Vitamin D status and shift workDavies, Luke (University of Chester, 2013-09)In the UK, there has long been a need for consuming foods high in vitamin D in order to prevent diseases associated with low bone mineral density such as osteoporosis in adults and rickets in children. It has been claimed that potentially, 50% of the UK adult population are vitamin D insufficient in winter and spring time, actual deficiency may be 16%. Those workers who commence their working hours in the evening may be deprived of vitamin D synthesising UVB. Moreover, the physical maladaption to altered circadian rhythms experienced by many shift and, particularly, night workers has been identified as a leading cause of change to dietary intake. The previous literature has documented associations between nocturnal working schedules and adverse health effects. The influence of working place shift schedules i.e. night and day shifts, on vitamin D status has not been researched extensively.
