Risk calculators and risk factors for Osteoporosis screening |
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Cafer Zorkun, M.D., Ph.D. [2], Raviteja Guddeti, M.B.B.S.[3]
Overview
Today, risk of fracture due to osteoporosis is threatening one out of two postmenopausal women and also one out of five older men. The 10-year risk for any osteoporosis-related fractures in 65-year-old white woman with no other risk factor is 9.3%. Upon the guidelines of USPSTF, all women ≥ 65 years old along with women < 65 years old with high risk of fracture are target of screening for osteoporosis; but there is not any recommendation to screen men for the disease. There are two major methods, that is suggested to use for screening osteoporosis: dual energy x-ray absorptiometry (DXA) of both hip and lumbar spine bones, and quantitative ultrasonography of the calcaneus.
Screening
Risk assessment
- Today, risk of fracture due to osteoporosis is threatening one out of two postmenopausal women and also one out of five older men. Leading ethnicity involved in osteoporosis is white. The rate of osteoporosis is higher in elderly. The 10-year risk for any osteoporosis-related fractures in 65-year-old white woman with no other risk factor is 9.3%. The 10-year probability of hip fracture can be estimated by the FRAX tool based on the presence or absence of clinical risk factors in addition to the bone mineral density (BMD) at the femoral neck.
Screening criteria
- The US Preventive Services Task Force (USPSTF) divides the population to three groups, categorize their need to be screened for osteoporosis; they include:
- Women of 65 years and older, without any fracture history or pathological reason for osteoporosis
- Women of less than 65 years, with 10-year fracture risk of not less than a 65-year-old white woman (who has not any other risk factor)
- Men with no osteoporosis history
- Upon the guidelines of USPSTF, the former two groups (women) are target of screening for osteoporosis; but there is not any recommendation to screen the third group (men) for the disease.[1]
- Prior USPSTF recommendations from 2002 were include:
- All women of 65 and older should be screened by bone marrow densitometry.[2]
- The USPSTF recommends screening women aged 60-64 years old, who are at increased risk of fracture. The most significant risk factor for indicating an increased probability of having osteoporosis is lower body weight (< 70 kg).
- Clinical prediction rules are available to guide selection of women for screening. The Osteoporosis Risk Assessment Instrument (ORAI) may be the most sensitive strategy.[3]
- Regarding the screening process for men, a cost-analysis study suggests that screening may be "cost-effective for men with a self-reported prior fracture beginning at age 65 years, and for men 80 years and older with no prior fracture".[4]
Screening tool
- There are two major methods, that is suggested to use for screening osteoporosis; they include:
- Dual energy x-ray absorptiometry (DXA) of both hip and lumbar spine bones
- Quantitative ultrasonography of the calcaneus
- Although quantitative ultrasonography has lower price, more portability, lower ionizing radiation exposure for patients, and otherwise the same power of fracture prediction (in femoral neck, hip, and spine) comparing with DXA method, current diagnostic and treatment criteria rely on DXA of the hip and lumbar spine.
Screening protocol
- After an initial screening bone mineral density (BMD), optimal intervals to repeat the test may include the followings:
- 15 years for women with normal bone density or mild osteopenia: T-score of greater than −1.50
- 5 years for women with moderate osteopenia: T-score of −1.50 to −1.99
- 1 year for women with advanced osteopenia: T-score of −2.00 to −2.49 [5]
