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). Ovid MEDLINE was searched between 1 January 2021 to 22 September 2022. ELIGIBILITY CRITERIA: We included health equity-focused articles and assessed for the reporting of community engagement at each stage of the research process. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted data from articles that met the inclusionary criteria. Inter-rater reliability was assessed using Cohen's kappa to measure the agreement between two independent reviewers. Disagreements were adjudicated by a third independent reviewer. RESULTS: 7616 articles were screened, 626 (8.2%) met our inclusion criteria: 457 (3.8%) were published by the JAMA Network; 167 (2.4%) by The Lancet Group; and 2 (0.2%) by the NEJM group. Most articles were from USA (68.4%) and focused on adult populations (57.7%). The majority of the articles focused on the topic of race/ethnicity (n=176, 28.1%), socioeconomic status (n=114, 18.2%) or multiple equity topics (n=111, 17.7%). The use of community engagement approaches was reported in 97 (15.5%) articles, of which 13 articles (13.4%) reported engagement at all stages. The most common form of reported engagement was in the acknowledgement or additional contribution section (n=86, 88.7%). CONCLUSIONS: Community engagement is infrequently reported in health equity-focused research published in high-impact medical journals.

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. The prevalence of discrimination was higher among racialized compared to white immigrants (18.9% versus 11.8%), and among racialized compared to white non-immigrants (20.0% versus 10.5%). In the adjusted model with immigrants, where white immigrants not reporting discrimination were the referent group, both white (adjusted prevalence odds ratio [aPOR] 6.11, 95% confidence interval [CI] 3.08, 12.12) and racialized immigrants (aPOR 2.28, 95% CI 1.29, 4.04) who experienced discrimination reported poorer SRMH. The associations were weaker among immigrants who immigrated in adulthood. In the adjusted model with non-immigrants, compared to unexposed white respondents, Canadian-born white respondents who experienced discrimination reported poorer SRMH (aPOR 3.62, 95% CI 2.99, 4.40) while no statistically significant association was detected among racialized respondents (aPOR 2.24, 95% CI 0.90, 5.58). Racialized respondents experienced significant levels of discrimination compared to white respondents irrespective of immigrant status. Discrimination was associated with poor SRMH among all immigrants, with some evidence of a stronger association for white immigrants and immigrants who migrated at a younger age. For Canadian-born individuals, discrimination was associated with poor SRMH among white respondents only.

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). We used multivariable Poisson generalized estimating equation regression to estimate adjusted rate ratios (aRR) with 95% confidence intervals (CI), accounting for age, sex and co-morbidities. We calculated age-standardized years of life lost (ASYRs) rates by immigrant category. Findings: Of 11,692,387 community-dwelling adults in the pre-vaccine era cohort and 11,878,304 community-dwelling adults in the vaccine era cohort, 21.6% and 21.4% of adults in each era respectively were immigrants. Females accounted for 57.9% and 57.8% of sponsored family, and 68.4% and 67.6% of economic caregivers, in each era respectively. Compared to other Ontarians in the pre-vaccine era cohort, hospitalization rates were highest for refugees (aRR [95% CI] 3.41 [3.39-3.44]) and caregivers (3.13 [3.07-3.18]), followed by sponsored family and other economic immigrants. Compared to other Ontarians, aRRs were highest for immigrants from Central America (5.00 [4.92-5.09]), parts of South Asia (3.95 [3.89-4.01]) and Jamaica (3.56 [3.51-3.61]) with East Asians having lower aRRs. Mortality aRRs were similar to hospitalization aRRs. In the vaccine era, all aRRs were attenuated and most were similar to or lower than other Ontarians, with refugees and a few regions maintaining higher rates. In the pre-vaccine era ASYRs were higher for all immigrant groups. ASYRs dropped in the vaccine era with only refugees continuing to have higher rates. Interpretation: Immigrants, particularly refugees, experienced greater premature mortality. aRRs for most immigrant groups dropped substantially after high vaccine coverage was achieved. Vaccine outreach and improvements in the social determinants of health are needed. Funding: Canadian Institutes of Health Research, Canada Research Chairs Program.

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. Specifically, an increased risk of obstetrical anal sphincter injury in individuals who identify as Asian vs those who identify as White has been documented among residents of the United States, Australia, Canada, Western Europe, and the Scandinavian countries. The high rates of obstetrical anal sphincter injury among the Asian diaspora in these countries are higher than obstetrical anal sphincter injury rates reported among Asian populations residing in Asia. A systematic review and meta-analysis of studies in high-income, non-Asian countries was conducted to further evaluate this relationship. DATA SOURCES: MEDLINE, Ovid, Embase, EmCare, and the Cochrane databases were searched from inception to March 2023 for original research studies. STUDY ELIGIBILITY CRITERIA: Observational studies using keywords and controlled vocabulary terms related to race, ethnicity and obstetrical anal sphincter injury. All observational studies, including cross-sectional, case-control, and cohort were included. 2 reviewers followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Meta-analysis of Observational Studies in Epidemiology recommendations. METHODS: Meta-analysis was performed using RevMan (version 5.4; Cochrane Collaboration, London, United Kingdom) for dichotomous data using the random effects model and the odds ratios as effect measures with 95% confidence intervals. Subgroup analysis was performed among Asian subgroups. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal tools. Meta-regression was used to determine sources of between-study heterogeneity. Results: A total of 27 studies conducted in 7 countries met the inclusion criteria encompassing 2,337,803 individuals. The pooled incidence of obstetrical anal sphincter injury was higher among Asian individuals than White individuals (pooled odds ratio, 1.64; 95% confidence interval, 1.48-1.80). Subgroup analyses showed that obstetrical anal sphincter injury rates were highest among South Asians and among population-based vs hospital-based studies. Meta-regression showed that moderate heterogeneity remained even after accounting for differences in studies by types of Asian subgroups included, study year, mode of delivery included, and study setting. Conclusion: Obstetrical anal sphincter injury is more frequent among Asian versus white birthing individuals in multiple high-income, non-Asian countries. Qualitative and quantitative research to elucidate underlying causal mechanisms responsible for this relationship are warranted.

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. Studies from high-income countries have identified an increased risk of OASI in individuals who identify as Asian race versus those who identify as white. This protocol outlines a systematic review and meta-analysis which aims to determine the incidence of OASI in individuals living in high-income countries who identify as Asian versus those of white race/ethnicity. We hypothesize that the pooled incidence of OASI will be higher in Asian versus white birthing individuals. METHODS: We will search MEDLINE, OVID, Embase, Emcare and Cochrane databases from inception to 2022 for observational studies using keywords and controlled vocabulary terms related to race, ethnicity and OASI. Two reviewers will follow the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines and Meta-analysis of Observational Studies (MOOSE) recommendations. Meta-analysis will be performed using RevMan for dichotomous data using the random effects model and the odds ratio (OR) as effect measure with a 95% confidence interval (CI). Subgroup analysis will be performed based on Asian subgroups (e.g., South Asian, Filipino, Chinese, Japanese individuals). Study quality assessment will be performed using The Joanna Briggs Institute Critical Appraisal tools. DISCUSSION: The systematic review and meta-analysis that this protocol outlines will synthesize the extant literature to better estimate the rates of OASI in Asian and white populations in non-Asian, high-income settings and the relative risk of OASI between these two groups. This systematic summary of the evidence will inform the discrepancy in health outcomes experienced by Asian and white birthing individuals. If these findings suggest a disproportionate burden among Asians, they will be used to advocate for future studies to explore the causal mechanisms underlying this relationship, such as differential care provision, barriers to accessing care, and social and institutional racism. Ultimately, the findings of this review can be used to frame obstetric care guidelines and inform healthcare practices to ensure care that is equitable and accessible to diverse populations.

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. Ontario had several strategies aimed at improving vaccine equity including geographic targeting of vaccine supply and clinics, as well as numerous community-led efforts. Our objectives were to (1) compare primary series vaccine coverage after it was widely available, and first booster coverage 6 months after its availability, between immigrants and other Ontario residents and (2) identify subgroups experiencing low coverage. Materials and methods: Using linked immigration and health administrative data, we conducted a retrospective population-based cohort study including all community-dwelling adults in Ontario, Canada as of January 1, 2021. We compared primary series (two-dose) vaccine coverage by September 2021, and first booster (three-dose) coverage by March 2022 among immigrants and other Ontarians, and across sociodemographic and immigration characteristics. We used multivariable log-binomial regression to estimate adjusted risk ratios (aRR). Results: Of 11,844,221 adults, 22% were immigrants. By September 2021, 72.6% of immigrants received two doses (vs. 76.4%, other Ontarians) and by March 2022 46.1% received three doses (vs. 58.2%). Across characteristics, two-dose coverage was similar or slightly lower, while three-dose coverage was much lower, among immigrants compared to other Ontarians. Across neighborhood SARS-CoV-2 risk deciles, differences in two-dose coverage were smaller in higher risk deciles and larger in the lower risk deciles; with larger differences across all deciles for three-dose coverage. Compared to other Ontarians, immigrants from Central Africa had the lowest two-dose (aRR = 0.60 [95% CI 0.58-0.61]) and three-dose coverage (aRR = 0.36 [95% CI 0.34-0.37]) followed by Eastern Europeans and Caribbeans, while Southeast Asians were more likely to receive both doses. Compared to economic immigrants, resettled refugees and successful asylum-claimants had the lowest three-dose coverage (aRR = 0.68 [95% CI 0.68-0.68] and aRR = 0.78 [95% CI 0.77-0.78], respectively). Conclusion: Two dose coverage was more equitable than 3. Differences by immigrant region of birth were substantial. Community-engaged approaches should be re-invigorated to close gaps and promote the bivalent booster.

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. Transcripts were simultaneously translated and written in English and thematic analysis was conducted. An infoposter was identified as a feasible educational tool and was co-designed by researchers and community partners. RESULTS: Participants identified patrilocality (ie, married sons reside with parents, married daughters with in-laws) and patrilineality (ie, sons inherit assets, daughters' husband receives a dowry) as structural precursors to proximal drivers (ie, old-age security) of son preference. Mothers' and grandmothers' value to their families depended strongly on having a son but did not guarantee security. Pressures (ie, internalised discrimination, reproductive coercion) to conceive a son were common after the birth of at least one daughter in the absence of sons. Participants did not know anyone who had a sex selective abortion in Canada; however, traditional sex selection methods (eg, herbal medicines) were mentioned. Our co-designed infoposter entitled 'Truths About Son Preference' addressed three misconceptions identified in discussions. CONCLUSION: This study may be useful to health and social care providers in providing structurally competent and culturally humble counselling and care, particularly after the birth of daughters in the absence of sons. Community engagement is necessary for future intervention development.

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. Design, Setting, and Participants: This retrospective cohort study used linked, population-based demographic and health care data from Ontario, Canada, including all children aged 4 to 17 years registered for universal health insurance on January 1, 2021, across 2 distinct campaigns: for adolescents (ages 12-17 years), starting May 23, 2021, and for children (ages 5-11 years), starting November 25, 2021, through April 24, 2022. Data were analyzed from May 9 to August 2, 2022. Exposures: Immigrant or refugee status and immigration characteristics (recency, category, region of origin, and generation). Main Outcomes and Measures: Outcomes of interest were crude rates of COVID-19 vaccination (defined as ≥1 vaccination for children and ≥2 vaccinations for adolescents) and adjusted odds ratios (aORs) with 95% CIs for vaccination, adjusted for clinical, sociodemographic, and health system factors. Results: The total cohort included 2.2 million children and adolescents, with 1 098 749 children (mean [SD] age, 7.06 [2.00] years; 563 388 [51.3%] males) and 1 142 429 adolescents (mean [SD] age, 14.00 [1.99] years; 586 617 [51.3%] males). Among children, 53 090 (4.8%) were first-generation and 256 886 (23.4%) were second-generation immigrants or refugees; among adolescents, 104 975 (9.2%) were first-generation and 221 981 (19.4%) were second-generation immigrants or refugees, most being economic or family-class immigrants. Immigrants, particularly refugees, were more likely to live in neighborhoods with highest material deprivation (first-generation immigrants: 18.6% of children and 20.2% of adolescents; first-generation refugees: 46.4% of children and 46.3% of adolescents; nonimmigrants: 18.5% of children and 17.2% of adolescents) and COVID-19 risk (first-generation immigrants; 20.0% of children and 20.5% of adolescents; first-generation refugees: 9.4% of children and 12.6% of adolescents; nonimmigrants: 6.9% of children and 6.8% of adolescents). Vaccination rates (53.1% in children and 79.2% in adolescents) were negatively associated with material deprivation. In both age groups, odds for vaccination were higher in immigrants (children: aOR, 1.30; 95% CI, 1.27-1.33; adolescents: aOR, 1.10; 95% CI, 1.08-1.12) but lower in refugees (children: aOR, 0.34; 95% CI, 0.33-0.36; adolescents: aOR, 0.88; 95% CI, 0.84-0.91) compared with nonimmigrants. In immigrant- and refugee-only models stratified by generation, region of origin was associated with uptake, compared with the overall rate, with the lowest odds observed in immigrants and refugees from Eastern Europe (children: aOR, 0.40; 95% CI, 0.35-0.46; adolescents: aOR, 0.41; 95% CI, 0.38-0.43) and Central Africa (children: aOR, 0.24; 95% CI, 0.16-0.35; adolescents: aOR, 0.51,CI: 0.45-0.59) and the highest odds observed in immigrants and refugees from Southeast Asia (children: aOR, 2.68; 95% CI, 2.47-2.92; adolescents aOR, 4.42; 95% CI, 4.10-4.77). Adjusted odds of vaccination among immigrants and refugees from regions with lowest vaccine coverage were similar across generations. Conclusions and Relevance: In this cohort study using a population-based sample in Canada, nonrefugee immigrants had higher vaccine coverage than nonimmigrants. Substantial heterogeneity by region of origin and lower vaccination coverage in refugees persisted across generations. These findings suggest that vaccine campaigns need precision public health approaches targeting specific barriers in identified, undervaccinated subgroups.

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. METHODS AND FINDINGS: Population-based cohort study of resettled refugees arriving in Ontario between April 1, 2008 and March 31, 2017, with one-year follow-up, using linked health and demographic administrative databases. We evaluated associations of resettlement model (GARs, Privately Sponsored Refugees [PSRs], and Blended-Visa Office Referred [BVORs]) by era of arrival (pre-Syrian and Syrian era) and by country cohort, on measures of primary care (PC) navigation using adjusted Cox proportional hazards and logistic regression. There were 34,591 (pre-Syrian) and 24,757 (Syrian era) resettled refugees, approximately half of whom were GARs. Compared with the reference group pre-Syrian era PSRs, Syrian PSRs had slightly earlier PC visits (mean = 116 days [SD = 90]) (adjusted hazard ratios [aHR] = 1.19, 95% CI 1.14-1.23). Syrian GARs (mean = 72 days [SD = 65]) and BVORs (mean = 73 days [SD = 76]) had their first PC visit sooner than pre-Syrian era PSRs (mean = 149 days [SD = 86]), with respective aHRs 2.27, 95% CI 2.19-2.35 and 1.89, 95% CI 1.79-1.99. Compared to pre-Syrian PSRs, Syrian GARs and BVORs had much greater odds of a CHC visit (adjusted odds ratios 14.69, 95% CI 12.98-16.63 and 14.08, 95% 12.05-16.44 respectively) and Syrian PSRs had twice the odds of a CHC visit. CONCLUSIONS: Less timely primary care and lower odds of a CHC visit among PSRs in the first year may be attributed to selection factors and gaps in sponsors' knowledge of healthcare navigation. Improved primary care navigation outcomes in the Syrian era suggests successful health systems engagement.

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). We plot the rates of people tested and confirmed positive for COVID-19 by week from April 19, 2020 to July 31, 2021 across immigration groups. We use logistic regression to estimate adjusted odds ratios of a positive SARS-CoV-2 test, access to testing, and primary care among people with temporary status or permanent residency, compared with people who hold citizenship. RESULTS: A total of 4,146,593 people with citizenship, 914,089 people with permanent residency, and 212,215 people with temporary status were included. Among people with temporary status, 52.1% had "male" administrative sex and 74.4% were ages 20-39, compared with 50.1% and 24.4% respectively among those with citizenship. Of people with temporary status, 4.9% tested positive for SARS-CoV-2 over this period, compared with 4.0% among people with permanent residency and 2.1% among people with citizenship. Adjusted odds of a positive SARS-CoV-2 test among people with temporary status were almost 50% higher (aOR 1.42, 95% CI 1.39, 1.45), despite having half the odds of access to testing (aOR 0.53, 95% CI 0.53, 0.54) and primary care (aOR 0.50, 95% CI 0.49, 0.52). CONCLUSION: Interwoven immigration, health, and occupational policies place people with temporary status in circumstances of precarity and higher health risk. Reducing precarity accompanying temporary status, including regularization pathways, and decoupling access to health care from immigration status can address health inequities.

RéSUMé: OBJECTIFS: Le statut d'immigration temporaire confère des droits, des mesures de protection au travail et un accès aux services limités. Il n'y a pas encore de données de recherche sur les impacts de la pandémie de COVID-19 chez les personnes ayant un statut d'immigration temporaire au Canada. MéTHODE: Nous utilisons des données administratives maillées pour décrire le dépistage du SRAS-CoV-2, les tests positifs et l'utilisation des services de soins de première ligne liés à la COVID-19 en Colombie-Britannique entre le 1er janvier 2020 et le 31 juillet 2021, stratifiées selon le statut d'immigration (citoyenneté, résidence permanente, résidence temporaire). Nous reportons sur des graphiques les taux hebdomadaires de personnes testées et confirmées positives pour la COVID-19 entre le 19 avril 2020 et le 31 juillet 2021 dans les groupes d'immigration. Nous utilisons la régression logistique pour estimer les rapports de cotes ajustés d'un test positif pour le SRAS-CoV-2, de l'accès au dépistage et de l'accès aux soins primaires chez les personnes ayant le statut de résidents temporaires ou permanents comparativement aux personnes ayant la citoyenneté canadienne. RéSULTATS: En tout, 4 146 593 citoyens, 914 089 résidents permanents et 212 215 résidents temporaires ont été inclus. Chez les personnes ayant le statut de résidents temporaires, 52,1 % étaient de sexe administratif « masculin ¼ et 74,4 % avaient entre 20 et 39 ans, contre 50,1 % et 24,4 % respectivement chez les personnes ayant la citoyenneté. Chez les résidents temporaires, 4,9 % avaient obtenu un test positif pour le SRAS-CoV-2 au cours de la période de l'étude, contre 4 % chez les résidents permanents et 2,1 % chez les citoyens. La probabilité ajustée d'un test positif pour le SRAS-CoV-2 chez les personnes ayant le statut de résidents temporaires était près de 50 % plus élevée (RCa 1,42, IC de 95 % 1,39, 1,45), même si leurs probabilités d'accès au dépistage (RCa 0,53, IC de 95 % 0,53, 0,54) et aux soins primaires (RCa 0,50, IC de 95 % 0,49, 0,52) étaient moitié moindres. CONCLUSION: La conjugaison des politiques d'immigration, de santé et de main-d'œuvre met les personnes ayant le statut de résidents temporaires en situation de précarité et de risques accrus pour la santé. La réduction de la précarité qui accompagne le statut temporaire, dont les voies de régularisation, et le découplage entre l'accès aux soins de santé et le statut d'immigration pourraient répondre aux iniquités en santé.

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). Primary outcomes were health system utilization and costs in year 1 in Canada. Multivariable logistic regression was used to test the associations between sponsorship model and major illnesses. RESULTS: We included 23 287 resettled refugees (13 360 GARs, 1544 BVORs, 8383 PSRs) and 93 148 matched Ontario-born. Primary care visits were highest among GARs and lowest in PSRs (median visits [interquartile range], GARs 4[2-6]; BVORs 3[2-5]; PSRs 3[2-5]; P <.001). Emergency department visits and hospitalizations were more common among GARs and BVORs versus PSRs (emergency department: GARs 19.2%; BVORs 23.4%; PSRs 13.8%; hospitalizations: GARs 2.5%; BVORs 3.2%; PSRs 1.1%, P <.001). Mean 1-year health system costs were highest among GARs (mean [standard deviation] $1278 [$7475]) and lowest among PSRs ($555 [$2799]; Ontario-born $851 [9226]). Compared with PSRs, GARs (adjusted odds ratio 1.63, 95% confidence interval 1.47-1.81) and BVORs (adjusted odds ratio 1.52, 95% confidence interval 1.26-1.84) were more likely to have major illnesses. CONCLUSIONS: Health care use and morbidity of PSRs suggests they are healthier and less costly than GARs and BVOR model refugees. Despite a greater intensity of health care utilization than Ontario-born, overall excess demand on the health system for all resettled refugee children is low.

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. We examined contraception use among females with multimorbidity, one chronic condition, and no identified chronic conditions. STUDY DESIGN: We used data from the 2015 to 2016 Canadian Community Health Survey on 15 to 49-year-old females at risk of unintended pregnancy (n = 12,741), comparing females with ≥2 chronic conditions (21.3%) and one chronic condition (27.7%) to those with no identified chronic conditions (51.0%). We used modified Poisson regression to derive adjusted prevalence ratios (aPR) for any contraception vs no contraception, and multinomial logistic regression to derive adjusted odds ratios (aOR) for highly effective, moderately effective, and no contraception vs less effective contraception. RESULTS: Compared to females with no identified chronic conditions, those with multimorbidity were less likely to use any contraception (aPR 0.93, 95% CI 0.89 - 0.98). Females with multimorbidity were more likely than those with no identified chronic conditions to use no contraception (aOR 1.29, 95% CI 1.13 - 1.46), with little to no difference in the use of highly (aOR 1.08, 95% CI 0.91 - 1.29) or moderately effective contraception (aOR 0.98, 95% CI 0.86 - 1.13), vs less effective contraception. There were no differences between females with one chronic condition and no identified chronic conditions. CONCLUSION: The lower overall rate of contraception use in females with multimorbidity reflects a need for more attention to family planning in this population, with prompt and convenient access to highly effective options. IMPLICATIONS: Females with multimorbidity were less likely than those with no identified chronic conditions to use any contraception, and no more likely to use highly or moderately effective versus less effective contraception. Individuals with multimorbidity could benefit from attention to family planning, with prompt and convenient access to highly effective options.

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. OBJECTIVES: a) To describe the linkage of the federal Immigration, Refugees and Citizenship Canada Permanent Resident (IRCC-PR) database with the Manitoba healthcare registry and b) compare data linkage methods and rates between four Canadian provinces accounting for interprovincial mobility of immigrants. METHODS: We compared linkage rates by immigrant's province of intended destination (province vs. rest of Canada). We used external nationwide immigrant tax filing records to approximate actual settlement and obtain linkage rates corrected for interprovincial mobility. RESULTS: The immigrant linkage rates in Manitoba before and after accounting for interprovincial mobility were 84.8% and 96.1, respectively. Linkage rates did not substantially differ according to immigrants' characteristics, with a few exceptions. Observed linkage rates across the four provinces ranged from 74.0% to 86.7%. After correction for interprovincial mobility, the estimated linkage rates increased > 10 percentage points for the provinces that stratified by intended destination (British Columbia and Manitoba) and decreased up to 18 percentage points for provinces that could not use immigration records of those who did not intend to settle in the province (New Brunswick and Ontario). CONCLUSIONS: Despite variations in methodology, provincial linkage rates were relatively high. The use of a national immigration dataset for linkage to provincial repositories allows a more comprehensive linkage than that of province-specific subsets. Observed linkage rates can be biased downwards by interprovincial migration, and methods that use external data sources can contribute to assessing potential selection bias and misclassification.

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). Parents completed weekly questionnaires on health, family functioning, socio-demographics, and public health practices. The outcome was adherence to public health preventive measures measured separately for parents and children. Marginal log-binomial models were fitted using repeated measures of the outcome and predictors. RESULTS: Unemployment (RR 0.67, 95% CI: 0.47, 0.97), apartment living (RR 0.72, 95% CI: 0.53, 0.99), and essential worker in the household (RR 0.74, 95% CI: 0.55, 1.00) were associated with decreased likelihood of adherence among parents; however, no associations were observed for other SDOH, including family income and ethnicity. Furthermore, there was no strong evidence that SDOH were associated with child adherence. The mean number of days/week that parents and children adhered at the start of the study was 6.45 (SD = 0.93) and 6.59 (SD = 0.86), respectively, and this decreased to 5.80 (SD = 1.12) and 5.84 (SD = 1.23) by study end. Children consistently had greater adherence than parents. CONCLUSION: SDOH were predictive of adherence to public health preventive measures among parents but less so in children among our sample of relatively affluent urban families. Adherence was high among parents and children but decreased over time. Equitable approaches to support the implementation of public health guidelines may improve adherence.

RéSUMé: OBJECTIFS: Voir si les déterminants sociaux de la santé (DSS) sont des prédicteurs de conformité aux mesures de prévention sanitaire et décrire l'évolution de la conformité des parents et des enfants au fil du temps. MéTHODE: Nous avons mené une étude longitudinale auprès d'enfants de 0 à 10 ans et de leurs parents dans le cadre de l'étude sur la COVID-19 menée par le groupe de recherche TARGet Kids! dans la région du Grand Toronto, au Canada (avril à juillet 2020). L'étude incluait 335 parents (2 108 observations) et 416 enfants (2 632 observations). Les parents ont rempli un questionnaire hebdomadaire sur la santé, le fonctionnement familial, le profil sociodémographique et les pratiques sanitaires. Le résultat était la conformité aux mesures de prévention sanitaire, mesurée séparément pour les parents et les enfants. Des modèles log-binomiaux marginaux ont été ajustés à l'aide de mesures répétées du résultat et des prédicteurs. RéSULTATS: Le chômage (RR 0,67, IC de 95 % : 0,47, 0,97), la vie en appartement (RR 0,72, IC de 95 % : 0,53, 0,99) et la présence d'un travailleur essentiel dans le ménage (RR 0,74, IC de 95 % : 0,55, 1,00) étaient associés à une probabilité réduite de conformité chez les parents; par contre, aucune association n'a été observée pour les autres DSS, dont le revenu familial et l'ethnicité. Il n'y avait pas non plus d'indications convaincantes d'une association entre les DSS et la conformité chez les enfants. Le nombre moyen de jours/semaine où parents et enfants s'étaient conformés aux mesures de prévention sanitaire au début de l'étude était de 6,45 (S = 0,93) et de 6,59 (S = 0,86), respectivement; ce nombre a diminué pour atteindre 5,80 (S = 1,12) et 5,84 (S = 1,23) à la fin de l'étude. La conformité des enfants était uniformément supérieure à celle des parents. CONCLUSION: Dans notre échantillon de familles urbaines relativement aisées, les DSS étaient des prédicteurs de conformité aux mesures de prévention sanitaire chez les parents, mais dans une moindre mesure chez les enfants. La conformité était élevée chez les parents comme chez les enfants, mais elle a diminué avec le temps. Des stratégies équitables d'appui à l'application des directives sanitaires pourraient améliorer le respect de ces directives.

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. Based on research gaps uncovered in the review, future implementation science research needs to focus on designing, implementing, evaluating, and scaling: effective evidence-based socioeconomic interventions; equity-focused, redistributive, and transformative interventions; comprehensive packages of complementary interventions; interventions to upend root causes of systemic social inequities; collaborative and participatory approaches; interventions that integrate environmental sustainability; and city-level interventions. Failing to consider the environmental dimensions of economic recovery is shortsighted and will ultimately exacerbate social inequities and poverty and undermine economic stability in the long term.

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. METHODS: We conducted a population-based study of 15- to 49-year-old refugees (N = 29,189), nonrefugee immigrants (N = 187,430), and long-term residents (N = 641,385) with and without CMC in Ontario, Canada, with a singleton live birth in 2005 to 2015 and no treatment for mental illness in the 2 years before pregnancy. Modified Poisson regression was used to estimate the relative risk of a psychiatric emergency department visit or hospitalization from conception until 1 year postpartum among women with versus without CMC, stratified by migrant status. An unstratified model with an interaction term between CMC and migrant status was used to test for multiplicativity of effects. RESULTS: The association between CMC and risk of a psychiatric emergency department visit or hospitalization was stronger among refugees (adjusted relative risk [aRR] = 1.87; 95% confidence interval [CI], 1.36 to 2.58) compared to long-term residents (aRR = 1.39; 95% CI, 1.30 to 1.48; interaction P = 0.047). The strength of the association was no different in nonrefugee immigrants (aRR = 1.26; 95% CI, 1.05 to 1.51) compared to long-term residents (interaction P = 0.45). CONCLUSION: Our study identifies refugee women with CMC as a high-risk group for acute psychiatric health care in the perinatal period. Preventive psychosocial interventions may be warranted to enhance supportive resources for all women with CMC and, in particular refugee women, to reduce the risk of acute psychiatric health care in the perinatal period.

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. We examined the association between abortion and region of birth and birth order among Canadian immigrants. METHODS: We conducted a population-based person-years (PY) cohort study in Ontario, Canada using administrative immigration (1991-2012) and health care data (1991-2013). Associations between induced abortion and an immigrant's region of birth were estimated using poisson regression. Rate ratios were adjusted for age, landing year, education, neighborhood income quintile and refugee status and stratified by birth order within regions. RESULTS: Immigrants born in almost all world regions (N = 846,444) were 2-5 times more likely to have an induced abortion vs. those born in the US/Northern & Western Europe/Australia & New Zealand (0.92 per 100 PY, 95% CI 0.89-0.95). Caribbean (Adjusted Rate Ratio [ARR] = 4.71, 95% CI 4.55-4.87), West/Middle/East African (ARR = 3.38, 95% CI 3.26-3.50) and South American (ARR = 3.20, 95% CI 3.09-3.32) immigrants were most likely to have an abortion. Most immigrants were less likely to have an abortion after vs. prior to their 1st birth, except South Asian immigrants (RR = 1.60, 95% CI 1.54-1.66; RR = 2.23, 95% CI 2.12-2.36 for 2nd and 3rd vs 1st birth, respectively). Secondary analyses included further stratifying regional models by year, age, education, income quintile and refugee status. CONCLUSIONS: Induced abortion varies considerably by both region of birth and birth order among immigrants in Ontario.

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. In sensitivity analysis, refugees with secondary migration were matched to the other three groups on country of birth, age and year of arrival (+/- 5 years) and analyzed using conditional logistic regression. Unmatched and matched models were adjusted for age and education. HIV prevalence among secondary and primary refugees and non-refugees was 1.47% (24/1629), 0.82% (112/13,640), 0.06% (7/11,571) and 0.04% (49/114,935), respectively. Secondary migration was a significant effect modifier (p-value = .02). Refugees with secondary migration were 68% more likely to have HIV than refugees with primary migration (PR = 1.68, 95% CI 1.06, 2.68; APR = 1.68, 95% 1.04, 2.71) with a stronger effect in the matched model. There was no difference among non-refugee immigrants. Secondary migration may amplify HIV risk among refugee but not non-refugee immigrant mothers.

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. Eligible studies were observational and experimental which had at least one tangible item provided for free and had at least one quantitative measure of health. Studies were excluded if the intervention was primarily a service and the free good was relatively unimportant; if the good was a medication; or if the data in a study was duplicated in another study. Covidence screening software was used to manage articles for two levels of screening. Data was extracted using an adaption of the Cochrane data collection template. Health outcomes, those that affect the quality or duration of life, are the outcomes of interest. The study was registered with PROSPERO (CRD42017069463). FINDINGS: The initial search identified 3370 articles and 59 were included in the final set with a range of 20 to 252 246 participants. The risk of bias assessment revealed that overall, the studies were of medium to high quality. Among the studies included in this review, 80 health outcomes were statistically significant favouring the intervention, 19 health outcomes were statistically significant favouring the control, 141 health outcomes were not significant and significance was unknown for 28 health outcomes. INTERPRETATION: The results of this systematic review provide evidence that free goods can improve health outcomes in certain circumstances, although there were important gaps and limitations in the existing literature.
