Heart rate variability (HRV) captures the change in timing of consecutive heart beats and is reduced in individuals with depression and anxiety. The present study investigated whether typically-developing children without clinically recognized signs of depression or anxiety showed a relationship between HRV and depressive or anxiety symptoms. Children aged 9–14 years (N = 104) provided three minutes of cardiac signal during eyes closed rest and eyes open rest. The association between high frequency HRV, low frequency HRV, root mean square of the successive differences (RMSSD), and pNN20 versus depressive symptoms (NIH Toolbox and Child Behavior Checklist) was investigated. Results partially confirm our hypothesis, with pNN20 positively correlated with the self-reported depression measure of loneliness while controlling for age, sex, social status, and physical activity. The association was stronger in male participants. However, there is no consensus in the literature about which HRV measures are associated with depressive symptoms in healthy children. Additional studies are needed which reliably account for variables that influence HRV to establish whether certain HRV measures can be used as an early marker for depression risk in children.

心烦意乱:健康儿童心率变异性与抑郁症状之间的关联

心率变异性 (HRV) 捕捉连续心跳时间的变化,并在患有抑郁和焦虑的个体中降低。本研究调查了没有临床公认的抑郁或焦虑迹象的正常发育儿童是否显示 HRV 与抑郁或焦虑症状之间的关系。9-14 岁的儿童 (N = 104) 在闭眼休息和睁眼休息期间提供了三分钟的心脏信号。研究了高频 HRV、低频 HRV、连续差异的均方根 (RMSSD) 和 pNN20 与抑郁症状(NIH 工具箱和儿童行为检查表)之间的关联。结果部分证实了我们的假设,在控制年龄、性别、社会地位、和身体活动。这种关联在男性参与者中更强。然而,关于哪些 HRV 测量与健康儿童的抑郁症状相关,文献中没有达成共识。需要额外的研究来可靠地解释影响 HRV 的变量,以确定某些 HRV 测量值是否可以用作儿童抑郁症风险的早期标志物。
