Anxiety and stress over COVID-19 pandemic associated with increased eating.

Objective: Stressful experiences can dramatically affect eating. The relatively sudden, global emergence of the COVID-19 pandemic served as a massive stressor to virtually all people, regardless of infection status. This study hypothesized that actual and perceived stressors from the onset of the COVID-19 pandemic, in the categories of recurring disruptions, environmental threat, and social isolation would be positively associated with increased self-reported eating in the United States. Methods: Over 1100 English-fluent adults (52.8% women) living in the United States were recruited for a cross-sectional online survey about eating, COVID-19 consequences, and stress experiences. Linear regressions examined associations between perceived stress on five eating measures, and individual differences in personal/work situations, perceptions, and adverse experiences during the pandemic. Results: Anxiety, worry, and stress over, rather than direct consequences of, COVID-19 were most consistently associated with self-reported increased eating. Largely, these fell into the stressor categories of environmental threat and social isolation, not recurring disruptions. Body mass index and current self-reported eating pathology symptoms were also consistently associated with these outcomes. Conclusions: These correlational findings suggest specific stressors have pronounced influences on eating behavior of US adults. Remotely deliverable stress mitigation strategies should be explored to attenuate increased eating.
