Anthropometric evaluation through images: findings from the SCANNER software package.

Abstract

ObjectiveTo compare the waist-to-height ratio (WHtR) agreement between synthetic data and the Smart Computerised Anthropometric NavigatioN and Evaluation Resource (SCANNER) software package. MethodsOne hundred and ten 3D digital humans (55 for each sex) were created to obtain synthetic values. WHtR was obtained through the waist circumference and height division, both in centimetres. These data were programmed and obtained directly from the synthetic models. SCANNER v0.01 was coded by the researchers using Matlab. Differences between the objective WHtR and the one the SCANNER software package estimated were quantified using standard errors, Spearman's correlation and the Bland-Altman plot. ResultsUsing the Spearman correlation, an agreement level of 0.982 was identified. Using the Bland-Altman plot, the agreement level was high, with a Rho value of 0.983 (95% CI: 0.977 to 0.988). Finally, when the standard errors were quantified, there was an overall error (between the synthetic data created and the computed one) of 0.49%, being higher in men (0.81%) than in women (0.18%). ConclusionsThe SCANNER software package is a straightforward tool that would facilitate the estimation of WHtR in distance participants or patients.
