Abstract The aim of this study was to investigate self-reported health effects of extended work hours (10 h on, 14 h off, 21 days' work, 21 days off) for 40 male tunnel workers in an Arctic area. Questionnaires on demographics and subjective health complaints (SHC), including musculoskeletal, pseudoneurological, gastrointestinal, allergic and flu-like complaints the last thirty days were distributed on day 14 of a work period. The questionnaires also included items on coping, psychological job demands, control, and social support. The questionnaire was repeated three times during a nine-month 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 consisting of a cross-section of the Norwegian working population assessed in an earlier study. 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 associations between this type of long work hours and changes in self-reported health were found.
