ABSTRACT

El índice de masa corporal (IMC) es una eficaz herramienta para detectar la sobrecarga ponderal en niños y adolescentes, asociado a la adiposidad corporal. Objetivo. Analizar la concordancia, sensibilidad y especificidad de tres referencias internacionales de IMC/edad (OMS, IOTF y CDC) para diagnosticar el exceso ponderal y conocer su precisión diagnóstica para identificar el exceso de adiposidad con relación al área grasa braquial (AGB) en población infanto juvenil de Argentina. Materiales y métodos. Se realizó un estudio multicéntrico, descriptivo-comparativo y transversal entre 2003 y 2008, en 22.658 niños y adolescentes argentinos de 4 a 13 años de edad. A partir del peso, talla, circunferencia del brazo y pliegue tricipital, se calcularon IMC y AGB. Se analizó la concordancia, sensibilidad y especificidad de referencias de IMC/edad (OMS, CDC, IOTF) y la precisión diagnóstica (curvas ROC) para identificar exceso de adiposidad, a partir del AGB, así como el punto de corte óptimo (PCO). Resultados. Las tres referencias tuvieron buena concordancia. La mayor sensibilidad correspondió a OMS y la mayor especificidad a IOTF. El área bajo la curva (ABC) fue mayor en Z-IMC/IOTF en varones y en Z-IMC/OMS en mujeres. Los PCO mostraron discrepancias, siendo mayores con OMS. Conclusión. Las tres referencias muestran similar precisión diagnóstica para detectar alta reserva calórica, con puntos de corte óptimo para las puntuaciones Z-IMC menores a 2 Z scores. Esto resulta relevante para la identificación de exceso de adiposidad en poblaciones, en relación con la implementación de políticas públicas de prevención de enfermedades crónicas no transmisibles(AU)


The body mass index (BMI) is an effective tool to detect weight overload in children and adolescents, associated with body adiposity. Objective. To analyze the concordance, sensitivity and specificity of three international BMI/age references (WHO, IOTF and CDC) to diagnose excess weight and to know their diagnostic accuracy to identify excess adiposity in relation to the brachial fat area (BFA) in Argentine child-youth population. Materials and methods. A multicenter, descriptive- comparative and cross-sectional study was carried out between 2003 and 2008 in 22.658 Argentine children and adolescents between aged 4 to 13 years. From the weight, height, arm circumference and tricipital fold, BMI and BFA were calculated. The concordance, sensitivity, and specificity of BMI / age references (WHO, IOTF, CDC,) were analyzed and the diagnostic precision (ROC curves) to identify excess adiposity, from the BFA, as well as the optimal cut-off point (OCP). Results. The three references had good agreement, the highest sensitivity corresponded to WHO and the highest specificity to IOTF. The area under the curve (AUC) was greater in Z-BMI/IOTF in men and in Z-BMI/WHO in women. The OCPs showed discrepancies, being higher with WHO. Conclusion. The three references show similar diagnostic accuracy to detect high caloric reserve, but with cut-off points for Z-BMI scores less than 2 Z scores. This is relevant for the identification of excess adiposity in populations in relation to the implementation of public policies for the prevention of chronic non-communicable diseases(AU)

ABSTRACT

La obesidad se define por un exceso de masa grasa, sin embargo, hay otros indicadores antropométricos que pueden ser útiles para el diagnóstico de sobrepeso u obesidad; Objetivo. Determinar la exactitud diagnóstica del índice de masa corporal (IMC), circunferencia de la cintura (CC) e índice de forma corporal (ABSI) para el diagnóstico de sobrepeso u obesidad en una población adulta del Ecuador. Materiales y métodos. Se desarrolló un estudio observacional de corte transversal en el que participaron 253 sujetos con edades entre 20 y 60 años. Se midió peso, estatura, circunferencia de la cintura y porcentaje de grasa corporal (PGC). Se correlacionó el PGC con IMC, CC y ABSI y se estableció la sensibilidad y especificidad de estos indicadores para el diagnóstico de sobrepeso u obesidad con curvas ROC. Resultados. El PGC fue menor en hombres que en mujeres (30,9 vs 41,87), ABSI y CC fue mayor en hombres que en mujeres (0,079 vs 0,075) y (99,76 vs 91,25) respectivamente. Se encontró una correlación positiva fuerte (≥0,75) entre el PGC e IMC y CC. En la curva ROC, el área bajo la curva más alta se observa para el IMC (0,949), mientras que el área más baja se observa para ABSI (0,395). Conclusión. El IMC es el indicador con mayor precisión diagnóstica de sobrepeso u obesidad. ABSI no sería un indicador útil en el diagnóstico de sobrepeso u obesidad(AU)


Obesity is defined by an excess of fat mass, however, there are other anthropometric indicators that can be useful for the diagnosis of overweight or obesity; Objetive. To determine the diagnostic accuracy of the body mass index (BMI), waist circumference (WC) and body shape index (ABSI) for the diagnosis of overweight or obesity in an adult population of Ecuador. Materials and methods. An observational cross-sectional study was carried out in which 253 subjects aged between 20 and 60 years participated. Weight, height, waist circumference and percentage body fat (PBF) were measured. The PBF was correlated with BMI, WC and ABSI and the sensitivity and specificity of these indicators were established for the diagnosis of overweight or obesity with ROC curves. Results. The PBF was lower in men than in women (30.09 vs 41.87), ABSI and CC were higher in men than in women (0.079 vs 0.075) and (99.76 vs 91.25) respectively. A strong positive correlation (≥0.75) was found between % body fat and BMI and WC. On the ROC curve, the area under the highest curve is observed for BMI (0.949), while the lowest area is observed for ABSI (0.395). Conclusion. The BMI is the indicator with the highest diagnostic precision of overweight or obesity. ABSI would not be a useful indicator in the diagnosis of overweight or obesity(AU)

ABSTRACT

Body fat distribution seems to have different effects in cardiovascular diseases (CVD). We aimed to estimate the associations between lower limbs and trunk fat ratio and the 10-year CVD risk, and isolated risk factors in men and women. A total of 10,917 participants from ELSA-Brasil were eligible for this cross-sectional study. Associations between lower limb/trunk fat ratio with the percentage of 10-year CVD risk - according to the Framingham Risk Score - and its risk factors (systolic blood pressure, total cholesterol and HDL-cholesterol, diabetes, and use of antihypertensive medication) were performed using generalized linear models, linear and logistic regressions. All analyses were stratified by gender and adjustments were made by age, self-reported skin color, educational attainment, alcohol consumption, leisure physical activity, hypolipidemic drug use and, for women, menopausal status. In this study, 55.91% were women, with a mean age of 52.68 (SD = 6.57) years. A higher lower limb/trunk fat ratio was related to lower 10-year CVD risk, as well as a reduction in systolic blood pressure, total cholesterol, and antihypertensive drug use, also an increasing HDL-cholesterol in both genders, but this relationship was stronger in women. Besides, a protective relationship to diabetes was observed in women. Higher fat accumulation in the lower body, when compared to the trunk, seems to have a lower risk of CVD and associated risk factors - even in the presence of fat in the abdominal region - with women presenting lower risks than men.


A distribuição de gordura no corpo parece ter efeitos diferentes nas doenças cardiovasculares (DCV). Objetivou-se estimar as associações da razão de gordura entre membros inferiores e tronco com o risco de DCV em 10 anos e os fatores de risco independentes em homens e mulheres. Um total de 10.917 participantes do ELSA-Brasil eram elegíveis para este estudo transversal. As associações da razão de gordura entre os membros inferiores e tronco com o percentual de risco de DCV em 10 anos, de acordo com a Escala de Risco de Framingham, e os respectivos fatores de risco (pressão arterial sistólica, colesterol total e HDL colesterol, diabetes e uso de medicação anti-hipertensiva), foram avaliados com modelos lineares generalizados, lineares e de regressão logística. Todas as análises foram estratificadas por sexo, e os ajustes foram feitos por idade, raça/cor, escolaridade, consumo de álcool, atividade física, uso de medicação hipolipemiante e, para as mulheres, estado de menopausa. Na amostra do estudo atual, 55,91% eram mulheres, com média de idade de 52,68 anos (DP = 6,57). A maior diferença entre a gordura dos membros inferiores e tronco foi associada com menor risco de DCV em 10 anos e com redução na pressão arterial sistólica, colesterol total e uso de medicação anti-hipertensiva, assim como um aumento no HDL colesterol em ambos os sexos (mas essa correlação foi mais forte em mulheres). Além disso, foi observada uma relação protetora contra diabetes, apenas em mulheres. O acúmulo maior de gordura nos membros inferiores, comparado com o tronco, parece estar associado a um risco menor de DCV e aos fatores de risco, mesmo na presença de gordura na região abdominal, e esse efeito é mais forte nas mulheres que nos homens.


Las distribuciones de grasa corporal parecen tener diferentes efectos en las enfermedades cardiovasculares (ECV). Nuestro objetivo fue estimar las asociaciones entre extremidades inferiores/ratio de grasa troncal y el riesgo de ECV a los 10 años, y sus factores de riesgo aislados, en hombres y mujeres. Un total de 10.917 participantes de ELSA-Brasil fueron elegibles para este estudio transversal. Las asociaciones de la ratio de grasa entre la parte inferior del cuerpo y el tronco, con el porcentaje de riesgo de ECV a los 10 años, según la Escala de Riesgo de Framingham, y sus factores de riesgo (presión sanguínea sistólica, colesterol total y colesterol HDL, diabetes, y uso de medicación antihipertensiva), se realizaron usando modelos lineales generalizados, regresiones lineales y logísticas. Todos los análisis fueron estratificados por sexo y los ajustes se hicieron por edad, raza/color de piel autoinformado, nivel educativo, consumo de alcohol, actividad física durante el ocio, uso de medicamentos hipolipemiantes y, para mujeres, estatus menopáusico. En este estudio, un 55,91% fueron mujeres, con una media de edad de 52,68 (SD = 6,57) años. Una ratio de masa adiposa más alta entre las extremidades inferiores/tronco estuvo asociada a un riesgo menor de ECV en 10 años, también una reducción en la presión sistólica sanguínea, colesterol total, y el consumo de medicamentos antihipertensivos, también en un incremento del colesterol HDL en ambos sexos, pero esta relación fue más fuerte en mujeres. Asimismo, una relación protectora frente a la diabetes se observó solo en mujeres. Una acumulación más alta de grasa en las extremidades inferiores, comparada con la del tronco, parece tener un riego más bajo de ECV y sus factores de riesgo, incluso con la presencia de grasa en la región abdominal, además este efecto es más fuerte en mujeres comparadas con los hombres.

ABSTRACT

O presente artigo teve como objetivo descrever o histórico da inserção da condição clínica denominada atualmente de "obesidade" nas onze revisões da Classificação Internacional de Doenças (CID), publicadas pela Organização Mundial da Saúde (OMS), entre os anos 1900 e 2018. Para tanto, buscou-se pela palavra-chave "obesity" nos documentos, realizando, posteriormente, uma descrição e uma análise da presença, modo de inserção e as mudanças ocorridas ao longo do tempo. Os resultados demonstraram que a condição já foi e continua sendo inserida como sintoma, morbidade, coREVSmorbidade, causa de mortalidade e/ou doença. Concluiu-se que há uma grande inconsistência lógica nos princípios que regem a classificação.


This article aimed at describing the history of insertion of the clinical condition currently referred to as "obesity" in the eleven revisions of the International Classification of Diseases (ICD) published by the World Health Organization (WHO) between 1900 and 2018. For this purpose, a search for the keyword obesity was performed in the documents, with subsequent description and analysis of the presence, mode of insertion, and changes occurring over time. The results demonstrated that the condition has been and continues to be inserted as symptom, morbidity, comorbidity, cause of mortality and/or disease. It can be concluded that there is a massive logical inconsistency in the principles that govern the classification.

ABSTRACT

| INTRODUÇÃO: O excesso de gordura corporal causa alterações metabólicas complexas que acentuam na patogênese e progressão da doença renal crônica (DRC). Além disto, os aspectos comportamentais negativos, como sintomas depressivos e o sedentarismo, são comuns e podem estar associados ao acúmulo de gordura corporal em pacientes que realizam tratamento em hemodiálise (HD). OBJETIVO: Verificar a associação entre os sintomas depressivos e a gordura corporal em pacientes com DRC em HD. MÉTODO: Trata-se de um estudo transversal de um centro clínico de HD em Brasília−DF. Trinta e nove pacientes foram incluídos (59,3±16,7; idade). A composição corporal foi avaliada por meio de bioimpedância tetrapolar. O inventário de depressão de Beck foi empregado para mensurar os sintomas depressivos. Para analisar a associação entre os sintomas depressivos e a gordura corporal foi adotado o teste de correlação de Spearman. RESULTADOS: Foi observado uma prevalência de depressão de 17,9%. Os sintomas depressivos foram positivamente correlacionados com a gordura corporal (r = 0,42; p = 0,008). CONCLUSÃO: Em nossos resultados, confirmamos que os sintomas depressivos estão associados à gordura corporal em pacientes com DRC em HD. Estes achados demonstram-se importantes para a prática clínica dos profissionais de saúde, sobretudo, nos aspectos dietéticos e psicológicos em pacientes com DRC, de forma que iniciativas de diagnóstico, prevenção e tratamentos sejam priorizadas com o objetivo de reduzir tais condições.


INTRODUCTION: Excess body fat causes complex metabolic changes that enhance the pathogenesis and progression of chronic kidney disease (CKD). Furthermore, negative behavioral aspects such as depressive symptoms and a sedentary lifestyle are common and may be associated with the accumulation of body fat in patients undergoing hemodialysis (HD) treatment. OBJECTIVE: To verify the association between depressive symptoms and body fat in HD patients. METHODS: This is a cross-sectional study that enrolled thirty-nine patients (59,3 ± 16,7; age). The body composition was evaluated by bioimpedance tetrapolar. Beck's depression inventory was used to measure depressive symptoms. Anda, to analyze possible association between depressive symptoms and body fat, Spearman's correlation test was applied. RESULTS: A depression prevalence of 17.9% was observed. Depressive symptoms were positively correlated with body fat (r = 0.42; p = 0.008). CONCLUSION: Our results confirmed that depressive symptoms were associated with body fat in HD patients. These findings are important for the clinical practice of health professionals, especially in the dietary and psychological aspects; therefore, treatment initiatives for diagnosis, prevention are important to reduce these conditions.

ABSTRACT

La obesidad es un problema de salud pública. La comprensión de factores tanto emocionales como dietéticos relacionados a su desarrollo es fundamentales para abordar este problema. El objetivo del presente estudio fue analizar por sexo y edad la relación de la grasa corporal con la alimentación emocional (AE) y la calidad de la dieta (CD) en población universitaria. Se realizó un estudio transversal en el que participaron 367 estudiantes universitarios de medicina (65 % mujeres). El porcentaje de grasa se midió a través de bioimpedancia eléctrica. La alimentación emocional (AE) (emoción, familia, indiferencia, cultura y efecto del alimento) se obtuvo de la escala de AE y la calidad de la dieta (CD)a partir de índice de calidad de la dieta mexicana (ICMX) (suficiente, balanceada, completa, variada e inocua), mediante un cuestionario semicuantitativo de frecuencia de consumo de alimentos. Para identificar qué variables independientes explican el porcentaje de grasa corporal se utilizó la regresión lineal múltiple. Se encontraron diferencias estadísticamente significativas entre sexos, los hombres presentaron valores superiores a las mujeres en edad, peso, altura e IMC (kg/m2), mientras que las mujeres presentaron un mayor porcentaje de grasa corporal respecto a los hombres. La cultura (p=,001) y efecto del alimento (p=,006), factores de la AE, predijeron menor porcentaje de grasa corporal en hombres mayores de 20 años. Resulta necesario implementar programas de salud, que vayan encaminados a un consumo saludable de alimentos mediante actividades recreativas y con el acompañamiento de profesionales de la salud durante la universidad(AU)


Obesity is a public health problem. Understanding both emotional and dietary factors related to its development are essential to address this problem. The objective of this study was to analyze by sex and age the relationship of body fat with emotional eating (EE) and diet quality (DQ) in university population. A cross-sectional study was carried out in which 367 university medical students participated (65% women). Body fat percentage was measured through electrical bioimpedance. Emotional eating (EE) (emotion, family, indifference, culture and effect of food) was obtained from the EE scale and diet quality (DQ) from the Mexican Diet Quality Index (MDQI) (sufficient, balanced, complete, varied and innocuous), using a semi-quantitative food consumption frequency questionnaire. Multiple linear regression was used to identify which independent variables explain body fat percentage. Statistically significant differences were found between sexes, men had higher values than women in age, weight, height, and BMI (kg/m2), while women had a higher body fat percentage compared to men. Culture (p = .001) and effect of food (p = .006), factors of EE, predicted lower body fat percentage in men older than 20 years. It is necessary to implement health programs that are aimed at a healthy consumption of food through recreational activities and with the accompaniment of health professionals during university(AU)

ABSTRACT

To determine the association between serum ferritin levels, lipid profile and adiposity in school-age children. Methods: A cross-sectional study was conducted on obese and non-obese children. Weight, height, waist circumference and blood pressure were measured for all participants. Lipid profile, serum ferritin and glucose were determined and analysed through absorbance. The Spearman correlation was performed for the quantitative variables and a regression analysis was used to determine the interaction between variables. Eighty-nine children were included, with a median age of 9.0 years. Results: When comparing serum ferritin levels in normal weight group, vs. the overweight and obesity group, values were significantly higher in the latter. Serum ferritin correlated positively with BMI (Rho .282, p <0.01), waist circumference (Rho .372, p < 0.01), diastolic blood pressure (Rho .244, p < 0.05), body fat percentage (Rho .375, p < 0.001), insulin (Rho .254, p <.05) and sex (Rho .224, p <.05); and negatively with high-density lipoprotein cholesterol (Rho. -221, p< 0.05). When analysing the significant variables in a multivariate regression model, sex, body mass index, waist circumference, and body fat percentage remained statistically significant (p <0.01). Conclusion: We observed associations between serum ferritin and obesity in Mexican school aged children(AU)

Metodología: Se realizó un estudio transversal en niños obesos y no obesos. Se midieron el peso, la altura, la circunferencia de cintura y la presión arterial en todos los participantes. El perfil lipídico, la ferritina sérica y la glucosa se determinaron y analizaron mediante absorbancia. Se realizó correlación de Spearman para las variables cuantitativas y se utilizó un análisis de regresión para determinar la interacción entre las variables. Se incluyeron ochenta y nueve niños, con una edad media de 9,0 años. Resultados: Al comparar los niveles de ferritina sérica en el grupo de peso normal, frente al grupo de sobrepeso y obesidad, los valores fueron significativamente más altos en este último. La ferritina sérica se correlacionó positivamente con el IMC (Rho 0,282, p <0,01), la circunferencia de cintura (Rho 0,372, p <0,01), la presión arterial diastólica (Rho 0,244, p <0,05), el porcentaje de grasa corporal (Rho 0,375, p < 0,001), insulina (Rho 0,254, p <0,05) y sexo (Rho 0,224, p < 0,05); y negativamente con colesterol de lipoproteínas de alta densidad (Rho -0,221, p <0,05). Al analizar las variables significativas en un modelo de regresión multivariante, el sexo, el índice de masa corporal, la circunferencia de cintura y el porcentaje de grasa corporal se mantuvieron estadísticamente significativos (p <0,01). Conclusión: Observamos asociaciones entre la ferritina sérica y la obesidad en niños mexicanos en edad escolar(AU)

ABSTRACT

BACKGROUND: The effects of dietary nutrition on tail fat deposition and the correlation between production performance and the Hh signaling pathway and OXCT1 were investigated in fat-tailed sheep. Tan sheep were fed different nutritional diets and the variances in tail length, width, thickness and tail weight as well as the mRNA expression of fat-related genes (C/EBPα, FAS, LPL, and HSL) were determined in the tail fat of sheep at three different growth stages based on their body weight. Furthermore, the correlations between tail phenotypes and the Hedgehog (Hh) signaling pathway components (IHH, PTCH1, SMO, and GLI1) and OXCT1 were investigated. RESULTS: C/EBPα, FAS, LPL, and HSL were expressed with differences in tail fat of sheep fed different nutritional diets at three different growth stages. The results of the two-way ANOVA showed the significant effect of nutrition, stage, and interaction on gene expression, except the between C/EBPα and growth stage. C/EBPα, FAS, and LPL were considerably correlated with the tail phenotypes. Furthermore, the results of the correlation analysis demonstrated a close relationship between the tail phenotypes and Hh signaling pathway and OXCT1. CONCLUSIONS: The present study demonstrated the gene-level role of dietary nutrition in promoting tail fat deposition and related tail fat-related genes. It provides a molecular basis by which nutritional balance and tail fat formation can be investigated and additional genes can be identified. The findings of the present study may help improve the production efficiency of fat-tailed sheep and identify crucial genes associated with tail fat deposition.

ABSTRACT

SUMMARY OBJECTIVES Individuals living with HIV seem to be more prone to changes in the redistribution of body fat, characterized as lipodystrophy, which may occur in conjunction with metabolic diseases. In the present study, such impacts were assessed in adults with and without HIV and associated with the time of virus diagnosis and treatment with antiretroviral. METHODS A cross-sectional study with 123 adults, in which 87 had HIV and 36 without HIV, of both sexes, in outpatient follow-up at the Specialized Care Service (SAE) in Macaé-RJ. The following were made: 1) Alteration in body fat distribution, measured by anthropometric parameters and self-reported lipodystrophy; 2) Biochemical profile; 3) Association between HIV diagnosis time and antiretroviral treatment. RESULTS 54.47% (n = 67) males, 45.52% (n = 56) females, mean age 37 years. Of these 87 were people living with HIV, 29% (n = 25) had self-reported lipodystrophy, mean time of virus infection, and antiretroviral treatment (5.80 ± 4.56 and 5.14 ± 3.82 years), respectively. Patients with self-reported lipodystrophy had a greater change in body fat distribution between 3-6 years of HIV diagnosis and a negative cholesterol profile. The antiretroviral treatment time influenced total cholesterol and triglycerides, even for patients without self-reported lipodystrophy, with a further nine years under treatment. CONCLUSION In this study, the negative cholesterol profile was mainly related to antiretroviral treatment time, even for patients without self-reported lipodystrophy, and changes in body fat distribution, measured by anthropometry, was especially associated with time for HIV infection in those with lipodystrophy self-reported.


RESUMO OBJETIVOS Indivíduos vivendo com HIV parecem mais propensos às alterações na redistribuição da gordura corporal, caracterizada como lipodistrofia, podendo acontecer em conjunto com as metabólicas. No presente estudo avaliaram-se tais impactos em adultos com e sem HIV e se associou ao tempo de diagnóstico do vírus e tratamento com antirretroviral. MÉTODOS Estudo tipo transversal, com 123 adultos, no qual 87 tinham HIV e 36 sem HIV, de ambos os sexos, em seguimento ambulatorial no Serviço de Atendimento Especializado (SAE) em Macaé - RJ. Foram feitos: 1) Alteração na distribuição da gordura corporal, mensurados por parâmetros antropométricos e lipodistrofia autorreferida; 2) Perfil bioquímico; 3) Associação entre tempo diagnóstico do HIV e tratamento com antirretroviral. RESULTADOS Incluíram-se 54,47% (n=67) do sexo masculino, 45,52% (n=56) do feminino, com média de idade de 37 anos. Destes, 87 eram pessoas vivendo com HIV, 29% (n=25) possuíam lipodistrofia autorreferida; tempo médio de infecção pelo vírus e tratamento antirretroviral (5,80±4,56 e 5,14±3,82 anos), respectivamente. Os pacientes com lipodistrofia autorreferida tiveram maior alteração na distribuição da gordura corporal entre 3-6 anos de diagnóstico do HIV e um perfil colesterolêmico negativo. O tempo de tratamento com antirretroviral influenciou o colesterol total e os triglicerídeos, mesmo para os pacientes sem lipodistrofia autorreferida, com mais de nove anos sob tratamento. CONCLUSÃO Neste estudo, o perfil colesterolêmico negativo se relacionou principalmente ao tempo de tratamento com antirretroviral, mesmo para os pacientes sem lipodistrofia autorreferida e as alterações na distribuição da gordura corporal, mensuradas por antropometria, se associaram especialmente ao tempo de infecção pelo HIV naqueles com lipodistrofia autorreferida.

ABSTRACT

BACKGROUND@#Limited evidence exists regarding the relationship between central-to-peripheral fat ratio measured by dual-energy X-ray absorptiometry (DXA) and subsequent cardiometabolic risk in both pediatric and adult populations.@*METHODS@#The present cohort study investigated the relationship between DXA-measured body fat distribution and cardiometabolic parameters. The source population was 275 4th-6th graders (aged 9.6-12.6 years) in the northeast region of Japan (Shiokawa area in Kitakata). A 3-year follow-up was conducted to obtain complete information from 155 normal-weight children (87 boys and 68 girls). Normal-weight children were identified using sex- and age-specific international cut-offs for body mass index (BMI) based on adult BMI values of 25 kg/m and 18.5 kg/m, respectively. Body fat distribution was assessed using the trunk-to-appendicular fat ratio (TAR) and trunk-to-leg fat ratio (TLR) measured by DXA.@*RESULTS@#In boys, systolic blood pressure (SBP) at follow-up showed a significant relationship with TAR at baseline after adjusting for age, height, pubic hair appearance, SBP, and whole body fat at baseline (β = 0.24, P < 0.05), and SBP also showed a significant relationship with TLR after adjusting for confounding factors including whole body fat (β = 0.25, P < 0.05). In girls, there were no significant relationships between blood pressure and TAR/TLR.@*CONCLUSION@#Body fat distribution in normal-weight boys predicted subsequent blood pressure levels in adolescence. The relationship between fat distribution and blood pressure was independent of fat volume.

ABSTRACT

El propósito de este estudio fue identificar la relación entre la masa grasa expresada como porcentaje de grasa corporal (%GC) medida por el método de deuterio (D2O) e indicadores antropométricos en escolares costarricenses. Se trata de un estudio descriptivo transversal en el que participaron 54 niños y 49 niñas de 6 a 9 años. Se realizaron medidas antropométricas: peso, talla, índice de masa corporal, circunferencia de brazo, circunferencia de cintura, circunferencia abdominal, pliegue cutáneo subescapular y pliegue cutáneo tricipital. El análisis del %GC se realizó por medio del método de referencia del D2O. Se realizó una estadística descriptiva y se aplicó un análisis de coeficiente de correlación de Pearson para identificar la relación entre las mediciones antropométricas y el %GC obtenido por D2O. En el grupo de escolares, las niñas presentaron valores mayores de talla y pliegue cutáneo tricipital (p<0,05) y %GC obtenida por D2O (p<0,001). Se observó una fuerte correlación entre el %GC medido por D2O y el índice de masa corporal, la circunferencia de cintura y la circunferencia abdominal tanto en los niños como en las niñas. Se concluye que la circunferencia de cintura y la circunferencia abdominal podrían ser utilizadas conjuntamente con el IMC como herramientas para el diagnóstico de sobrepeso y obesidad en población escolar, cuando no se cuente con metodologías más precisas que determinen el %GC.


The purpose of this study was to identify the relationship between fat mass (FM) expressed as body fat percentage (%BF) measured by the deuterium method (D2O) and anthropometric indicators in Costa Rican schoolchildren. A cross-sectional descriptive study was performed and the participants were 54 boys and 49 girls of ages between six and nine years old. The anthropometric measurements recorded were weight, height, body mass index (BMI), arm circumference (AC), waist circumference (WC), abdominal circumference (AC), subscapular skinfold (SSF), and tricipital skinfold (TSF). The analysis of %BF was performed by means of D2O reference method. Descriptive statistics and the application of Pearson correlation coefficient analysis identified the relationship between anthropometric measurements and %BF obtained by D2O. From the group of schoolchildren, the girls showed greater values for height and tricipital skinfold (p<0.05) and %BF obtained by D2O (p<0.001). This study evidences a strong correlation between %BF measured by D2O and BMI, WC and AC in both girls and boys. It is concluded that WC and AC could be used together with the IMC as tools for the diagnosis of overweight and obesity in schoolchildren, when there are no more precise methodologies that determine the %BF.


O objetivo deste estudo foi identificar a relação entre a massa gordurosa (MG), expressa como percentagem de gordura corporal (%GC) medida pelo método de deutério (D2O) e indicadores antropométricos em escolas da Costa Rica. Trata-se de um estudo descritivo transversal, no qual participaram 54 meninos e 49 meninas com idade entre seis e nove anos. Foram realizadas medidas antropométricas: peso, tamanho, índice de massa corporal (IMC), circunferência do braço (CB), circunferência da cintura (CC), circunferência abdominal (CA), prega cutânea subescapular (PCS) e prega cutânea tricipital (PCT). A análise da %GC foi realizada pelo método de referência D2O, realizou-se uma estatística descritiva e foi aplicada análise coeficiente de correlação de Pearson para identificar a relação entre as medições antropométricas e a %GC obtida por meio do D2O. No grupo de escolares, as meninas apresentaram maiores valores de estatura e PCT (p<0,05) e %GC obtida por D2O (p<0,001). Observou-se uma importante correlação entre %GC medida por D2O e IMC, CC e CA tanto nos meninos quanto nas meninas. Conclui-se que a CC e a CA poderiam ser utilizadas conjuntamente com o IMC como ferramenta para o diagnóstico de sobrepeso e obesidade em população escolar, quando não se conte com metodologias mais precisas que determinem o %GC.

ABSTRACT

ABSTRACT Objective To investigate the associations among visceral adiposity index (VAI), lipid accumulation product (LAP), body fat percentage (%), and android/gynoid ratio (A/G ratio) in women with polycystic ovary syndrome (PCOS) and verify if the parameters representative of visceral obesity correlate with and exhibit the same frequency as body composition variables; anthropometric indices; and metabolic, hormonal, and inflammatory parameters. Subjects and methods This was a cross-sectional study that included 94 women with PCOS. Hormonal, metabolic, and inflammatory parameters were analyzed in all women. Free androgen index (FAI) and homeostasis model assessment (HOMA-IR), as well as LAP, VAI, and anthropometric indices, were calculated. The regions of interest (ROIs) in body composition and body composition indices were evaluated using a dual X-ray absorptiometry (DXA). Overall, 32 variables were selected as markers of body fat distribution. Results Among the 32 markers evaluated, 29 correlated with LAP, whereas 25 correlated with VAI, 19 with body fat (%), and 30 with A/G ratio. Additionally, some markers correlated with the four adiposity indices evaluated: ROIs, except for total mass and leg fat (%); body composition (body mass index, waist circumference, and hip circumference) indices; fasting insulin; and C-reactive protein. Conclusion LAP and VAI may be sensitive measures for screening and preventing metabolic syndrome and insulin resistance in PCOS, with LAP being more sensitive than VAI, and the A/G ratio may be more sensitive than body fat percentage.

ABSTRACT

Abstract Objective: To assess whether the indicators of weight status body mass index and waist-to-height ratio are similar to body fat percentage to identify obese children and adolescents with unfavorable lipid profile. Methods: This was a cross-sectional study involving 840 children and adolescents (6-18 years). The same individuals were classified as non-obese (<P95) or obese (≥P95) according to body fat percentage and indicators of weight status, body mass index, and waist-to-height ratio. Body fat percentage was obtained by multi-frequency bioelectrical impedance. Linear association between obesity and increased lipid fractions was tested by ANCOVA. Normal distribution curves of non-HDL cholesterol were designed for obese and non-obese. To provide the proportion of obese individuals with elevated non-HDL-c across all indicators, Z-score was calculated. Results: Obese boys presented higher non-HDL cholesterol when compared with those non-obese, classified by body mass index (107 ± 28 vs. 94 ± 25 mg/dL, p = 0.001), waist-to-height ratio (115 ± 29 vs. 94 ± 25 mg/dL, p < 0.001) and body fat percentage (119 ± 33 vs. 94 ± 24 mg/dL, p < 0.001). Differently, obese girls presented with higher non-HDL cholesterol when compared with those non-obese only according to the body fat percentage classification (118 ± 24 vs. 96 ± 26 mg/dL, p = 0.001). A large shift to the right in the distribution curve of non-HDL cholesterol among obese girls compared with non-obese was observed only when body fat percentage was used to discriminate between obese and non-obese. Conclusion: Body fat percentage was better than the indicators of weight status to identify children and adolescents with unfavorable lipid profile, mainly among girls.


Resumo Objetivo: Investigar se os indicadores da condição do peso, índice de massa corporal e razão cintura/estatura são semelhantes ao percentual de gordura corporal para identificação de crianças e adolescentes obesos com perfil lipídico desfavorável. Métodos: Estudo transversal que envolveu 840 crianças e adolescentes (6‐18 anos). Os mesmos indivíduos foram classificados em não obesos (p < 95) ou obesos (p ≥ 95) de acordo com o percentual de gordura corporal e os indicadores da condição do peso, índice de massa corporal e razão cintura/estatura. O percentual de gordura corporal foi obtido por bioimpedância multifrequencial tetrapolar. A associação linear entre obesidade e aumento das frações lipídicas foi tesada por ANCOVA. As curvas de distribuição normal de colesterol não HDL foram construídas para obesos e não obesos. Para fornecer a proporção de indivíduos obesos com colesterol não HDL elevado para todos os indicadores, o escore z foi calculado. Resultados: Os meninos obesos apresentaram maior colesterol não HDL em comparação com não obesos de acordo com a classificação fornecida pelo índice de massa corporal (107 ± 28 em comparação com 94 ± 25 mg/dL, p = 0,001), razão cintura/estatura (115 ± 29 em comparação com 94 ± 25 mg/dL, p < 0,001) e percentual de gordura corporal (119 ± 33 em comparação com 94 ± 24 g/dL, p < 0,001). Diferentemente, as meninas obesas apresentaram maior colesterol não HDL em comparação com as não obesas, somente de acordo com a classificação fornecida pelo percentual de gordura corporal (118 ± 24 em comparação com 96 ± 26 mg/dL, p = 0,001). Um grande deslocamento para a direita na curva de distribuição de colesterol não HDL entre meninas obesas em comparação com não obesas foi observado somente quando o percentual de gordura corporal foi utilizado para discriminar obesas e não obesas. Conclusão: O percentual de gordura corporal é melhor do que os indicadores da condição do peso na identificação de crianças e adolescentes com perfil lipídico desfavorável, principalmente entre meninas.

ABSTRACT

BACKGROUND: Although the involvement of obesity in metabolic disorders is well known, leg fat depot influences on albuminuria have not been determined. METHODS: This population-based, cross-sectional study used a nationally representative sample of 2,076 subjects aged ≥20 years from the Korea National Health and Nutrition Examination Surveys of 2008 to 2011. The ratio of leg fat to total fat (LF/TF ratio) was assessed by dual X-ray absorptiometry, and albuminuria was defined as more than one positive dipstick test or an albumin-to-creatinine ratio of ≥30 mg/g. RESULTS: Individuals whose LF/TF ratio was in the lowest tertile showed a higher proportion of albuminuria than those in the highest tertile (odds ratio [OR], 2.82; 95% confidence interval [CI], 2.01 to 3.96; P<0.001). This association was observed in both sexes, all age groups, and all subgroups stratified by body mass index, waist circumference, homeostasis model assessments of insulin resistance, and the presence of metabolic syndrome (all, P<0.05). Multiple logistic regression analyses also demonstrated that the lowest LF/TF ratio was independently associated with albuminuria risk (OR, 1.55 to 2.16; all, P<0.05). In addition, the risk of albuminuria was higher in sarcopenic individuals with lower LF/TF ratios than in the highest LF/TF ratio subjects without sarcopenia (OR, 3.73; 95% CI, 2.26 to 6.13). CONCLUSION: A lower LF/TF ratio was associated with an increased risk of albuminuria independent of obesity, insulin resistance, and metabolic syndrome, and when combined with sarcopenia, the albuminuria risk synergistically increased. Hence, our findings may have implications to improve risk stratification and recommendations on body fat distribution in the general population.

ABSTRACT

Recent data suggest that subclinical atherosclerosis is more related to visceral adipose tissue distribution than to overall fat mass. Both perirenal fat and epicardial fat are visceral fat depots surrounding the kidneys and the myocardium, respectively, which can be easily assessed by ultrasound. Their clinical relevance in children is largely unknown. This review describes studies relating perirenal and epicardial fat to cardiovascular disease or carotid intima-media thickness (cIMT), a well-established surrogate for subclinical atherosclerosis, and discusses this in context with our own data from children. In adults, both perirenal and epicardial fat are useful biological markers of visceral obesity. The former has been related to hypertension in overweight subjects and with atherosclerosis in patients with human immunodeficiency virus. The latter was associated with several metabolic syndrome components and with calcification of the carotid artery. In healthy prepubertal children, both epicardial and perirenal fat thickness, rather than total body fat mass, were related to cIMT. Ultrasonography measures of perirenal and epicardial fat are related to atherosclerosis in adults and may be convenient tools for the assessment of cardiometabolic risk in children.

ABSTRACT

BACKGROUNDS/OBJECTIVES: Cancer treatment may lead to significant body composition changes and affect growth and disease outcomes in pediatric cancer patients. This prospective study aimed to evaluate short- and long-term body compositions changes focused on body fat during the first year of cancer treatment in children. SUBJECTS/METHODS: A prospective study was conducted in 30 pediatric cancer patients (19 hematologic malignancies and 11 solid tumors) and 30 age- and sex-matched healthy controls. Anthropometric measurements and body composition analysis using whole body dual energy X-ray absorptiometry were performed at baseline and 1, 6, and 12 month(s) of cancer treatment. Kruskal-Wallis tests, Wilcoxon paired t tests, and generalized estimation equation (GEE) were applied for statistical analysis. RESULTS: At baseline, no differences in weight, height, body mass index, abdominal circumferences, body fat, and fat-free mass were observed between 30 controls and 30 pediatric cancer patients. Total fat mass (P < 0.001) and body fat percentage (P = 0.002) increased significantly during the first month, but no changes were observed from 1 to 12 months; however, no changes in the total mass were observed during the first year of cancer treatment. Meanwhile, the total fat-free mass decreased during the first month (P = 0.008) and recovered between 6 and 12 months of follow-up (P < 0.001). According to GEE analysis, there was a significant upward trend in body fat percentage during the first year, especially the first month, of cancer treatment in children with hematologic malignancies, but not in those with solid tumors. CONCLUSIONS: Our results indicate that cancer treatment is related to significant body composition changes and rapid body fat gain, particularly during the first month after initiating cancer treatment, in children with hematologic malignancies. Therefore, individualized dietary strategies to prevent excessive fat gain are needed in pediatric cancer patients for better outcomes.

ABSTRACT

ABSTRACT The aim of the present study was to verify the level of concordance between Body Adiposity Index (BAI) and Dual-energy X-ray Absorptiometry (DEXA) in the evaluation of body fat percentage in adolescents with type-1 diabetes mellitus (DM1). The sample consisted of 34 adolescents (16 boys and 18 girls) aged 10-15 years. Height and hip circumference data were collected for BAI calculation, and fat percentage was evaluated using DEXA. The Shapiro Wilk test was used to verify data normality. The Wilcoxon test was performed to compare age, anthropometric and BMI, BAI z score and DEXA between sexes. The correlation of variables (BAI vs DEXA) was evaluated by the Spearman correlation coefficient. For the analysis of residual scores, the Bland-Altman test was applied. The Kappa coefficient (k) was performed to assess the level of concordance between BAI and DEXA. Therefore, weak and non-significant correlation between BAI and DEXA in boys (r= 0.19, p= 0.46), and girls (r= 0.10, p= 0.73) was observed. Thus, weak concordance was observed (k= 0.09) for both sexes. It was concluded that BAI is not recommended to estimate fat percentage in adolescents with DM1.


Resumo O objetivo do presente estudo foi verificar o nível de concordância entre o Absortometria de Raio-x de Dupla Energia (DEXA) na avaliação do percentual de gordura de adolescentes com diabetes mellitus tipo 1 (DM1). A amostra foi constituída por 34 adolescentes (16 meninos e 18 meninas) com idades entre 10 e 15 anos. Coletaram-se os dados de estatura e circunferência do quadril para cálculo do IAC, bem como avaliação do percentual de gordura via DEXA. O teste de Shapiro Wilk foi utilizado para verificar a normalidade dos dados. O teste de Wilcoxon foi realizado para comparar as variáveis de idade, antropométricas e IMC score Z, IAC e DEXA entre sexos. A correlação das variáveis (IAC vs DEXA) foi avaliada pelo coeficiente de correlação de Spearman. Para análise dos escores residuais aplicou-se o teste de Bland-Altman. O coeficiente de Kappa (k) foi realizado para avaliar o nível de concordância entre o IAC e DEXA. Sendo assim, foi encontrada correlação fraca e não significante entre IAC e DEXA tanto nos meninos (r=0,19; p=0,46), quanto nas meninas (r=0,10; p=0,73). Dessa forma, foi possível perceber concordância fraca (k= 0,09) para ambos os sexos. Conclui-se que o IAC não é recomendado para estimar percentual de gordura em adolescentes com DM1.

ABSTRACT

Introdução: O excesso de gordura corporal está relacionado com as alterações no perfil lipídico, que, por sua vez, é considerado um importante fator de risco para doenças crônicas não transmissíveis. Objetivo: avaliar o estado nutricional, a composição corporal e verificar a associação destes com o perfil lipídico e pressão arterial de adolescentes. Material e Métodos: Foram avaliados 302 adolescentes, de ambos os gêneros, com idades entre 15 a 17 anos, de escolas públicas e privadas do município de Juiz de Fora, MG. Os participantes foram divididos em quatro grupos: grupo 1 (adolescentes eutróficos com percentual de gordura corpórea dentro da normalidade), grupo 2 (eutróficos com percentual de gordura elevado), grupo 3 (adolescentes em sobrepeso com percentual de gordura elevado) e grupo 4 (obesos com percentual de gordura elevado). Realizou-se avaliação antropométrica, de composição corporal, análise do perfil lipídico e aferição da pressão arterial. Os testes estatísticos T'Student ou ANOVA e Mann-Whitney ou Kruskall Wallis foram utilizados para comparação dos grupos, segundo a distribuição das variáveis, considerando nível de significância (p<0,05). Resultados: Notou-se que 74,83% dos avaliados apresentaram elevado percentual de gordura corporal, em sua maioria adolescentes do gênero feminino (57,97%). Mesmo eutróficos, 52,6% dos adolescentes apresentaram elevado percentual de gordura corporal. A maior alteração do perfil lipídico observada foi o colesterol total aumentado (40,3%), o HDL-C reduzido (27,8%), triglicerídeo aumentado (13,9%) e LDL-C aumentado (13,2%). Os adolescentes com excesso de gordura corporal, mesmo com IMC adequado apresentaram valores elevados de colesterol total, LDL-c, triglicerídeos e pressão arterial diastólica. Conclusão: O perfil lipídico desfavorável está mais relacionado com o percentual de gordura corporal total, do que com a classificação do estado nutricional segundo IMC. É imprescindível, portanto, a intensificação das ações de promoção da saúde a fim de reduzir os altos índices de doenças cardiovasculares no futuro.


Introduction: Excess body fat is related to changes in lipid profile, which, in turn, is considered an important risk factor for chronic noncommunicable diseases. Objective: To evaluate nutritional status, body composition and to verify their association with lipid profile and blood pressure in adolescents. Material and Methods: We have evaluated 302 adolescents of both genders, aged 15 to 17 years, from public and private schools in the city of Juiz de Fora, MG. Participants were divided into four groups: group 1 (eutrophic adolescents with normal body fat percentage), group 2 (eutrophic patients with high fat percentage), group 3 (overweight adolescents with high fat percentage), and group 4 (obese with high fat percentage). Anthropometric assessment, body composition, lipid profile analysis and blood pressure measurement were performed. Statistical tests T'Student or ANOVA and Mann-Whitney or Kruskall Wallis were used to compare groups according to the distribution of variables, considering significance level (p<0.05). Results:Noticed that 74.83% of the subjects had a high percentage of body fat, mostly female adolescents (57.97%). Even eutrophic, 52.6% of adolescents had a high percentage of body fat. The largest change in lipid profile was increased total cholesterol (40.3%), reduced HDL-C (27.8%), increased triglyceride (13.9%) and increased LDL-C (13.2%). The adolescents with excess body fat, even with adequate BMI, presented high values of total cholesterol, LDL-c, triglycerides and diastolic blood pressure. Conclusion: The unfavorable lipid profile is more related to the percentage of total body fat than to the nutritional status classification according to BMI. Therefore, intensification of health promotion actions is essential in order to reduce the high rates of cardiovascular disease in the future.

ABSTRACT

Abstract Percentile indicators, aided in its development by biomedical engineering, relative to body fat distribution in adolescents are able to help health professionals in better diagnosing overweight and obesity. The aim of this study was to calculate percentile values to body fat in adolescents aged between 12 and 17 years from the Curitiba-PR and its metropolitan region composed of 29 municipalities, having as reference method the dual energy x-ray absorptiometry (DXA) technology. After applying inclusion criteria for the adolescents, anthropometric measures of body fat and stature were taken, as well as evaluation of the body composition through DXA. The statistical analysis was grounded in the presentation of percentilic values developed by Cole and Green's LMS method, where L stands for the skewness curve, M for the mean curve and S for the variance curve. In total, 390 boys were evaluated. The fat percentage values tend to show a decrease between the ages of 12 (22.8±5.1%) and 16 years (17.9±2.9%). Moreover, for the superior percentiles: 90th and 97th re-start to increase at the age of 17 after showing a decrease in the previous years. The L, M and S parameters, altogether with the percentiles created to evaluate body fat are interesting tools to tendency and evolution analyses, as well as to enable inferences to be made about the body composition of adolescents.


Resumo Indicadores percentílicos referentes a distribuição da gordura corporal em adolescentes auxiliam profissionais da saúde em um melhor diagnóstico de sobrepeso e obesidade. O objetivo deste estudo foi calcular valores percentílicos para a gordura corporal de adolescentes com idades entre 12-17 anos de Curitiba-PR e região metropolitana formada ao todo por 29 municípios, tendo como método de referência a tecnologia de absorciometria de raios-X de dupla energia (DXA). Após a aplicação dos critérios de inclusão os adolescentes foram coletadas medidas antropométricas de massa corporal e estatura, além da avaliação da composição corporal com auxílio da DXA. A análise estatística teve como base a apresentação de valores percentílicos a partir do método LMS de Cole e Green, onde L representa a curva de assimetria, M a curva da média e S a curva da variação. Foram avaliados 390 meninos. Os valores de percentual de gordura tendem a apresentar um decréscimo entre as idades de 12 (22.8±5.1%) e 16 anos (17.9±2.9%). Além disso, para os percentis superiores: 90th e 97th voltam a crescer na faixa de 17 anos após redução nas idades anteriores. Os parâmetros L, M e S e os percentis criados para percentual de gordura são ferramentas interessantes para análises de tendência e evolução, bem como para que se façam inferências sobre a composição corporal de adolescentes.
