Objective: To verify whether the occupational hazards in the rotogravure industry can be associated with cardiovascular effects.
Methods: We evaluated cardiovascular parameters and audiometric tests and analyzed noise, solvents, and shift work in 44 exposed and 44 unexposed workers.
Results: Unlike unexposed workers, the rotogravure workers showed significant increase of mean systolic and diastolic blood pressure (BP) values (P = 0.019; P = 0.003), higher frequency of hypertension (P = 0.002) and electrocardiographic abnormalities (P = 0.0001), significant reduction or no variation of BP response to orthostatism (P = 0.0001), and association between high levels of noise and diastolic blood pressure (P = 0.0067). Subjects with hearing loss showed high frequency of hypertension and a reduction or no variation of BP response to orthostatism (both P = 0.05).
Conclusions: Data obtained suggest that these are the effects on the cardiovascular system of rotogravure workers who are exposed to noise.
