A Systematic Review on Vaccine Hesitancy in Black Communities in Canada: Critical Issues and Research Failures

Prevalence and Correlates of Intimate Partner Violence Among Women and Men in Mexico: A Systematic Review and Meta-analysis

This article presents the first systematic review and meta-analysis of the prevalence and correlates of different forms of intimate partner violence (IPV) among women and men in Mexico. To identify studies, a comprehensive search strategy was developed and executed across 11 databases (Academic Search Complete, APA PsycInfo, CINAHL, Cochrane CENTRAL, Embase, International Bibliography of the Social Sciences, LILACS, MEDLINE, SciELO, Sociological Abstracts, Web of Science). From the 1,746 studies screened, 155 full-text articles were reviewed, and this systematic review included 27 studies involving 249,557 participants to determine the prevalence of physical, psychological, sexual, threats, and other forms of IPV, according to gender and other sociodemographic characteristics. Overall IPV prevalence was 16.4%, with significant differences across pregnant and non-pregnant women. Physical IPV prevalence was 14.7%, revealing higher rates in men (29.5%) compared to women (14.2%). Psychological IPV prevalence was 27.3% and sexual IPV was at 6.6%, with differences across evaluation periods. Threats and other IPV forms showed a prevalence rate of 14.2% and 21.5%. Meta-regression analyses included gender, education, marital status, rural residency, pregnancy, age, and evaluation period. This study demonstrates that IPV is a critical public health concern in Mexico, impacting both women and men. It shows the vulnerability of rural residents, youth, and pregnant women. However, understanding IPV complexities in Mexico requires nuanced considerations of demographic and situational contexts. Urgent initiatives from municipal, state, and federal governments are needed to combat IPV, focusing on prevention and support for affected individuals.

Rates and Factors Related to COVID-19 Vaccine Uptake in Racialized and Indigenous Individuals in Canada: The Deleterious Effect of Experience of Racial Discrimination

Racialized and Indigenous communities have been disproportionately affected by COVID-19 infections and mortality, driven by systemic socioeconomic inequalities. However, how these factors specifically influence COVID-19 vaccine uptake is not documented among racialized individuals in Canada. The present study aims to examine COVID-19 vaccine uptake rates and related factors among racialized and Indigenous communities compared to White people in Canada. In total, 41,931 individuals aged 16 and older, consisting mainly of Arab, Asian, Black, Indigenous, and White individuals, were randomly invited to participate from a panel of 420,000 Canadian households. A total of 4220 participants completed this cross-sectional survey study in October 2023. In total, 89.60% of participants were vaccinated: 2.38% received one dose, 31.45% received two doses, 33.46% received three doses, 18.86% received four doses, and 13.86% received five doses and more. There were significant differences according to racial and ethnic background in vaccine uptake (χ2 = 57.45, p < 0.001), with Indigenous and Black individuals having lower vaccination rates (83.54%, OR = 1.98% and 84.76%, OR = 2.16, p < 0.01) compared to White individuals (91.66%). Confidence in health authorities was positively associated with vaccine uptake (B = 0.62, p < 0.001). Conspiracy beliefs partially mediated this association (B = -0.13, p < 0.001). Racial discrimination attenuated vaccine uptake, even if respondents had confidence in health authorities (B = -0.08, p < 0.001). Vaccine uptake was lowest amongst Indigenous and Black communities, placing them at higher risk of severe COVID-19 infection. In addition to mistrust of public health authorities due to racism, racialized communities are affected by conspiracy beliefs that hinder COVID-19 vaccine uptake. A whole-of-society approach to address barriers to vaccine uptake among racialized populations, including wage disparities, racial discrimination, is needed to eliminate racial health disparities and increase vaccination rates in racialized communities.

Depression and suicidal ideation among Black individuals in Canada: mediating role of traumatic life events and moderating role of racial microaggressions and internalized racism

PURPOSE

Although suicidal ideation (SI) is a serious concern in Canada, its prevalence and related factors among Black individuals are poorly documented. Using data from the Mental Health of Black Communities in Canada project (BeCoMHeal), this study aimed to assess the prevalence of SI in Black individuals aged 15-40 years old in Canada, the mediating role of traumatic life events in the association between depression and SI, and the moderating role of racial microaggressions and internalized racism.

METHODS

Eight hundred and sixty participants aged between 15 and 40 years (Mage =24.96, SD = 6.29) completed the online questionnaire assessing sociodemographic data, depression symptoms, traumatic life events, racial microaggressions, internalized racism, and SI.

RESULTS

Findings showed that 25.7% of the participants reported having experienced SI (26.5% women, 22.7% men, 𝛘2 = 1.08, p = .299). The moderated-mediation model revealed that traumatic life events fully mediated the association between depression and SI (B = 0.12, p = .004; 95% CI, [0.04, 0.20]) and that racial microaggressions (B = - 0.03, p = .042; 95% CI [-0.07, - 0.00]) and internalized racism (B = 0.06, p = .006; 95% CI [0.02, 0.10]) moderated this relationship.

CONCLUSION

These findings underscore the importance of addressing racial microaggressions and internalized racism in therapy contexts among Black individuals to mitigate the potential negative impacts on their mental health. They also emphasize the need to develop effective, culturally sensitive, and racially adapted suicide prevention and intervention programs for Black communities in Canada.

Resilience throughout COVID-19: Unmasking the realities of COVID-19 and vaccination facilitators, barriers, and attitudes among Black Canadians

Black communities have suffered disproportionately higher numbers of COVID-19 cases and deaths in Canada. Recognizing the significance of supporting targeted strategies with vulnerable populations extends beyond the COVID-19 pandemic, as it addresses longstanding health disparities and promotes equitable access to healthcare. The present study investigated 1) experiences with COVID-19, 2) COVID-19's impact, and 3) factors that have influenced COVID-19 vaccine acceptance and uptake among stakeholders and partners from the Federation of Black Canadians' (FBC). We conducted semi-structured interviews with 130 individuals and four focus groups with FBC, including stakeholders and partners, between November 2021 and June 2022. The semi-structured interviews and focus group discussions were conducted virtually over Zoom and lasted about 45 minutes each. Conversations from interviews and focus groups were transcribed and coded professionally using team-based methods. Themes were developed using an inductive-deductive approach and defined through consensus. The deductive approach was based on Consolidated Framework for Implementation Research (CFIR) domains and constructs. First, regarding experiences with COVID-19, 36 codes were identified and mapped onto 13 themes. Prominent themes included 39 participants who experienced highly severe COVID-19 infections, 25 who experienced stigma, and 18 who reported long recovery times. Second, COVID-19 elicited lifestyle changes, with 23 themes emerging from 62 codes. As many as 97 participants expressed feelings of isolation, while 63 reported restricted mobility. Finally, participants discussed determinants that influenced their vaccination decisions, in which 46 barriers and four facilitators were identified and mapped onto nine overarching themes. Themes around the CFIR domains Individuals, Inner Setting, and Outer Setting were most prominent concerning vaccine adoption. As for barriers associated with the constructs limited available resources and low motivation, 55 (41%) and 46 (34%) of participants, respectively, mentioned them most frequently. Other frequently mentioned barriers to COVID-19 vaccines fell under the construct policies & laws, e.g., vaccine mandates as a condition of employment. Overall, these findings provide a comprehensive and contextually rich understanding of pandemic experiences and impact, along with determinants that have influenced participants' vaccination decisions. Furthermore, the data revealed diverse experiences within Black communities, including severe infections, stigma, and vaccine-related challenges, highlighting the importance of targeted interventions, support, and consideration of social determinants of health in addressing these effects.

COVID-19 vaccine mistrust, health literacy, conspiracy theories, and racial discrimination among a representative ethnically diverse sample in Canada: The vulnerability of Arab, Asian, Black, and Indigenous peoples

Despite increased risk of severe acute respiratory syndrome coronavirus 2 infections and higher rates of COVID-19-related complications, racialized and Indigenous communities in Canada have lower immunization uptake compared to White individuals. However, there is woeful lack of data on predictors of COVID-19 vaccine mistrust (VM) that accounts for diverse social and cultural contexts within specific racialized and Indigenous communities. Therefore, we sought to characterize COVID-19 VM among Arab, Asian, Black, and Indigenous communities in Canada. An online survey was administered to a nationally representative, ethnically diverse panel of participants in October 2023. Arabic, Asian, Indigenous, and Black respondents were enriched in the sampling panel. Data were collected on demographics, COVID-19 VM, experience of racial discrimination, health literacy, and conspiracy beliefs. We used descriptive and regression analyses to determine the extent and predictors of COVID-19 VM among racialized and Indigenous individuals. All racialized respondents had higher VM score compared to White participants. Among 4220 respondents, we observed highest VM among Black individuals (12.18; ±4.24), followed by Arabic (12.12; ±4.60), Indigenous (11.84; ±5.18), Asian (10.61; ±4.28), and White (9.58; ±5.00) participants. In the hierarchical linear regression analyses, Black participants, women, everyday racial discrimination, and major experience of discrimination were positively associated with COVID-19 VM. Effects of racial discrimination were mediated by addition of conspiracy beliefs to the model. Racialized and Indigenous communities experience varying levels of COVID-19 VM and carry specific predictors and mediators to development of VM. This underscores the intricate interaction between race, gender, discrimination, and VM that need to be considered in future vaccination campaigns.

Venous thromboembolism in Black COVID-19 patients in a minority context compared to White, Asian and other racialized patients: A systematic review and meta-analysis

IMPORTANCE

COVID-19 has disproportionately affected racialized populations, with particular impact among individuals of Black individuals. However, it is unclear whether disparities in venous thromboembolic (VTE) complications exist between Black individuals and those belonging to other racial groups with confirmed SARS-CoV2 infections.

OBJECTIVE

To summarize the prevalence and moderators associated with VTE among Black COVID-19 patients in minoritized settings, and to compare this to White and Asian COVID-19 patients according to sex, age, and comorbid health conditions (heart failure, cancer, obesity, hypertension).

DESIGN SETTING, AND PARTICIPANTS

A systematic search of MEDLINE, Embase, CINAHL and CENTRAL for articles or reports published from inception to February 15, 2023.

STUDY SELECTION

Reports on VTE among Black individuals infected with SARS-CoV2, in countries where Black people are considered a minority population group.

DATA EXTRACTION AND SYNTHESIS

Study characteristics and results of eligible studies were independently extracted by 2 pairs of reviewers. VTE prevalence was extracted, and risk of bias was assessed. Prevalence estimates of VTE prevalence among Black individuals with COVID19 in each study were pooled. Where studies provided race-stratified VTE prevalence among COVID19 patients, odds ratios were generated using a random-effects model.

MAIN OUTCOMES AND MEASURES

Prevalence of VTE, comprising of deep vein thrombosis and pulmonary embolism.

RESULTS

Ten studies with 66,185 Black individuals reporting the prevalence of COVID-19 associated VTE were included. Weighted median age of included studies was 47.60. Pooled prevalence of COVID-19 associated VTE was 7.2 % (95 % CI, 3.8 % - 11.5 %) among Black individuals. Among individuals with SARS-CoV2 infections, Black population had higher risks of VTE compared to their White (OR = 1.79, [95 % CI 1.28-2.53], p < .001) or Asian (OR = 2.01, [95 % CI, 1.14-3.60], p = .017) counterparts, or patients with other racial identities (OR = 2.01, [95 % CI, 1.39, 2.92]; p < .001).

CONCLUSIONS AND RELEVANCE

Black individuals with COVID-19 had substantially higher risk of VTE compared to White or Asian individuals. Given racial disparities in thrombotic disease burden related to COVID-19, medical education, research, and health policy interventions are direly needed to ensure adequate disease awareness among Black individuals, to facilitate appropriate diagnosis and treatment among Black patients with suspected and confirmed VTE, and to advocate for culturally safe VTE prevention strategies, including pre-existing inequalities to the COVID-19 pandemic that persist after the crisis.

Challenges of determining the relative contribution of determinants of health on population health: a Canadian perspective

This article investigates the source of frequently cited data regarding the relative contribution of determinants of health to population health in Canada. It critically discusses the imperative for such national or regional data in policymaking, and the challenges and limitations of this approach.

Racial discrimination in healthcare services among Black individuals in Canada as a major threat for public health: its association with COVID-19 vaccine mistrust and uptake, conspiracy beliefs, depression, anxiety, stress, and community resilience

OBJECTIVES

To examine the prevalence of major racial discrimination (MRD) in healthcare services and its association with COVID-19 vaccine mistrust and uptake, conspiracy theories, COVID-19-related stressors, community resilience, anxiety, depression, and stress symptoms.

STUDY DESIGN

The study used a population-based cross-sectional design.

METHODS

Data from the BlackVax dataset on COVID-19 vaccination in Black individuals in Canada was analyzed (n = 2002, 51.66% women). Logistic regression analyses were performed to examine the association between MRD and independent variables.

RESULTS

32.55% of participants declared having experienced MRD in healthcare services. Participants with MRD were less vaccinated against COVID-19, presented higher scores of vaccine mistrust, conspiracy beliefs, COVID-19 related stressors, depression, anxiety, and stress, and had lower scores of community resilience. They were more likely to experience depression (AOR = 2.13, P < 0.001), anxiety (AOR = 2.00, P < 0.001), and stress symptoms (AOR = 2.15, P < 0.001). Participants who experienced MRD were more likely to be unvaccinated (AOR = 1.35, P = 0.009).

CONCLUSIONS

Racial discrimination experienced by Black individuals in health services is a major public health concern and threat to population health in Canada. Federal, provincial, and municipal public health agencies should adapt their programs, strategies, tools, and campaigns to address the mistrust created by racial discrimination.

Socio-demographic determinants of COVID-19 vaccine uptake in Ontario: Exploring differences across the Health Region model

The COVID-19 pandemic continues to be a worldwide public health concern. Although vaccines against this disease were rapidly developed, vaccination uptake has not been equal across all the segments of the population, particularly in the case of underrepresented groups. However, there are also differences in vaccination across geographical areas, which might be important to consider in the development of future public health vaccination policies. In this study, we examined the relationship between vaccination status (having received the first dose of a COVID-19 vaccine), socio-economic strata, and the Health Regions for individuals in Ontario, Canada. Our results show that between October of 2021 and January of 2022, individuals from underrepresented communities were three times less likely to be vaccinated than White/Caucasian individuals across the province of Ontario, and that in some cases, within these groups, individuals in low-income brackets had significantly higher odds of vaccination when compared to their peers in high income brackets. Finally, we identified significantly lower odds of vaccination in the Central, East and West Health Regions of Ontario within certain underrepresented groups. This study shows that there is an ongoing need to better understand and address differences in vaccination uptake across diverse segments of the population of Ontario that the pandemic has largely impacted.

COVID-19 among Black people in Canada: a scoping review

INTRODUCTION

The COVID-19 pandemic exacerbated health inequities worldwide. Research conducted in Canada shows that Black populations were disproportionately exposed to COVID-19 and more likely than other ethnoracial groups to be infected and hospitalized. This scoping review sought to map out the nature and extent of current research on COVID-19 among Black people in Canada.

METHODS

Following a five-stage methodological framework for conducting scoping reviews, studies exploring the effects of the COVID-19 pandemic on Black people in Canada, published up to May 2023, were retrieved through a systematic search of seven databases. Of 457 identified records, 124 duplicates and 279 additional records were excluded after title and abstract screening. Of the remaining 54 articles, 39 were excluded after full-text screening; 2 articles were manually picked from the reference lists of the included articles. In total, 17 articles were included in this review.

RESULTS

Our review found higher rates of COVID-19 infections and lower rates of COVID-19 screening and vaccine uptake among Black Canadians due to pre-COVID-19 experiences of institutional and structural racism, health inequities and a mistrust of health care professionals that further impeded access to health care. Misinformation about COVID-19 exacerbated mental health issues among Black Canadians.

CONCLUSIONS

Our findings suggest the need to address social inequities experienced by Black Canadians, particularly those related to unequal access to employment and health care. Collecting race-based data on COVID-19 could inform policy formulation to address racial discrimination in access to health care, quality housing and employment, resolve inequities and improve the health and well-being of Black people in Canada.

Intersecting Inequities in COVID-19 Vaccination: A Discourse Analysis of Information Use and Decision-Making Among Ethnically Diverse Parents in Canada

BACKGROUND

Little is known about how intersecting social privilege and disadvantage contribute to inequities in COVID-19 information use and vaccine access. This study explored how social inequities intersect to shape access to and use of COVID-19 information and vaccines among parents in Canada.

METHODS

We conducted semi-structured interviews on COVID-19 vaccination information use with ethnically diverse parents of children ages 11 to 18 years from April to August 2022. We purposefully invited parents from respondents to a national online survey to ensure representation across diverse intersecting social identities. Five researchers coded transcripts in NVivo using a discourse analysis approach informed by intersectionality. Our analysis focused on use of vaccine information and intersecting privileges and oppressions, including identifying with equity-denied group(s).

RESULTS

Interview participants (N = 48) identified as ethnically diverse non-Indigenous (n = 40) and Indigenous (n = 8) Peoples from seven Canadian provinces. Racialized minority or Indigenous participants reflected on historical and contemporary events of racism from government and medical institutions as barriers to trust and access to COVID-19 information, vaccines, and the Canadian healthcare system. Participants with privileged social locations showed greater comfort in resisting public health measures. Despite the urgency to receive COVID-19 vaccines, information gaps and transportation barriers delayed vaccination among some participants living with chronic medical conditions.

CONCLUSION

Historicization of colonialism and ongoing events of racism are a major barrier to trusting public health information. Fostering partnerships with trusted leaders and/or healthcare workers from racialized communities may help rebuild trust. Healthcare systems need to continuously implement strategies to restore trust with Indigenous and racialized populations.

The state of COVID-19 vaccine confidence and need in Black individuals in Canada: Understanding the role of sociodemographic factors, health literacy, conspiracy theories, traumatic stressors and racial discrimination

BACKGROUND

Black communities in Canada have been among the most affected by the COVID-19 pandemic, in terms of number of infections and deaths. They are also among those most hesitant about vaccination against COVID-19. However, while a few studies have documented the factors associated with COVID-19 vaccine hesitancy, those related to vaccine confidence remain unknown. To respond to this gap, this study aims to investigate factors associated to vaccine confidence in Black individuals in Canada.

METHODS

A total of 2002 participants (1034 women) aged 14 to 89 years old (Mean age = 29.34, SD = 10.13) completed questionnaires assessing sociodemographic information, COVID-19 vaccine confidence and need, health literacy, conspiracy beliefs, major racial discrimination, and traumatic stressors related to COVID-19.

RESULTS

Results showed an average score of COVID-19 vaccine confidence and need of 33.27 (SD = 7.24), with no significant difference between men (33.48; SD = 7.24) and women (33.08; SD = 7.91), t (1999) = 1.19, p = 0.234. However, there were significant differences according to employment status, migration status, age, inhabited province, spoken language, education, marital status, religion, and income. The linear regression model explained 25.8 % of the variance and showed that health literacy (B = 0.12, p < 0.001) and traumatic stressors related to COVID-19 (B = 0.21, p < .001) predicted COVID-19 vaccine confidence and need positively, while conspiracy beliefs (B = -1.14, p < 0.001) and major racial discrimination (B = -0.20, p = 0.044) predicted it negatively.

CONCLUSIONS

This study showed that building the confidence of Black communities in vaccines requires health education, elimination of racial discrimination in the Canadian society and a focus on certain groups (e.g., young people, those living in Quebec and Ontario). The results also argue in favor of involving community leaders and organizations in the development and implementation of vaccination-related tools, strategies and programs by city, provincial and federal public health agencies.

COVID-19 vaccine uptake, conspiracy theories, and health literacy among Black individuals in Canada: Racial discrimination, confidence in health, and COVID-19 stress as mediators

Factors influencing vaccine uptake in Black individuals remain insufficiently documented. Understanding the role of COVID-19 related stress, conspiracy theories, health literacy, racial discrimination experiences, and confidence in health authorities can inform programs to increase vaccination coverage. We sought to analyze these factors and vaccine uptake among Black individuals in Canada. A representative sample of 2002 Black individuals from Ontario, Quebec, Alberta, Nova Scotia, New Brunswick, British Columbia, and Manitoba, aged 14 years or older completed questionnaires assessing vaccine uptake, health literacy, conspiracy theories, racial discrimination experiences, COVID-19-related stress, and confidence in health authorities. Mediation analyses were conducted to assess (1) the effect of health literacy on COVID-19 vaccination uptake through confidence and need, COVID-19 related traumatic stress, and racial discrimination, and (2) the effect of conspiracy beliefs on COVID-19 vaccination uptake through the same factors. Overall, 69.57% (95% confidence interval, 67.55%-71.59%) of the participants were vaccinated and 83.48% of them received two or more doses. Those aged 55 years and older were less likely to be vaccinated, as well as those residing in British Columbia and Manitoba. Mediation models showed that the association between health literacy and COVID-19 vaccine uptake was mediated by confidence in health authorities (B = 0.02, p < 0.001), COVID-19-related stress (B = -0.02, p < 0.001), and racial discrimination (B = -0.01, p = 0.032), but both direct and total effects were nonsignificant. Lastly, conspiracy beliefs were found to have a partial mediation effect through the same mediators (B = 0.02, p < 0.001, B = -0.02, p < 0.001, B = -0.01, p = 0.011, respectively). These findings highlight the need for targeted interventions to address vaccine hesitancy and inform approaches to improve access to vaccinations among Black communities.

Examining vaccine hesitancy among a diverse sample of Canadian adults

The aim of this study was to explore the sociodemographic and individual-level factors associated with vaccine hesitancy in general, including political affiliation and beliefs in vaccine conspiracy theories, in a diverse group of Canadian adults within the context of the COVID-19 pandemic. 641 responses were included in the analysis, with those self-identifying as Indigenous, Black Canadian, and low-income (household income <$40,000) being sampled to yield data from historically marginalized populations. Demographic variables and responses to questions on vaccine hesitancy, and beliefs in vaccine conspiracy theories were used to explore explanatory variables of vaccine hesitancy. General linear regression models were fit using the method of least squares via PROC GLM and used to examine sociodemographic and individual explanatory variables of vaccine hesitancy. Age, ethnicity, political affiliation, and beliefs in vaccine conspiracies were associated with vaccine hesitancy. Findings are discussed in relation to the critical role of distrust and misinformation in hesitancy. Our data provide insight into how Canadian provincial governments may promote uptake of vaccines in ways that target diverse groups that may differ from those developed in a pre-pandemic context.

Incidence, Racial Disparities and Factors Related to Psychosis among Black Individuals in Canada: A Scoping Review

OBJECTIVE

Black communities are increasingly concerned about psychosis, a worry echoed by provincial health-care systems across Canada. Responding to the lack of evidence on psychosis in Black communities, this scoping review examined the incidence and prevalence of psychosis, access to care (pathways to care, coercive referrals, interventions, etc.), treatments received, and stigma faced by individuals with psychosis.

METHOD

To identify studies, a comprehensive search strategy was developed and executed in December 2021 across 10 databases, including APA PsycInfo, CINAHL, MEDLINE and Web of Science. Subject headings and keywords relating to Black communities, psychosis, health inequalities, Canada and its provinces and territories were used and combined. The scoping review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping review (PRISMA-ScR) reporting standard.

RESULTS

A total of 15 studies met the inclusion criteria, all of them conducted in Ontario and Quebec. Results highlight different disparities in psychosis among Black communities. Compared to other Canadian ethnic groups, Black individuals are more likely to be diagnosed with psychosis. Black individuals with psychosis are more likely to have their first contact with health-care settings through emergency departments, to be referred by police and ambulance services, and to experience coercive referrals and interventions, and involuntary admission. Black individuals experience a lower quality of care and are the ethnic group most likely to disengage from treatment.

CONCLUSION

This scoping review reveals many gaps in research, prevention, promotion and intervention on psychosis in Black individuals in Canada. Future studies should explore factors related to age, gender, social and economic factors, interpersonal, institutional and systemic racism, and psychosis-related stigma. Efforts should be directed toward developing trainings for health-care professionals and promotion and prevention programs within Black communities. Culturally adapted interventions, racially disaggregated data, and increased research funding are needed.

Factors Associated with the Usefulness of Public Health Communication in the Context of COVID-19: Lessons Learned from the African, Caribbean, and Black Communities in Ottawa, Ontario

Public health communication is critical for promoting behaviours that can prevent the transmission of COVID-19. However, there are concerns about the effectiveness of public health communication within Canada's African, Caribbean, and Black (ACB) communities. In the community sample of ACB people in Ottawa, Ontario, we asked community members if they perceive public health message related to COVID-19 to be effective. Using this question, the current study aimed to explore factors associated with the perceived usefulness of public health messages related to COVID-19. Results from the multivariate analysis have shown that ACB people with lower levels of risk perception for COVID-19 were less likely to perceive that public health messages were useful (OR = 0.405, p < 0.01). In addition, mistrust in government COVID-19 information was also negatively associated with their perception that health messages are useful (OR = 0.169, p < 0.01). For socioeconomic status, ACB people with no high school diploma (OR = 0.362, p < 0.05) and income dissatisfaction (OR = 0.431, p < 0.05) were less likely to report the perceived usefulness compared to those with a bachelor's degree and income satisfaction. Based on these findings, we discussed implications for policymakers and directions for future research.

Prevalence and determinants of depression, anxiety, and stress symptoms among Black individuals in Canada in the context of the COVID-19 pandemic

The COVID-19 pandemic has disproportionately affected Black communities in Canada in terms of infection, hospitalizations, and mortality rates. It exacerbated social, economic, and health disparities that can impact their mental health. We investigated the prevalence and predictors of symptoms of depression, anxiety, and stress in Black individuals in Canada. A community-representative weighted sample of 2002 Black individuals (51.66% women) aged 14 to 94 years old (Mean age 29.34; SD = 10.13). Overall, 40.94%, 44.50%, and 31.36% of participants were classified as having clinically meaningful anxiety, depression, and stress levels, respectively, based on DASS scores. Men (45.92%) reported a higher prevalence of anxiety than women (36.27%), χ² (1) = 19.24, p<.001, but similar symptoms of depression and stress. The progression of the prevalence of anxiety, depression, and stress symptoms were consistent with the progression of the prevalence of everyday racial discrimination. After controlling for socio-demographic variables, regression models showed that everyday discrimination (B = 0.14, p=.001, B = 0.14, p= .006, B = 0.18, p< .001), major experiences of racial discrimination (B = 0.30, p=.046, B = 0.34, p= .033, B = 0.35, p=.024), and COVID-19 traumatic stressors (B = 0.43, p<.001, B = 0.43, p< .001, B = 0.44, p< .001) were positively associated with anxiety, while community resilience (B= -0.02, p= .039, B= -0.04, p= .001, B= -0.03, p= .014) was negatively associated with anxiety, depression, and stress, respectively. This study demonstrates the need to address racial discrimination in implementing prevention and intervention programs among Black individuals and to consider intersectional factors related to age, birthplace, language spoken, and province of residence.

Vaccine mistrust among Black individuals in Canada: The major role of health literacy, conspiracy theories, and racial discrimination in the healthcare system

The COVID-19 pandemic disproportionately affected Black communities in Canada in terms of infection and mortality rates compared to the general population. Despite these facts, Black communities are among those with the highest level of COVID-19 vaccine mistrust (COVID-19 VM). We collected novel data to analyze the sociodemographic characteristics and factors associated with COVID-19 VM among Black communities in Canada. A survey was conducted among a representative sample of 2002 Black individuals (51.66% women) aged 14-94 years (M = 29.34; SD = 10.13) across Canada. Vaccine mistrust was assessed as the dependent variable and conspiracy theories, health literacy, major racial discrimination in healthcare settings, and sociodemographic characteristics of participants were assessed as independent variables. Those with a history of COVID-19 infection had higher COVID-19 VM score (M = 11.92, SD = 3.88) compared to those with no history of infection (M = 11.25, SD = 3.83), t (1999) = -3.85, p < 0.001. Participants who reported having experienced major racial discrimination in healthcare settings were more likely to report COVID-19 VM (M = 11.92, SD = 4.03) than those who were not (M = 11.36, SD = 3.77), t (1999) = -3.05, p = 0.002. Results also showed significant differences for age, education level, income, marital status, provinces, language, employment status, and religion. The final hierarchical linear regression showed that conspiracy beliefs (B = 0.69, p < 0.001) were positively associated with COVID-19 VM, while health literacy (B = -0.05, p = 0.002) was negatively associated with it. The mediated moderation model showed that conspiracy theories completely mediated the association between racial discrimination and vaccine mistrust (B = 1.71, p < 0.001). This association was also completely moderated by the interaction between racial discrimination and health literacy (B = 0.42, p = 0.008), indicating that despite having a high level of health literacy, those who experienced major racial discrimination in health services developed vaccine mistrust. This first study on COVID-19 VM exclusively among Black individuals in Canada provides data that can significantly impact the development of tools, trainings, strategies, and programs to make the health systems free of racism and increase their confidence in vaccination for COVID-19 and other infectious diseases.

Incidence, factors, and disparities related to cancer among Black individuals in Canada: A scoping review

BACKGROUND

In Canada, two of five individuals will be diagnosed with cancer in their lifetime and one in four will die from this disease. Given the disparities observed in health research among Black individuals, we conducted a scoping review to analyze the state of cancer research in Canadian Black communities regarding prevalence, incidence, screening, mortality, and related factors to observe advances and identify gaps and disparities.

METHODS

A comprehensive search strategy was developed and executed in December 2021 across 10 databases (e.g., Embase). Of 3451 studies generated by the search, 19 were retained for extraction and included in this study.

RESULTS

Studies were focused on a variety of cancer types among Black individuals including anal, breast, cervical, colorectal, gastric, lung, and prostate cancers. They included data on incidence, stage of cancer at diagnosis, type of care received, diagnostic interval length, and screening. A few studies also demonstrated racial disparities among Black individuals. This research reveals disparities in screening, incidence, and quality of care among Black individuals in Canada.

CONCLUSIONS

Given the gaps observed in cancer studies among Black individuals, federal and provincial governments and universities should consider creating special funds to generate research on this important health issue.

PLAIN LANGUAGE SUMMARY

Important gaps were observed on research on cancer among Black communities in Canada. Studies included in the scoping review highlights disparities in screening, incidence, and quality of care among Black individuals in Canada.

Megastudies: A New Approach to Reducing Vaccine Hesitation Worldwide

Vaccine hesitancy is a considerable obstacle to achieving vaccine protection worldwide. There needs to be more evidence-based research for interventions for vaccine hesitancy. Existing effectiveness evaluations are limited to one particular hypothesis, and no studies have compared the effectiveness of different interventions. A megastudy takes a large-scale, multi-intervention, uniform participant and the same evaluation criteria approach to evaluate many interventions simultaneously and find the most effective ones. Therefore, megastudies can help us find the most effective interventions for vaccine hesitancy. Additionally, considering the complex causes of vaccine hesitancy, we design interventions that involve social factors in megastudies. Lastly, quality control and justice are critical issues for megastudies in the future.
