关于工作压力与皮质醇水平之间关系的证据并不一致，而且主要来自西方国家，对世界其他地区的推广作用有限。这些不一致可能部分是由于与唾液、血清或尿液中皮质醇分泌测量相关的方法限制。本研究旨在探讨工作压力与头发中长期综合皮质醇水平的关系，研究对象为孟加拉国达卡一家出口型成衣工厂的175名工人。工作需求（WD）、人际资源（IR）和工作价值（WV）采用心理测量学评估访谈法进行评估。WD包括四个项目，分别是体力要求、时间压力、对犯错的担忧和接触辱骂性语言。IR包括五个项目，分别是支持、认可、适当的报酬、工人对管理层的信任以及工人所感知的管理层对工人的信任。WV通过三项指标衡量了工作保障、晋升前景和工作自由度。采用液相色谱-质谱法分析毛发皮质醇浓度（HCC）。使用逐步多变量线性回归模型（反向消除预测因子）来估计HCC与三种工作压力成分的关联。对于显著的工作压力成分，进一步进行多变量线性回归分析，以探讨是否，如果是，哪个单独的项目(s)贡献最大。HCC平均为3.27 pg/mg （SD 2.58）。HCC与WV显著相关（β = 0.209, p = 0.021）。对三个WV项目的进一步分析显示，这种关联在很大程度上是由“晋升前景”项目驱动的（beta = 0.230, p = 0.007），这意味着良好晋升前景的感知与较高的HCC相关。HCC升高与良好晋升前景的发现最初似乎是违反直觉的，但有研究证明，工作晋升可能导致心理健康状况恶化。此外，在孟加拉国的RMG行业中晋升可能是一种紧张的经历：在这种情况下，工作晋升很少，而且需要满足与工作有关的特殊要求。需要从种族和文化多样化的职业环境中进行进一步的研究来验证这一假设，以阐明我们研究结果的可重复性，并提高我们对跨文化和背景的社会心理工作条件的心理生物学含义的理解。(C) 2014年作者。Elsevier Ltd.出版。
Evidence on the association of work stress with cortisol levels is inconsistent and mostly stems from Western countries, with limited generalizability to other regions of the world. These inconsistencies may partly be due to methodological limitations associated with the measurement of cortisol secretion in saliva, serum or urine. The present study set out to explore associations of work stress with long-term integrated cortisol levels in hair among 175 workers of an export oriented ready-made garment (RMG) factory in Dhaka, Bangladesh.Work-related demands (WD), interpersonal resources (IR) and work-related values (WV) were assessed using a psychometrically evaluated interview. WD consisted of four items on physical demands, time pressure, worries about mistakes and exposure to abusive language. IR comprised five items addressing support, recognition, adequate payment, workers' trust in the management, and the management's trust in workers, as perceived by the workers. WV captured job security, promotion prospects and job latitude by three items. Hair cortisol concentrations (HCC) were analyzed by liquid chromatography-mass spectrometry. Stepwise multivariable linear regression models (backward elimination of predictors) were used to estimate associations of HCC with the three work stress components. For significant work stress component(s), further multivariable linear regression analyses were conducted to explore whether, and if so, which individual item (s) contributed most.The mean HCC equaled 3.27 (SD 2.58) pg/mg. HCC were found to be significantly associated with WV (beta = 0.209, p = 0.021). Additional analyses of the three WV items revealed that this association was largely driven the item on "promotion prospects" (beta = 0.230, p = 0.007) implying that the perception of good promotion prospects was associated with higher HCC.The finding of elevated HCC with good promotion prospects may initially seem counter-intuitive, but is supported by research documenting that job promotion may result in poorer mental wellbeing. Moreover, being promoted in the Bangladeshi RMG industry may represent a stressful experience: job promotions are rare in this setting and are associated with the need to meet exceptional job-related demands. Further research from ethnic and culturally diverse occupational settings is needed to test this hypothesis, to shed light on the reproducibility of our findings and to improve our understanding of the psychobiological implications of psychosocial working conditions across cultures and contexts.
