Osteoporosis Risk Calculator - FRAX Score Calculator

Understanding Your Osteoporosis Risk: A Guide to the FRAX Score Calculator

Osteoporosis is a silent disease that weakens bones, increasing the risk of fractures—especially in the hip, spine, and wrist. Early detection and risk assessment are crucial for prevention and treatment. The FRAX (Fracture Risk Assessment) Score Calculator is a globally recognized tool that estimates your 10-year probability of experiencing a major osteoporotic or hip fracture.

In this article, we’ll break down:

• Key terms used in the FRAX calculator

• Why these factors matter in osteoporosis risk assessment

• How to interpret your FRAX score results

• How the calculator works

By the end, you’ll have a clear understanding of how to use this tool to assess your bone health risk.

Key Terms in the FRAX Calculator and Their Importance

1. Gender

• Why it matters: Women are at higher risk of osteoporosis due to lower peak bone mass and hormonal changes after menopause.

2. Age

• Why it matters: Bone density decreases with age, increasing fracture risk. The FRAX calculator is designed for individuals aged 40–90.

3. Weight & Height (BMI Calculation)

• Why it matters: Low body weight (BMI < 20) is linked to higher fracture risk, while obesity may offer some protection (but comes with other health risks).

4. Previous Fracture (After Age 40)

• Why it matters: A prior fracture, especially due to minor trauma, strongly predicts future fractures.

5. Parent with Hip Fracture

• Why it matters: Genetics play a role in bone density and fracture susceptibility.

6. Current Smoker

• Why it matters: Smoking reduces bone formation and accelerates bone loss.

7. Long-Term Glucocorticoid Use (≥5mg prednisolone for ≥3 months)

• Why it matters: Steroids weaken bones by decreasing calcium absorption and bone formation.

8. Rheumatoid Arthritis

• Why it matters: Chronic inflammation and steroid use in RA patients increase osteoporosis risk.

9. Secondary Osteoporosis (Conditions like Diabetes, Hyperthyroidism, etc.)

• Why it matters: Certain diseases and medications contribute to bone loss.

10. Alcohol Intake (≥3 Units/Day)

• Why it matters: Excessive alcohol interferes with bone remodeling and calcium balance.

11. Femoral Neck BMD (Bone Mineral Density – Optional Input)

• Why it matters: A DEXA scan measures bone density, providing the most accurate fracture risk prediction when included.

Interpreting Your FRAX Score Results

After entering your details, the FRAX calculator provides two key percentages:

1. Major Osteoporotic Fracture Risk (10-Year Probability)

• Low Risk (<10%): Minimal intervention needed, but maintain bone-healthy habits.

• Moderate Risk (10–20%): Lifestyle changes (calcium, vitamin D, exercise) and possible medication discussion with a doctor.

• High Risk (>20%): Strongly consider medical treatment to prevent fractures.

2. Hip Fracture Risk (10-Year Probability)

• Low Risk (<3%): Low likelihood, but monitor bone health.

• Moderate Risk (3–6%): Increased vigilance and possible preventive measures.

• High Risk (>6%): High chance of hip fracture—medical intervention recommended.

Note: If you didn’t input BMD, the score is an estimate. A DEXA scan provides a more precise assessment.

How the FRAX Calculator Works

The FRAX algorithm, developed by the World Health Organization (WHO), combines clinical risk factors with (optional) bone density data to predict fracture probability.

Steps to Use the Calculator:

1. Enter basic details (age, gender, weight, height).

2. Select risk factors (smoking, alcohol, medical conditions).

3. Optionally add BMD (if you have a DEXA scan result).

4. Click "Calculate" to see your 10-year fracture risk.

Why This Tool Is Useful:

• Personalized risk assessment (not just age-based).

• Helps guide treatment decisions (lifestyle changes vs. medication).

• Encourages early prevention before fractures occur.

Final Thoughts

Understanding your osteoporosis risk empowers you to take proactive steps—whether through diet, exercise, or medical treatment. Use the FRAX calculator above to estimate your risk and discuss the results with your healthcare provider for personalized advice.
