Background: Obesity has been associated with perturbations of the hypothalamic┬ľpituitary┬ľadrenal (HPA) axis and the sympathetic nervous system (SNS). Scalp hair cortisol has been recognized as a reliable index of long-term cortisol concentrations.Objective and hypotheses: Aim of this study was to compare indices of HPA axis and SNS activities, such as, respectively, the salivary cortisol and alpha-amylase diurnal patterns, and their relations i...

Background: Chronic stress and increased adiposity have been associated with each other in children. Further studies are needed, however, to evaluate both the directionality of this association and the mediating metabolic mechanisms.Objective and hypotheses: This study investigates the interrelations between BMI, body composition parameters, indices of the stress response, such as hair and salivary cortisol levels, and, metabolic mediators, such as insul...
