Body proportions in precocious puberty.

L Martinez, M A Preece, D B Grant

    Acta Paediatrica Scandinavica
    |March 1, 1984
    PubMed
    Summary

    Children with precocious puberty exhibit greater trunk growth (sitting height) than leg growth (sub-ischial leg length). This difference is more pronounced in boys, indicating altered body proportion development.

    Area of Science:

    • Pediatric Endocrinology
    • Human Growth and Development
    • Anthropometry

    Background:

    • Precocious puberty involves early onset of secondary sexual characteristics, potentially affecting growth patterns.
    • Understanding body proportion development in precocious puberty is crucial for clinical assessment.

    Purpose of the Study:

    • To investigate and compare the growth of sitting height (SH) and sub-ischial leg length (SLL) in children with precocious puberty.
    • To determine if trunk or leg growth is disproportionately affected in this condition.

    Main Methods:

    • Measurements of sitting height (SH) and sub-ischial leg length (SLL) were taken.
    • Standard deviation scores (SDS) for SH and SLL were calculated relative to chronological and bone age.
    • Data were analyzed for 10 boys and 16 girls diagnosed with precocious puberty.

    Main Results:

    • In most patients, sitting height (SH) showed higher standard deviation scores (SDS) than sub-ischial leg length (SLL).
    • This disparity between SH and SLL was observed across both genders but was more significant in boys.
    • Two female patients were exceptions, showing higher SLL scores than SH scores.

    Conclusions:

    • Trunk growth (SH) generally exceeds leg growth (SLL) in precocious puberty.
    • Boys with precocious puberty demonstrate a more pronounced trunk-to-leg growth imbalance compared to girls.
    • These findings highlight specific anthropometric alterations in precocious puberty impacting body proportions.
