title: Total body phosphorus in healthy women and ethnic variations.
abstract: Total body phosphorus (TBP) levels were measured in 90 black and 143 white healthy women to determine ethnic differences. The measurements were performed by in vivo delayed gamma neutron activation (DGNA) analysis at Brookhaven National Laboratory (BNL). Mean value of TBP in whites was 10.4% lower as compared with the black women (mean TBP in white women 401.4 +/- 57.5 g v. 447.7 +/- 57.7 g in black women). Both subgroups have a decrease in TBP with age with a rapid phase after the onset of menopause, which corresponds to bone loss. The decrease in TBP is similar in both ethnic groups with black women losing -1.59 g/yr (-0.33%/yr) and white women losing -2.08 g/yr (-0.45%/yr).
