    Summary

    Bone loss accelerates with aging and certain diseases. Females experience earlier bone loss than males, while conditions like steroid therapy and chronic renal failure significantly increase bone volume loss.

    Area of Science:

    • Osteology
    • Gerontology
    • Pathology

    Background:

    • Bone volume loss is a significant health concern, particularly with aging and various diseases.
    • Understanding the factors influencing bone density is crucial for developing effective interventions.

    Purpose of the Study:

    • To investigate the morphologic measurement of bone volume loss in relation to aging and diverse pathological conditions.
    • To compare the patterns of bone loss between males and females and across different disease groups.

    Main Methods:

    • Analysis of lower lumbar vertebrae from 905 autopsy cases.
    • Calculation of trabecular bone dimensional ratios using a video image processor (VIP).
    • Comparison of bone volume loss across control, aging, and various disease cohorts.

    Main Results:

    • Females exhibit bone loss starting in the fifth decade, progressing rapidly, while males show gradual loss from the sixth decade.
    • High bone volume loss was observed in patients undergoing high-dose steroid hormone therapy and those with chronic renal failure.
    • Malignant tumors, liver cirrhosis, and heavy drinkers showed considerable bone loss in younger individuals, with no difference in older individuals compared to controls.
    • Diabetes mellitus demonstrated a unique pattern of high bone volume in younger individuals and accelerated loss in older individuals.

    Conclusions:

    • Bone loss is accelerated by the combined effects of aging and various pathological factors.
    • Specific diseases and treatments, such as steroid therapy and chronic renal failure, significantly exacerbate bone volume loss.
    • Diabetes mellitus presents a distinct pattern of bone volume changes across the lifespan.
