Child protection services and youth experiencing homelessness: Findings of the 2019 national youth homelessness survey in Canada

Youth leaving or being discharged from child protection services (CPS) are a particularly vulnerable population in Canada that could be at an increased risk of homelessness, which has many adverse consequences including declining physical and mental health, school disengagement, involvement with the justice system, and substance use disorders. In this paper, we examine the extent to which youth accessing homelessness services with a history of involvement with CPS differ from their peers who have not interacted with CPS using the 2019 Without a Home: The National Youth Homelessness Survey—which is by far the largest study ever administered in Canada on youth homelessness (n = 1375). This examination includes a diverse range of life circumstances and outcomes, including quality of life, relationships with friends and family, criminal records, education, and adverse childhood experiences (ACEs). Furthermore, controlling for demographic characteristics, we present risk factors that are likely to be correlated with youth homelessness, including ACEs and the CPS history, and conclude by discussing policy implications and proposing future research avenues.

COVID-19 epidemiology in Canada from January to December 2020: the pre-vaccine era

This paper summarizes COVID-19 disease epidemiology in Canada in the pre-vaccine era—from January through to December 2020. Canadian case numbers, risk factors, disease presentations (including severe and critical disease), and outcomes are described. Differences between provinces and territories in geography, population size and density, health demographics, and pandemic impact are highlighted. Key concepts in public health response and mitigation are reviewed, including masking, physical distancing, hand washing, and the promotion of outdoor interactions. Adequate investment in public health infrastructure is stressed, and regional differences in screening and testing strategies are highlighted. The spread of COVID-19 in Canadian workplaces, long-term care homes, and schools is described and lessons learned emphasized. The impact of COVID-19 on vulnerable populations in Canada—including Indigenous Peoples, ethnic minorities and newcomers, people who use drugs, people who are homeless, people who are incarcerated, and people with disabilities—is described. Sex and gender disparities are also highlighted. Author recommendations include strategies to reduce transmission (such as test–trace–isolate), the establishment of nationally standardized definitions and public reporting, the protection of high risk and vulnerable populations, and the development of a national strategy on vaccine allocation.

Can BCG be useful to mitigate the COVID-19 pandemic? A Canadian perspective.

There is ample evidence from in vitro, animal and human studies that the Bacillus Calmette-Guerin (BCG) vaccine epigenetically reprograms innate immunity to provide “off target” protection against pathogens other than mycobacteria. This process has been termed “trained immunity”. Although recent ecological studies suggested an association between BCG policies and the frequency or severity of COVID-19 in different countries, the interpretation of these results is challenging. For this reason, a case-control study aiming to test this hypothesis has been initiated in Quebec. Several phase III clinical trials are underway, including one in Canada, to assess the efficacy of BCG against SARS-CoV-2 infection (results expected in 2021). In the past, BCG has been widely used in Canada but current indications are restricted to high-risk individuals and communities experiencing TB outbreaks as well as for the treatment of bladder cancer. The potential implication of BCG as an interim measure to mitigate COVID-19 is the subject of widespread discussion in the scientific community and can be considered for the vulnerable population in Canada. To conclude, BCG vaccination should be placed on the agenda of research funding agencies, scientific advisory committees on immunization and federal/provincial/territorial public health authorities.

Access to Vision Services by Vulnerable Populations in Canada: A Scoping Review.

Vision impairment has a significant impact on quality of life. Seventy percent of existing vision impairment in Canada is estimated to be correctable with prescription glasses. The sizeable proportion of correctable vision impairment appears related to the barriers to access to vision care in Canada. The objective of this scoping review is to determine gaps in the understanding of barriers to accessing vision care for vulnerable populations in Canada. The Arksey and O'Malley methodological framework was adopted. Studies published in English between 2005 and September 2017 on access to primary vision care by vulnerable populations in Canada were reviewed. Electronic databases used included Ovid MEDLINE, Ovid EMBASE, SCOPUS, ProQuest, and CINAHL. The Behavioural Model of Health Services Use was used to elucidate gaps in the literature. To develop relevant policies around vision care, efforts should be made to assess all dimensions of access for vulnerable populations across Canada.

The need for Inuit parents’ perspectives on outdoor risky play

AbstractParents’ perspectives on their children’s outdoor risky play behaviours influence their children’s adoption of safety strategies and their children’s approach to risky and dangerous situations (Brussoni & Olsen, 2011). Over the past decade, researchers have explored many Canadian mothers’ and fathers’ perspectives on this topic; however, to date, there has been a lack of research on Indigenous parents’ perspectives, particularly those of Inuit parents. This lack of research means that Inuit families are unaccounted for in research used to create and promote safety policies and practices in Canada. The present research commentary is the first to address the urgent need for research on northern Canadian Inuit parents’ perspectives on outdoor risky play. Specifically, outdoor risky play is defined, and Inuit children’s outdoor play experiences are compared to non-Inuit children’s experiences. Further, Inuit children’s experiences of injury are discussed to further situate the dire need to work with the most vulnerable population in Canada – Inuit – in child injury prevention research.

‘And when a certain health issue happen, they try to cover it’: Stakeholder perspectives on the health of temporary foreign workers and their families

ABSTRACTThis study examines stakeholders’ perspectives on the health and well-being of temporary foreign workers (TFWs) and their families in Alberta, Canada. We used a critically informed qualitative methodology. We interviewed 13 stakeholders, including service providers and policy makers. Stakeholders involved in providing services to TFWs perceived that the workers experience (1) barriers in accessing mental health services, (2) mental health challenges, (3) family health challenges, (4) occupational health challenges, and (5) income and social status as a social determinant of health. Immigration and class status intersect to influence the health of this vulnerable population in Canada.

“It was kind of like if it happens it happens. It wasn’t planned, it wasn’t intentional”: Young mothers’ experiences with subsequent pregnancy in Ottawa, Canada

Young mothers constitute a vulnerable population in Canada. Teens with children are at significant risk of subsequent pregnancy, a dynamic that can exacerbate health, emotional, and socio-economic challenges. We aimed to understand better the dynamics shaping “rapid repeat pregnancy” among young mothers in Ottawa, explore young mothers’ subsequent pregnancy experiences, and identify how services could be improved in Canada’s capital. In 2016, we conducted in-depth interviews with 10 young mothers and semi-structured interviews with 10 key informants working with pregnant and parenting youth. We analyzed interviews for content and themes using a multi-phased, iterative process. Four major themes emerged: (1) young mothers often plan their pregnancies actively or passively; (2) violence before, during, and after pregnancy is common; (3) mental health and substance abuse issues shape pregnancy risk; and (4) becoming pregnant often serves as a source of motivation for young mothers. Our results further indicate that young mothers have difficulty finding youth-friendly, non-judgmental support services and that integrated, multidisciplinary services offering individually tailored support and building on women’s strengths will likely be more successful in helping young mothers prevent subsequent pregnancies. Increasing awareness about existing services and supporting efforts that approach teen pregnancy comprehensively and holistically appear warranted.

Prevalence and Predictors of Food Allergy in Canada: A Focus on Vulnerable Populations

Studies suggest that individuals of low education and/or income, new Canadians (immigrated <10 years ago), and individuals of Aboriginal identity may have fewer food allergies than the general population. However, given the difficulty in recruiting such populations (hereafter referred to as vulnerable populations), by using conventional survey methodologies, the prevalence of food allergy among these populations in Canada has not been estimated. To estimate the prevalence of food allergy among vulnerable populations in Canada, to compare with the nonvulnerable populations and to identify demographic characteristics predictive of food allergy. By using 2006 Canadian Census data, postal codes with high proportions of vulnerable populations were identified and households were randomly selected to participate in a telephone survey. Information on food allergies and demographics was collected. Prevalence estimates were weighted by using Census data to account for the targeted sampling. Multivariable logistic regression was used to identify predictors of food allergy. Of 12,762 eligible households contacted, 5734 households completed the questionnaire (45% response rate). Food allergy was less common among adults without postsecondary education versus those with postsecondary education (6.4% [95% CI, 5.5%-7.3%] vs 8.9% [95% CI, 7.7%-10%]) and new Canadians versus those born in Canada (3.2% [95% CI, 2.2%-4.3%] vs 8.2% [95% CI, 7.4%-9.1%]). There was no difference in prevalence between those of low and of high income or those with and without Aboriginal identity. Analysis of our data suggests that individuals of low education and new Canadians self-report fewer allergies, which may be due to genetics, environment, lack of appropriate health care, or lack of awareness of allergies, which reduces self-report.

An Examination of Marijuana Use Among a Vulnerable Population in Canada.

Although the perceived risk of cannabis has decreased over the last few years, the contribution of marijuana use to the burden of disease on society is significant. Globally, Indigenous peoples have rates of marijuana use that are significantly higher than that of the general population. Understanding patterns of use is fundamental to developing appropriate policy and programming strategies to improve health and well-being. This study examined the characteristics of respondents who had ever been frequent marijuana users (used more than once a week), among a cross-sectional sample of 340 people, aged 18 and over, from Kettle and Stony Point First Nation in Ontario, Canada. The research incorporated Aboriginal-specific measures, examining issues related to colonialism and racism. Logistic regression models were used to assess the extent that sociodemographic variables, body mass index, mental health (depression, anxiety), licit substance use (alcohol and tobacco), Historical Loss Scale, Childhood Trauma Scale, and Measure of Indigenous Racism Experience (MIRE) Interpersonal Racism Scale predicted ever having been a frequent marijuana user. Aboriginal-specific issues were not associated with marijuana use nor was marijuana use related to depression or anxiety. However, ever engaging in frequent marijuana use was reported by more than half of the sample and associated with being younger, male, and a smoker. The high prevalence of frequent marijuana use (53.2 %) suggests normalization of the substance that may indicate a potentially large public health problem.

Environmental health and vulnerable populations in Canada: mapping an integrated equity‐focused research agenda

The uneven distribution of environmental hazards across space and in vulnerable populations reflects underlying societal inequities. Fragmented research has led to gaps in comprehensive understanding of and action on environmental health inequities in Canada and there is a need to gain a better picture of the research landscape in order to integrate future research. This paper provides an initial assessment of the state of the environmental health research field as specifically focused on vulnerable populations in Canada. We present a meta‐narrative literature review to identify under‐integrated areas of knowledge across disciplinary fields. Through systematic searching and categorization, we assess the abstracts of a total of 308 studies focused on the past 30 years of Canadian environmental health inequity research in order to describe temporal, geographical, contextual and epistemological patterns.The results reveal that there has been significant growth in Canadian research documenting the uneven distributions and impacts of environmental hazards across locations and populations since the 1990s, but its focus has been uneven. Notably, there is a lack of research aimed at integrating evidence‐based and policy‐relevant evaluation of environmental health inequities and how they are created and sustained. Areas for future research are recommended including more interdisciplinary, multimethod and preventive approaches to resolve the environmental burden placed on vulnerable populations and to promote environmental health equity.

Researching reducing health disparities: Mixed-methods approaches

There is a pressing need for assessment and intervention research focused on reducing health disparities. In our research program, the use of mixed methods has enhanced assessment of the mediating impacts of social support on the health of vulnerable populations and enabled the design and testing of support interventions. This paper highlights the benefits and challenges of mixed methods for investigating inequities; and, illustrates the application of mixed methods in two exemplar studies focused on vulnerable populations in Canada. Qualitative methods fostered in-depth understanding of vulnerable populations' support needs, support resources, intervention preferences, and satisfaction with intervention strategies and impacts. Quantitative methods documented the effectiveness and outcomes of intervention strategies, and enhanced the reliability and validity of assessments and interventions. The researchers demonstrate that participatory strategies are needed to make studies more relevant to reducing health disparities, contextually appropriate, and empowering.
