The aim of this studywas to gather information on the use of stable isotopes to measure total bodywater and body composition scan in children. We selected studies in the last13 years, in addition to classical studies on the subject, indexed in the databasePubMed, LILACS, BVS and SciELO. The body composition was characterized by theamount of bone tissue, muscle and adipose tissue, also including the organs aswell as levels of body water. Your knowledge becomes increasingly important inlight of the changes that occur in the nutritional status of various types ofdiseases in frameworks, such as diabetes mellitus, protein energy malnutrition,in cases of obesity and metabolic syndrome. The ability to accurately assessbody fat mass especially in children is associated with the importance ofeffective strategies for prevention and treatment of childhood obesity.Historically, in addition to clinical applications, measurements of totalbody water were used to determine body composition in nutritional studies. Tothe knowledge of the body composition, the body water can be measured and usedby the ingestion of a dose of labeled water. The measured isotope enrichmentis a function of the amount of body water. The method of deuterium isparticularly interesting for the assessment of body composition in children,due to its characteristics of collection and analysis.
