Effort reward imbalance (ERI) is suggested to increase risk for stress and is hypothesized to increase cortisol levels, especially the awakening cortisol response, ACR.
In 2006 and 2008, 480 individuals collected saliva samples at awakening and 30 min post-awakening. Mixed effects models with subject as a random effect and appropriate covariates were used to evaluate associations between the Effort Reward Model, and salivary cortisol at awakening (S0), and ACR.
ERI was negatively and significantly associated with S0 for women and positively associated with ACR. S0 and ACR increased significantly from 2006 to 2008.
ERI was significantly associated with cortisol levels at awakening (inverse association) for women, and positively associated with ACR. The population experienced a significant increase in morning cortisol levels and ACR from 2006 to 2008, which may originate in a re-organization of the included work places.
努力-回报失衡（ERI）被认为会增加压力风险，并假设会增加皮质醇水平，尤其是觉醒皮质醇反应（ACR）。
在 2006 年和 2008 年，480 名个体在觉醒时和觉醒后 30 分钟收集唾液样本。采用以个体为随机效应和适当协变量的混合效应模型，评估努力-回报模型与觉醒时唾液皮质醇（S0）和 ACR 之间的关系。
ERI 与女性的 S0 呈负相关且显著相关，与 ACR 呈正相关。S0 和 ACR 从 2006 年到 2008 年显著增加。
ERI 与女性的觉醒皮质醇水平呈显著负相关（反比关系），与 ACR 呈正相关。从 2006 年到 2008 年，人群的早晨皮质醇水平和 ACR 显著增加，这可能源于所包含工作场所的重新组织。
