Autonomic nervous system functioning, measured with heart rate variability (HRV), is associated with emotion regulation and likely contributes to binge eating. This study examined the link between HRV and binge eating severity and analyzed changes in HRV as a marker of emotion regulation in individuals with binge eating. Participants (n = 28) with obesity and loss of control eating reported overeating and loss of control episodes and completed an HRV assessment at rest and during a mental stressor. At rest, lower time-domain HRV was linked to more severe loss of control (SDNN B = -0.18, p = 0.03). Frequency-domain HRV was associated with more severe overeating (LFn B = 14.92, p = 0.03; HFn B = -14.81, p = 0.04). Frequency-domain HRV differed between resting and stressed conditions (p's < 0.001). Findings contribute to understanding emotion regulation in binge eating and guide future research and novel intervention development.
自主神经系统功能，通过心率变异性（HRV）来衡量，与情绪调节有关，可能与暴饮暴食有关。本研究探讨了 HRV 与暴饮暴食严重程度之间的联系，并分析了 HRV 作为暴饮暴食个体情绪调节的标志物的变化。参与者（n=28）肥胖且失去对进食的控制，报告了暴饮暴食和失去控制的发作，并在休息和心理压力源下完成了 HRV 评估。在休息时，较低的时域 HRV 与更严重的失去控制有关（SDNN B=-0.18，p=0.03）。频域 HRV 与更严重的暴饮暴食有关（LFn B=14.92，p=0.03；HFn B=-14.81，p=0.04）。频域 HRV 在休息和压力条件下有差异（p<0.001）。研究结果有助于理解暴饮暴食中的情绪调节，并指导未来的研究和新的干预措施的发展。
