To investigate the association between work stress measures and salivary cortisol excretion in working and weekend days.
In a sample of 68 healthy young call-centre operators dimensions of job stress from the demand-control model were related to repeated measures of salivary cortisol on seven samples (at awakening, +30 min, +60 min, + 3 h, +6 h, +9 h, and +12 h after awakening) at two working days and a weekend day.
The cortisol excretion on work days was higher than during weekend day with gender-specific differences as women only showed higher significant values for area under the curve (AUC(G)) and Diurnal cycle (chi(2) (2) = 8.10, P < 0.05; chi(2) (2) = 15.75, P < 0.05, respectively). There were no associations between job demand, job control and cortisol excretion, while the sociodemographic characteristics of the call-centre operators showed linear relation with the diurnal pattern of cortisol secretory activity.
The hypothalamic-pituitary adrenocortical axis activation was higher in working day than in weekend day. This activation measured by salivary cortisol was not related to self-reported mental stressors assessed with job strain model. The availability of more specific psychometric scales would be useful to explore the relationship between salivary cortisol levels and measures of mental stress at workplace.
研究工作日和周末工作压力指标与唾液皮质醇排泄之间的关联。
对68名健康的年轻呼叫中心操作员样本，采用需求 - 控制模型中的工作压力维度，与在两个工作日和一个周末日采集的七个样本（觉醒时、觉醒后30分钟、60分钟、3小时、6小时、9小时和12小时）的唾液皮质醇重复测量值相关联。
工作日的皮质醇排泄高于周末，存在性别差异，因为仅女性的曲线下面积（AUC(G)）和昼夜周期显示出更高的显著值（分别为χ(2)(2)=8.10，P<0.05；χ(2)(2)=15.75，P<0.05）。工作需求、工作控制与皮质醇排泄之间无关联，而呼叫中心操作员的社会人口统计学特征与皮质醇分泌活动的昼夜模式呈线性关系。
下丘脑 - 垂体 - 肾上腺皮质轴的激活在工作日高于周末。通过唾液皮质醇测量的这种激活与用工作压力模型评估的自我报告的精神压力源无关。更具体的心理测量量表将有助于探索唾液皮质醇水平与工作场所精神压力指标之间的关系。
