The study was conducted to analyse possible interactions between noise and shift work, and fatigue as a function of age. In a large questionnaire survey, we assessed personal and environmental risk factors related to fatigue. Noise exposure at work (L(Aeq, 8hr)) was measured with personal noise dosimetry. The sample included 254 day and shift workers, and was divided into 2 age groups (<40- and >40-year-olds). Noise exposure had a main effect on fatigue. The highest noise exposure resulted in an increase in the fatigue level of older shift workers. The quantity of sleep mainly depended on the type of shift and age. Our data suggest that the most important factor generating fatigue could be related to industrial noise exposure, a factor which seems to aggravate work-related fatigue generated in a synergic manner by shift work and ageing. Senior workers should be prevented from cumulating those occupational stressors.
本研究旨在分析噪音与轮班工作之间可能的相互作用，以及疲劳与年龄的关系。在一项大型问卷调查中，我们评估了与疲劳相关的个人和环境风险因素。通过个人噪声剂量计测量工作时的噪声暴露（L(Aeq, 8hr)）。样本包括254名日班和轮班工人，并分为两个年龄组（<40岁和>40岁）。噪声暴露对疲劳有主要影响。最高的噪声暴露导致老年轮班工人的疲劳水平增加。睡眠量主要取决于轮班类型和年龄。我们的数据表明，产生疲劳的最重要因素可能与工业噪声暴露有关，这一因素似乎会加剧由轮班工作和衰老协同产生的与工作相关的疲劳。应防止老年工人累积这些职业压力源。
