%X comparison of body fat using anthropometry, bioelectrical impedance and dexa in elderly women. verify correspondence and compare percentage body fat (%bf) estimates by skinfold thickness (skt), bioelectrical impedance analysis (bia) and dexa. twenty voluntaries women (aged 62 - 79 yr) were assessed. the body fat was estimated using two different equations of skt(jackson (19); durning and womersley, (20)), bia using two-predictions formulas (23) and dexa. to compare mean values of %bf was used analysis of variance for repeated measures (anova _ bonferroni), the correlation of the inter-method was verified by pearson correlation coefficients (r), and correspondence between prediction formulas was tested by using the approach by bland and altman (25). the %bf assessed by bia (23) shown poor correlation (r<0.5) with two skt equations. the %bf ranged from 31.5 ¡À 5.5 to 41.2 ¡À 6.1 (mean ¡À sd) for jackson (19) e dexa, respectively. the analysis of variance shown no significant differences (p >0,05) between methods and/or equations by bia (rjl-compcorp) vs. dc-jackson (19). there were observed significant differences (p < 0,001) between all comparisons. the correspondence between rjl-compcorp vs. deurenberg (23) was good and the same was observed for dexa vs. durning and womersley (20). although the methods and/or equations used in this study have been commonly utilized to estimate bf in elderly subjects, they neither must be used as a standard method. each method has limitations and the comparison can be useful for interpretation of results
