Associations between perceived stress and cortisol biomarkers in predominantly Latino adolescents.

ABSTRACT: The relationship between cortisol and perceived stress is poorly understood. We sought to determine whether perceived stress is associated with cortisol biomarkers in adolescents. In a sample of 229 adolescents (mean age = 15.8 years) we measured perceived stress with the 14-item Perceived Stress Scale (PSS) questionnaire, serum cortisol (sCOR), salivary Cortisol Awakening Response (CAR: 30-minute post-awakening - awakening), salivary Diurnal Cortisol Slope (DCS: evening-awakening), and total daily salivary cortisol (TDC). Multivariable linear regression was used to estimate baseline associations between PSS, TDC, and sCOR Mixed effects linear regression was used to estimate baseline associations between PSS and CAR and DCS. A twelve-week longitudinal association between PSS and cortisol b
