Abstract
Summary: Introduction: Noise exposure is one of the physical hazards in the workplace. Noise has the ability to affect both auditory and non-auditory system. Auditory effects of noise include hearing impairment resulting from excessive noise exposure while non-auditory effects include stress related physiological, behavioral effects, and sleep disturbance. Objective: The objective of this study was to determine the relationship between noise and other risk factors that can affect job stress. Methods: A cross-sectional study was done among 77 workers consisting of 35 workers who were exposed to noise more than 85 dB (A) and 42 workers who were exposed to noise less than 85 dB (A). Workers in the palm oil mills were purposively selected to participate in this study with the inclusive criteria of palm oil mill male worker aged from 15 to 64 years old and the exclusive criteria are worker who diagnosed with psychiatric diseases and have changing in sleeping pattern will not be taken to participated. Questionnaire was administered in determining worker characteristics and O'Donnell Personal Stress Inventory questionnaire was used to determine the stress score among respondents and personal noise monitoring was done using noise dosimeter (model Q 300). Results: Result of descriptive analysis show that the job stress prevalence for workers in high noise conditions was 88.6%. Result of personal noise exposure level indicates that the mean (SD) reading for personal noise exposure level among the exposed group was 90.19 (2.78) while 77.52 (7.47) for the non exposed group. The results of chi square with the value of p<0.05 showed that risk factors such as work shift, noise conditions, use of personal protective equipment and work section had a significant relationship with job stress. Logistic regression analysis, controlling for age, BMI and smoking indicated that factor such as noise exposure level (OR=47.518; 95% CI 11.880-190.064) and work section (OR=20.287; 95% CI = 5.595-73.561) were the important risk factors causing job stress. Conclusion: The findings of this study show that there were two important risk factors that can cause job stress which are noise exposure level and work section. This study found that workers who exposed to noise more than 85 dB (A) will have a tendency to develop stress.
