应激是一个复杂的现象，由两个主要的神经系统协调：下丘脑-垂体-肾上腺系统与皮质醇作为经典的应激生物标志物和自主神经系统与心率变异性（HRV）作为最近提出的应激标志物。为了测试低HRV（5分钟测量）作为幼儿（5- 10岁）的压力指标，进行了与自我报告的慢性压力方面（事件，情绪和问题）（N=334）和唾液皮质醇（N=293）的关联。同伴问题、愤怒、焦虑和悲伤与较低的连续差异均方根（RMSSD）和高频功率（即较低的副交感神经活动）相关。焦虑和愤怒也与较高的低频与高频比率有关。使用多层次模型，较高的皮质醇水平，更大的皮质醇觉醒反应和陡峭的昼夜下降也与这些HRV模式较低的副交感神经活动。结论：低副交感神经活性（HRV）可作为儿童应激指标。(C)2013 Elsevier B.

Stress is a complex phenomenon coordinated by two main neural systems: the hypothalamic-pituitary-adrenal system with cortisol as classical stress biomarker and the autonomic nervous system with heart rate variability (HRV) as recently suggested stress marker. To test low HRV (5 minute measurements) as stress indicator in young children (5-10y), associations with self-reported chronic stress aspects (events, emotions and problems) (N=334) and salivary cortisol (N=293) were performed. Peer problems, anger, anxiety and sadness were associated with lower root mean square of successive differences (RMSSD) and high frequency power (i.e. lower parasympathetic activity). Anxiety and anger were also related to a higher low frequency to high frequency ratio. Using multilevel modelling, higher cortisol levels, a larger cortisol awakening response and steeper diurnal decline were also associated with these HRV patterns of lower parasympathetic activity. Conclusion: Low HRV (lower parasympathetic activity) might serve as stress indicator in children. (C) 2013 Elsevier B.V. All rights reserved.
