Characterization of stress exposure requires understanding seasonal variability in stress biomarkers.
To compare acute and chronic stress biomarkers between two seasons in a cohort of rural, Hispanic mothers.
Stress questionnaires and cortisol measurements (hair, blood and saliva) were collected in the summer and fall.
Cortisol biomarkers were significantly different and stress questionnaires were significantly correlated between seasons.
The variability in cortisol and relative stability of questionnaires between seasons may indicate that cortisol responds to subtle stressors not addressed in questionnaires.
There are significant differences in stress biomarkers in our cohort between seasons.
对压力暴露的特征描述需要了解压力生物标志物的季节性变化。
比较一组农村西班牙裔母亲在两个季节中的急性和慢性压力生物标志物。
在夏季和秋季收集压力问卷以及皮质醇测量数据(头发、血液和唾液)。
皮质醇生物标志物在不同季节间存在显著差异,压力问卷在不同季节间显著相关。
皮质醇的变化以及问卷在不同季节间的相对稳定性可能表明,皮质醇对问卷中未涉及的细微压力源有反应。
我们队列中的压力生物标志物在不同季节间存在显著差异。
