Objective:
To evaluate the ability of women affected by functional hypothalamic secondary amenorrhea (FHSA) or polycystic ovary syndrome (PCOS) to adapt to stress.
Design:
Controlled clinical study.
Setting:
University hospital.
Patient(S):
Thirty-one patients affected by FHSA, 29 patients with PCOS, and 30 eumenorrheic women.
Intervention(S):
The subjects took the Stroop Color Word (Stroop CW) test and underwent blood sampling.
Main Outcome Measure(S):
Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and serum cortisol levels.
Result(S):
The healthy controls had better Stroop CW scores than patients with FHSA. Serum cortisol levels significantly increased during Stroop CW with respect to the baseline in patients with FHSA or PCOS but not in the healthy controls. The SBP, DBP, and HR of the controls as well as SBP and DBP of patients with PCOS were significantly higher than those measured in patients with FHSA both at the baseline and during Stroop CW.
Conclusion(S):
Patients with FHSA do not cope as well as healthy patients, and their autonomic response to stress is worse than both controls and patients with PCOS.
