Abstract
OBJECTIVES
The authors hypothesize cardiovascular effects in paper industry workers exposed to noise.
MATERIALS AND METHODS
The study included 72 paper industry workers exposed to noise and two control groups not exposed to noise. The workers completed a questionnaire and underwent a medical examination, measurement of blood pressure, electrocardiogram, blood tests, audiometry and measurement of noise exposure.
RESULTS
The workers exposed to noise, all hearing impaired, were compared with not exposed and showed: significant increase of mean systolic and diastolic blood pressure values (p<0.001), higher frequency of hypertension, systolic and diastolic blood pressure (p<0.01 and p<0.001) and electrocardiografic abnormalities (p<0.05), significant reduction of blood pressure response in orthostatism (p<0.005).
CONCLUSIONS
Our results suggest that for the workers of the paper industry the noise is an occupational risk factor for cardiovascular effects.
