Abstract

BACKGROUND: Indigenous peoples in Canada have higher rates of kidney disease than non-Indigenous Canadians. However, little is known about the risk of kidney disease specifically in the Métis population in Canada.

OBJECTIVE: To compare the prevalence of chronic kidney disease and incidence of acute kidney injury and end-stage kidney disease among registered Métis citizens in Ontario and a matched sample from the general Ontario population.

DESIGN: Population-based, retrospective cohort study using data from the Métis Nation of Ontario's Citizenship Registry and administrative databases.

SETTING: Ontario, Canada; 2003-2013.

PATIENTS: Ontario residents ≥18 years.

MEASUREMENTS: Prevalence of chronic kidney disease and incidence of acute kidney injury and end-stage kidney disease. Secondary outcomes among patients hospitalized with acute kidney injury included non-recovery of kidney function and mortality within 1 year of discharge.

METHODS: Database codes and laboratory values were used to determine study outcomes. Métis citizens were matched (1:4) to Ontario residents on age, sex, and area of residence. The analysis included 12 229 registered Métis citizens and 48 916 adults from the general population.

RESULTS: We found the prevalence of chronic kidney disease was slightly higher among Métis citizens compared with the general population (3.1% vs 2.6%,

LIMITATIONS: The Métis Nation of Ontario Citizenship Registry only captures about 20% of Métis people in Ontario. Administrative health care codes used to identify kidney disease are highly specific but have low sensitivity.

CONCLUSIONS: Rates of kidney disease were similar or slightly higher for Métis citizens in Ontario compared with the matched general population.
