title: Relative prevalence of Aboriginal patients in a Canadian uveitic population.
abstract: OBJECTIVE
  To determine whether the prevalence of Aboriginal patients in a consecutive series of patients with uveitis differs significantly from the prevalence of Aboriginal persons in the general population.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  133 consecutive patients with uveitis.
  
  
  METHODS
  The proportion of Aboriginal patients in a series of 133 consecutive patients with uveitis was compared to the proportion of Aboriginal persons within the general population to determine whether Aboriginal patients were under- or overrepresented in the population with uveitis, relative to their numbers in the population in general. The main outcome measure was the self-reported race of patients. The mean age, sex, and prior disease duration were also compared between Aboriginal and non-Aboriginal patients in the consecutive series.
  
  
  RESULTS
  There was no significant difference (p = 0.84) between the proportion of Aboriginal persons in the uveitis population studied (22 of 133; 16.5%) compared to general population census data (15.5% Aboriginal). Mean age at presentation was 36.8 years in the Aboriginal population versus 47.3 years in the control non-Aboriginal group (p = 0.01). Mean prior disease duration was 20.3 months in the Aboriginal population versus 21.1 months in the control group (p = 0.79). The gender proportion was 68.2% female in the Aboriginal group versus 53.2% female in the non-Aboriginal group (p = 0.02).
  
  
  CONCLUSIONS
  This study finds no statistically significant difference between the prevalence of Aboriginal versus non-Aboriginal persons occurring within a consecutive series of uveitis patients as compared to the general population. Mean age at presentation was significantly younger, and female preponderance was significantly greater in the Aboriginal than in the non-Aboriginal group. Prior disease duration was comparable in the 2 groups.
