目的是研究工作压力源的感知与动态测量心率变异性（HRV）的关系。结果是根据1976-1978年进行的比利时身体健康研究中653名40-55岁健康男性工人的样本得出的。资料收集采用自填问卷和生物临床检查。在工作压力问卷的基础上，构建了包含5个项目的生理和心理工作压力源指数。通过工作日24小时动态心电图记录收集HRV数据。计算了HRV的时域和频域测度。通过相关分析、多元线性回归分析和（co）方差分析评估工作压力源与HRV测量的相关性。工作压力源指数与较低的pNN50（相邻正常RR间隔之间的差异百分比> 50 ms）、较低的高频功率和较高的低频与高频功率之比显著相关。在调整了年龄、语言、职业、吸烟、体重指数、总胆固醇、收缩压和闲暇时间体育活动等因素后，得到了非常相似的结果。与SDNN（所有正常RR区间的标准差）和低频功率无显著关联。在653名健康男性工人的样本中，工作压力源的感知与副交感神经活动的减少有关。这些发现支持了一种观点，即自主神经系统的副交感神经成分与工作压力有关。
The aim was to examine the perception of work stressors in relation to ambulatory measures of heart rate variability (HRV).Results are based on a sample of 653 healthy male workers aged 40-55 from the Belgian Physical Fitness Study conducted in 1976-1978. Data were collected by means of self-administered questionnaires and bio-clinical examinations. An index of physical and psychosocial work stressors containing five items was constructed based on the job stress questionnaire. Data on HRV were collected by means of 24-h ambulatory ECG recordings on a working day. Both time and frequency domain measures of HRV were calculated. Associations between work stressors and HRV measures were assessed by means of correlations, multiple linear regression analysis and analysis of (co)variance.The work stressor index was significantly associated with lower pNN50 (the percentage of differences between adjacent normal RR intervals > 50 ms), lower high frequency power and a higher ratio of low frequency over high frequency power. Very similar results were obtained after adjusting for age, language, occupation, smoking, body mass index, total cholesterol, systolic blood pressure and leisure time physical activity. No significant associations were found with SDNN (the standard deviation of all normal RR intervals) and low frequency power.The perception of work stressors was related to reduced parasympathetic activity in a sample of 653 healthy male workers. These findings support the idea that particularly the parasympathetic component of the autonomic nervous system is related to work stress.
