Obesity is a risk factor of cardiovascular disease-related mortality and may be associated with changes in the autonomic nerve activity. Nurses working shifts and caring for patients are under great mental and physical pressure, and research has proven that these can negatively affect the body. The objective of this study was to examine the influence of obesity in nurses on their heart rate variability (HRV) and determine whether age or shift type moderates this influence. A questionnaire survey and HRV measurements were conducted on nurses at a hospital in Taiwan during a routine employee health checkup. HRV analysis was conducted using a noninvasive HRV monitor for five minutes. A total of 242 nurses with a mean age of 28.98 ± 6.56 years were enrolled in this study. An overly large waist circumference (WC) had a negative impact on high frequency (HF), low frequency (LF), and standard deviation of normal-to-normal interval (SDNN), while an overly high body mass index (BMI) had a negative impact on very low frequency (VLF) and SDNN. The interaction term "overly large WC × age" had a negative impact on HF ( = -0.21, = 0.010) and LF ( = -0.18, = 0.030), whereas the interaction term "overly high BMI×age" had a negative impact on HF ( = -0.27, = 0.001), LF ( = -0.19, = 0.023), and VLF ( = -0.17, = 0.045). The interaction terms "overly large WC × shift type" and "overly high BMI × shift type" did not influence any HRV parameters. As age increased, so did the degree to which the HF and LF of nurses with an overly large WC were lower than normal, and so did the degree to which the HF, LF, and VLF of nurses with an overly high BMI were lower than normal.
肥胖是心血管疾病相关死亡率的一个风险因素，可能与自主神经活动的变化有关。轮班工作并照顾病人的护士承受着巨大的身心压力，研究已经证明这些压力会对身体产生负面影响。本研究的目的是检查肥胖对护士心率变异性（HRV）的影响，并确定年龄或轮班类型是否会调节这种影响。在台湾一家医院的常规员工体检期间，对护士进行了问卷调查和 HRV 测量。使用非侵入性 HRV 监测器对护士进行了五分钟的 HRV 分析。共有 242 名平均年龄为 28.98 ± 6.56 岁的护士参加了这项研究。过大的腰围（WC）对高频（HF）、低频（LF）和正常到正常间隔标准差（SDNN）有负面影响，而过高的体重指数（BMI）对极低频（VLF）和 SDNN 有负面影响。“过大 WC×年龄”的交互项对 HF（= -0.21，= 0.010）和 LF（= -0.18，= 0.030）有负面影响，而“过高 BMI×年龄”的交互项对 HF（= -0.27，= 0.001）、LF（= -0.19，= 0.023）和 VLF（= -0.17，= 0.045）有负面影响。“过大 WC×轮班类型”和“过高 BMI×轮班类型”的交互项对任何 HRV 参数都没有影响。随着年龄的增长，过大 WC 护士的 HF 和 LF 比正常水平越低，而过高 BMI 护士的 HF、LF 和 VLF 比正常水平越低。
