  2. Dual-energy X-ray absorptiometry - Wikipedia

    en.wikipedia.org/wiki/Dual-energy_X-ray...

    Dual-energy X-ray absorptiometry (DXA, or DEXA [1]) is a means of measuring bone mineral density (BMD) with spectral imaging. Two X-ray beams, with different energy levels, are aimed at the patient's bones. When soft tissue absorption is subtracted, the bone mineral density (BMD) can be determined from the absorption of each beam by bone. Dual ...

  3. Bone density - Wikipedia

    en.wikipedia.org/wiki/Bone_density

    A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

  4. Trabecular bone score - Wikipedia

    en.wikipedia.org/wiki/Trabecular_bone_score

    The trabecular bone score is a textural parameter that can be applied to DEXA, which quantifies the local variations in gray level. TBS is derived from the evaluation of the experimental variogram, obtained from the grayscale DEXA. [citation needed] It was found that TBS is a reflection of the structural condition of the bone microarchitecture.

  5. Human body weight - Wikipedia

    en.wikipedia.org/wiki/Human_body_weight

    Human body weight is a person's mass or weight.. Strictly speaking, body weight is the measurement of mass without items located on the person. Practically though, body weight may be measured with clothes on, but without shoes or heavy accessories such as mobile phones and wallets, and using manual or digital weighing scales.

  6. Physical Activity Guidelines for Americans - Wikipedia

    en.wikipedia.org/wiki/Physical_Activity...

    In 2018, HHS released an update to the first set of guidelines. This 2018 edition provides guidelines for people aged three years and older and summarizes the new knowledge gained from studies that were conducted since the first edition was released in 2008. These Guidelines can be tailored to meet individual interests, lifestyles, and goals.

  7. Waist–hip ratio - Wikipedia

    en.wikipedia.org/wiki/Waist–hip_ratio

    In an American sample of 459 healthy men and women participating in the ongoing 'Baltimore Longitudinal Study of Aging', the mean annual increase [with age] in waist circumference was more than 3 times as great for the participants in the white-bread cluster compared with the participants using a diet that is high in fruit, vegetables, reduced ...

  8. Prostate cancer screening - Wikipedia

    en.wikipedia.org/wiki/Prostate_cancer_screening

    The Canadian Task Force on Preventive Health Care in 2014 strongly recommended against screening in those under 55 and over 70 years of age. [11] They weakly recommended against screening among those 55–69. [11] Some men have germ-line mutations associated with prostate cancer development (e.g., BRCA1, BRCA2, HOXB13). Screening and its ...

  9. Waist-to-height ratio - Wikipedia

    en.wikipedia.org/wiki/Waist-to-height_ratio

    The waist-to-height ratio (WHtR, [a] or WSR: waist-to-stature ratio) is the waist circumference divided by body height, both measured in the same units.. WHtR is a measure of the distribution of body fat.
