Assess osteoporosis risk from key clinical factors and lifestyle habits. Compare scores with sample data. Export summaries, inspect formulas, and understand each risk input.
This calculator organizes several common osteoporosis risk indicators into a single educational score. It is useful for quick review, comparison, and discussion when you want to examine how age, body size, bone density, lifestyle, and medical history may interact.
The page is designed for structured screening support rather than diagnosis. It can help identify strong risk drivers, highlight missing information such as a T-score, and create a cleaner summary for records, discussion, or follow-up planning.
Because osteoporosis assessment often depends on clinical context, medication history, DXA interpretation, and fracture history, the result should be treated as a guide. Use it to support questions for a clinician, not to replace professional evaluation.
This calculator uses an educational weighted scoring method. It is not FRAX and not a clinical diagnosis engine.
1) BMI formula
BMI = weight (kg) / [height (m)]²
2) Raw weighted score
Raw Score = Age Points + Sex Points + Menopause Points + BMI Points + Prior Fracture Points + Parent Hip Fracture Points + Smoking Points + Glucocorticoid Points + Rheumatoid Arthritis Points + Secondary Osteoporosis Points + Alcohol Points + Activity Points + Calcium Points + Vitamin D Points + T-Score Points
3) Normalized risk score
Risk Score = (Raw Score / 145) × 100, capped at 100
4) Estimated 10-year fragility risk
Estimated Risk = 1.5 + (Risk Score × 0.72) + age adjustment + prior fracture adjustment, capped at 85%
5) Risk bands
Low: below 25
Moderate: 25 to 44.9
High: 45 to 64.9
Very High: 65 and above
| Profile | Age | Sex | BMI | T-Score | Prior Fracture | Smoking | Estimated Band |
|---|---|---|---|---|---|---|---|
| Active adult with stable intake | 52 | Female | 24.6 | -0.8 | No | No | Low |
| Postmenopausal adult with osteopenia | 67 | Female | 21.9 | -2.0 | No | Yes | Moderate to High |
| Older adult with fracture history | 78 | Female | 18.9 | -2.8 | Yes | No | Very High |
It combines common osteoporosis risk indicators into an educational score. The output helps organize bone health factors, but it does not diagnose osteoporosis or replace a formal medical assessment.
No. This page uses a custom weighted model for structured review. FRAX uses validated population data and should be referenced separately when clinical decision-making requires it.
No. You can calculate a score without DXA data. However, including a femoral neck T-score usually improves the usefulness of the estimate.
Low body mass can be associated with lower bone reserve and higher fragility risk. The calculator adds more points when BMI is lower.
It refers to medical conditions or treatments that can weaken bone, such as endocrine disorders, malabsorption, chronic inflammatory disease, or long-term medication effects.
Yes. Men can still develop osteoporosis and fractures. The score includes sex as one factor, but the tool remains educational for both sexes.
Treat it as a planning aid rather than a diagnosis. It can help compare scenarios, highlight drivers, and support discussion with a clinician.
Seek medical review if you have a prior fragility fracture, very low T-score, long-term steroid use, frequent falls, or a high or very high result.
