Abstract

Background and Design.- The purpose of-ttıis study is to investigate the relation between job-si¬te noise and blood pressure. With this purpose we studied worker of the Pendik Kaynarca shipyard for the six months period between September 1994 and February 1995. Female workers, the physically or the mentally handicapped, workers who had complaints of hypertension, and workers whose working period is less than three years we¬re excluded from the study. One hundred twenty seven workers exposed to an environmental noise level of more than 85 dB(A) were the case groups of the study, whereas those 7-5 who were exposed level less than 85 dB(A) comprised the control gro¬up. Data including age, smoking and drinking ha¬bits, education level, body weight and height, fa¬mily history of hypertension and diabetes mellitus were obtained in both groups by a descriptive qu¬estionnaire. In each participant a complete physi¬cal examination was carried out. Results.- The differences among two groups were found to be statistically not significant as to their main characteristics with the exception of their average systolic blood pressure level which was higher in the case group (121.25 ± 16.77 in the case group, 1 1 5.86 ± 14.75 in the control gro¬up, t=2.306, p
