“…These equations have disadvantages compared to BIVA, as they assume a constant individual hydration status, meaning the same equation evaluates all individuals in the same way without distinguishing any differences that occur during the growth and development process among children and adolescents. This can result in standard estimation errors when applied to populations with characteristics different from those of the groups in which the equation was developed (Gomes et al 2021).…”

Background: Bioelectrical Impedance Vector Analysis (BIVA) emerges as a technique that utilizes raw parameters of bioelectrical impedance analysis and assumes the use of a reference population for information analysis. Objective: To summarize studies that have utilized BIVA in children and adolescents without diagnosed diseases. Methods: A systematic search was conducted in nine electronic databases (CINAHL, LILACS, PubMed, SciELO, Scopus, SPORTDiscus, Science Direct, MEDLINE, and Web of Science). Studies with different designs which allowed extracting information regarding reference values of BIVA in children and adolescents without diagnosed diseases, aged 19 years or younger, were included. The systematic review followed PRISMA procedures and was registered in PROSPERO (registration: CRD42023391069). Results: After applying the eligibility criteria, 36 studies were included. Twenty studies (55.6%) analyzed body composition using BIVA, thirteen studies (36.1%) aimed to establish reference values for BIVA, and three studies (8.3%) investigated the association of physical performance with BIVA. There was heterogeneity regarding the reference populations employed by the studies. Fifteen studies used their own sample as a reference (41.6%), four studies used the adult population as a reference (11.1%), and five studies used reference values from athletes (13.9%). Conclusion: Despite the wide applicability of BIVA, studies were found to utilize reference values with characteristics that diverged from the populations of interest.
