Night-shift workers may develop poor cardiovascular health. Studies about heart rate variability (HRV) metrics could identify risk factors in this population and be used to examine the effectiveness of interventions for optimizing the health of night-shift workers. The purpose of this review was to examine the use of HRV methodologies in studies about night-shift work. Overall, 34 articles met the selection criteria and underwent a methodological critique. The main conclusion across these studies was that night-shift work could increase the sympathetic influences on the variability between heartbeats. In many cases, however, important methodological details were omitted (e.g., the number and duration of electrocardiogram recordings, sampling rates, R-R segment duration, wavelet transform methods). Recommendations include adding measures of disease outcomes, using ≥250 Hz sampling rates and 600-s R-R segments, and measuring sleep and circadian rhythms. With these approaches, researchers can design investigations that identify therapeutic targets for improving the health of night-shift workers. Int J Occup Med Environ Health. 2020;33(4):409-25.
夜班工人可能会出现心血管健康状况不佳的情况。有关心率变异性 (HRV) 指标的研究可以确定该人群的风险因素，并用于检查优化夜班工人健康的干预措施的效果。本综述的目的是检查 HRV 方法在夜班工作研究中的应用。总体而言，有 34 篇文章符合选择标准并经过了方法学评估。这些研究的主要结论是，夜班工作会增加心跳之间变异性的交感神经影响。然而，在许多情况下，重要的方法学细节被省略了（例如，心电图记录的数量和持续时间、采样率、R-R 段持续时间、小波变换方法）。建议包括添加疾病结果的测量、使用≥250 Hz 的采样率和 600 秒的 R-R 段，并测量睡眠和昼夜节律。通过这些方法，研究人员可以设计出确定治疗目标的研究，以改善夜班工人的健康状况。国际职业医学与环境卫生杂志。2020;33(4):409-25.
