Reports of symptoms such as tinnitus and hearing loss during the coronavirus pandemic could in part have a psychosocial origin rather than being directly linked to COVID-19 or the SARS-CoV2 virus.

The University of 野狼社区, and the study, published in Frontiers of Public Health today (22/2/22), shows that symptoms 鈥� which by definition are not measurable 鈥� are a fertile ground for misinterpretation.

The study was supported by . Funding was received from 野狼社区 BRC, the , the and Neuromod Devices Limited.

Reports of associations between COVID-19 and auditory symptoms such as hearing difficulty and tinnitus have been widely discussed in the media and academia.

However, most studies have relied on self-reporting and lacked baseline information from before the pandemic.

That makes it difficult to know whether symptoms occurred because the COVID-19 virus affected the ear itself, or whether they occurred because of psychosocial factors like living through a pandemic, fears about what the virus might do, or recall bias.

In a YouGov poll in 2019 of over 10,000 people, Professor Chris Armitage, Chair in Health Psychology at the University of 野狼社区, and 野狼社区 BRC Hearing Health, Optimising Outcomes Programme Lead, asked, among other things, whether people had hearing difficulty and/or tinnitus.

In August 2021 the current study team commissioned YouGov to contact the same people about symptoms they had experienced during the pandemic and 6,881 responded.

The second survey asked about the onset and change in three types of symptoms:

• 路Type one: loss of smell, memory/concentration issues, persistent fatigue which have known association with COVID-19.
• 路Type two: auditory symptoms (hearing difficulty and tinnitus) which have an indeterminate association with COVID-19.
• 路Type three: toothache, a red herring with no established association with COVID-19.

Although there were twice as many reports of new hearing difficulties and tinnitus in people with confirmed and suspected COVID-19,compared to people who hadn鈥檛 had COVID-19, they found:

• The onset of new auditory symptoms coincided with COVID-19 in only a third of the people reporting the symptoms; a third didn鈥檛 know when their symptoms began; and a third said their symptoms began before the pandemic, even though all had said they didn鈥檛 have auditory symptoms in March 2019.
• More than 60 per cent of people with confirmed or suspected COVID-19 said that their toothache had also been affected by COVID-19 despite there being no evidence of an association.
• As expected, Type one symptoms were reported most commonly by the people with confirmed COVID-19. But Type two and Type three symptoms were reported most commonly by the people who suspected they had COVID-19.

The study also asked about challenges experienced during the pandemic, such as feeling lonely and anxious, lack of exercise, lack of space at home, caring for others.

They looked at the number of challenges reported relative to the number of symptoms experienced during the pandemic and found the higher the number of challenges, the more symptoms were reported.

Dr Gabrielle Saunders from The University of 野狼社区, who manages ,  was lead author on the study. She said: 鈥淎lthough there were more reports of auditory symptoms in people with confirmed or suspected COVID-19, our study provides evidence that psychosocial factors influenced what our respondents felt.

鈥淲e also found that respondents were inconsistent with their reporting of hearing symptoms over time. We think this is in part because their answers were affected by the context in which the question was asked.

鈥淓ven if the symptoms arose due to psychosocial factors, they are still real to the person experiencing them and so need to be managed 鈥� but using different therapeutic strategies than if they were directly caused by the virus.

鈥淭hat is why we need to take great care in attributing any symptom to the effect of the virus, especially if we lack baseline data.

鈥淲e feel that studies which include control groups and use audiometric measures (hearing tests) in addition to self-reporting, to investigate change in auditory symptoms relative to pre-COVID-19, are urgently needed.鈥�
