The present study aims to investigate the relationship between effort-reward imbalance and hair cortisol concentration among teachers to examine whether hair cortisol can be a biomarker of chronic work stress.
Hair samples were collected from 39 female teachers from three kindergartens. Cortisol was extracted from the hair samples with methanol, and cortisol concentrations were measured with high performance liquid chromatography-tandem mass spectrometry. Work stress was measured using the effort-reward imbalance scale.
The ratio of effort to reward showed significantly positive association with hair cortisol concentration.
The cortisol concentration in the system increases with the effort-reward imbalance. Measurement of hair cortisol can become a useful biomarker of chronic work stress.
本研究旨在调查教师中付出-回报失衡与头发皮质醇浓度之间的关系，以检验头发皮质醇是否可作为慢性工作压力的生物标志物。
从三所幼儿园的39名女教师中采集头发样本。用甲醇从头发样本中提取皮质醇，并用高效液相色谱-串联质谱法测量皮质醇浓度。使用付出-回报失衡量表测量工作压力。
付出与回报的比率与头发皮质醇浓度呈显著正相关。
随着付出-回报失衡，体内皮质醇浓度会升高。测量头发皮质醇可成为慢性工作压力的有用生物标志物。
