dc.description.abstract | Background: Individuals with high body fat have a higher risk of mortality.
Numerous anthropometric-based predictive equations are available for body
composition assessments; furthermore, bioelectrical impedance analysis (BIA)
estimates are available. However, in older adults, the validity of body fat
estimates requires further investigation.
Objective: To assess the agreement between percentage body fat (BF%)
estimates by BIA and five predictive equations based on anthropometric
characteristics using dual X-ray absorptiometry (DXA) as reference method.
A secondary objective was to identify whether excluding short-stature women
improves the agreement of BF% estimates in a group of community-dwelling,
older Mexican women.
Methods: A concordance analysis of BF% was performed. A total of
121 older women participated in the study. Anthropometric information,
BIA, and DXA body composition estimates were obtained. Five equations
using anthropometric data were evaluated in order to determine body fat
percentage (BF%) using DXA as reference method. Paired t-test comparisons
and standard error of estimates (SEE) were obtained. The Bland-Altman plot
with 95% limits of agreement and the concordance correlation coefficient
(CCC) were used to evaluate the BF% prediction equations and BIA estimates.
Results: The mean age of the study participants was 73.7 ( 5.8) years
old. BIA and the anthropometric based equations examined showed mean
significant differences when tested in the entire sample. For the taller women
(height > 145 cm), no significant difference in the paired comparison was
found between DXA and BIA of BF% estimates. The mean BF% was 40.3 ( 4.8)
and 40.7 ( 6.2) for DXA and BIA, respectively. The concordance between
methods was good (CCC 0.814), (SEE 2.62). Also, in the taller women subset,
the Woolcott equation using waist-to-height ratio presented no significant
difference in the paired comparison; however, the error of the estimates was
high (SEE 3.37) and the concordance was moderate (CCC 0.693).
Conclusion: This study found that BIA yielded good results in the estimation of
BF% among women with heights over 145 cm. Also, in this group, theWoolcott
predictive equation based on waist circumference and height ratio showed no
significant differences compared to DXA in the paired comparison; however,
the large error of estimates observed may limit its application. In older women,
short stature may impact the validity of the body fat percentage estimates of
anthropometric-based predictive equations. | es |
