Prevalence and Incidence of Rheumatoid Arthritis in Canadian First Nations and Non-First Nations People: A Population-Based Study.

ABSTRACT:

Background

The aim of this study was to determine the prevalence, incidence, and onset age at rheumatoid arthritis (RA) diagnosis in First Nations (FN) and non-FN populations in Manitoba, Canada.

Methods

Population-based administrative health records from April 1, 1995, to March 31, 2010, were accessed for all Manitobans. The FN population was identified using the Federal Indian Registry File. Crude and adjusted RA prevalence and incidence rates (adjusted for age, sex, health region of residence) were compared using Poisson regression and reported as relative rates (RRs) with 95% confidence intervals (CIs). Mean (CI) diagnosis age and physician visits were compared with Student t tests.

Results

Rheumatoid arthritis crude prevalence increased between 2000 and 2010 to 0
