Abstract: (590 Views)
Background and Objectives: Numerous factors including job type and conditions, work organization and individual characteristics affect work ability of the workers. Further, occupational stress is not solely influenced by individual characteristics; a stressful work environment is also a significant source of stress. Noise has been recognized as one of the major occupational hazards that adversely impacts work condition in many industries. In this study, the association between noise exposure and occupational stress and work ability of the workers in a food processing plant was investigated.
Methods: This descriptive-analytic study was performed with participation of 142 workers of the food processing plant in various work groups. OSIPOW questionnaire results were utilized to measure occupational stress while work ability of the workers was determined by Work Ability Index (WAI) questionnaire. Noise exposure of the workers was calculated as a measure of 8-hour time weighted average. The association between noise exposure and work ability was analyzed using Pearson and Spearman correlation tests. Multiple regression test was utilized to analyze the simultaneous effect of variables, while to analyze the mean difference of independent variables, one-way analysis of variance (one-way ANOVA) was used.
Results: The results of the study demonstrated a significant positive association between noise exposure and stress level across various work groups (p<0.001). Furthermore, a significant negative relationship can be found between noise exposure and work ability of the workers (p<0.001). A simultaneous analysis of variables influencing occupational stress and WAI demonstrated that noise had the largest effect. While occupational stress levels were not significantly different across working groups, mean difference of WAI was rather significant among them.
Conclusion: This study demonstrated that higher levels of noise exposure may contribute to increased occupational stress and decreased work ability among workers.
