Bone Density / Osteoporosis Risk Screener
Quick answer
A simple risk-factor screener that counts how many well-established osteoporosis risk factors apply to you — age, menopause, family history, smoking, low body weight and long-term steroid use. It is a conversation-starter for discussing bone health with a doctor, not a diagnosis and not a measure of bone density.

How the count is built
Start at 0 and add 1 for each marker present:
Age 65+ (women) or 70+ (men)
Post-menopausal (women)
Family history of osteoporosis or hip fracture
Current smoker
Low body weight (BMI under ~19)
Long-term oral steroid use (e.g. prednisone)
Tiers: 0–1 lower · 2–3 moderate · 4+ higher
The check list follows the classic NOF/BHOF risk-factor list. It deliberately does not produce a percentage risk or a T-score — FRAX is a licensed clinical algorithm and is not replicated here.
Worked example
- 1
A 58-year-old woman, post-menopausal, whose mother broke a hip. Non-smoker, BMI 21, no steroids.
- 2
Markers present: post-menopause (+1) and family history (+1) = 2 factors.
- 3
Tier: moderate risk factor count — a good topic to raise at her next check-up.
- 4
No percentage or T-score is produced, because only a DEXA scan can measure bone density.
Interpreting your risk tier
| Your result | Category | What it means |
|---|---|---|
| 0–1 factors | Lower risk factor count | Few typical osteoporosis markers present. Keep up weight-bearing exercise, adequate calcium and vitamin D, and avoid smoking. |
| 2–3 factors | Moderate risk factor count | A few known risk factors are present — consider discussing bone health with your doctor. |
| 4+ factors | Higher risk factor count | Several known risk factors are present — a bone density (DEXA) scan discussion with your doctor is recommended. |
This is not a diagnostic tool and does not measure bone density. Only a DEXA scan ordered by a doctor can diagnose osteoporosis. The tier only reflects how many known risk factors are present — it is not a percentage, clinical score or T-score.
