Effects of age, working hours, and job content on sleep: a pilot study.
The effects of age, shiftwork with changing schedules, and job stress on self-reported sleep quality were studied in 2767 wage earners aged 32, 42, and 52, by means of a questionnaire. Greater age was associated with poorer sleep quality, as was shiftwork for the 32- and 42-year-olds but not for the 52-year-olds, suggesting a selection effect between the ages of 42 and 52. More than specific job demands, it was perceived job difficulty that was related to sleep dissatisfaction. No interactions between age, shiftwork, and job characteristics were found.
