Food Insecurity Is Associated with Depression, Anxiety, and Stress: Evidence from the Early Days of the COVID-19 Pandemic in the United States

Purpose: To understand associations between food insecurity and depression, anxiety, and stress during the COVID-19 pandemic among low-income adults in the United States. Methods: During March 19–24, 2020, we fielded a national, web-based survey (53% response rate) among low-income adults (<250% of the federal poverty line) in the United States (N=1,476). Food security status was measured using the 18-question USDA Household Food Security Module. Multivariable-adjusted logistic regression models examined the association between food insecurity and psychological distress outcomes and COVID-19-specific worries. Qualitative data from an open-response question were also analyzed. Results: More than one-third of low-income adults screened positive for depression (33%), anxiety (39%), and high stress (39%). Greater food insecurity was associated with a dose–response relationship with all psychological distress outcomes (all outcomes p-trend <0.001) and COVID-19-specific worries (all outcomes p-trend <0.001). Compared to food-secure adults, adults with very low food security were more likely to screen positive for depression (odds ratio [OR] 7.72; 95% confidence interval [CI]: 5.52–10.80), anxiety (OR 6.19; 95% CI: 4.51–8.51), and high perceived stress (OR 10.91; 95% CI: 7.78–15.30). Very low food security was also associated with increased worries about the effect of COVID-19 on one's health (OR 2.56; 95% CI: 1.90–3.45), income (OR 5.18; 95% CI: 3.78–7.06), and ability to feed one's family (OR 9.24; 95% CI: 6.61–12.92). Conclusions: The COVID-19 pandemic is negatively associated with the mental health of low-income adults in the United States, with disproportionate associations among adults experiencing food insecurity. These disparities have the potential to increase mental health disparities over the long term.
