Abstract
Inuit are the smallest Aboriginal group in Canada. Inuit women are at much higher risks of adverse birth outcomes than their non-indigenous counterparts. Both fetal and infant mortality has been reported to be much higher among Canadian Inuit vs. non-indigenous populations in some regional studies. Both individual and community-level risk factors may affect Inuit birth outcomes. Little is known about the relationships between community characteristics and Inuit birth outcomes. Understanding the effects of community-level risk factors may be critically important for developing effective maternal and infant health promotion programs to improve birth outcomes in Inuit communities.
In a postal code linkage-based birth cohort study based on the already linked stillbirth/live birth/infant death data files for all births in Quebec, from 1991 to 2000, we assessed the effects of community characteristics on Inuit birth outcomes. While appropriate and feasible, birth outcomes data on another major Aboriginal group, First Nations, are also presented. We first assessed individual- and community-level disparities and trends in birth outcomes and infant mortality among First Nations and Inuit versus other populations in Quebec. Then we studied trends in Inuit, First Nations and non- Aboriginal birth outcomes in the rural and northern regions of Quebec. Because there is limited and inconsistent evidence concerning rural versus urban differences in birth and infant outcomes for Indigenous peoples, we investigated birth and infant outcomes among Inuit, First Nations and French (the majority in Quebec) mother tongue groups by rural versus urban residence in Quebec. Finally, since there was a lack of data on the safety of midwife-led maternity care in remote or Aboriginal communities, we examined birth outcomes by primary birthing attendant type in two sets of remote Inuit communities.
We found large and persistent disparities in fetal and infant mortality among First Nations and Inuit versus other populations in Quebec based on individual- or community-level assessments. There was also a disconcerting rise of some mortality outcomes for births to First Nations and Inuit mother tongue women and to women in predominately First Nations and Inuit communities, in contrast to some improvements for births to non- Aboriginal mother tongue women and to women in predominately non-Aboriginal communities in rural or northern Quebec. Living in urban areas was not associated with better birth and infant outcomes for Inuit and First Nations in Quebec despite universal health insurance coverage. Risks of perinatal death were somewhat but not significantly higher in the Hudson Bay communities with midwife-led maternity care as compared to the Ungava Bay communities with physician-led maternity care. Our findings are inconclusive, although the results excluding extremely preterm births are more reassuring concerning the safety of midwife-led maternity care in remote Aboriginal communities.
Our results strongly indicate a need for improved socioeconomic conditions, perinatal and infant care for First Nations and Inuit peoples, no matter where they live (remote northern, rural or urban areas). Further routine surveillance data are needed for assessing the safety and improving the quality of midwife-led maternity care in Nunavik.
