In a repeated cross-sectional study that examined population-based data from January 2017 through August 2022, ED visits increased by 121% above expected levels, and hospital admissions increased by 54% above expected among patients aged 10-17 years during the pandemic.
“We are hoping this study continues to heighten awareness of the importance of eating disorders, and also to bolster support for eating disorder programs so that we can adequately care for patients and address the increasing demand for treatment and services,” lead author Alene Toulany, MD, adolescent medicine specialist and researcher at the Hospital for Sick Children in Toronto, told this news organization.
The study was published in the Canadian Medical Association Journal.
‘A pressing concern’
The researchers used linked health administrative databases that included all patients in Ontario who were eligible for the Ontario Health Insurance Plan, which is publicly funded. They compared observed and expected rates of ED visits and hospitalizations for eating disorders between a prepandemic period (Jan. 1, 2017, to Feb. 29, 2020) and a pandemic period (Mar. 1, 2020, to Aug. 31, 2022). The researchers examined the following four age categories: adolescents (aged 10-17 years), young adults (aged 18-26 years), adults (aged 27-40 years), and older adults (aged 41-105 years).
Among adolescents, the observed rate of ED visits during the 30 pandemic months studied was 7.38 per 100,000 population, compared with 3.33 per 100,000 before the pandemic (incidence rate ratio [IRR], 2.21).
The rate of ED visits among young adults increased by 13% above the expected rate. It reached 2.79 per 100,000, compared with 2.46 per 100,000 in the prepandemic period (IRR, 1.13).
Among older adults, ED visits increased from 0.11 per 100,000 in the prepandemic period to 0.14 per 100,000 in the pandemic period (IRR, 1.15). The rate of ED visits among adults remained approximately the same.
The rate of hospital admissions among adolescents increased by 54% above the expected rate during the pandemic. The observed rate of hospital admissions before the pandemic was 5.74 per 100,000, vs. 8.82 per 100,000 during the pandemic (IRR, 1.54). Hospital admissions remained stable or decreased for the other age groups.
“Eating disorders have increased globally in children and adolescents during COVID,” said Dr. Toulany. “There are a number of risk factors contributing to this pandemic rise, including isolation, more time on social media, decreased access to care (as many in-person services were not available due to the pandemic), as well as fear of getting infected. All of these could contribute to an increased risk of developing an eating disorder or of making an existing one worse.”
Regardless of the cause, more investment in eating disorders research and eating disorder programs for adolescents and adults is needed, she said.
“The pandemic served as a catalyst, because it started to shed light on the prevalence of eating disorders, especially in young people. But it’s very important that we recognize that this has been a long-standing issue and a pressing concern that has been consistently overlooked and underfunded,” said Dr. Toulany.
