“…In our study, we observed lower values of 3.0° and 2.4° for G1 and G2, respectively. These values were also lower than the average value reported in a study of seven children with osteogenesis imperfecta, who presented PA values of 4.8° (25). When the data were distributed by age group, lower PA values were observed in adolescents than in children, emphasizing a significant negative correlation between age and PA values.…”

Background Duchenne muscular dystrophy (DMD) is a disease characterized by progressive loss of functional muscle mass followed by changes in body composition. Objective This study aimed to describe and evaluate bioimpedance parameters in boys with DMD. Design This cross-sectional, descriptive study investigated children and adolescents diagnosed with DMD. Age, weight, height, resistance, and reactance data were collected. Phase angle and bioelectrical impedance vector analysis were calculated based on resistance and reactance values. Results We analyzed 43 boys aged between 2.7 and 19.8 years. Low-phase angle values were observed during the investigation of bioimpedance parameters. Bioelectrical impedance vector analysis showed that approximately 87% of the subjects presented vectors outside the tolerance ellipses, and only one patient presented vectors located within the 50% tolerance ellipse, indicating normally hydrated and a good body cell mass. Compared with the reference population, boys with DMD had lower levels of body cell mass. Conclusion Based on the evidence, compared with the reference population, patients with DMD had lower levels of body cell mass. This evidence points to bioimpedance parameters as useful tools for the nutritional evaluation and clinical management of patients with DMD.

“…PA has also been described as a sensitive and useful tool to detect changes in nutritional status in addition to being associated with the clinical prognosis of several diseases [4,5]. Pileggi et al [8] concluded that PA is a useful tool for detecting nutritional risk in children with osteogenesis imperfecta.…”

Bioelectrical Impedance Vector Analysis and Phase Angle on Different Oral Zinc Supplementation in Eutrophic Children: Randomized Triple-Blind Study

et al. 2019

The parameters derived from bioelectrical impedance, phase angle (PA) and bioelectrical impedance vector analysis (BIVA) have been associated with cell membrane integrity and body cell mass. Zinc is a micronutrient that exerts important structural functions and acts in maintaining cellular functionality. To evaluate cell integrity and body cell mass, PA and BIVA were evaluated in children orally supplemented with zinc at different concentrations. Anthropometric, bioelectrical (resistance and reactance) and serum zinc variables were collected from two randomized, triple-blind, controlled clinical trials. Sampling was composed of 71 children consisting of three groups: a control group who received a placebo and two experimental groups who received oral supplementation of 5 or 10 mg-Zn/day for three months. The three groups presented increases (p < 0.001) in the linear height and weight. In the group supplemented with 10 mg-Zn/day, there was an increase in reactance values (p = 0.036) and PA (p = 0.002), in addition to vector displacement (p < 0.001) in relation to the confidence ellipses. An increase in serum zinc concentration was found (p < 0.001) in all three groups. Whit this, the supplementation with 10 mg-Zn/day promotes changes in the integrity of the cell membrane associated with the increase in the cellular mass of healthy children.

“…Estudos vêm demostrando a ação do AF como indicador do estado nutricional nessa população, baixos valores de AF indicariam risco nutricional mesmo com IMC compatível com eutrofia. Alterações em nível celular ocorrem à frente das alterações teciduais, detectáveis pelos métodos antropométricos tradicionais, evidenciando a relevância do AF na prática clínica como instrumento de triagem e indicador de prognóstico 15,16 .…”

Introdução: O câncer infantil gera um grande impacto para a saúde pública. A avaliação da composição corporal pela impedância bioelétrica fornece os valores de ângulo de fase, diretamente relacionados a alterações funcionais na membrana celular e que têm sido usados para avaliar o estado nutricional e o prognóstico. Objetivo: Avaliar a correlação entre o ângulo de fase e os parâmetros do estado nutricional de pacientes oncológicos pediátricos em tratamento. Método: Estudo transversal realizado em um hospital público universitário. O estado nutricional foi verificado por meio das medidas de peso, altura, circunferência do braço, dobra cutânea tricipital, índice de massa corporal e circunferência muscular do braço. O ângulo de fase foi determinado pela impedância bioelétrica. Resultados: Foram incluídos 13 pacientes com média de idade de 103,2±39,7 meses, sendo 61,5% do sexo masculino, com prevalência da leucemia entre os diagnósticos. Constatou-se que a maioria (53,8%) dos pacientes estava em eutrofia. Houve forte correlação do ângulo de fase com os parâmetros de massa magra (r=0,923; p=0,000), massa corporal celular (r=0,911; p=0,000), massa extracelular (r=0,897; p=0,000) e peso corporal (r=0,920; p=0,000). Conclusão: Observaram-se correlações expressivas entre o ângulo de fase e os indicadores antropométricos, reforçando a hipótese de que o ângulo de fase pode antecipar a identificação de alterações na composição corporal, possibilitando uma intervenção nutricional precoce e melhor prognóstico.
