Summary
Bone density peaks around age 40 in women, declining thereafter. Menopause significantly accelerates bone loss, increasing fracture risk, highlighting bone density measurement
Area of Science:
- Gerontology
- Osteoporosis Research
- Bone Metabolism
Context:
- Investigated bone mass changes in 434 healthy women aged 20-65.
- Utilized single-photon absorptiometry (SPA) for bone density measurements.
- Focused on radial bone sites (distal and mid-radius).
Purpose:
- To study bone density and related factors in women across different age groups.
- To determine the age of peak bone density and the onset of bone loss.
- To assess the impact of menopause and aging on bone density and fracture risk.
Summary:
- Bone density in women peaks around age 40, with loss beginning around 45.
- Menopause accelerates bone loss, particularly in trabecular bone, more than aging.
- Postmenopausal women with fractures exhibit lower bone density than those without.
Impact:
- Bone density measurement can predict osteoporotic fracture risk.
- Identifies menopause as a critical factor in accelerated bone loss.
- Provides insights into age-related and menopausal bone changes.
