Sickness absence has increased from 1993 to 2003. Much of the increased is attributed stress at work and in society, but also the labor market situation and attitude changes. There is, however, new research that suggests that much of the perception of feeling ill is associated with fatigue and that disturbed sleep may be part of the explanation. Previous research has been very scant. The present project will investigate the prevalence of fatigue and disturbed sleep among those on long-term sick leave and their prediction of new cases and return to work. Here will be analyzed the level-of-living surveys (ULF - 50.000 individuals) and the Work environment survey (AMU - 7000 individuals). The two complement each other. In both, the prevalence of fatigue and disturbed sleep will be described, as well as the development across the recent 15 years. In addition the development of stress, physical work load and other variables will be investigated. Fatigue and disturbed sleep will also be used as pr redictors of future long-term sick leave based on register data from the National health insurance board. On prospective study will be carried using longitudinal registers of the WOLF study which has detailed data on sleep for 5700 individuals at two points in time. All analyses use logisitic regression and are made separately for women and men. The results are expected to be of considerable use for knowlege of the role of fatigue and disturbed sleep ifor long-term sick leave and flor prevention and rehabilitation.
