As part of the delivery, I have been asked to facilitate for this project to deliver a co-created field-based epidemiological study in two contrasting sites in Kenya – Mukuru and Buruburu – that will characterise the clinical characteristics and lung function of children aged 5-18 years.  This will be accomplished through the use of participatory techniques to contribute to study design and explore community knowledge about what damages lungs and the lived experience of air pollution and lung health.
