OBJECTIVES
This report investigates whether there is any association between sense of coherence (SOC), as a coping measure in confronting stressful conditions, and heart rate variability (HRV), as a measure of the cardiac autonomic nervous system during the daily life pattern.
METHODS
Sixteen healthy university students (14 males and 2 females) filled in the validated Japanese version of the SOC-13 questionnaire before being informed about the study protocol. For each participant, we calculated 5-minute HRV indices using logarithmically transformed data on frequency domains for HRV derived by 24-hour Holter monitoring. Frequency domains for HRV recordings were investigated for the 24-hour time periods.
RESULTS
The correlation coefficient between the SOC scores and the high frequency power of HRV (0.15-0.40) was positively significant during the resting sitting position (r≥0.60, P<0.05). After grouping SOC scores by the median, the high frequency domain of HRV was higher in high SOC subjects for most of the 24-hour time period.
CONCLUSION
A higher SOC could modulate the parasympathetic tone of cardiac autonomic activity, especially during the resting sitting position.
目的
本报告旨在探讨应对压力情境的应对措施——心理一致感（SOC）与日常生活模式中心率变异性（HRV）——心脏自主神经系统的测量指标之间是否存在关联。
方法
16 名健康的大学生（14 名男性和 2 名女性）在了解研究方案之前填写了经过验证的 SOC-13 问卷的日文版。对于每个参与者，我们使用 24 小时动态心电图监测得出的 HRV 频域的对数转换数据计算了 5 分钟的 HRV 指数。对 HRV 记录的频域进行了 24 小时时间周期的研究。
结果
在休息坐姿时，SOC 评分与 HRV 的高频功率（0.15-0.40）之间的相关系数呈正显著（r≥0.60，P<0.05）。按中位数分组 SOC 评分后，在大多数 24 小时时间周期内，SOC 较高的受试者 HRV 的高频域较高。
结论
较高的 SOC 可能会调节心脏自主活动的副交感神经张力，尤其是在休息坐姿时。
