ABSTRACT

Las medidas antropométricas resultan de utilidad para evaluar el estado nutricional, son fáciles de obtener cuando se aplican a poblaciones de ancianos ambulantes. Objetivo: evaluar antropométricamente un grupo de adultos mayores; para ello se midieron las variables: edad, peso, talla, Circunferencia de cintura (CC), perímetro de pantorrilla (PP) y se calcularon IMC, ICT, IPCC y %GC. Métodos: Se seleccionó un grupo de adultos mayores, quienes asistieron a la consulta en una clinica privada, del área metropolitana de Caracas, durante los mese de junio y octubre de 2015. Se determinaron los indicadores IMC, CC, PP, ICT, IPCC y %GC, para clasificar, según las categorías de cada uno, a los adultos, y evaluar su estado nutricional. Resultados: Los resultados indican edad 71,9±7,9 años, peso 67,1±13,9, talla 157,6±9,2 cm, CC 93,7±12,2, PP 33,7±4,1, IMC 26,9±4,7, ICT 0,60±0,08, IPCC 0,71±0,10 y %GC 40,4±7,7. Desnutrición según el PP 42,3%(M) y 15,6%(F); Sobrepeso según IMC 69,1%(M) y 62,9% (F); obesidad 30,8% (M) y 37.1%(F). Riesgo elevado y riesgo muy elevado, según la CC, 42,1% (M) y 20,6% (F), y 58,9% (M) y 77,4% (F), respectivamente. ICT revela obesidad 20,7% (M) y 62,2% (F); IPCC riesgo 78,2% (M) y 49,6% (F); %GC obesida 95,5% (M) y 98,3% (F). Correlaciones altas entre CC-ICT, Peso-IMC, Peso-CC, Peso-IPCC (r ≥ 0,80 y p<0,001). Conclusión: los indicadores son muy útiles para evaluar el estado nutricional, y disponer de varios de ellos, permite complementar la evaluación nutricional en el adulto mayor(AU)

ABSTRACT

O objetivo do estudo é analisar os efeitos de um programa de intervenção interdisciplinar no perfil de risco cardiometabólico de adolescentes com diagnóstico de sobrepeso/ obesidade. Estudo de intervenção, realizado com adolescentes com excesso de peso, constituído por grupo controle e grupo intervenção, o qual participou de um programa interdisciplinar com duração de seis meses. O grupo experimental final é composto por 23 adolescentes (12 sexo feminino e 11 sexo masculino). No início do programa, quatro adolescentes apresentavam sobrepeso e 19 obesidade. O grupo controle é composto pelo mesmo número de sujeitos, uma vez que este foi composto pelos pares dos escolares do grupo experimental. A intervenção contou com sessões de exercícios físicos, em três dias da semana e orientações nutricionais e psicológicas, uma vez por semana. Uma avaliação foi realizada antes do inicio do programa e logo após seu término. As avaliações consistiram em variáveis antropométricas - índice de massa corporal, circunferência da cintura, razão cintura-estatura e razão cintura -quadril, avaliação da pressão arterial, da aptidão cardiorrespiratória e coleta sanguínea para avaliação do perfil lipídico. Para a comparação das variáveis no período pré e pós-intervenção foi utilizado o teste t para amostras pareadas, para as variáveis de distribuição normal e, para as variáveis não paramétricas, foi aplicado o t este de Wilcoxon, considerando o nível de significância de p<0,05. O programa de intervenção foi eficaz n a redução de todos os indicadores antropométricos, na melhora dos níveis de aptidão cardiorrespiratória e na redução dos níveis de colesterol LDL. Entretanto, não modificou de forma significativa o s níveis de pressão arterial e demais parâmetros do perfil lipídico (colesterol total, HDL e triglicerídeos)...(AU)

Intervention study with overweight adolescents, consisting of a control group and an intervention group, which participated in an interdisciplinary program lasting six months. The final experimental group co nsists o f 23 adolescents (12 females and 11 males). At the beginning of the program, four adolescents were overweight and 19 were obese. The control group is composed of the number of subject s, sin ce it was composed by the pairs of students in the experimental group. The intervention coun ted o n sessio n s o f physical exercises, in three days of the week and nutritional and psychological orientations, once a week . An evaluation was carried out before the start of the program and soon after its completion. The evaluations consisted of anthropometric variable - body mass index, waist circumference, waist-to-waist ratio, and waist-to-hip ratio, arterial pressure, cardiorespiratory fitness evaluation and blood collection t o evaluate the lipid profile. For the comparison of the variables in the pre- and post-intervention period, t he t-test for paired samples was used for the variables of normal distribution and fo r th e n on-parametric variables the Wilcoxon test was used, considering the level of significance of p < 0.05. The intervention program was effective in reducing all anthropometric indicators, improving cardiorespiratory fitness levels and reducing LDL cholesterol levels. However, it did not significantly modify the blood pressure levels and other parameters of the lipid profile (total cholesterol, HDL and triglycerides)...(AU)

ABSTRACT

This study was conducted to analyze the biochemical index, nutrient intakes, nutrition label use, diet-related factors and weight control behavior of Korean female adolescents at the age of 12 to 18 according to body mass index (BMI) by using the results of the 2010 and 2011 Korea National Health and Nutrition Examination Surveys. The obese group had higher waist circumference (p < 0.001) and systolic blood pressure (p < 0.01) than the normal group. In the biochemical index, the obese group had lower serum high-density lipoprotein-cholesterol level (p < 0.001), while their triglyceride level was higher than the normal group (p < 0.01). Nutrient intake according to BMI was not significantly different except carbohydrate, and calcium intake was about 53% of recommended nutrient intake in all study subjects. The nutrition label was recognized in more than 90% of all groups. But actual nutrition label use was below 50% in all groups and the underweight group was the lowest (p < 0.05). In the result for subjective body image perception, even in the group with normal BMI, 25.3% recognized themselves as obese, and 75.3% said they were trying to lose weight, indicating that many female teens actually think their bodies are obese. In conclusion, obese female adolescents have high systolic blood pressure and serum triglyceride concentrations, which requires obesity prevention education. And a large number of female adolescents with normal BMI thought they were obese and tried to lose weight. Therefore, education on healthy weight and calcium intake is necessary.

ABSTRACT

PURPOSE: Obese children may often present with advanced bone age. We aimed to evaluate the correlation between factors associated with childhood obesity and advanced bone age.METHODS: We enrolled 232 overweight or obese children. Anthropometric and laboratory data, and the degree of nonalcoholic fatty liver disease (NAFLD) were measured. We analyzed factors associated with advanced bone age by measuring the differences between bone and chronological ages.RESULTS: The normal and advanced bone age groups were comprised of 183 (78.9%) and 49 (21.1%) children, respectively. The prevalence of advanced bone age significantly increased as the percentiles of height, weight, waist circumference, and body mass index (BMI) increased. BMI z-score was higher in the advanced bone age group than in the normal bone age group (2.43±0.52 vs. 2.10±0.46; p < 0.001). The levels of insulin (27.80±26.13 μU/mL vs. 18.65±12.33 μU/mL; p=0.034) and homeostatic model assessment–insulin resistance (6.56±6.18 vs. 4.43±2.93; p=0.037) were significantly higher, while high density lipoprotein-cholesterol levels were lower (43.88±9.98 mg/dL vs. 48.95±10.50 mg/dL; p=0.005) in the advanced bone age group compared to those in the normal bone age group, respectively. The prevalence of advanced bone age was higher in obese children with metabolic syndrome than in those without (28.2% vs. 14.7%; p=0.016). The prevalence of advanced bone age was higher in obese children with a more severe degree of NAFLD.CONCLUSION: Advanced bone age is associated with a severe degree of obesity and its complications.

ABSTRACT

PURPOSE: To describe the 4-year metabolic follow-up results from the BLAST study.MATERIALS AND METHODS: Baseline hemoglobin A1c (HbA1c), weight, and waist circumference (WC) data were recorded in 185 men recruited for the BLAST randomised controlled trial (RCT) and erectile function (EF) scores were also available in an additional 48 men screened for the RCT. Intra/inter-group associations between these parameters and testosterone replacement therapy (TRT) were assessed at 1) end of the RCT (30 weeks), 2) open-label phase (82 weeks), and 3) final assessment via non-parametric statistics.RESULTS: Improvement in HbA1c and weight at the end of the RCT and open-label phase in men on TRT was not maintained long-term. The convergence in HbA1c could have been due to incentivised care with HbA1c targets. Interestingly those on TRT at final assessment required fewer anti-diabetic agents. The weight increase in routine care may have been due to changes in diabetes medication or an increase in lean muscle mass. WC continued to decrease in men on TRT indicating possible reduction in visceral fat. Improvement in EF scores continued with long-term TRT, this was abolished when TRT was discontinued.CONCLUSIONS: This study hints at benefits in glycaemic control, weight and WC, and long-term RCTs studying mechanisms of benefit and clinical outcomes are necessary. Our results also show that EF scores continued to improve with long-term TRT, even beyond the 6 months that we previously reported in the BLAST RCT.

ABSTRACT

BACKGROUND: Membrane CD36 is a fatty acid transporter implicated in the pathogenesis of metabolic disease. We aimed to evaluate the association between plasma CD36 levels and diabetes risk and to examine if the association was independent of adiposity among Danish population.METHODS: We conducted a case-cohort study nested within the Danish Diet, Cancer and Health study among participants free of cardiovascular disease, diabetes and cancer and with blood samples and anthropometric measurements (height, weight, waist circumference, and body fat percentage) at baseline (1993 to 1997). CD36 levels were measured in 647 incident diabetes cases that occurred before December 2011 and a total of 3,515 case-cohort participants (236 cases overlap).RESULTS: Higher plasma CD36 levels were associated with higher diabetes risk after adjusting for age, sex and other lifestyle factors. The hazard ratio (HR) comparing high versus low tertile of plasma CD36 levels was 1.36 (95% confidence interval [CI], 1.00 to 1.86). However, the association lost its significance after further adjustment for different adiposity indices such as body mass index (HR, 1.23; 95% CI, 0.87 to 1.73), waist circumference (HR, 1.21; 95% CI, 0.88 to 1.68) or body fat percentage (HR, 1.20; 95% CI, 0.86 to 1.66). Moreover, raised plasma CD36 levels were moderately associated with diabetes risk among lean participants, but the association was not present among overweight/obese individuals.CONCLUSION: Higher plasma CD36 levels were associated with higher diabetes risk, but the association was not independent of adiposity. In this Danish population, the association of CD36 with diabetes risk could be either mediated or confounded by adiposity.

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)

ABSTRACT

The 2D:4D is thought as a biomarker for prenatal androgen exposure. Some studies have reported a significant difference between the sexes. Earlier studies reported variations in different ethnic and geographic groups. 2D:4D is related to several medical conditions including cardiovascular diseases (CVD) and metabolic syndrome (MetS). The present study investigated the relationships between hand preference, ratio of the index finger (2nd digit: 2D) and ring finger (4th digit: 4D) lengths (2D:4D), height, waist-to-height ratio (WHtR), waist circumference (WC) and weight, body mass index (BMI) in a Turkish population. The study comprised 118 healthy subjects (68 males and 50 females). 2D and 4D finger lengths and some anthropometric traits (height, weight, WC) were measured. The BMI and WHtR were calculated. Hand preference was determined by using a questionnaire (Edinburgh handedness inventory). Geschwind scores were calculated to evaluate the degree of hand preference. The mean age was 26.74 (female 27.86, male 25.89). The right hand 2D:4D was found significantly lower in males (0.9797) than in females (0.9922) (p< 0.001), but the left hand 2D:4D was insignificant. Significant correlations (negative) were observed between the 2D:4D (both left and right) and WHtR; the 2D:4D ratio (both left and right) and WC in males. However, in females, these correlations were insignificant. The R2D:4D was sexually dimorphic in a Turkish population. There were significant differences between strong right (SR) and weak left (WL) in terms of the R2D:4D. However only 5 subject's hand preference was found WL. Therefore, further studies are needed to determine the relationships between hand preference and R2D:4D in Turkish population. Further studies are needed to determine whether a larger sample population alters these possible associations between the ratio of 2D:4D and other investigated traits in a Turkish population.


El 2D:4D está pensado como un biomarcador para la exposición prenatal de andrógenos. Algunos estudios han reportado una diferencia significativa entre sexos. Estudios anteriores informaron variaciones en diferentes grupos étnicos y geográficos. 2D:4D está relacionado con varias afecciones médicas que incluyen enfermedades cardiovasculares (ECV) y síndrome metabólico (MetS). El presente estudio investigó las relaciones entre la preferencia de la mano, la proporción del dedo índice (2º dígito: 2D) y el dedo anular (4º dígito: 4D), longitudes (2D:4D), altura, relación cintura-altura (WHtR), circunferencia de cintura y peso (WC), e índice de masa corporal (IMC), en una población de Turquía. El estudio incluyó 118 sujetos sanos (68 hombres y 50 mujeres). Se midieron longitudes de dedos 2D y 4D y algunos rasgos antropométricos (altura, peso, WC). Se calcularon el IMC y el WHtR. La preferencia de la mano se determinó mediante el uso de una escala (Edinburgh Handedness Inventory). Las puntuaciones de Geschwind se calcularon para evaluar el grado de preferencia de la mano. La edad media fue de 26,74 años (femenino 27,86; masculino 25,89). La mano derecha 2D: 4D se encontró significativamente más baja en los hombres (0,9797) que en las mujeres (0,9922) (p <0,001), pero la mano izquierda 2D: 4D fue no significante. Se observaron correlaciones significativas (negativas) entre la 2D: 4D (izquierda y derecha) y WHtR y la relación 2D: 4D (izquierda y derecha) y WC en hombres. Sin embargo, en las mujeres, estas correlaciones fueron no significantes. El R2D: 4D fue sexualmente dimorfo en una población de Turquía. Hubo diferencias significativas entre la mano derecha fuerte (SR) y la mano izquierda débil (WL) en términos de R2D: 4D. Sin embargo, sólo se encontraron 5 preferencias de mano en el sujeto con WL. Por lo tanto, se necesitan más estudios para determinar las relaciones entre la preferencia de mano y R2D: 4D en la población de Turquía. Se necesitan más estudios para determinar si una muestra mayor altera estas posibles asociaciones entre la proporción de 2D: 4D y otros rasgos investigados en una población de Turquía.

ABSTRACT

Abstract Objective: to investigate the association between hypertension and anthropometric indicators of central obesity, obtained from two anatomical sites in old adults. Methodology: a cross-sectional study including 145 elderly people, from whom socioeconomic and demographic data and anthropometric indicators of central obesity (Waist Circumference [CC] and Abdominal Circumferency [CA]) were obtained, which were considered independent variables. A logistic regression model was used to analyze the associations, and for the discriminatory power of the cutoff points of the anthropometric indicators for hypertension, a Receiver Operating Characteristic (ROC) curve was performed. Comparisons between ROC curves were performed, aiming to identify a significant difference in the discriminatory power of the anthropometric indicators studied. Results: among the 145 individuals, 79 were female (54%) and 66 were male (46%). The results showed a high prevalence of hypertension among men (69.7%) and women (73.4%). Both WC and AC were significantly associated to hypertension in both sexes. The ROC curve parameters indicated that both anthropometric indicators of central obesity exhibit a good discriminatory power for hypertension in this studie. For the studied population, the WC cutoff point for hypertension was > 83.2 cm for men and > 82.6 cm in women, while for CA it was > 85.1 cm and > 85.4 cm in men and women, respectively. Conclusion: AC and WC are significantly associated with hypertension in both sexes, and there is no superiority among them to predict hypertension in the elderly population.


Resumen Objetivo: investigar la asociación entre hipertensión e indicadores antropométricos de obesidad central, obtenidos de dos sitios anatómicos en adultos mayores. Metodología: estudio transversal que incluyó a 145 adultos mayores, de los cuales se obtuvieron datos socioeconómicos y demográficos e indicadores antropométricos de obesidad central (circunferencia de cintura [CC] y circunferencia abdominal [CA]), que fueron considerados variables independientes. Se utilizó un modelo de regresión logística para analizar las asociaciones, además del poder discriminatorio y los puntos de corte para la hipertensión de los indicadores antropométricos, que se obtuvieron a partir de los parámetros de la curva Receiver Operating Characteristic (ROC). Se hicieron comparaciones entre las curvas ROC, con el objetivo de identificar diferencias significativas en el poder discriminatorio de los indicadores antropométricos estudiados. Resultados: de los 145 individuos 79 eran del sexo femenino (54 %) y 66 del masculino (46 %). Los resultados mostraron una alta prevalencia de hipertensión arterial en hombres (69,7 %) y mujeres (734 %). Tanto CC como CA se asociaron significativamente a la hipertensión en ambos sexos. Los parámetros de la curva ROC revelaron que ambos indicadores antropométricos de obesidad central exhiben un buen poder discriminatorio para la hipertensión en la población estudiada. El punto de corte para la CC fue > 83,2 cm para hombres y de > 82,6 cm para mujeres; mientras que para CA fue > 85,1 cm y > 85,4 cm para hombres y mujeres, respectivamente. Conclusión: CA y CC están significativamente asociadas a la hipertensión en ambos sexos, y no hay superioridad entre ellas para predecir la hipertensión en la población anciana.

ABSTRACT

The aim of this study was to examine the association of sedentary behavior with overweight and abdominal obesity in older adults. This was a cross-sectional study with older men and women residing in the municipalities of the Regional Health Superintendency of Uberaba, Minas Gerais. Sedentary behavior was assessed according to the time spent sitting on a weekday and a weekend day. Body mass, height and waist circumference were measured. Excess weight was determined by means of body mass index, while abdominal obesity by waist circumference. Poisson regression analyzis with robust variance were used to examine the association of sedentary behavior with overweight and abdominal obesity. The total sample consisted of 3223 older people (61.3% women), with a mean age of 70 ± 7.26 years. There was no association between quartiles of sedentary behavior and overweight (2nd quartile: PR = 0.99; 95%CI: 0.94­1.05; 3rd quartile: PR = 0.99; 95%CI: 0.93­1.07; 4th quartile: PR = 1.07; 95%CI: 1.00­1.13) and abdominal obesity (2nd quartile: PR = 1.04; 95%CI: 1.00­1.08; 3rd quartile: PR = 1.03; 95%CI: 0.98­1.08; 4th quartile: PR = 0.98; 95%CI: 0.94­1.03) when analyses were adjusted for sociodemographic, health perception and behavioral variables. The sedentary be-havior was not associated with overweight and abdominal obesity in the elderly.


O objetivo deste estudo foi examinar a associação entre o comportamento sedentário e o excesso de peso e a obesidade abdominal em idosos. Trata-se de um estudo transversal com idosos de ambos os sexos, residentes nos municípios da Superintendência Regional de Saúde de Uberaba, Minas Gerais. O comportamento sedentário foi avaliado pelo tempo despendido sentado em um dia de semana e um dia de final de semana. A massa corporal, estatura e circunferência da cintura foram aferidas. O excesso de peso foi determinado por meio do índice de massa corporal e a obesidade abdominal pela e circunferência da cintura. Na estatística, empregou-se análises de regressão de Poisson com variância robusta. Participaram do estudo 3.223 idosos, com média de idade de 70 ± 7,26 anos, sendo 61,3% mulheres. Quando realizadas análises ajustadas pelas variáveis sociodemográficas, percepção de saúde e comportamentais, não foram verificadas associações entre os quartis de comportamento sedentário com o excesso de peso (2º quartil: RP = 0,99; IC95%: 0,94­1,05; 3º quartil: RP = 0,99; IC95%: 0,93­1,07; 4º quartil: RP = 1,07; IC95%: 1,00­1,13) e obesidade abdominal (2º quartil: RP = 1,04; IC95%: 1,00­1,08; 3º quartil: RP = 1,03; IC95%: 0,98­1,08; 4º quartil: RP = 0,98; IC95%: 0,94­1,03). O comportamento sedentário não associou com o excesso de peso e com a obesidade abdominal em idosos

ABSTRACT

ABSTRACT Objective: To investigate the difference in the proportion of students with metabolic syndrome, diagnosed according to different criteria. Methods: The sample consisted of 241 students (136 boys and 105 girls) aged 10 to 14 years, from public and private schools in Paranavaí, Paraná. We used three distinct diagnostic criteria for metabolic syndrome, considering the presence of at least three of the following risk factors: increased waist circumference, hypertension, fasting hyperglycemia, low HDL-C, and elevated triglycerides. Results: The prevalence of metabolic syndrome found was 1.7% (confidence interval of 95% - 95%CI 0-3.3) for the IDF criterion; 3.3% (95%CI 1.0-5.6) for Cook; and 17.4% (95%CI 12.6-22.3) for Ferranti. Analyzing the criteria in pairs, the agreement between IDF and Cook was 97.5% (k=0.95); between IDF and Ferranti, 83.4% (k=0.67); and between Cook and Ferranti, 85.9% (k=0.72). Onlyone student (0.4%) was diagnosed with metabolic syndrome solely by the IDF criterion, while 34 (14.1%) were diagnosed exclusively by Ferranti. The comparison of the three criteria showed that Ferranti presented the highest proportion of metabolic syndrome (p<0.001), and Cook had a greater proportion than IDF (p<0.001). Conclusions: We found a significant difference in the proportion of metabolic syndrome in the three criteria. The choice of which criterion to use can compromise not only the percentage of metabolic syndrome prevalence but also interfere in strategies of intervention and prevention in children and adolescents with and without metabolic syndrome, respectively.


RESUMO Objetivo: Investigar a diferença na proporção de escolares com síndrome metabólica diagnosticada segundo diferentes critérios. Métodos: Duzentos e quarenta e um escolares (136 meninos e 105meninas), com idade entre dez e 14 anos, das redes pública e privada de Paranavaí, Paraná. Foram utilizados três diferentes critérios para o diagnóstico da síndrome metabólica, considerando a presença de, ao menos, três dos seguintes fatores de risco: circunferência de cintura aumentada, hipertensão arterial, hiperglicemia em jejum, baixo nível de HDL-C e triglicerídeos elevado. Resultados: A prevalência de síndrome metabólica encontrada foi de 1,7% (intervalo de confiança de 95% - IC95% 0-3,3), para o critério de IDF; 3,3% (IC95% 1,0-5,6) em Cook; e 17,4% (IC95% 12,6-22,3) em Ferranti. Na verificação dos critérios em pares, a concordância entre IDF e Cook foi de 97,5% (k=0,95); entre IDF e Ferranti, 83,4% (k=0,67); e entre Cook e Ferranti, 85,9% (k=0,72). Em apenas um aluno (0,4%) a síndrome metabólica foi diagnosticada exclusivamente pelo critério de IDF, e em 34 alunos (14,1%), pelo critério de Ferranti. A comparação entre os três critérios mostrou que o de Ferranti apresentou maior proporção de síndrome metabólica que os demais (p<0,001), e o de Cook maior proporção em relação ao da IDF (p<0,001). Conclusões: Houve diferença significante na proporção de síndrome metabólica nos três critérios. A escolha do critério a ser utilizado pode comprometer não apenas o percentual de prevalência de síndrome metabólica, mas também atrapalhar as estratégias de prevenção e intervenção em crianças e adolescentes com e sem síndrome metabólica, respectivamente.

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 Objetivo: Elaborar pontos de corte de circunferência da cintura de acordo com o estadiamento puberal para identificar sobrepeso em adolescentes. Métodos: Trata-se de um estudo longitudinal, aprovado pelo Comitê de Ética em Pesquisa, com 557 adolescentes, de 10 a 15 anos de idade, selecionados em escolas públicas. Aferiram-se as medidas de circunferência de cintura, braço, pescoço e quadril, percentual de gordura, massa corporal, estatura e pressão arterial. Para determinar a maturação sexual, foi utilizada a autoavaliação da escala de Tanner. Aplicou-se a curva ROC (Receiver Operating Characteristic Curve) para determinar: poder preditivo, sensibilidade, especificidade e os pontos de corte de circunferência de cintura para identificação de sobrepeso. Resultados: Observou-se correlação positiva entre circunferência de cintura e massa corporal, índice de massa corporal (IMC), circunferência do braço e quadril, razão cintura/quadril e pressão arterial em ambos os sexos. Os pontos de corte para circunferência de cintura de acordo com o estadiamento puberal para identificação de sobrepeso que apresentaram maior desempenho na curva ROC foram: 71,65 cm para meninas pré-púberes, 67,90 cm para meninas púberes, 70,25 cm para meninas pós-púberes e 66,45 cm para meninos púberes. Faixa etária, massa corporal, estatura, IMC, porcentagem de gordura, circunferência do braço e do quadril foram considerados fatores preditores da circunferência da cintura alterada. Conclusões: Os pontos de corte de circunferência da cintura de acordo com o estadiamento puberal demonstraram excelente desempenho para a identificação de sobrepeso, podendo ser considerados fidedignos para a população de adolescentes brasileiros, uma vez que utilizar apenas a idade cronológica na adolescência pode subestimar o estado nutricional.


ABSTRACT Objective: To establish waist circumference cut off points according to pubertal staging to identify overweight in adolescents. Methods: Longitudinal study approved by the Ethics Research Committee and conducted with 557 adolescents, aged 10 to 15 years old, selected from public schools. Waist, arm, neck and hip circumferences, body fat percentage, body mass index (BMI), height and blood pressure were measured. Pubertal staging was evaluated by Tanner self assessment scale. The Receiver Operating Characteristic Curve (ROC curve) was used to determine predictive power, sensitivity, specificity and waist circumference cut off points to detect overweight. Results: There was a positive correlation between waist circumference and weight, BMI, upper arm and hip circumferences, waist-to-hip ratio and blood pressure in both sexes. Cut off points for waist circumference according to pubertal stage as related to overweight in adolescents with the best performances in ROC curve were: 71.65 cm for prepubescent girls, 67.90 cm for pubescent girls, 70.25 cm for post pubescent girls, and 66.45 cm for pubescent boys. Age, weight, height, BMI, body fat percentage, arm and hip circumferences were associated to altered waist circumference. Conclusions: The establishment of cut off points for waist circumference according to pubertal staging was proven a good means to identify overweight. These cut off points can be considered reliable for the Brazilian adolescent population, as the isolated use of chronological age in adolescents may underestimate their nutritional status.

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.

ABSTRACT

BACKGROUND: This study aimed to evaluate the association between metabolic syndrome and depression severity based on the Patient Health Questionnaire 9 (PHQ-9) score in men aged >50 years.METHODS: In this study, we used data of 1,230 individuals from the Sixth Korea National Health and Nutrition Examination Survey (KNHANES VII-1) 2016 conducted by the Korea Centers for Disease Control and Prevention. We diagnosed metabolic syndrome in accordance with National Cholesterol Education Program-Adult Treatment Panel III guidelines using waist circumference, blood pressure, fasting serum triglyceride level, high-density lipoprotein cholesterol level, and fasting glucose level in men aged >50 years (mean±standard deviation: 64.6±8.8 years), and their PHQ-9 scores were classified as mild and severe (cutoff, 10).RESULTS: The mean waist circumference, fasting glucose level, triglyceride level, and high-density lipoprotein cholesterol level were 87.1±8.2 cm, 109.8±28.3 mg/dL, 155.9±123.9 mg/dL, and 46.5±12.2 mg/dL, respectively. The mean systolic and diastolic blood pressures were 124.7±15.9 mmHg and 76.2±10.7 mmHg, respectively. The mean body mass index, was 24.2±2.9 kg/m². The prevalence of metabolic syndrome was 43.7%. The mean PHQ-9 score was 2.0±3.3. The prevalence of severe depression with a score of >10 was 4.2%. Metabolic syndrome and depression were related (P<0.05). The adjusted odds ratio for metabolic syndrome was 0.5 (95% confidence interval [CI], 0.3–0.9). However, age (95% CI, 0.9–1.0), sleep duration during weekdays (95% CI, 0.9–1.0), and sleep duration during weekends (95% CI, 0.9–1.0) were not related.CONCLUSION: Metabolic syndrome was associated with depression in men aged >50 years in this study.

ABSTRACT

BACKGROUND: Vitamin D has been known to play an important role in calcium homeostasis and bone metabolism. It has also been implicated in diabetes mellitus, cardiovascular disease, and immune diseases. Several cross-sectional studies conducted worldwide have found that vitamin D is negatively correlated with obesity. In Korea, however, the results of similar studies were found to be inconsistent.METHODS: The study consisted of 585 adults over 18 years of age, who visited a health promotion center at a university hospital from March, 2015 to February, 2016 and their serum vitamin D levels were recorded. They were divided into two groups according to their sex. The correlation coefficients were calculated using Pearson correlation analysis between obesity and vitamin D. Finally, subjects with vitamin D levels less than <20 ng/mL were classified as deficient. Bivariate logistic regression analysis was used to determine the odds ratio of vitamin D deficiency.RESULTS: We observed a significant negative correlation between obesity and vitamin D (P<0.05) among the women but not in the men. The following are the details of the findings: ≥25 in body mass index (model 3 adjusted odds ratio [OR], 4.11; 95% confidence interval [CI], 1.59–10.67), ≥85 cm in waist circumference (model 3 adjusted OR, 1.81; 95% CI, 1.02–4.01), ≥30% in body fat (model 3 adjusted OR, 2.29; 95% CI, 1.17–4.62).CONCLUSION: Based on the results of this study, we suggest that obesity and vitamin D are negatively correlated and that obesity in women predisposes them to vitamin D deficiency.

ABSTRACT

BACKGROUND: Hyperuricemia refers to an excess of uric acid in the blood and is associated with gouty arthritis, hypertension, metabolic syndrome, atrial fibrillation, kidney stones, insulin resistance (IR), and type 2 diabetes mellitus. Previous studies have used the homeostatic model assessment of IR (HOMA-IR), a well-known index of IR, to investigation the correlation between serum uric acid levels and IR. However, difficulty with measuring insulin levels limits the clinical applicability of the HOMA-IR index. This study investigated the correlation between hyperuricemia and the triglyceride glucose (TyG) index.METHODS: We used data from the Seventh Korea National Health and Nutrition Examination Survey, 2016. The study population included adults without diabetes aged >19 years. The TyG index, which serves as an indicator of IR, was calculated using fasting serum glucose and triglyceride levels to investigate the correlation between the TyG index and hyperuricemia. Pearson's correlation coefficient and analysis of covariance were used for statistical analysis, which was performed using IBM SPSS software.RESULTS: A statistically significant correlation was observed between serum uric acid levels and the TyG index. After adjustment for factors that may affect IR (age, body mass index, waist circumference, and systolic and diastolic blood pressures), we observed that the TyG index was significantly higher in the hyperuricemia than in the non-hyperuricemia group (8.96 vs. 8.54, P < 0.001).CONCLUSION: Serum uric acid levels were significantly correlated with IR assessed using the TyG index in adults without diabetes aged >19 years.

ABSTRACT

BACKGROUND: Vitamin D is a hormone required by the human body. Several studies have shown that vitamin D helps improve muscle strength. The purpose of our study was to examine the relationship between vitamin D levels and muscle strength in Korean adults.METHODS: The Korea National Health and Nutrition Examination Survey was conducted in the Korean population from 2009 to 2011. We surveyed 859 men and 944 women aged between 20 and 65 years. We investigated age, blood pressure, exercise frequency, heart rate, height, body weight, waist circumference, body mass index, serum vitamin D level, and hand grip strength. We analyzed the relationship between serum vitamin D level and hand grip strength using the linear regression test.RESULTS: On statistical analysis, vitamin D levels showed a significantly positive correlation with only grip strength. However, after adjusting for all other variables, no positive correlation was observed between vitamin D levels and grip strength.CONCLUSION: No significant correlation was observed between vitamin D levels and grip strength. Further research is needed on this topic.
