ABSTRACT

Los problemas relacionados con los trastornos metabólicos se han incrementado en la actualidad en población joven. Promover un estilo de vida saludable en estudiantes universitarios puede ayudar a prevenir diabetes, enfermedades cardiovasculares y diferentes tipos de cáncer. Objetivo. Calcular el Índice de Masa Corporal (IMC) de universitarios para identificar la prevalencia de obesidad e hipertensión como factores de riesgo metabólico. Materiales y método. Se utilizó muestreo probabilístico aleatorio simple (n= 282, edad 19,1 ± 1,8, 54,6% mujeres, 48,5% hombres). Se realizaron mediciones de peso y estatura para calcular el IMC, circunferencia de cintura y presión arterial. Resultados. Los resultados promedio para mujeres y hombres respectivamente fueron: IMC 24,0 ±5,5 y 25,2 ±5,2 kg/m2 (p= 0,25); cintura 76,25 ± 11,87 y 82,32 ± 15,85 cm (p= 0,001), indicando un riesgo bajo en 73,1% de mujeres y 82,5% de hombres; y presión arterial 127,73/86,03 y 142,3/94,2 mmHg (p= 0,001). La probabilidad de tener hipertensión arterial fue mayor al tener una relación cintura/estatura (RCE) alterada en mujeres y hombres (OR=3,037; IC95% 1,385-6,657 y OR=3,664; IC95% 1,249-2,179, respectivamente). Conclusiones. La población universitaria presenta factores de riesgo que pueden derivar en enfermedades crónicas no transmisibles en un futuro próximo, por lo cual es necesario modificar sus estilos de vida. La RCE es un buen predictor de riesgo de hipertensión en esta población(AU)


The problems related to metabolic disorders have now increased in the young population. Promoting a healthy lifestyle in college students can help prevent diabetes, cardiovascular disease, and different types of cancer. Objective. To calculate the Body Mass Index (BMI) in college students to identify the prevalence of obesity and hypertension as metabolic risk factors. Materials and methods. Simple random probability sampling was used (n = 282, age 19,1 ± 1,8, 54,6% women, 48,5% men). BMI was calculated with weight and height, waist circumference, and blood pressure. Results. The average results for women and men respectively were: BMI 24,0 ± 5,5 and 25,2 ± 5,2 kg/m2 (p = 0,25); waist 76,25 ± 11,87 and 82,32 ± 15,85 cm (p = 0,001), indicating a low risk in 73,1% of women and 82,5% of men; and blood pressure 127,73 / 86,03 and 142,3 / 94,2 mm Hg (p = 0,001). The probability of having arterial hypertension was higher when there was an altered waist / height ratio (WHR) in women and men (OR = 3,037; 95% CI 1,385-6,657 and OR = 3,664; 95% CI 1,249-2,179, respectively). Conclusions. The university population presents risk factors that could lead to chronic diseases. It is necessary to modify their lifestyles to prevent future diseases. WHR is a good predictor of hypertension risk in this population(AU)

ABSTRACT

El objetivo del estudio fue determinar la asociación de valores de presión arterial (PA) con parámetros de adiposidad y nivel de actividad física (NAF) en escolares y adolescentes en la región de la Araucanía en Chile. Materiales y métodos. Estudio descriptivo, transversal y correlacional que consideró una muestra de 1.125 niños, niñas y adolescentes de 6 a 13 años. Se analizaron parámetros de adiposidad: índice de masa corporal, perímetro de cintura y del brazo, pliegue bicipital, tricipital, subescapular y suprailíaco y porcentaje de masa grasa, PA sistólica (PAS), diastólica (PAD) y NAF. Resultados. 60,4% de la muestra esta normotenso; 23,6% pre HTA y 16,0% HTA, sin asociación significativa entre la PA con el sexo (p>0,05). Se encontró para el total de la muestra una correlación significativa entre la PAS con todos los parámetros de adiposidad estudiados (p<0,001; p<0,050). Para la PAD solo el grupo de 6 a 8 años presentó asociación significativa con todos estos parámetros (p<0,001; p<0,050). El NAF se asoció con la clasificación de la PA. Esta asociación tuvo significancia estadística en el grupo de 6 a 8 años (p<0,05). Conclusiones. Se evidencia una elevada frecuencia de PA alta en escolares de una región de Chile. Se identifican asociaciones significativas entre la PA con algunas medidas de adiposidad corporal y el NAF en la muestra de estudio. Esta información puede ser de gran importancia para la predicción de la hipertensión en la infancia en el contexto de atención primaria en salud(AU)


The objective of the study was to determine the association of blood pressure (BP) values with parameters of adiposity and level of physical activity (NAF) in schoolchildren and adolescents in the Araucanía region of Chile. Materials and methods. Descriptive, cross-sectional and correlational study that considered a sample of 1.125 subjects, boys and girls between 6 and 13 years old. Adiposity parameters were analyzed: body mass index, waist and arm circumference, bicipital, tricipital, subscapular and suprailiac fold and% fat mass. Systolic (SBP) and diastolic (DBP) and NAF were also analyzed. Results. 60.4% of the sample is normotensive; 23.6% preHTA and 16.0% HT, without significant association between BP and sex (p> 0.05). For the entire sample, there is a significant correlation between SBP and all the adiposity parameters studied (p <0.001; p <0.050). For DBP, only the 6 to 8-year-old group presented a significant association with all these parameters (p <0.001; p <0.050). The NAF was associated with the PA classification. This association is statistically significant in the 6 to 8-year-old group (p <0.050). Conclusions. A high frequency of high BP is evidenced in schoolchildren from a region of Chile. Significant associations were identified between BP with some measures of body adiposity and NAF in the study sample. This information can be of great importance for the prediction of hypertension in childhood in the context of primary health care(AU)

ABSTRACT

Tradicionalmente se han utilizado algunos índices antropométricos para el diagnóstico de exceso de peso en niños y adolescentes que han mostrado algunas desventajas por lo que se han postulado otros indicadores. En ese sentido, se plantea estimar el nivel de asociación entre indicadores antropométricos y la presencia de dislipidemia en adolescentes y adultos jóvenes. Se realizó una investigación observacional, descriptiva y de corte transversal en 123 adolescentes (68,2% mujeres, edad promedio 14,5 años) y 122 adultos jóvenes (70,5% mujeres, edad promedio 21 años) de la ciudad de Caracas. Se calcularon Índices de Masa Corporal (IMC), Índice Cintura­Talla (ICT), Índice de Masa Corporal Abdominal (IMCA) e Índice de Masa Tri-Ponderal (IMT). Se obtuvo una muestra de sangre por punción venosa, en ayuno de 12 a 14 horas, a partir de la cual se cuantificó Colesterol Total, Lipoproteína de alta densidad y Triglicéridos. Se calculó la concentración de Lipoproteína de baja densidad por la fórmula de Friedewald, así como el índice LDL-C/HDL-C y el índice LogTg/HDL. Para el análisis e interpretación de los datos se utilizó estadística descriptiva univariante y multivariante. Los resultados revelaron que los índices antropométricos IMCA e IMT no mostraron mejor desempeño en predecir dislipidemia que los indicadores IMC, Circunferencia de Cintura (CC) e ICT en adolescentes y adultos jóvenes. Los indicadores antropométricos de adiposidad abdominal, CC e ICT, tendieron a presentar mayores OR, ABC, sensibilidad y especificidad independientemente del grupo de estudio. En general, la capacidad de los indicadores antropométricos evaluados en predecir la presencia de dislipidemia en adultos jóvenes fue adecuada, situación que no se presentó en los adolescentes(AU)


Traditionally, some anthropometric indices have been used for the diagnosis of excess weight in children and adolescents, which have shown some disadvantages for which other indicators have been postulated. In this sense, it is proposed to estimate the level of association between anthropometric indicators and the presence of dyslipidemia in adolescents and young adults. An observational, descriptive cross-sectional investigation was carried out in 123 adolescents (68,2% women, media age 14,5 years) and 122 young adults (70,5% women, media age 21 years) from the city of Caracas. Body Mass Indices (BMI), Waist-Height Ratio (WHR), Abdominal Body Mass Index (BMAI) and Tri-Ponderal Mass Index (TMI) were calculated. A blood sample was obtained by venipuncture, fasting for 12 to 14 hours, from which Total Cholesterol, High Density Lipoprotein and Triglycerides were quantified. The low-density lipoprotein concentration was calculated by the FriedEwald formula, as well as the LDL-C / HDL-C index and the LogTg / HDL index. Univariate and multivariate descriptive statistics were used for the analysis and interpretation of the data. The results revealed that the BMI and TMI anthropometric indices did not show better performance in predicting dyslipidemia than the BMI, Waist Circumference (WC) and WHR indicators in adolescents and young adults. The anthropometric indicators of abdominal adiposity, WC and WHR, tended to present higher OR, AUC, sensitivity and specificity regardless of the study group. In general, the capacity of the anthropometric indicators evaluated to predict the presence of dyslipidemia in young adults was adequate, a situation that did not occur in adolescents(AU)

ABSTRACT

Objetivo: comparar la utilidad del índice cintura-talla y el índice de masa corporal para detectar factores de riesgo cardiometabólicos en niños de 5-18 años, atendidos en la consulta externa del Hospital Infantil Regional Universitario Doctor Arturo Grullón en el período octubre-diciembre del año 2016. Método: se realizó un estudio observacional, comparativo, de corte transversal y fuente primaria, con una muestra de 118 pacientes. Se midieron las variables sociodemográficas (edad y sexo), antropométricas (peso, talla, IMC, ICT, PC, TA), y laboratorios (glicemia, ALT, colesterol, triglicéridos, HDL, LDL). Para el análisis cuantitativo se calculó el promedio y la desviación estándar, para el análisis cualitativo se utilizó la prueba estadística chi-cuadrado. Resultados: tanto el ICT como el IMC detectan de manera similar las alteraciones de la presión arterial sistólica (ICT=15.9 %, IMC=15 %), diastólica (ICT=20.4 %, IMC= 21.8 %), obesidad (ICT=69.5 %, IMC=73.7 %), HDL (ICT=6.8 %, IMC=5.6 %). En relación a la evaluación de la obesidad ambos índices arrojaron resultados afines, 69.5 % para ICT y 73.7 % el IMC. En la valoración de los niveles altos de ALT se obtuvieron resultados similares, presentando el ICT un 8.1 % y el IMC un 8.9 %. Conclusión: se demostró que tanto el ICT como el IMC son buenos predictores de factores de riesgos cardiometabólicos.


Objective: To compare the utility of the WSI and BMI in detecting cardiometabolic risks on children between 5-18 years, during external consult in Hospital Infantil Regional Universitario Dr. Arturo Grullón in the period of October-December 2016. Methods: A cross-sectional, primary source, observational design study was conducted with a sample of 118 patients. The variables measured for this study included sociodemographic (age and sex), anthropometric (weight, height, BMI, ICT, PC), and laboratories (glycemia, ALT, cholesterol, triglycerides, HDL, LDL). The quantitative analysis was carried out by calculating the average and the standard deviation. As for the qualitative analysis, the statistical test χ² was used. Results: Both the WSI and the BMI proved to be effective in detecting changes in Systolic (WSI = 15.9%, BMI = 18.4%) and Diastolic Blood Pressure (WSI = 20.4%, BMI = 18.6%), obesity (WSI = 69.5%, BMI = 73.7%), HDL (WSI = 29.3%, BMI = 29.9%). Regarding the detection of obesity, both rates showed similar results, 69.5% for ICT, and 73.7% for BMI. Comparable results were obtained in the assessment of high levels of ALT, with the ICT at 8.1% and the BMI at 8.9%. Conclusions: WSI and BMI are both useful to detect cardiometabolic risk factors.

ABSTRACT

Abstract INTRODUCTION: Neck circumference (NC) and anthropometric data of people living with HIV (PLWH) are correlated. METHODS: Socioeconomic, NC, body mass index (BMI), tricipital skinfold thickness (TSF), mid-arm circumference (MAC), mid-arm muscle circumference (MAMC), waist-hip ratio (WHR), waist-to-height ratio (WHtR), waist circumference (WC), and hip circumference (HC) data of 72 PLWH were correlated. RESULTS Higher adiposity was observed in NC (40.3% [n=29]) and WC (31.9% [n=23]). Correlations between NC/BMI, NC/WC, NC/HC, NC/MAC, NC/MAMC, and NC/WHtR were significant. Increased NC (40.3%[n=29]) and WC (31.9 [n=23]) were associated with higher cardiometabolic risk. CONCLUSIONS: NC correlations are adequate for estimating cardiometabolic risk.

ABSTRACT

Introducción: El embarazo es una etapa de riesgo de obesidad persistente después del parto, entre otras causas, es secundario al estado nutricional al inicio del embarazo y a las ganancias de peso por encima de lo recomendado. Objetivo: Describir las ganancias de peso gestacionales por categorías nutricionales y su asociación con la retención de peso al año del parto. Métodos: Se realizó un estudio observacional de corte transversal en 100 mujeres al año del parto, pertenecientes a tres áreas de salud del municipio Santa Clara, en el periodo comprendido de julio 2016 a julio 2017. Se revisaron los tarjetones de las embarazadas para recoger el peso en kg a la captación, su evaluación nutricional según el índice de masa corporal en la primera consulta y el peso al final de la gestación. Las mismas fueron visitadas en su domicilio al año de paridas; se recogieron datos generales, se midió la talla de pie, el peso corporal y la circunferencia de la cintura. Se calcularon los índices de masa corporal y cintura/talla. Resultados: Predominó la condición de peso adecuado a la captación (67,08 por ciento). El 82,87 por ciento de las mujeres retuvo peso al año de paridas; con mayor frecuencia en las obesas (90,0 por ciento) y sobrepeso (83,01 por ciento) según su estado nutricional a la captación. Todas las mujeres tuvieron índice cintura/talla por encima de 0,50 al año de paridas. Conclusiones: Las mujeres con mayores ganancias por encima de lo recomendado, tienen menor capacidad de recuperación del peso corporal al año de paridas(AU)


Introduction: Pregnancy is a period of persistent obesity risk after delivery. Among other causes, it is secondary to the nutritional status at the beginning of pregnancy and to gaining weight above the recommended. Objective: To describe gestational weight gains by nutritional categories and their association with weight retention one year after delivery. Methods: An observational and cross-sectional study was conducted with 100 women one year after delivery and from three health areas of Santa Clara Municipality, in the period from July 2016 to July 2017. Their pregnancy identification cards were reviewed to collect their weight in kilograms at the time pregnancy was identified, nutritional evaluation based on the body mass index at the first office visit, and the weight at the end of pregnancy. They were paid home visits one year after delivery. General data were collected, foot size, body weight, and waist circumference were measured. Body mass and waist/height indexes were calculated. Results: The weight condition adequate to the time pregnancy was identified (67.08 percent). 82.87 percent of women retained weight one year after delivery, more frequently in obese (90.0 percent) and overweight (83.01 percent) women according to their nutritional status at the time pregnancy was identified. All women had waist/height index above 0.50 one year after delivery. Conclusions: Women with weight gains higher than recommended have less capacity to recover their body weight one year after delivery(AU)

ABSTRACT

En el mundo la obesidad es considerada una pandemia que provoca grandes cambios metabólicos, responsables de las llamadas enfermedades crónicas no transmisibles (ECNT), las cuales presentan un 60 % de mortalidad, según la Organización Mundial de la Salud (2016). En Chile el 75 % de la población adulta y el 50,9 % de la población estudiantil, muestran índices de masa corporal de sobrepeso y obesidad, con un nivel de sedentarismo general de 66,2 %. Los objetivos de este trabajo fueron determinar los perfiles antropométricos, riesgo metabólico y niveles de actividad física en profesores de enseñanza básica en un colegio particular subvencionado de Arica-Chile. El total de los profesores, 12 varones y 29 mujeres, fueron evaluados según: peso, talla, perímetro de cintura, índice cintura-talla (ICT), índice de masa corporal (IMC), masa grasa (MG), masa grasa visceral (MGV) y masa muscular (MM). A todos ellos se les calculó el riesgo metabólico según protocolos de Ashwell & Gibson (2016) y el IMC según fórmula de Quetelet. Para determinar los porcentajes de MG, MM y MGV, se utilizó instrumento de bioimpedancia eléctrica, Omron HBF-514C. Posteriormente se les aplicó una encuesta sobre nivel de actividad física (IPAQ). Los datos fueron analizados en estadístico IBM SPSS para tendencia central, dispersión, conteos y porcentajes. Para correlación se usó test de Pearson (r>0,5). Los resultados muestran que un 68,3 % de los profesores presenta sobrepeso y obesidad. El IMC y porcentaje de MGV son significativamente más alto en varones que en mujeres (30,6 ±7,0 / 26,9±4,6 y 11,2±5,6 / 7,6±2,5 respectivamente). El riesgo metabólico general de la población en estudio fue de 58,5 % (75 % y 51,7 % varones y mujeres respectivamente). Se observa una alta correlación entre IMC-MGV (0,84), IMC-ICT (0,84) y MM-MG (0,85). Respecto al nivel de actividad física, solo el 19,5 % de los profesores muestra un nivel de actividad física alto. Se concluye que los profesores presentan valores antropométricos alterados que indican altos índices de riesgos metabólicos y con bajos niveles de actividad física. Independientemente, las mujeres presentan mejores índices morfométricos en todos los parámetros en estudio respecto a los profesores varones. Existe una alta correlación (r) entre el índice de masa corporal y los porcentajes de masa de grasa visceral y el índice de de cintura talla. Se sugiere enfocar las intervenciones educativas según sello de vida saludable, incentivando la actividad física y mejorar los hábitos alimenticios en los profesores.


Obesity is considered a global pandemic that causes major metabolic changes. It is responsible for the so-called noncommunicable chronic diseases (NCDs), which report a 60 % mortality rate (WHO, 2017). In Chile, 63 % of the population shows body mass indexes (BMI) of overweight and obesity, with a sedentary level of 86.7 %. The objectives of this work were to determine the anthropometric profiles, metabolic risk, and physical activity levels in primary school teachers, in a subsidized school in Arica, Chile. The teachers (n=41), 12 men, and 29 women were evaluated according to weight, height, waist circumference (WC), waist-to-height index (WHI), BMI, Fat Mass (FM), Visceral Fat Mass (VFM) and Muscle Mass (MM). All of them were calculated for metabolic risk, according to Ashwell & Gibson protocols and BMI according to Quetelet's formula. To determine the percentages of FM, MM, and VFM, an electric bioimpedance instrument, Omron HBF-514C, was used. Subsequently, a survey of physical activity level (IPAQ) was applied. The data were analyzed in the IBM SPSS statistic for central tendency, dispersion, counts, and percentages. For correlation, Pearson's test (r> 0.5) was used. The results show that 68.3 % of teachers are overweight and obese. BMI and percentage of VFM are significantly higher in men than in women (30.6 ± 7.0 / 26.9 ± 4.6 and 11.2 ± 5.6 / 7.6 ± 2.5 respectively). The overall metabolic risk of the study population was 58.5 % (75 % and 51.7 % men and women, respectively). There is a high correlation between BMIVFM (0.84), BMI-WHI (0.84), MM-FM (0.85). Regarding the level of physical activity, only 19.5 % of teachers show a high level of physical activity. It is concluded that teachers have altered anthropometric values that indicate high rates of metabolic risks and low levels of physical activity. Regardless, women have better morphometric indexes in all parameters under study, compared to male teachers. There is a high correlation (r) between body mass index and percentages of visceral fat mass and waist height index. It is suggested to focus on educational interventions according to the healthy life seal, promoting physical activity, and improving eating habits in teachers.

ABSTRACT

ABSTRACT Background: The functional fitness of older people may be associated with their nutritional status. Aim: To assess the association between of anthropometric measures with functional fitness in older people. Material and Methods: Cross-sectional study conducted in 75 participants aged 65 to 89 years. Body mass index (BMI), waist-to-height ratio (WHtR), fat mass (FM) and skeletal muscle mass index (SMI) were calculated from anthropometric measures. The functional fitness was determined using the Senior Fitness Test battery. Results: BMI and FM indicated obesity, and WHtR indicated cardiometabolic risk in 49%, 55% and 83% of participants, respectively. SMI indicated a low muscle mass in 91% of females. Performance standards of chair stand, arm curl, 2-min step test and 8-foot up-and-go tests were met in 1%, 8%, 1% and 89% of participants, respectively. Significant negative correlations were found between 2-min step test and BMI, WHtR and FM (r = −0.26, −0.31 and −0.48 respectively). Back scratch had a negative correlation with BMI (r = −0.23) and SMI (rho = −0.28). Significant positive correlations were found between 8-foot up-and-go, WHtR (rho = 0.28) and FM (rho = 0.23), and between 2-min step test and SMI (rho = 0.28). The coefficient of determination (R2) between 2-min step test with BMI, WHtR and FM were 0.05, 0.08 and 0.22, respectively, while the R2 between back scratch and BMI was 0.04. Multiple regression models indicated that FM affected the 2-min step test independently of BMI and WHtR (adjusted R2 = 0.22), however age and sex negatively influenced these associations. Conclusions: Functional fitness of older adults is influenced by nutritional anthropometric measures, particularly BMI, WHtR and FM for aerobic capacity, and BMI for upper limb flexibility.


Introducción: El estado nutricional y la condición física funcional (CFF) pueden estar relacionados en adultos mayores. Objetivo: Analizar la influencia de medidas antropométricas nutricionales sobre CFF. Material y Método: Estudio transversal realizado en 75 adultos de 65 a 89 años. Las variables antropométricas fueron índice de masa corporal (IMC), razón cintura-talla (RCT), masa adiposa (MA) e índice de masa muscular esquelética (IMME). La evaluación de CFF se efectuó con la batería Senior Fitness Test. Resultados: El IMC y MA indicaron obesidad, y RCT indicó riesgo cardiometabólico en 49%, 55% y 83% de los participantes, respectivamente. IMME indicó una baja masa muscular en 91% de las mujeres. El estándar de rendimiento para las pruebas sentarse-levantarse, flexión-codo, paso-2-minutos y levantarse-caminar-sentarse se logró en 1%, 8%, 1% y 89% de los participantes, respectivamente. Se encontraron correlaciones significativas negativas entre paso-2-minutos con IMC, RCT y MA (r = −0.26,-0.31 y-0.48 respectivamente. La misma asociación se observó entre juntar-manos-espalda con IMC (r = −0.23) e IMME (rho = −0.28). Se encontraron correlaciones significativas positivas entre levantarse-caminar-sentarse con RCT (rho=0.28) y MA (rho = 0.23), y entre paso-2-minutos con IMME (rho = 0.28). Los R2 entre paso-2-minutos e IMC, RCT y MA fueron 0.05, 0.08 y 0.22, respectivamente, mientras que el R2 entre juntar-manos-espalda e IMC fue 0.04. Los modelos de regresión múltiple indicaron que MA afectó la prueba paso-2-minutos independientemente de IMC y RCT (R2 ajustado = 0.22), aunque la edad y sexo afectaron negativamente estas asociaciones. Conclusiones: La CFF de adultos mayores es influenciada por alteraciones evidenciadas por medidas antropométricas nutricionales, particularmente IMC, RCT y MA sobre la capacidad aeróbica, e IMC sobre la flexibilidad de extremidad superior.

ABSTRACT

En este estudio se compara el Índice de Peso-Circunferencia de Cintura (IPCC), con los indicadores Índice de Masa Corporal (IMC), Índice Cintura-Talla (ICT) y Porcentaje de Grasa Corporal (%GC), en tres grupos de sujetos para determinar que tan eficiente resulta en el diagnósticoo de sobrepeso y obesidad y proponerlo como complemento de los otros indicadores mencionados. Métodos: estudio exploratorio, descriptivo, prospectivo y correlacional en una muestra probabilística de 655 sujetos, dividida en tres sub muestras: 455 niños y adolescentes, 97 universitarios y 103 adultos. Variables: edad, sexo, peso, talla, circunferencia de cintura (CC), Índice de Masa Corporal (IMC), Índice Cintura Talla (ICT) e Índice de Peso-Circunferencia de Cintura (IPCC), Porcentaje de Grasa Corporal (%GC). Medidas estadísticas: descriptivas, asociación, correlación, comparación de promedios y regresión logística. Resultados: IMC revela, sobrepeso y obesidad mayor en adultos; CC e ICT mayor riesgo en adultos; %GC reporta obesidad en 6,8% niños, 17,9% universitarios y 64,8% adultos. IPCC se comporta normalmente, aumenta con la edad, 15,6% en niños y adolescentes, 14,4% universitarios y 14,6% adultos, en riesgo. Promedios del IPCC por sexo, en niños y adolescentes, no significativos; correlaciona con peso, talla e IMC (r>0,70). Regresión logística evidencia verosimilitud significativa (p<0,001), regresiones mayores a 0,90 y bondad de ajuste significativas (p<0,000). Conclusiones: Considerar el IPCC conjuntamente con otros indicadores para evaluar sobrepeso y obesidad(AU)


This study compares the Waist Weight-Circumference Index (WIWC), with the indicators Body Mass Index (BMI), Waist-Height Index (WHI) and Body Fat Percentage (BF%), in three groups of subjects to determine how efficient it is in the diagnosis of overweight and obesity and propose it as a complement to the other indicators mentioned. Methods: Methods: exploratory, descriptive, prospective and correlational study in a probabilistic sample of 655 subjects, divided into three sub-samples: 455 children and adolescents, 97 university students and 103 adults. Variables: age, sex, weight, height, waist circumference (WC), Body Mass Index (BMI), Waist Height Index (WHI) and Waist Circumference Weight Index (WIWC), Body Fat Percentage (BF%). Statistical measures: descriptive, association, correlation, comparison of averages and logistic regression. Results: BMI reveals, overweight and obesity in adults; CW and WHI increased risk in adults; BF% reports obesity in 6.8% children, 17.9% university students and 64.8% adults. WIWC behaves normally, increases with age, 15.6% in children and adolescents, 14.4% university students and 14.6% adults, at risk. WIWC averages by sex, in children and adolescents, not significant; correlates with weight, height and BMI (r> 0.70). Logistic regression shows significant likelihood (p <0.001), regressions greater than 0.90 and significant goodness of fit (p <0.000). Conclusions: Consider the WIWC together with other indicators to assess overweight and obesity.

ABSTRACT

El objetivo es comparar dos fórmulas de cálculo del Índice de Masa Corporal (IMC) y relacionarlo con otros indicadores como la Circunferencia de Cintura (CC), Índice Cintura-Talla (ICT), Índice Peso Circunferencia de Cintura (IPCC) y etnia. MÉTODOS: Estudio descriptivo, transversal, prospectivo y correlacional. Una muestra de 480 niños y adolescentes, de 6 a 15 años, de dos instituciones educativas de Caracas, Municipio Libertador, seleccionados al azar de los grados y secciones previamente elegidas, se solicitó consentimiento informado a sus representantes. Variables: etnia, sexo, peso, talla, IMC, CC, ICT, % GC e IPCC. Se determinó promedio, desviación, porcentajes, comparación de medias y porcentajes y correlaciones. RESULTADOS: Promedios del IMC-Oxford ligeramente mayores a los del IMC-Quetelet, por edad. Al clasificar según Normopeso, Sobrepeso y Obesidad, promedios de los dos IMC son significativos; promedios de todas las variables, no significativos por sexo, excepto para el % GC (p<0,000), este aumenta considerablemente con la edad. La clasificación de la CC 15,0 % Riesgo sobrepeso y 5,0 % Obesidad; el % GC clasifica 19,5 % en Exceso, mayor en el sexo femenino, hay un alto porcentaje en Déficit (65,8 %). Correlaciona IMC-Q con IPCC (r=0,84), IMC-O con IPCC (r=0,70) e IMC-Q con IMC-O (r= 0,97). Los indicadores CC, ICT e IPCC, se comportan similarmente en los tres grupos de clasificación de los IMC; y en las tres etnias según los percentiles, y los valores de la CC siempre mayores a los del IPCC. CONCLUSIÓN: el IMC-Oxford puede ser utilizado como una nueva opción para evaluar Sobrepeso y Obesidad, en grupos de niños y adolescentes.


The objective is to compare two Body Mass Index (BMI) calculation formulas and relate it to other indicators such as Waist Circumference (CC), Waist-Size Index (ICT), Weight-Waist Circumference Index (IPCC), and ethnicity. METHODS: Descriptive, cross-cutting, prospective and correlative study. A sample of 480 children and adolescents, aged 6 to 15, from two educational institutions in Caracas, Libertador Municipality, randomly selected from the degrees and sections previously chosen, requested informed consent from their representatives. Variables: ethnicity, gender, weight, size, BMI, WC, ICT, BFP and WWCI. Average, deviation, percentages, comparison of means and percentages and correlations were determined. RESULTS: BMI-Oxford averages slightly higher than BMI-Quetelet, by age. When classifying by Normoweight, Overweight and Obesity, averages of the two BMI are significant; averages of all variables, not significant by sex, except for % GC (p<0.000), this increases considerably with age. CC rating 15.0 % Overweight risk and 5.0 % Obesity; % GC ranks 19.5 % in Excess, higher in the female sex, there is a high percentage in Deficit (65,8 %). It maps IMC-Q to WWCI (r-0.84), IMC-O with WWCI (r-0.70), and IMC-Q with IMC-O (r-0.97). The CC, WTS and WWCI indicators behave similarly in the three BMI classification groups; and in the three ethnicities according to the percentiles, and the VALUES of the WC always higher than those of the WWCI. CONCLUSION: BMI-Oxford can be used as a new option to evaluate Overweight and Obesity, in groups of children and adolescents .

ABSTRACT

Abstract Objective: Given the importance of incorporating simple and low-cost tools into the pediatric clinical setting to provide screening for insulin resistance, the present study sought to investigate whether waist-to-height ratio is comparable to biochemical markers for the discrimination of insulin resistance in children and adolescents. Methods: This cross-sectional study involved students from nine public schools. In total, 296 children and adolescents of both sexes, aged 8 -14 years, composed the sample. Waist-to-height ratio, triglycerides/glucose index, and triglycerides-to-HDL-C ratio were determined according to standard protocols. Insulin resistance was defined as homeostatic model assessment for insulin resistance with cut-off point ≥ 3.16. Results: Age, body mass index, frequency of overweight, waist circumference, waist-to-height ratio, insulin, glucose, homeostatic model assessment for insulin resistance, triglycerides, triglycerides/glucose index, and triglycerides-to-HDL-C were higher among insulin resistant boys and girls. Moderate correlation of all indicators (waist-to-height ratio, triglycerides/glucose index, and triglycerides-to-HDL-C ratio) with homeostatic model assessment for insulin resistance was observed for both sexes. The areas under the receiver operational characteristic curves ware similar between waist-to-height ratio and biochemical markers. Conclusion: The indicators provided similar discriminatory power for insulin resistance. However, taking into account the cost-benefit ratio, we suggest that waist-to-height ratio may be a useful tool to provide screening for insulin resistance in pediatric populations.


Resumo Objetivo: Considerando a importância de incorporar ferramentas simples e de baixo custo no cenário clínico-pediátrico para a triagem de resistência à insulina, o presente estudo buscou investigar se a razão cintura/estatura é comparável a marcadores bioquímicos na discriminação de resistência à insulina em crianças e adolescentes. Métodos: Este estudo transversal envolveu estudantes de nove escolas públicas. No total, 296 crianças e adolescentes, de ambos os sexos, com idades entre 8 e 14 anos, compuseram a amostra. A razão cintura/estatura, o índice triglicerídeos/glicose e a razão triglicerídeos/HDL-C foram determinados de acordo com protocolos padrão. A resistência à insulina foi definida por meio do modelo de avaliação homeostática para resistência insulínica, com ponto de corte ≥ 3.16. Resultados: Idade, índice de massa corporal, frequência de excesso de peso, circunferência da cintura, razão cintura/estatura, insulina, glicemia, modelo de avaliação homeostática para resistência insulínica, triglicerídeos, índice triglicerídeos/glicose e razão triglicerídeos/HDL-C foram maiores entre meninos e meninas com resistência à insulina. Também foram observadas, em ambos os sexos, correlações moderadas de todos os indicadores (razão cintura/estatura, índice triglicerídeos/glicose e razão triglicerídeos/HDL-C) com o modelo de avaliação homeostática para resistência à insulina. As áreas sob as curvas ROC foram semelhantes entre a razão cintura/estatura e os marcadores bioquímicos. Conclusão: Os indicadores forneceram poder discriminatório similar para a resistência à insulina. No entanto, levando em conta o custo-benefício, sugerimos que a razão cintura/estatura pode ser uma ferramenta útil para a triagem de resistência à insulina em populações pediátricas.

ABSTRACT

Resumo O objetivo deste artigo é investigar a associação entre demência e indicadores antropométricos em idosos de Florianópolis. Estudo transversal, de base populacional, realizado com 1.197 idosos (≥ 60 anos) em 2013/2014. A demência foi considerada como a presença conjunta de escore baixo no Miniexame do Estado Mental (MEEM) e a incapacidade funcional moderada/grave nas atividades de vida diária (AVD). As variáveis independentes avaliadas foram: índice de massa corporal (IMC), perímetro da cintura (PC), índice de conicidade e relação cintura/estatura (RCEst). A regressão logística (bruta e ajustada) foi utilizada para identificar os fatores associados. A prevalência estimada de demência foi de 15,1%. Após ajustes para características sociodemográficas, estilo de vida e sintomas depressivos, a demência foi positivamente associada aos tercis superiores do IMC (OR: 2,32; IC95%: 1,26-4,25), PC (OR: 2,22; IC95%: 1,20-4,11) e RCEst. (OR: 2,30; IC95%: 1,19-4,43). De acordo com os resultados, tanto a obesidade quanto a gordura abdominal foram associados ao desfecho, sugerindo que o IMC, o PC e a RCEst. devam ser considerados na investigação dessa relação.


Abstract Objective To investigate the association between dementia and anthropometric indicators in the elderly from Florianópolis. Method This is a cross-sectional population-based survey performed with 1,197 elderly (≥ 60 years) in 2013/2014. Dementia was defined as the combined evidence of low MMSE (Mini-Mental State Examination) score and moderate/severe disability in the activities of daily living. The independent variables were body mass index (BMI), waist circumference (WC), conicity index and waist-to-height ratio (WHtR). Logistic regression (crude and adjusted) was performed to identify associated factors. Results Dementia prevalence was estimated at 15.1%. After adjustment for sociodemographic characteristics, lifestyle and depressive symptoms, dementia was positively associated with the upper tertiles of the BMI (OR: 2.32; CI95%: 1.26-4.25), WC (OR: 2.22; CI95%: 1.20-4.11) and WHtR (OR: 2.30; CI95%: 1.19-4.43). Conclusion Results have shown that both obesity and abdominal fat were associated with the outcome, suggesting that BMI, WC and WHtR should be considered in the investigation of this relationship.

ABSTRACT

Resumo O objetivo deste estudo foi determinar e comparar a magnitude da associação entre indicadores antropométricos com fatores de risco cardiometabólico em idosos. Trata-se de estudo transversal com 402 idosos atendidos pela Estratégia Saúde da Família no município de Viçosa-MG. Os fatores de risco considerados foram o excesso de gordura corporal, hipertensão arterial, alteração da glicemia e dos lipídeos séricos. A associação entre o índice de conicidade (IC) e a relação cintura/estatura (RCE) com os fatores de risco cardiometabólico foi avaliada pela análise de regressão linear múltipla. A amostra foi composta por 60,4% de mulheres e 36,3% de idosos com excesso de peso. O índice de conicidade e a relação cintura/estatura estiveram elevados em 57,2% e 88,1% dos idosos, respectivamente. Os resultados demonstraram que o aumento da gordura corporal, da pressão arterial diastólica, dos triglicerídeos, da glicemia e a redução do HDL-colesterol estão relacionados a maiores valores dos índices antropométricos avaliados. No entanto, a relação cintura/estatura apresentou maior magnitude de associação com os fatores de risco cardiometabólico do que o índice de conicidade.


Abstract The purpose of this study was to determine and compare a magnitude of the association between anthropometric indicators with risk of cardiometabolic risk in the elderly. This is a cross-sectional study with 402 elderly people attended by the Family Health Strategy in the city of Viçosa-MG. Risk factors for excess body fat, hypertension, blood glucose and serum lipid changes. An association between conicity index (CI) and waist-to-height ratio (WtHR) with cardiometabolic risk factors was assessed by multiple linear regression analysis. Sample was composed of 60.4% of women and 36.3% of overweight elderly. The connectivity index and a waist-to-height ratio were higher in 57.2% and 88.1% in the elderly, respectively. The results showed that the increase in body fat, diastolic blood pressure, triglycerides, glycemia and reduction of HDL-cholesterol are related to higher values of anthropometric indices evaluated. However, the waist-to-height ratio presented a greater magnitude of association with the cardiometabolic risk factors than the connectivity index.

ABSTRACT

ABSTRACT OBJECTIVE To evaluate the performance of the ratio between the waist circumference and the height in the identification of health risk compared with the correlation matrix between the anthropometric parameters body mass index and waist circumference. METHODS A population-based study presenting a transversal cut in a representative sample of the Brazilian adult and older population. The combination of the body mass index with the waist circumference resulted in health risk categories, and the cutoff points of the ratio between the waist circumference and the height as anthropometric indicator were used for classification of low and increased risk. Poisson regression was used to verify the association of systemic arterial hypertension with the health risk categories. RESULTS The results showed 26% of adult men, 10.4% of adult women and more than 30% of the older adults of both genders classified as without risk by the combination matrix between body mass index and waist circumference presented a ratio between the waist circumference and height that showed increased risk. All risk categories continued to be associated with hypertension after control for confounding factors, being almost two times higher for adults with moderate and high risk according to both methods. When the waist-to-height ratio was used as a risk indicator, the prevalence of hypertension ratios for the older adults was 1.37 (95%CI 1.16-1.63) and 1.35 (95%CI 1.12-1.62) for men and women, respectively, being these values close to the combination matrix body mass index and waist circumference. CONCLUSIONS The waist-to-height ratio identified more individuals at early health risk than the combination matrix between the body mass index and the waist circumference and showed comparable ability to identify health risk, regardless of gender and age, regarding the prevalence ratios for systemic arterial hypertension.


RESUMO OBJETIVO Avaliar o desempenho da razão entre a circunferência da cintura e a estatura na identificação de risco à saúde comparada à matriz de associação entre os parâmetros antropométricos índice de massa corporal e circunferência da cintura. MÉTODOS Estudo de base populacional apresentando um corte transversal em uma amostra representativa da população adulta e idosa brasileira. A combinação do índice de massa corporal com a circunferência da cintura deu origem às categorias de risco à saúde, assim como os pontos de corte da razão entre a circunferência da cintura e a estatura como indicador antropométrico foram utilizados para a classificação de baixo risco e risco aumentado. A regressão de Poisson foi utilizada para verificar a associação da hipertensão arterial sistêmica com as categorias de risco à saúde. RESULTADOS Os resultados apontaram que 26% dos homens adultos, 10,4% das mulheres adultas e mais de 30% dos idosos de ambos os sexos classificados como sem risco pela matriz de combinação índice de massa corporal e circunferência da cintura apresentaram razão entre a circunferência da cintura e a estatura indicativa de risco aumentado. Todas as categorias de risco continuaram apresentando associação com a hipertensão após controle para os fatores de confusão, permanecendo próximas de duas vezes maiores para os indivíduos adultos com risco moderado e elevado segundo ambos os métodos. Já os idosos apresentaram razões de prevalência de hipertensão de 1,37 (IC95% 1,16-1,63) e de 1,35 (IC95% 1,12-1,62), para homens e mulheres, respectivamente, quando utilizada a razão entre a circunferência da cintura e a estatura como indicador de risco, estando estes valores próximos à matriz de combinação índice de massa corporal e circunferência da cintura. CONCLUSÕES A razão entre a circunferência da cintura e a estatura identificou mais indivíduos em risco precoce à saúde do que a matriz de combinação entre o índice de massa corporal e a circunferência da cintura e apresentou habilidades comparáveis na identificação de risco à saúde, independentemente do sexo e da faixa etária, no que tange às razões de prevalência para hipertensão arterial sistêmica.

ABSTRACT

RESUMO: Objetivo: Determinar o poder preditivo do índice de massa corporal (IMC), perímetro da cintura (PC) e razão da cintura pela estatura (RCEst) e de seus respectivos pontos de corte para triagem de pressão arterial (PA) elevada em crianças e adolescentes brasileiros. Método: Estudo transversal realizado com1.139 escolares de 6 a 17 anos de idade. A massa corporal, a estatura, o PC e a PA foram mensurados. A PA elevada foi classificada como sistólica ou diastólica≥ percentil 95. Curvas Receiver Operating Characteristic (ROC) foram construídas e a área sob a curva, a sensibilidade e a especificidade foram calculadas. Resultados: A prevalência de PA elevada foi de 27,0%. Os indicadores antropométricos apresentaram associação significativa com PA elevada (acurácia variando de 0,62 - 0,81), exceto RCEst entre adolescentes do sexo masculino.Observou-se baixa sensibilidade, independentemente do indicador antropométrico, do sexo e da faixa etária. Conclusão: OIMC, o PC e a RCEst estiveram associados a PA elevada, porém os pontos de corte testados apresentaram baixa sensibilidade. A determinação de pontos de corte específicos para cada população pode viabilizar a triagem de PA elevada por meio de indicadores antropométricos.


ABSTRACT: Objective: To determine the predictive power of body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR), and their respective cut-off points for high blood pressure (BP) screening in Brazilian children and adolescents. Method: Cross-sectional study conducted with 1,139 students aged 6 to 17years. Body weight, height, WC, and BP were measured. High BP was classified as systolic or diastolic ≥ 95th percentile. Receiver Operating Characteristic (ROC) curves were constructed, and the area under the curve, sensitivity, and specificity were calculated. Results: The prevalence of high BP was 27.0%. Anthropometric indices showed a significant association with high BP (accuracy ranging from 0.62 - 0.81), except for WHtR among male adolescents.Sensitivity was low, regardless of the anthropometric index, gender, and age group. Conclusion: BMI, WC, and WHtR were associated with high BP, but the cut-off points tested showed low sensitivity. Determining specific cut-off points for each population can enable the use of anthropometric indices in high BP screening.

ABSTRACT

El sobrepeso y la obesidad, representan una preocupación para las autoridades de salud, dado que se ha incrementado en los últimos años; particularmente en poblaciones adultas. Objetivo: Relacionar el porcentaje de grasa corporal con la circunferencia de cintura, el índice cintura/talla y el Índice de Masa Corporal, como indicadores de obesidad en sujetos con diagnóstico de hígado graso no alcohólico. Materiales y Métodos: estudio descriptivo, transversal en una muestra de 137 adultos, de 18 a 70 años. Se midieron las variables: Edad, Talla, Peso, Circunferencia de Cintura (CC), Índice de Masa Corporal (IMC), Índice Cintura/Talla (ICT), Índice peso/circunferencia de cintura (IPCC), Porcentaje de Grasa Corporal (%GC). Se determinaron promedios, desviación, correlaciones y prueba t de student. Resultados: Promedio: edad (47,06±13,71 años), peso (77,94±21,99 kg), talla (160,57±9,20 cm), IMC (30,21±7,92 kg/m2), CC (0,96±0,16 cm), ICT (0,60±0,10), IPCC (0,80±0,11), %GC (34,19±10,88). Según IMC, 34,3% sobrepeso y 39,4% obesos. Según CC, Riesgo elevado 19,0% y Riesgo muy elevado 55,5%. Según ICT, sobrepeso 10,9%, sobrepeso elevado 21,2% y obesidad 51,8%. Según IPCC, 54,0% en riesgo. Según %GC, 13,9% en límite y 52,5% obesidad. Alta correlación entre %GC e IMC (r = 0,85) y entre GC% y CC (r = 0,89). Conclusiones: el IMC es un buen indicador de obesidad, pero es importante conocer la cantidad de grasa del organismo. Se sugiere el %GC como complemento para diagnosticar obesidad; además al agregar CC, como indicador de grasa abdominal, se puede hacer un diagnóstico más preciso de la obesidad para garantizar un adecuado tratamiento y mejorar la calidad de vida en el adulto.

Overweight and obesity represent a concern for health authorities, given that it has increased in recent years. Objective: Relate the percentage of body fat with waist circumference, the index size waist and body mass (BMI), as an indicator of obesity. Materials and methods: descriptive, cross-sectional study in a sample of 137 adults, 18 to 70 years. Measured variables: age, height, weight, waist circumference (WC), body mass (BMI), waist height index (WHtR), index weight waist circumference (WWCtR), percentage of body fat (BFP). Determined average, deviation, correlation and test student's t. Results: Average: age (47, 06±13,71 years), weight (77,94±21,99 kg), height (160,57±9,20 cm), BMI (30,21 ± 7,92 kg/m2), WC (0,96±0,16 cm), WHCtR (0,60±0,10), WWCtR (0,80±0,11), BFP(34,19±10,88). According to the BMI, 34.3% obese and 39, 4% overweight. According to WC, high-risk 19.0% and 55.5% very high risk. According to WWCtR, 10, 9% overweight, elevated 21, 2% overweight and obesity 51, 8%. According to WWCtR, 54, 0% at risk. According to BFP, 13, 9% in limit and 52, 5% obesity. High correlation between BMI and BFP (r=0, 85) and between the BFP and WC (r=0, 89). Conclusions: BMI is a good indicator of obesity, but it is important to know the amount of fat in the body. It is suggested the BFP as a complement to diagnose obesity; in addition to add WC, as an indicator of abdominal fat, a more accurate diagnosis of obesity can be to ensure adequate treatment and improve the quality of life in the adult(AU)

ABSTRACT

The aim was to evaluate the separate and joint association of abdominal adiposity indicators (a body shape index - ABSI, waist circumference - WC, waist-to-height ratio - WHtR) and body mass index (BMI) with arterial hypertension and diabetes mellitus, in Brazilian older adults. Data from the 2013 Brazilian National Health Survey (PNS 2013) were used for the population aged 60 years or older (10,537 older adults). Arterial hypertension and diabetes mellitus outcomes were self-reported and the following anthropometric indices were evaluated by direct measurement: a ABSI, BMI, WC and WHtR. Associations were assessed by logistic regression, with adjustments for confounding factors. The results of this study evidenced a higher strength of association between the report of arterial hypertension and diabetes mellitus with BMI, WC and WHtR in the Brazilian population of older adults in separate analyses, when compared to ABSI. When adjusted for BMI, ABSI showed a greater strength of association with the outcomes, but it was not superior to the performance of WC and WHtR. Considering the lower strength of association, in separate and joint analyses, between the new index (ABSI) and the chronic conditions assessed, BMI, WC and WHtR probably remain as useful indices in public health, at least in relation to arterial hypertension and diabetes mellitus in Brazilian older adults.


O estudo teve como objetivo avaliar a associação isolada e conjunta dos indicadores de adiposidade abdominal (a body shape index - ABSI, circunferência da cintura - CC, razão cintura-estatura - RCE) e índice de massa corporal (IMC) com a hipertensão arterial e o diabetes mellitus em idosos brasileiros. Foram usados dados da Pesquisa Nacional de Saúde (PNS 2013) para a população com 60 anos ou mais (10.537 idosos). A hipertensão arterial e o diabetes mellitus foram auto-relatados, e os seguintes índices antropométricos foram avaliados através da aferição direta: índice de formato corporal ABSI, IMC, CC e RCE. As associações foram avaliadas por regressão logística, com ajustes para fatores de confusão. Os resultados do estudo evidenciaram uma associação mais forte entre o relato de hipertensão arterial e diabetes mellitus em análises separadas com IMC, CC e RCE na população idosa brasileira, quando comparado ao ABSI. Quando ajustado para IMC, o ABSI mostrou uma associação mais forte com os desfechos, mas não foi superior ao desempenho da CC ou da RCE. Considerando a associação mais fraca nas análises separadas e conjuntas entre o novo índice (ABSI) e as doenças crônicas avaliadas, o IMC, CC e RCE ainda são índices úteis na saúde pública, pelo menos em relação à hipertensão arterial e ao diabetes mellitus em idosos brasileiros.


El objetivo de este estudio fue evaluar la asociación independiente y conjunta de los indicadores de adiposidad abdominal (a body shape index - ABSI, circunferencia de cintura - CC, proporción cintura-altura - ICA) y el índice de masa corporal (IMC) con la hipertensión arterial y la diabetes mellitus, en ancianos brasileños. Los datos procedieron de la Encuesta Nacional de Salud de 2013 (PNS 2013) pertenecientes a una población con 60 años o más (10.537 ancianos). Los resultados de hipertensión arterial y diabetes mellitus fueron autoinformados y se evaluaron los siguientes índices antropométricos mediante medición directa: ABSI, IMC, CC y ICA. Las asociaciones se evaluaron mediante regresión logística, con ajustes por factores de confusión. Los resultados del presente estudio evidenciaron una fuerza de asociación más alta entre el reporte de hipertensión arterial y la diabetes mellitus con el IMC, CC e ICA en la población anciana brasileña en los análisis por separado, cuando se compararon con el ABSI. Cuando se ajustó al IMC, el ABSI mostró una fortaleza mayor de asociación con los resultados, pero no fue superior al desempeño de la CC e ICA. Considerando una fortaleza de asociación más baja, en los análisis por separado y conjuntos, entre el nuevo índice (ABSI) y las condiciones crónicas de salud evaluadas, IMC, CC e ICA probablemente siguen siendo índices útiles en salud pública, al menos en relación con la hipertensión arterial y la diabetes mellitus en ancianos brasileños.

ABSTRACT

PURPOSE: This study aimed to evaluate the time trends of waist circumference (WC) and waist-height ratio (WHR), and to present WC and WHR distributions with optimal WHR cutoff for abdominal obesity in Korean children and adolescents. METHODS: We performed a retrospective cross-sectional analysis of data from 13,257 children and adolescents (6,987 boys and 6,270 girls) aged 6–18 years who were included in the third to sixth Korea National Health and Nutrition Examination Survey (KNHANES, 2005–2015). Linear regression analyses were used to identify secular changes in WC and WHR by age, sex, and KNHANES waves. A receiver operating characteristic curve analysis was used to determine the optimal WHR cutoff values for abdominal obesity and cardiometabolic risk factors. RESULTS: The mean WC and WHR distributions from 2005 to 2015 showed no significant secular changes between the KNHANES 4 waves (P for trend ≥0.05 in all ages and both sexes). The mean WCs in the present study were lower than those in the 2007 Korean National Growth Charts. The mean WHR at ages <13 years was statistically higher in the boys than in the girls, but did not significantly differ between the sexes among those aged 13 to 18 years. The optimal WHR cutoff for abdominal obesity was 0.48 (area under the curve, 0.985; 95% confidence interval, 0.985–0.985) in the 13- to 18-year-old adolescents. CONCLUSION: WC and WHR showed no secular changes over 10 years. The optimal WHR cutoff for abdominal obesity of 0.48 is useful for diagnosing and managing obesity and thus preventing obesity-related cardiometabolic complications in 13- to 18-year-old Korean adolescents.
