Abstract
Objective/Background: To examine the prospective association between work-related mental fatigue and risk of insomnia symptoms, and if leisure time physical activity modifies this association.

Participants: A total of 8,464 women and 7,480 men who participated in two consecutive surveys of the Norwegian HUNT study.

Methods: The study comprises longitudinal data on persons who were vocationally active and without insomnia symptoms at baseline in 1995–1997. We used a modified Poisson regression model to calculate adjusted risk ratios (RRs) with a 95% confidence interval (CI) for insomnia symptoms at follow-up in 2006–2008 associated with work-related mental fatigue and leisure time physical activity at baseline.

Results: Women and men who always experienced mental fatigue after a workday had RRs of insomnia symptoms of 2.55 (95% CI 1.91–3.40) and 2.61 (95% CI 1.80–3.78), respectively, compared to workers who never or seldom had this experience. There was no strong modifying effect of leisure time physical activity on this association, but workers who always experienced mental fatigue had a RR of insomnia symptoms of 3.17 (95% CI 2.28–4.40) if they reported low physical activity and a RR of 2.52 (95% 1.89–3.39) if they reported high physical activity.

Conclusion: This study shows that work-related mental fatigue, caused by high cognitive workload, is a strong risk factor for insomnia symptoms. There was no clear modifying effect of leisure time physical activity but workers who experienced excessive work-related fatigue accompanied by low physical activity had the highest risk of insomnia symptoms.
