RESUMO
Understanding the barriers to and facilitators of cancer screening programs among Indigenous populations remains limited. In the spirit of mutual respect, this co-led, collaborative project was carried out between the Métis Nation of Alberta and Screening Programs from Alberta Health Services (AHS). This scoping review assessed the cancer screening literature for available questionnaires and then identified themes and suitable questions for a Métis-specific cancer screening questionnaire. Literature searches on cervical, breast, and colorectal cancer screening programs and related concepts were conducted in electronic databases, including the Native Health Database, MEDLINE (Ovid), PsycINFO, PubMed, PubMed Central, CINAHL, MEDLINE (Ebsco), Psychology & Behavioral Sciences Collection, and Web of Science. Grey literature was collected from AHS Insite, Open Archives Initiative repository, American Society of Clinical Oncology, European Society of Medical Oncology, Google, and Google Scholar. 135 articles were screened based on the eligibility criteria with 114 articles selected, including 14 Indigenous-specific ones. Knowledge, attitude, belief, behaviour, barrier, and facilitator themes emerged from the review, but no Métis-specific cancer screening instruments were found. Thus, one was developed using existing cancer screening instruments, with additional questions created by the project team. A survey of the Métis population in Alberta will use this questionnaire and provide data to address the burden of cancer among Métis people.

BACKGROUND: Diabetes in pregnancy is an important public health concern for Indigenous populations. We sought to evaluate the prevalence and outcomes of pre-existing and gestational diabetes among Métis pregnancies compared with other pregnancies in Alberta, Canada. METHODS: We conducted a retrospective cohort study using administrative health data from 2006 to 2016 and the Métis Nation of Alberta Identification Registry to compare the prevalence of pre-existing and gestational diabetes among all singleton Métis births with non-Métis births. We compared 10 maternal and neonatal outcomes using adjusted odds ratios (ORs) and 95% confidence intervals (CIs) in multivariable analyses. RESULTS: The study population included 7902 Métis and 471 886 non-Métis births. The age-standardized prevalence of pre-existing diabetes was 1.7% (95% CI 1.4%-2.1%) for Métis and 1.1% (95% CI 1.1%-1.2%) for non-Métis pregnancies. For gestational diabetes, the age-standardized prevalence was 6.3% (95% CI 5.6%-6.9%) for Métis and 5.4% (95% CI 5.3%-5.4%) for non-Métis pregnancies. After adjusting for parity, maternal weight, age, smoking during pregnancy and material and social deprivation, Métis pregnancies had 1.72 times higher prevalence of preexisting diabetes (adjusted OR 1.72, 95% CI 1.15-2.56) and 1.30 times higher prevalence of gestational diabetes (adjusted OR 1.30, 95% CI 1.08-1.57) than non-Métis pregnancies. Métis pregnancies with pre-existing diabetes had nearly 3 times the odds of developing preeclampsia (adjusted OR 2.96, 95% CI 1.27-6.90), while those with gestational diabetes had 48% higher odds of large-for-gestational-age infants (adjusted OR 1.48, 95% CI 1.00-2.19). INTERPRETATION: Métis pregnancies have an increased prevalence of pre-existing and gestational diabetes than non-Métis pregnancies and an elevated risk of some perinatal outcomes. Interventions to tackle these health inequities should address both physiologic and cultural dimensions of health, informed by Métis perspectives.
