Heritability of daytime cortisol levels and cortisol reactivity in children
Individuals differ widely in cortisol output over the day and cortisol reactivity to challenge, both of which are relevant to disease risk. There is limited evidence concerning the heritability of these differences, so we evaluated the heritability of cortisol levels in the afternoon and cortisol reactivity using a twin design. The study involved 80 monozygotic (MZ) and 70 dizygotic (DZ) same-s...
متن کاملHeritability of daytime cortisol levels in children.
Individual differences in the level of the stress hormone cortisol play a prominent role as an explanatory variable in studies on psychopathology. Relatively few studies have paid attention to individual differences in cortisol levels and the etiology of these differences, in particular their possible genetic basis. All these studies have been in adults. The aim of this study was to estimate ge...
متن کاملHeritability of cortisol regulation in children.
BACKGROUND The normal development of cortisol regulation during childhood is thought to be influenced by a complex interplay between environmental and genetic factors. METHOD The aim of this study was to estimate genetic and environmental influences on basal cortisol levels in a sample of 151 twin pairs aged 9-16 years. Salivary cortisol was collected on two consecutive days when the children...
متن کاملEffects on cortisol reactivity
OBJECTIVES: Subordinate status and submissiveness are stressful and are often associated with ill-health. However, when there is a physical or social threat posed by more powerful others, showing submissiveness may be a good strategy to avoid or terminate conflict. One way to show submissiveness is to assume a subordinate body posture, which may also help regulate one’s own stress responses by ...
متن کاملHealth anxiety moderates the daytime cortisol slope.
OBJECTIVES Edwards et al. argue that a steeper daytime cortisol slope indicates increased symptom awareness [Edwards S, Hucklebridge F, Clow A, Evans P. Components of the diurnal cortisol cycle in relation to upper respiratory symptoms and perceived stress. Psychosom Med, 2003;65:320-7]. Theory suggests that health anxiety (HA) is associated with increased symptom awareness. Therefore, this stu...
