10-Year Fracture Risk Calculator

The American Bone Health Fracture Risk Calculator™ Version 3.0 estimates fracture risk for women and men over age 45.

Do you have a question about how the Fracture Risk Calculator works for you?
Find answers on the Calculator Frequently Asked Questions (FAQs) page.

General questions about you

  • 1
  • How old are you? (nearest year)

    Enter age in whole years, rounding to the nearest year. Age must be greater than or equal to 45 years.

General questions about you

  • 2

    Are you a man or a woman?

    Enter your gender at birth

General questions about you

  • 3
  • What race and ethnicity do you most consider fits you?

General questions about you

  • 4

    What is your current height?

    Enter height in feet and inches. Height must be between 4 feet 8 inches and 6 feet 4 inches. If you are shorter or taller, enter the minimum or maximum, knowing that the results will be an estimate.

General questions about you

  • 5

    What is your current weight?

    Enter weight in whole pounds, rounding to the nearest pound. Weight must be between 70 and 300 pounds. If you are thinner or heavier, enter the minimum or maximum, knowing that the results will be an estimate.

General questions about you

  • 6

    Have you ever had a bone density test on a table machine?

General questions about you

  • 7
  • The ABH FRC will give results with or without a bone density test score. If you want to add your bone density result, enter your femoral neck T-score (include the minus (-) sign if it is on the report). If you do not know your Femoral Neck T-score, leave this field blank and click next.

    Enter your Femoral Neck T-score as a decimal number. Be sure to use the minus sign if the T-score is negative.


General questions about you

Factors that can increase your risk

  • 9

    Do you currently smoke tobacco?

    There is a direct relationship between tobacco and decreased bone density, whether it’s the smoking or the other risk factors of smokers, such as, being thinner, drinking more alcohol, being less physically active, and having a poor diet. Women who smoke go through menopause at a younger age than women who don’t smoke.

    Enter "Yes" if you currently smoke any quantity of cigarettes, cigars, or pipes. Enter "No" if you have never smoked or have quit.

Factors that can increase your risk

  • 10

    Do you regularly have >2 alcoholic drinks a day?

    Excess alcohol has a negative effect on bone density, fracture, and fracture healing. Too much alcohol interferes with calcium and vitamin D absorption, affects the liver, and decreases estrogen. Cortisol and parathyroid level is increased in alcoholics and leads to calcium malabsorption.

    Enter "Yes" if you drink 3 or more alcoholic beverages a day. One drink is 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of distilled spirits (80 proof).

Factors that can increase your risk

  • 11

    Have you ever taken prednisone or steroid pills for 3 months or longer? Or very high doses of inhaled steroids for extended periods of time?

    Inflammatory diseases like Lupus and Rheumatoid Arthritis that require more than 5 milligrams/day of steroids cause rapid bone loss by affecting the bone remodeling process.

    Enter “Yes” if you have ever taken a minimum of 5 milligram dose of Prednisone or steroids for 3 months or longer, or if you have taken very high doses of inhaled steroids regularly (> 400 micrograms/day budenoside or beclomethasone or > 200 micrograms/day fluticasone).

    Enter “No” if you have used creams, gels, or inhaled steroids intermittently.

Factors that can increase your risk

  • 12

    Do you have rheumatoid arthritis?

    Inflammation around the joints causes bone loss; pain leads to reduced activity.

    Enter "Yes" if you have Rheumatoid Arthritis. Enter "No" if you have other kinds of arthritis, such as osteoarthritis.

Medical conditions that can increase your risk

  • 13

    Have you been diagnosed with diabetes? (type 1 or type 2)

    Low insulin levels in childhood or adolescence may lead to weaker bones and an increased risk of fractures in adulthood. Excess blood sugar affects collagen in the bones, making them brittle and more likely to break. Diabetes medicines also increase fracture risk. You are also at an increased risk of falling and fracturing because of blood sugar levels, declining vision, associated peripheral neuropathy and nerve damage.

Fracture history

  • 15

    Has your mother or father had a hip fracture?

    Genetics is one of the most important factors that determine your risk of fractures. About 60% of your bone density is a result of genetics. Family history of broken bones means you are at higher risk.

Fracture history

  • 16

    Have you broken bones with little impact, such as a trip or fall from level ground, since age 45?

    if you break any bone (except fingers and toes) from a trip or fall on level ground after age 45, you are twice as likely to break another bone! If you have a spine fracture, you are four times as likely to have another spine fracture.

Fracture history

  • 17

    Have you been told that you have a spine fracture?

    A doctor told you or it was reported on an x-ray?
