Stress. 2021 Nov;24(6):763-771. doi: 10.1080/10253890.2021.1919615. Epub 2021 Apr 30.
This study aimed to investigate the association of perceived stress and salivary cortisol levels with the snack and fast-food dietary pattern in a sample of women shift workers. We conducted a cross-sectional study of 539 women aged 18-53 years working in the production line of a poultry processing plant. Stress was assessed with the 10-item Perceived Stress Scale (PSS-10) and by salivary cortisol levels (immediately after waking and upon returning home from work). Dietary patterns were identified by principal component analysis. We used linear and Poisson regression models to assess multivariable-adjusted associations of perceived stress and salivary cortisol levels with the snack and fast-food dietary pattern. After adjustments, women with higher PSS-10 scores had a 28% higher probability (95% confidence interval, 1.04-1.56) of consuming snacks/fast food. Mean (SD) waking cortisol levels were inversely associated with quartiles of the dietary pattern: Q1, 6.63 (0.43) nmol/L; Q2, 6.00 (0.38) nmol/L; Q3, 5.62 (0.40) nmol/L; and Q4, 5.29 (0.35) nmol/L ( = 0.019). Perceived stress was not associated with salivary cortisol levels. The work shift was not associated with perceived stress or cortisol levels. This study demonstrated an association of psychological and physiological measures of stress with a dietary pattern characterized by high intakes of hyper-palatable, energy-dense, ready-to-eat foods among women shift workers.
本研究旨在调查女性轮班工人样本中感知压力和唾液皮质醇水平与零食及快餐饮食模式之间的关联。我们对一家家禽加工厂生产线的539名年龄在18 - 53岁的女性进行了横断面研究。通过10项感知压力量表（PSS - 10）和唾液皮质醇水平（醒来后及下班回家时）评估压力。通过主成分分析确定饮食模式。我们使用线性和泊松回归模型评估感知压力和唾液皮质醇水平与零食及快餐饮食模式的多变量调整关联。调整后，PSS - 10得分较高的女性食用零食/快餐的概率高28%（95%置信区间，1.04 - 1.56）。醒来时皮质醇水平的均值（标准差）与饮食模式四分位数呈负相关：第一四分位数，6.63（0.43）nmol/L；第二四分位数，6.00（0.38）nmol/L；第三四分位数，5.62（0.40）nmol/L；第四四分位数，5.29（0.35）nmol/L（ = 0.019）。感知压力与唾液皮质醇水平无关。轮班工作与感知压力或皮质醇水平无关。本研究表明，在女性轮班工人中，压力的心理和生理指标与以高摄入量的美味、高能量、即食食品为特征的饮食模式之间存在关联。
