Background and Aims:

Both insomnia and sleep duration have previously been linked with a range of adverse outcomes, but no studies have explored their relative effect on subsequent work disability. The aim of the present study was to investigate the contribution of insomnia and sleep duration to later short and long-term work disability.

Methods:

Data on insomnia, sleep duration and potential confounders were gathered from 7849 working persons (40-44 years). The outcome was award of disability pension 18-48 months later, as registered in the National Insurance Administration.

Results:

Insomnia was a strong predictor of both short- and long-term work disability, and this effect remained significant in the fully adjustment model. Reduced or excessive sleep duration was significantly associated with subsequent work disability in the fully adjusted model; only in the crude model did sleeping less than 5.5 hours predict work disability.

Conclusions:

The present study provides further evidence that insomnia is a strong and independent risk factor work subsequent work disability, while at the same time ruling out that this association is caused by a reduced or excessive sleep duration.
