Older People’s Air Pollution Study (OPAS) – in association with the Social, Economic and Environmental Factors (SEEF) study

Current CAR investigators involved: CIs Jalaludin and Morgan.

The Older People’s Air Pollution Study (OPAS) will investigate associations between current and past exposure to urban ambient air pollutants and health status, quality of life, emergency department visits, hospitalisations and deaths, utilising the resources of the 45 and Up Study. The 45 and Up Study is the largest population-based cohort study in the Southern Hemisphere and has now recruited about 260,000 people aged 45 years and over from the general population in NSW. A unique strength of the 45 and Up Study is linkage to routinely collected health datasets, including hospitalisation, emergency department, death and Medicare datasets. Linking the 45 and Up Study and the Social, Economic and Environmental Factors Study questionnaires to routinely collected datasets, both prospectively and retrospectively, will ensure a uniquely useful cohort to investigate the long- term effects of air pollution in Australia for the first time.
