Assessment of clinical measures of total and regional body composition from a commercial 3-dimensional optical body scanner

Three‐dimensional optical body shape and features improve prediction of metabolic disease risk in a diverse sample of adults

“…It should be noted that, whereas 3DO systems are increasingly being used in clinical and field settings, their adoption in clinical practice is not universal, and access to 3DO technology may be limited in certain settings [23]. Although the WC + anthropometric model increased the AUC compared with model 1, the proper identification of 16 individuals of the 3DO model 4 compared to a WC assessment further highlights the importance of other body shape variables as significant predictors of MetS disease risk.…”

“…Seventeen body composition estimates are also derived from these measures using proprietary algorithms built into the system software. Bennett et al [23] described the accuracy (Lin's concordance correlation coefficient, CCC) and precision (coefficient of variation, CV) of fat and fat‐free mass (CCC > 0.95; CV < 1.94%), whole‐body volume (CCC = 0.99; CV = 1.45%), and circumference measurements (CCC > 0.97; CV < 0.63%) in a sample of adults (age 18‐89 years) stratified by BMI and ethnicity [23]. With the 3DO shown to be accurate compared with criterion measures for body composition and anthropometry, we aimed to use the 3DO variables exclusively as a simplified assessment technique to improve the prediction of MetS.…”

“…Given the relative affordability and convenience of 3DO scanning for body composition assessment, rapid expansion of this technology has occurred in clinical practice [23]. With its ease of use and ability to track body composition trajectories with repeated measurements, these tools have the potential to inform patient education regarding disease risk and aid medical professionals in mitigating risk.…”

“…These markers of fat and tissue distribution, with further emphasis on central obesity, can now be captured noninvasively, with much greater frequency, using three-dimensional optical (3DO) imaging scanners in individuals of all ages, provided that they are capable of standing in the required pose for the duration of the test [21,22]. 3DO scanners are also capable of quickly capturing these anthropometrics along with additional body shape (volumes and circumferences) and composition (fat-free mass, fat mass, visceral fat mass) metrics that are also linked to MetS risk [10,20,23]. Ng et al [24] showed the ability for 3DO body shape by principal components analysis to predict serum lipid and diabetes markers, whereas a recent meta-analysis highlighted the impact of markers of central fatness, such as WC being associated with higher all-cause mortality risk [25].…”

Digital Anthropometry for Body Circumference Measurements: European Phenotypic Variations throughout the Decades

“…Because tape-based body measurements may not be culturally or socially acceptable and also exhibit poor reliability, especially in overweight and obese subjects [ 46 , 47 , 48 ], there was the need for the development and validation of accessible, valid, reproducible, and cost-effective technologies that are capable of providing robust measurements of lengths and circumferences and body composition estimates [ 49 ]. Digital anthropometry by three-dimensional optical imaging systems has recently been shown to provide non-invasive, accurate, and precise measurements of body circumference [ 49 , 50 ].…”
