To identify latent components from among 13 work and nonwork stressors and to examine whether the accumulation of stress factors within these components was associated with sleep problems.
A cohort of older employees (n = 2771 individuals, n = 3921 person-observations) responded to at least two surveys. Principal Component Analysis (PCA) was used to identify latent components. Analysis of variance was used to examine their associations with sleep.
The components were: "Physical workload and shift work," "Psychosocial workload," "Social and environmental nonwork adversity," and "Life event- and health-related nonwork adversity." They were consistently associated with sleep problems, except for "Physical workload and shift work." "Social and environmental nonwork adversity" was associated with sleep problems at follow-up.
Clusters of work- and nonwork-related stressors were identified, and their accumulation was associated with sleep problems among older employees.
从 13 种工作和非工作压力源中识别潜在成分，并研究这些成分中的压力因素积累是否与睡眠问题相关。
一项针对老年员工的队列研究（n=2771 人，n=3921 人次）至少回应了两次调查。主成分分析（PCA）用于识别潜在成分。方差分析用于研究它们与睡眠的关系。
这些成分分别是：“体力工作负荷和轮班工作”、“心理社会工作负荷”、“社会和环境非工作逆境”以及“与生活事件和健康相关的非工作逆境”。除了“体力工作负荷和轮班工作”外，它们与睡眠问题均存在一致性关联。“社会和环境非工作逆境”与随访时的睡眠问题相关。
识别出了与工作和非工作相关的压力源集群，并且它们的积累与老年员工的睡眠问题相关。
