The association of social support at work and in private life with sleeping problems in the Finnish health 2000 study.

Objective: To investigate the associations of social support at work and in private life with sleeping problems and use of sleep medication.

Methods: In the nationwide Health 2000 Study, with a cohort of 3430 employees, social support at work and in private life, and sleep-related issues were assessed with self-assessment scales. Purchases of sleep medication over a 3-year period were collected from the nationwide pharmaceutical register of the Social Insurance Institution.

Results: Low social support from supervisor was associated with tiredness (odds ratio [OR] 1.68, 95% confidence interval [CI] = 1.26 to 2.23) and sleeping difficulties within the previous month (OR 1.74, 95% CI = 1.41 to 1.92). Low support from coworkers was associated with tiredness (OR 1.55, 95% CI = 1.41 to 1.92), sleeping difficulties within the previous month (OR 1.77, 95% CI = 1.32 to 2.36), and only among women, with short sleep duration (OR 2.06, 95% CI = 1.22 to 3.47). Low private life support was associated with short sleep duration (OR 1.49, 95% CI = 1.13 to 1.98) and among women, with sleeping difficulties (OR 1.46, 95% CI = 1.08 to 1.33).

Conclusions: Low social support, especially at work, is associated with sleeping-related problems.
