<abstract> <title>Abstract</title> <p> <italic>Context</italic>: Characterization of stress exposure requires understanding seasonal variability in stress biomarkers.</p> <p> <italic>Objective</italic>: To compare acute and chronic stress biomarkers between two seasons in a cohort of rural, Hispanic mothers.</p> <p> <italic>Methods</italic>: Stress questionnaires and cortisol measurements (hair, blood and saliva) were collected in the summer and fall.</p> <p> <italic>Results</italic>: Cortisol biomarkers were significantly different and stress questionnaires were significantly correlated between seasons.</p> <p> <italic>Discussion</italic>: The variability in cortisol and relative stability of questionnaires between seasons may indicate that cortisol responds to subtle stressors not addressed in questionnaires.</p> <p> <italic>Conclusions</italic>: There are significant differences in stress biomarkers in our cohort between seasons.</p> </abstract>
