ABSTRACT
OBJECTIVE:
To investigate the cardiac autonomic nerve function in girls with idiopathic central precocious puberty (ICPP).METHODS:
A total of 66 girls with ICPP were enrolled, among whom 36 were obese and 30 were not obese. A total of 68 age-matched healthy girls (normal controls) and 51 girls with simple obesity were enrolled as controls. All the subjects underwent 24-hour ambulatory electrocardiography, and deceleration capacity of heart rate (DC), acceleration capacity of heart rate (AC), and heart rate variability (HRV), and body mass index (BMI) were compared between groups.RESULTS:
Compared with the normal control group, the ICPP group had significantly lower DC, standard deviation of normal-to-normal R-R intervals (SDNN), standard deviation of the average normal-to-normal intervals (SDANN), root mean square of successive differences (RMSSD), and high-frequency power (HF) and significantly higher AC and BMI. The ICPP group had significantly lower RMSSD and BMI than the simple obesity group (P<0.05). Compared with the ICPP girls without obesity, those with obesity had significantly lower DC, RMSSD, and HF and significantly higher AC and BMI (P<0.05).CONCLUSIONS:
Cardiac autonomic dysfunction is seen in girls with ICPP, especially those with obesity, mainly presenting with reduced vagal tone.
