How does tinnitus change over time? – new study
Friday 18 December, 2020New research, using data from the UK Biobank, has revealed important information about the natural history of tinnitus, how it changes over time and its risk factors.
The study was led by Dr Piers Dawes from the University of Manchester with support from the British Tinnitus Association. The study looked at data from 168,348 people, with 4,746 assessed at a four-year follow-up.
Published in the journal BMJ Open, the research found that almost one-fifth of middle-aged people have permanent tinnitus and around one-third of these describe it as ‘bothersome’. This is a much higher proportion of people than in other age groups: tinnitus affects an estimated one in eight adults in the UK.
Over time, 18.3% of people reported that they no longer had tinnitus. 9% reported an improvement, 9% said that it was more bothersome and the rest reported no change.
Dr Dawes commented: “This is an important study because it is based on a very large and diverse sample of UK adults and is one of very few to give information about people’s long-term experiences of tinnitus. The study shows that tinnitus is persistent for most people. So it is really important to focus on preventing tinnitus in the first instance, and then on effective management of symptoms in people living with tinnitus.”
The study also found that whilst men were more likely to experience tinnitus, women were more likely to report it as bothersome, as were hearing aid users and people on a low income.
The authors identified that the main controllable risk factor for tinnitus is exposure to noise at work. Other risk factors included age, hearing difficulties, ototoxic medication and neuroticism.
David Stockdale, Chief Executive of the British Tinnitus Association and a co-author of the study, said: “This paper shows how the use of existing bioresources can advance our knowledge of tinnitus. It’s vital that these are better utilised, as the data contained could reveal crucial information to help our progress towards a cure for tinnitus.”
