ABSTRACT

Introduction: Visceral fat accumulation is associated with several changes, such as, increased production of inflammatory biomarkers, especially, C-reactive protein (CRP) and fibrinogen. Anthropometric measurements for central adiposity evaluation, such as, waist circumference (WC) and sagittal abdominal diameter (SAD) have been highlighted. However, there is no consensus on the best anatomical site for measurement. Objective: To evaluate the reliability of different measurements of WC and SAD and verify their capacity to discriminate changes in inflammatory biomarkers. Method: 130 men (20-59 years) were assessed, having measurements of weight, height, WC and SAD. It was considered as the cutoff point for high-sensitivity CRP (hs-CRP) values ≥ 0.12 mg/dL and for fibrinogen the 50th percentile of the evaluated sample. Results: All measurements presented an intraclass correlation coefficient between 0.998 and 0.999. WC measured at the umbilical level (AUC=0.693±0.049) and the smallest circumference between the thorax and the hips (AUC=0.607±0.050) had greater ability to discriminate changes in concentrations of hs-CRP and fibrinogen, respectively. SAD (umbilical level) showed the better ability to detect changes in concentrations of hs-CRP (AUC=0.698± 0.049) and fibrinogen (AUC=0.625±0.049), according to the ROC analysis (p<0.05). Conclusion: WC (smallest circumference between the thorax and the hips) and SAD (umbilical level) are the anatomic sites of measurement for use in predicting the inflammatory risk in apparently health men (AU)


Introducción: La acumulación de grasa visceral se asocia con varios cambios, tales como, aumento de la producción de los biomarcadores inflamatorios, en especial, la proteína C-reactiva (PCR) y fibrinógeno. Las medidas antropométricas para la evaluación de la adiposidad central, como la circunferencia de la cintura (CC) y el diámetro abdominal sagital (DAS) se han destacado. Sin embargo, no hay consenso sobre el mejor sitio anatómico para la medición. Objetivos: Evaluar la fiabilidad de diferentes mediciones de CC y DAS y verificar su capacidad para discriminar los cambios en biomarcadores inflamatorios. Métodos: Se evaluaron 130 hombres (20-59 años). Se midió peso, estatura, circunferencia de la cintura (CC) y diámetro abdominal sagital (DAS). Se consideró como punto de corte para los valores de PCR ultrasensible (PCR-us) ≥ 0,12 mg/dL y para el fibrinógeno se utilizó el percentil 50 de la muestra evaluada. Resultados: Todas las mediciones presentaron un coeficiente de correlación intraclase entre 0.998 y 0.999. CC medida a nivel umbilical (AUC=0,693±0,049) y la circunferencia más pequeña entre el tórax y las caderas (AUC=0,607±0,050) tuvieron una mayor capacidad para discriminar los cambios en las concentraciones de PCRus y fibrinógeno, respectivamente. DAS (nivel umbilical) mostró la mejor capacidad para detectar cambios en las concentraciones de PCR-us (AUC=0,698±0,049) y fibrinógeno (AUC=0,625±0,049), de acuerdo con el análisis ROC (p<0,05). Conclusiones: CC (circunferencia más pequeña entre el tórax y las caderas) y DAS (nivel umbilical) son los sitios anatómicos de elección para su uso en la predicción del riesgo inflamatorio en hombres adultos sanos (AU)

ABSTRACT

Introduction: Epidemiological studies have shown an association between coronary heart disease and emerging cardiovascular risk factors, such as, levels of fibrinogen and high-sensitivity C-reactive protein (hs-CRP). Objectives: To verify the ability of biochemical indicators in discriminating changes in the levels of hs-CRP and fibrinogen, in apparently healthy adult men. Methods: Were evaluated 130 apparently healthy men (20-59 years), having measurement of weight and height. Biochemical measurements (lipid profile, fasting glucose, uric acid, hs-CRP and fibrinogen) were performed. Body mass index, total cholesterol/HDL-c and LDL-c/HDL-c ratios were calculated. It was considered as the cutoff point for hs-CRP values ≥ 0.12 mg/dL and for fibrinogen the 50th percentile of the evaluated sample. Results: The uric acid showed the best correlation (r = 0.325) and the higher area under the ROC curve (0.704 ± 0.054), showing greater ability to discriminate higher levels of hs-CRP (p < 0.01). The total cholesterol/HDL-c ratio (r = 0.222) and the LDL-c/HDL-c ratio (r = 0.235) showed the best correlations and the higher areas under the ROC curves (0.624 ± 0.049 and 0.624 ± 0.049) in identify higher levels of fibrinogen (p < 0.05). Conclusion: The uric acid and the total choles - terol/HDL-c and the LDL-c/HDL-c ratios showed greater ability to identify changes in the levels of hs-CRP and fibrinogen, respectively. It was suggested the use of biochemical markers in the clinical practice, in order to establish preventive action for cardiovascular disease in apparently healthy adult men (AU)


Introducción: Los estudios epidemiológicos han demostrado una asociación entre la enfermedad coronaria y nuevos factores de riesgo cardiovascular, como, los niveles de proteína C-reactiva ultrasensible (PCR-us) y fibrinógeno. Objetivos: Evaluar la capacidad de los indicadores bioquímicos en discriminar cambios en los niveles de PCRus y fibrinógeno, en hombres adultos sanos. Métodos: Se evaluaron 130 hombres (20-59 años). Se midió peso y talla. Se realizó mediciones bioquímicas (perfil lipídico, glucosa en ayunas, ácido úrico, PCR-us y fibrinógeno). Se calculó el índice de masa corporal, la relación colesterol total/HDL-c y la relación LDL-c/HDL-c. Se consideró como punto de corte para los valores de PCR-us ≥ 0,12 mg/dL y para el fibrinógeno se utilizó el percentil 50 de la muestra evaluada. Resultados: El ácido úrico mostró la mejor correlación (r = 0,325) y el área más alta bajo la curva ROC (0,704 ± 0,054), mostrando una mayor capacidad predictiva para detectar niveles más altos de PCR-us (p < 0,01). La relación colesterol total/HDL-c (r = 0,222) y la relación LDLc/HDL-c (r = 0,235) mostraron una mejor correlación y el área más alta bajo la curva ROC (0,624 ± 0,049 y 0,624 ± 0,049) en la identificación de niveles más altos de fibrinógeno (p < 0,05). Conclusiones: El ácido úrico y la relación colesterol total/HDL-c y la relación LDL-c/HDL-c mostraron una mayor capacidad predictiva para detectar cambios en los niveles de PCR-us y fibrinógeno, respectivamente. Se sugirió el uso de marcadores bioquímicos en la práctica clínica, a fin de establecer medidas preventivas para la enfermedad cardiovascular en hombres adultos sanos (AU)

ABSTRACT

Introduction: Obesity has been considered a chronic subclinical inflammation. High sensitivity C-reactive protein (hs-CRP) and fibrinogen are increasingly associated with cardiovascular risk. Objectives: To evaluate the ability of anthropometric and body composition indicators in discriminating higher levels of hs-CRP and fibrinogen. Methods: 130 men (20-59 years) were assessed, having measurement of weight, height, waist circumference (WC), hip and thigh circumferences, sagittal abdominal diameter (SAD), coronal diameter (CD) and body composition. Conicity index, waist/height ratio, body mass index, waist/hip ratio, waist/thigh ratio and sagittal index were calculated. It was considered as the cutoff point for hs-CRP values ≥ 0.12 mg/dL and for fibrinogen the 50th percentile of the evaluated sample. Results: Sagittal index (r = 0.280), waist/thigh ratio (r = 0.233) and waist/height ratio (r = 0.233) showed the best correlation with hs-CRP (p < 0.01). Conicity index (r = 0.305) and waist/height ratio (r = 0.279) showed the best correlation with fibrinogen (p < 0.01). In ROC analysis, the SAD (0.698 ± 0.049) and the conicity index (0.658 ± 0.048) had greater ability to discriminate cardiovascular risk through higher levels of hs-CRP and fibrinogen, respectively (p < 0.01). The cutoff points of 30 cm, 89.9 cm and 20.5 cm were the ones that reached largest sum between sensitivity and specificity values for the CD, WC and SAD, respectively. Conclusions: The SAD and the conicity index demonstrated a greater ability to detect higher levels of hs-CRP and fibrinogen, respectively, in apparently healthy adult men (AU)


Introducción: La obesidad ha sido considerada como una inflamación crónica subclínica. La proteína C-reactiva ultrasensible (PCR-us) y el fibrinógeno se han asociado cada vez más con el riesgo cardiovascular. Objetivos: Evaluar la capacidad, de los indicadores antropométricos y de composición corporal, en discriminar mayores niveles séricos de PCR-us y fibrinógeno. Métodos: Se evaluaron 130 hombres (20-59 años). Se midió peso, estatura, circunferencia de la cintura, de la cadera y del muslo, diámetro abdominal sagital (DAS), diámetro coronal (DC) y composición corporal. Se calculó el índice de conicidad, la relación cintura/estatura, el índice de masa corporal, la relación cintura/cadera, la relación cintura/muslo y el índice sagital. Se consideró como punto de corte para los valores de PCR-us ≥ 0,12 mg/dl y para el fibrinógeno se utilizó el percentil 50 de la muestra evaluada. Resultados: El índice sagital (r = 0,280), la relación cintura/muslo (r = 0,233) y la relación cintura/estatura (r = 0,233) mostraron una mejor correlación con la PCR-us (p < 0,01). El índice de conicidad (r = 0,305) y la relación cintura/estatura (r = 0,279) mostraron una mejor correlación con el fibrinógeno (p < 0,01). En el análisis ROC, el DAS (0,698 ± 0,049) y el índice de conicidad (0,658 ± 0,048) mostraron una mayor capacidad predictiva de riesgo cardiovascular determinado a través de mayores niveles de PCR-us y fibrinógeno, respectivamente (p < 0,01). Los puntos de corte de 30 cm, 89,9 cm y 20,5 fueron los que alcanzaron mayor sumatorio entre los valores de sensibilidad y especificidad para el DC, circunferencia de la cintura y DAS, respectivamente. Conclusiones: En hombres adultos sanos, el DAS y el índice de conicidad mostraron una mayor capacidad predictiva para detectar niveles más altos de PCR-us y fibrinógeno respectivamente.

ABSTRACT

This study aimed to investigate the relationship between stress, working conditions and the nutritional status of 53 military police officers in a Southeast city of Brazil. In order to evaluate the symptomatology and the stress phase, the Inventory of Stress Symptoms Lipp for Adults - ISSL was utilized. The assessment of the working conditions was performed by means of socio-demographic questionnaire, direct observation and interviews. The nutritional and health conditions were assessed through anthropometric measures, biochemical tests, blood pressure measurements and cardiovascular disease risk calculator. The sample is of the male gender (92.5%) and aging below 40 years old (73.6%). From these, 35.8% showed stress and 68.4% were in the resistance phase, with 31.6% almost burned out. Through the calculation of Chi-square we could find positive association between the BMI and tiredness (P = 0.0188), between the BMI and irritation (P = 0.0005) and the BMI and the appearance of nervous system problems or emotional problems (P = 0.0304), indicating that these statuses or problems could be related to work. We can conclude then, the stress is present among military police officers. No case of critical stress was found, and the stress phases identified are still susceptible to intervention.

ABSTRACT

Considering the increase in obesity worldwide and the need for studying its determinants, this study aimed to investigate the possible influence of weight and birth length in determining the nutritional status of young male adults in Viçosa-MG. One hundred individuals were evaluated in two stages of life: birth and adult age. From the records of the military recruitment database in the city, information on birth weight (BW) and birth length (BL) was searched at the maternity ward and the adult individuals were identified.The values of BMI, waist and hip circumferences, body fat calculated from BMI, fat-free body mass index and waist / hip ratio were measured in theadults. The percentage of body fat was obtained by bioelectrical impedance. Biceps skinfold (BSF), triceps skinfold (TSF), subscapular skinfold (SSSF) and suprailiac (SISF) were measured for determination of central fat (SSSF + SISF) and peripheral fat (BSF + TSF). Blood samples were collected for lipid profile analysis. Blood pressure was measured by an automatic equipment. Statistical analysis was performed using Sigma Stat 2.0 software, p <0.05. A Pearson or Spearman correlation test was used, according to the variable distribution. Means were compared by using a Student t testand ANOVA (parametric variables) or Mann Whitney and Kruskal Wallistest (nonparametric variables). The results obtained showed that 9% of the adults were obese and 39% presented increased body fat. Reduced HDL (62%) was the most frequent biochemical alteration. It was observed that individuals with BMI> 25kg/m2 and increased blood pressure had average BL values higher than the other individuals. The results suggest that BL may reflect the nutritional status in the future and thus should be considered in further studies.


Considerando el elevado aumento de la obesidad en el mundo y la necesidad de investigar sus determinantes, este estudio tuvo por objetivo averiguar una posible influencia de la talla y el peso al nacer con el estado nutricional de jóvenes adultos del sexo masculino del municipio de Viçosa-Minas Gerais - Brasil. Fueron evaluados cien individuos en dos etapas de la vida: al nacimiento y en la edad adulta. De los registros de reclutamiento militar del municipio y de los nacimientos en la maternidad local se levantaron informaciones sobre el peso (PN) y la talla (NC) al nacer y se identificaron los individuos adultos. En la fase adulta, se determinaron el índicede masa corporal (IMC), las circunferencias de cintura y cadera, el IMC libre de grasa y la relación cintura/cadera. El porcentaje de grasa corporal se obtuvo por medio de la bioimpedancia eléctrica. Se determinaron los pliegues cutáneos del bíceps (PCB), tríceps (PCT), subescapular (SST) y suprailíaco (PCSI) para la determinación de la grasa central (TSM + PCSI) y periférica (PCB + PCT). Se cogieron muestras de sangrepara análisis del perfil de lípidos. La presión arterial se midió con un sistema automático. Para el análisis estadístico (p <0,05; Sigma Stat2.0,) fue utilizado test de correlación de Pearsono Spearman, respectivamente, para las variables con y sin distribución normal; ANOVA y test t deStudent (en caso de variables paramétricas) o Mann Whitney y Kruskal Wallis (para variablesno paramétricas) fueron empleados para comparación de las medias. En la muestra evaluada, 9% de los individuos eran obesos y 39% fueron clasificados como portadores de grasa corporal aumentada. La alteración bioquímica más frecuente (62%) fue la reducción de HDL. Se observó que los individuos con IMC> 25kg/m2 y con presión arterial elevada presentan media de NC superior a los demás. Los resultados sugieren que el NC puede relacionar se al futuro estado nutricional del individuo adulto y por tanto debeser considerado en futuros estudios.


Considerando o aumento da obesidade em todo o mundo e a necessidade de se estudar seus determinantes, este trabalho teve como objetivo investigar a possível influência do peso e comprimento ao nascer na determinação do estado nutricional de adultos jovens do sexo masculino do município de Viçosa-MG. Foram avaliados cem indivíduos, em duas fases da vida: ao nascer e na vida adulta. A partir dos registros do banco de dados de alistamento militar do município, buscaram-se, na maternidade, informações sobre peso (PN) e comprimento ao nascer (CN) e identificaram-se os indivíduos, quando adultos. Na vida adulta, avaliaram-se IMC, circunferência da cintura e quadril, IMC de gordura, IMC livre de gordura e relação cintura/quadril. O percentual de gordura corporal foi obtido por bioimpedância elétrica. Aferiram-se pregas cutâneas biciptal (PCB), triciptal (PCT), subescapular (PCSE) e suprailíaca (PCSI) para determinação de gordura central (PCSE + PCSI) e periférica (PCB + PCT). Amostras de sangue foram coletadas para análise do perfil lipídico. A pressão arterial foi aferida por aparelho automático. A análise estatística foi realizada no software Sigma Stat 2.0, p < 0,05. Utilizou-se teste de correlação de Pearson ou Spearman, segundo distribuição das variáveis. O test t'Student e Anova (variáveis paramétricas) ou Mann Whitneye Kruskal Wallis (variáveis não paramétricas) foram utilizados para comparação de médias. Obteve-se, 9% de obesidade e 39% de gordura corporal aumentada. A alteração bioquímica mais frequente foi o HDL reduzido (62%).Observou-se que indivíduos com IMC > 25kg/m2 e com pressão arterial aumentada apresentaram médias de CN superior aos demais. Os resultados obtidos sugerem que o CN pode refletir no estado nutricional futuro e, desta forma, deve ser considerado em estudos posteriores.

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 correlação entre aumento de gordura visceral e de resistência à insulina coloca o diâmetro abdominal sagital e o perímetro da cintura como instrumentos potenciais para a predição de resistência à insulina. OBJETIVO: Avaliar a reprodutibilidade de diferentes aferições do diâmetro abdominal sagital e do perímetro da cintura e analisar o poder discriminante dos mesmos para predizer resistência à insulina. MÉTODOS: Foram avaliados 190 homens adultos. O diâmetro abdominal sagital (menor cintura, maior diâmetro abdominal, nível umbilical e ponto médio entre as cristas ilíacas) e o perímetro da cintura (nível umbilical, menor cintura, imediatamente acima da crista ilíaca e ponto médio entre a crista ilíaca e a última costela) foram aferidos em quatro locais diferentes. A resistência à insulina foi avaliada pelo índice HOMA-IR. RESULTADOS: Todas as medidas apresentaram correlação intraclasse de 0,986-0,999. Tanto o diâmetro abdominal sagital aferido na menor cintura (r=0,482 e AUC=0,739±0,049) como o perímetro da cintura aferido no ponto médio entre a última costela e a crista ilíaca (r=0,464 e AUC=0,746±0,05) apresentaram maiores correlações com o HOMA-IR, bem como um melhor poder discriminante para o HOMA-IR segundo a análise ROC (p<0,001). CONCLUSÃO: O diâmetro abdominal sagital e o perímetro da cintura mostraram-se altamente reprodutíveis. O diâmetro abdominal sagital (menor cintura) e o perímetro da cintura (ponto médio crista ilíaca e última costela) apresentaram melhor desempenho em predizer o HOMA-IR. Investigações em outros grupos da população brasileira devem ser realizadas para viabilizar a utilização desses indicadores de resistência à insulina na população como um todo de forma padronizada.


BACKGROUND: The correlation between the increase in visceral fat and insulin resistance makes the sagittal abdominal diameter and the waist perimeter as potential tools for the prediction of insulin resistance. OBJECTIVE: To assess the reproducibility of different measurements of the sagittal abdominal diameter and the waist perimeter and analyze the discriminating power of the measurements when predicting insulin resistance. METHODS: A total of 190 adult males were studied. The sagittal abdominal diameter (smallest girth, larger abdominal diameter, umbilical level and midpoint between the iliac crests) and the waist perimeter (umbilical level, smallest girth, immediately above the iliac crest and midpoint between the iliac crest and the last rib) were measured at four different sites. Insulin resistance was assessed by the homeostasis model of assessment-insulin resistance (HOMA-IR) index. RESULTS: All measurements presented an intraclass correlation of 0.986-0.999. The sagittal abdominal diameter measured at the smallest girth (r=0.482 and AUC=0.739±0.049) and the waist perimeter measured at the midpoint between the last rib and the iliac crest (r=0.464 and AUC=0.746±0.05) presented the highest correlations with the HOMA-IR and the best discriminating power for HOMA-IR according to the ROC analysis (p<0.001). CONCLUSION: The sagittal abdominal diameter and waist perimeter showed to be highly reproducible and the sagittal abdominal diameter (smallest girth) and waist perimeter (midpoint between the iliac crest and the last rib) presented the best performance when predicting HOMA-IR. Further studies in other groups of the Brazilian population must be carried out to allow the use of these indicators of insulin resistance in the population as a whole, following standardized procedures.

OBJETIVO: Evaluar la reproductibilidad de distintas mediciones del diámetro abdominal sagital y del perímetro de la cintura y analizar el poder discriminante de las mismas para predecir resistencia a la insulina. MÉTODOS: Se evaluaron a 190 varones adultos. El diámetro abdominal sagital (menor cintura, mayor diámetro abdominal, nivel umbilical y punto promedio entre las crestas ilíacas) y el perímetro de la cintura (nivel umbilical, menor cintura, inmediatamente superior a la cresta ilíaca y punto promedio entre la cresta ilíaca y la última costilla) se calcularon en cuatro locales diferentes. La resistencia a la insulina se evaluó por el índice HOMA-IR. RESULTADOS: Todas las mediciones presentaron correlación intraclase de 0,986-0,999. Tanto el diámetro abdominal sagital calculado en la menor cintura (r=0,482 y AUC=0,739±0,049) como el perímetro de la cintura calculado en el punto promedio entre la última costilla y la cresta ilíaca (r=0,464 e AUC=0,746±0,05) presentaron mayores correlaciones con el HOMA-IR, así como un mejor poder discriminante para el HOMA-IR según el análisis ROC (p<0,001). CONCLUSIONES: El diámetro abdominal sagital y el perímetro de la cintura se evidenciaron altamente reproductibles. El diámetro abdominal sagital (menor cintura) y el perímetro de la cintura (punto promedio la cresta ilíaca y última costilla) presentaron mejor desempeño en predecir el HOMA-IR. Investigaciones en otros grupos de la población brasileña se deben realizar para viabilizar la utilización de estos indicadores de resistencia a la insulina en la población como un todo de forma estandarizada.

Insulin resistance was assessed by the homeostasis model of assessment-insulin resistance (HOMA-IR) index. RESULTS: All measurements presented an intraclass correlation of 0.986-0.999. The sagittal abdominal diameter measured at the smallest girth (r=0.482 and AUC=0.739+/-0.049) and the waist perimeter measured at the midpoint between the last rib and the iliac crest (r=0.464 and AUC=0.746+/-0.05) presented the highest correlations with the HOMA-IR and the best discriminating power for HOMA-IR according to the ROC analysis (p<0.001). CONCLUSION: The sagittal abdominal diameter and waist perimeter showed to be highly reproducible and the sagittal abdominal diameter (smallest girth) and waist perimeter (midpoint between the iliac crest and the last rib) presented the best performance when predicting HOMA-IR. Further studies in other groups of the Brazilian population must be carried out to allow the use of these indicators of insulin resistance in the population as a whole, following standardized procedures.

ABSTRACT

OBJETIVO: Avaliar a validade de fórmulas preditivas de peso e de altura, bem como a composição corporal em homens adultos. MÉTODOS: A amostra constituiu-se de 98 homens saudáveis, com idades entre 20 e 58 anos. Para a análise das equações de estimativa de peso e altura, coletaram-se dados de peso, altura, altura do joelho, envergadura, semi-envergadura, circunferências da panturrilha e do braço e dobra cutânea subescapular. Avaliou-se a composição corporal por meio de bioimpedância elétrica. RESULTADOS: O peso estimado diferiu significantemente do peso aferido (p<0,001). Apenas a equação de estimativa de altura validada para homens brancos adultos, mostrou-se adequada para estimar a altura. Tanto a medida de envergadura (r=0,789; d=2,67; p<0,001) quanto a de semi-envergadura (r=0,790; d=2,51; p<0,001) resultaram em superestimação da altura aferida. Ao calcular o índice de massa corporal, pelo peso e altura estimados por medidas recumbentes, verificou-se que a maioria dos valores estimados superestimou o baixo peso e subestimou o sobrepeso, exceto quando a altura foi estimada pelas equações propostas para homens adultos. CONCLUSÃO: A equação de estimativa de altura validada para homens brancos adultos foi adequada para a estimativa da estatura em homens adultos jovens e observou-se que a maioria das equações avaliadas apresentaram diferenças significantes. Ressalta-se a importância da validação das equações aqui avaliadas em outros grupos populacionais, além de cautela ao utilizar peso e altura estimados.


OBJECTIVE: The objective of this study was to evaluate the validity of equations that predict weight, height and body composition in adult men. METHODS: The sample consisted of 98 healthy men aged from 20 to 58 years. In order to analyze the equations, weight, height, knee height, arm span, half-arm span, calf and arm circumference and subscapular skinfold thickness were collected. Body composition was determined by bioimpedance. RESULTS: Estimated weights were significantly different from measured weights (p<0.001). The only equation that estimated height properly was that validated for adult Caucasian men. Both arm span (r=0.789; d=2.67; p<0.001) and half-arm span (r=0.790; d=2.51; p<0.001) overestimated height. When weight and height estimates were used to calculate body mass index, underweight was overestimated and overweight was underestimated, except when height was estimated with the equations for adult Caucasian men. CONCLUSION: The equation to estimate height validated for adult Caucasian men estimated the height of adult young men properly; the other validated equations presented significant differences. It is important to validate the equations assessed in this study in other population groups, making sure to use the estimated weights and heights to calculate body mass index.

ABSTRACT

PURPOSE: To investigate the effectiveness of biochemical indicators from the plasmatic lipid profile to identify the insulin resistance (IR), assessed by the HOMA-IR index (Homeostasis Model Assessment -Insulin Resistance). METHODS: 138 healthy men (20-59 years) were evaluated. The lipid profile biochemical indicators analyzed were the following: triglycerides (TG), total cholesterol (TC), HDL-C, LDL-C, and TC/HDL-C and TG/HDL-C ratios. The percentile 75 was considered as the cut-off point for IR. Statistical analysis consisted of Spearman correlation coefficient, ROC curves and calculation of the areas under the curve (AUC). RESULT: The TG/HDL-C ratio showed the strongest correlation and the greatest AUC (r = 0.334 and AUC = 0.724 +/- 0.046, p < 0.001) respectively, followed by the HDL-C (r = -0.313 and AUC = 0.716 +/- 0.052, p < 0.01), the TG (r = 0.261 and AUC = 0.048 +/- 0.674, p < 0.01) and CT/HDL-C ratio (r = 0.259 and AUC = 0.655 +/- 0.05, p < 0.01). Results for TC and LDL-C showed no statistical significant (p > 0.05). CONCLUSION: The TG/HDL-C ratio showed the greatest ability to identify IR, proved to be an alternative and easy access instrument to assess IR in clinical practice, therefore providing diseases prevention for the adult male population.

ABSTRACT

BACKGROUND: The increase in the prevalence of excess weight among people of increasingly younger age groups may lead to the early development of cardiovascular risks. OBJECTIVE: To investigate the prevalence of the metabolic syndrome among young adults and the impact of birth conditions and nutritional status during adolescence on this disorder. METHODS: One hundred individuals were evaluated at three different stages of life. By consulting the database of people enlisted in the army reserve military service, data were collected on weight, height, and waist circumference of all draftees of 1996, 1997, and 1999 in order to analyze their nutritional status during adolescence. Using the same database, information was sought at the maternity on their birth conditions and the adult individuals were identified. Anthropometric and biochemical data were obtained from these adults. The Metabolic Syndrome (MS) was classified according to ATP III NCEP. Body fat percentage was assessed with bioelectrical impedance and the statistical analysis was performed using the Sigma Stat 2.0 software. RESULTS: Prevalence of the MS was detected in 13% of the individuals. The birth conditions showed no relationship with the syndrome. In adolescence, those individuals diagnosed with MS had greater values for weight (11 kg; p =<0.001), WC (8 cm; p < 0.001), and BMI (2.5 kg/m(2); p= 0.002). CONCLUSION: A significant part of the risk factors for cardiovascular conditions starts during childhood and adolescence, and is likely to persist throughout life; therefore, primary prevention measures are critical in the context of cardiovascular disease.

ABSTRACT

OBJECTIVE: To assess the ability of anthropometric and body composition indicators in identifying insulin resistance (IR), determining cut-off points for those showing the best efficacy. METHOD: 138 men were evaluated. Waist perimeter (WP), sagittal abdominal diameter (SAD), conicity index, body mass index (BMI), body fat percent, sagittal index, and the waist-to-height, waist-to-hip and waist-to-thigh ratios were determined. IR was assessed by the HOMA-IR index. Statistical analysis consisted of Spearman correlation coefficient and ROC (receiver operating characteristic) curves, calculating the area under the curve (AUC). RESULTS: SAD (r=0.482, AUC=0.746) and WP (r=0.464, AUC=0.739) showed stronger correlations with the HOMA-IR and greater ability to identify IR (p<0.001), being 89.3 cm and 20.0 cm the best cut-offs, respectively. CONCLUSION: The anthropometric indicators of central obesity, WP and SAD, have shown greater ability to identify IR in men. We encourage studies in women and elderly people in search of the best cut-off points for the entire population.

ABSTRACT

OBJETIVO:Validar um questionário semiquantitativo de freqüência alimentar para avaliar a ingestão dietética de adultos na cidade de Viçosa, Minas Gerais. MÉTODOS: Noventa e quatro adultos de ambos os sexos e representando diferentes níveis educacionais. Como método de referência para o estudo de validação, quatro recordatórios 24 horas foram usados com intervalos de um mês. Um questionário semiquantitativo de freqüência alimentar constituído de 58 itens alimentares foi aplicado no final do estudo. Os dados dietéticos foram calculados pelo software Diet Pro e analisados segundo diferenças de médias e estimativas de correlação de Pearson, ajustados pela energia e corrigidos pela variância intrapessoal, bem como pela classificação cruzada dos métodos. RESULTADOS: Diferenças de médias ou medianas dos nutrientes obtidos pela aplicação das metodologias referidas revelaram subestimação no questionário semiquantitativo de freqüência alimentar de micronutrientes (vitamina C, retinol e cálcio). Porém, quando avaliados pelas estimativas de correlação e corrigidos pela variância esses micronutrientes apresentaram valores adequados. Lipídio foi o único nutriente que indicou baixa consistência na avaliação dietética entre os métodos (r=0,33); e os demais nutrientes apresentaram resultados variáveis de correlação (r=0,40 a r=0,76), com média de r=0,52. A análise da correta classificação conferiu uma concordância não perfeita, mas aceitável entre os métodos. CONCLUSÃO: O questionário semiquantitativo de freqüência alimentar apresentou aceitável desempenho na avaliação do consumo alimentar habitual da maioria dos nutrientes pela população estudada. O questionário em estudo poderá ser adaptado e utilizado em outras populações, mas novo estudo de validação se faz necessário se as características da população forem diferentes.


OBJETIVE: To validate a semi quantitative food frequency questionnaire to assess the food intake of adults in the city of Viçosa, Minas Gerais. METHODS: Ninety-four adults of both genders and representing different educational levels. As a reference method for the validation study four 24 hour dietary recalls were used with intervals of one month in between. A semi quantitative food frequency questionnaire containing 58 food items was applied at the end of the study. The dietetic data was calculated using Diet Pro software and analyzed according to difference of means or medians and Pearson's correlation. The correlation coefficients were adjusted for energy and corrected for intrapersonal variance. Cross classification was used for comparing both methods. RESULTS: Differences of means or medians revealed underestimation of the semi quantitative food frequency questionnaire on determining the consumption of micronutrients (vitamin C, retinol, and calcium). However, when evaluated by the correlation coefficients and corrected for the variance, these micronutrients presented adequate values; lipid was the only nutrient that indicated low consistency in the dietary assessment among the methods (r=0.33); the other nutrients showed a correlation varying from r=0.40 to r=0.76, with a mean of r=0.52. The correct classification of the methods presented a non-perfect agreement, but acceptable among the evaluated methods. CONCLUSION: The performance of the semi quantitative food frequency questionnaire in the assessment of the habitual food intake was acceptable for most of the nutrients in the studied population. The studied questionnaire can be adapted and used in other populations, but a new validation study is needed if the characteristics of the population differ.

ABSTRACT

OBJETIVOS: Avaliar a habilidade de indicadores antropométricos e de composição corporal em identificar a resistência à insulina (RI), determinando-se os pontos de corte para os que apresentarem melhor eficácia. MÉTODOS: Foram avaliados 138 homens. Determinou-se: perímetro da cintura (PC), diâmetro abdominal sagital (DAS), índice de conicidade (IC), índice de massa corporal (IMC), percentual de gordura corporal ( por centoGC), índice sagital (IS) e relações cintura-estatura (RCE), cintura-quadril (RCQ) e cintura-coxa (RCCoxa). A RI foi avaliada pelo HOMA-IR. Utilizou-se análise de correlação e análise ROC, com determinação das áreas abaixo da curva (AUC). RESULTADOS: O DAS (r = 0,482; AUC = 0,746) e o PC (r = 0,464; AUC = 0,739) apresentaram correlações mais fortes com o HOMA-IR e maior poder discriminante para RI (p < 0,001), sendo seus melhores pontos de corte 89,3 cm e 20,0 cm, respectivamente. CONCLUSÃO: Os indicadores de obesidade central, o PC e o DAS demonstraram maior habilidade em identificar RI em homens. Encoraja-se a realização de estudos com mulheres e idosos na busca dos melhores pontos de corte para toda a população.

ABSTRACT

FUNDAMENTO: O aumento da prevalência do excesso de peso em faixas etárias cada vez mais jovens pode levar ao desenvolvimento precoce de fatores de riscos cardiovasculares. OBJETIVO: Investigar a prevalência de síndrome metabólica em adultos jovens e a influência das condições de nascimento e estado nutricional na adolescência sobre este quadro. MÉTODOS: Foram avaliados cem indivíduos, em três fases da vida. A partir dos registros do banco de dados de alistamento do Tiro de Guerra, coletou-se peso, estatura e circunferência da cintura de todos os alistados nos anos de 1996, 97 e 99, para análise do estado nutricional na adolescência. A partir dos registros do mesmo banco, buscou-se informações sobre as condições de nascimento na maternidade e identificou-se os indivíduos, quando adultos. Na vida adulta, realizou-se avaliação antropométrica e bioquímica. A classificação da síndrome metabólica (SM) se deu de acordo com proposta do NCEP-ATP III. O percentual de gordura corporal foi aferido por bioimpedância elétrica. A pressão arterial foi aferida por aparelho automático. A análise estatística foi realizada no software Sigma Stat 2.0, p<0,05. RESULTADOS: Encontrou-se prevalência de SM em 13 por cento dos avaliados. As condições de nascimento não apresentaram relação com a determinação na síndrome. Aqueles diagnosticados com SM apresentavam, na adolescência valores superiores de peso (11 kg; p =<0,001), circunferência da cintura (8 cm; p < 0,001) e índice de massa corporal (2,5 kg/m²; p= 0,002). CONCLUSÃO: Grande parte dos fatores de risco cardiovasculares tem início na infância e adolescência e tende persistir ao longo da vida, desta forma, medidas de prevenção primária são de grande importância no cenário das doenças cardiovasculares.

ABSTRACT

OBJETIVOS: Investigar a habilidade de indicadores bioquímicos do perfil lipídico plasmático em identificar resistência à insulina (RI), avaliada pelo índice HOMA-IR (Homeostasis Model Assessment - Insulin Resistance). MÉTODOS: Foram avaliados 138 homens saudáveis (20-59 anos). Analisaram-se os seguintes indicadores bioquímicos do perfil lipídico: triglicérides (TG), colesterol total (CT), HDL-C, LDL-C, e as relações CT/HDL-C e TG/HDL-C. Considerou-se o percentil 75 como ponto de corte para o índice HOMA-IR. A análise estatística constou do cálculo do coeficiente de correlação de Spearman e da construção de curvas ROC, com o cálculo das áreas abaixo da curva (AUC). RESULTADOS: A relação TG/HDL-C (r = 0.334 e AUC = 0.724 ± 0.046 p<0.001) apresentou a correlação mais forte e a maior AUC, respectivamente, seguida do HDL-C (r = -0,313 e AUC = 0,716 ± 0.052, p<0.01), dos TG (r = 0.261 e AUC = 0.674 ± 0,048; p<0,01) e da relação CT/HDL-C (r = 0.259 e AUC = 0.655 ± 0.05, p<0.01). O CT e o LDL-C não apresentaram resultados estatísticos significantes (p > 0,05). CONCLUSÃO: A relação TG/HDL-C apresentou melhor habilidade em identificar RI, representando um instrumento alternativo e de fácil acesso para a avaliação da RI na prática clínica, proporcionando intervenções de caráter preventivo de doenças na população do sexo masculino.

ABSTRACT

The prevalences of overweight / obesity are increasing worldwide, thusbecoming a public health problem. Therefore, this work aimed to investigatethe nutritional status of young adults, seeking correlations between dietaryintakevariables. One hundred healthy male individuals living in Viçosa-MGwere evaluated for BMI, waist circumference (WC) and hip circumference(HC), fat BMI, fat-free BMI and waist/hip ratio (RCQ), by using the cutoffpoints proposed by WHO (1998). The percentage of body fat (% GORD) waschecked through electric bioimpedance. The thickness of bicipital (PCB),tricipital (PCT), subscapular (PCSE) and suprailiac (PCSI) skinfolds weremeasured to determine central fat (PCSE + PCSI) and peripheral fat (PCB +PCT). Blood samples were collected for analyzing lipid profi le. Three recordson food consumption were used for investigating diet and energy intakes. A33% prevalence of excessive weight (BMI ≥ 25 kg/m2) and a 39% prevalenceof high body fat were observed. Low HDL (62%) was the most frequentalteration observed in the biochemical profi le. Energy intake was found to bepositively and signifi cantly associated with all anthropometric variables, andthe strongest correlations were observed between energy intake and weight(r=0649, p<0001), BMI (r=0649, p<0001), waist circumference (WC)(r=0587, p<0001) and hip circumference (HC) (r=0590, p<0001). The datapresented highlight the importance of investing in educational measures inorder to promote the adoption of healthy habits which prevent complicationsin the future.

ABSTRACT

This study aimed to describe the demographic and epidemiological characteristics of the elderly population, identify the area of influence of basic care in relation to the area of residence of the elderly and the rate of service use, as well as to map the demand according to the geographic location of the Basic Care Unit. The sample comprised 6,964 male and female subjects aged 60 years or more, who sought any of the outpatient public health services between May 2003 and April 2004. From this total, 64.1% were women and 35.9% men. The results show that cardiovascular diseases account for the greater part of medical consultations in the health system, with a mean of 3,576 consultations per year per elderly. Geographic mapping showed the demand for medical consultations in determinate basic care units to be related with the medical specialty available at these units. These results allow identifying the neighborhoods with the highest concentrations of specific diseases, indicating the need for insertion/redistribution of professionals between the basic care units in order to improve the quality of life of the elderly.

ABSTRACT

O objetivo deste estudo foi descrever as características demográficas e epidemiológicas da população idosa e identificar a área de influência dos serviços de atenção básica do sistema público de saúde em relação ao bairro de residência do idoso, identificar a taxa de utilização dos serviços e mapear a procura por atendimento de acordo com a localização geográfica da Unidade Básica de Saúde (UBS). Compuseram a amostra 6.964 atendimentos de saúde, prestados a 2.391 indivíduos idosos, ambos os sexos, que compareceram a um dos serviços públicos de atenção básica à saúde do município, no período de maio de 2003 a abril de 2004. Do total da amostra, 64,1 por cento são do sexo feminino e 35,9 por cento, do masculino. Os resultados mostram que as doenças cardiovasculares são as responsáveis pelo maior contingente de atendimentos no sistema de saúde. O número médio de consultas foi de 3,6 ao ano por idoso. O mapeamento geográfico permitiu visualizar que a procura por atendimento em determinadas UBS está relacionado com a especialidade médica que a unidade oferece e não com o local de residência do idoso. Os resultados deste estudo permitem identificar os bairros com maiores concentrações de enfermidades, como doenças cardiovasculares, indicando a necessidade da inserção de outros profissionais nas UBS dos bairros.


This study aimed to describe the demographic and epidemiological characteristics of the elderly population, identify the area of influence of basic care in relation to the area of residence of the elderly and the rate of service use, as well as to map the demand according to the geographic location of the Basic Care Unit. The sample comprised 6,964 male and female subjects aged 60 years or more, who sought any of the outpatient public health services between May 2003 and April 2004. From this total, 64.1 percent were women and 35.9 percent men. The results show that cardiovascular diseases account for the greater part of medical consultations in the health system, with a mean of 3,576 consultations per year per elderly. Geographic mapping showed the demand for medical consultations in determinate basic care units to be related with the medical specialty available at these units. These results allow identifying the neighborhoods with the highest concentrations of specific diseases, indicating the need for insertion/redistribution of professionals between the basic care units in order to improve the quality of life of the elderly.
