2. Bioelectrical impedance analysis - Wikipedia

   en.wikipedia.org/wiki/Bioelectrical_impedance...

   The equation (the squared value of height divided by impedance measurements of the right half of the body) showed a correlation coefficient of 0.92 with total body water. This equation, Hoffer proved, is known as the impedance index used in BIA. [16] In 1983, Nyober validated the use of whole body electrical impedance to assess body composition ...

3. Body composition - Wikipedia

   en.wikipedia.org/wiki/Body_composition

   A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA). [1]

4. Dual-energy X-ray absorptiometry - Wikipedia

   The radiation dose of current DEXA systems is small, [24] as low as 0.001 mSv, much less than a standard chest or dental x-ray. [25] [26] However, the dose delivered by older DEXA radiation sources (that used radioisotopes rather than x-ray generators) could be as high as 35 mGy, [27] [28] [29] considered a significant dose by radiological ...

6. Is BMI or Body Fat More Important? - AOL

   An X-ray of your entire body can help a healthcare provider work out your body composition, or how much of your body is made up of fat, muscle and bone. Bioelectrical impedance analysis (BIA).

7. Body fat percentage - Wikipedia

   en.wikipedia.org/wiki/Body_fat_percentage

   The body fat percentage is a measure of fitness level, since it is the only body measurement which directly calculates a person's relative body composition without regard to height or weight. The widely used body mass index (BMI) provides a measure that allows the comparison of the adiposity of individuals of different heights and weights ...

8. Why BMI is not the obesity measurement we need - AOL

   www.aol.com/why-bmi-not-obesity-measurement...

   A big part of the problem is relying too much on body mass index (BMI), which is often used to define obesity as a BMI over 30 kilograms per square meter (kg/m²) for people of European descent ...

9. Dual X-ray absorptiometry and laser - Wikipedia

   en.wikipedia.org/wiki/Dual_X-ray_absorptiometry...

   The body consists of three main components: bone mineral, lean soft tissue (skin, blood, water and skeletal muscle) and adipose tissue (fat and yellow bone marrow). These different components have different x-ray attenuating properties.
