High-standard predictive equations for estimating body composition using bioelectrical impedance analysis: a systematic review

“…A total of 14,912 males, 17,362 females, and 534 subjects without any sex designated were included in 14 studies [34,42,47,50,52,54,61,66,71,[77][78][79][80][81][82] aimed to develop predictive equations for adults (from 18 to 65 years old) from the general population. A total of 885 males and 396 females were included in 11 studies [31,39,48,51,62,69,[83][84][85][86][87][88] aimed to develop predictive equations for athletes. A total of 1469 males and N = 2111 females were included in 17 studies [36,38,46,53,60,63,67,68,[89][90][91][92][93][94][95][96][97] aimed to develop predictive equations for elderly people.…”

Bioelectrical Impedance Vector Analysis, Nutritional Ultrasound®, and Handgrip Strength as Innovative Methods for Monitoring Critical Anorexia Nervosa Physical Recovery: A Pilot Study

“…These limitations have sparked interest in alternative methods such as BIVA. BIVA offers advantages such as affordability, portability, speed, and the absence of radiation exposure, analyzing impedance vectors and phase angle data to assess body water distribution, body cell mass, and cellular integrity, serving as indicators of nutritional status [11]. Similarly, NU ® employs ultrasound technology to target fat-free mass and fat mass, presenting an emerging, cost-effective, portable, and non-invasive solution.…”

Validation of Bioelectrical Impedance Devices for the Determination of Body Fat Percentage in Firefighters

“…These values are configured into customized algorithms to estimate body water and quantify tissue components, based upon body mass, to estimate body fat percent (14). The evolution of single-and multi-frequency analysis techniques, in conjunction with the accompanying algorithms, has substantially improved the accuracy and precision of this method of body composition assessment over time (21). This has subsequently led to advancements in multifrequency devices and predictive algorithms that may be available for commercial use or within athletic settings (14,21).…”
