Respiratory health in Aboriginal and Torres Strait Islander children in the Australian Capital Territory.
OBJECTIVE
To measure the prevalence of respiratory symptoms and atopic disease in Aboriginal and Torres Strait Islander (indigenous) and non-indigenous children in the Australian Capital Territory (ACT).


METHODS
A two-stage questionnaire survey of children in the ACT with stage two completed for children identified by parents as having respiratory symptoms or asthma in the first stage cross-sectional survey. Participants in the study were: (i) all new entrant primary schoolchildren aged 4-6 years in 1999, 2000 and 2001, 217 being indigenous children and 10 604 being non-indigenous children (80% of eligible); and (ii) Year 1-6 primary schoolchildren in 2000, with 216 being indigenous children and 14 202 being non-indigenous children (52% of eligible). Respiratory symptoms (including recent wheeze and parent-reported asthma) and other factors were measured by parental questionnaire.


RESULTS
Indigenous kindergarten children had more recent wheeze (21%, odds ratio (OR) 1.4 95% confidence interval (CI) 1.0-2.0)) and parent-reported asthma (24%, OR 1.8 95% CI 1.3-2.5) than non-indigenous children (both 15%). However, indigenous children had less eczema (25%, OR 0.7 95% CI 0.5-0.9) and hayfever (14%, OR 0.7 95% CI 0.5-1.0) than non-indigenous children (32% and 19%, respectively). Among children with respiratory symptoms, the symptom severity did not differ between groups, but indigenous children were exposed to more environmental tobacco smoke (ETS) (63%, OR 3.5 95% CI 2.1-5.9) than non-indigenous children (32%).


CONCLUSIONS
Indigenous children in the ACT have more respiratory morbidity but less of the atopic diseases of hayfever and eczema than non-indigenous children. Whether the respiratory morbidity represents 'asthma' or results from increased ETS exposure is unclear and needs to be further explored.
