Hydrodensitometry | definition of hydrodensitometry by Medical dictionary
un·der·wat·er weigh·ing (ŭn'dĕr-waw'tĕr wā'ing)
Assessment of body volume by measuring a person's weight in air and again under water; loss of scale weight (corrected for water density) equals body volume. Body density (body mass:volume ratio) is then used to compute percent body fat.
, hydrostatic weighing
The weighing of an object immersed in water and subsequent measurement of the water displaced. The specific gravity of the body can be estimated from that information, and the percentage of the body fat can be estimated. See: lean body mass

Fat mass (FM) was highly correlated with that determined by hydrodensitometry
, with subcutaneous fat measured as a sum of 10 skinfolds and also with visceral fat determined as an area on the computed tomography (CT) scan.
This slope was influenced by an outlier (the subject with the greatest body fat), nevertheless the relationship is consistent with a previous study reporting a similar relationship when NIR was compared with hydrodensitometry
(25,26) and suggests t his technique would be inappropriate for use in a longitudinal study.
