Title Work organisation and unintentional sleep: Results of the WOLF study
Bibliographic information Sep. 2002, Vol.59, No.9, p.595-600. 55 ref.
Abstract Falling asleep at work is receiving increasing attention as a cause of work accidents. This study investigates which variables (related to work, lifestyle, or background) are related to the tendency to fall asleep unintentionally, either during work hours, or during leisure time. 5589 individuals responded to a questionnaire, and a multiple logistic regression analysis of the cross-sectional data was used to estimate the risk of falling asleep. The prevalence for falling asleep unintentionally at least once a month was 7.0% during work hours and 23.1% during leisure time. The risk of unintentional sleep at work was related to disturbed sleep, shift work, and higher socioeconomic group. Being older, a woman and a smoker were associated with a reduced risk of unintentionally falling asleep at work. Work demands, decision latitude at work, physical load, sedentary work, solitary work, extra work, and overtime work were not related to falling asleep at work. With respect to falling asleep during leisure time, disturbed sleep, snoring, high work demands, being a smoker, not exercising, and higher age (>45 years) became risk indicators.
