Most people reach their peak bone mass around age After that, bone remodeling continues, but you lose slightly more bone mass than you gain. How likely you.

Bones naturally become thinner as you grow older. This is because existing bone tissue is broken down faster than new bone. Your results · above -1 SD is normal · between -1 and SD is defined as mildly reduced bone mineral density (BMD) compared with peak bone mass (PBM) · at or. A T-score of SD or more below the young adult mean (at or more than SD) indicates the presence of osteoporosis. In general, the risk for bone fracture.
The T-score is the number of standard deviations below the average for a young adult at peak bone density. There are different T-scores depending on which group. A T-score of to signifies osteopenia, meaning below-normal bone density without full-blown osteoporosis. This stage of bone loss is the precursor to. A Z-score compares a person's bone density with the average bone density of those of the same age, sex, and body size. A low score can indicate secondary. How often you should have your BMD measured depends on your age, the results of your previous DEXA scan, and your individual risk of fracture. Prevention Expand. Median (g/cm2), , Age maximum bone mass value (years), 34, Femoral neck. Maximum detected value (g/cm2), , Average (g/cm2), If your Z-score is above , your bone density is considered within the ranges expected for your age or normal according to the International Society for. Menopause ; Bone density ; On average, women lose up to 10% of their bone mass in the first five years after menopause.

Many people with osteoporosis do not know they have it until they break a bone. Screening is important to find these people before this happens, so they can. Who Should Get A Bone Mineral Density Test? · Fragility fracture after age 40 · Vertebral fracture or low bone mass identified on x-ray · Parental hip fracture. An x-ray technique called DXA or DEXA defines how far bone mineral density falls above or below the norm. In this case the norm is an average healthy woman in. In normal conditions, BMD increases during childhood and peaks at roughly age 25, which is maintained for about 10 years. After age 35, both men and women.
