To examine the risk of sleep problems associated with work stress (job strain, job demands, and decision authority), worries and pain and to investigate the synergistic interaction between these factors and traffic noise.
Sleep problems and predictor variables were assessed in a cross-sectional public health survey with 12,093 respondents. Traffic noise levels were assessed using modelled A-weighted energy equivalent traffic sound levels at the residence. The risk of sleep problems was modelled using multiple logistic regression analysis.
With regard to sleep problems not attributed to any external source (general sleep problems), independent main effects were found for traffic noise (women), decision authority (women), job strain, job demands, suffering from pain or other afflictions, worries about losing the job, experiencing bullying at work, having troubles paying the bills, and having a sick, disabled, or old relative to take care of (women). Significant synergistic effects were found for traffic noise and experiencing bullying at work in women. With regard to sleep problems attributed to traffic noise, strong synergistic interactions were found between traffic noise and, respectively, job demands (men), having pain or other afflictions, taking care of a sick, old, or disabled relative, and having troubles paying the bills. Main effects were found for worries about losing the job, experiencing bullying at work, job strain (men), and decision authority (men). Synergistic interactions could potentially contribute with 10-20% of the sleep problems attributed to traffic noise in the population.
Work stress, pain, and different worries were independently associated with general sleep problems and showed in general no synergistic interaction with traffic noise. In contrast, synergistic effects between traffic noise and psychological factors were found with regard to sleep problems attributed to traffic noise. The synergy may contribute significantly to sleep problems attributed to traffic noise in the population.
研究与工作压力（工作紧张、工作要求和决策自主权）、忧虑和疼痛相关的睡眠问题风险，并探讨这些因素与交通噪声之间的协同相互作用。
在一项横断面公共卫生调查中，对 12093 名受访者进行了睡眠问题和预测变量评估。使用居住处的模拟 A 加权能量等效交通声级评估交通噪声水平。使用多逻辑回归分析模型来评估睡眠问题的风险。
就不属于任何外部来源的睡眠问题（一般睡眠问题）而言，发现交通噪声（女性）、决策自主权（女性）、工作紧张、工作要求、疼痛或其他疾病、担心失业、工作中受到欺凌、支付账单有困难以及有生病、残疾或年老的亲属需要照顾（女性）存在独立的主要影响。在女性中，发现交通噪声与工作中受到欺凌之间存在显著的协同作用。就归因于交通噪声的睡眠问题而言，在男性中，发现交通噪声与工作要求、疼痛或其他疾病、照顾生病、年老或残疾的亲属以及支付账单有困难之间存在强烈的协同交互作用。发现与失业担忧、工作中受到欺凌、工作紧张（男性）和决策自主权（男性）有关的主要影响。协同作用可能会导致归因于交通噪声的睡眠问题增加 10-20%。
工作压力、疼痛和不同的忧虑与一般睡眠问题独立相关，且一般与交通噪声无协同作用。相比之下，在归因于交通噪声的睡眠问题中，发现了交通噪声与心理因素之间的协同作用。这种协同作用可能会对归因于交通噪声的人群睡眠问题产生重大影响。
