Comparison of human body surface area calculation formulas with three-dimensional anthropometry / 解剖学报

ABSTRACT

Objective To observe the difference of the human body surface area (BSA) formula based on three-dimensional measurement in practical application. Methods The data of 1249 college students (639 males, 610 females) from physical health examination in 2018 were selected. Using the one-way factorial analysis of variance (ANOVA), correlation analysis and Bland-Altman comparative analysis, comparisons between the BSA values using four BSA calculation formulas based on three-dimensional measurement and with the traditional formula measurement by Yongmei Hu's were made as well. Results There were significant statistical differenes between the BSA values of the formulas (P 0. 985) were also rather high. Results from Hu Yong-mei's formula were higher than the other four 3D formulas in both genders, with the BSA of males 7. 32%-12. 11% higher than the mean while female BSA values were 5. 53%-11.72% above the average. It has been shown from the Bland-Altman analysis that the formula from ChiYuang Yu had the highest consistency score (95 % CI 1.021-1.034) among the selected four 3D measurement formulas. Conclusion Within the four BSA formulas based on 3D measurement principle, ChiYuang Yu's formula is relatively more suitable to estimate the BSA values of both Chinese males and females.
