Social inequalities in COVID-19 mortality by area and individual-level characteristics in Canada, January to July/August 2020: Results from two national data integrations.

Background: Despite early reports of social determinants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (COVID-19) burden, national Canadian reporting on COVID-19 inequalities has been limited. The objective of this study is to describe inequalities in COVID-19 mortality in Canada using preliminary data, as part of the Pan-Canadian Health Inequalities Reporting Initiative. Methods: Two provisional Canadian Vital Statistics Death Database integrations were used. Data concerning deaths between January 1 and July 4, 2020, among private-dwelling residents were linked to individual-level data from the 2016 short-form Census, and disaggregated by sex and low-income status, dwelling type, household type and size. Data concerning deaths between January 1 and August 31, 2020 linked to 2016 Census area data were disaggregated by sex and neighbourhood ethno-cultural composition quintiles (based on the proportion of residents who are recent immigrants, visible minorities, born outside of Canada, with no knowledge of English or French), income quintiles and urban residence. The COVID-19 age-standardized mortality rate (per 100,000 population) differences and ratios between groups were estimated. Results: As of July/August 2020, apartment dwellers, residents of urban centres, neighbourhoods with the highest ethno-cultural composition or lowest income experienced 14 to 30 more COVID-19-related deaths/100,000 compared with reference groups (residents of single-detached homes, outside of urban centres, with lowest ethno-cultural concentration or highest income, respectively). Per 100,000 population, sex/gender inequalities were also larger in these four groups (11 to 18 more male than female deaths) than in the reference groups (two to four more male than female deaths). Conclusion: These findings highlight how populations facing socioeconomic disadvantage have experienced a higher overall burden of deaths. Areas for future research are discussed to guide health equity-informed pandemic response.

Is childhood migration a mental health risk? Exploring health behaviors and psychosocial resources as pathways using the cross-sectional Canadian Community Health Survey.

Drawing on the Stress Process Model, this study investigates the effect of early migration on health behaviors and psychosocial resources. Further, I consider whether health behaviors and psychosocial processes lead to higher psychological distress for childhood immigrants in adulthood. Cross-sectional data from the Canadian Community Health Survey-Mental Health 2012 (N = 4282) reveal that compared to adult immigrants, childhood immigrants are not only four times more likely to use drugs, but also experience greater interpersonal strain. However, health behaviors such as these contribute less to psychological distress than do psychosocial resources. Additionally, longer duration of migration is found to reduce psychological distress when controlling for age at migration, thus suggesting the migrant health literature should examine age-salient life challenges at the time of migration, instead of continuing to use duration of migration as a proxy for negative acculturation.
