ABSTRACT

RESUMO Objetivo: Identificar um indicador de adiposidade abdominal de baixo custo e com maior acurácia para predizer o excesso de peso em crianças de quatro a sete anos idade. Métodos: Estudo transversal com amostra de 257 crianças de 4 a 7 anos. Os indicadores de adiposidade abdominal avaliados foram: perímetro da cintura (PC), relação cintura-estatura (RCE) e percentual de gordura central (avaliado pela técnica dual energy X-ray absorptiometry - DEXA). O excesso de peso foi classificado pelo índice de massa corporal por idade (IMC/I). Nas análises, estimou-se a razão de prevalência (RP) pela regressão de Poisson com variância robusta e utilizou-se a curva (receiver operating characteristics ­- ROC), considerando como significância estatística p<0,05. Resultados: A prevalência de excesso de peso foi de 24,9%, e observou-se maior mediana dos indicadores de adiposidade abdominal no grupo de crianças com excesso de peso. As crianças com valores aumentados de PC (RP=4,1; IC95% 2,86-5,86), RCE (RP=5,76; IC95% 4,14-8,02) e percentual de gordura central (RP=2,48; IC95% 1,65-3,73) apresentaram maior prevalência de excesso de peso. Verificou-se, na análise de curva ROC, que o índice RCE apresentou maior área sob a curva, comparado ao PC e ao percentual de gordura central estimada pelo DEXA, na predição do excesso de peso. Conclusões: Diante dos resultados, sugere-se a utilização da RCE para triagem de crianças com excesso de peso.


ABSTRACT Objective: To identify a low-cost abdominal adiposity index that has a higher accuracy in predicting excess weight in children aged four to seven years old. Methods: A cross-sectional study with a sample of 257 children aged 4 to 7 years old. Indicators of abdominal adiposity assessed were: waist circumference (WC), waist-to-height ratio (WHR) and central fat percentage (measured by dual energy X-ray absorptiometry - DEXA). Overweight children were classified using body mass index by age (BMI/age). In the analysis, the prevalence ratio (PR) using Poisson regression with a robust variance was estimated, and a receiver operating characteristic (ROC) curve was built, with a statistical significance of p<0.05. Results: The prevalence of overweight children was 24.9% and a higher median of all abdominal adiposity indicators was observed in the overweight group. Children with increased values of WC (PR=4.1; 95%CI 2.86-5.86), WHR (PR=5.76; 95%CI 4.14-8.02) and a central fat percentage (PR=2.48; 95%CI 1.65-3.73) had a higher prevalence of being overweight. Using the ROC curve analysis, the WHR index showed a higher area under the curve, when compared to the WC and to the central fat percentage estimated by DEXA for predicting the classification of being overweight. Conclusions: Given the results, WHR is suggested for the screening of overweight children.

ABSTRACT

Introducción: El índice de adiposidad visceral (VAI) es un método sencillo y costo-efectivo en la determinación de adiposidad visceral. El objetivo de este estudio es evaluar la relación entre el VAI con diversos factores de riesgo cardiovascular, variables sociodemográficas y hábitos psicobiológicos en la población adulta de la ciudad de Cuenca, Ecuador. Materiales y métodos: Se realizó un estudio descriptivo transversal en 318 individuos adultos seleccionados mediante muestreo aleatorio y multietápico, a quienes se les realizó evaluación clínica, evaluación antropométrica y de laboratorio. El VAI se determinó utilizando las fórmulas propuestas que emplean circunferencia abdominal, el índice de masa corporal, los triacilglicéridos y HDL-C. Se realizó un modelo de regresión logística múltiple para determinar los principales factores asociados a adiposidad visceral en sus valores más elevados. Resultados: En los 318 individuos, el promedio del VAI fue 2,57 (1,66-3,94), con valores más elevados para el sexo femenino. En el modelo de regresión logística múltiple, los factores de riesgo significativos para VAI moderado-alto fueron: la edad (> 60 años: OR = 3,87; IC del 95%: 1,15-12,96; p = 0,03), el consumo calórico, la glucemia alterada en ayuno y la actividad física en ocio. Conclusión: El VAI es un método útil para definir a aquellos sujetos con adiposidad visceral en nuestra región. La edad, el consumo calórico diario y la glucemia alterada en ayuno son los principales factores asociados con los valores más elevados delíndice, mientras que la actividad física durante el ocio representó un factor protector para clasificar a los sujetos en los estadios más avanzados.


Introduction: The visceral adiposity index (VAI) is a simple and cost effective method for the determination of visceral adiposity. The objective of this study is to evaluate the relationship between VAI and different cardiovascular risk factors, sociodemographic variables, and psychobiological habits in the adult population of the city of Cuenca, Ecuador. Materials and methods: A descriptive cross-sectional study was performed on 318 adult individuals selected by multistage random sampling, who underwent a clinical, anthropometric and laboratory evaluation. VAI was determined using the proposed formula that used abdominal circumference, body mass index, triglycerides, and HDL-Cholesterol. A multiple logistic regression model was used to determine the main factors associated with the highest values of visceral adiposity. Results: The mean VAI was 2.57 (1.66-3.94) in the 318 individuals studied, with higher values for females. In the multiple logistic regression model, significant risk factors for moderatehigh VAI were: age (>60 years: OR = 3.87, 95% CI: 1.15-12.96, P=.03), calorie intake, impaired fasting glucose, and leisure time physical activity. Conclusion: VAI is a useful method to define those subjects with visceral adiposity in our region. Age, daily calorie intake, and impaired fasting glucose are the main factors associated with higher index values, while leisure time physical activity was a protective factor for classifying subjects in the more advanced stages.

ABSTRACT

Aim: Visceral obesity is one of the most intensely researched cardiometabolic risk factors in recent years; nonetheless, its accurate assessment remains a challenge in regions were socioeconomic conditions hinder the widespread use of diagnostic methods for this purpose, such as imaging tests. In this setting, Visceral Adiposity Index (VAI) may be a useful tool. Thus, the objective of this study was to determine the VAI cutoff in adult population from Maracaibo City, Venezuela. Methods: This is a descriptive, cross-sectional study with multi-staged sampling; 2026 subjects of both genders aged ≥18 years were selected from this database and had their VAI calculated. In order to determine VAI cutoffs, subsamples of metabolically healthy and sick individuals were determined, with 599 and 286 subjects, respectively. Gender-specific and general ROC curves were plotted in order to identify the most suitable cutoff according to sensitivity and specificity. Results: Median VAI in the selected sample was 1.67 (0.97-2.78). The optimal cutoff was determined to be 1.91, with 70.3% sensitivity, 70.3% specificity [AUC = 0.777 (0.745-0.808)]. No differences were found between genders. Analysis by age revealed VAI to have greater predictive power among subjects aged < 30 years (cutoff: 1.53), 78.6% sensitivity, 72.8% specificity [AUC = 0.797 (0.709-0.884)]. Conclusion: We suggest a VAI cutoff of 1.9 for define dysfunctional adiposity in our population, with age being an important factor in the epidemiologic behavior of this variable, particularly in younger individuals.


Objetivo: La obesidad central es uno de los factores de riesgo cardiometabólicos emergente más evaluado durante los últimos años, sin embargo, su medición de forma precisa resulta un reto en aquellas poblaciones cuyas condiciones económicas dificultan la realización de métodos diagnósticos complejos, como pruebas de imagen. Por ello el objetivo de este estudio es determinar el punto de corte del índice de adiposidad visceral (VAI) en sujetos adultos de la ciudad de Maracaibo, Venezuela. Métodos: Se seleccionó a 2.026 individuos de ambos sexos, mayores de 18 años, de la base de datos del Estudio de prevalencia de síndrome metabólico en la ciudad de Maracaibo, un estudio descriptivo, transversal, con muestreo multietápico. El VAI se calculó para cada sexo y para la estimación del punto corte se seleccionó a 599 sujetos sanos y 286 enfermos, realizándose curvas COR para identificar el mejor valor de acuerdo con la sensibilidad y la especificidad. Resultados: El promedio de VAI en la muestra seleccionada fue 1,67 (0,97-2,78). El punto de corte fue 1,91 (70,3% de sensibilidad y 70,3% de especificidad) con AUC = 0,777 (0,745-0,808), sin diferencias en el punto de corte según sexo. En el análisis por grupos etarios la mayor capacidad predictiva fue para el grupo < 30 años con AUC = 0,797 (0,709-0,884), con un punto de corte de 1,53 (78,6% de sensibilidad y 72,8% de especificidad). Conclusión: El punto de corte indicado para VAI en nuestra población es de 1,9; considerando la edad como un factor importante en su comportamiento, especialmente en los grupos más jóvenes.

ABSTRACT

BACKGROUND/AIMS: Obstructive sleep apnea (OSA) is associated with an increased risk of obesity and non-alcoholic fatty liver disease (NAFLD), but it remains unclear whether the risk of NAFLD is independently related to OSA regardless of visceral obesity. Thus, the aim of the present study was to examine whether OSA alone or in combination with excessive daytime sleepiness (EDS) or short sleep duration was associated with NAFLD independent of visceral fat in Korean adults. METHODS: A total of 621 participants were selected from the Korean Genome and Epidemiology Study (KoGES). The abdominal visceral fat area (VFA) and hepatic fat components of the participants were assessed using computed tomography scans and they were then categorized into four groups depending on the presence of OSA and EDS. RESULTS: The proportions of NAFLD were 21.1%, 18.5%, 32.4%, and 46.7% in participants without OSA/EDS, with only EDS, with only OSA, and with both OSA and EDS, respectively. A combination of OSA and EDS increased the odds ratio (OR) for developing NAFLD (OR, 2.75; 95% confidence interval [CI], 1.21 to 6.28) compared to those without OSA/EDS, and this association remained significant (OR, 2.38; 95% CI, 1.01 to 5.59) even after adjusting for VFA. In short sleepers (< 5 hours) with OSA, the adjusted OR for NAFLD was 2.50 (95% CI, 1.08 to 5.75) compared to those sleeping longer than 5 hours without OSA. CONCLUSIONS: In the present study, OSA was closely associated with NAFLD in Korean adults. This association was particularly strong in those with EDS or short sleep duration regardless of VFA.

ABSTRACT

OBJETIVO: evaluar la relación de la medida del panículo adiposo abdominal con la edad y el sexo, los parámetros hospitalarios, las causas de muerte y otras enfermedades diagnosticadas. MÉTODOS: se procesaron por el Sistema Automatizado de Registro y Control de Anatomía Patológica 591 autopsias, en las que se midió el panículo adiposo abdominal a nivel del ombligo. Se crearon tres grupos de estudio según el grosor, con un número similar de casos: 0,1-1,6 cm; 1,7-2,6 cm y 2,7-9,2 cm. RESULTADOS: en el grupo de mayor grosor el promedio de edad fue de 65 años; el 33,3 % correspondió al sexo masculino y el 62,6 % al femenino. Entre las causas de muerte aumentó el infarto agudo del miocardio y disminuyó la enfermedad cerebrovascular. Los tumores malignos se incrementaron en correspondencia con el aumento del grosor del panículo adiposo. Como causas contribuyentes se encontraron la elevación de la hipertensión arterial y la diabetes mellitus. En los trastornos relacionados con el síndrome metabólico, los órganos más afectados fueron las arterias, el páncreas, el hígado, el corazón y la vesícula biliar. CONCLUSIONES: el grosor del panículo adiposo abdominal resulta un indicador apropiado para precisar la grasa abdominal y su importancia; así como su relación con la edad y el sexo, parámetros hospitalarios, causas de muerte y otras enfermedades diagnosticadas, principalmente aquellas que forman parte del síndrome metabólico.


OBJECTIVE: to evaluate the relationship among the size of panniculus adiposus abdominis , age, sex, hospital parameters, causes of death and other diagnosed diseases METHODS: using the automated system of registry and control of pathological anatomy, 591 autopsies were processed in which the abdominal fatty panniculus adiposus abdominis around the navel. Three study groups were created according to thickness, with a similar number of cases: 0.1-1.6 cm: 1.7-2.6 cm and 2.7-9.2 cm. RESULTS: the average age in the group with the thickest panniculus adiposus abdominis was 65 years: 33.3 % in males and 62.6 % in females. Acute myocardial infarction increased whereas the cerebrovascular disease decreased. The number of malignant tumors increased as the panniculus adiposus thickness increases too. The contributing causes were high blood pressure and diabetes mellitus. Regarding the metabolic syndrome related disorders, the most affected organs were arteries, pancreas, liver, heart and gallbladder. CONCLUSIONS: the panniculus adiposus abdominis thickness is an adequate indicator to measure abdominal adiposity and its importance, as well as its relationship with age and sex, hospital parameters, causes of death and other diagnosed diseases, mainly those related to the metabolic syndrome.

ABSTRACT

O objetivo deste estudo é analisar a adequação das técnicas de aferição e os pontos de corte dos indicadores antropométricos de obesidade abdominal adotados no Brasil, e sintetizar os resultados observados. Trata-se de uma revisão da literatura publicada entre 1990 a 2010 e indexada nas bases de dados Medline, Lilacs e SciELO. Os critérios de inclusão dos artigos foram: artigos originais com resumos disponíveis de pesquisas de delineamento observacional ou experimental realizados no Brasil, em idioma inglês, espanhol ou português; artigos sobre avaliação de obesidade abdominal com a utilização de indicadores antropométricos de distribuição central. Foram selecionados 18 artigos, caracterizados quanto ao autor e ano de publicação, local do estudo, tipo de estudo, tamanho da amostra, idade, sexo, indicadores antropométricos, técnicas de aferição, pontos de corte e principais resultados. Verificou-se divergência entre os estudos no que diz respeito à padronização das técnicas de aferição e dos pontos de corte utilizados. Os resultados desta revisão sugerem o uso padronizado das técnicas de aferição e pontos de corte validados, a fim de facilitar a comparação dos resultados dos estudos epidemiológicos sobre obesidade abdominal e a utilização adequada na prática clínica.


The scope of this article is to assess the suitability of the measurement techniques and the cutoff points of anthropometric indicators of abdominal obesity adopted in Brazil, and summarize the results. This involves a review of the literature published from 1990 to 2010 and indexed in the MEDLINE, LILACS and SciELO databases. The inclusion criteria for articles were: original research articles with abstracts available of experimental or observational design conducted in Brazil, in English, Spanish or Portuguese; articles about assessment of abdominal obesity with the use of anthropometric indicators of central distribution. Eighteen articles characterized according to author and publication year, study site, study type, sample size, age, sex, anthropometric indicators, measurement techniques, cutoff points and main results were selected. A divergence was found between studies in terms of standardized technical procedures and cutoff points. The results of this review recommend the standardized use of the validated measurement techniques and cutoff points in order to facilitate comparison of the results of the epidemiological studies into abdominal obesity and their adequate use in clinical practice.

ABSTRACT

Introdução: A neoplasia maligna da mama é a mais frequentes entre as mulheres, respondendo, no Brasil, por 26,3 por cento de todos os cânceres no sexo feminino e por 14 por cento dos óbitos. Sabe-se que a obesidade é também uma doença crônica, que apresenta um panorama epidemiológico crescente, capaz de modificar as concentrações de hormônios esteroides, hormônios do crescimento, que envolve processos inflamatórios crônicos e de baixa intensidade os quais favorecem a proliferação celular e redução da apoptose. Portanto, é plausível que mulheres com câncer de mama que tenham excesso de peso e adiposidade apresentem maior risco para um prognóstico clínico menos favorável. Objetivo: Avaliar o papel da adiposidade sobre a oxidação e as adipocitocinas na neoplasia mamária. Material e Métodos: Estudo observacional do tipo caso-controle, com 101 mulheres com tumor de mama (Caso) e 100 mulheres sem câncer (Controle), selecionadas no Hospital Geral de Fortaleza (Fortaleza-CE), nos anos de 2011 e 2012. Realizou-se avaliações socioeconômicas, clínica (estado de menopausa, uso de terapia de reposição hormonal-TRH, história reprodutiva, amamentação, tabagismo, sedentarismo e história familiar de câncer; estadiamento clínico (EC), tamanho do tumor e presença de linfonodos comprometidos), antropométrica (peso, índice de massa corporal -IMC, circunferência da cintura - CC) e de composição corporal ( por cento Massa Gorda - por cento MG; por cento Massa Magra - por cento MM; Ângulo de fase - AF) por impedância bioelétrica. Após jejum de 12h obteve-se alíquotas de sangue e a partir do plasma analisou-se marcadores de estresse oxidativo [TBARS; LDL(-); anti-LDL(-); 8-OHdG; vitaminas antioxidantes] e adipocitocinas (leptina e adiponectina).


Introduction: Breast malignant neoplasm is more frequent among women. In Brazil, it corresponds to 26, 3 per cent of all cancers in the female gender and to 14 per cent of the causes of death. It is well known that obesity is also a chronic disease, which presents an increasing epidemiological panorama, capable of modifying the concentrations of steroids hormones, the growth hormones, which involves chronic and low-intensity inflammatory processes, enabling cellular proliferation and the reduction of apoptosis. Therefore, it is plausible that women with breast cancer who are overweight and have adiposity present a higher risk of a less favorable clinical prognosis. Objective: To evaluate the role of adiposity over oxidation and the adipokines on breast neoplasia. Material and Methods: It was an observational study of the case-control type, with 101 women with a breast tumor (Case) and 100 women without cancer (Control), selected at Hospital Geral de Fortaleza (Fortaleza-CE), in the years of 2011 and 2012. Socio-economic evaluations were accomplished, clinic (menopause, use of Hormone Replacement Therapy (HRT), reproductive history, breastfeeding, smoking, sedentarism and family-history of cancer; clinic staging (CS), size of the tumor and presence of affected lymph nodes), anthropometrics (weight, body mass index BMI, waist circumference - WC) and of body composition ( per cent Fat Mass - per cent FM; per cent Lean Mass - per cent LM; Phase Angle - PA) by bioelectrical impedance. After a 12-hour-fasting, blood aliquots were obtained and markers of oxidative stress were analyzed from the plasma [TBARS; LDL(-); ANTI-LDL (-); 8-OHdG, antioxidant vitamins] and adipokines (leptin and adiponectin).

ABSTRACT

OBJETIVO: Avaliar o estado nutricional e os fatores clínicos, laboratoriais e comportamentais associados ao excesso de peso em crianças e adolescentes sobreviventes de leucemia linfoide aguda, tratados em um centro de referência da Região Nordeste do Brasil. MÉTODOS: Estudo de série de casos com 30 sobreviventes de leucemia linfoide aguda. Entre os meses de março e setembro de 2011, foram coletados dados clínicos, comportamentais e laboratoriais. O diagnóstico antropométrico foi realizado em três ocasiões distintas: no momento do diagnóstico, no término do tratamento, e no período pós-tratamento, a partir dos índices altura/idade e índice de massa corporal/idade, segundo a Organização Mundial de Saúde. RESULTADOS: A amostra tinha idade média de 10,2 anos (DP=3,2). Observou-se que 33,3% dos sobreviventes tinham excesso de peso no início e no término do tratamento. No período pós-tratamento, encontrou-se aumento significante do escore-Z de índice de massa corporal/idade, e uma frequência de 43,3% de excesso de peso, além de 16,6% e 35,5% de obesidade abdominal por meio da circunferência da cintura e razão cintura/estatura respectivamente. O crescimento linear foi significativamente diminuído quando comparado os escores-Z de altura/idade no início e no término do tratamento. Na análise dos dados laboratoriais, obtiveram-se 52,1% com colesterol total acima do recomendado. Entretanto, 58,3%, 66,7% e 79,2% evidenciaram, respectivamente, Lipoproteína de Alta Densidade e Lipoproteína de Baixa Densidade-colesterol e triglicerídeo na faixa considerada desejável. CONCLUSÃO: Os sobreviventes de leucemia linfoide aguda analisados apresentaram maior risco para o desenvolvimento de doenças crônicas não transmissíveis uma vez que apresentam frequência importante de excesso de peso, obesidade abdominal e colesterol total elevado.


OBJECTIVE: This study evaluated the nutritional status and clinical, laboratory, and behavioral factors associated with overweight among children and adolescents survivors of acute lymphocytic leukemia treated at a reference center in Northeastern Brazil. METHODS: A case-series study was carried out with 30 survivors of acute lymphocytic leukemia. Clinical, behavioral and laboratory data were collected between March and September 2011. The anthropometric variables height-for-age and body mass index-for-age were determined on three different occasions (time of diagnosis, end of treatment, and post-treatment period), using the reference standards of the World Health Organization. RESULTS: The mean age and standard deviation of the sample was 10.2±3.2 years. A total of 33.3% of the survivors were overweight at the beginning and end of treatment. In the post-treatment period, a significant increase was found in the body mass index-for-age Z-score. The frequency of excess weight was 43.3%. The frequency of abdominal obesity was 16.6% and 35.5% based on the waist circumference and waist-to-height ratio, respectively. The comparison of body mass index-for-age Z-scores before and after treatment revealed significantly stunted linear growth. The laboratory tests showed that total cholesterol was 52.1% above the upper limit. However, 58.3%, 66.7%, and 79.2% of the sample had high-density lipoprotein and low-density lipoprotein cholesterol, and triglyceride levels, respectively, within the recommended ranges. CONCLUSION: Based on the frequency of excess weight, abdominal obesity, and high total cholesterol, the study survivors of acute lymphocytic leukemia were at greater risk of developing chronic, non-communicable diseases.

ABSTRACT

OBJETIVO: O presente estudo objetivou identificar a prevalência do fenótipo cintura hipertrigliceridêmica (CHT) e avaliar sua associação com alterações metabólicas em adolescentes de baixa condição econômica. MÉTODO: Estudo transversal com amostra probabilística de 1.076 adolescentes entre 11 e 17 anos, de ambos os sexos, estudantes de escolas públicas. Os participantes foram submetidos à avaliação antropométrica (peso, altura e circunferência da cintura) e à dosagem dos níveis de colesterol total, LDL-C, HDL-C, colesterol não HDL, triglicérides (TG) e glicemia de jejum. Foram obtidas informações referentes às condições econômicas das famílias dos participantes.O fenótipo CHT foi definido pela presença simultânea da circunferência da cintura aumentada (> percentil 90 por idade e sexo) e dos níveis séricos de triglicérides elevados (> 100 mg/dL). A análise de regressão logística foi utilizada para avaliação das associações de interesse. RESULTADOS: A prevalência do fenótipo CHT foi de 7,2% entre os adolescentes, sendo mais elevada na presença de obesidade (63,4%), do colesterol não HDL (16,6%) e do LDL-C (13,7%) altos. A análise bivariada indicou que, das variáveis metabólicas, apenas a glicemia não se associou ao fenótipo CHT. A análise multivariada, ajustada por sexo e idade, indicou que o fenótipo CHT se associou positivamente com o colesterol não HDL alto (odds ratio, 7,0; IC 95% 3,9-12,6) e com o HDL-C baixo (odds ratio, 2,7; IC 95%, 1,5-4,8). CONCLUSÕES: Este estudo mostrou que o fenótipo CHT se associou com um perfil lipídico aterogênico e sugere esse fenótipo como uma ferramenta de screening que pode ser utilizada para identificar adolescentes com alterações metabólicas.


OBJECTIVE: This study aimed to identify the prevalence of hypertriglyceridemic waist (HTW) phenotype, and to evaluate its association with metabolic abnormalities in adolescents of low socioeconomic status. METHOD: This was a cross-sectional study with a random sample of 1,076 adolescents between 11 and 17 years, of both genders, from public schools. The participants underwent anthropometric measurements (weight, height, and waist circumference), and levels of total cholesterol, low-density-lipoprotein cholesterol (LDL-C), high-density-lipoprotein cholesterol (HDL-C), non-HDL cholesterol triglyceride (TG), and fasting glucose were measured. Information regarding the socioeconomic status of the participants' families was obtained. The HTW phenotype was defined by the simultaneous presence of increased waist circumference (> 90th percentile for age and gender) and serum triglyceride levels (> 100 mg/dL). A logistic regression analysis was used to evaluate the associations of interest. RESULTS: The prevalence of HTW phenotype was 7.2% among the adolescents, being higher in the presence of obesity (63.4%) and high levels of non-HDL cholesterol (16.6%) and LDL-C (13.7%). The bivariate analysis indicated that, of the metabolic variables, only blood glucose was not associated with the HTW phenotype. Multivariate analysis adjusted for age and gender indicated that the HTW phenotype was positively associated with high non-HDL cholesterol (odds ratio: 7.0; 95% CI: 3.9-12.6) and low HDL-C levels (odds ratio: 2.7; 95% CI: 1.5-4.8). CONCLUSIONS: This study demonstrated that the HTW phenotype was associated with an atherogenic lipid profile, and this phenotype is suggested as a screening tool to identify adolescents with metabolic alterations.

ABSTRACT

La circunferencia de cintura (CC) constituye una herramienta útil para identificar niños con mayor riesgo de complicaciones relacionadas con grasa abdominal. Se determinó la magnitud de obesidad central, única y combinada con sobrepeso/obesidad en infantes 1-5 años de edad. También se identificaron valores percentilares suavizados de CC específicos para edad y sexo, y se compararon con datos disponibles de otros países. Se realizó un estudio transversal en niños de 8 guarderías en Monterrey, México (n=903; 431 niños y 472 niñas). Debido a que el riesgo por obesidad abdominal inicia con CC en percentil 75, se consideraron dos puntos de corte, percentil 75 y 90. Se definió sobrepeso con base en índice de masa corporal para edad y sexo en percentil 85-94; y obesidad, en percentil ≥95. El análisis consistió de prevalencias puntuales e intervalos de confianza de 95%. El software LMS Chart Maker Light se utilizó para suavizar los valores percentilares de CC. La media de edad de la población fue 2,7±1,0 años. Los mexicanos registraron diferencias de 1 cm de CC más que los afro-americanos; y hasta 4 cm menos que los méxico-norteamericanos. La combinación de obesidad central con CC percentil ≥75 con sobrepeso/obesidad, fue 25,1% (IC95% 22,3-28,0) y única 15,4% (IC95% 13,0-17,8). La prevalencia de obesidad abdominal única con CC percentil ≥90, fue de 4.4% (IC95% 3.0, 5.8). Las estancias infantiles representan una oportunidad para desafiar la obesidad central. La CC puede ser utilizada desde edad temprana para tamizaje y atención a niños con mayor riesgo cardiovascular.


Central: single and combined with overweight/ obesity in preeschool Mexican children. Waist circumference (WC) is a useful measure for identifying children at higher risk of complications related with abdominal fat. We determined the magnitude of central adiposity, single and combined with overweight and obesity in infants 1-5 years old. We also identified smoothed age-and sex-specific WC percentile values, which were compared with other countries available data. This was a cross-sectional study in children of 8 day care centers located in Monterrey, Mexico (n=903, 431 boys and 472 girls). Because the risk due to abdominal obesity begins at WC percentile ≥75, we considered two thresholds, percentile 75 y 90. Overweight was defined based on body mass index at percentile 85-94 for age and sex; and obesity, at percentile ≥95. Analysis consisted of point prevalence and 95% confidence intervals. The LMS Chart Maker Light software was used for smoothing WC percentile values. The study population mean age was 2.7±1.0 years. Mexican children’s WC was 1 cm above that of Afro-American; and it was up to 4 cm below that Mexican-American. Prevalence of central obesity with WC at percentile 75 combined with overweight/obesity was 25.1% (95%CI 22.3-28.0) and single, 15.4% (95CI% 13.0- 17.8). Prevalence of single abdominal obesity with WC at percentile ≥90 was 4.4% (IC95% 3.0, 5.8). Day care centers represent a key opportunity for defying central obesity. WC can be used since early age for screening and caring children at higher cardiovascular risk.

ABSTRACT

Introducción. La obesidad está asociada con factores de riesgo para enfermedades cardiovasculares y metabólicas. La obesidad central, marcador de adiposidad intraabdominal aumentada, es mejor factor de riesgo para aterosclerosis y diabetes que el índice de masa corporal (IMC), y buen predictor de riesgo de morbimortalidad cardiovascular, síndrome metabólico y diabetes. Objetivo. Estimar prevalencias de obesidad por IMC y de obesidad abdominal por circunferencia abdominal en pacientes de atención primaria en Colombia. Materiales y métodos. Como parte de un estudio internacional, 105 médicos de atención primaria elegidos al azar reclutaron consecutivamente a pacientes de 18 a 80 años, que consultaran por cualquier razón, en dos medios días especificados previamente. Se registraron edad, sexo, tabaquismo, antecedentes cardiovasculares, diabetes, altura, peso y circunferencia abdominal mediante métodos estandarizados. Se excluyeron mujeres embarazadas y quienes no quisieran participar. Resultados. Se evaluaron 3.795 pacientes, con edad promedio de 45 años (69 % mujeres). El 60,7 % de los hombres y el 53,9 % de las mujeres tenían sobrepeso u obesidad según el IMC. El 24,6 % de los hombres y el 44,6 % de las mujeres tenían obesidad abdominal (según las guías del National Cholesterol Education Program), pero las cifras cambiaban a 62,5 % y 67,0 %, respectivamente, si se consideraban las guías de la International Diabetes Federation. La obesidad, determinada por el IMC o por la circunferencia abdominal, se asoció con mayor prevalencia de diabetes, hipertensión y dislipidemia. Conclusiones. El aumento de la circunferencia abdominal es un marcador práctico y útil para enfermedades cardiovasculares y metabólicas. La prevalencia de obesidad abdominal en pacientes de atención primaria en Colombia fue alta, y más frecuente en mujeres.


Introduction. Obesity is frequently associated with risk factors for cardiovascular and metabolic diseases. Central obesity is a marker of increased intra-abdominal adiposity and a known risk factor for atherosclerosis and diabetes; it is also a good predictor of risk for coronary events, cardiovascular mortality, diabetes and metabolic syndrome. A less predictive alternate measurement is known as the body mass index (BMI). Objective. Obesity prevalence was estimated first by BMI and then by abdominal obesity (measured by waist circumference, WC) in primary care patients. Materials and methods. As part of an international study, primary care physicians recruited consecutive patients aged 18 to 80 years who consulted for any reason on two pre-specified half-days. Age, gender, smoking status and history of cardiovascular disease or diabetes were recorded. Height, weight and WC were measured using standard methods. Pregnant women and subjects unwilling to participate were excluded. Results. A total of 3,795 patients from 105 primary care centers located throughout Colombia were evaluated. The mean age was 45 years (69% females). Of these, 60.7% of males and 53.9% of females were overweight or obese according to their BMI; 24.6% of males and 44.6% of females had abdominal obesity when National Cholesterol Education Program guidelines were used, but numbers changed to 62.5% and 67.0% when the International Diabetes Federation guidelines were used. Obesity, either determined by BMI or by WC, was associated with higher prevalence of diabetes, hypertension and dyslipidemia. Conclusions. Increased waist circumference is a practical and useful marker for cardiovascular and metabolic conditions. The prevalence of abdominal obesity in Colombian primary care patients is high and more frequent in females.

ABSTRACT

OBJECTIVE: To evaluate the prevalence of risk factors for cardiovascular disease in Japanese-Brazilian subjects. SUBJECTS AND METHODS: One hundred thirty-one residents of the Mombuca community were studied. Statistical analysis was based on the X² test, Fisher's Exact test, Student's t test, and ANOVA, at a 5% significance level. RESULTS: The average age was 56.7 years-old; 76.3% had dyslipidemia, 24.4% pre-diabetes (PDM), 10.7% type 2 diabetes mellitus (T2DM), 46.6% hypertension, 52.7% abdominal obesity, and 35.8% metabolic syndrome (MS). There were significant correlations between HOMA-IR and MS diagnosis and obesity, while HOMA-β levels were decreased in T2DM and PDM. The ankle-brachial index was positive for peripheral artery disease in 22.3% of the individuals. Electrocardiograms did not show increased evidence of myocardial ischemia. CONCLUSION: Subjects of this community are exposed to major cardiovascular risk factors, namely high prevalence of MS diagnoses and increased HOMA-IR. Arq Bras Endocrinol Metab. 2012;56(9):608-13.

ABSTRACT

El objetivo de este estudio fue valorar el autoreporte de peso, estatura y perímetro de cintura, y comparar dicha percepción con los valores reales en estudiantes universitarios participantes de la Cohorte MESPYN, -Medellín, Salud Pública y Nutrición- de la Universidad de Antioquia (UdeA) - Colombia. Se realizó un estudio transversal a partir de la primera medición de la Cohorte MESPYN 2009-2010. La muestra incluyó estudiantes voluntarios de las diferentes áreas académicas. La autovaloración de peso, estatura y perímetro de cintura se registró antes de la toma de los datos reales. Se calcularon coeficientes de correlación intraclase (CCI) para todas las variables (α=0,05); la concordancia entre medidas reales y autoreferidas se valoró según el método de Bland y Altman. Se incluyeron 424 estudiantes voluntarios. El peso promedio real de hombres (kg) fue 67,4±10,4 y autoreportado: 67,0±11,0; en mujeres el valor real: 55,7±10,1 y autoreportado: 55,0±9,0. La estatura promedio real (m) en hombres fue 1,73±6,1 y autoreportada: 1,73±6,0; en mujeres el valor real: 1,60±5,9 y autoreportado: 1,61±6,0. En hombres el perímetro de cintura promedio real (cm) fue 76,6±8,0 y autoreportado: 75,0±14,0; en mujeres el valor real: 69,9±8,0 y autoreportado: 70,0±9,0. El CCI para peso: 0,956, IC95% (0,95; 0,97), (p<0,01); CCI para estatura: 0,953, IC95% (0,91; 0,97), (p<0,01) y CCI para perímetro de cintura: 0,593, IC95% (0,55; 0,65), (p<0,01). En conclusión, la evaluación nutricional antropométrica de estudiantes de la UdeA puede realizarse por datos autoreportados para peso y estatura, pero la evaluación de obesidad abdominal requiere la toma directa del perímetro de cintura.


Comparison of self-reported anthropometric variables and real measurement data . The objectives of this study were to evaluate self-reporting of weight, height, and waist circumference, and to compare that perception with the real measurements in college students of the MESPYN cohort -- Medellin, Salud Pública y Nutrición -- from the University of Antioquia (UdeA), Colombia. A cross-sectional study was conducted starting with the first measurement of the MESPYN Cohort 2009-2010. The sample included volunteer students from different academic areas. Self-perception of weight, height, and waist circumference were recorded before the real measurements were performed. Intraclass correlation coefficients (ICC) were calculated for all the variables, and an alpha of 0.05 was used. The concordance between real measurements and self-referred values was evaluated with the Bland and Altman method. 424 volunteer students were included. The average real weight (kg) in males was 67.4±10.4 and self-reported: 67.0±11.0; in females the real value was 55.7±10.1 and self-reported: 55.0±9.0. The average real height (m) in males was 1.73±6.1 and self-reported: 1.73±6.0; in females the real value was 1.60±5.9 and self-reported: 1.61±6.0. In males, the average real waist circumference (cm) was 76.6±8.0 and self-reported: 75.0±14.0; in females the real value was 69.9±8.0 and self-reported: 70.0±9.0. Weight ICC: 0.956, 95%CI (0.95; 0.97), (p<0.01); height ICC: 0.953, 95%IC (0.91; 0.97), (p<0.01), and waist circumference ICC: 0.593, 95%IC (0.55; 0.65), (p<0.01). In conclusion, anthropometric nutritional evaluation of UdeA students can be performed with self-reported data for weight and height, but the evaluation of abdominal obesity requires direct measurement of waist circumference.

ABSTRACT

OBJECTIVE: To evaluate insulin resistance and lipid profile in women with congenital adrenal hyperplasia (CAH) caused by classical 21-hydroxylase deficiency (21OHD), and their association with body mass index (BMI) and corticosteroid dosage. SUBJECTS AND METHODS: We assessed BMI, waist circumference, current glucocorticoid dosage, glucose, insulin and lipid profile in eighteen young women (mean ± SD, 19.3 ± 3.0 years) with 21OHD CAH. RESULTS: BMI was normal in 12 patients, 5 of them were overweight, and 1 was obese. Waist circumference was high in 7 patients. Fasting insulin and HOMA-IR were elevated in seven and eight patients, respectively. Total cholesterol and triglycerides were high in only two patients, and HDL-cholesterol was low in four. Insulin resistance was not associated with BMI, waist circumference or glucocorticoid dose. CONCLUSIONS: Young women with 21OHD CAH had infrequent dyslipidemia, but had a higher prevalence of insulin resistance and central obesity, that were independent of BMI or corticosteroid dosage.


OBJETIVO: Avaliar a presença de resistência insulínica e dislipidemia em mulheres com hiperplasia adrenal congênita (HAC) por deficiência da 21-hidroxilase (21OHD) e investigar a associação com índice de massa corporal (IMC) e dose de glicocorticoide prescrita. PACIENTES E MÉTODOS: Em 18 mulheres jovens (média ± DP, 19,3 ± 3,0 anos), avaliamos IMC, circunferência abdominal, dose de glicocorticoide, glicemia, insulinemia e perfil lipídico. RESULTADOS: O IMC foi normal em 12 pacientes; 5 apresentavam sobrepeso e 1 apresentou obesidade. Circunferência abdominal estava aumentada em 7 pacientes. Insulinemia de jejum e HOMA-IR estavam elevados em 7 e 8 pacientes, respectivamente. Apenas 2 pacientes apresentaram aumento de colesterol total ou de triglicérides e 4, diminuição dos níveis de HDL-colesterol. Resistência insulínica não apresentou associação com IMC, circunferência abdominal ou dose de glicocorticoide prescrita. CONCLUSÃO: Mulheres jovens com CAH 21OHD apresentaram pouca dislipidemia, mas tiveram alta prevalência de resistência insulínica e obesidade central, independentemente do IMC e da dose de glicocorticoide prescrita.

ABSTRACT

OBJETIVO: Este estudo comparou parâmetros antropométricos e de resistência à insulina de indivíduos sem e com síndrome metabólica (SM), subestratificados pela presença de anormalidades glicêmicas. SUJEITOS E MÉTODOS: Foram incluídos 454 indivíduos (66 por cento mulheres, 54 por cento brancos), sendo 155 alocados para o grupo 1 (sem SM, sem anormalidade glicêmica), 32 para o grupo 2 (sem SM, com anormalidade glicêmica), 104 no grupo 3 (com SM, sem anormalidade glicêmica) e 163 no grupo 4 (com SM e anormalidade glicêmica). Os grupos foram comparados por ANOVA. RESULTADOS: Os grupos com SM (3 e 4) apresentaram os piores perfis antropométrico e lipídico; no grupo 2, apesar de glicemias significantemente mais elevadas, as médias das variáveis antropométricas e lipídicas não diferiram do grupo 1. Os maiores valores médios de HOMA-IR foram encontrados nos grupos com SM, enquanto o grupo 2 apresentou o menor HOMA-β. A trigliceridemia foi a variável metabólica com coeficientes de correlação mais elevados com a antropometria. Porém, as correlações mais fortes foram da circunferência da cintura (r = 0,503) e da razão cintura-altura (r = 0,513) com o HOMA-IR (p < 0,01). CONCLUSÃO: Nossos achados revelam que, em amostra da população brasileira, qualquer das medidas antropométricas identifica indivíduos com SM, mas não parece capaz de diferenciar aqueles com distúrbio glicêmico. Reforçamos a relação mais forte das medidas de adiposidade central com resistência à insulina, sugerindo utilidade da razão cintura-altura. É possível que componente autoimune contribua para o comprometimento do metabolismo glicídico dos indivíduos do grupo 2.


OBJECTIVE: This study compared anthropometric measurements and insulin resistance indexes of individuals with or without metabolic syndrome (MS), stratified by the presence of glycemic abnormalities. SUBJECTS AND METHODS: 454 individuals (66 percent women, 54 percent Caucasians) were included, being 155 allocated to group 1 (without MS, without glycemic abnormality), 32 to group 2 (without MS, with glycemic abnormality), 104 to group 3 (with MS, without glycemic abnormality), and 163 to group 4 (with MS, with glycemic abnormality). Groups were compared by ANOVA. RESULTS: Those with MS (3 e 4) showed the worst anthropometric and lipid profiles; in group 2, despite higher plasma glucose levels, the mean values of anthropometric variables and lipids did not differ from group 1. The highest mean values of HOMA-IR were found in the groups with MS, while group 2 showed the lowest HOMA-β. Triglyceride was the metabolic variable with the highest correlation coefficients with anthropometry. However, the strongest correlations were those of waist circumference (r = 0.503) and waist-to-height ratio (r = 0.513) with HOMA-IR (p < 0.01). CONCLUSION: Our findings indicate that, in a sample of the Brazilian population, any anthropometric measure identifies individuals with MS, but such measurements seem to be unable to differentiate those with glycemic disturbance. We reinforce the strongest relationship of measures of central adiposity with insulin resistance, suggesting utility for the waist-to-height. An autoimmune component may be contributing to the deterioration of glucose metabolism of individuals from group 2.

ABSTRACT

FUNDAMENTO: A obesidade abdominal é importante fator de risco cardiovascular e, juntamente com as dislipidemias, a intolerância a glicose e a hipertensão arterial, compõe a síndrome metabólica. OBJETIVO: Verificar a prevalência de obesidade abdominal e fatores associados em hipertensos. MÉTODOS: Estudo transversal com hipertensos de 20 a 79 anos cadastrados em uma Unidade Saúde da Família do município de Londrina, Paraná. A obesidade abdominal foi identificada por meio da relação cintura-quadril (RCQ) e da circunferência abdominal (CA), conforme pontos de corte recomendados pela Organização Mundial de Saúde (RCQ > 1,0 e CA > 102 cm para homens, e RCQ > 0,85 e CA > 88 cm para mulheres). RESULTADOS: Entre os 378 entrevistados, a prevalência de obesidade abdominal identificada pela RCQ foi de 65,3 por cento nos adultos e 68,1 por cento nos idosos, sendo de 87,9 por cento no sexo feminino e de 30,2 por cento no masculino (p < 0,001). Nas mulheres, a RCQ elevada esteve associada ao relato de colesterol aumentado, não realização de atividade física regular, ausência de trabalho remunerado e baixa escolaridade. Não houve associação de RCQ elevada com quaisquer variáveis no sexo masculino. A circunferência abdominal elevada esteve presente em 66,8 por cento dos adultos e 64,3 por cento dos idosos, também com diferenças entre os sexos (p < 0,001). A CA elevada mostrou-se associada, no sexo feminino, ao diabete e ao não tabagismo, e, entre homens, ao diabete e à não realização de atividade física regular. CONCLUSÃO: Esses resultados mostram uma alta prevalência de obesidade abdominal, especialmente no sexo feminino, reforçando a necessidade de estratégias que promovam a diminuição da obesidade abdominal entre hipertensos.


BACKGROUND: Abdominal obesity is an important cardiovascular risk factor and, along with dyslipidemia, impaired glucose tolerance and hypertension, it makes up the metabolic syndrome. OBJECTIVE: To investigate the prevalence of abdominal obesity and associated factors in hypertensive patients. METHODS: Cross-sectional study with hypertensive patients aged 20 to 79 registered in a Family Health Unit in the city of Londrina, Paraná. Abdominal obesity was found through waist-hip ratio (WHR) and waist circumference (WC) according to the cutoff points recommended by the World Health Organization (WHR > 1.0 and > WC 102 cm for men and WHR > WC 0.85 and > 88 cm for women). RESULTS: Among 378 respondents, the prevalence of abdominal obesity determined by WHR was 65.3 percent in adults and 68.1 percent in the elderly, and 87.9 percent in females and 30.2 percent in males (p <0.001). In women, WHR was associated with reports of high cholesterol, failure to perform regular physical activity, lack of paid work and low education. There was no association of WHR with any variables in males. High waist circumference was present in 66.8 percent of adults and 64.3 percent of elderly patients, also with differences between sexes (p <0.001). High waist circumference was associated, in women, to diabetes and to nonsmoking, and in men, to diabetes and to physical inactivity. CONCLUSION: These results show a high prevalence of abdominal obesity, especially among women, reinforcing the need for strategies to reduce abdominal obesity among hypertensive patients.

ABSTRACT

FUNDAMENTO: A obesidade abdominal apresenta elevada prevalência em mulheres com síndrome dos ovários policísticos (SOP) e está associada a um aumento do risco cardiovascular. OBJETIVO: Verificar a acurácia da circunferência da cintura (CC), da relação cintura-quadril (RCQ), da relação cintura-estatura (RCEST) e do índice de conicidade (índice C), no que se refere à detecção de fatores de risco cardiovascular (FRCV) em mulheres com SOP. MÉTODOS: Por meio de estudo transversal, foram alocadas 102 mulheres (26,5 ± 5 anos) com diagnóstico de SOP, de acordo com o consenso de Rotterdam. O colesterol total (CT), os triglicerídeos (TG), o LDL-colesterol (LDL-C), o HDL-colesterol (HDL-C), a glicemia de jejum, a glicemia após teste oral de tolerância à glicose (TOTG) e a pressão arterial (PA) foram avaliados em todas as pacientes, além das variáveis antropométricas. RESULTADOS: A relação cintura-estatura foi o marcador que apresentou correlações positivas significativas com o maior número de FRCV (PA, TG e glicemia após TOTG), destacando-se ainda a correlação negativa com HDL-C. Todos os marcadores antropométricos avaliados se correlacionaram positivamente com PA, enquanto CC e RCQ apresentaram correlação positiva também com TG. No tocante à acurácia para detecção de FRCV, os indicadores antropométricos considerados apresentaram taxas de sensibilidade superiores a 60 por cento, com destaque para a RCEST, que apresentou sensibilidade superior a 70 por cento. CONCLUSÃO: A RCEST demonstrou ser o indicador antropométrico com a melhor acurácia para a predição de FRCV. Nesse sentido, propõe-se a inclusão desse parâmetro de fácil mensuração na avaliação clínica para o rastreamento de mulheres com SOP e FRCV.


BACKGROUND: Women with polycystic ovary syndrome (PCOS) present a high prevalence of abdominal obesity, which is associated with an increased cardiovascular risk. OBJECTIVE: To verify the accuracy of the waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) and the conicity index (CI) in the detection of cardiovascular risk factors (CVRF) in women with PCOS. METHODS: The present transversal study allocated 102 women (26.5 ± 5 years) with a diagnosis of PCOS, according to the Rotterdam criteria. Total cholesterol (TC), triglycerides (TG), LDL-cholesterol (LDL-C), HDL-cholesterol (HDL-C), fasting glucose, glucose after the oral glucose tolerance test (OGTT) and blood pressure (BP) were evaluated in all patients, in addition to the anthropometric variables. RESULTS: The WHtR was the marker that presented significant positive correlations with the highest number of CVRF (BP, TG and post-OGTT glucose), whereas there was a negative correlation with HDL-C. All the evaluated anthropometric markers were positively correlated with BP, whereas WC and WHR also presented a positive correlation with TG. Regarding the accuracy for the detection of CVRF, the anthropometric markers presented a sensibility > 60 percent, especially the WHtR, which had a sensibility > 70 percent. CONCLUSION: The WHtR showed to be the most accurate anthropometric indicator for the prediction of CVRF. In this sense, we propose the inclusion of this easily-measured parameter in the clinical assessment for the screening of women with PCOS and CVRF.

ABSTRACT

INTRODUÇÃO: O índice de massa corporal (IMC) é amplamente utilizado por profissionais de saúde na avaliação do estado nutricional e do risco de mortalidade. No entanto, esse índice não fornece informações sobre a distribuição e a proporção da gordura corporal. OBJETIVO: Verificar a eficiência do IMC em identificar indivíduos com excesso de gordura corporal e com obesidade abdominal. MÉTODOS: A amostra constituiu-se de 98 homens com idade entre 20 e 58 anos. A avaliação antropométrica incluiu peso, altura, circunferência da cintura (CC) e do quadril. A composição corporal foi avaliada por bioimpedância elétrica tetrapolar. RESULTADOS: A amostra foi predominantemente jovem, 50 por cento dos indivíduos com idade entre 20 e 29 anos. O sobrepeso (IMC > 25kg/m²) e a obesidade abdominal (CC > 94cm) foram constatados em 36,7 por cento e 18,4 por cento dos homens avaliados, respectivamente. A circunferência da cintura foi a medida antropométrica que mais se correlacionou com o IMC (r = 0,884; p < 0,01) e com o percentual de gordura corporal (r = 0,779; p < 0,01). A sensibilidade do IMC, para diagnosticar indivíduos com circunferência da cintura, relação cintura-quadril (RCQ) e percentual de gordura corporal elevados, foi de 94,4 por cento, 100 por cento e 86,6 por cento, respectivamente; isso demonstra a sua adequação para estudos populacionais com o objetivo de identificar indivíduos com obesidade abdominal e/ou excesso de gordura corporal. Entretanto, na avaliação individual, o IMC não foi adequado para esse mesmo diagnóstico devido aos baixos valores preditivos positivos encontrados: 47,2 por cento para CC, 11,1 por cento para RCQ e 36,1 por cento para percentual de gordura corporal. A idade > 30 anos foi fator de risco para sobrepeso, obesidade abdominal e excesso de gordura corporal. CONCLUSÕES: Ressalta-se a importância da combinação do IMC e circunferência da cintura na avaliação do estado nutricional de homens adultos, já que a obesidade...


IINTRODUCTION: The body mass index (BMI) is widely used by health professionals in the nutritional status and risk of mortality assessment. However, this index does not provide information about the distribution and proportion of body fat. OBJECTIVE: To assess BMI efficiency in identifying individuals with surplus body fat and abdominal obesity. METHODS: The sample consisted of 98 males between 20 and 58 years of age. The anthropometrical evaluation included weight, height, waist (WC) and hip circumferences. Body composition was evaluated by tetrapolar electric bioimpedance. RESULTS: The sample was predominantly young, having 50 percent of its individuals aged between 20 and 29 years. Overweight (BMI > 25kg/m2) and abdominal obesity (CC > 94 cm) were found in 36.7 percent and 18.4 percent of the evaluated males, respectively. Waist circumference showed the strongest correlation with BMI (r=0.884; p<0.01) and with body fat percentage (r=0.779; p<0.01). BMI sensitivity to diagnose individuals with high waist circumferences, waist-to-hip ratio (WHR) and body fat percentage was 94.4 percent, 100 percent and 86.6, respectively, showing its suitability for population studies in order to identify individuals with abdominal obesity and/or surplus body fat. However, BMI was not suitable for this same diagnosis individually, due to the low positive predictive values found: 47.2 percent for WC, 11.1 percent for WHR and 36.1 percent for body fat percentage. Age > 30 years was considered a risk factor for overweight, abdominal obesity and surplus body fat. CONCLUSIONS: The importance of combining BMI and WC for verifying adult male nutritional status is emphasized, since abdominal obesity was also found in individuals who were not diagnosed with obesity by BMI.

ABSTRACT

Fundamento: A ausência de valores críticos para a identificação de risco cardiovascular entre adolescentes brasileiros representa uma importante limitação. Objetivos: Elaborar valores críticos para circunferência de cintura e analisar sua eficiência na indicação de valores elevados de pressão arterial. Métodos: Estudo transversal que avaliou 1.145 adolescentes de 11 a 17 anos (536 do sexo masculino e 609 do feminino), dos quais foram coletados valores de peso corporal, estatura, resistência, reatância, dobra cutânea tricepital, circunferência de cintura e pressão arterial (n= 334). A obesidade abdominal foi indicada por meio de valores de circunferência de cintura. Resultados: Os adolescentes obesos apresentaram valores mais altos de circunferência de cintura e, independentemente de gênero e grupo etário, houve relação significativa entre os valores de circunferência de cintura e todos os indicadores de adiposidade adotados no estudo. Os valores críticos propostos apresentaram maior sensibilidade na indicação de valores elevados de pressão arterial. Conclusões: Os valores críticos propostos para circunferência de cintura foram mais sensíveis na indicação de valores elevados de pressão arterial. Entretanto, ainda são necessários estudos para averiguar a eficiência dos mesmos na indicação de outros parâmetros clínicos e laboratoriais.


Background: The absence of critical values for the cardiovascular risk identification among Brazilian adolescents represents an important limitation. Objectives: To prepare critical values for the waist circumference and to analyze its efficiency in indicating increased values of the arterial pressure. Methods: Transversal study that evaluated 1,145 adolescents, from 11 to 17 years old (536 of the male sex and 609 of the female), their body weight values, stature, resistance, reactance, tricipital cutaneous fold, waist circumference and arterial pressure (n = 334) were collected. The abdominal obesity was indicated by waist circumference values. Results: The obese adolescents presented higher waist circumference values and, independently of the gender and age group, there was a significant relation between the waist circumference values and all the adiposity indicators adopted in the study. The proposed critical values presented higher sensibility in indicating increased values of the arterial pressure. Conclusions: The critical values proposed for the waist circumference were more sensitive in the indication of increased values of the blood pressure. However, other studies to investigate their efficacy in the indication of other clinical and laboratorial parameters are still needed.


Fundamento: La ausencia de valores críticos para la identificación de riesgo cardiovascular entre adolescentes brasileños representa una importante limitación. Objetivos: Elaborar valores críticos para el perímetro de cintura y analizar su eficiencia en la indicación de valores elevados de presión arterial. Métodos: Estudio transversal que evaluó a 1145 adolescentes de 11 a 17 años (536 de sexo masculino y 609 de femenino), de quienes se recolectaron valores de peso corporal, estatura, resistencia, reactancia, pliegue cutáneo tricipital, circunferencia de cintura y presión arterial (n= 334). La obesidad abdominal fue indicada mediante los valores de perímetro de cintura. Resultados: Los adolescentes obesos presentaron valores más altos de circunferencia de cintura e, independientemente de género y grupo etario, se observó una relación significativa entre los valores de circunferencia de cintura y todos los indicadores de adiposidad adoptados en el estudio. Los valores críticos propuestos presentaron mayor sensibilidad en la indicación de valores elevados de presión arterial. Conclusiones: Los valores críticos propuestos para la circunferencia de cintura fueron más sensibles en la indicación de valores elevados de presión arterial. No obstante, se requieren aún estudios que permitan averiguar la eficiencia de los mismos en la indicación de otros parámetros clínicos y de laboratorio.
