背景：近年来，互联网在世界范围内越来越受欢迎，但失去对互联网使用的控制可能会对我们的日常生活产生负面影响。目的：通过心率变异性分析，探讨网络成瘾对自主神经系统功能的影响。方法：采用横断面设计。数据来自240名学龄儿童，他们完成了中国网络成瘾量表和匹兹堡睡眠质量指数问卷。采用光谱分析法测定HRV。采用独立t检验比较两组间特征及HRV的差异。采用双向方差分析来检验各组HRV的差异。结果：网络成瘾者高频率、对数变换高频率、对数变换总功率显著低于非网络成瘾者，低频率显著高于非网络成瘾者。与不失眠的网络成瘾者相比，有失眠的网络成瘾者有更高的低频百分比和更低的高频百分比、对数变换的高频百分比和对数变换的总功率。结论：网络成瘾与高交感神经活动和低副交感神经活动有关。与网络成瘾相关的自主神经失调可能部分是由失眠引起的，但其机制仍需进一步研究。
Background: The Internet has been gaining worldwide popularity in recent years, but a loss of control over Internet use might lead to negative impacts on our daily lives. Objectives: This study explored the effects of Internet addiction on autonomic nervous system function through heart rate variability (HRV) analysis. Methods: This was a cross-sectional design. Data were collected from 240 school-aged children who completed the Chinese Internet Addiction Scale and Pittsburgh Sleep Quality Index questionnaires. Spectral analysis was used to measure HRV. Independent t test was used to compare differences in characteristics and HRV between groups. A 2-way analysis of variance was used to examine group differences in HRV. Results: Internet addicts had significantly lower high frequency (HF) percentage, logarithmically transformed HF, and logarithmically transformed total power and significantly higher low frequency percentage than did nonaddicts. Internet addicts who had insomnia had higher low frequency percentage and lower HF percentage, logarithmically transformed HF, and logarithmically transformed total power compared with nonaddicts who did not have insomnia. Conclusions: Internet addiction is associated with higher sympathetic activity and lower parasympathetic activity. The autonomic dysregulation associated with Internet addiction might partly result from insomnia, but the mechanism still needs to be further studied.
