Socioeconomic status and adherence to COVID-19 preventative measures in Australia: A national cohort study.

Abstract

The uptake of recommended preventative measures is a critical concern for protecting the public against COVID-19 outbreaks and future pandemics. However, it is unclear to what extent COVID-19 preventative measures were followed in Australia. This study aims to determine adherence level to COVID-19 preventative measures in 2021, and whether these were associated with socioeconomic status (SES). This was a national cross-sectional study using data from the Household Income and Labour Dynamics in Australia (HILDA) survey. This study included 15 457 community-dwelling adults (18 years or older) who participated in the 2021 wave of HILDA survey. SES was assessed by the Socio-Economic Index For Areas (SEIFA) score, split into quintiles. Outcomes included self-reported adherence to COVID-19 preventative measures (mask wearing, keeping distance, staying home; sum score range 3-15) and COVID-19 status (yes/no). Linear and logistic regression were used accordingly to assess the association between SES and the sum score of adherence to COVID-19 measures, and COVID-19 vaccination status. Adherence to COVID-19 preventative measures and uptake of COVID-19 vaccine in Australia in 2021 were moderate (between 60% and 70%). Regression models showed higher SES was associated with a slightly higher score of adherence (β = .08, 95% CI = .04-.12) and a higher likelihood of self-reporting receiving COVID-19 vaccination (OR 1.27, 95% CI = 1.23-1.31). SES was positively associated with the level of adherence to COVID-19 preventative measures and the probability of receiving COVID-19 vaccine. The findings of this study highlight the potential benefits of considering SES, particularly its impact on equity and access, when designing an educational program or awareness campaign in times of crisis. SO WHAT?: The findings of this study highlight the importance of considering SES when designing an educational program or an awareness campaign in times of crisis.
