Mental Health After COVID-19 Death-Related Loss in Individuals With Eating Disorders: A Multi-Country Nested Matched...

The COVID-19 pandemic caused millions of deaths worldwide and significantly impacted people with eating disorders, exacerbating symptoms and limiting access to care. This study examined the association between COVID-19 death-related loss-defined as the death of a family member, friend, or acquaintance due to COVID-19-and mental health among people with preexisting eating disorders in the United States (US), the Netherlands, and Sweden.

Participants with a history of eating disorders completed a baseline survey early in the pandemic (US: N = 511; Netherlands: N = 510; Sweden: N = 982) and monthly (US, the Netherlands) or biannual (Sweden) follow-ups from April 2020 to May 2021. The surveys assessed pandemic impact on eating disorder-related behaviors and concerns, anxiety, depression, sleep disturbances, and COVID-19-related deaths. A matched nested case-control design was used to compare individuals experiencing a death-related loss with matched controls.

A substantial proportion experienced a COVID-19 death-related loss (US: 33%; Netherlands: 39%; Sweden: 17%). No significant differences were found between cases and controls on eating disorder, anxiety, depression, or sleep outcomes.

Despite the expected influence of COVID-19 death-related loss on mental health, our study found no significant association. Reactions to pandemics may be highly individual, and practitioners may want to consider broader losses-such as bereavement, missed educational experiences, relationship disruptions, financial instability, and employment challenges-when addressing patients' needs. Future research should continue to explore how death-related loss impacts eating disorder risk and progression.
