ABSTRACT Shift work is associated with a number of negative health outcomes, although it is not known whether it is associated with sick leave. This systematic review therefore aimed to determine whether an association exists between shift work and sick leave. A systematic literature search was conducted in six databases on observational studies. Two reviewers independently selected relevant articles and appraised methodological quality. Data extraction was performed independently by review couples. Articles were categorised according to shift work characteristics and summarised using a levels of evidence synthesis. In total, the search strategy yielded 1207 references, of which 24 studies met the inclusion criteria. Nine studies were appraised as high quality and used in the levels of evidence synthesis. Two high quality longitudinal studies found a positive association between fixed evening shifts and longer sick leave for female healthcare workers. The evidence was assessed as strong. Evidence was inconclusive for rotating shifts, shift work including nights, for fixed night work, and for 8-hour and 12-hour shifts. The association found between evening work and sick leave in female healthcare workers implies that the association between shift work and sick leave might be schedule and population specific. To study the association further, more high quality studies are necessary that assess and adjust for detailed shift work exposure.

    ABSTRACT: Doctor-certified sick leave differs substantially across sectors, and among health and social workers, in particular, there is an increased risk. Previous studies have shown that work environmental factors contribute to sick leave. Hence, the identification of specific organizational and psychosocial risk factors for long- term sick leave, taking into account potential confounding related to mechanical risk factors such as lifting and awkward body postures, will be of importance in the work of prevention.

    ABSTRACT: We investigated whether fatigue can be used to screen nursing populations for risk of sickness absence. Data were available from a prospective cohort study of 2,059 Norwegian nurses working in hospital care, psychiatric care, and nursing home/home care settings. Physical and mental fatigue were measured at baseline with Chalder's Fatigue Questionnaire (FQ). Self-rated sickness absence at 1-year follow-up was considered high if nurses reported >30 sick days in the past year. Physical fatigue accurately predicted high sickness absence and adequately discriminated between high- and low-risk nurses in nursing home/home care settings. Mental fatigue was not predictive in any setting. The FQ is suitable for screening specific nursing populations for the risk of high sickness absence. © 2013 Wiley Periodicals, Inc. Res Nurs Health.

    ABSTRACT: Background Shift workers are at greater risk than day workers with respect to psychological and physical health, yet little research has linked shift work to increased sickness absence.AimsTo investigate the relationship between shift work and sickness absence while controlling for organ- izational and individual characteristics and shift work attributes that have confounded previous research.Methods The study used archive data collected from three national surveys in Canada, each involving over 20000 employees and 6000 private-sector firms in 14 different occupational groups. The employees reported the number of paid sickness absence days in the past 12 months. Data were analysed using both chi-squared statistics and hierarchical regressions.ResultsContrary to previous research, shift workers took less paid sickness absence than day workers. There were no differences in the length of the sickness absence between both groups or in sickness absence taken by female and male workers whether working days or shifts. Only job tenure, the presence of a union in the workplace and working rotating shifts predicted sickness absence in shift workers. The results were consistent across all three samples.Conclusions In general, shift work does not seem to be linked to increased sickness absence. However, such associations may be true for specific industries. Male and female workers did not differ in the amount of sickness absence taken. Rotating shifts, regardless of industry, predicted sickness absence among shift workers. Consideration should be given to implementing scheduled time off between shift changes.
