Compact bone mineral density of the normal human radius
Acta Radiologica: Oncology, Radiation, Physics, Biology
|January 1, 1978
Summary
Bone mineral density in the radius remains stable until age 50, with women having slightly higher bone density than men. After 50, women experience a greater decline in bone mineral density.
Area of Science:
- Gerontology
- Orthopedics
- Radiology
Background:
- Bone mineral density (BMD) is a key indicator of bone health and fracture risk.
- Age-related changes in BMD differ between sexes, impacting skeletal integrity.
Purpose of the Study:
- To assess age- and sex-related changes in compact bone mineral density.
- To establish normative data for bone mineral density in a healthy adult population.
Main Methods:
- Roentgen ray photodensitometry was used to measure bone mineral density.
- The proximal radius was analyzed in 292 men and 302 women aged 20–90 years.
Main Results:
- Bone mineral density showed no significant change between ages 20 and 49.
- Women exhibited slightly higher bone mineral density than men in younger age groups.
- After age 50, bone mineral density decreased more substantially in women compared to men.
Conclusions:
- Bone mineral density is maintained until mid-adulthood, after which it declines.
- Sex-specific differences in bone mineral density decline become more pronounced after age 50, highlighting potential sex-based osteoporosis risks.
