本研究旨在探讨职业状况和工作压力因素对日本工人心血管应激反应的影响。在2001年至2009年在日本大阪进行的这项基线评估中，我们调查了928名健康的日本员工(330名男性，598名女性)，他们来自两种职业状态：经理/专业人员和普通工人。使用简单的工作压力问卷来评估工作压力水平。测量安静时和两次应激任务时的收缩压和舒张压(SBP、DBP)、心率、心率变异性(高频、低频、LF/HF)和外周血流量。应激反应的变化被计算为在任务和休息期间测量的变量之间的差值。男性在定量工作负荷与舒张压、心率和低频/高频之间、身体需求与血压(SBP、DBP)之间以及恶劣的身体环境与高频之间显示出负相关关系。男性在质的工作负荷与心率、身体需求与外周血流量之间也有正相关关系(均P<0.05)。女性定性工作负荷与SBP呈负相关，与外周血流量呈正相关，而恶劣的物理环境与SBP呈正相关(均P<0.05)。当按职业地位分层时，在男性经理/专业人员和女性普通工人中，观察到工作压力和压力反应性变化之间的显著关联(p<0.05)。工作压力水平与男性和女性心血管应激反应的变化有关。职业状况可能会改变这些联系。工作压力源与男性和女性压力反应性的变化有关。男性经理/专业人员中与压力反应相关的工作压力源。女性普通工人的工作压力源与应激反应有关。应考虑职业地位和性别差异。
This study aimed to investigate the effects of occupational status and job stress factors on cardiovascular stress reactivity in Japanese workers. In this baseline assessment between 2001 and 2009 in Osaka, Japan, we examined 928 healthy Japanese employees (330 men, 598 women) from two occupational statuses: managers/professionals and general workers. A brief job stress questionnaire was used to evaluate job stress levels. Systolic and diastolic blood pressure (SBP, DBP), heart rate, heart rate variability (high-frequency [HF], low-frequency [LF], LF/HF], and peripheral blood flow were measured at rest and during two stressful tasks. Changes in stress reactivity were calculated as the difference between the measured variables during the tasks and the rest period. Men showed inverse associations between quantitative job overload and DBP, heart rate, and LF/HF, between physical demands and blood pressure (SBP, DBP), and between a poor physical environment and HF. Men also had positive associations between qualitative job overload and heart rate, and between physical demands and peripheral blood flow (all p < 0.05). Women showed inverse associations between qualitative job overload and SBP, and showed positive associations between qualitative job overload and peripheral blood flow, and between a poor physical environment and SBP (all p < 0.05). When stratified by occupational status, significant associations between job stress and changes in stress reactivity were observed in male managers/professionals and female general workers (p < 0.05). Job stress levels are associated with changes in cardiovascular stress reactivity in men and women. Occupational status may modify these associations. Job stressors are associated with changes in stress reactivity in men and women. Job stressors associated with stress reactivity in male managers/professionals. Job stressors associated with stress reactivity in female general workers. Occupational status and gender differences should be considered.
