Birth and postnatal outcomes among infants of immigrant parents of different admission categories and parents born in Canada: a population-based retrospective study.

BACKGROUND: Most studies of disparities in birth and postnatal outcomes by parental birthplace combine all immigrants into a single group. We sought to evaluate heterogeneity among immigrants in Canada by comparing birth and postnatal outcomes across different immigration categories. METHODS: We conducted a population-based retrospective study using Statistics Canada data on live births and stillbirths (1993-2017) and infant deaths (1993-2018), linked to parental immigration data (1960-2017). We classified birthing parents as born in Canada, economic-class immigrants, family-class immigrants, or refugees, and evaluated differences in preterm births, small-for-gestational-age (SGA) and large-for-gestational-age (LGA) births, stillbirths, and infant deaths among singleton births by group. RESULTS: Among 7 980 650 births, 1 715 050 (21.5%) were to immigrants, including 632 760 (36.9%) in the economic class, 853 540 (49.8%) in the family class, and 228 740 (13.4%) refugees. Compared with infants of Canadian-born birthing parents, infants of each of the 3 immigrant groups had higher risk of preterm birth, SGA birth, and stillbirth, but lower risk of LGA birth and neonatal death. Compared with infants of economic-class immigrants, infants of refugees had higher risk of early preterm birth (0.9% v. 0.8%, adjusted risk ratio [RR] 1.08, 95% confidence interval [CI] 1.01-1.15) and LGA birth (9.2% v. 7.5%, adjusted RR 1.12, 95% CI 1.10-1.15), but lower risk of SGA birth (10.2% v. 11.0%, adjusted RR 0.92, 95% CI 0.90-0.94), while infants of family-class immigrants had higher risk of SGA birth (12.2% v. 11.0%, adjusted RR 1.01, 95% CI 1.00-1.02). Risk of stillbirth, neonatal death, and overall infant death did not differ significantly among immigrant groups. INTERPRETATION: Heterogeneity exists in outcomes of infants born to immigrants to Canada across immigration categories. These results highlight the importance of disaggregating immigrant populations in studies of health disparities.

Institutional trust is a distinct construct related to vaccine hesitancy and refusal.

BACKGROUND: Vaccine hesitancy is driven by a heterogeneous and changing set of psychological, social and historical phenomena, requiring multidisciplinary approaches to its study and intervention. Past research has brought to light instances of both interpersonal and institutional trust playing an important role in vaccine uptake. However, no comprehensive study to date has specifically assessed the relative importance of these two categories of trust as they relate to vaccine behaviors and attitudes. METHODS: In this paper, we examine the relationship between interpersonal and institutional trust and four measures related to COVID-19 vaccine hesitancy and one measure related to general vaccine hesitancy. We hypothesize that, across measures, individuals with vaccine hesitant attitudes and behaviors have lower trust-especially in institutions-than those who are not hesitant. We test this hypothesis in a sample of 1541 Canadians. RESULTS: A deficit in both interpersonal and institutional trust was associated with higher levels of vaccine hesitant attitudes and behaviors. However, institutional trust was significantly lower than interpersonal trust in those with high hesitancy scores, suggesting that the two types of trust can be thought of as distinct constructs in the context of vaccine hesitancy. CONCLUSIONS: Based on our findings, we suggest that diminished institutional trust plays a crucial role in vaccine hesitancy. We propose that this may contribute to a tendency to instead place trust in interpersonally propagated belief systems, which may be more strongly misaligned with mainstream evidence and thus support vaccine hesitancy attitudes. We offer strategies rooted in these observations for creating public health messages designed to enhance vaccine uptake.

Navigating the uncertainty: A novel taxonomy of vaccine hesitancy in the context of COVID-19.

Vaccine hesitancy remains a significant and evolving public health challenge. The COVID-19 pandemic has created a unique decision context with significant uncertainty caused by the novelty of the disease being targeted, unfamiliarity with the vaccines being offered, misinformation, and strong handed government measures. In an effort to extend our understanding of vaccine hesitancy to the high uncertainty decision environment presented by COVID-19, we present a novel taxonomy of the determinants of vaccine hesitancy, based on an inductive analysis of qualitative data gathered during the COVID-19 pandemic. We report on focus group data from a purposive sample of 18 Canadians with varying sociodemographic characteristics and COVID-19 vaccination attitudes. An inductive thematic analysis of this data reveals eight core themes related to vaccine hesitancy: values, trust, social environment, personal anecdotes, environmental fluctuation, prior knowledge, perceived risk & systems of care. We explore these core themes as well as 25 sub-themes, contrasting them with previous models of vaccine hesitancy and suggesting potential strategies for public health professionals.

Fifty years of evidence on perinatal experience among refugee and asylum-seeking women in Organization for Economic Co-operation and Development (OECD) countries: A scoping review.

BACKGROUND: Members of the Organization for Economic Co-operation and Development (OECD) play a significant role in hosting and supporting refugees. Refugees and asylum seekers in OECD countries may face unique challenges in accessing perinatal healthcare. These challenges can impact their use of and experience with perinatal health services leading to poor maternal and infant outcomes. This scoping review describes the general trends in perinatal health research among refugees/asylum seekers in OECD countries over the past fifty years (1970 to 2021) as well as summarizes their perinatal experience. METHODS: Databases including Embase and Medline were searched using relevant key words for "refugee/ asylum seeker", "perinatal ", and " OECD countries.". Articles were excluded if they only involved economic migrants or internally displaced persons, conducted in non-OECD countries, only assessed health behaviors and practices during pregnancy (e.g., smoking), or were published in a language other than English. The final list of articles included 82 unique studies. RESULTS: In the 40 years between 1970 and 2009, very few studies (n = 9) examined perinatal health among refugees/ asylum seekers in OECD countries. However, an increasing trend was observed over the past decade. Early studies (1980 to 2009) focused more on traditional perinatal outcomes; however, from 2010 onwards, studies related to perinatal experience were more likely to emerge in the global health literature. Access to timely prenatal care remains a challenge with failure to address the root causes of the problem in several OECD countries including those with a long history of hosting refugees. The limited availability of interpretation services and the lack of a patient-centered approach to care have also interfered with the perceived quality of care. In addition, perceived isolation and the limited social support experienced by this vulnerable population have negatively impacted their perinatal experiences in several OECD countries. CONCLUSION: Refugee/asylum seekers in OECD countries face a number of challenges during the perinatal period. Policy changes and further research are needed to address access barriers and identify specific interventions that can improve their well-being during this critical period.

Giving birth in a good way when it must take place away from home: Participatory research into visions of Inuit families and their Montreal-based medical providers.

BACKGROUND: Transferring pregnant women out of their communities for childbirth continues to affect Inuit women living in Nunavik-Inuit territory in Northern Quebec. With estimates of maternal evacuation rates in the region between 14% and 33%, we examine how to support culturally safe birth for Inuit families when birth must take place away from home. METHODS: A participatory research approach explored perceptions of Inuit families and their perinatal healthcare providers in Montreal for culturally safe birth, or "birth in a good way" in the context of evacuation, using fuzzy cognitive mapping. We used thematic analysis, fuzzy transitive closure, and an application of Harris' discourse analysis to analyze the maps and synthesize the findings into policy and practice recommendations. RESULTS: Eighteen maps authored by 8 Inuit and 24 service providers in Montreal generated 17 recommendations related to culturally safe birth in the context of evacuation. Family presence, financial assistance, patient and family engagement, and staff training featured prominently in participant visions. Participants also highlighted the need for culturally adapted services, with provision of traditional foods and the presence of Inuit perinatal care providers. Stakeholder engagement in the research resulted in dissemination of the findings to Inuit national organizations and implementation of several immediate improvements in the cultural safety of flyout births to Montreal. CONCLUSIONS: The findings point toward the need for culturally adapted, family-centered, and Inuit-led services to support birth that is as culturally safe as possible when evacuation is indicated. Application of these recommendations has the potential to benefit Inuit maternal, infant, and family wellness.

The impacts of COVID-19 on immigrants and the healthy immigrant effect: Reflections from Canada.

Discussions about potential long-term health consequences of the COVID-19 pandemic on immigrant health and the healthy immigrant effect (HIE) remain unaddressed. Drawing on Canada as a case study, we summarize the primary and secondary impacts of COVID-19 on immigrants. We find that recent and female immigrants as well refugees have fared far worse than either their more established and male counterparts or the Canadian-born population. We then discuss how COVID-19 might influence (or weaken) immigrants' previously documented health advantage. We highlight two structural conditions induced by the pandemic that may alter the health profile of immigrants; namely, immigration policy and delayed medical treatments. Reflections on the requisite data for monitoring and tracking the overall impact of COVID-19 on immigrants' health are included. Finally, we conclude with a discussion of the Canadian patterns and its potential relevance to immigrants and the HIE in the United States.

Childbirth evacuation among rural and remote Indigenous communities in Canada: A scoping review.

PROBLEM: Routine evacuation of pregnant Indigenous women from remote regions to urban centres for childbirth is a central strategy for addressing maternal health disparities in Canada. Maternal evacuation continues despite mounting evidence of its negative impacts on Indigenous women and families. BACKGROUND: Since the 1960s, pregnant Indigenous women living in remote regions in Canada have been transferred to urban hospitals for childbirth. In the following decades, evidence emerged linking maternal evacuation with negative impacts on Indigenous women, their families, and communities. In some communities, resistance to evacuation and the creation of local birthing facilities has resulted in highly diverse experiences of childbirth and evacuation. AIM: A scoping review mapped the evidence on maternal evacuation of Indigenous women in Canada and its associated factors and outcomes from 1978 to 2019. METHODS: We searched MEDLINE, Embase, and CINAHL, and grey literature from governmental and Indigenous organizations. We collated the evidence on maternal evacuation into 12 themes. RESULTS: Factors related to evacuation include (a) evacuation policies (b) institutional coercion (c) remoteness and (d) maternal-fetal health status. Evacuation-related outcomes include (e) maternal-child health impacts (f) women's experience of evacuation (g) financial hardships (h) family disruption (i) cultural continuity and community wellness (ij) engagement with health services (k) self-determination, and (l) quality of health services. DISCUSSION: Numerous emotional, social and cultural harms are associated with evacuation of Indigenous women in Canada. Little is known about the long-term impacts of evacuation on Indigenous maternal-infant health. Evidence on evacuation from remote Métis communities remains a critical knowledge gap.

Pain and Functional Limitations Among Midlife and Older Canadians: The Role of Discrimination, Race and Sense of Belonging.

OBJECTIVES: We drew on fundamental cause theory and the weathering hypothesis to examine how discrimination influences aging for midlife and older adults in Canada. METHODS: Using nationally representative data, we assessed the associations between discrimination and pain and functional limitations among adults 45 years of age and older. Discrimination was measured using a modified version of the Everyday Discrimination Scale. Chi-square tests were performed to check for baseline differences in the dependent and key predictor variables by race. Logistic regression was used to estimate the associations of discrimination, race, and sense of belonging with pain and functional limitations, net of sociodemographic characteristics and SES. RESULTS: Indigenous respondents showed a clear health disadvantage, with higher rates of pain and functional limitations compared to Whites and Asians. Self-reported discrimination was also higher for Indigenous midlife and older adults than for their White and Asian age counterparts. Discrimination had a direct and robust association with pain (OR 1.56, 95% CI 1.31, 1.87) and functional limitations (OR 1.55, 95% CI 1.29, 1.87). However, race moderated the impact of discrimination on functional limitations for Blacks. Finally, a strong sense of belonging to one's local community was protective against pain and functional limitations for all racial groups. DISCUSSION: Future research needs to further examine the impact of discrimination on Indigenous peoples' aging process. High rates of discrimination coupled with a greater burden of pain means that Indigenous midlife and older adults may require additional and targeted health and social service resources to age successfully.

Interactions Between Indigenous Women Awaiting Childbirth Away From Home and Their Southern, Non-Indigenous Health Care Providers.

We examine patient-provider interactions for Indigenous childbirth evacuees. Our analysis draws on in-depth interviews with 25 Inuit and First Nations women with medically high-risk pregnancies who were transferred or medevacked from northern Quebec to receive maternity care at a tertiary hospital in a southern city in the province. We supplemented the patient data with interviews from eight health care providers. Three themes related to patient-provider interactions are discussed: evacuation-related stress, hospital bureaucracy, and stereotypes. Findings show that the quality of the patient-provider interaction is contingent on individual health care providers' ability to connect with Indigenous patients and overcome cultural and institutional barriers to communication and trust-building. The findings point to the need for further training of medical professionals in the delivery of culturally safe care and addressing bureaucratic constraints in the health care system to improve patient-provider communication and overall relationship quality.

The "Hispanic mortality paradox" revisited: Meta-analysis and meta-regression of life-course differentials in Latin American and Caribbean immigrants' mortality.

The literature on immigrant health has repeatedly reported the paradoxical finding, where immigrants from Latin American countries to OECD countries appear to enjoy better health and greater longevity, compared with the local population in the host country. However, no previous meta-analysis has examined this effect focusing specifically on immigrants from Latin America (rather than Hispanic ethnicity) and we still do not know enough about the factors that may moderate the relationship between immigration and mortality. We conducted meta-analyses and meta-regressions to examine 123 all-cause mortality risk estimates and 54 cardiovascular mortality risk estimates from 28 publications, providing data on almost 800 million people. The overall results showed that the mean rate ratio (RR) for immigrants vs. controls was 0.92 (95% CI, 0.84-1.01) for all-cause mortality and 0.73 (CI, 0.67-0.80) for cardiovascular mortality. While the overall results suggest no immigrant mortality advantage, studies that used only native born persons as controls did find a significant all-cause mortality advantage (RR, 0.86; 95% CI, 0.76-0.97). Furthermore, we found that the relative risk of mortality largely depends on life course stages. While the mortality advantage is apparent for working-age immigrants, it is not significant for older-age immigrants and the effect is reversed for children and adolescents.

Are immigrants healthier than native-born Canadians? A systematic review of the healthy immigrant effect in Canada.

OBJECTIVES: Immigrants are typically healthier than the native-born population in the receiving country and also tend to be healthier than non-migrants in the countries of origin. This foreign-born health advantage has been referred to as the healthy immigrant effect (HIE). We examined evidence for the HIE in Canada. DESIGN: We employed a systematic search of the literature on immigration and health and identified 78 eligible studies. We used a narrative method to synthesize the HIE across different stages of the life-course and different health outcomes within each stage. We also examined the empirical evidence for positive selection and duration effects - two common explanations of migrants' health advantage and deterioration, respectively. RESULTS: We find that the HIE appears to be strongest during adulthood but less so during childhood/adolescence and late life. A foreign-born health advantage is also more robust for mortality but less so for morbidity. The HIE is also stronger for more recent immigrants but further research is needed to determine the critical threshold for when migrants' advantage disappears. Positive selection as an explanation for the HIE remains underdeveloped. CONCLUSIONS: There is an absence of a uniform foreign-born health advantage across different life-course stages and health outcomes in Canada. Nonetheless, it remains the case that the HIE characterizes the majority of contemporary migrants since Canada's foreign-born population consists mostly of core working age adults.

Infant mortality among the Canadian-born offspring of immigrants and non-immigrants in Canada: a population-based study.

BACKGROUND: Adult immigrants in Canada have a survival advantage over their Canadian-born counterparts. It is unknown whether migrants are able to transmit their survival advantage to their Canadian-born children. METHODS: Neonatal and postneonatal mortality between the Canadian-born population and 12 immigrant subgroups were compared using 1990-2005 linked birth-infant death records. Age-at-death specific mortality rates and rate differences were calculated by nativity status and maternal birthplace. A chi-square statistic was used to compare group differences in maternal sociodemographic characteristics. Multivariate survival analysis was used to estimate the effect of maternal birthplace on neonatal and postneonatal mortality, net of maternal sociodemographic and infant characteristics. RESULTS: Overall, immigrants had lower rates of neonatal and postneonatal mortality than the Canadian-born population. But the adjusted risk of neonatal mortality was higher for Sub-Saharan African (hazard ratio [HR] = 1.32; 95 % confidence interval [CI] = 1.05, 1.66), Haitian (HR = 2.29, 95 % CI = 1.90, 2.76), non-Spanish Caribbean (HR = 1.38; 95 % CI = 1.01, 1.89), and Pakistani (HR = 1.87; 95 % CI = 1.31, 2.68) migrants relative to Canadian-born women. There were fewer significant disparities in postneonatal death, with higher adjusted risks of mortality observed for Pakistani (HR = 2.67, 95 % CI = 1.77, 4.02) and Haitian (HR = 1.41, 95 % CI = 1.02, 1.97) migrants only. CONCLUSION: Inequalities in infant mortality are more concentrated in the neonatal period. Contingent on surviving the first 27 days after birth, the infants of most immigrants (except those from Haiti and Pakistan) have the same chances of survival as the infants of Canadian-born women. Improvements in prenatal care and access to postpartum care may reduce disparities in infant mortality.

Preterm birth among the Hmong, other Asian subgroups and non-Hispanic whites in California.

BACKGROUND: We investigated very preterm (VPTB) and preterm birth (PTB) risk among Hmong women relative to non-Hispanic whites and other Asian subgroups. We also examined the maternal education health gradient across subgroups. METHODS: California birth record data (2002-2004) were used to analyze 568,652 singleton births to white and Asian women. Pearson Chi-square and logistic regression were used to assess variation in maternal characteristics and VPTB/PTB risk by subgroup. RESULTS: White, Chinese, Japanese, Korean, Asian Indian, and Vietnamese women had 36-59% lower odds of VPTB and 30-56% lower odds of PTB than Hmong women. Controls for covariates did not substantially diminish these disparities. Cambodian, Filipino and Lao/Thai women's odds of VPTB were similar to that of Hmong women. But they had higher adjusted odds of PTB compared to the Hmong. There was heterogeneity in the educational gradient of PTB, with significant differences between the least and most educated women among whites, Chinese, Japanese, Asian Indians, Cambodians, and Laoians/Thais. Maternal education was not associated with PTB for Hmong, Vietnamese and Korean women, however. CONCLUSIONS: Studies of Hmong infant health from the 1980s, the decade immediately following the group's mass migration to the US, found no significant differences in adverse birth outcomes between Hmong and white women. By the early 2000s, however, the disparities in VPTB and PTB between Hmong and white women, as well as between Hmong and other Asian women had become substantial. Moreover, despite gains in post-secondary education among childbearing-age Hmong women, the returns to education for the Hmong are negligible. Higher educational attainment does not confer the same health benefits for Hmong women as it does for whites and other Asian subgroups.

Birth Outcomes of Latin Americans in Two Countries with Contrasting Immigration Admission Policies: Canada and Spain.

BACKGROUND: We delved into the selective migration hypothesis on health by comparing birth outcomes of Latin American immigrants giving birth in two receiving countries with dissimilar immigration admission policies: Canada and Spain. We hypothesized that a stronger immigrant selection in Canada will reflect more favourable outcomes among Latin Americans giving birth in Canada than among their counterparts giving birth in Spain. MATERIALS AND METHODS: We conducted a cross-sectional bi-national comparative study. We analyzed birth data of singleton infants born in Canada (2000-2005) (N = 31,767) and Spain (1998-2007) (N = 150,405) to mothers born in Spanish-speaking Latin American countries. We compared mean birthweight at 37-41 weeks gestation, and low birthweight and preterm birth rates between Latin American immigrants to Canada vs. Spain. Regression analysis for aggregate data was used to obtain Odds Ratios and Mean birthweight differences adjusted for infant sex, maternal age, parity, marital status, and father born in same source country. RESULTS: Latin American women in Canada had heavier newborns than their same-country counterparts giving birth in Spain, overall [adjusted mean birthweight difference: 101 grams; 95% confidence interval (CI): 98, 104], and within each maternal country of origin. Latin American women in Canada had fewer low birthweight and preterm infants than those giving birth in Spain [adjusted Odds Ratio: 0.88; 95% CI: 0.82, 0.94 for low birthweight, and 0.88; 95% CI: 0.84, 0.93 for preterm birth, respectively]. CONCLUSION: Latin American immigrant women had better birth outcomes in Canada than in Spain, suggesting a more selective migration in Canada than in Spain.

Exploring the health consequences of majority-minority neighborhoods: minority diversity and birthweight among native-born and foreign-born blacks.

We examined the association between neighborhood minority diversity and infant birthweight among non-Hispanic US-born black women and foreign-born black women from Sub-Saharan Africa and the non-Spanish speaking Caribbean using 2002-2006 vital statistics birth record data from the state of New Jersey (n = 73,907). We used a standardized entropy score to measure the degree of minority diversity (i.e., non-white multiethnic racial heterogeneity) for each census tract where women lived. We distinguished between four levels of minority diversity, with the highest level representing majority-minority neighborhoods. We estimated mean birthweight for singleton births over this 5-year period using linear regression with robust standard errors to correct for clustering of mothers within census tracts. We found significant differences in mean birthweight by mother's country of origin such that infants of US-born black mothers weighed significantly less than the infants of African and Caribbean immigrants (3130 g vs. 3299 g and 3212 g; p < 0.001). Adjustments for neighborhood deprivation, residential instability, individual-level sociodemographics, maternal health behaviors and conditions, and gestational age did not reduce these origin differences. Minority diversity had a protective effect on black infant health. Women living in low and moderately diverse tracts as well as those in majority-minority neighborhoods had heavier babies (ß = 26.5, 29.8 and 61.2, respectively, p < 0.001) on average than women in the least diverse tracts. The results for majority-minority neighborhoods were robust when we controlled for neighborhood- and individual-level covariates.

Housing supply and residential segregation in Ireland.

The article examines the role of housing supply in ethnic diversity and the residential segregation of Asian, African and eastern European immigrants from Irish nationals in Ireland. Housing supply is defined as the proportions of new housing, private rental accommodation and social housing among all housing units in an electoral district. Multivariate regressions reveal that, among all three housing supply variables, the proportion of private rentals had the largest effect on ethnic diversity and immigrant­ Irish segregation. Areas with higher proportions of private rental units were more ethnically diverse, had greater presences of Africans, Asians and eastern Europeans (as opposed to high concentrations of Irish nationals) and exhibited greater integration between each of the three immigrant groups and Irish nationals. The article concludes with a discussion of immigrant assimilation and questions whether the patterns of residential integration observed would further facilitate other forms of social inclusion for immigrants in Irish society.
