失眠症患者睡眠质量与心理健康状况及心率变异性的关系

Relationship between the quality of sleep and the mental health situation,the heart rate variability in patients of insomnia

目的:探讨失眠症患者睡眠质量与心理健康状况及心率变异性(HRV)的关系。方法:对165例失眠症患者进行匹兹堡睡眠质量指数问卷(PSQI)评估,并据此分为高分组85例与低分组80例;采用生理相干与自主平衡训练系统(SPCS)采集HRV,应用症状自评量表(SCL-90)评估患者心理健康状况。结果:高分组SCL-90中焦虑因子及睡眠与饮食因子得分显著高于低分组(P均<0.05);两组患者HRV中总功率(TP)、低频功率(LF)、高频功率(HF)、LF/HF比值差异有统计学意义(P均<0.05);PSQI总分与HRV中TP、LF、HF呈正相关(r=0.196,0.185,0.223;P<0.05或P<0.01),与LF/HF呈负相关(r=-0.304,P<0.01)。结论:严重失眠的患者易产生焦虑情绪;失眠严重程度与自主神经系统功能失调程度相关。

Objective： To explore the relationship between the quality of sleep and the mental health situa- tion,the heart rate variability（HRV） in patients of insomnia. Method：The insomnia state of 165 patients with insomnia were assessed by the Pittsburgh sleep quality Index（ PSQI）, and all patients were divided into high score group （85 cases） and low score group （80 cases） ,according to the total scores of PSQI. The data of HRV were collected by Self-generate Physiological Coherence System（SPCS） ,the mental health state were assessed by symp- tom checklist-90（SCL-90）. Results：The factor scores of anxiety, sleep and diet in high score group were sig- nificantly higher than those in low score group in SCL-90（ all P 〈 0.05 ）. The difference of total power （TP） ,low frequency power （LF） ,high frequency power （HF） and LF/HF in HRV between the two groups had statistical significance （all P 〈 0. 05 ）. The total scores of PSQI were positively correlated to TP, LF and HF in HRV （ r = 0. 196,0. 185,0. 223 ;P 〈0. 05 or P 〈0.01 ） ,but the total scores of PSQI were negatively correlated to LF/HF in HRV （r = -O. 304,P 〈 0. 01 ）. Conclusion： Patients with severe insomnia are more prone to anxiety, and the severity of insomnia is associated with dysfunction of autonomic nervous system. Key words： insomnia; heart rate variability; the mental health state
