Do Body Mass Index Levels Correlate with Tinnitus Among Teachers?

 Working conditions can contribute to the development of lifestyle-related diseases among teachers, including obesity and tinnitus. Describing tinnitus in relation to characteristics and comorbidities can help the treatment and prognosis of teachers affected by this symptom.  To verify a possible association between tinnitus complaint and body mass index (BMI) in teachers.  Cross-sectional study with a sample of teachers who responded to the Visual Analog Scale (VAS) and to the Tinnitus Handicap Inventory (THI). The BMI (kg/m2) was calculated based on self-reported body weight (in kilograms) divided by height (in meters squared). Nonparametric statistics were applied adopting a significance level < 0.05  A total of 83 teachers were assessed, with a mean age 48 ± 9.7 years old; 63.9% ( = 53) were females; 44.6% were eutrophic (  = 37), and 16.9% ( = 14) were obese. Of the total, 19.3% (  = 16) reported tinnitus. No differences were found between the groups and BMI (  > 0.05), although there was a significant difference between the Tinnitus and No Tinnitus groups for age (  < 0.001). The chi-squared test showed an association between age group and tinnitus (  < 0.028); those with tinnitus were in the 49 to 65 years old age group. In addition, there was a moderate correlation between tinnitus parameters (VAS; THI-Functional; THI-Total) and BMI.  There was a moderate correlation between tinnitus parameters and BMI indicating that, as the BMI increased, so did the impact of tinnitus in the lives of the teachers. Body mass index should be considered a factor in tinnitus assessment and rehabilitation process.
