 AB    OBJECTIVE: To compare assessments of nutritional status in HIV+ persons
       by bioelectrical impedance analysis (BIA) to assessments by methods
       employing weight-for-height measures (PIBW and BMI). METHODS: In 121
       HIV+ outpatients we measured: percent of ideal body weight (PIBW) from a
       table (Build Study 1979, Society of Actuaries), body mass index (BMI =
       weight [in kilograms] divided by height [ht] in meters [m] squared), and
       body cell mass (BCM by BIA-RJL-101-A, Fluid Status 2.0). Body cell mass
       (nBCM) was normalized by height (BCMht = BCM divided by height) and
       expressed as a percentage of mean BCMht for 3 seronegative control
       subjects matched for gender, race and age. BMI, PIBW, and nBCM,
       stratified by CD4 counts, were compared by ANOVA. RESULTS: The sample
       included 89% men, 11% women; 59% whites, 37% blacks and 4% other. CD4
       counts (cells/mm3) were available for 90.9% of subjects. TABULAR DATA,
       SEE ABSTRACT VOLUME. CONCLUSION: In comparison to subjects with higher
       CD4 cells in this sample, mean BMI and PIBW were reduced, but not
       significantly, when CD4 cells were below 50 cells/mm3. However,
       significant reductions in body cell mass (nBCM) were observed in this
       sample in subjects with low CD4 cells (< 200 cells/mm3). These findings
       suggest that BIA technology may be more useful for early detection of
       occult wasting in persons with HIV/AIDS in comparison to
       weight-for-height methods.
