  • 1. TRACKING RATES OF DIABETES AMONGST STATUS ABORIGINAL  AND GENERAL POPULATION  YOUTH IN ALBERTA, CANADA Richard Oster PhD Candidate University of Alberta CDPAC, Ottawa February 8th 2012
  • 2. OUTLINE Background Methods Results Summary
  • 3. BACKGROUND
  • 4. IntroductionBackgroundMethodsResults CANADA’S ABORIGINAL PEOPLESSummary  First Nations and  Canada Alberta Inuit (‘status’ and  ‘non‐status’), as well  First 696 310 97 130 as Métis  Nations  3.8% of total  Inuit 50 340 1 600 population  The contemporary  Métis 388 465 85 240 Aboriginal  population is young,  growing and  Total 1 135 115 183 970 urbanizing Adapted from Statistics Canada, 2006
  • 5. IntroductionBackgroundMethodsResults DIABETES IN STATUS ABORIGINALSSummary  Rapid emergence of type 2 diabetes  Prevalence 2‐5 times higher  Females have higher prevalence, but gap  may be closing
  • 6. IntroductionBackground Prevalence and incidence of diabetes among Methods people aged 20 years or more in AlbertaResultsSummary Oster et al, 2011
  • 7. IntroductionBackgroundMethodsResults DIABETES IN STATUS ABORIGINALSSummary  Perhaps more alarming are reports of  increasing obesity and emerging type 2  diabetes in Aboriginal youth   Those with early‐onset type 2 diabetes  experience a longer duration of disease and  thus have an increased risk of developing  complications 
  • 8. IntroductionBackground Age‐specific diabetes incident case counts and Methods incidence by period in SaskatchewanResultsSummary Dyck et al, 2010
  • 9. IntroductionBackgroundMethodsResults Type 2 diabetes incidence from a tertiary care Summary pediatric Diabetes Education Centre in  Manitoba Dean et al, 2003
  • 10. IntroductionBackgroundMethodsResultsSummary Clinical, metabolic, behavioral, and sociodemographic  risk factors for chronic complications among Navajo  youth with type 2 diabetes Variable Clinical type 2 diabetes N 66 % with A1c > 9.5 43.3% % with waist circumference > 90th 82.5% percentile % with hypertension 35.5% % with hypertriglyceridemia 74.1% % with low HDL 41.1% % with microalbuminuria 31.5% Adapted from Dabelea et al, 2009
  • 11. IntroductionBackgroundMethodsResults IN ALBERTA?Summary  The epidemiology of diabetes  in Aboriginal youth has not  been explored in Alberta   The Alberta Diabetes  Surveillance System (ADSS)  includes administrative data on  youth  OBJECTIVE: To track and compare trends in diabetes rates from 1995 to 2007 for Status Aboriginal and general population youth
  • 12. METHODS
  • 13. IntroductionBackgroundMethodsResults DATA SOURCESummary  Data from 1995‐2007 for youth (< 20 years)  was obtained: physician claims, vital  statistics, hospital discharge data  Diabetes cases were identified using the  National Diabetes Surveillance System  algorithm  Does not differentiate between type 1 and type  2 diabetes  The Status Aboriginal identifier captures  First Nations and Inuit peoples both on‐ and  off‐reserve with Treaty status 
  • 14. IntroductionBackgroundMethodsResults DATA ANALYSESSummary  Crude annual diabetes prevalence and  incidence rates by ethnicity  Odds ratios (OR) were calculated to  compare the likelihood of being a prevalent  case and incident case of diabetes for the  two populations in 2007  Average Annual Percent Changes (AAPC) in  prevalence and incidence from 1995 to 2007  were determined and compared

  • 21. IntroductionBackgroundMethodsResults      TAKE HOME MESSAGESSummary  Diabetes prevalence and incidence has  increased among all Alberta youth  Status Aboriginal youth, males in particular,  experienced a disproportionate growth in  diabetes  If unabated, increasing diabetes in youth  will likely only further perpetuate the  diabetes epidemic in the Status Aboriginal population
