L’objectif de cette étude était d’identifier des composantes latentes parmi 13 facteurs de stress professionnels et non professionnels et examiner si l’accumulation de facteurs de stress dans ces composantes était associée à des problèmes de sommeil.
Objective: To identify latent components from among 13 work and non-work stressors and to examine whether the accumulation of stress factors within these components was associated with sleep problems. Methods: 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. Results: The components were: ‘Physical workload and shift work’, ‘Psychosocial workload’, ‘Social and environmental non-work adversity’ and ‘Life event- and health-related non-work adversity’. They were consistently associated with sleep problems, except for ‘Physical workload and shift work’. ‘Social and environmental non-work adversity’ was associated with sleep problems at follow-up. Conclusions: Clusters of work- and non-work-related stressors were identified, and their accumulation was associated with sleep problems among older employees.
