“…BMI may be valid as a nutrition marker as shown by Bechard et al; however, it may mask situations of muscle depletion since it does not discriminate among body compartments. It is very common among individuals classified as eutrophic or even obese according to BMI to present with lean mass depletion.…”

“…There are several techniques to assess body composition, such as mid–upper arm circumference (MUAC) and triceps skinfold thickness (TST), that describe fat and lean stores, besides bioelectrical impedance analysis (BIA). BIA is based on the passage of a low‐intensity electric current through the body, measuring primary components and estimating fat mass (FM), fat‐free mass (FFM), and total body water . Among the BIA parameters, the phase angle (PA), which indirectly represents FFM, is the most clinically established as it has shown a strong ability to predict outcomes in a wide variety of clinical situations …”

“…BIA is based on the passage of a low-intensity electric current through the body, measuring primary components and estimating fat mass (FM), fat-free mass (FFM), and total body water. 9 Among the BIA parameters, the phase angle (PA), which indirectly represents FFM, is the most clinically established as it has shown a strong ability to predict outcomes in a wide variety of clinical situations. [12][13][14] Considering the importance of body composition analysis as an adjunctive nutrition assessment and as a possible morbidity and mortality predictor in many clinical situations, it is necessary to conduct studies that demonstrate this ability, especially in critically ill children, because data are still scarce.…”

Background Nutrition markers may be useful for diagnosis and monitoring and, also, as additional indicators of estimating death risk. We tested the association of body composition indicators (mid–upper arm circumference and phase angle) with pediatric intensive care unit (PICU) length of stay and mortality in critically ill pediatric patients. Methods Data from children aged 2 months–18 years were collected, and bioelectrical impedance was performed to obtain phase angle. Severity was evaluated by scoring the Pediatric Index of Mortality. Descriptive statistics were reported for nominal variables. Receiver operating characteristic curve was used to analyze the association of phase angle with 30‐day mortality and to find the best cutoff. Survival probabilities and PICU length of stay were estimated using the Kaplan‐Meier method. Results We evaluated 247 children with a median age of 4.8 years whose main cause of admission was sepsis. Survival curves showed higher survival in patients with phase angle >2.8° compared with patients with phase angle ≤2.8° (P < .0001). Kaplan‐Meier time‐to‐event analysis showed that children with lower phase angle values were more likely to remain in the PICU (hazard ratio, 1.84; P = .003). Lower survival was also observed in patients who presented mid–upper arm circumference values ≤5th percentile (P < .03). Conclusions Mid–upper arm circumference and phase angle were associated with mortality and morbidity in critically ill children, suggesting that these parameters may be useful not only for nutrition diagnosis and monitoring, but also as an additional indicator in estimating prognosis.

“…Estudios recientes demuestran que, además de la aplicación tradicional de la CB en la estimación de la desnutrición, su empleo resulta de gran utilidad para la evaluación clínica y la vigilancia epidemiológica de la obesidad en países en desarrollo. 9,10,14 La combinación de la CB con el pliegue subcutáneo tricipital (PT) permite calcular, indirectamente, las áreas grasa (AG) y magra del brazo. 7 La estimación de estos parámetros de composición corporal posibilita no solo conocer las reservas calóricas y proteicas, sino también identificar los factores de riesgo relacionados con la malnutrición, tanto por déficit como por exceso.…”

“…Recent studies have demonstrated that, in addition to the traditional use of MUAC to estimate malnutrition, it is greatly useful for clinical assessment and epidemiological surveillance of obesity in developing countries. 9,10,14 The combination of MUAC and tricipital skinfold (TSF) allows to estimate, in an indirect manner, the upper arm fat area (UAFA) and the upper arm lean mass. 7 Estimating these body composition parameters enables to know calorie and protein reserves and also to identify risk factors related to malnutrition, both by excess and deficiency.…”

Introduction: Mid-upper arm circumference (MUAC) is widely recognized as an adequate indicator of nutritional status. Objective: To estimate the reference percentiles for MUAC, upper arm muscle area (UAMA), and upper arm fat area (UAFA) in the Argentine child and adolescent population using the LMS method (lambda, mu, sigma) Materials and methods: The sample was made up of schoolchildren aged 4.0-13.9 years living in Jujuy, Catamarca, Misiones, Buenos Aires, Mendoza, and Chubut. MUAC and tricipital skinfold anthropometric measurements were obtained between 2003 and 2008 as per standardized protocols. UAMA and UAFA were calculated, and percentiles by age and sex were estimated and compared using an analysis of variance. Results: A total of 22 736 schoolchildren (11 397 boys and 11 339 girls) were included. The 50 th percentile was higher for the MUAC and UAFA among girls and for the UAMA among boys. The MUAC curves showed sharper increases as of 7 years old in all percentiles among both boys and girls. A similar pattern was observed for the UAMA, with higher values among boys. Lastly, the UAFA showed a constant increase among girls and a stabilization among boys as of 11 years old. Differences for age were observed. Conclusions: The tabulated and plotted percentiles and the MUAC, UAMA, and UAFA may be used as local references for epidemiological and anthropological studies.
