Summary
Shift work disrupts the internal body clock, which increases the risk for obesity and type 2 diabetes. Our research demonstrates meal timing plays an important role in this metabolic disturbance. Data from animal studies suggests that the adverse consequences of shift work can be reduced by eating only during the day. This study will investigate if this also occurs in humans, potentially leading to a straightforward solution to reduce the burden of chronic diseases in shift workers.

Summary
Sleep disruption and circadian rhythm disturbances are emerging as a significant public health issue for all shift workers. The objective of this study is to further define and understand the effects of disrupted sleep rhythms specifically during pregnancy on the mother’s metabolism and the long term impact on the metabolic health of her offspring. The long term aim is to use the research outcomes to develop strategies for prevention of the harm to mother and child.
Circadian Mechanisms For Sex Differences In Shift Work Tolerance

Summary
It is well-established that women respond more poorly than men to shift work schedules, having more health complaints, more drowsiness and more accidents at work than men. The physiological cause of this sex difference is not known. Our research suggests that differences in the circadian rhythms of women and men may promote shift work intolerance in women. This study is designed to examine sex differences in the effect of office-level light on the biological clock during a simulated night shift.
Circadian Rhythm Disruption And Metabolic Function

Summary
Shiftwork is an under-researched risk factor for obesity and diabetes. Because shiftwork disrupts hormonal and sleep rhythmicity, eating patterns and light exposure, abnormal rhythmicity may be a causal factor in metabolic disease. Direct evidence for the link is lacking and the underlying mechanisms responsible are unknown. This project aims to understand how shiftwork may lead to diabetes and obesity, knowledge essential for the design and testing of potential interventions.
