Differences in hormonal responses to preoperative emotional stress between preschool and school children
Insights
Children
Area of Science:
- Pediatric endocrinology
- Child psychology
- Stress response research
Background:
- Children's behavior under emotional stress varies by age.
- Preoperative stress impacts children differently based on developmental stage.
Purpose of the Study:
- To investigate how age influences hormonal reactions to preoperative emotional stress in boys.
- To compare stress hormone levels in preschool versus school-aged boys.
Main Methods:
- Measured catecholamines (adrenaline, noradrenaline) and cortisol in 56 healthy boys before surgery.
- Assessed anxious behavior in relation to hormonal concentrations.
- Compared responses between preschool (3-5 years) and school-aged (6-11 years) boys.
Main Results:
- Preschool boys with anxiety showed significantly higher cortisol, adrenaline, and noradrenaline levels.
- School-aged boys with anxiety had elevated cortisol levels, but not adrenaline or noradrenaline.
- Age-dependent differences in hormonal stress responses were observed.
Conclusions:
- Hormonal responses to preoperative stress in boys are age-dependent.
- Preschool boys exhibit a broader hormonal stress response compared to school-aged boys.
- Anxiety's association with specific stress hormones differs between age groups.
Background:
The behavior of children under emotional stress differs according to whether they are of preschool or school age.
Methods:
To examine the effect of age on hormonal responses to preoperative emotional stress, we measured the concentrations of catecholamines (adrenaline and noradrenaline) and cortisol in 56 healthy boys before surgery.
Results:
Among preschool boys (3-5 years old), those showing anxious behavior showed significantly higher cortisol, adrenaline, and noradrenaline concentrations in the blood circulation than those not showing such behavior (P < 0.0001, P < 0.0001 and P < 0.005, respectively). However, among the schoolboys (6-11 years old), anxiety was associated only with the cortisol concentration (P < 0.01).
Conclusion:
Hormonal responses to preoperative emotional stress in preschool boys differ from those in schoolboys.
