Francophone and Anglophone perinatal health: temporal and regional inequalities in a Canadian setting, 1981-2008

Underlying Causes of Ethnocultural Inequality in Pregnancy Outcomes: Role of Hospital Proximity

We evaluated the contribution of place of birth to ethnocultural inequality in pregnancy outcomes. We analyzed a cohort of 1,487,723 births between 1998 and 2019 among minority Anglophones and majority Francophones in Quebec, Canada. We estimated the association (adjusted risk ratio, RR; 95% confidence interval, CI) of language with preterm birth and stillbirth, and incorporated interaction terms to determine the contribution of place of birth and distance traveled. Compared with Francophones, minority Anglophones had a greater risk of preterm birth (RR 1.03; 95% CI 1.01-1.06) and were less likely to deliver farther from home (RR 0.95; 95% CI 0.94-0.95). Anglophones who delivered close to home had a higher risk of preterm birth (RR 1.07; 95% CI 1.04-1.11), whereas Anglophones who delivered farther had a lower risk (RR 0.69; 95% CI 0.64-0.75). Patterns were similar for stillbirth. Ethnocultural inequality in adverse birth outcomes may be influenced by place of birth.

Stillbirth Among Arab Women in Canada, 1981-2015

OBJECTIVES

The Arabic-speaking population is increasing in Europe and North America. Evidence suggests that Arab migrants have a greater risk of adverse birth outcomes than nonmigrants, but the risk of stillbirth is largely understudied. We examined inequality in stillbirth rates between Arab women and the French and English majority of women in Quebec, Canada.

METHODS

We conducted a retrospective study of all births in Quebec from 1981 through 2015. We computed stillbirth rates by period and cause of death, and we used log binomial regression to estimate the association between Arabic mother tongue and stillbirth, adjusted for maternal characteristics.

RESULTS

Stillbirth rates per 1000 births overall were lower among women with Arabic mother tongue (3.89) than among women with French or English mother tongue (4.52), and rates changed little over time. However, Arabic-speaking women from Arab countries had a higher adjusted risk of stillbirth than French- or English-speaking women (risk ratio = 1.23; 95% confidence interval, 1.07-1.42). Congenital anomalies, termination of pregnancy, and undetermined causes contributed to a disproportionate number of stillbirths among women with Arabic mother tongue compared with the French- and English-speaking majority.

CONCLUSIONS

Arabic-speaking women from Arab countries have higher risks of stillbirth compared with the French and English majority in Quebec. Strategies to reduce stillbirth risk among Arabic speakers should focus on improving identification of causes of death.

Linguistic mortality gradients in Quebec and the role of migrant composition

OBJECTIVE

Anglophones and Allophones in Quebec (Canada) have lower mortality than Francophones, despite being linguistic minorities. This study assesses whether (1) language is a risk factor for mortality after accounting for migrant composition and (2) interprovincial migrants differ in mortality with respect to Quebec-born individuals.

METHODS

We analyzed death records between 2004 and 2008 from Quebec (all-cause and main causes) and population data from the 2006 census to estimate age-adjusted mortality rates according to language and migrant status. Risk ratios by language and migrant status, adjusted for age, sex, and socioeconomic status, were estimated using Poisson generalized estimating equations.

RESULTS

Francophone Quebec-borns had the highest mortality. Among Quebec-borns, Anglophones [RR= 0.85, 95% CI (0.79-0.91)] and Allophones [RR = 0.16, 95 %CI (0.12-0.22)] had lower mortality relative to Francophones. Interprovincial migrants had lower mortality (Anglophones [RR = 0.58, 95% CI (0.53-0.63)], Francophones [RR = 0.55, 95% CI (0.50-0.60)]) relative to Francophone Quebec-borns (Allophones were excluded due to small sample size). Among immigrants, mortality was lower for Francophones [RR = 0.62, 95% CI (0.57-0.67] and Allophones [RR = 0.35, 95% CI (0.31-0.38], but not Anglophones [RR = 0.92, 95% CI (0.84-1.01)], relative to Francophone Quebec-borns.

CONCLUSION

In Quebec, linguistic disparities in mortality remained after accounting for migrant status, and both Francophone and Anglophone interprovincial migrants in Quebec had lower mortality than Quebec-born Francophones. Public health initiatives to reduce linguistic disparities in health should account for migrant status.

Emerging Lingo-Cultural Inequality in Infant Autopsy in Quebec, Canada

We investigated trends in infant autopsy for Francophones and Anglophones in Quebec, Canada. Using death certificates, we extracted 8214 infant deaths between 1989 and 2013. We computed rates of non-autopsy by language, socioeconomic disadvantage, age at death, and period. Using Kitagawa's method, we decomposed non-autopsy rates over time for both language groups. Infant non-autopsy rates increased from 38.6 to 56.2 per 100 for Francophones, and from 41.2 to 57.2 per 100 for Anglophones, between 1989-1995 and 2008-2013. Trends in English-speakers were driven by socioeconomically disadvantaged Anglophones, and were accelerated by a larger proportion of deaths in this group over time. For French-speakers, rates increased in all socioeconomic groups. The increase in non-autopsy rates was larger at early neonatal ages for both languages. These findings suggest that disadvantaged Anglophones are less likely to use infant autopsy over time, and that rates can be improved by targeting early neonatal deaths.

Stillbirth in an Anglophone minority of Canada

OBJECTIVES

We assessed trends in stillbirth over time for Francophones and Anglophones of Quebec, a large Canadian province with publically funded health care and an English-speaking minority.

METHODS

We calculated stillbirth rates for Francophones and Anglophones, and estimated hazard ratios (HR) by decade from 1981 to 2010, adjusting for maternal characteristics. We analyzed temporal trends by gestational interval and cause of fetal death.

RESULTS

Stillbirth rates decreased in Quebec during the three decades, due to improved rates in Francophones. Rates decreased for Anglophones in 1991-2000, but increased in 2001-2010 at term, during the second trimester, and for most causes of fetal death. In the 2000s, the hazard of stillbirth for Anglophones was nearly the same as the hazard for Francophones in the 1980s (HR 0.93, 95 % confidence interval 0.82, 1.05).

CONCLUSIONS

Stillbirth rates declined in both Francophones and Anglophones before the turn of the century, but increased thereafter for Anglophones, suggesting that linguistic inequalities in stillbirth may be emerging in Quebec. Linguistic status may be a useful marker for surveillance of inequalities in stillbirth.

Contribution of local area deprivation to cultural-linguistic inequalities in foetal growth restriction: trends over time in a Canadian metropolitan centre

This study investigated temporal trends in heterogeneity of foetal growth restriction across neighbourhood deprivation levels for two culturally distinct communities (Anglophones and Francophones) in a North American metropolitan centre. Inequalities in foetal growth restriction related to deprivation fell from 1989 to 2008 for Francophones, but initial improvements for Anglophones later reversed with a rise in poor foetal growth in the most materially disadvantaged and, unexpectedly, advantaged areas as well. Inequalities in foetal growth restriction related to neighbourhood material deprivation may be emerging in this minority Anglophone population. Potential mechanisms underlying these trends are discussed, as well as implications for perinatal health policy.
