Abstract
BACKGROUND: Noise can cause serious health problems. Regular use of personal health equipments can reduce such problems. This study has been designed to compare the blood pressure of tire manufacturing workers, who were exposed to noise (> 85 db) and used personal health equipment, with a control group without noise exposure.
   METHODS: In this case-control study, 70 workers who were exposed to noise (case group) and 220 workers who were not (control group) were recruited. Regular use of personal health equipment was compulsory. LEQ was calculated for both groups. To analyse the data, chi-square test and t-test were implemented. Finally multivariate regression model was developed.
   RESULTS: No difference was seen between the groups in terms of basic characteristics (age, years of working, and BMI). Mean systolic blood pressure in case and control groups was 116.6 and 117.5, respectively; giving a P-value of 0.50. Mean diastolic blood pressure in case and control groups was 76.7 and 77.4, respectively; giving a P-value of 0.47. Results indicate no significant difference between blood pressure of cases and control groups.
   CONCLUSION: We did not see any significant difference between the blood pressure of those exposed to noise, and regularly using personal health equipment, and those in the control group without noise exposure. Therefore, we strongly recommend use of such equipments.
