目前还没有明确的饮食行为和昼夜变化的自主神经系统活动之间是否有关联的轮班工人。本研究探讨昼夜24小时节律的心率变异性（HRV）和饮食行为之间的轮班工人，同时考虑到睡眠-觉醒周期和体力活动。受试者为11名女性和2名男性护士或护理人员，他们在一家医疗保健机构的轮班制工作。所有受试者均被要求进行24小时心电图和步数记录，并记录每餐的时间和每种食物和饮料的消耗量。粗粒化频谱分析用于HRV的大约10分钟段，以导出周期性分量的总功率（TOT：>0.04 Hz）以及低频（LF：0.04-0.15 Hz）和高频（HF：>0.15 Hz）范围内的周期性分量的积分功率。然后计算HF功率与TOT的比值（HF nu）和LF功率与HF功率的比值（LF/HF），分别评估心脏迷走神经张力和心脏交感迷走神经平衡。单余弦分析，以获得24小时周期的变化，在这两个变量的心率变异性。在觉醒后较晚时间吃早餐的受试者，自觉醒以来表达的HF nu和LF/HF的顶相显著延迟（p<0.05）。多因素回归分析显示，早餐时间、晚餐能量摄入占总能量摄入的比例、总能量摄入与HF nu和/或LF/HF峰值相相关。这些结果表明，心脏自主神经系统活动的昼夜变化和睡眠-觉醒周期之间的相位角可能与轮班工人的饮食行为。
It has not hitherto been clarified whether there is an association between dietary behavior and circadian variation in autonomic nervous system activity among shift workers. This study examines 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. The subjects were 11 female and 2 male nurses or caregivers working in a rotating 2-shift system at a health care facility. All the subjects were asked to undergo 24-h electrocardiograph and step count recordings, and to record the time of each meal and the amounts of each food and beverage consumed. Coarse graining spectral analysis was used for approximately 10-min segments of HRV to derive the total power (TOT: >0.04 Hz) of the periodic components and the integrated power of periodic components in the low-frequency (LF: 0.04–0.15 Hz) and high-frequency (HF: >0.15 Hz) ranges. Then the ratio of HF power to TOT (HF nu) and the ratio of LF power to HF power (LF/HF) were calculated to assess cardiac vagal tone and cardiac sympathovagal balance, respectively. Single cosinor analysis was used to obtain 24-h period variations in both variables of HRV. Acrophases of HF nu and LF/HF expressed in time since awakening were significantly (p<0.05) delayed for subjects having breakfast at a later time after awakening. Multivariable regression analysis indicated that the timing of breakfast, the ratio of energy intake at dinner to total energy intake, and total energy intake were correlated to the acrophases of HF nu and/or LF/HF. These results suggest that the phase angle between circadian variation in cardiac autonomic nervous system activity and the sleep-wake cycle may be associated with dietary behavior in shift workers.
