We explored the association between subjective snoring frequency and heart rate variability (HRV) in a healthy adolescent population.
A total of 102 healthy adolescents were recruited from high schools in South Korea, and reported their sleep habits and snoring frequency. HRV was assessed to indirectly measure autonomic function. We assessed correlations between snoring frequency and HRV indices. We also investigated the effects of sex and behaviorally induced insufficient sleep syndrome (BISS) on the associations between HRV parameters and snoring frequency.
Overall, significant correlations were apparent between snoring frequency and HRV indices including the standard deviation of the normal-to-normal intervals (SDNN) and the low-frequency/high-frequency (LF/HF) ratio. Associations were more evident in males and those with BISS compared to females and those without BISS.
Our findings suggest that snoring changes autonomic nervous system (ANS) activity in adolescents; the changes are more dramatic in males and those with insufficient sleep.
我们探究了健康青少年人群中主观打鼾频率与心率变异性（HRV）之间的关系。
我们从韩国的高中招募了 102 名健康青少年，让他们报告自己的睡眠习惯和打鼾频率。我们评估了 HRV，以间接衡量自主神经功能。我们评估了打鼾频率与 HRV 指标之间的相关性。我们还调查了性别和行为性睡眠不足综合征（BISS）对 HRV 参数与打鼾频率之间关联的影响。
总体而言，打鼾频率与 HRV 指标（包括正常-正常间隔标准差（SDNN）和低频/高频（LF/HF）比值）之间存在显著相关性。与女性和无 BISS 者相比，男性和 BISS 者的相关性更为明显。
我们的研究结果表明，打鼾会改变青少年的自主神经系统（ANS）活动；在男性和睡眠不足者中，这种变化更为明显。
