Spinal cord injury (SCI) results in increased accumulation of
visceral adipose tissue (VAT). Anthropometrics may provide an alternative to
estimate VAT cross-section area (CSA) compared to magnetic resonance imaging (MRI). OBJECTIVE: To validate the use of anthropometrics, including abdominal
circumference and skinfold thickness (SFT) measurements against MRI to predict
subcutaneous adipose tissue (SAT) and VAT cross-sectional areas in persons with
SCI. DESIGN: Cross-sectional. SETTING: Clinical research center PARTICIPANT:
Twenty-two men with motor complete SCI METHODS: Anthropometric measurements and
MRI were taken during a single visit. Abdominal circumference and SFT were used
to derive prediction equations for subcutaneous adipose tissue (SATAnthro-CSA)
and VAT (VATAnthro-CSA). Three-axial MRI at the level of umbilicus was used to
establish the prediction equations. VATAnthro-CSA was compared against body mass
index (BMI), waist circumference, and SFT. Bland-Altman plots were used to
determine limits of agreement between prediction equations and MRI. MAIN OUTCOME
MEASUREMENTS: SAT and VAT cross-sectional areas. RESULTS: SATAnthro-CSA explained
76% of the variance in SAT cross-sectional area (r(2) = 0.76, standard error of
the estimate [SEE] = 49.5 cm(2), P <.001). VATAnthro-CSA explained 72% of VAT
cross-sectional area (r(2) = 0.72, SEE = 45.8 cm(2), P <.001). Compared to
VATAnthro-CSA, BMI, waist circumference, and SFT explained only 37%, 63%, and
31%, respectively, in the variance of VAT MRI. CONCLUSION: Abdominal
circumference and SFT demonstrated an alternative way to predict VAT CSA.
VATAnthro-CSA estimated VATMRI more accurately than BMI, waist circumference, and
SFT in individuals with chronic SCI. LEVEL OF EVIDENCE: I.
