Recent research has observed a rise in the age at which puberty begins, both in the United States and Europe, with a noted increase in cases of precocious puberty that varies by region. Early puberty can lead to early menstruation, shorter adult height, and psychological effects. Due to limited studies and data, the reasons behind these trends remain unclear, though environmental factors such as endocrine disruptors and nutrition are considered possible contributors. This study aims to create a national observatory to monitor early and advanced puberty in collaboration with pediatric endocrinologists to improve epidemiological understanding. The observatory will focus on identifying cases of precocious and advanced puberty in private healthcare settings. It will include groups with suspected early puberty (girls under 8 years, boys under 9 years) and advanced puberty (girls aged 8 to under 10 years, boys aged 9 to under 11 years) based on the appearance of first pubertal signs. A control group of children without signs of puberty, matched by age and sex, will also be included. The study intends to enroll at least 75% of eligible patients and collect at least 80% of the main data. Participants will have consultations with pediatric endocrinologists who will collect clinical data over a period of up to 48 months. The study will monitor data completeness and recruitment rates, aiming to maintain high-quality data collection throughout the observation period. The observatory seeks to provide a reliable, detailed field approach to supplement existing epidemiological information on pubertal development.
