Resumo
Objective: To compare two methods for
evaluating total body fat and its distribution.
Methods: Cross-sectional, cohort-nested
study. Sixty-two women received a
nutritional status evaluation which included
total body fat (BF) obtained through the sum
of skinfolds (ΣSF) and bioimpedance (BIA).
Visceral fat distribution was measured using
ultrasonography (USG) (intra-abdominal fat
thickness) (IAT) and waist circumference
( WC). The concordance correlation
coefficient (CCC) and the determination
coefficient (r 2 ) were calculated. Results:
Mean patient age was 48.19 (8.99) years.
Thirty-six women (58.06%) had a very
large WC and 42 (67.74%) had high body
fat. There was moderate concordance
(r 2 = 0.42; CCC = 0.59; p < 0.01) between the
methods for determining body fat (%) and
optimal concordance (r 2 = 0.90; CCC = 0.91;
p < 0.01) for body fat (kg) determined by BIA
and ΣSF. The comparison between WC and
IAT (USG) showed moderate concordance
(r 2 = 0.49; p < 0.01) between the methods.
Conclusions: Moderate concordance in
determining total body fat (%) and optimal
concordance in determining body fat
(kg) were found between the methods.
Moderate concordance was found between
the methods for determining body fat
distribution.
