RT Journal Article SR Electronic T1 A comparison of coronary heart disease event rates among urban Australian Aboriginal people and a matched non-Aboriginal population JF Journal of Epidemiology and Community Health JO J Epidemiol Community Health FD BMJ Publishing Group Ltd SP 315 OP 319 DO 10.1136/jech.2009.098343 VO 65 IS 4 A1 Pamela J Bradshaw A1 Helman S Alfonso A1 Judith Finn A1 Julie Owen A1 Peter L Thompson YR 2011 UL http://jech.bmj.com/content/65/4/315.abstract AB Background Age-specific death from cardiovascular disease among Australian Aboriginals is estimated to be four to seven times that of general population, and the major cause of premature death. There is little reliable information on the incidence of coronary heart disease (CHD). This study compares CHD event rates in urban-dwelling Aboriginal people and the general population.Methods The Perth Aboriginal Atherosclerosis Risk Study (PAARS) cohort was assessed at baseline (1998/1999) and 913 participants followed-up to 2006. A comparison group of age-matched, sex-matched and postcode-matched non-Aboriginals (n=3582) were selected from the Perth, Western Australia, Electoral Roll. Electronic record linkage captured prior CHD and first CHD events in both groups. The rates of first CHD events (hospital admission or CHD death) per 1000 person years (PY) and incidence rate ratios (IRR) were calculated.Results The event rate for the PAARS population was 14.9 per 1000 PY (95% CI 12.3 to 18.2) versus 2.4 (1.9 to 3.1) for the general population. The IRR was 6.1 (4.5 to 8.4). For Aboriginal men the rate was 15.0 (11.2 to 20.0) versus 3.8 (2.5 to 5.0) per 1000 PY, with age-specific rates being two to five times that of non-Aboriginals. Incidence for Aboriginal women was 15.0 (11.5 to 19.5) versus 1.4 (0.9 to 2.1) with age-specific rates being 8–25 times that of non-Aboriginals.Conclusions Age and sex-specific CHD event rates in urban Aboriginals far exceeded that of a matched general population. Events occurred at a much younger age among the Aboriginal participants and were equally excessive among men and women.
