Human biology follows recurring daily rhythms that are governed by circadian cues in the
environment. Here we show that human milk is a powerful form of “chrononutrition,” …

The daily rhythm of the hypothalamo-pituitary-adrenal (HPA) axis is regulated by the central
clock in the suprachiasmatic nucleus. Cortisol, a glucocorticoid, acts as a secondary …

Aim To evaluate the effects of almost continuous skin-to-skin contact (SSC) on salivary
cortisol, parental stress, parental depression, and breastfeeding. Study design This is a …

Importance Although infancy is the most rapid period of postnatal growth and development,
factors associated with variation in infant traits are not well understood. Objective To …

Background Cortisol concentrations in plasma display a circadian rhythm in adults and
children older than one year. Earlier studies report divergent results regarding when cortisol …

A growing body of research is demonstrating concordance between mother and child
diurnal cortisol production. In the context of maternal history of depression, intergenerational …

Background Exposure to maternal stress in utero negatively impacts cognitive and
behavioral outcomes of children born at term. The neonatal intensive care unit (NICU) can …

Introduction Separation after preterm birth is a major stressor for infants and parents. Skin-to-
skin contact (SSC) is a method of care suitable to use in the neonatal intensive care unit …

The secretion of the stress hormone cortisol follows a diurnal circadian rhythm. There are
indications that this rhythm is affected by stress early in life. This paper addresses the …

Objectives To investigate at what age preterm infants develop a salivary cortisol circadian
rhythm and identify whether it is dependent on gestational age and/or postnatal age. To …
