Asthma is the most common chronic childhood disease affecting up to one in four NZ children. Significant ethnic disparities exist for Maori in asthma related illness, with Maori children twice as likely to be hospitalised as non-Maori. The ways in which schools support a child with asthma can have a significant impact on their overall asthma control and affect the child’s ability to learn. Strategies to improve asthma management in NZ schools have not been investigated and no national policy exists to guide schools. Under a Kaupapa Maori methodology, and in partnership with Maori community providers and governmental agencies, we will assess a Maori-centred, school-based asthma intervention to improve outcomes for children with asthma. This will result in the development of an evidence-based, asthma toolkit for primary schools which will reduce asthma disparities, inform health-education policy, and act as a template for the management of other chronic conditions in schools.
