Association of macrosomia with perinatal and postneonatal mortality among First Nations people in Quebec.

Background: High prevalence of infant macrosomia (up to 36%, the highest in the world) has been reported in some First Nations communities in the Canadian province of Quebec and the eastern area of the province of Ontario. We aimed to assess whether infant macrosomia was associated with elevated risks of perinatal and postneonatal mortality among First Nations people in Quebec.

Methods: We calculated risk ratios (RRs) of perinatal and postneonatal mortality by birthweight for gestational age, comparing births to First Nations women (n = 5193) versus women whose mother tongue is French (n = 653 424, the majority reference group) in Quebec 1991-2000.

Birth outcomes and infant mortality among First Nations Inuit, and non-Indigenous women by northern versus southern residence, Quebec.

Background: In circumpolar countries such as Canada, northern regions represent a unique geographical entity climatically, socioeconomically and environmentally. There is a lack of comparative data on birth outcomes among Indigenous and non-Indigenous subpopulations within northern regions and compared with southern regions.

Methods: A cohort study of all births by maternal mother tongue to residents of northern (2616 First Nations (North American Indians), 2388 Inuit and 5006 non-Indigenous) and southern (2563 First Nations, 810,643 non-Indigenous) Quebec, 1991-2000.

Urban Living is Not Associated with Better Birth and Infant Outcomes among Inuit and First Nations in Quebec.

OBJECTIVE: There is limited and inconsistent evidence concerning rural versus urban differences in birth and infant outcomes for Indigenous peoples. We assessed birth and infant outcomes among Inuit, First Nations and French mother tongue groups by rural versus urban residence in Quebec, Canada. STUDY DEIGN: A retrospective birth cohort study of 5,184 First Nations, 2,527 Inuit and 652,940 French mother tongue (the majority reference) births in Quebec, 1991-2000.

Community Remoteness, Perinatal Outcomes and Infant Mortality among First Nations in Quebec.

OBJECTIVE: Little is known about community remoteness in relation to birth outcomes among Indigenous populations. We assessed whether community remoteness matters for perinatal outcomes and infant mortality in Quebec First Nations communities. STUDY DESIGN: A retrospective cohort study of all births (n=11,033) to residents of First Nations communities in Quebec 1991-2000, using linked vital statistics data.

Individual- and Community-Level Disparities in Birth Outcomes and Infant Mortality among First Nations, Inuit and Other Populations in Quebec.

OBJECTIVE: We assessed individual- and community-level disparities and trends in birth outcomes and infant mortality among First Nations (North American Indians) and Inuit versus other populations in Quebec, Canada. METHODS: A retrospective birth cohort study of all births to Quebec residents, 1991-2000. At the individual level, we examined outcomes comparing births to First Nations and Inuit versus other mother tongue women.
