A T score of -1 to +1 is considered normal bone density. A T score of -1 to -2.5 indicates osteopenia (low bone density). A T score of -2.5 or lower is bone density low enough to be categorized as osteoporosis.
A Z-score compares your bone density to the average values for a person of your same age and gender. A low Z-score (below -2.0) is a warning sign that you have less bone mass (and/or may be losing bone more rapidly) than expected for someone your age.
A T-score of 1 to 2.5 SD below the young adult mean (-1 to -2.5 SD) indicates low bone mass. A T-score of 2.5 SD or more below the young adult mean (more than -2.5 SD) indicates the presence of osteoporosis.
Normal bone mass should be 3-5 percent, while body water percentage should on average be between 45 and 65 percent and muscle mass, about 75- 89 percent for men under 40 and 63-75.5 percent for women under 40.
For postmenopausal women and men age 50 years and older, the T-score is the number that is used for diagnostic classification, as follows: A T-score of -1.0 or above is normal bone density.
Bone Mass. Bone content is the percentage of bone mineral as compared to total body weight. The average bone content for adults is 3-5%. This measurement is good to keep track over a long period of time as bone mass can decline slowly with age.
A T score of -1 to +1 is considered normal bone density. A T score of -1 to -2.5 indicates osteopenia (low bone density). A T score of -2.5 or lower is bone density low enough to be categorized as osteoporosis.
Weight-bearing exercises, such as walking, jogging, and climbing stairs, can help you build strong bones and slow bone loss.
As a general rule, z-scores lower than -1.96 or higher than 1.96 are considered unusual and interesting. That is, they are statistically significant outliers.
T-Scores between -1 and -2.5 show that an individual has low bone mass, while a T-Score of -2.5 or below means a person has osteoporosis. The lower a person's T-Score, the more serious their bone loss. This score also indicates their risk of suffering a bone break or fracture.
Can I improve my T-score? In some cases, a T-score can be improved. However, it depends on where your score falls within the risk range and your lifestyle. Building up your bone density may involve taking medications as prescribed, eating plenty of foods that contain calcium and vitamin D, and exercising regularly.
Here are the ranges: A normal T-score falls between +1 and -1. Scores between -1 and -2.5 indicate low bone density, also called osteopenia. A T-score of -2.5 or lower indicates an established case of osteoporosis.
Bone loss begins to occur at an approximate rate of 0.25% a year and is variable depending on many genetic and environmental factors. This may be considered the second stage towards osteopenia and/or osteoporosis. It is important to understand that this is a perfectly normal part of the aging process.
DXA Scan Results
T-score of -1.0 or above = normal bone density. T-score between -1.0 and -2.5 = low bone density, or osteopenia. T-score of -2.5 or lower = osteoporosis.
Your bone density is considered normal. Between -1 and -2.5. Your score is a sign of osteopenia, a condition in which bone density is below normal and may lead to osteoporosis. -2.5 and below. Your bone density indicates you likely have osteoporosis.
Bone Mass is the computation or estimated weight of bone mineral in the body. Studies suggest that a healthy bone mass for women weighing less than 50 kg is 1.95 kg. For women weighing between 50 to 75 kg, the healthy bone mass is 2.40 kg and for those weighing more than 75 kg, the healthy bone mass is 2.90 kg.
The T-score measures your current bone density. A score of -1 and above means your bone density is normal. Anything between -1 and -2.5 indicates osteopenia. A score of -2.5 or below means that it is very likely that you have osteoporosis.
Many people can live well with osteoporosis and avoid breaking bones in the first place. But if you have had fractures, it's important to learn about the steps you can take to maintain a good quality of life.
The mean residual life expectancy of a 50-year-old man beginning osteoporosis treatment can be estimated at 18.2 years and the residual life expectancy of a 75-year-old man beginning treatment estimat- ed at 7.5 years. The corresponding estimates in women are 26.4 years and 13.5 years.
The skeleton of most females weighs between 1.5kg and 2.5kg. Your bone marrow can weigh up to 2-3kg on top of the weight of your bones.
Weight-bearing aerobic activities
Examples include walking, dancing, low-impact aerobics, elliptical training machines, stair climbing and gardening. These types of exercise work directly on the bones in your legs, hips and lower spine to slow mineral loss.
