The effects of diet and physical activity induced weight loss on the severity of tinnitus and quality of life: A randomized controlled trial.

Background & Aims: Subjective tinnitus is the most common and manifest auditory symptom of an existing pathology in the auditory system. Although the effect of obesity on tinnitus is still uncertain, it is known that increased fat tissue increases the severity and symptoms of tinnitus. In this study, it was aimed to evaluate the effect of weight loss through diet and physical activity on tinnitus.
Methods: Forty-six obese subjects diagnosed with tinnitus were randomized into the diet + physical activity (PA) (n = 13), diet (n = 16) and the control groups (n = 17). The anthropometric measurements, tinnitus severity scores, tinnitus handicap inventory (THI) scores and short form quality of life (SF-36) scores of the individuals were recorded and compared at the beginning and at the end of the study.
Results: In the diet + PA and diet groups; body weight (diet + PA:-6.5 ± 2.6; diet: -4.1 ± 1) tinnitus severity (diet + PA:-11.0 ± 7.0; diet: -9.0 ± 8.7) and THI scores (diet + FA:-15.0 ± 9.5; diet: -14.0 ± 10.0) significantly decreased compared to the control group (p < 0.01). This decline was more in those with weight loss of ≥5.0% than those with <5.0%. SF-36 score was significantly increased in the diet + PA and diet groups (respectively 10.0 ± 5.5 and 6.0 ± 2.7) compared to the control group (p < 0.05).
Conclusions: Diet and physical activity intervention ameliorated the tinnitus severity and quality of life in obese patients with tinnitus. However to generalize this findings further studies are needed. REGISTERED UNDER CLINICALTRIALS.
