Bone mineral in Vilcabamba, Ecuador.

R B Mazess

    AJR. American Journal of Roentgenology
    |April 1, 1978
    PubMed
    Summary

    Elders in Ecuador show fewer fractures and spinal issues, despite having 15% lower bone mineral content than US whites. This suggests longevity isn't linked to higher bone mass or reduced age-related bone loss.

    Area of Science:

    • Gerontology
    • Bone Densitometry
    • Population Health

    Background:

    • Ecuadorian populations exhibit remarkable longevity.
    • A low incidence of fractures and spinal curvature is observed in elderly Ecuadorians.
    • Understanding the skeletal health of this population is crucial for aging research.

    Purpose of the Study:

    • To investigate bone mineral content in an Ecuadorian population.
    • To determine if higher bone mass explains the rarity of skeletal issues in elderly Ecuadorians.
    • To explore the relationship between bone density, aging, and skeletal health in diverse populations.

    Main Methods:

    • Photon absorptiometry was used to measure bone mineral content of the radius.
    • Bone mass was statistically adjusted for age, height, weight, and bone width.
    • Data were compared to reference values from U.S. white populations.

    Main Results:

    • Adjusted bone mass in the Ecuadorian population was 15% lower than in U.S. whites.
    • The findings indicate that high bone mass does not account for the rarity of skeletal problems.
    • Age-related bone loss does not appear to be diminished in this group compared to U.S. whites.

    Conclusions:

    • The low incidence of fractures and spinal curvature in elderly Ecuadorians is not attributable to superior bone mineral content.
    • Skeletal health in aging populations may be influenced by factors beyond bone density.
    • Further research is needed to identify the determinants of skeletal resilience in long-lived populations.
