    This study tracked pubertal development in Swedish children, finding typical timing and patterns. Clinical exams are efficient for assessing secondary sex characteristics, with specific methods recommended for boys.

    Area of Science:

    • Pediatrics
    • Human Growth and Development
    • Endocrinology

    Background:

    • Pubertal development is a critical phase in human growth.
    • Understanding the timing and patterns of pubertal changes is essential for monitoring child health.
    • Previous studies provide benchmarks for pubertal development in various populations.

    Purpose of the Study:

    • To investigate the pubertal development of Swedish urban children.
    • To compare clinical examination with whole-body photography for assessing secondary sex characteristics.
    • To establish normative data for pubertal timing and progression.

    Main Methods:

    • Prospective longitudinal study of 212 randomly selected Swedish urban children.
    • Assessment of pubertal changes using clinical examination and whole-body photography.

  • Comparison of the two methods for reliability and resource efficiency.

    • Main Results:

    • Pubertal timing and patterns align with contemporary studies of Swedish children.
    • Clinical examination is less resource-intensive and has psychological benefits.
    • Boys benefit from testicular volume estimation (orchidometry) alongside clinical exams; girls show similar precision between methods.

    Conclusions:

    • The study sample is representative of contemporary Swedish children.
    • Clinical assessment is a viable method for tracking pubertal development.
    • Early pubertal changes occur before age 9 in girls and before age 10 in boys, with girls typically developing earlier.
