Objectives of the present study were to 1) examine accuracy of COVID-19 public health restriction knowledge and the impact of information source, 2) assess the effect of perceived level of restriction on perceived infection risk of COVID-19 infection and level of compliance with restrictions, and 3) investigate the relationship between mental health outcomes and perceived as well as actual level of restriction. Canadians (n = 5,051) completed an online survey between December 2020 and March 2021 assessing public health restriction knowledge, accuracy of this knowledge, information sources about COVID-19, perceived infection risk, compliance with restrictions, loneliness, anxiety, and depressive symptoms. Approximately half of our sample had accurate knowledge of the restrictions in their region/province, which significantly differed by province. Individuals who perceived restriction levels to be higher than they were, reported significantly greater perceived infection risk, more compliance with restrictions, worse mental health, and greater loneliness. Individuals living under moderate restrictions had better mental health and experienced less loneliness compared to minor, significant and extreme restriction levels. Findings suggest that while restrictions are beneficial for compliance, stronger and clearer restrictions should be coupled with mental health supports to remediate the negative effects of restrictions and uncertainty on mental health and loneliness., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2024.

Objective: The aim of the study is to describe mental health impacts of the COVID-19 pandemic and identify roles that predict distress among Canadian healthcare workers (HCWs)., Methods: Using data from three cross-sectional Canadian surveys, we compared 799 HCWs to demographically matched controls and compared HCWs with and without COVID-19 patient contact. Participants completed validated measures of depression, anxiety, trauma-related stress, alcohol problems, coping self-efficacy, and sleep quality., Results: Non-HCWs reported more depression and anxiety in Fall 2020 and more alcohol problems in Fall/Winter 2021 than HCWs. In Winter 2020-2021, HCWs reported more trauma-related stress than non-HCWs. As of early 2021, HCWs with direct patient contact reported worse symptoms across nearly all measures than HCWs without., Conclusions: Although Canadian HCWs did not report worse mental health than demographically similar peers, mental health supports are needed for HCWs providing direct patient care., Competing Interests: Conflict of interest: T.P. also received funding from the Canadian Foundation for Innovation, the Weston Foundation, and NDRIO-Portage.

Background: Many blood operators around the world face the challenge of increasing the number of donors of African ancestry to meet the transfusion needs of people living with sickle cell disease. This article reports results of the barriers to blood donation for young adults (aged 19-35) in Canada who identify as African, Caribbean, or Black., Study Design and Methods: A community-based qualitative study was conducted by researchers from community organizations, blood operator, and universities. In-depth focus groups and interviews (n = 23) were conducted from Dec 2021 to Apr 2022 and thematic analysis was completed., Results: Applying a socio-ecological model, multiple levels of interacting barriers to blood donation were identified. These included macro-level barriers (e.g., systemic racism, mistrust of the healthcare system, sociocultural beliefs and views about blood and sickle cell disease), mezzo-level barriers (e.g., deferral criteria, minimum hemoglobin levels, donor questionnaire, access, parental concerns), and microlevel barriers (e.g., limited knowledge of blood needs for people with sickle cell disease, lacking information about blood donation process, fear of needles, personal health concerns)., Discussion: This study is the first to focus on barriers to donation for African, Caribbean, and Black young adults across Canada. Parental concerns, informed by parents' experiences of inequitable healthcare and mistrust, emerged as a novel finding in our study population. Results suggest that higher order (macro-level) barriers influence and may reinforce lower order (mezzo- and microlevel) barriers. As such, interventions aimed at addressing barriers to donation should keep in view all levels with particular attention paid to higher order barriers., (© 2023 The Authors.

Background: The COVID-19 pandemic's mental health impact is well-established. While early evidence suggested suicide deaths remained stable or declined, suicidal ideation (SI) became more prevalent than before the pandemic. Our study: (1) examined the prevalence and distribution of SI among Canadian adults, (2) compared SI among those with and without pre-existing mental illnesses, and (3) evaluated associations between pandemic-related stressors (i.e., unemployment, insecure employment, loss of income, medical vulnerability, COVID-19 exposure) with SI, and whether such associations were mediated by depression, thwarted belongingness, perceived burdensomeness, or perceived discrimination., Methods: The sample was comprised of data gathered at three timepoints (Wave 1 08/18/2020-10/01/2020, n = 6629; Wave 2 12/21/2020-03/31/2021, n = 5920; Wave 3 09/07/2021-12/07/2021, n = 7354). Quota-based responses from survey research panels which matched the geographic, age, and sex distribution of the Canadian population were supplemented with convenience-sampled responses., Results: The prevalence of SI was 4.1 % (Wave 1), 5.3 % (Wave 2), and 5.8 % (Wave 3). Odds of SI were higher for respondents under the age of 35 years and with pre-existing mental illnesses. SI was associated with quarantining due to suspected or confirmed COVID-19 exposure, potential COVID-19 exposure at work, medical vulnerability toward COVID-19, insecure employment or unemployment, and income loss. These associations were mediated by psychological experiences, particularly depression and thwarted belongingness., Limitations: This cross-sectional, observational study cannot establish temporality or causality., Conclusion: Results highlight groups who may benefit from enhanced screening for depression and suicide risk. Reducing depression and increasing sense of belonging should be prioritized., Competing Interests: Conflict of interest The authors have no conflicts of interest to declare., (Copyright © 2023 The Authors.
