Objective Both pregestational and gestational diabetes mellitus (PGDM, GDM) occur more frequently in First Nations (North American Indians) pregnant women than their non-Indigenous counterparts in Canada. We assessed whether the impacts of PGDM and GDM on perinatal and postneonatal mortality may differ in First Nations versus non-Indigenous populations. Design A population-based linked birth cohort study. Setting and participants 17 090 First Nations and 217 760 non-Indigenous singleton births in 1996-2010, Quebec, Canada. Main outcome measures Relative risks (RR) of perinatal and postneonatal death. Perinatal deaths included stillbirths and neonatal (0-27 days of postnatal life) deaths; postneonatal deaths included infant deaths during 28-364 days of life. Results PGDM and GDM occurred much more frequently in First Nations (3.9% and 10.7%, respectively) versus non-Indigenous (1.1% and 4.8%, respectively) pregnant women. PGDM was associated with an increased risk of perinatal death to a much greater extent in First Nations (RR=5.08[95% CI 2.99 to 8.62], p<0.001; absolute risk (AR)=21.6 [8.6-34.6] per 1000) than in non-Indigenous populations (RR=1.76[1.17, 2.66], p=0.003; AR=4.2[0.2, 8.1] per 1000). PGDM was associated with an increased risk of postneonatal death in non-Indigenous (RR=3.46[1.71, 6.99], p<0.001; AR=2.4[0.1, 4.8] per 1000) but not First Nations (RR=1.16[0.28, 4.77], p=0.35) infants. Adjusting for maternal and pregnancy characteristics, the associations were similar. GDM was not associated with perinatal or postneonatal death in both groups. Conclusions The study is the first to reveal that PGDM may increase the risk of perinatal death to a much greater extent in First Nations versus non-Indigenous populations, but may substantially increase the risk of postneonatal death in non-Indigenous infants only. The underlying causes are unclear and deserve further studies. We speculate that population differences in the quality of glycaemic control in diabetic pregnancies and/or genetic vulnerability to hyperglycaemia's fetal toxicity may be contributing factors.

Objective: This study examined the physical and mental health of Cree adults, as well as the personal, clinical, and environmental factors associated with the presence of lifetime anxiety and mood disorders.Methods: Mental health was assessed using the computerised version of the Diagnostic Interview Schedule (CDIS-IV), and standardised instruments were used to assess physical health, addiction severity, and psychological distress in 506 randomly selected participants from 4 Northern Cree communities in Quebec.Results: Overall, 46.1% of participants reported chronic medical problems, 42.1% were current smokers and 34.5% met the DSM-IV criteria for an anxiety or mood disorder. Individuals with an anxiety or mood disorder were younger, predominantly female, and with higher educational levels, and a large proportion (47.7%) met the lifetime criteria for substance dependence. Hierarchical regression determined that anxiety or mood disorders were associated with serious problems getting along with parents, a history of physical and sexual abuse, and a lifetime diagnosis of substance dependence. Overall, 29.7% of Cree adults reported sexual abuse, 47.1% physical abuse, and 52.9% emotional abuse.Conclusions: This study highlights the high rates of physical and mental health problems in Cree communities and the association among parental history of psychological problems, history of abuse, and psychological distress. Participants expressed a desire for additional medical and psychological treatments to address the patterns of abuse, trauma, and mental disorders that are burdening the Cree communities in Northern Quebec.

Background: Infant mortality is higher in Indigenous than non-Indigenous populations, but comparable data on infant morbidity are lacking in Canada. We evaluated disparities in infant morbidities experienced by Indigenous populations in Canada.Methods: We used linked population-based birth and health administrative data from Quebec, Canada, to compare hospitalization rates, an indicator of severe morbidity, in First Nations, Inuit and non-Indigenous singleton infants (< 1 year) born between 1996 and 2010.Results: Our cohort included 19 770 First Nations, 3930 Inuit and 225 380 non-Indigenous infants. Compared with non-Indigenous infants, all-cause hospitalization rates were higher in First Nations infants (unadjusted risk ratio [RR] 2.05, 95% confidence interval [CI] 1.99-2.11; fully adjusted RR 1.43, 95% CI 1.37-1.50) and in Inuit infants (unadjusted RR 1.96, 95% CI 1.87-2.05; fully adjusted RR 1.37, 95% CI 1.24-1.52). Higher risks of hospitalization (accounting for multiple comparisons) were observed for First Nations infants in 12 of 16 disease categories and for Inuit infants in 7 of 16 disease categories. Maternal characteristics (age, education, marital status, parity, rural residence and Northern residence) partly explained the risk elevations, but maternal chronic illnesses and gestational complications had negligible influence overall. Acute bronchiolitis (risk difference v. non-Indigenous infants, First Nations 37.0 per 1000, Inuit 39.6 per 1000) and pneumonia (risk difference v. non-Indigenous infants, First Nations 41.2 per 1000, Inuit 61.3 per 1000) were the 2 leading causes of excess hospitalizations in Indigenous infants.Interpretation: First Nations and Inuit infants had substantially elevated burdens of hospitalizations as a result of diseases of multiple systems. The findings identify substantial unmet needs in disease prevention and medical care for Indigenous infants. [ABSTRACT FROM AUTHOR]

Background: Indigenous populations are disproportionately affected by traumatic brain injury. These populations rely on large jurisdiction surveillance efforts to inform their prevention strategies, which may not address their needs. We examined the incidence and determinants of traumatic brain injury in an indigenous population in the Terres-Cries-de-la-Baie-James health region of the province of Quebec and compared them with the incidence and determinants in 2 neighbouring health regions and in the province overall. Methods: We conducted a retrospective population-based cohort study of patients in Quebec admitted to hospital with incident traumatic brain injury, stratified by health region (Terres-Cries-de-la-Baie-James, Nunavik and Nord-du-Québec), from 2000 to 2012. We used MED-ÉCHO administrative data for case-finding. A subgroup analysis of adults in the Terres-Cries-de-la-Baie- James health region was completed to assess determinants of the severity of traumatic brain injury and patient outcomes. Results: A total of 172 hospital admissions for incident traumatic brain injury occurred in the Terres-Cries-de-la-Baie-James region during the study period. The incidence was 92.1 per 100 000 person-years, and the adjusted incidence rate ratio was 1.84 (95% confidence interval 1.56-2.17) compared with the entire province. The incidence was higher than in the neighbouring nonindigenous population (Nord-du-Québec) but significantly lower than in the neighbouring indigenous population (Nunavik). Determinants of traumatic brain injury in the Terres-Cries-de-la-Baie-James region differed from those in the neighbouring populations and in the entire province. Interpretation: We found that the incidence rates and determinants of traumatic brain injury requiring hospital admission varied greatly between the three regions studied. Community-based surveillance efforts should be encouraged to inform the development of relevant prevention strategies. [ABSTRACT FROM AUTHOR]

Objectives: Diabetes in pregnancy, whether pre-gestational (chronic) or gestational (de novo hyperglycaemia), increases the risk of adverse birth outcomes. It is unclear whether gestational diabetes increases the risk of postnatal morbidity in infants. Cree First Nations in Quebec are at high risk for diabetes in pregnancy. We assessed whether pre-gestational or gestational diabetes may increase infant hospitalisation (an infant morbidity indicator) incidence, and whether this may be related to more frequent infant hospitalisations in Cree and other First Nations in Quebec., Design: Population-based birth cohort study through administrative health data linkage., Setting and Participants: Singleton infants (≤1 year) born to mothers in Cree (n=5070), other First Nations (9910) and non-Indigenous (48 200) communities in rural Quebec., Results: Both diabetes in pregnancy and infant hospitalisation rates were much higher comparing Cree (23.7% and 29.0%) and other First Nations (12.4% and 34.1%) to non-Indigenous (5.9% and 15.5%) communities. Compared with non-diabetes, pre-gestational diabetes was associated with an increased risk of any infant hospitalisation to a greater extent in Cree and other First Nations (relative risk (RR) 1.56 (95% CI 1.28 to 1.91)) than non-Indigenous (RR 1.26 (1.15 to 1.39)) communities. Pre-gestational diabetes was associated with increased risks of infant hospitalisation due to diseases of multiple systems in all communities. There were no significant associations between gestational diabetes and risks of infant hospitalisation in all communities. The population attributable risk fraction of infant hospitalisations (overall) for pre-gestational diabetes was 6.2% in Cree, 1.6% in other First Nations and 0.3% in non-Indigenous communities., Conclusions: The study is the first to demonstrate that pre-gestational diabetes increases the risk of infant hospitalisation overall and due to diseases of multiple systems, but gestational diabetes does not. High prevalence of pre-gestational diabetes may partly account for the excess infant hospitalisations in Cree and other First Nations communities in Quebec., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Aim: Youth mental health is of paramount significance to society globally. Given early onset of mental disorders and the inadequate access to appropriate services, a meaningful service transformation, based on globally recognized principles, is necessary. The aim of this paper is to describe a national Canadian project designed to achieve transformation of mental health services and to evaluate the impact of such transformation on individual and system related outcomes., Method: We describe a model for transformation of services for youth with mental health and substance abuse problems across 14 geographically, linguistically and culturally diverse sites, including large and small urban, rural, First Nations and Inuit communities as well as homeless youth and a post-secondary educational setting. The principles guiding service transformation and objectives are identical across all sites but the method to achieve them varies depending on prevailing resources, culture, geography and the population to be served and how each community can best utilize the extra resources for transformation., Results: Each site is engaged in community mapping of services followed by training, active stakeholder engagement with youth and families, early case identification initiatives, providing rapid access (within 72 hours) to an assessment of the presenting problems, facilitating connection to an appropriate service within 30 days (if required) with no transition based on age within the 11 to 25 age group and a structured evaluation to track outcomes over the period of the study., Conclusions: Service transformation that is likely to achieve substantial change involves very detailed and carefully orchestrated processes guided by a set of values, principles, clear objectives, training and evaluation. The evidence gathered from this project can form the basis for scaling up youth mental health services in Canada across a variety of environments., (© 2018 The Authors Early Intervention in Psychiatry Published by John Wiley & Sons Australia, Ltd.)
