In the past two years, COVID-19 has provoked anxiety throughout the world for people worried they and their loved ones would get the virus and suffer tragic consequences. Two new studies in Annals of Allergy, Asthma and Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI), showed the different effects of COVID-19 on anxiety. In those with asthma, the pandemic was associated with increased anxiety and asthma symptoms, while in parents of children with food allergies the pandemic led to decreased food allergy-related anxiety.

The first study examined whether COVID-19-related anxiety was associated with uncontrolled asthma in adults.

We gathered 873 online surveys from adults diagnosed with asthma to gauge their anxiety and asthma control during the pandemic. Almost 57% had a self-reported asthma attack during the pandemic, 29% contacted their healthcare provider for urgent symptoms and 43% had uncontrolled asthma. Almost 48% of participants had a high anxiety score, and participants with higher anxiety levels were more likely to report having uncontrolled asthma.”

“Findings from a national sample of US adults suggest increased physical and mental symptoms among those with chronic respiratory conditions during COVID-19 compared to others,” said allergist Jon Romeo, DO, chair of the ACAAI Asthma Committee. “This study seems to support these findings and also shows a significant, unfavorable effect of COVID-19-related anxiety on asthma control.” Dr. Romeo was not involved with the study.

The second study examined 293 questionnaires completed by Canadian parents of children with food allergies. The survey was conducted in May and June of 2020, at the beginning of the pandemic when in-person medical visits for non-urgent care were limited, and most schools had transitioned to a virtual model.

“Through the questionnaire, we examined food allergy-specific anxiety (FAA), which is distinct from other types of anxiety,” said allergist Edmond Chan, MD, ACAAI member and an author of the study. “67% of the respondents reported an increase in stress and anxiety that they attributed to COVID-19, while only 28% reported increased FAA due to COVID-19. In fact, most respondents reported unchanged (30%) or decreased (42%) FAA attributable to COVID-19.”

Respondents in the survey reported that the pandemic was associated with a decrease in all FAA aspects, with the greatest reductions related to worries about unfamiliar places and management of allergy reactions by other caregivers. As one respondent wrote, “It’s been easier during quarantine because we are not going out to eat, not going to parties…not going to school or anywhere that used to cause anxiety about potential accidental allergen exposure.” Some respondents noted increased anxiety due to the pandemic causing shortages of safe foods and ingredients they rely on to prevent allergic reactions for their children.

Both studies noted a limitation in their sample regarding a lack of ethnic and economic diversity; both had a higher proportion of educated, white females responding.
