Abstract :Aims: Our objective is to explore changes in body fat distribution and muscle strength among a cohort of girls with idiopathic central precocious puberty (ICPP) undergoing the gonadotropin-releasing hormone analogs (GnRHa) therapy. Methods: A total of 50 patients who were newly diagnosed with ICPP and treated with GnRHa were included in the study. Patients were investigated at baseline, 6th months and 12th months. Results: Body-mass index (BMI) standard deviation score (SDS) was similar throughout the treatment duration. The percentage of body fat (PBF) increased from 24.2±5.1% at the beginning to 26.3±5.3% at the 6th month and to 27.7±5.43% at the 12th month (p 97th p (p=0.005). Conclusion: Over the one-year duration of GnRHa treatment, no increase was observed in BMI SDS. While PBF increased, a decrease was noted in LBM percentage. Despite the decrease in LBM percentage, since LBM increased over the course of treatment, an increase in muscle strength was observed under GnRHa therapy. Additionally, the alteration in PBF during GnRHa treatment exhibited variations based on the initial PBF status.
