The WHO Fracture Risk Assessment Tool (FRAX) is a widely used calculator to estimate the 10-year probability of major osteoporotic fractures in postmenopausal women and men over 50 years old. This calculator provides a personalized assessment of fracture risk based on demographic, clinical, and lifestyle factors.
What is the WHO Fracture Risk Assessment Tool (FRAX)?
The FRAX tool was developed by the World Health Organization (WHO) and the International Osteoporosis Foundation (IOF) to help healthcare providers and patients assess fracture risk. It's based on extensive clinical data and is used in many countries, including the USA.
The FRAX tool is not a diagnostic tool but rather a risk assessment tool. It should be used in conjunction with clinical examination and other diagnostic tests.
Key Features of FRAX
- Estimates 10-year probability of major osteoporotic fractures
- Considers demographic factors (age, sex, ethnicity)
- Incorporates clinical factors (bone mineral density, prior fractures)
- Accounts for lifestyle factors (smoking, alcohol, physical activity)
- Provides risk categories (low, moderate, high)
Types of Fractures Assessed
FRAX assesses risk for several types of fractures:
- Hip fracture
- Major osteoporotic fracture (hip, spine, or wrist)
- Clinical fracture (any fracture that requires medical attention)
How to Use the WHO Frac Calculator USA
Using the WHO Frac Calculator USA is straightforward. Simply enter your information in the calculator on the right side of this page, then click "Calculate" to get your fracture risk assessment.
Required Information
The calculator requires the following information:
- Age
- Sex
- Ethnicity (White, Black, Asian, or Other)
- Height
- Weight
- Smoking status
- Alcohol intake
- Physical activity level
- Previous fracture history
- Bone mineral density (if available)
Interpreting the Results
After entering your information, the calculator will provide:
- 10-year probability of hip fracture
- 10-year probability of major osteoporotic fracture
- 10-year probability of clinical fracture
- Risk category (low, moderate, high)
Formula: The FRAX tool uses a complex algorithm that combines demographic, clinical, and lifestyle factors to estimate fracture risk. The exact formula is proprietary but has been validated through extensive clinical research.
How to Interpret Your Results
Understanding your FRAX results is crucial for making informed decisions about your bone health. Here's what each risk category means:
Low Risk (≤10%)
Your fracture risk is relatively low. This doesn't mean you can't have a fracture, but it suggests you're at lower risk than the average person your age. Regular monitoring is still recommended.
Moderate Risk (10-20%)
You have a moderate risk of fracture. This suggests you may benefit from lifestyle modifications, such as increased calcium and vitamin D intake, weight-bearing exercise, and avoiding smoking.
High Risk (>20%)
A high fracture risk indicates you're at significant risk of osteoporosis-related fractures. You should consider discussing treatment options with your healthcare provider, which may include medication, lifestyle changes, or other interventions.
Remember that FRAX provides an estimate of risk, not a definitive diagnosis. Always consult with your healthcare provider for personalized advice.
