The aim of the respiratory stream is to determine whether exposure to smoke from the Hazelwood coal mine fire is associated with:
- Respiratory symptoms
- Asthma control
- Decline in lung function
The information collected during the adult survey will be used to identify the ‘sub-cohort’ for the respiratory sub-study. The main comparison will be between those who were heavily exposed to smoke from the Hazelwood coal mine fire and those who were minimally exposed to smoke.
