ABSTRACT

Objective: To analyze otic barotrauma (OBT) from the occupational and epidemiological point of view in a professional divers cohort. Material and methods: In a 298 scuba-diver fixed cohort hired at fishing cooperatives at Guerrero Negro, Baja California Sur state in Mexico, 56 divers with OBT diagnosed with occupational illness in a 5-year period were identified. In all, we explored body mass index (BMI), addiction acquired at work, number and immersion depth, upper respiratory tract infections, high blood pressure, diabetes mellitus, and asthma backgrounds. Analysis included prevalence point (PP) calculation, density incidence (DI), cumulative incidence ratio (CIR), odds ratio (OR) with CI 95 %, in explored variables; Mantel-Haenszel test was applied. Results: PP: 0.008 or 0.8 %; DI = 0.40 persons/years; CIR = 0.231; BMI ‹ 23 or ›27, OR = 11.63 (4.57-31.43), p ‹ 0.0001; addictions, OR = 1.95 (0.89-4.37), p = 0.07; number and depth of immersions = › 10 m and more than 4 times by workday, OR = 3.24 (1.53-7.01), p = 0.0007; upper respiratory tract infections: 1.42 (0.64-3.21), p = 0.35. Conclusions: Although PP is apparently low, velocity of OBT installation as a professional illness in these divers is relatively high as soon as they begin their life work, based on person time rate and high probability for illness.
