Catecholamine and cortisol excretion patterns in three-year-old children and their parents
Insights
Hospital stays increase stress hormone excretion (adrenaline and noradrenaline) in children and parents. This stress response was similar across family members, despite higher baseline levels in children.
Area of Science:
- Endocrinology
- Psychophysiology
- Family Studies
Background:
- Urinary catecholamine and cortisol levels reflect physiological stress responses.
- Family dynamics and environmental changes can impact stress hormone excretion.
Purpose of the Study:
- To investigate urinary catecholamine and cortisol excretion in a family unit (children, mothers, fathers) during different environmental conditions (home vs. hospital).
- To compare stress hormone responses across family members and assess the impact of a hospital stay.
Main Methods:
- Longitudinal study tracking three-year-olds, mothers, and fathers.
- Measurement of urinary catecholamine (adrenaline, noradrenaline) and cortisol excretion.
- Comparison of hormone levels during night rest, one day at home, and one day at a hospital.
Main Results:
- Hospitalization significantly increased adrenaline and noradrenaline excretion in all family members compared to home levels.
- While children had higher baseline catecholamine excretion relative to body weight, the magnitude of the hospital-induced increase was similar across all ages.
- Cortisol levels tended to be elevated only in fathers at the hospital; mothers showed higher noradrenaline excretion than fathers at home and hospital.
Conclusions:
- Hospital environments induce comparable physiological stress responses in children and parents, as indicated by catecholamine excretion.
- Maternal stress response patterns may differ, potentially influenced by the specific challenges of the situation.
- Family members' stress hormone levels show a tendency towards positive correlation, though generally weak.
Abstract:
Urinary catecholamine and cortisol excretion was studied in a group of three-year-olds, their mothers and fathers during night rest, one day at home and one day at hospital. The stay in the hospital, which was part of a longitudinal study of the families, induced a pronounced rise in adrenaline excretion and a moderate increase in noradrenaline excretion in relation to the at-home level. Although the catecholamine excretion in relation to body weight was much higher in the children, the magnitude of the increase at the hospital was about the same in all the family members. The adrenaline excretion was also affected by the diverse conditions at the hospital and showed, for example, a marked decrease during lunch hour. The cortisol excretion at the hospital tended to be elevated only in fathers. On the average, mothers excreted about the same amount of adrenaline as the fathers at the hospital, but significantly more noradrenaline. In earlier studies males have shown a greater adrenaline output than females during achievement-demanding situations. The findings of this study were interpreted within the context of the specific challenge that the situation represented to the mothers. The mothers also excreted more noradrenaline in the at-home condition. Catecholamine and cortisol excretion levels within family members tended to be positively correlated, but the correlations were generally low.
