Morbidity among resettled refugees at arrival in Ontario, Canada (1994-2017): a controlled interrupted time series study examining the effect of the Immigration Refugee Protection Act, 2002.

Background: Immigration inadmissibility on medical grounds is common among high-income countries. In Canada, the Immigrant and Refugee Protection Act (IRPA) became law in 2002. With humanitarian protection as a priority, IRPA removed medical inadmissibility based on exceeding a cost threshold for the projected use of health and social services for resettled refugees.

Discrimination and Racial Inequities in Self-reported Mental Health Among Immigrants and Canadian-Born Individuals in a Large, Nationally Representative Canadian Survey.

We examined the link between discrimination and self-rated mental health (SRMH) among immigrants and Canadian-born individuals, stratified according to an individual's identification as racialized or white. Using data from Canada's General Social Survey (2014) (weighted N = 27,575,000) with a novel oversample of immigrants, we estimated the association of perceived discrimination with SRMH separately among immigrants and Canadian-born individuals and stratified by racialized status. Among immigrants, we also investigated whether age-at-arrival attenuated or strengthened associations.

Reported community engagement in health equity research published in high-impact medical journals: a scoping review.

Objective: To assess reported community engagement in the design and conduct of health equity-focused articles published in high-impact journals.

Design: Scoping review follows guidance from the Joanna Briggs Institute and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist.

Data Sources: We selected the three highest-ranked journals from the 'Medicine-General and Internal' category including the Journal of the American Medical Association (JAMA), The Lancet and The New England Journal of Medicine (NEJM) along with all journals under their family of subspecialty journals (JAMA Network, The Lancet Group and the NEJM Group).

COVID-19 hospitalization, mortality and pre-mature mortality by a history of immigration in Ontario, Canada: a population-based cohort study.

Background: Immigrants in high-income countries experienced inequities in COVID-19 severe outcomes. We examined hospitalization and death throughout the pandemic, and change during the vaccine era, in Ontario, Canada.

Methods: We conducted a population-based study using linked immigration and health data, following two cohorts for 20 months from January 1, 2020 (pre-vaccine) and September 1, 2021 (vaccine era).

Asian-White disparities in obstetric anal sphincter injury: a systematic review and meta-analysis.

Objective: Obstetrical anal sphincter injury describes a severe injury to the perineum and perianal muscles after birth. Obstetrical anal sphincter injury occurs in approximately 4.4% of vaginal births in the United States; however, racial and ethnic inequities in the incidence of obstetrical anal sphincter injury have been shown in several high-income countries.

COVID-19 vaccine equity: a retrospective population-based cohort study examining primary series and first booster coverage among persons with a history of immigration and other residents of Ontario, Canada.

Introduction: Immigrants were disproportionately impacted by COVID-19 and experience unique vaccination barriers. In Canada (37 million people), 23% of the population is foreign-born. Immigrants constitute 60% of the country's racialized (non-white) population and over half of immigrants reside in Ontario, the country's most populous province.

Asian-white disparities in obstetric anal sphincter injury: Protocol for a systematic review and meta-analysis.

Background: Obstetric anal sphincter injury (OASI) describes severe injury to the perineum and perineum and perianal muscles following birth and occurs in 4.4% to 6.0% of vaginal births in Canada.

Gender-based discrimination and son preference in Punjabi-Canadian families: a community-based participatory qualitative research study.

Objectives: To conduct a qualitative study, guided by the principles of community-based participatory research, with the following objectives: (1) to provide a conceptual framework describing the drivers of son preference; (2) to understand experiences of son preference among Punjabi-Canadians and (3) with this understanding, identify and co-design an appropriate educational tool.

Design, Setting, Participants, Methods: Qualitative study consisting of four bilingual (Punjabi and English) focus group discussions with 11 mothers, 4 fathers and 17 grandmothers in Toronto and Brampton, Canada. Participants were queried about experiences and perspectives related to reproductive decision-making, gender equity and son preference, and for appropriate approaches to reducing inequities.

Primary health care utilization in the first year after arrival by refugee sponsorship model in Ontario, Canada: A population-based cohort study.

Background: Canada's approach to refugee resettlement includes government sponsorship, a pioneering private sponsorship model and a third blended approach. Refugees are selected and supported differently in each approach including healthcare navigation. Little is known about how well private sponsors facilitate primary care navigation and whether this changed during the large-scale 2015 Syrian resettlement initiative characterized by civic and healthcare systems engagement.

COVID-19 Vaccine Uptake in Immigrant, Refugee, and Nonimmigrant Children and Adolescents in Ontario, Canada.

Importance: COVID-19 vaccinations are recommended for minors. Surveys indicate lower vaccine acceptance by some immigrant and refugee groups.

Objective: To identify characteristics in immigrant, refugee, and nonimmigrant minors associated with vaccination.

SARS-CoV-2 testing and COVID-19-related primary care use among people with citizenship, permanent residency, and temporary immigration status: an analysis of population-based administrative data in British Columbia.

Objectives: Having temporary immigration status affords limited rights, workplace protections, and access to services. There is not yet research data on impacts of the COVID-19 pandemic for people with temporary immigration status in Canada.

Methods: We use linked administrative data to describe SARS-CoV-2 testing, positive tests, and COVID-19 primary care service use in British Columbia from January 1, 2020 to July 31, 2021, stratified by immigration status (citizen, permanent resident, temporary resident).

Health Care Use and System Costs Among Pediatric Refugees in Canada.

Background: Resettled refugees land in Canada through 3 sponsorship models with similar health insurance and financial supports but differences in how resettlement is facilitated. We examined whether health system utilization, costs, and aggregate 1-year morbidity differed by resettlement model.

Methods: Population-based matched cohort study in Ontario, 2008 to 2018, including pediatric (0-17 years) resettled refugees and matched Ontario-born peers and categorized refugees by resettlement model: (1) private sponsorship (PSRs), (2) Blended Visa Office-Referred program (BVORs), and (3) government-assisted refugee (GAR).

Multimorbidity and use of reversible contraception: Results from a Canadian cross-sectional survey.

Objective: Despite the importance of contraception for pregnancy planning in females with chronic conditions, little is known about contraception use in those with two or more chronic conditions-i.e., multimorbidity.

Linking national immigration data to provincial repositories: The case of Canada.

Background: Canadian health data repositories link datasets at the provincial level, based on their residents' registrations to provincial health insurance plans. Linking national datasets with provincial health care registries poses several challenges that may result in misclassification and impact the estimation of linkage rates. A recent linkage of a federal immigration database in the province of Manitoba illustrates these challenges.

The social determinants of health as predictors of adherence to public health preventive measures among parents and young children during the COVID-19 pandemic: a longitudinal cohort study.

Objectives: To investigate whether social determinants of health (SDOH) are predictive of adherence to public health preventive measures and to describe changes in adherence over time among parents and children.

Methods: A longitudinal study was conducted in children aged 0-10 years and their parents through the TARGet Kids! COVID-19 Study in the Greater Toronto Area, Canada (April-July 2020). This study included 335 parents (2108 observations) and 416 children (2632 observations).

COVID-19 Economic Response and Recovery: A Rapid Scoping Review.

This rapid scoping review of existing evidence and research gaps addressed the following question: what research evidence exists and what are the research gaps at global, regional, and national levels on interventions to protect jobs, small- and medium-sized enterprises, and formal/informal sector workers in socioeconomic response to the coronavirus disease 2019 (COVID-19) pandemic? The results are based on 79 publications deemed eligible for inclusion after the screening and prioritizing of 1,658 records. The findings are organized according to the 3 main categories of socioeconomic interventions-protecting jobs, enterprises, and workers-although the 3 are intertwined. Most results were derived from global-level gray literature with recommendations for interventions and implicit links to the sustainable development goals.

Association Between Chronic Medical Conditions and Acute Perinatal Psychiatric Health-Care Encounters Among Migrants: A Population-Based Cohort Study.

Objectives: To examine the relationship between prepregnancy chronic medical conditions (CMCs) and the risk of acute perinatal psychiatric health-care encounters (i.e., psychiatric emergency department visits, hospitalizations) among refugees, nonrefugee immigrants, and long-term residents in Ontario.

Induced abortion according to immigrants' birthplace: a population-based cohort study.

Background: Most abortions occur due to unintended pregnancy. Unintended pregnancies are linked to poor health outcomes. Canada receives immigrants from countries with disparate sexual and reproductive health contexts which may influence abortion rates post-migration.

Refugee mothers, migration pathways and HIV: a population-based cohort study.

Forced migration and extended time spent migrating may lead to prolonged marginalization and increased risk of HIV. We conducted a population-based cohort study to examine whether secondary migration status, where secondary migrants resided in a transition country prior to arrival in Ontario, Canada and primary migrants arrived directly from their country of birth, modified the relationship between refugee status and HIV. Unadjusted and adjusted prevalence ratios (APR) and 95% confidence intervals (CI) were estimated using log-binomial regression.

Health outcomes related to the provision of free, tangible goods: A systematic review.

Background: Free provision of tangible goods that may improve health is one approach to addressing discrepancies in health outcomes related to income, yet it is unclear whether providing goods for free improves health. We systematically reviewed the literature that reported the association between the free provision of tangible goods and health outcomes.

Methods: A search was performed for relevant literature in all languages from 1995-May 2017.

Postdiagnosis Isoflavone and Lignan Intake in Newly Diagnosed Breast Cancer Patients: Cross-Sectional Survey Shows Considerable Intake from Previously Unassessed High-Lignan Foods.

Background: Isoflavones and lignans (phytoestrogens) are dietary components with potential anticarcinogenic effects. Although the intake of isoflavones and lignans may affect breast cancer treatment and prognosis-and associations may differ by menopausal status-postdiagnosis intake data are limited.

Objective: We aimed to describe postdiagnosis isoflavone and lignan intake in newly diagnosed breast cancer patients, examine differences by menopausal status and phytoestrogen type, and inform the assessment of diet and survival in future prognostic studies.

Sex ratios at birth among second-generation mothers of South Asian ethnicity in Ontario, Canada: a retrospective population-based cohort study.

Background: Son-biased sex ratios at birth (M:F), an extreme manifestation of son preference, are predominately found in East and South Asia. Studies have examined sex ratios among first-generation migrants from these regions, but few have examined second-generation descendants. Our objective was to determine whether son-biased sex ratios persist among second-generation mothers with South Asian ethnicity in Ontario, Canada.

Interventions to reduce adverse health outcomes resulting from manifestations of gender bias amongst immigrant populations: a scoping review.

Background: Immigrants to Western countries increasingly originate from countries with pervasive gender inequalities, where women experience disproportionately high rates of threats to their well-being. Health and social services in countries of settlement encounter several adverse outcomes linked to gender bias among immigrant groups. Little is known about interventions implemented to address manifestations of gender bias among immigrant populations.

Refugee maternal and perinatal health in Ontario, Canada: a retrospective population-based study.

Objectives: Immigrants are thought to be healthier than their native-born counterparts, but less is known about the health of refugees or forced migrants. Previous studies often equate refugee status with immigration status or country of birth (COB) and none have compared refugee to non-refugee immigrants from the same COB. Herein, we examined whether: (1) a refugee mother experiences greater odds of adverse maternal and perinatal health outcomes compared with a similar non-refugee mother from the same COB and (2) refugee and non-refugee immigrants differ from Canadian-born mothers for maternal and perinatal outcomes.
