Still healthy after extended work hours? Ten hours shift, twenty-one days working period for tunnel workers.
The aim of this study was to investigate self-reported health effects of extended work hours (10 h on/14 h off) for 21 d at work/21 d off, for 40 male tunnel workers in an Arctic area. A questionnaire obtaining information about demographics and subjective health complaints (SHC), including musculoskeletal, pseudoneurological, gastrointestinal, allergic, and flu-like complaints the last thirty days was distributed on day 14 of a work period. In addition questions on coping, psychological job demands, control, and social support were asked. The questionnaire was repeated three times during a nine months observation period. Twenty-six workers completed all three questionnaires. The prevalence of subjective health complaints did not change during the observation period. The prevalence of subjective health complaints was the same or lower than in a control group. There was a slight increase in self-reported job demands during the observation period. Coping, job control, and social support from colleagues and management were reported high and did not change. No association between this type of long work hours and changes in self-reported health was found in this study. However, this might have been a selected group of workers, and the same results may not be found in another population.
