Background Central precocious puberty (CPP) is a common endocrine disease in children, which shows an increasing trend year by year in recent years. It can be divided into fast-progressing central precocious puberty (RP-CPP) and slow-progressing central precocious puberty (SP-CPP) through pubertal development. RP-CPP has great harm, but it is difficult to distinguish it from SP-CPP in early clinical stage, mainly relying on the progress of adolescent development and bone age during follow-up. At present, there is a lack of effective laboratory indicators to predict RP-CPP. Objective To investigate the relationship between luteinizing hormone (LH) /follicle-stimulating hormone (FSH) ratio and pubertal development. Methods CPP girls aged 4-10 years old (n=380) admitted to the Children's Hospital Affiliated to Zhengzhou University from January 2020 to May 2022 were regression selected and divided into RP-CPP group (n=130) and SP-CPP group (n=250 cases) according to indicators such as puberal development process. Clinical characteristics of the two groups were compared and analyzed. Univariate and multivariate Logistic regression analysis of the influencing factors of RP-CPP was performed, and ROC curve of LH/FSH ratio on the predictive value of RP-CPP was drawn. Results The height, weight, BMI, IGF-1, difference between bone age and actual age, bilateral ovarian volume, LH base value, estradiol level, LH base value /FSH base value, and LH peak /FSH peak value of girls in RP-CPP group were all higher than those in SP-CPP group, with statistical significance (P
