Summary

Puberty is a critical transition from childhood to adulthood. Over the past two decades, studies worldwide have shown a trend toward earlier pubertal onset, which is thought to be influenced by factors such as lifestyle changes, improved nutrition, and environmental exposures. However, there is currently a lack of local data regarding the timing of puberty in Upper Egypt.

The main purpose of this observational study is to determine the average age at which puberty begins among girls living in the Asyut governorate, Egypt. The study specifically focuses on thelarche (breast development), which is the earliest clinical sign of pubertal onset. Additionally, the study aims to identify possible genetic, demographic, physical, and environmental factors that might influence the timing of this developmental milestone.

The study will include approximately 600 girls aged 6 to 13 years from both urban and rural areas of Asyut. Researchers will collect data during a single visit using a structured questionnaire administered through personal interviews with the participants and their parents or caregivers. The questionnaire will gather information on early life history, family history, dietary habits, physical activity, sleep patterns, screen time, stress, environmental exposures, and pubertal history. Researchers will also take basic physical measurements, including height, weight, and waist circumference to calculate Body Mass Index (BMI).

Participants will not be exposed to any invasive procedures or additional clinical risks beyond their routine care. The findings will help establish local reference values for pubertal development and support evidence-based adolescent health strategies in Egypt.
