Vagus nerve functioning, as indexed by high-frequency heart rate variability (HF-HRV), has been implicated in a wide range of mental and physical health conditions, including sleep complaints. This study aimed to test associations between HF-HRV measured during sleep (sleep HF-HRV) and subjective sleep complaints 4 years later.
One hundred forty-three healthy employees (91% male; MAge = 47.8 years [time 2], SD = 8.3 years) of an industrial company in Southern Germany completed the Jenkins Sleep Problems Scale, participated in a voluntary health assessment, and were given a 24-hour ambulatory heart rate recording device in 2007. Employees returned for a health assessment and completed the Jenkins Sleep Problems Scale 4 years later.
Hierarchical regression analyses showed that lower sleep HF-HRV measured in 2007 was associated with higher self-reported sleep complaints 4 years later after controlling for covariates (rab,c = -0.096, b = -0.108, 95% CI, -0.298 to 0.081, ΔR2 = 0.009, p = .050).
These data are the first to show that lower sleep HF-HRV predicted worse sleep 4 years later, highlighting the importance of vagus nerve functioning in adaptability and health.
心率高频变异性（HF-HRV）作为迷走神经功能的指标，与广泛的身心健康状况有关，包括睡眠问题。本研究旨在测试睡眠期间测量的 HF-HRV（睡眠 HF-HRV）与 4 年后主观睡眠抱怨之间的关联。
德国南部一家工业公司的 143 名健康员工（91%为男性；平均年龄=47.8 岁[时间 2]，标准差=8.3 岁）完成了詹金斯睡眠问题量表，参加了自愿健康评估，并在 2007 年接受了 24 小时动态心率记录设备。员工在 4 年后返回进行健康评估并完成詹金斯睡眠问题量表。
分层回归分析显示，2007 年测量的较低的睡眠 HF-HRV 与 4 年后自我报告的睡眠问题更高相关，在控制协变量后（rab,c=-0.096，b=-0.108，95%CI：-0.298 至 0.081，ΔR2=0.009，p=0.050）。
这些数据首次表明，较低的睡眠 HF-HRV 预测 4 年后的睡眠质量更差，突出了迷走神经功能在适应性和健康中的重要性。
