Abstract
Australian Aboriginal populations have an extremely high prevalence of lung disease and ear disease. In addition to an improvement in socio-economic conditions, implementation of strategies to address the problem, within the limitations of present conditions, is needed. A 5 month trial was conducted to investigate the effectiveness of a school-based intervention programme involving nose blowing, deep breathing and coughing combined with exercise performed daily. This was a community-based trial, designed to give priority to cultural and ethical considerations, to be non-intrusive and to utilize local skills and resources. Results of the trial showed that signs of upper and lower respiratory tract disease and pulmonary function measurements were statistically significantly improved. Hearing levels showed no statistically significant change. The programme met with a good response from children and teachers. This study does suggest that this strategy may help address the existing problems of lung and ear disease in Aboriginal primary school children, providing some immediate benefits within the limitations of the present socio-economic conditions.
