- What is bone mass?
(Applicable age 18 - 99)
This feature indicates the amount of bone (bone mineral level, calcium or other minerals) in the body.
Research has shown that exercise and the development of muscle tissue are related to stronger, healthier
bones. While bone structure is unlikely to make noticeable changes in a short period, it is important that
you develop and maintain healthy bones by having a balanced diet and plenty of exercise. People worried
about bone disease should consult their physician. People who suffer from osteoporosis or low bone
densities due to advanced age, young age, pregnancy,hormonal treatment or other causes, may not get
accurate estimations of their bone mass.

amounts of bone masses, by weight. (Source: Tanita Body Weight Science Institute)

“Estimated bone mass” is a value estimated statistically based on its correlation with the fat-free amount
(tissues other than the fat). “Estimated bone mass” does not give a direct judgment on the hardness
or strength of the bones or the risks of bone fractures. If you have concerns over your bones, you are
recommended to consult a specialist physician.
