"Can physical activity reduce the risk of having tinnitus?".

Objective: Tinnitus, the perception of sound without an external source, affects many adults, impacting quality of life. While factors like hearing loss and psychological distress are linked to tinnitus, the relationship with physical activity remains unclear. This study aimed to explore the association between physical activity, sedentary behaviour, and the presence of tinnitus.

Design: This study is a cross-sectional study. The participants completed the long form of the International Physical Activity Questionnaire. Adjusted logistic regression models were used to investigate associations between (components of) physical activity and the presence of tinnitus, and odds ratios (ORs) were calculated.

Study Sample: This study involved 3004 participants (2751 tinnitus patients, 253 healthy controls).

Results: Engaging in moderate or vigorous-intensity physical activity during leisure time for more than 2.5 hours per week was associated with a reduced risk of having tinnitus (OR = 0.515,  < 0.001). Conversely, individuals who reported sitting for more than 7 hours per day had a significantly higher risk of having tinnitus (OR = 2.366,  < 0.001).

Conclusions: The study suggests a potential protective effect of leisure-time physical activity against tinnitus and highlights the importance of reducing sedentary behaviour. Further research is needed to confirm these findings and to understand underlying mechanisms.
