Respiratory function in Aboriginal children

Abstract
One hundred and fifty-one Aboriginal school children and 246 non-Aboriginal children, all aged between 11 and 15 years, performed lung function tests with a Vitalograph spirometer. The results showed that the mean forced vital capacity was 20% larger in non-Aboriginal children of both sexes. Similar differences were found for the one-second forced expiratory volume, which was 15% larger for the non-Aboriginal boys and 17% larger for the non-Aboriginal girls. Comment is made on their smoking practices.
