The risk factors for low bone density and primary considerations for a bone density test include: females age 65 or older. [4] males age 70 or older. [4] people over age 50 with: previous bone fracture from minor trauma. [4] rheumatoid arthritis. [4] low body weight. [4] a parent with a hip fracture. [4] individuals with vertebral abnormalities ...
Bone density testing is recommended for older women whose risk of breaking a bone is the same or greater than that of a 65‑year‑old white woman with no risk factors other than age.
Older women aren't the only ones who need a bone density test. Younger women who have a fracture risk that’s similar to women who are 65 and up should also get tested.
A normal T score is -1.0 and above, low bone density is between -1.0 and -2.5, and osteoporosis is -2.5 and lower. A Z score is just a comparison of what a patient's bone mineral density is in comparison to the average bone mineral density of a male or female of their age and weight.
In particular, physical exercise can be beneficial for bone density in postmenopausal women, [140] and lead to a slightly reduced risk of a bone fracture (absolute difference 4%). [141] Weight bearing exercise has been found to cause an adaptive response in the skeleton, [142] promoting osteoblast activity and protecting bone density. [143]
Medicare will cover bone density scans for a person who meets certain medical requirements, such as osteoporosis risk factors.
Bone age is the degree of a person's skeletal development. In children, bone age serves as a measure of physiological maturity and aids in the diagnosis of growth ...
Information from the DXA scanner creates a bone mineral density T-score by comparing a patient's density to the bone density of a healthy young person. Bone density between 1 and 2.5 standard deviations below the reference, or a T-score between −1.0 and −2.5, indicates osteopenia (a T-score smaller than or equal to −2.5 indicates ...
