Formulae for calculating body surface area in modern U.S. Army Soldiers

Body surface area equations for physically active men and women

“…Additionally, the SS20 scanning procedures involve a relatively closer placement of the arms toward the body in the measurement pose than used in the ANSUR II, potentially concealing some of the surface area of the axillary region in larger individuals. However, the overall error is small enough for many clinical uses (2.61% ± 1.73%), comparable to previous cross‐validation results (Looney et al, 2020), and the surface area of this region is less likely to be exposed to occupational burns (Kauvar et al, 2006; Mirmohammadi et al, 2013), frostbite (Knapik et al, 2020), or direct heat transfer with the environment (de Dear et al, 1997). While the ANSUR II dataset has relatively fewer female participants than the current study (30.6% vs. 36.6%), we compared estimates from Model 7, which consists of separate best fit equations for females and males.…”

“…Lee et al (2008) used a ±2% bias cutoff as their threshold for BSA accuracy in their examination of commonly used equations from the literature. The cross-validation of existing formulae on the ANSUR II dataset resulted in an average RMSD of 0.055 ± 0.023 m 2 (Looney et al, 2020) or approximately 2.9%. Another consideration is diurnal variation, given that body mass normally fluctuates within ±2% throughout the day (Kenefick, 2018).…”

“…A series of formulae were derived from the data collected by the SS20 to estimate BSA in female and male US Marines from different combinations of sex (Female 0; Male 1), height (H, cm), and mass (M, kg) (Table 1). We compared the level of agreement with SS20‐measured BSA between estimates from the newly‐derived Marine Corps formulae and the ANSUR II formulae (Looney et al, 2020). The sex, height, and mass equations were used in each set (Model 7).…”

Zur Bedeutung der relativen Körperoberfläche und der Körperzusammensetzung für die Wärmebilanz des Menschen

“…Eine aktuelle Studie validiert vergleichend verschiedene Näherungsformeln anhand eigener 3D-Bodyscans an 93 Probanden [10]. Parameter der Näherungsformeln sind dabei in der Regel die Körpermasse m (kg), die Körpergröße H (m) oder der Body-Mass-Index BMI (kg/m 2 ).…”

“…Nur drei Publikationen geben für männliche und weibliche Subjekte unterschiedliche Berechnungsformeln an, obwohl sich die Körperformen von Männern und Frauen signifikant unterscheiden [11][12][13]. Im Ergebnis zeigt sich, dass geschlechtsspezifische Berechnungsformeln für Frauen und Männer zu einer besseren Genauigkeit bei der Bestimmung der absoluten Körperoberfläche führen [10]. Solche Formeln nutzt die medizinische Forschung und Praxis, wenn es z.…”
