to ensure that the policies and programs promoted by food system experts mitigate poor diets caused by food insecurity. Further research is needed to inform policies and programs to mitigate food insecurity in low-wealth rural populations.

Narrative review of affinities and differences between the social determinants of oral and general health in Canada: establishing a common agenda

BACKGROUND

This article overviews Canadian work on the social determinants of oral and general health noting their affinities and differences.

METHODS

A literature search identified Canadian journal articles addressing the social determinants of oral health and/or oral health inequalities. Analysis identified affinities and differences with six themes in the general social determinants of health literature.

RESULTS

While most Canadian social determinants activity focuses on physical and mental health there is a growing literature on oral health-literature reviews, empirical studies and policy analyses-with many affinities to the broader literature. In addition, since Canada provides physical and mental health services on a universal basis, but does not do so for dental care, there is a special concern with the reasons behind, and the health effects-oral, physical and mental-of the absence of publicly financed dental care.

CONCLUSIONS

The affinities between the social determinants of oral health and the broader social determinants of health literature suggests the value of establishing a common research and action agenda. This would involve collaborative research into common social determinants of oral and general health and combined policy advocacy efforts to improve Canadians' living and working conditions as means of achieving health for all.

Depressive Symptoms and Father Involvement in Canada: Evidence from a National Study

Paternal involvement in instrumental and emotional parenting behaviours benefits families and children. While fathers have become more involved in childrearing over the past several decades, significant variability in paternal involvement with children remains. Yet, little work has focused on the facilitators and barriers to involved fathering and work in the Canadian context is particularly sparse. This study focuses on one potentially important factor, depressive symptoms, and its relationship with multiple dimensions of father involvement among Canadian men. Using national quantitative data from the Survey of Canadian Fathers-Enquête des Pères Canadiens (n = 2,099) and ordinary least squares regression models, we focus on the relationship between depressive symptoms and six measures of fathering behavior. Results indicate that depression is significantly associated with most behaviours, but these results diverge from studies in other countries and contexts. Overall, our findings underscore the importance of context-specific studies on parenting and the need for additional work on fathering and mental health in Canada.

Doing Occupational Justice: A Central Dimension of Everyday Occupational Therapy Practice

BACKGROUND.

The Canadian Association of Occupational Therapists (CAOT) and the American Occupational Therapy Association (AOTA) state that occupational justice is part of the domain of occupational therapy and that occupational justice is "an aspect of contexts and environments and an outcome of intervention" (AOTA, 2014, p. S9).

KEY ISSUES.

Despite the increasing focus on justice in the occupational therapy and the occupational science literature, many practitioners in traditional settings do not see its relevance to their everyday practice (Galvin, Wilding, & Whiteford, 2011) or have difficulty envisioning how to enact a justice-informed practice.

PURPOSE.

This paper demonstrates how occupational justice is germane to all settings of occupational therapy, and how it can be enacted at micro, meso, and macro levels of occupational therapy practice.

IMPLICATIONS.

We argue that occupational therapy is a justice-oriented profession at its core and will discuss how occupational justice can be enacted at all levels of practice.

Does "Rural" Always Mean the Same? Macrosocial Determinants of Rural Populations' Health in Poland

Rural areas, as well as urban ones, are not homogeneous in terms of social and economic conditions. Those surrounding large urban centers (suburban rural areas) act different roles than those located in remote areas. This study aims to measure the level of inequalities in social determinants of health (SDH) between two categories of rural areas. We pose the following research hypotheses: (hypothesis H1) rural areas in Poland are relatively homogenous in the context of SDH and (hypothesis H2) SDH affects life expectancies of rural residents. Based on data covering all rural territories, we found that rural areas in Poland are homogenous in SDH. We also find important determinants of health rooted in a demographic structure—the feminization index and a ratio of the working-age population. On the other hand, we cannot confirm the influence of commonly used SDH-GDP and unemployment rate.

Connecting knowledge with action for health equity: a critical interpretive synthesis of promising practices

Connecting knowledge with action (KWA) for health equity involves interventions that can redistribute power and resources at local, national, and global levels. Although there is ample and compelling evidence on the nature, distribution, and impact of health inequities, advancing health equity is inhibited by policy arenas shaped by colonial legacies and neoliberal ideology. Effective progress toward health equity requires attention to evidence that can promote the kind of socio-political restructuring needed to address root causes of health inequities. In this critical interpretive synthesis, results of a recent scoping review were broadened to identify evidence-informed promising practices for KWA for health equity. Following screening procedures, 10 literature reviews and 22 research studies were included in the synthesis. Analysis involved repeated readings of these 32 articles to extract descriptive data, assess clarity and quality, and identify promising practices. Four distinct kinds of promising practices for connecting KWA for health equity were identified and included: ways of structuring systems, ways of working together, and ways of doing research and ways of doing knowledge translation. Our synthesis reveals that advancing health equity requires greater awareness, dialogue, and action that aligns with the what is known about the causes of health inequities. By critically reflecting on dominant discourses and assumptions, and mobilizing political will from a more informed and transparent democratic exercise, knowledge to action for health equity can be achieved.

Health Equity in National Cancer Control Plans: An Analysis of the Ontario Cancer Plan

BACKGROUND

National cancer control plans (NCCPs) are important documents that guide strategic priorities in cancer care and plan for the appropriate allocation of resources based on the social, geographic and economic needs of a population. Despite the emphasis on health equity by the World Health Organization (WHO), few NCCPs have a focus on health equity. The Ontario Cancer Plan (OCP) IV, (2015 to 2019) is an example of an NCCP with clearly defined health equity goals and objectives.

METHODS

This paper presents a directed-content analysis of the OCP IV health equity goals and objectives, in light of the synergies of oppression analytical framework.

RESULTS

The OCP IV confines equity to an issue of access-to-care. As a result, it calls for training, funding, and social support services to increase accessibility for high-risk population groups. However, equity has a broader definition. And as such, it also implies that systematic differences in health outcomes between social groups should be minimal. This is particularly significant given that socially disadvantaged cancer patients in Ontario have distinctly poorer cancer-related health outcomes.

CONCLUSION

Health systems are seeking ways to reduce the health equity gap. However, to reduce health inequities which are socially-based will require a recognition of the living and working conditions of patients which influence risk, mortality and survival. NCCPs represent a way to politically advocate for the determinants of health which profoundly influence cancer risk, outcomes and mortality.

Assuming policy responsibility for health equity: local public health action in Ontario, Canada

In Canada's liberal welfare state the public is given little exposure by governmental authorities to the importance of promoting health equity through public policy action on the social determinants of health (SDoH). Not surprisingly, Canada lags in implementing health equity-enhancing public policy. In Ontario, Canada's most populous province, a local public health unit (PHU) took on the task of promoting health equity by developing the video animation Let's Start a Conversation about Health and Not Talk about Health Care at All. In the wake of this work, an additional 17 local PHUs (of 36) adapted it for local use. By placing these activities within Nutbeam's and de Leeuw's concepts of critical health literacy as an essential component of health promotion, we examine how these PHUs came to adopt the video, their intended uses, and supports and barriers encountered. These efforts by local PHUs to promote health equity through action on the SDoH have implications for those in jurisdictions where State attention to these issues is lacking.

Blending integrated knowledge translation with global health governance: an approach for advancing action on a wicked problem

BACKGROUND

The persistence of health inequities is a wicked problem for which there is strong evidence of causal roots in the maldistribution of power, resources and money within and between countries. Though the evidence is clear, the solutions are far from straightforward. Integrated knowledge translation (IKT) ought to be well suited for designing evidence-informed solutions, yet current frameworks are limited in their capacity to navigate complexity. Global health governance (GHG) also ought to be well suited to advance action, but a lack of accountability, inclusion and integration of evidence gives rise to politically driven action. Recognising a persistent struggle for meaningful action, we invite contemplation about how blending IKT with GHG could leverage the strengths of both processes to advance health equity.

DISCUSSION

Action on root causes of health inequities implicates disruption of structures and systems that shape how society is organised. This infinitely complex work demands sophisticated examination of drivers and disrupters of inequities and a vast imagination for who (and what) should be engaged. Yet, underlying tendencies toward reductionism seem to drive superficial responses. Where IKT models lack consideration of issues of power and provide little direction for how to support cohesive efforts toward a common goal, recent calls from the field of GHG may provide insight into these issues. Additionally, though GHG is criticised for its lack of attention to using evidence, IKT offers approaches and strategies for collaborative processes of generating and refining knowledge. Contemplating the inclusion of governance in IKT requires re-examining roles, responsibilities, power and voice in processes of connecting knowledge with action. We argue for expanding IKT models to include GHG as a means of considering the complexity of issues and opening new possibilities for evidence-informed action on wicked problems.

CONCLUSION

Integrated learning between these two fields, adopting principles of GHG alongside the strategies of IKT, is a promising opportunity to strengthen leadership for health equity action.

"It's not a food issue; it's an income issue": using Nutritious Food Basket costing for health equity advocacy

OBJECTIVES

Ontario's public health units (PHUs) face considerable challenges in addressing the social determinants of health, even though "reducing health inequities" is a primary population health outcome in the Ontario Public Health Standards (OPHS). Since 1998, the OPHS mandated PHUs to use the Nutritious Food Basket (NFB) protocol to document food costs, a requirement that was removed in 2018. This study examined how the NFB advanced health equity advocacy by Ontario PHUs, and why some have used this tool more strategically than others.

METHODS

Semi-structured qualitative phone interviews were conducted with 18 public health dietitians (PHDs) and three key informants between May and October 2017. Interviews were audio-recorded, transcribed, inductively coded, and analyzed.

RESULTS

The PHDs agreed that the NFB tool provides essential localized evidence of inadequate incomes for people living in poverty, and supports the health equity mandate of PHUs in Ontario. Factors that support NFB research and advocacy work include strong PHU leadership regarding health equity, participation in community coalitions, and engagement with Ontario Dietitians in Public Health (ODPH). Interviewees identified lack of support at the PHU level and lack of coordination of food insecurity work at the Ministry of Health as significant barriers to PHUs' use of the NFB to advance health equity mandates.

CONCLUSION

This study offers compelling evidence for reinstating NFB costing in the Ontario Public Health Standards as a mandatory requirement of PHUs. Without this requirement, the already-limited capacity of PHUs to advance health equity in Ontario will be further compromised.

Qualitative protocol for understanding the contribution of Australian policy in the urban planning, justice, energy and environment sectors to promoting health and health equity

INTRODUCTION

A well-established body of literature demonstrates that health and equity are strongly influenced by the consequences of governments' policy and resultant actions (or inactions) outside the health sector. Consequently, the United Nations, and its agency the WHO, have called for national leadership and whole-of-government action to understand and address the health impacts of policies in all sectors. This research responds to that call by investigating how policymaking in four sectors-urban planning, justice, energy and environment-may influence the social determinants of health and health equity (SDH/HE).

METHODS AND ANALYSIS

The research design is informed by a critical qualitative approach. Three successive stages are included in the design. The first involves analysing all strategic policy documents and selected legislative documents from the four sectors (n=583). The document analysis is based on a coding framework developed to identify alignment between the documents and the SDH/HE. Two policies that demonstrate good practice in regard to SDH/HE will be selected from each sector during the second stage for embedded case study analysis (total n=8). This is intended to illuminate which factors have supported recognition and action on SDH/HE in the selected policies. The third stage involves progressive theoretical integration and development to understand political and institutional facilitators and barriers to action on SDH/HE, both within and between sectors.

ETHICS AND DISSEMINATION

The research will provide much needed evidence about how coherent whole-of-government action on SDH/HE can be advanced and contribute knowledge about how health-enhancing policy activity in the four sectors may be optimised. Learnings from the research will be shared via a project advisory group, policy briefings, academic papers, conference presentations and research symposia. Ethics approval has been secured for the embedded case studies, which involve research participants.

Informal Recyclers' Health Inequities in Vancouver, BC

We explore informal recyclers' perceptions and experiences of the social determinants of health in Vancouver, Canada, and investigate the factors that contribute to the environmental health inequities they experience. Based on in-depth interviews with 40 informal recyclers and 7 key informants, we used a social determinants of health framework to detail the health threats that informal recyclers associated with their work and the factors that influenced their access to health-related resources and services. Our analysis reveals that the structural factors influencing environmental health inequities included insufficient government resources for low-income urbanites; the potential for stigma, clientization, and discrimination at some health and social service providers; and the legal marginalization of informal recycling and associated activities. We conclude that Vancouver's informal recyclers experience inequitable access to health-related resources and services, and they are knowledgeable observers of the factors that influence their own health and well-being.

Canada's universal health-care system: achieving its potential

Access to health care based on need rather than ability to pay was the founding principle of the Canadian health-care system. Medicare was born in one province in 1947. It spread across the country through federal cost sharing, and eventually was harmonised through standards in a federal law, the Canada Health Act of 1984. The health-care system is less a true national system than a decentralised collection of provincial and territorial insurance plans covering a narrow basket of services, which are free at the point of care. Administration and service delivery are highly decentralised, although coverage is portable across the country. In the setting of geographical and population diversity, long waits for elective care demand the capacity and commitment to scale up effective and sustainable models of care delivery across the country. Profound health inequities experienced by Indigenous populations and some vulnerable groups also require coordinated action on the social determinants of health if these inequities are to be effectively addressed. Achievement of the high aspirations of Medicare's founders requires a renewal of the tripartite social contract between governments, health-care providers, and the public. Expansion of the publicly funded basket of services and coordinated effort to reduce variation in outcomes will hinge on more engaged roles for the federal government and the physician community than have existed in previous decades. Public engagement in system stewardship will also be crucial to achieve a high-quality system grounded in both evidence and the Canadian values of equity and solidarity.

Can the sociology of social problems help us to understand and manage 'lifestyle drift'?

Lifestyle drift is increasingly seen as a barrier to broad action on the social determinants of health. The term is currently used in the population health literature to describe how broad policy initiatives for tackling inequalities in health that start off with social determinants (upstream) approach drift downstream to largely individual lifestyle factors, as well as the general trend of investing a the individual level. Lifestyle drift occurs despite the on-going efforts of public health advocates, such as anti-obesity campaigners, to draw attention to the social factors which shape health behavior and outcomes. In this article, we explore whether the sociology of social problems can help understand lifestyle drift in the context of obesity. Specifically, we apply Jamrozik and Nocella's residualist conversion model to the problem of obesity in order to explore whether such an approach can provide greater insight into the processes that underpin lifestyle drift and inform our attempts to mitigate it.

Health Equity Talk: Understandings of Health Equity among Health Leaders

INTRODUCTION

Reducing health inequities is a stated goal of health systems worldwide. There is widespread commitment to health equity among public health leaders and calls for reorientation of health systems towards health equity. As part of the Equity Lens in Public Health (ELPH) program of research, public health decision makers and researchers in British Columbia collaborated to study the application of a health equity lens in a time of health system renewal. We drew on intersectionality, complexity and critical social justice theories to understand how participants construct health equity and apply a health equity lens as part of public health renewal.

METHODS

15 focus groups and 16 individual semi-structured qualitative interviews were conducted with 55 health system leaders. Data were analyzed using constant comparative analysis to explore how health equity was constructed in relation to understandings and actions.

RESULTS

Four main themes were identified in terms of how health care leaders construct health equity and actions to reduce health inequities: (1) population health, (2) determinants of health, and (3) accessibility and (4) challenges of health equity talk. The first three aspects of health equity talk reflect different understandings of health equity rooted in vulnerability (individual versus structural), determinants of health (material versus social determinants), and appropriate health system responses (targeted versus universal responses). Participants identified that talking about health equity in the health care system, either inside or outside of public health, is a 'challenging conversation' because health equity is understood in diverse ways and there is little guidance available to apply a health equity lens.

CONCLUSIONS

These findings reflect the importance of creating a shared understanding of health equity within public health systems, and providing guidance and clarity as to the meaning and application of a health equity lens. A health equity lens for public health should capture both the production and distribution of health inequities and link to social justice to inform action.

Sustaining Engagement in Longitudinal Research With Vulnerable Families: A Mixed-Methods Study of Attrition

The aim of this mixed-methods study was to investigate attrition at the age 10-year follow-up in a study of vulnerable children and their families living with low income following a two-generation preschool program in Calgary, Alberta, Canada. Quantitative factors associated with attrition included: (a) food bank use; (b) unstable housing; (c) child welfare involvement; (d) unpartnered status; and (e) caregiver noncompletion of high school. Qualitative themes related to attrition included: (a) income and employment; (b) health; (c) unstable housing; (d) change of guardianship; (e) domestic violence; (f) work and time management challenges; and (g) negative caregiver-child relationships. Triangulation of quantitative and qualitative results occurred using Maslow's Hierarchy of Needs; families with unmet physiological, safety, belongingness and love needs, and esteem needs were more likely to attrite. Attrition in longitudinal studies with vulnerable families is complex, affected by frequently changing life circumstances, and struggles to access necessities of life. Strategies for retaining vulnerable families in longitudinal research are offered.

FACTORS INFLUENCING LAY AND PROFESSIONAL HEALTH WORKERS' SELF-EFFICACY IN IDENTIFICATION AND INTERVENTION FOR ALCOHOL, TOBACCO, AND OTHER SUBSTANCE USE DISORDERS IN KENYA

The global burden of substance use disorders (SUDs), including alcohol and tobacco, disproportionately affect low- and middle-income countries (LMICs), considering their rising disease burden and low service capacity. Nested within a Kenyan training program, this study explores factors associated with healthcare providers' self-efficacy to treat SUD. Surveys of 206 healthcare workers were used to perform regression and sensitivity analysis assessing various factors association with self-efficacy. Self-efficacy for SUD was lower in those practicing in public facilities and perceiving a need for alcohol use disorder (AUD) training; while higher self-efficacy correlated with a higher proportion of patients with AUD in one's setting, access to mental health worker support, cannabis use at a moderate risk level, and belief that AUD is manageable in outpatient settings. Increasing awareness about SUD prevalence, identification, and treatment skills could improve the self-efficacy of LMICs' health care providers and therefore the willingness to implement more services for patients with SUDs.

Contested Practice: Political Activism in Nursing and Implications for Nursing Education

Canadian nurses have a social mandate to address health inequities for the populations they serve, as well as to speak out on professional and broader social issues. Although Canadian nursing education supports the role of nurses as advocates for social justice and leadership for health care reform, little is known about how nurse educators understand activism and how this translates in the classroom. A comparative life history study using purposeful sampling and a critical feminist lens was undertaken to explore political activism in nursing and how nurse educators foster political practice among their students. Findings from interviews and focus groups with 26 Ontario nurse educators and nursing students suggested that neoliberal dynamics in both the practice setting and in higher education have constrained nurses' activist practice and favour a technical rational approach to nursing education. Implications and strategies to inspire political action in nursing education are discussed.

Taking stock of the social determinants of health: A scoping review

BACKGROUND

In recent decades, the social determinants of health (SDOH) has gained increasing prominence as a foundational concept for population and public health in academic literature and policy documents, internationally. However, alongside its widespread dissemination, and in light of multiple conceptual models, lists, and frameworks, some dilution and confusion is apparent. This scoping review represents an attempt to take stock of SDOH literature in the context of contemporary population and public health.

METHODS

We conducted a scoping review to synthesize and map SDOH literature, informed by the methods of Arksey and O'Malley (2005). We searched 5 academic and 3 grey literature databases for "social determinants of health" and "population health" or "public health" or "health promotion," published 2004-2014. We also conducted a search on "inequity" or "inequality" or "disparity" or "social gradient" and "Canad*" to ensure that we captured articles where this language was used to discuss the SDOH. We included articles that discussed SDOH in depth, either explicitly or in implicit but nuanced ways. We hand-searched reference lists to further identify relevant articles.

FINDINGS

Our synthesis of 108 articles showed wide variation by study setting, target audience, and geographic scope, with most articles published in an academic setting, by Canadian authors, for policy-maker audiences. SDOH were communicated by authors as a list, model, or story; each with strengths and weaknesses. Thematic analysis identified one theme: health equity as an overarching and binding concept to the SDOH. Health equity was understood in different ways with implications for action on the SDOH.

CONCLUSIONS

Among the vast SDOH literature, there is a need to identify and clearly articulate the essence and implications of the SDOH concept. We recommend that authors be intentional in their efforts to present and discuss SDOH to ensure that they speak to its foundational concept of health equity.

Food Insecurity Increases HIV Risk Among Young Sex Workers in Metro Vancouver, Canada

This research aimed to determine the effect of food insecurity on sexual HIV risk with clients among youth sex workers (YSWs) <30 years in Metro Vancouver, Canada. Data were drawn from a prospective community cohort of sex workers (2010-2013). We examined the independent relationship between YSWs' food insecurity and being pressured into sex without a condom by clients ("client condom refusal"). Of 220 YSWs, 34.5 % (n = 76) reported client condom refusal over the 3.5-year study period and 76.4 % (n = 168) reported any food insecurity. Adjusting for other HIV risk pathways, food insecurity retained an independent effect on client condom refusal (AOR 2.08, 95 % CI 1.23-3.51), suggesting that food insecurity is significantly associated with HIV risk among YSWs. This study indicates a critical relationship between food insecurity and HIV risk, and demonstrates YSWs' particular vulnerability. Public policies for food assistance as a harm reduction measure may be key to addressing this disparity.
