Area of Science:

  • Pediatrics
  • Bone Health
  • Radiology

Background:

  • Establishing normative data for bone mineral content (BMC) is crucial for assessing pediatric bone health.
  • Dual Photon Absorptiometry (DPA) is a recognized method for measuring BMC in growing individuals.

Purpose of the Study:

  • To establish normal bone mineral content (BMC) values in healthy growing children.
  • To analyze age- and sex-specific differences in BMC during childhood and adolescence.
  • To develop regression equations for estimating BMC in pediatric populations.

Main Methods:

  • Bone mineral content (BMC) was measured in 140 healthy children (49 girls, 91 boys) using Dual Photon Absorptiometry (DPA).
  • Measurements were taken at the L2-L4 vertebral level of the spine.

  • Data were stratified by age and sex to identify developmental trends.

    • Main Results:

    • BMC significantly increased with age in both sexes.
    • Children aged 7-10 years showed similar BMC levels regardless of sex.
    • Female children demonstrated significantly higher BMC than males at ages 12-13 years.
    • Regression equations were derived: Female BMC = 0.38 + 0.021 x age; Male BMC = 0.45 + 0.017 x age.

    Conclusions:

    • Age- and sex-specific reference ranges for pediatric BMC are established.
    • The derived regression equations can aid in estimating BMC in children.
    • These findings contribute to the understanding of normal bone development in children.
