The impacts of COVID-19 on eating disorders and disordered eating: A mixed studies systematic review and implications for healthcare professionals, carers, and self
Objective: The unique constraints to everyday life brought about by the COVID-19 pandemic have been shown to negatively impact those with pre-existing mental health issues such as eating disorders. While individuals with eating disorders or disordered eating behaviours represent a vulnerable group to COVID-19 pandemic, the impact of the pandemic is yet to be fully established. As such, we systematically examined the impact of the COVID-19 pandemic on eating disorders and disordered eating behaviours. Method: We searched electronic databases MEDLINE, PsycINFO, CINAHL, and EMBASE for literature published until October 2021. Eligible studies were required to report on individuals with or without a diagnosed eating disorder or disordered eating behaviours who were exposed to the COVID-19 pandemic. Results: Seventy-two studies met eligibility criteria with the majority supporting an increase in eating disorder or disordered eating behaviours associated with the COVID-19 pandemic. Specifically, children and adolescents and individuals with a diagnosed eating disorder present a vulnerable group to the impacts of the COVID-19 pandemic. Discussion: This systematic review provides a timely insight into COVID-19 eating disorder literature and will assist in understanding possible future long-term impacts of the pandemic on eating disorders behaviours. It appears that the role of stress in the development and maintenance of eating disorders was intensified as a means to cope with the uncertainty of the pandemic. Future research is needed among understudied and minority groups and to examine the long-term implications of the COVID-19 pandemic on eating disorders and disordered eating behaviours.
