The COVID pandemic began in Australia in March 2020. This project was developed thanks o a NSW Health grant. 32,000 participants from the 45 and Up Study completed five surveys from 2020 to March 2022. The aim of the COVID Insights was to understand the impacts of COVID-19 and COVID-19 prevention strategies on the health, wellbeing and behaviors of a diverse group of older Australians. Understanding this provided evidence to inform policies and practices that support all Australians. The sub-study investigated: • the level of understanding of messages about COVID-19 prevention • the impact of COVID-19 prevention measures on health and wellbeing, preventive health activities, health services use, behaviours and experiences • the influence of demographics, health status and social variables on health outcomes during the COVID-19 pandemic • the accessibility of health services during the COVID-19 pandemic.
