Osteoporosis management and fractures in the Métis of Ontario, Canada

Métis health in Canada: a scoping review of Métis-specific health literature

BACKGROUND

Métis are a culturally unique and distinct population, yet little research has evaluated their health separate from the broader Indigenous population. We sought to explore current literature regarding the health of Métis Peoples in Canada and identify potential trends and gaps.

METHODS

Using the Arksey-O'Malley, 5-stage, scoping review method, we searched PubMed, MEDLINE, iPortal Indigenous Articles Portal Research Tool and pertinent reference lists using the terms "Métis," "health" and "Canada." Two reviewers conducted the initial searches independently, including English articles from 2012 to 2022, and focused on only Métis populations' health within Canada. We described characteristics of the articles and themes for discussion.

RESULTS

Of the 572 articles we identified, we included a total of 28 articles in this scoping review, of which 16 were quantitative, 9 were qualitative and 3 used mixed methods. Thirteen articles used consultation with Métis communities as part of their methods, and 8 extracted data from national surveys. One article focused on children, while all other articles focused on adults. Nine articles used data from across Canada, 6 were based in Ontario, 5 in Alberta and 4 each in British Columbia and Manitoba. Themes included health, well-being and spirituality; mental health and substance use; health conditions and risk factors; access to adequate health resources; and experiences in health care.

INTERPRETATION

Métis-specific health research is lacking in Canada, with a gap in volume, subject matter and diversity in the demographics studied. This review illustrates the need for more research with strong community engagement to further explore Métis health and health service needs.

Fractures in indigenous compared to non-indigenous populations: A systematic review of rates and aetiology

BACKGROUND

Compared to non-indigenous populations, indigenous populations experience disproportionately greater morbidity, and a reduced life expectancy; however, conflicting data exist regarding whether a higher risk of fracture is experienced by either population. We systematically evaluate evidence for whether differences in fracture rates at any skeletal site exist between indigenous and non-indigenous populations of any age, and to identify potential risk factors that might explain these differences.

METHODS

On 31 August 2016 we conducted a comprehensive computer-aided search of peer-reviewed literature without date limits. We searched PubMed, OVID, MEDLINE, CINAHL, EMBASE, and reference lists of relevant publications. The protocol for this systematic review is registered in PROSPERO, the International Prospective Register of systematic reviews (CRD42016043215). Using the World Health Organization reference population as standard, hip fracture incidence rates were re-standardized for comparability between countries.

RESULTS

Our search yielded 3227 articles; 283 potentially eligible articles were cross-referenced against predetermined criteria, leaving 27 articles for final inclusion. Differences in hip fracture rates appeared as continent-specific, with lower rates observed for indigenous persons in all countries except for Canada and Australia where the opposite was observed. Indigenous persons consistently had higher rates of trauma-related fractures; the highest were observed in Australia where craniofacial fracture rates were 22-times greater for indigenous compared to non-indigenous women. After adjustment for socio-demographic and clinical risk factors, approximately a three-fold greater risk of osteoporotic fracture and five-fold greater risk of craniofacial fractures was observed for indigenous compared to non-indigenous persons; diabetes, substance abuse, comorbidity, lower income, locality, and fracture history were independently associated with an increased risk of fracture.

CONCLUSIONS

The observed paucity of data and suggestion of continent-specific differences indicate an urgent need for further research regarding indigenous status and fracture epidemiology and aetiology. Our findings also have implications for communities, governments and healthcare professionals to enhance the prevention of trauma-related fractures in indigenous persons, and an increased focus on modifiable lifestyle behaviours to prevent osteoporotic fractures in all populations.
