Clinical and Analytical Presentation of Central Precocious Puberty: A 20-Year Cross-Sectional Study

Abstract

Objectives − This study aims to compare the clinical and analytical presentation of Central precocious puberty (CPP), considering age.

Methods − An observational, cross-sectional study was conducted on children diagnosed with CPP at a level III hospital, between January 2002 and April 2022. Clinical, auxological, sociodemographic, laboratory, and imaging parameters were analyzed.

Results − Out of the 52 children studied, the majority were girls (N=44). The median age of puberty onset in girls was 6.79 years and the mean age at first consultation of 8.13 years, with a significantly lower age at hospital referral (7.65 years; P=0.045) compared to boys. Idiopathic etiology was predominant in both. In girls, breast development appeared at older mean ages (P=0.009), while pubic hair growth and accelerated growth were associated with younger ages at puberty onset (P=0.021; P=0.018, respectively). Basal and peak levels of gonadotropin hormones were higher in girls, although not statistically significant. In girls, age at puberty onset correlated negatively with standard deviation of body mass index (P=0.023), while age at first consultation correlated positively with bone age (P<0.001), and was associated with younger ages at Gonadotropin-Releasing Hormone stimulation test (P=0.020).

Conclusion − This study provides innovative and relevant findings that enhance understanding of CPP presentation according to age, thereby improving clinical management of this condition.
