Background: In Australia, Aboriginal adults experience higher levels of poor oral and general health than the non-Aboriginal population. This study compared self-rated oral and general health among Aboriginal adults in regional South Australia with participants in the National Survey of Adult Oral Health (NSAOH).
Methods: Data were obtained from the Indigenous Oral Health Literacy Project (IOHLP) based in South Australia. Three sub-populations from the NSAOH were utilised for comparison: National Aboriginal, National non-Aboriginal and South Australian Regional Non-Aboriginal adults. All data were standardised by age group and sex, utilising Census data.
Results: Just over 70% of South Australian Regional Aboriginal participants gave a rating of 'excellent, very good or good' for general health, more than 17% lower than each of the other groups. Just over 50% rated their oral health highly, 20% fewer than the proportion for each other group. Stratifying by key socio-demographic factors did not account for all differences.
Conclusions: Proportionally fewer South Australian Regional Aboriginal adults had high ratings of oral and general health than the Aboriginal and non-Aboriginal adults from the national survey, indicating that national-level data might underestimate the proportion of regional Aboriginal Australians with poor oral health.
