In children, objective data carried out from sleep EEG monitoring are scarce. Furthermore, results associating the hypothalamic–pituitary–adrenocortical (HPA)-activity with sleep EEG measurements in children are missing. Therefore, our study aimed to investigate in preschool-children the association between sleep patterns and endocrine activity. Furthermore, children’s behavioral/emotional difficulties and competences were assessed in order to correlate psychological strain with sleep measures.
