<p><em>Objectives</em>: With workforces in industrialised countries getting older, the study examined how shiftworking affects sleep in later life.</p><p><em>Method</em>: Longitudinal data were collected in 1996, 2001 and 2006 from a large sample of employees who were 32, 42, 52, and 62 years old in 1996.</p><p><em>Results</em>: Effects of shiftwork were most apparent in middle aged participants, becoming less apparent in later years when people tended to leave shiftwork. However, a group of younger former shiftworkers reported more sleep problems than those who had never worked shifts. Giving up shiftwork off-set a trend for sleep problems to accumulate over time, with the net result of no change in sleep problems following cessation of shiftwork.</p><p><em>Conclusions</em>: Poor sleep quality is a temporary consequence of shiftwork for some, while for others it is a cause of shiftwork intolerance.</p>
This was one of the few published longitudinal studies to examine whether the effects of shiftwork on sleep persist after exiting shiftwork. Uniquely, it examined sleep complaints from different age cohorts and distinguished between former and current shiftworkers, and workers who had never worked shifts.
