Is Osteopenia Normal After Age 60?
Osteopenia is extremely common after age 60—affecting approximately 48% of postmenopausal women aged 60-94 years—but "common" does not mean "normal" or benign, as over half of all fragility fractures occur in individuals with osteopenia, not osteoporosis. 1
Prevalence and Clinical Significance
Osteopenia becomes increasingly prevalent with age but carries substantial fracture risk:
- Among women aged 60-94 years, 48% have osteopenia (T-score between -1.0 and -2.5), while only 14.5% have osteoporosis and 37.6% have normal bone density 1
- In elderly patients over 70 years scheduled for orthopedic surgery, 45.9% had osteopenia and 17.4% had osteoporosis 2
- Critically, 56.5% of all fragility fractures arise from women with osteopenia, compared to only 26.9% from those with osteoporosis 1
Why Osteopenia Matters Clinically
The population burden of fractures originates primarily in osteopenic individuals, not those with osteoporosis:
- Women with osteopenia plus a prior fracture have equivalent or greater fracture risk compared to women with osteoporosis alone 1
- Each standard deviation decrease in bone mineral density increases fracture risk by 65%, independent of diagnostic category 1
- Age and prior fracture independently contribute to fracture risk beyond bone density alone 1
Risk Stratification in Osteopenia
The American College of Physicians recommends individualized treatment decisions for osteopenic women ≥65 years based on fracture risk stratification:
- Women ≥65 years with severe osteopenia (T-score < -2.0) benefit most from treatment, with risedronate reducing fragility fractures by 73% compared to placebo 3
- Women with mild osteopenia (T-score between -1.0 and -1.5) have lower absolute benefit from treatment 3
- Additional risk factors that increase fracture risk include: lower body weight, smoking, family history of fractures, decreased physical activity, alcohol/caffeine use, low calcium/vitamin D intake, and corticosteroid use 3
Screening Recommendations
The 2025 USPSTF guidelines recommend screening for osteoporosis in:
- All women aged 65 years and older 4
- Postmenopausal women under 65 at increased fracture risk 4
- The transition from normal bone density to osteoporosis takes approximately 17 years for women with normal baseline BMD, but only 5 years for those with T-scores in the -1.50 to -1.99 range 4
Critical Clinical Pitfall
A major treatment gap exists: Among elderly patients with osteoporosis identified on screening, 95% were previously undiagnosed and untreated 2. This underdiagnosis is even more problematic in osteopenia, where the majority of fractures occur but treatment is often not considered 1.
The key clinical message: Osteopenia after age 60 is statistically common but should not be dismissed as "normal aging." Risk stratification using bone density, age, and clinical risk factors (particularly prior fracture) is essential to identify the substantial subset of osteopenic individuals who would benefit from intervention to prevent the majority of fragility fractures that occur in this population 3, 1.
