title: Potential years of life lost at ages 25 to 74 among Status Indians, 1991 to 2001.
abstract: BACKGROUND
  Compared with other Canadians, First Nations peoples experience a disproportionate burden of illness and disease. Potential years of life lost (PYLL) before age 75 highlights the impact of youthful or early deaths.
  
  
  METHODS
  The 1991 to 2001 Canadian census mortality follow-up study tracked a 15% sample of adults aged 25 or older over more than a decade. This study examined mortality among people aged 25 to 74-55,600 Status Indians (39,200 on reserve and 16,500 off reserve) and 2,475,700 non-Aboriginal adults-all of whom were enumerated by the 1991 census long-form questionnaire. Age-standardized PYLL rates were calculated, based on the number of person-years at risk before age 75.
  
  
  RESULTS
  Status Indian adults had 2.5 times the risk of dying before age 75, compared with non-Aboriginal adults. Results did not differ greatly by residence on or off reserve. Relative and absolute inequalities were greatest for unintentional and intentional injuries. Socio-economic factors such as income, education, housing and employment explained a substantial share of the disparities in premature death.
  
  
  CONCLUSIONS
  Status Indian adults had higher rates of premature mortality. Socio-economic factors played an important role in those disparities. Injuries were important contributors to both relative and absolute inequalities.
