dc.description.resumoBackground: The prevalence of abnormal nutritional status has increased in children and adolescents.Nutritional assessment is important for monitoring the health and nutritional status. Bioelectrical impedancevector analysis (BIVA) combines changes in tissue hydration and structure and body composition that can beassessed.Objectives: The objective of this study was to use BIVA to evaluate nutritional status in 60 prepubertalchildren, aged between 8 and 9 years, supplemented with zinc, to detect possible changes in body composition.Design: We performed a randomized, controlled, triple-blind study. The children were divided into the controlgroup (CG; sorbitol 10%,n 29) or the experimental group (EG; 10 mg Zn/day,n 31), and the duration ofthe experiment was 3 months. Anthropometric assessments were performed for all of the children.Results: The body mass index-for-age increased after oral zinc supplementation in the EG (p 0.005). BIVAindicated that the CG demonstrated a tendency for dehydration and decreased soft tissue and the EGdemonstrated a tendency for increased soft tissue, primarily the fat-free mass. After analyses of BIVA ellipses,we observed that this method could detect improvements in body composition in healthy children supple-mented with zinc.Conclusions: These results suggest that BIVA could be an auxiliary method for studying a small populationundergoing zinc intervention.pt_BR
