Osteoporosis Screening: The Guidelines, Explained
Fragility fractures — a wrist from a stumble, a hip from a sneeze — are osteoporosis announcing itself after decades of silence. Screening exists to hear the announcement earlier.
Osteoporosis screening with DXA is recommended for all women 65 and older, and for younger adults with risk factors such as prior fragility fractures, early menopause, long-term steroids, or high FRAX scores. Men are screened at 70+ or with risk factors. The 15-minute, near-zero-radiation DXA scan sets the baseline; results steer treatment and follow-up intervals.
Who should be screened for osteoporosis?
- All women 65 and older — the universal recommendation
- Younger women with risk factors: prior fragility fracture, family history of hip fracture, early menopause, low body weight, smoking, heavy alcohol, long-term steroids, rheumatoid arthritis
- Men 70 and older, and younger men with the risk factors above
The FRAX tool converts risk factors into fracture probability; scores crossing thresholds earn earlier screening.
What happens during DXA screening?
You lie on a padded table while a scanning arm passes over your hip and lower spine — 15 minutes, no tunnel, no needles, radiation roughly equal to a day of natural background. The result is a T-score: normal above −1.0, osteopenia −1.0 to −2.5, osteoporosis −2.5 and below. The full experience is in our DXA guide.
When should screening start earlier than 65?
When risk factors multiply: a fragility fracture at any age is an automatic trigger; so is five-plus years of corticosteroids, early menopause before 45, a parent who fractured a hip, body mass under about 127 pounds, or a FRAX score crossing national thresholds. The logic is simple — DXA is cheap and harmless, and the treatments work best before the first fracture, not after.
How often should DXA be repeated?
If normal: typically every 2–5 years depending on risk. On treatment: follow-up intervals follow your doctor's plan, often 1–2 years to confirm response, then longer. One practical rule matters more than the calendar: repeat scans at the same facility on the same machine, because scanner differences can mimic change. Stability on consistent equipment is the strongest reassurance.
Frequently asked questions about osteoporosis screening
At what age should I get a bone density test?
Women at 65, men at 70 — earlier with risk factors like prior fragility fracture or long-term steroids.
Is DXA screening covered by insurance?
Yes — Medicare and most plans cover screening DXA for eligible patients, typically every two years.
What is a fragility fracture?
A fracture from a fall at standing height or less — a wrist from a stumble signals weakened bone and triggers screening regardless of age.
What is the FRAX score?
A fracture-risk calculator combining risk factors with (optionally) femur-neck BMD into a 10-year probability.
Can osteoporosis be reversed on DXA?
T-scores can improve meaningfully on treatment, though the primary goal is preventing fractures — the number is the means, not the end.
Do men need osteoporosis screening?
Yes — at 70+, or earlier with risk factors; a quarter of fragility fractures happen to men.
