Se presenta el caso de un niño de 3 años con diagnóstico de asma, rinitis alérgica, características craneofaciales dismórficas e infecciones respiratorias altas y bajas recurrentes, manejado como asma desde un inicio. Como parte del estudio de comorbilidades, se decide realizar una prueba del sudor que sale en rango intermedio y más tarde se encuentra una mutación, donde se obtiene un resultado positivo para una copia que se asocia a fibrosis quística. Se revisará el caso, así como el diagnóstico, clínica y tratamiento del síndrome metabólico relacionado con el regulador de conductancia transmembrana de fibrosis quística (CRMS).

We present the case of a 3-year-old boy with a diagnosis of asthma, allergic rhinitis, dysmorphic craniofacial characteristics and recurrent upper and lower respiratory infections, managed as asthma from the beginning. As part of the study of comorbidi-ties, it was decided to carry out a sweat test that came out in the intermediate range and later one mutation was found, where a positive result was obtained for a copy that is associated with cystic fibrosis. The case will be reviewed, as well as the diagnosis, symptoms and treatment of the metabolic syndrome related to the cystic fibrosis trans-membrane conductance regulator (CRMS).

El Estimador de Sensibilidad Insulínica de Punto Único (SPISE) supera a marcadores antropométricos de uso rutinario en la pesquisa de riesgo cardiometabólico asociado a obesidad: un estudio en adolescentes de la Región Metropolitana / The single Point Insulin Sensitivity Estimator (SPISE) outperforms routine anthropometric markers in the screening of obesity-related cardiometabolic risk: a study in adolescents from the Metropolitan Region

El Estimador de Sensibilidad a la Insulina de Punto Único (SPISE) es un biomarcador de sensibilidad a la insulina comparable al Índice de Matsuda. Se estima utilizando el IMC y los niveles de triglicéridos y HDL. El objetivo de este estudio fue comparar el rendimiento diagnóstico de SPISE con el de otros marcadores antropométricos de uso rutinario, como el IMC y la relación cintura | talla, en la pesquisa de insulinoresistencia (IR) y Síndrome Metabólico (MetS) en una muestra de 901 adolescentes de 11 a 16 años. En todos ellos se midió peso, talla, cintura, presión arterial, perfil lipídico, insulina y glicemia. La IR se diagnosticó con el HOMA-IR y el MetS con el criterio de Cook. Un zIMC ≥2.0 DE, un índice cintura/ talla ≥0.54 y un SPISE ≤ 5.4 fueron los puntos de corte utilizados para evaluar el rendimiento de estos marcadores en el diagnóstico de IR y MetS. No hubo diferencias por sexo en la prevalencia de obesidad, IR y MetS. Tanto en hombre como en mujeres, SPISE mostro una mejor capacidad para predecir el MetS (AUC: 0.95 y 0.89, respectivamente) e IR (AUC: 0.83 y 0.79, respectivamente) comparado con el rendimiento diagnóstico de la relación cintura | talla y el IMC-z. De igual manera, el SPISE mostro una mayor sensibilidad para identificar a los portadores de MetS e IR (96% y 75% en varones y 81% y 67% en mujeres, respectivamente). SPISE mostró una mejor capacidad para identificar el riesgo cardiometabólico asociado a la malnutrición por exceso al compararlo con otros indicadores de uso frecuente en clínica. Un índice de SPISE ≤5.4 fue un mejor predictor de MetS e IR que un IMC ≥2.0 DE y una relación cintura | talla ≥0.54.

The Single Point Insulin Sensitivity Estimator (SPISE) is a biomarker of insulin sensitivity comparable to the Matsuda Index. It is estimated using data on BMI, TG, and HDL. We aim to compare the diagnostic performance of SPISE with other routinely used anthropometric markers, such as BMI and waist-to-height ratio, in diagnosing insulin resistance (IR) and Metabolic Syndrome (MetS) in adolescents from 11 to 16 years. Weight, height, waist, blood pressure, lipid profile, insulin, and glycemia were measured. IR was diagnosed with the HOMA-IR and the MetS with the Cook criteria. A BMIz ≥2.0 SD, a waist-to-height ratio ≥0.54, and a SPISE ≤ 5.4 were the cut-off points used for diagnosing IR and MetS. There were no sex differences in the prevalence of obesity, IR, and MetS. In both males and females, SPISE showed a better ability to predict MetS (AUC: 0.95 and 0.89, respectively) and IR (AUC: 0.83 and 0.79, respectively) compared to the waist-to-height ratio and BMI-z. Similarly, SPISE showed greater sensitivity to identify adolescents with MetS and IR (96% and 75% in men and 81% and 67% in women, respectively) than the waist-to-height ratio and BMI-z. SPISE performed better in identifying obesity-related cardiometabolic risk than other frequently used clinical indicators. A SPISE index ≤5.4 was a better predictor of MetS and RI than a BMI ≥2.0 SD and a waist-to-height ratio ≥0.54.

ABSTRACT Objective: to evaluate the prevalence of metabolic syndrome and associated factors in nursing professionals working in oncology. Method: cross-sectional study with 231 nursing professionals from a high complexity oncology center in the State of Rio de Janeiro, Brazil, between June 2013 and June 2015. An interview was carried out to collect sociodemographic, professional, personal history, habits and lifestyles, and health conditions data. Waist circumference, weight, height, casual blood pressure, and Ambulatory Blood Pressure Monitoring were performed, in addition to fasting plasma glucose, triglycerides, and high-density lipoprotein. Metabolic syndrome was evaluated according to the I Brazilian Guideline for the Diagnosis and Treatment of Metabolic Syndrome. Poisson regression with robust variance was performed, the outcome being the presence or not of metabolic syndrome. Results: there was a 25.1% prevalence of metabolic syndrome and this condition was associated with longer professional training (4.0%; 95%CI: 1.05-1.07), with higher diastolic pressure in Ambulatory Blood Pressure Monitoring during sleep (3.0%; 95%CI:1.01-1.05), overweight (2.84%; 95%CI:1.93-6.70), and obesity (4.94%; IC95%: 2.08-11.77). Conclusions: there was a high prevalence of metabolic syndrome among the evaluated professionals, and an association between excess weight and changes in pressure during sleep. The results point to the need for interventions to control risk factors for chronic non-communicable diseases in the studied population.

Cutoff point of TyG index for metabolic syndrome in Brazilian farmers

ABSTRACT Objective: Thus, the aim of this study was to identify the cutoff point of the TyG index for the diagnosis of insulin resistance (IR), according to two different diagnostic criteria of metabolic syndrome in a rural Brazilian population. Materials and methods: The study population consisted of 790 family farmers from 18 to 59 years old. The triglyceride-glucose index (TyG index) was calculated, and the Metabolic Syndrome was defined using the NCEP-ATPIII and IDF criteria. Mann-Whitney U test was used to analyze the association of quantitative and qualitative variables. When the qualitative variable had three or more categories, the comparison between the means was performed by the Kruskal-Wallis test (using the Mann-Whitney U Test two by two to identify the differences). For correlations, Spearman's correlation test was used. The cutoff values of TyG index for MetS were obtained using the Receiver Operating Characteristic (ROC) curve analysis with the area under the curve (AUC) and the Youden Index. Results: The median TyG values increased according to the aggregation of the components of MetS. The AUCs and Youden's cutoff point for TyG index according to the NCEP and IDF diagnostic criteria were 0.873, Ln 4.52 (sensitivity: 84.30%; specificity: 75.75%), and 0.867, Ln 4.55 (sensitivity: 80.0%; specificity: 79.82%), respectively. Conclusion: A cutoff point of Ln 4.52 was defined, and it can be used both in clinical practice and epidemiological studies. It represents an important tool for promotion, protection and recovery health of rural populations.

Desórdenes del metabolismo glucídico y síndrome metabólico en pacientes de covid-19 / Glucide metabolism disorders and metabolic syndrome in COVID-19 patients

RESUMEN El síndrome metabólico comprende un conjunto de factores de riesgo cardiovascular asociado a resistencia a la insulina, que propicia la aparición de enfermedad cardiovascular y de diabetes mellitus tipo 2. Su etiología se atribuye a la combinación de factores genéticos y ambientales, asociados al estilo de vida, que favorecen un estado proinflamatorio y protrombótico que empeora el cuadro clínico de los pacientes con covid-19. El objetivo de la revisión consistió en analizar el estado actual del conocimiento científico en las investigaciones sobre la interrelación entre los desórdenes del metabolismo glucídico y el síndrome metabólico, asociados a la condición proinflamatoria exacerbada en pacientes de covid-19. Se hicieron búsquedas en las bases de datos PubMed, SciELO, ClinicalKey y LILACS. Al proceso proinflamatorio generado por malos hábitos alimentarios, la sobrealimentación calórica de alto índice glicémico, y estilos de vida sedentarios, se atribuye un papel relevante en la patogénesis del síndrome metabólico, así como en sus posibles complicaciones en pacientes de covid-19 con comorbilidades asociadas. Es posible reducir la condición inflamatoria del síndrome metabólico mediante modificaciones en el estilo de vida y hábitos alimentarios, que prevengan la obesidad y sus efectos en la resistencia a la insulina, lo cual propicia reducir la gravedad asociada a los procesos inflamatorios inherentes (AU).

ABSTRACT Metabolic syndrome includes a set of cardiovascular risk factors associated with resistance to insulin, favoring the appearance of cardiovascular disease and diabetes mellitus type 2. Its etiology is attributed to the combination of genetic and environmental factors, associated to lifestyle, and favoring a proinflammatory and prothrombotic status that worsens the clinical characteristics of the patients with COVID-19. The objective of the review was to analyze the current state of the scientific knowledge in research on the interrelationship between glucide metabolism disorders and metabolic syndrome, associated with the exacerbated proinflammatory condition in COVID-19 patients. Searches were conducted in PubMed, SciELO, CinicalKey, and LILACS databases. A relevant role in the metabolic syndrome pathogenesis is attributed to the inflammatory process generated by poor eating habits, high caloric overfeeding, and to sedentary lifestyle, and also to possible complications with associated comorbidities in COVID-19 patients. It is possible to reduce the metabolic syndrome inflammatory condition through life style and alimentary habits changes that prevent obesity and its effects on insulin resistance and propitiate the reduction of the disease severity associated with the inherent inflammatory processes (AU).

Objetivo: Analisar os indicadores laboratoriais de saúde em usuários de uma Unidade Básica de Saúde com e sem o diagnóstico para a diabetes e hipertensão. Métodos: A amostra foi de 231 usuários de uma unidade básica de saúde da cidade de Santarém-PA, maiores de idade, que foram agrupados em pacientes com DM/HAS (DM/HAS; n=144), e sem o diagnóstico para DM/HAS (AUS; n=87). As coletas envolveram informações socioeconômicas, clínicas e laboratoriais. Os dados foram tratados com estatística descritiva e inferencial, adotando-se p<0.05. Resultados: Tanto no DM/HAS como no AUS predominou o sexo feminino, estado civil casado, com vínculo empregatício, cor de pele parda, com 4-7 anos de estudo, renda de 1-2 salários, não tabagistas, não etilista e faixa etária de 38-77 anos. A HAS foi a doença mais presente de forma geral, bem como por sexo. Identificou-se no DM/HAS valores menores para a taxa de filtração glomerular (TFG) e maiores valores para a glicemia, triglicerídeos, colesterol total, LDL-c e não HDL-c. Conclusão: De acordo com a proposta desenvolvida, destaca-se que os usuários com DM/HAS apresentam associação positiva para valores alterados de glicemia, colesterol total, não HDL-c, triglicerídeos, TFG e para a presença da síndrome metabólica e risco cardiovascular moderado/alto.

Introduction: Users of the health system with chronic non-communicable diseases must be constantly monitored to avoid complications in their health status. Objective: Analyze laboratory health indicators in users of a Basic Health Unit with and without a diagnosis for diabetes and hypertension. Methods: The sample consisted of 231 users of a basic health unit in the city of Santarém-PA, all of them of age, grouped into patients with DM/SAH (DM/SAH; n=144), and without the diagnosis for DM/SAH (ABS; n=87). The collections involved socioeconomic, clinical, and laboratory information. The data were treated with descriptive and inferential statistics, adopting p <0.05. Results: In both DM/SAH and ABS groups, there was a predominance of female individuals, married status, employed, brown skin color, with 4-7 years of study, income of 1-2 salaries, non-smokers, non-alcoholic drinkers, and aged between 38-77 years. SAH was the most common disease in general, as well as when analyzing by gender. Lower values for the glomerular filtration rate (GFR) were identified in the DM/SAH and higher values for the glycemia, triglycerides, total cholesterol, LDL-c, and non-HDL-c. Conclusion: According to the proposal of this paper, it is noteworthy that users with DM/SAH have a positive association for altered values of blood glucose, total cholesterol, non-HDL-c, triglycerides, GFR, and for the presence of metabolic syndrome and moderate/high cardiovascular risk.

Predicting Metabolic Syndrome Using Anthropometric Indices among Chinese Adolescents with Different Nutritional Status: A Multicenter Cross-sectional Study / 生物医学与环境科学（英文）

Objective@#To evaluate the predictive performance of anthropometric indices for metabolic syndrome (MetS) among Chinese adolescents with different nutritional status.@*Methods@#We recruited 9,513 adolescents aged 10-18 years from seven provinces in China during September 2014. Anthropometric indices and blood pressure were measured at recruitment, and blood samples were collected for determining fasting plasma glucose and lipid profile. Receiver operating characteristic (ROC) analyses were used to assess the predictive performance of anthropometric indices, including body mass index (BMI) percentile, waist circumference percentile, waist-height ratio, and waist-hip ratio.@*Results@#Overall, the four anthropometric indices showed good accuracy for predicting MetS with areas under ROC curves (AUCs) ranging from 0.86 to 0.94; similar AUCs ranging from 0.73 to 0.99 were observed for participants with normal weight. The performance of all four indices was poor in overweight and obese participants, with AUCs ranging from 0.66 to 0.77 and from 0.60 to 0.67, respectively. Waist circumference showed relatively better performance in all the subgroup analyses.@*Conclusions@#We suggest using anthropometric indices with the cutoff values presented here for predicting MetS in the overall and normal-weight adolescent population, but not in the overweight and obese adolescent population where more specific screening tests are required.

Repercussões metabólicas: quais, como e por que investigar? / Metabolic repercussions: which ones, how and why investigate?

A síndrome dos ovários policísticos (SOP) é frequentemente acompanhada de distúrbio metabólico, principalmente dos carboidratos e dos lipídeos, aumentando o risco de síndrome metabólica. Por essa razão, alguns investigadores ainda denominam a SOP de síndrome metabólica-reprodutiva. O objetivo deste capítulo é descrever as principais repercussões metabólicas, bem como como investigá-las e saber como suas consequências podem ser deletérias para a saúde da mulher. Esta é uma revisão narrativa mostrando a implicação do metabolismo dos carboidratos e dos lipídeos nas dislipidemias, bem como da síndrome metabólica sobre o sistema reprodutor, e o risco cardiovascular da mulher com SOP. Conclui-se que o manejo adequado dos distúrbios metabólicos na SOP é benéfico a curto e a longo prazo tanto para o sistema reprodutor quanto para o cardiovascular.(AU)

Performance of adiposity indicators in predicting metabolic syndrome in older adults

ABSTRACT Objective: To evaluate the association between some indicators of adiposity and markers of metabolic disorder, evaluate their performance in predicting metabolic syndrome (MetS), and identify their cutoff values among older adults, both in the overall sample and according to sex. Subjects and methods: Cross-sectional study in 159 older men and women. MetS was defined according to the harmonized criteria. The assessments included waist circumference (WC), waist-to-height ratio (WHtR), conicity index (C index), lipid accumulation product (LAP), visceral adiposity index (VAI), body mass index (BMI), A body shape index (ABSI), area under the receiver operating characteristic curve (AUC), sensitivity, and specificity. Results: LAP and WHtR resulted in the largest AUC values (>0.80). In both sexes, the best indicators were LAP, WC, and WHtR. Both LAP and WHtR presented the highest Youden's index values in the overall sample, with cutoff values of approximately 46.9 (sensitivity 75.0%, specificity 76.7%) and 0.56 (sensitivity 79.3%, specificity 69.8%), respectively. When analyzed by sex, BMI, WC, WHtR, and LAP yielded the highest Youden's index values for the prediction of MetS in older women. Conclusion: The indicators LAP, WC, and WHtR performed well in identifying the presence of MetS in older women and could be used to individually or collectively assess and monitor MetS.

Biochemical predictors for metabolic syndrome in preterm infants according to weight ratio

ABSTRACT Objective Prematurity and low birth weight predispose preterm infants to cardiovascular disease in later life. Is the metabolic profile of these children impacted by the relation between birth weight and gestational age (GA)? This study aimed to evaluate whether the relationship between birth weight and GA of preterm infants has a positive correlation with the metabolic profile from birth to the sixth month of corrected age. Subjects and methods This is a longitudinal, prospective study with a cohort of 70 preterm and 54 term infants, who were enrolled in the study and shared into two groups: Appropriate for GA (AGA) and Small for GA (SGA), both classified at birth by Fenton and Kim curves. Longitudinal evaluation of anthropometry measures and blood samples of total cholesterol, glucose, triglycerides, and insulin were collected at birth, NICU discharge, and the sixth month of corrected age. Data were analyzed using descriptive and inferential statistical analysis (ANOVA, Fisher test, Shapiro-Wilk, and Cochran test). The effect size was 0.15, power was 0.92, and confidence interval 95%. Results No significant statistical differences were observed in relation to biochemical tests between AGA and SGA groups. However, a significant increase in triglyceride results above the reference values for age in the SGA group was observed throughout the follow-up. Conclusions Changes observed in the preterm infant metabolic profile show no correlation with adequacy of birth weight. Preterm lipid profile requires continuous evaluation at follow-up, due to the increased cardiovascular risk in later life.

Síndrome metabólico, hígado graso no alcohólico y hepatocarcinoma / Metabolic syndrome, nonalcoholic fatty liver disease and hepatocellular carcinoma

En las últimas décadas, los cambios en el estilo de vida pro-vocaron un incremento en la prevalencia del síndrome meta-bólico y que la enfermedad por hígado graso no alcohólico (nonalcoholic fatty liver disease, NAFLD sus siglas en inglés) se convierta en la enfermedad hepática crónica más fre-cuente en todo el mundo. Los componentes del síndrome metabólico no son sólo altamente prevalentes en pacientes con hígado graso no alcohólico, sino que a la vez aumentan el riesgo de desarrollarlo. Esta relación bidireccional ha sido claramente establecida. Asimismo se considera que NAFLD podría ser el componente hepático del síndrome metabólico. Aunque NAFLD se considera principalmente una enfermedad benigna, puede progresar a fibrosis hepática grave y carcino-ma hepatocelular (CHC), incluso se encontraría este último en hígados no cirróticos. El objetivo de esta revisión es determinar los procesos fisio-patológicos comunes a estas entidades, cuáles son las estra-tegias diagnósticas recomendadas y cuáles las intervenciones terapéuticas actualmente aprobadas.

Tri-ponderal mass index and body mass index in prediction of pediatric metabolic syndrome: the CASPIAN-V study

ABSTRACT Objective Body mass index (BMI) and tri-ponderal mass index (TMI) are anthropometric measures to evaluate body adiposity in the various age groups. The present study aims to compare the predictive value of TMI and BMI for metabolic syndrome (Mets) in children and adolescents of both genders. Subjects and methods A cross-sectional study conducted on 3731 Iranian children and adolescents aged 7-18 years obtained from the fifth survey of 'Childhood and Adolescence Surveillance and Prevention of Adult Non-communicable Disease' (CASPIAN-V) study. The predictive value of BMI and TMI for MetS were determined using Receiver-operator curves. Logistic regression analysis was used to assess the relationship between these indices with MetS. Results 52.6% of participants were boys. The mean (standard deviations) age for boys and girls were 12.62 (3.02) and 12.25 (3.05) years, respectively. In boys, the area under the curve (AUC) of TMI was greater than BMI for all age groups. AUC of TMI was also greater than BMI for age group of 11-14 years (AUC = 0.74; 95% CI (0.67, 0.81)) in girls. Furthermore, our findings showed that odds ratio of Mets for TMI was greater than BMI in age groups of 11-14 years (OR = 1.33 vs 1.22) and 15-18 years (1.16 vs 1.15) in girls and boys, respectively. Conclusion TMI and BMI had moderate predictive value for identifying MetS. However, TMI was a better predictor of MetS than BMI in both genders, especially in age groups of 11-14 and 15-19 years for girls and boys.

Síndrome metabólica em adolescentes: comparação entre três diferentes critérios diagnósticos / Metabolic syndrome in adolescents: comparison between three different diagnostic criteria

Objetivo: verificar a diferença na proporção de adolescentes com síndrome metabólica, identificada por três diferentes critérios diagnósticos. Metodologia: estudo descritivo e transversal, realizado com 716 adolescentes de 10 a 19 anos, de escolas municipais e estaduais da cidade de Picos, Piauí. Para a coleta de dados utilizou-se um instrumento para verificação de dados socioeconômicos, antropométricos, bioquímicos e da pressão arterial. A síndrome metabólica foi definida por três critérios diagnósticos diferentes: International Diabetes Federation (IDF), Cook e Ferranti. Para a análise da diferença entre as médias utilizouse o teste t, e o coeficiente Kappa para a concordância entre os critérios. Resultados: A síndrome foi observada em 3,1, 8,5 e 1,4 % dos adolescentes, de acordo com as definições de Cook, Ferranti, e da International Diabetes Federation, respectivamente. Na verificação dos critérios em pares a concordância entre: IDF e Cook foi 98,3% (Kappa = 0,618; p = 0,000); IDF e Ferranti foi 91,4% (Kappa = 0,228; p = 0,000); Cook e Ferranti foi 92,9% (Kappa = 0,425; p = 0,000). Conclusão: Foi possível observar considerável diferença entre os critérios para o diagnóstico, sugerindo pouca prevalência da síndrome por falta de consenso dos critérios diagnósticos em adolescentes.

Objective: To verify the difference in the proportion of adolescents with metabolic syndrome, identified by three different diagnostic criteria. Methodology: Descriptive and cross-sectional study conducted with 716 adolescents aged 10 to 19 years old from state and municipal schools in the city of Picos, Piauí. For data collection, an instrument was used to verify socioeconomic, anthropometric, biochemical and blood pressure data. Metabolic syndrome was defined by three different diagnostic criteria: International Diabetes Federation (IDF), Cook and Ferranti. For the analysis of the difference between the averages we used the ttest and the Kappa coefficient for agreement between the criteria. Results: The syndrome was observed in 3.1, 8.5 and 1.4% of adolescents, according to the definitions of Cook, Ferranti, and the International Diabetes Federation, respectively. In the paired criteria verification the agreement between IDF and Cook was 98.3% (Kappa = 0.618; p=0.000); IDF and Ferranti was 91.4% (Kappa = 0.228; p=0.000); Cook and Ferranti was 92.9% (Kappa = 0.425; p=0.000). Conclusion: It was possible to observe considerable difference between the criteria for the diagnosis of the syndrome, suggesting low prevalence of the syndrome due to lack of consensus on diagnostic criteria in adolescents.

Homeostasis model assessment of insulin resistance (HOMA-IR) and metabolic syndrome at baseline of a multicentric Brazilian cohort: ELSA-Brasil study / Modelo de avaliação da homeostase de resistência à insulina (HOMA-IR) e síndrome metabólica na linha de base de uma coorte brasileira multicêntrica: estudo ELSA-Brasil / Modelo homeostático para evaluar la resistencia a la insulina (HOMA-IR) y síndrome metabólico en la línea de base de una cohorte brasileña multicéntrica: estudio ELSA-Brasil

Abstract: Homeostasis model assessment of insulin resistance (HOMA-IR) is a method to measure insulin resistance. HOMA-IR cut-offs for identifying metabolic syndrome might vary across populations and body mass index (BMI) levels. We aimed to investigate HOMA-insulin resistance cut-offs that best discriminate individuals with insulin resistance and with metabolic syndrome for each BMI category in a large sample of adults without diabetes in the baseline of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Among the 12,313 participants with mean age of 51.2 (SD 8.9) years, the prevalence of metabolic syndrome was 34.6%, and 60.1% had overweight or obesity. The prevalence of metabolic syndrome among normal weight, overweight and obesity categories were, respectively, 13%, 43.2% and 60.7%. The point of maximum combined sensitivity and specificity of HOMA-IR to discriminate the metabolic syndrome was 2.35 in the whole sample, with increasing values at higher BMI categories. This investigation contributes to better understanding HOMA-IR values associated with insulin resistance and metabolic syndrome in a large Brazilian adult sample, and that use of cut-off points according to ROC curve may be the better strategy. It also suggests that different values might be appropriate across BMI categories.

Resumo: O modelo de avaliação da homeostase da resistência à insulina (HOMA-IR) é um método para medir a resistência à insulina. Os pontos de corte do HOMA-IR para identificar a síndrome metabólica podem variar entre as populações e os níveis de índice de massa corporal (IMC). Nosso objetivo foi investigar os pontos de corte do HOMA-IR que melhor discriminam indivíduos com resistência à insulina e com síndrome metabólica para cada categoria de IMC em uma grande amostra de adultos sem diabetes na linha de base do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). Entre os 12.313 participantes com média de idade de 51,2 (DP 8,9) anos, a prevalência de síndrome metabólica foi de 34,6%, e 60,1% apresentavam sobrepeso ou obesidade. As prevalências de síndrome metabólica nas categorias de peso normal, sobrepeso e obesidade foram, respectivamente, 13%, 43,2% e 60,7%. O ponto de máxima sensibilidade e especificidade combinadas do HOMA-IR para discriminar a síndrome metabólica foi de 2,35 em toda a amostra, com valores crescentes nas categorias de IMC mais elevadas. Esta investigação contribui para o melhor entendimento dos valores de HOMA-IR associados à resistência à insulina e síndrome metabólica em uma grande amostra de adultos brasileiros, e que o uso de pontos de corte de acordo com a curva ROC pode ser a melhor estratégia. Também sugere que valores diferentes podem ser apropriados nas categorias de IMC.

Resumen: El modelo homeostático para evaluar la resistencia a la insulina (HOMA-IR) es un método para medir la resistencia a la insulina. Los cortes HOMA-IR para identificar el síndrome metabólico pueden variar entre las poblaciones y los niveles del índice de masa corporal (IMC). El objetivo fue investigar los cortes de HOMA-IR que mejor discriminaban individuos con resistencia a la insulina y con síndrome metabólico para cada categoría de IMC, en una extensa muestra de adultos sin diabetes en la base de referencia del Estudio Longitudinal de Salud del Adulto (ELSA-Brasil). Entre los 12.313 participantes con una media de edad de 51,2 años (DE 8,9), la prevalencia de síndrome metabólico fue 34,6%, y un 60,1% sufría sobrepeso u obesidad. La prevalencia de síndrome metabólico entre las categorías: peso normal, sobrepeso y obesidad fueron respectivamente, 13%, 43,2% y 60,7%. El punto de máxima sensibilidad combinada y especificidad de HOMA-IR para discriminar el síndrome metabólico fue 2,35 en toda la muestra, con valores crecientes en las categorías de IMC más altas. Esta investigación contribuye a entender mejor los valores HOMA-IR, asociados con resistencia a la insulina y síndrome metabólico en una gran muestra de adultos brasileños, además del planteamiento de que el uso de puntos de corte según la curva ROC es quizás la mejor estrategia a seguir. También sugiere que valores diferentes pueden ser apropiados a través de las categorías de IMC.

Association between the screen time and the cardiorespiratory fitness with the presence of metabolic risk in schoolchildren / Associação entre o tempo de tela e a aptidão cardiorrespiratória e a presença de risco metabólico em escolares

ABSTRACT Objective: To verify the association between screen time and cardiorespiratory fitness with the presence of metabolic risk in schoolchildren in an isolated and clustered manner. Methods: Cross-sectional study with 1.200 schoolchildren from Santa Cruz do Sul-RS. Screen time and cardiorespiratory fitness were evaluated. The continuous metabolic risk score was calculated by summing the Z score of the waist circumference, systolic blood pressure, glucose, triglycerides, total cholesterol, low-density lipoprotein (LDL-C) and high-density lipoprotein (HDL-C). Results: Children (34.3%) and adolescents (48.2%) had high screen time, while 44.3% of the children and 53.3% of the adolescents were unfit in relation to cardiorespiratory fitness. Regarding the relation of screen time/cardiorespiratory fitness, 14.7% of the children and 26.9% of the adolescents presented high screen time and low levels of cardiorespiratory fitness. The presence of metabolic risk was shown in children (17.1%) and adolescents (14.7%). The presence of metabolic risk was directly associated with low levels of cardiorespiratory fitness in children and adolescents. When analyzed in clusters, the metabolic risk in children was 11% more prevalent in subjects with low screen time/unfit and 12% in subjects with high screen time/unfit, whereas in adolescents, the prevalence of metabolic risk was also higher in those with low screen time/unfit (8%) and high screen time/unfit (7%). Conclusions: The presence of metabolic risk in children and adolescents was associated with low levels of cardiorespiratory fitness, independent of screen time, in an isolated or clustered manner.

RESUMO Objetivo: Verificar a associação entre tempo de tela e aptidão cardiorrespiratória, de forma isolada e agrupada, e a presença de risco metabólico em escolares. Métodos: Estudo transversal com 1.200 escolares de Santa Cruz do Sul (RS). Foram avaliados o tempo de tela e a aptidão cardiorrespiratória. Foi calculado o escore de risco metabólico por meio da soma do escore Z, da circunferência da cintura, da pressão arterial sistólica, da glicose, dos triglicerídeos, do colesterol total, do colesterol da lipoproteína de baixa densidade (LDL) e do colesterol da lipoproteína de alta densidade (HDL). Resultados: Crianças (34,3%) e adolescentes (48,2%) apresentaram elevado tempo de tela, enquanto 44,3% das crianças e 53,3% dos adolescentes foram inaptos no tocante à aptidão cardiorrespiratória. Na relação tempo de tela/aptidão cardiorrespiratória, 14,7% das crianças e 26,9% dos adolescentes exibiram elevado tempo de tela e baixos níveis de aptidão cardiorrespiratória. A presença de risco metabólico foi evidenciada em crianças (17,1%) e em adolescentes (14,7%). A presença de risco metabólico esteve associada diretamente com baixos níveis de aptidão cardiorrespiratória nas crianças e nos adolescentes no que se refere às variáveis de forma isolada. Quando analisado de modo agrupado, o risco metabólico em crianças foi 11% mais prevalente em sujeitos com baixo tempo de tela/inaptos e 12% em sujeitos com elevado tempo de tela/inaptos, enquanto em adolescentes a prevalência de risco metabólico também foi superior nos escolares com baixo tempo de tela/inaptos (8%) e elevado tempo de tela/inaptos (7%). Conclusões: A presença de risco metabólico em crianças e adolescentes esteve associada com baixos níveis de aptidão cardiorrespiratória, independentemente do tempo de tela, tanto de modo isolado quanto agrupado.

Comparison of different criteria in the prevalence of metabolic syndrome in students from paranavaí, paraná / Comparação de diferentes critérios na prevalência de síndrome metabólica em escolares de paranavaí, paraná

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.
