| Resumo: | Background: Zinc is an essential nutrient that is required for numerous metabolic functions, and zincdeficiency results in growth retardation, cell-mediated immune dysfunction, and cognitive impairment.Objective: This study evaluated nutritional assessment methods for zinc supplementation in prepubertal non-zinc-deficient children.Design: We performed a randomised, controlled, triple-blind study. The children were divided into a controlgroup (10% sorbitol,n 31) and an experimental group (10 mg Zn/day,n 31) for 3 months. Anthropometricand dietary assessments as well as bioelectrical measurements were performed in all children.Results: Our study showed (1) an increased body mass index for age and an increased phase angle in theexperimental group; (2) a positive correlation between nutritional assessment parameters in both groups; (3)increased soft tissue, and mainly fat-free mass, in the body composition of the experimental group, asdetermined using bioelectrical impedance vector analysis; (4) increased consumption of all nutrients,including zinc, in the experimental group; and (5) an increased serum zinc concentration in both groups(pB0.0001).Conclusions: Given that a reference for body composition analysis does not exist for intervention studies,longitudinal studies are needed to investigate vector migration during zinc supplementation. These resultsreinforce the importance of employing multiple techniques to assess the nutritional status of populations. |
