Food Insecurity Among Australian University Students Is Higher and More Severe Across an Extended Period of High Inflation: A Repeated Cross-Sectional Study 2022-2024.

INTRODUCTION

Increasing financial pressures, resulting from a period of high inflation in 2022 and sustained into 2024, may have exacerbated food insecurity among Australian university students. This study aimed to determine the change in prevalence and severity of food insecurity among Australian university students between 2022 and 2024.

METHODS

Repeated cross-sectional, online surveys measured food insecurity using the United States Department of Agriculture Household Food Security Survey Module six-item short form (USDA HFSSM) in addition to six demographic and education characteristics. Students were categorised as being food secure or being marginally, moderately, or severely food insecure. Using a binary variable (food secure vs. food insecure), multivariate logistic regression identified students at higher risk of food insecurity. Independent proportions and logistic regression, adjusting for relevant predictors of food insecurity, measured change in the prevalence of food insecurity between 2022 and 2024.

RESULTS

In 2022 (n = 1249 students) and 2024 (n = 1603), younger, on campus, and international students experienced significantly higher odds of food insecurity. Marginal and moderate food insecurity were unchanged between 2022 and 2024. Severe food insecurity increased from 17% in 2022 to 29% in 2024 (95% CI -0.07, -0.13, p < 0.001), contributing to an overall significant increase in total food insecurity from 42% to 53% (Adjusted Odds Ratio: 1.6; 95% CI: 1.3, 1.8; p < 0.001).

CONCLUSION

This study has identified a high prevalence and worsening severity of food insecurity among Australian university students during a period of high and sustained inflation. SO WHAT?: There is a need for immediate action, including health promotion initiatives and policies to uphold Australian university students' right to food.
