Abstract:
Objective To analyse the relative factors of the linear growth velocity(GV)in girls with central precocious puberty(CPP)during gonadotropin-releasing hormone analog(GnRHa)therapy,and to investigate the factors affecting the height gain during two-year GnRHa treatment.Methods In 86 girls aged (8.04?1.28)years with CPP treated with GnRHa for more than 2 years,the data including target height,age of onset,pubertal course,chronological age,bone age,linear GV,serum estradiol level and mature index of vaginal smear were analyzed,then the correlations and stepwise regression were performed.Results During GnRHa therapy,GV decreased year by year.The GV in the second year(GV_(2nd))was negatively correlated with the age of onset,bone age(BA_0,BA_2)and chronologic age(CA_0,CA_2)at the onset and by the end of the first year of GnRHa therapy(r=-0.37,-0.59,-0.57,-0.51 and-0.52,respectively,all P
