ObjectivesLack of consistent and relevant Indigenous identifiers in Canadian data sources leads to misclassification and under-recognition of the health and social issues impacting Indigenous Peoples, further perpetuating the harms of colonization. We are evaluating and optimizing our approach for identifying First Nations (FN) individuals in administrative data in Manitoba.
MethodsIn partnership between the First Nations Health and Social Secretariat of Manitoba and the Manitoba Centre for Health Policy, we sought to evaluate to what extent four distinct Manitoba datasets derived from surveillance and social programs were able to identify FN individuals among a cohort of children in low-income Winnipeg neighbourhoods between 2005-2016. In choosing data sources to identify FNs, the population and research question were considered.
We then compared the number of FNs identified in each dataset to the First Nations population research file, considered gold standard, but cognizant of its roots in colonial systems of registration.
ResultsThe total cohort comprised N=78,864; among these, n=27,347 children were identified as FN in either the FN registry or at least one of the datasets. The FN registry was the most sensitive dataset and identified 85.7% of these individuals. The two program datasets identified 58.2% and 46.2%, and the surveillance-based datasets each identified less than 10%.
The First Nations Registry is critical to accurately identify FN individuals. Our analyses demonstrated that without it we would miss 23.5% of those identified as FN in at least one other dataset. However, using it alone could potentially cause us to miss 15% of FN individuals identified in other datasets.
The proportions of FN individuals that would be missed by excluding any of the other datasets were smaller (<6%).
ConclusionWe found inconsistent FN identification across the datasets evaluated. Among the issues is that some datasets rely on self-identification. In Manitoba, no single administrative dataset can reliably and comprehensively identify FN individuals, and linking multiple datasets together is currently our best approach.

ObjectiveManitoba has one of the highest incarceration rates among Canadian provinces, and because of Canada's racist and colonial policies, the number of Métis women in custody is disproportionately high. In this study, we examined birth outcomes among Métis and all other Manitoba women who were incarcerated while pregnant.
ApproachUsing linked administrative health and justice system data, we developed a 2004-2017 cohort of mother-infant dyads with a live birth (n= mothers; n= infants). We identified all Métis mother-infant dyads, and then divided them into 3 mutually exclusive groups: a) prenatal incarceration; b) post-natal incarceration; c) no incarceration. We developed matched comparison groups for each exposure based on Métis identity, maternal age, geography and income, and, after adjusting for other potentially confounding variables (e.g., maternal age, maternal mental health, and socioeconomic factors), we examined risk differences in birth outcomes among Métis women and infants between exposure groups.
ResultsThe cohort included n=534 mothers who were incarcerated while pregnant (a), n=1,677 mothers incarcerated postnatally (b), and n=14,084 mothers never incarcerated (c). When we compared prenatal vs postnatal incarceration (a vs b), we found that women incarcerated during the prenatal period were more likely to have a low birth weight infant (RD: 4.2, 95% CI: 3.0, 5.4), preterm birth (RD: 5.1, 95% CI: 3.7, 6.5) or Caesarean birth (RD: 5.5, 95% CI: 3.8, 7.1) and were less likely to have a large-for-gestational-age infant (RD: -3.8, 95% CI: -5.1, -2.5) or to initiate breast feeding (-3.4, 95% CI: -5.5, -1.3). In the prenatal vs no incarceration comparison (a vs c), the same outcomes were statistically significant as above; however, the risk differences were even more pronounced.
ConclusionPrenatal incarceration is associated with poor birth outcomes for all mothers and infants in Manitoba; however, Métis women and children are disproportionately affected, further perpetuating inequities they may already experience. Canadians must acknowledge the harms of racist policies and practices, and work to support the health and well-being of Métis people.

IntroductionAdministrative data studies routinely report that First Nations mothers and children experience a disproportionate burden of poor health. Due to the nature of administrative data, research often takes a deficits-oriented approach. First Nations health research needs to consider the role that community- and individual-level strengths play in promoting wellbeing and examine how these interact with the delivery and outcomes of health programs.
Objectives and ApproachThe First Nations Health and Social Secretariat of Manitoba (FNHSSM) and the University of Manitoba partnered to construct measures of community-level strengths that can be linked with administrative data to examine the delivery and outcomes associated with population health programs delivered in First Nations communities.
We linked data from the FNHSSM-administered Regional Health Survey (RHS) with administrative data housed in the Manitoba Population Research Data Repository. We identified 60 questions from the child, youth, and adult versions of the RHS to measure community strengths. We used principal component analysis to identify strength-based constructs. We used Eigen values and percent of variance explained to determine the final number of factors. We used random group resampling and bootstrap methods to test for community-level homogeneity. Community-level factor scores were calculated as the scaled combination of RHS questions within each factor and averaged to the community.
ResultsWe identified 12 constructs of community strength: 5 from child responses, 4 from youth, and 3 from adult responses. Strength-based constructs common to all age groups included knowledge of traditional language, involvement in cultural events, and connection with community.
Conclusion / ImplicationsColonial approaches to health research perpetuate deficit-based dialogues and negative portrayal of First Nations peoples. First Nations health research should consider how community strengths promote health and interact with program delivery. Including measures of community strength leads to richer understandings of factors that promote wellness among First Nations peoples.

IntroductionEarly education outcomes influence children's educational trajectories with long-term effects extending into adulthood. Aboriginal peoples face numerous systemic barriers to academic success. It remains unknown if full-day kindergarten (FDK) is associated with improved academic outcomes among Metis children – a distinct Aboriginal people recognized by the Canadian Constitution.
Objectives and ApproachThe Manitoba Metis Federation and the Manitoba Centre for Health Policy partnered to identify whether FDK was associated with improved short- and long-term outcomes among Metis children. We created a cohort of Metis children by linking several provincial databases held in the Manitoba Population Research Data Repository (1998-2011). Education data were used to identify all Metis children who attended FDK (n=247) vs half day kindergarten (HDK; n=547). FDK children were matched by age and sex to children in HDK. We used a step-wedged design and applied propensity scores to adjust for measured confounding. We tested for differences in grades 3, 7, 8 outcomes and high school graduation using generalized linear models.
ResultsFDK children were more likely to live in a low-income neighbourhood. 72% FDK and 74% HDK students met or approached numeracy expectations in grade 3; and 55% FDK and 48% HDK met or approached numeracy expectations in grade 7. For reading expectations, 77% FDK and 75% HDK met or approached grade 3 reading expectations; in grade 8, 62% in each group met or approached expectations for reading and writing. High school graduation rate for FDK children was 84% and for HDK children was 64%. After adjusting for confounding we found FDK children were more likely to graduate high school than HDK children; other outcomes were non-significant.
Conclusion / ImplicationsKindergarten programs may be insufficient to overcome structural barriers that Metis children face. Culturally appropriate education strategies are needed to support improved outcomes amongst this population.

IntroductionIn Manitoba, low-income pregnant women are eligible for the Healthy Baby Prenatal Benefit (HBPB), a prenatal income supplement. Research has demonstrated positive outcomes associated with HBPB, but it remains unknown if Metis women and children – who are of mixed European and Aboriginal descent and one of the most marginalized populations in Canada -- benefit from the program.
Objectives and ApproachThe Manitoba Metis Federation and the Manitoba Centre for Health Policy partnered to determine the impact of HBPB on Metis newborn and early childhood outcomes. We included all Metis women giving birth in Manitoba 2003-2011 who received income assistance during pregnancy (n=4,852), adjusting for differences between those receiving (n=3,681) and not receiving (n=1,171) HBPB with propensity score weighting. We used multi-variable regressions to compare outcomes between groups: breastfeeding initiation, low birth weight, preterm birth, small- and large-for-gestational age, Apgar scores, birth hospitalization length of stay (LOS), neonatal readmissions, infant hospitalizations, vaccinations at age 1 and 2, and child development scores at kindergarten.
ResultsHBPB receipt was associated with reductions in low birth weight (adjusted Relative Risk (aRR): 0.74 (95% CI: 0.58-0.94)) and preterm births (aRR: 0.78 (0.65-0.94)), and increases large-for-gestational age births (aRR: 1.21 (1.06-1.39)) and neonatal readmissions (aRR: 1.58 (1.05-2.37)). Birth hospitalization LOS was lower for newborns whose mothers received HBPB (Mean Difference 0.29 days). HBPB was associated with increases in vaccinations for children aged 1 (aRR: 1.08 (1.00-1.15)) and 2 (aRR: 1.12 (1.05-1.18)). No significant associations were found for small-for-gestational age births, Apgar scores, breastfeeding initiation, infant hospitalizations or child development scores.
Conclusion / ImplicationsA modest unconditional prenatal income supplement to low-income Metis women was associated with improved birth outcomes and child vaccinations; however, an association with increased neonatal readmissions warrants further exploration. Lack of significant associations between HBPB and child development measures suggests more sustained support may be necessary to improve longer-term outcomes.

ObjectivesIndigenous children in Canada, including Metis children, are taken into care by the child welfare system at a disproportionately high rate. The objective of this study was to explore factors related to having a child taken into care from Metis families in Manitoba, and specifically from Metis mothers experiencing incarceration.
ApproachThe cohort comprised all mother-child dyads in Manitoba, Canada with live births between Jan 1, 2004-Dec 31, 2014. The factors we examined included the mother experiencing incarceration after the birth of a child, having prior interaction with the legal system, socioeconomic status, maternal age, and mother's mental health disorder diagnoses. Using the Cox proportional hazards model, unadjusted and adjusted hazard ratios describing the risk of a child being taken into care by five years of age were generated for three exposure groups: no incarceration, prenatal incarceration, and postnatal incarceration.
ResultsBefore adjustment, mothers experiencing incarceration after the birth of a child had greater risk of having a child taken into care (HR 9.3; 95% CI 7.7-11.3) compared with women who did not experience incarceration; after adjusting for measured confounders, their elevated risk dropped to aHR 6.1 (5.0-7.4). After further adjustment for prior custody in the prenatal period, mothers experiencing incarceration had 3.8 times the risk (3.0-5.0), and after adjusting for maternal mental health disorders, this dropped to 2.6 times the risk (2.0-3.4). In fully adjusted models, other factors associated with having a child taken into care included receiving diagnoses for a substance use disorder (aHR 2.6; 2.1-3.2) and for psychosis (aHR 2.4; 1.4-4.1) during the five years prior to the child's birth.
ConclusionDue to colonialism, Metis women experience high levels of social and mental health complexity, placing their children at increased risk of being taken into care. Responding to the Truth and Reconciliation Commission's Calls to Action to redress the harms of colonialism is necessary to support Metis children's health and well-being.

ObjectivesOver three decades ago, the Aboriginal Justice Inquiry identified structural racism in Canada's justice system. Although rates of youth criminal charges and incarcerations have declined substantially since then, it is unclear whether First Nations youth are treated differently than non-First Nations youth for similar offences. Our study addressed this question.
ApproachThis retrospective cohort study of youth born 1991-2001 and living in Manitoba between ages 12-17 used whole-population linked administrative data to identify youth charged with a crime (N=13,543). First Nations youth (n=7,081) were compared with all other Manitoba (AOM) youth (n=6,462) on whether their criminal charge proceeded or was dropped, deferred or diverted. The study applied an intersectionality theoretical framework. Individual (age, type and severity of charge, ever in child protection care, youth and/or mother diagnosed mental disorder, maternal incarceration, number of siblings, urban/rural residence) and social strata (First Nations identity, income, sex) factors were adjusted for using multi-level models.
ResultsAfter accounting for other factors, First Nations youth had a higher risk of a charge proceeding than AOM (adjusted Relative Risk (aRR) 1.16, 95% CI 1.12-1.20). There was no difference in charges proceeding for male First Nations youth compared with male AOM, whereas among females, the risk was greater for First Nations (aRR 1.31, 95% CI 1.26-1.36). Low income and a history of being in the care of the child protection system increased the risk of charges proceeding for AOM only (aRR 1.16, 95% CI 1.13-1.18; aRR 1.13, 95% CI 1.07-1.20); for First Nations, there was no increased risk of charges proceeding associated with these intersecting factors.
ConclusionThese findings provide quantitative evidence of the intersecting structural racism in the youth criminal justice system previously identified by First Nations leaders. Future research will follow this cohort to determine whether more judicial sanctions are applied to First Nations youth throughout the justice process, including within criminal courts and corrections.
