The purpose of this study was to explore whether work strain (i.e., job demands and job control) and subjective need for recovery (NFR) after work are related to measured concentration of cumulative cortisol.
Participants were 43 teachers recruited from kindergarten. They self-reported their NFR, job demands and job control over the last month. NFR was measured with the NFR scale. Job demands and control were assessed with the Chinese version of the Job Content Questionnaire. Hair cortisol was used to represent cumulative cortisol excretion. Hair cortisol concentration (HCC) was measured with high-performance liquid chromatography-tandem mass spectrometry.
No significant correlations were found between job demands or job control and HCC. NFR was significantly and inversely correlated with HCC (r = -0.41, p = 0.006). The inverse association between NFR and HCC remained significant when age and job demands and job control were controlled for (p = 0.02).
The activity of the hypothalamic-pituitary-adrenal axis declines with the accumulation of NFR after working time.
本研究旨在探讨工作压力（即工作要求和工作控制）以及下班后的主观恢复需求（NFR）是否与测量的累积皮质醇浓度相关。
研究对象为从幼儿园招募的43名教师。他们自我报告了过去一个月的NFR、工作要求和工作控制情况。NFR采用NFR量表进行测量。工作要求和控制情况通过中文版工作内容问卷进行评估。头发皮质醇用于代表累积皮质醇排泄。头发皮质醇浓度（HCC）采用高效液相色谱-串联质谱法进行测量。
未发现工作要求或工作控制与HCC之间存在显著相关性。NFR与HCC呈显著负相关（r = -0.41，p = 0.006）。在控制年龄、工作要求和工作控制后，NFR与HCC之间的负相关仍然显著（p = 0.02）。
工作后随着NFR的积累，下丘脑-垂体-肾上腺轴的活动会下降。
