Temporal Shifts in the Characteristics of Eating Disorder-Related Consultations: A Comparison across the Pre-Pandemic, Earlier-Pandemic-, and Post-Emergency Periods-A Retrospective Study of 4,260 Consultations
This retrospective study of 4,260 consultations across three Japanese hospitals reveals that the COVID-19 pandemic significantly increased eating disorder-related consultations, particularly among adolescents, whose engagement showed a more sustained rise and slower decline compared to the overall trend, likely driven by pandemic-related stress and behavioral restrictions.

Eating disorders are serious conditions where a person's relationship with food, weight, and body shape becomes dangerously distorted. These illnesses are not merely about dieting; they are complex psychological struggles that can lead to severe physical harm and, in the worst cases, death. Because the mind and body are so tightly linked in these conditions, sudden changes in a person's environment can act as a powerful trigger. When daily routines are upended, uncertainty rises, and the sense of control that many people rely on begins to slip, those already vulnerable to eating disorders often find their symptoms intensifying. Understanding how large-scale societal shifts affect these fragile mental states is crucial, not just for treating individuals, but for preparing communities to support them when the next crisis arrives.
In Japan, researchers set out to understand exactly how the global pandemic altered the landscape of eating disorder care. They looked at a massive collection of records from three specialized hospitals that serve as support hubs for people seeking help. Between April 2018 and March 2023, these centers handled 4,260 consultations. The team wanted to see if the arrival of the virus, the subsequent lockdowns, and the eventual easing of restrictions changed who was seeking help, what they were worried about, and how their symptoms presented. They divided the timeline into three distinct eras: the time before the virus arrived, the intense period when emergency restrictions were frequently in place, and the time after those specific emergency measures were lifted. By comparing these periods, they could trace the ripple effects of the pandemic on the people most at risk.
The most striking discovery was a shift in the age of the people walking through the doors. Before the pandemic, the average person seeking help was about 27 and a half years old. During the pandemic, that average dropped significantly to just under 25. This was not a small fluctuation; it represented a clear trend toward younger patients. The data showed that this drop was most dramatic in the first quarter of 2021, right in the middle of Japan's repeated emergency declarations. While the total number of people seeking help eventually began to return to normal levels as restrictions eased, the surge in young people did not fade away as quickly. Specifically, the number of consultations involving teenagers between the ages of 10 and 19 remained stubbornly high long after the overall trend started to decline. This suggests that while the general population may have adapted to the new normal, adolescents continued to struggle with the psychological weight of the crisis for a much longer time.
The nature of the complaints also changed as the pandemic took hold. Before the virus, people seeking help often reported issues like binge eating or vomiting. However, once the emergency measures began, the conversation shifted. There was a marked rise in reports of extreme dietary restriction and an intense fear of being thin. People were talking more about limiting what they ate and less about losing control through overeating. This pattern was even stronger in the group of people who specifically told the doctors that their eating problems had been triggered or made worse by the pandemic. These individuals were, on average, younger than those whose struggles were unrelated to the crisis, and they were far more likely to describe restricting their food intake and feeling a need to be thin. They also reported higher levels of physical restlessness and emotional instability.
The researchers noted that these findings point to a specific vulnerability among adolescents. The stress of staying home, the loss of routine, and the constant uncertainty seem to have had a prolonged effect on how young people managed their emotions and their bodies. While the overall number of consultations eventually began to look like it was returning to pre-pandemic levels, the persistence of high numbers among teenagers indicates that the impact of the crisis was not uniform. The environment created by the pandemic did not just cause a temporary spike in problems; it altered the demographic and clinical profile of the illness for a sustained period. The study concludes that future preparedness must account for this reality. To protect young people from the lasting effects of such large-scale disruptions, society needs to build better systems for early detection and support, ensuring that help is available before a crisis begins, rather than waiting for the damage to become visible.
