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.
