What is the WHO criteria for osteoporosis?
What is the WHO criteria for osteoporosis?
Osteoporosis has been operationally defined on the basis of bone mineral density (BMD) assessment. According to the WHO criteria, osteoporosis is defined as a BMD that lies 2.5 standard deviations or more below the average value for young healthy women (a T-score of <-2.5 SD) (1,6).
What is the diagnostic evaluation for the osteoporosis?
To diagnose osteoporosis and assess your risk of fracture and determine your need for treatment, your doctor will most likely order a bone density scan. This exam is used to measure bone mineral density (BMD). It is most commonly performed using dual-energy x-ray absorptiometry (DXA or DEXA) or bone densitometry.
What is the gold standard exam for diagnosing osteoporosis?
It may be done using X-rays, dual-energy X-ray absorptiometry (DEXA or DXA), or a special CT scan that uses computer software to determine bone density of the hip or spine. For various reasons, the DEXA scan is considered the “gold standard” or most accurate test.
What is BMD in bone density?
A bone mineral density (BMD) test measures how much calcium and other types of minerals are in an area of your bone. This test helps your health care provider detect osteoporosis and predict your risk for bone fractures.
Where is osteoporosis most common in the world?
Norway is one of the countries with the highest number of osteoporosis diagnoses per capita. Osteoporosis is a condition that leads to loss of bone mass and thereby a higher risk of incurring serious bone fractures.
What are risk factors for developing osteoporosis?
Risk factors
- Your sex. Women are much more likely to develop osteoporosis than are men.
- Age. The older you get, the greater your risk of osteoporosis.
- Race. You’re at greatest risk of osteoporosis if you’re white or of Asian descent.
- Family history.
- Body frame size.
Can a CT scan detect osteoporosis?
Osteoporosis is underdiagnosed. This study found that computed tomography (CT) scans can be used for detecting vertebral osteoporosis by comparing CT scans obtained for other reasons with dualenergy x-ray absorptiometry (DXA) scans performed within 6 months of the CT.
