Our study examines the relationships between work schedule and eating behaviors, and considers whether diurnal preference could explain the relationship, and investigates diurnal 24-h rhythm in heart rate variability (HRV) and dietary behavior among rotating shift workers, while taking into account the sleep-wake cycle and physical activity. As a result, rotating shift work is associated with a more unbalanced diet and abnormal temporal eating patterns and that the associations may be mediated and/or modulated partly by diurnal preference. In addition, the phase angle between circadian variation in cardiac autonomic nervous system activity and the sleep-wake cycle may be associated with dietary behavior (e.g. the timing of breakfast, the ratio of energy intake at dinner to total energy intake, and total energy intake) in shift workers.
