Association between the type of physical activity and metabolic syndrome in middle-aged and older adult residents of a semi-mountainous area in Japan

BACKGROUND@#Physical activity is reported to prevent metabolic syndrome. However, it is unclear whether exercise or daily physical activity is more beneficial for residents of semi-mountainous areas. This study aimed to identify whether daily physical activity is more beneficial than exercise for the prevention of metabolic syndrome among middle-aged and older residents in semi-mountainous areas.@*METHODS@#We analyzed secondary data of 636 people who underwent a specific health checkup in a semi-mountainous area of Japan. Physical activity was classified into four types: inactivity (I-type; without exercise and without daily physical activity), only exercise (E-type; with exercise and without daily physical activity), only daily physical activity (D-type; without exercise and with daily physical activity), and full physical activity type (F-type; with exercise and with daily physical activity). We compared the means of risk factors for metabolic syndrome by these four types, followed by logistic regression analysis, to identify whether and to what extent the D-type was less likely to have metabolic syndrome than the E-type.@*RESULTS@#The prevalence of metabolic syndrome was 28.5% (men 45.7%, women 15.8%). The proportions of men with exercise and daily physical activity were 38.7% and 52.8%, respectively. For women, the proportions were 33.0% and 47.1%, respectively. In women, the D-type had the significantly lowest BMI, smallest waist circumference, highest HDL-C, and lowest prevalence of metabolic syndrome of the four types; the same was not observed in men. Additionally, D-type activity was more strongly associated with a reduced risk of metabolic syndrome than E-type activity in women (adjusted odds ratio 0.24; 95% confidence interval 0.06-0.85, P = 0.028).@*CONCLUSIONS@#Compared to middle-aged and older women residents with exercise in a semi-mountainous area of Japan, those with daily physical activity may effectively prevent metabolic syndrome.

Consideraciones en el manejo del adulto con Hiperplasia Suprarrenal congénita clásica por déficit de 21-Hidroxilasa / Management considerations for the adult with congenital adrenal hyperplasia due 21-hydroxylase deficiency

La Hiperplasia Suprarrenal Congénita (HSRC) corresponde a un grupo de defectos genéticos en la síntesis de cortisol. El 95% de ellas son debidas al déficit de 21-hidroxilasa por lo que nos referiremos solo a esta deficiencia. La hiperplasia suprarrenal congénita clásica (HSRC-C) debuta en recién nacidos o lactantes con insuficiencia suprarrenal primaria, diferentes grados de hiperandrogenismo clínico en mujeres y puede coexistir con hipotensión, hiperkalemia e hiponatremia si hay un déficit clínico de aldosterona. El objetivo de este artículo es actualizar el conocimiento y enfoques sugeridos para el manejo de la HSRC-C desde el inicio de sus controles en la etapa adulta. El diagnóstico diferencial en retrospectiva de la HSRC-C y la no clásica (HSRC-NC) a veces resulta difícil ya que esta enfermedad es un espectro fenotípico continuo. La insuficiencia suprarrenal y la dependencia a terapia corticoidal son los eventos principales para diferenciar estas dos patologías que tienen enfoques terapéuticos diferentes. El tratamiento de la HSRC-C en adultos abarca 2 objetivos primarios: la adecuada sustitución de la falla suprarrenal y el control de hiperandrogenismo mediante el uso de corticoides en sus dosis mínimas efectivas. En la mujer existen terapias complementarias para el control del hiperandrogenismo como anticonceptivos y otras que se encuentran en diferentes fases de investigación. Esto permite disminuir las dosis de corticoides en algunos casos. Es importante a la vez abordar tres objetivos secundarios: controlar el riesgo cardiometabólico propio de la enfermedad, evitar el sobre tratamiento corticoidal y manejar la infertilidad. La correcta monitorización del tratamiento en adultos tomando en cuenta los objetivos descritos permite una mejor calidad de vida en estos pacientes. Finalmente el consejo genético debe realizarse en todos los pacientes con HSRC que deseen fertilidad y en sus parejas. El estudio requiere de secuenciación del gen CYP21A2 y debe realizarse en un laboratorio de experiencia.

Congenital Adrenal Hyperplasia (CAH) are a group of genetic defects characterized by impaired cortisol synthesis. 95% of them are due to 21-hydroxylase deficiency. We will discuss only this enzyme's deficiency. Classic congenital adrenal hyperplasia (CAH-C) debuts in newborns or infants with primary adrenal insufficiency, some degree of clinical hyperandrogenism in newborn females, and can coexist with hypotension, hyperkalemia, and hyponatremia if there is a clinical aldosterone deficiency. The objective of this article is to update the knowledge and suggested approaches for the management of CAH-C from the beginning of its controls in the adult stage. The retrospective differential diagnosis of CAH-C and non-classical (CAH-NC) is sometimes difficult because this disease is a continuous phenotypic spectrum. Adrenal insufficiency and dependence on corticosteroid therapy are the main events to differentiate these two pathologies that have different therapeutic approaches. In adults, the treatment of CAH-C must include 2 primary objectives: adequate the replacement of adrenal failure and control of hyperandrogenism, through the use of corticosteroids in their minimum effective doses. In women there are complementary therapies for the control of hyperandrogenism, such as contraceptives and others that are in different phases of research. This makes it possible to reduce the doses of corticosteroids in some cases. It is important at the same time to address three secondary objectives: control the cardiometabolic risk of the disease secondary to corticosteroid treatment, avoid corticosteroid overtreatment and manage infertility. The correct monitoring of treatment in adults and taking in to account the objectives described, allows a better quality of life in these patients. Finally, genetic counseling must be carried out in all patients planning for children, with any type of CAH and in their partners. The study requires sequencing of the CYP21A2 gene and must be performed in a certified laboratory.

Associations between new and old anthropometric indices with type 2 diabetes mellitus and risk of metabolic complications: a cross-sectional analytical study / Associação de índices antropométricos novos e antigos com diabetes melito tipo 2 e risco de complicações metabólicas: um estudo analítico de corte transversal

Abstract Background Obesity can increase the risk of diabetes mellitus and complications associated with it. Objectives The aim of this study was to estimate the associations between new and old anthropometric indices and the risk of type 2 diabetes mellitus (T2DM) and its metabolic complications. Methods In this cross-sectional analytical study, 110 T2DM subjects and 110 healthy controls were selected by convenience sampling. Metabolic factors were evaluated including the atherogenic index of plasma (AIP), glycemic status, lipid profile, blood pressure, kidney indices, new anthropometric indices (abdominal volume index [AVI], body shape index [ABSI], lipid accumulation product [LAP], body adiposity index [BAI], and conicity index [CI]), and old anthropometric indices (weight, body mass index [BMI], and waist and hip circumference [WC and HC]). Results Significant positive correlations were observed between AVI, LAP, and BAI and fasting blood glucose and HbA1c in the T2DM group (p < 0.001 for all associations). The odds ratio (OR) for T2DM elevated significantly with increasing BMI (OR: 1.30, 95% CI: 1.20-1.42), LAP (OR: 1.20, 95% CI: 1.13-1.27), and BAI (OR: 1.32, 95% CI: 1.21-1.43). The indices AVI (OR: 1.90, 95% CI: 1.57-2.29), LAP (OR: 1.19, 95% CI: 1.13-1.27), BAI (OR: 1.19, 95% CI: 1.12-1.26), WC (OR: 1.29, 95% CI: 1.18, 1.42), and HC (OR: 1.07, 95% CI: 1.01, 1.14) significantly increased the risk of metabolic syndrome (MetS). Conclusions Associations were identified between obesity indices and diabetes. These indices could be used in clinical practice for evaluation and control of T2DM.

Resumo Contexto A obesidade pode aumentar o risco de diabetes melito e complicações associadas. Objetivos O objetivo deste estudo foi estimar a associação de índices antropométricos novos e antigos com o risco de diabetes melito tipo 2 (DM2) e suas complicações metabólicas. Métodos Neste estudo analítico transversal, 110 indivíduos com DM2 e 110 controles saudáveis foram selecionados por amostragem de conveniência. Foram avaliados os fatores metabólicos, incluindo índice aterogênico plasmático, estado glicêmico, perfil lipídico, pressão arterial, índices renais, índices antropométricos novos [índice de volume abdominal (AVI), índice de formato corporal (ABSI), produto de acumulação lipídica (LAP), índice de adiposidade corporal (BAI) e índice de conicidade (CI)] e índices antropométricos antigos [peso, índice de massa corporal (IMC), circunferência de cintura e quadril]. Resultados Foi observada uma correlação positiva significativa de AVI, LAP e BAI com glicemia de jejum e hemoglobina glicada no grupo DM2 (p para todos < 0,001). A odds ratio (OR) do grupo DM2 foi significativamente elevada com aumento de IMC [OR: 1,30, intervalo de confiança (IC) de 95%: 1,20-1,42], LAP (OR: 1,20, IC95%: 1,13-1,27) e BAI (OR: 1,32, IC95%: 1,21-1,43). Os índices AVI (OR: 1,90, IC95%: 1,57-2,29), LAP (OR: 1,19, IC95%: 1,13-1,27), BAI (OR: 1,19, IC95%: 1,12-1,26), WC (OR: 1,29, IC95%: 1,18-1,42) e HC (OR: 1,07, IC95%: 1,01-1,14) aumentaram significativamente o risco de síndrome metabólica. Conclusões Foi reconhecida uma associação entre índices de obesidade e diabetes. Esses índices podem ser usados na prática clínica para avaliação e controle do DM2.

La Tomasa reduce parámetros metabólicos e inflamatorios asociados a síndrome metabólico en un modelo murino / Tomasa reduces metabolic and inflammatory parameters associated with metabolic syndrome in a murine model

In our country, cardiovascular diseases (CVD) are the main cause of death. Unhealthy eating habits and sedentary lifestyles, among other factors, have contributed to increase the risk for CDV in the population. An alternative to the commonly used pharmacological therapies is the use of validated natural products that can be incorporated in the development of functional foods or supplements. In particular, the tomato has been shown to have a protective role in CVD; its high content of antioxidants, particularly lycopene, provides it with extensively documented beneficial properties. Tomasa, a by-product of the agroindustry, maintains some of the beneficial characteristics of its fruit of origin. Mice fed with a high-fat (hypercaloric) diet increase their body weight and visceral adipose mass, and also display an increase in metabolic and inflammatory parameters. Our results allow us to conclude that the consumption of Tomasa in mice fed a hypercaloric diet reduces the blood levels of cholesterol, glycaemia and pro-inflammatory cytokines. These results support the rationale of using of this by-product in the generation of functional ingredients with proven beneficial effects.

Dietary Fat Intake and its Association with Adiposity and Inflammatory Markers in Individuals at Cardiometabolic Risk

Abstract Background Fatty acids are important components of diet that may influence the development of CVD. Objective To verify the relationship of dietary fatty acids with cardiometabolic markers in individuals at the cardiometabolic risk. Methods This cross-sectional study involved 282 subjects (116 M/166 F, 42 ± 16 years) attended the Cardiovascular Health Care Program, Universidade Federal de Viçosa (Brazil). Anthropometric and body composition measurements as well as metabolic and inflammatory markers were assessed by standard procedures. Demographic and lifestyle variables were obtained by semi-structured questionnaire. Food consumption was evaluated by 24h recall. Student's t-test or Mann-Whitney-U test and chi-square test were used, considering the statistical significance level of 5% probability. Results Individuals who eaten fat, fatty acids saturated and fatty acids polyunsaturated above recommendation (> 35, 7%, and 10% of caloric intake) were more likely to be overweight (p < 0.05). Those individuals with higher intake of medium-chain fatty saturated acids (≥ 1.05 g/d) had lower values (p < 0.05) of body mass index, waist circumference, waist-hip ratio and waist-height ratio and higher values (p < 0.05) of total leukocytes, C-reactive protein and total cholesterol, and LDL. Subjects with higher of palmitoleic acid intake (≥ 0.94 g/d) presented higher values of BMI, fat percentage and HOMA-IR (p < 0.05). Conclusion This cross-sectional study found different associations of dietary fat and cardiometabolic risk related to adiposity and inflammatory markers, according with chain-size and saturation, indicating the need the more detailed on the dietary assessment of obese patients to identify risk factors and established best strategies to control.

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.

Calcularam-se a fração atribuível (FA) e a fração atribuível proporcional (FAP) e determinou-se a magnitude das desigualdades por meio do índice absoluto de desigualdade e pelo índice relativo de desigualdade. Resultados: A prevalência de SM foi de 40,1%, e 23,3% dos idosos apresentavam pelo menos um componente da síndrome. A chance de SM foi maior entre os idosos fisicamente inativos. Idosos menos escolarizados apresentaram prevalências de SM significativamente maiores em termos absolutos e relativos. As FA e FAP entre os inativos e na população foram significativos. Conclusão: Este estudo demonstrou que a prática de atividade física e a escolaridade são fatores significativamente associados à SM, reforçando a importância desses fatores para o controle dessa síndrome.

ABSTRACT: Objective: Evaluate the association between Metabolic Syndrome (MetS), physical activity and socioeconomic conditions among non-institutionalized elderly individuals. Methodology: Cross-sectional study with, elderly individuals (≥ 60) living in the city of São Paulo. MetS was evaluated by means of the National Cholesterol Education Program criteria, the Adult Treatment Panel III. Descriptive and bivariate analyses were performed, followed by multiple logistic regression with a 5% significance level. An attributable fraction (AF) and a proportional attributable fraction (PAF) were calculated in relation to physical activity. The magnitude of the socioeconomic inequalities was evaluated using the Slope Index of Inequality (SII) and the Relative Index of Inequality (RII). Results: The prevalence of MetS was 40.1%, and 23.3% of the individuals had at least one MetS' component. Physically inactive elderly had higher chances of having MetS. The prevalence of MetS was higher among those with lower education levels in both absolute and relative terms. AF and PAF were significant among the inactive individuals and for the total population. Conclusion: This study demonstrated that physical activity and schooling are significantly associated with MetS, highlighting the importance of these factors for the control of this syndrome.

Prevalence of insulin resistance and association with metabolic risk factors and food consumption in adolescents - recife/brazil / Prevalência de resistência à insulina e associação com fatores de risco metabólicos e consumo alimentar de adolescentes - recife/brasil

ABSTRACT Objective: To identify the prevalence of insulin resistance in adolescents and its associations with metabolic factors and food intake. Methods: Cross-sectional study conducted with a stratified, complex, school-based sample. The subjects were adolescents (n=1,081) who participated in the Study of Cardiovascular Risk in Adolescents in the city of Recife (Pernambuco, Brazil). We analyzed demographic, socioeconomic, behavioral, anthropometric, biochemical, and dietary variables. Insulin resistance was defined as HOMA-IR>75th percentile. A Poisson multivariate regression model with robust variance adjustment was used, and variables with p≤0.05 in the final model were considered statistically associated with insulin resistance. Results: Median age was 14 years (interquartile range: 13-16 years), and 25.3% of the sample showed insulin resistance. The variables associated with insulin resistance in the final model were age, body mass index-for-age (BMI/A), biochemical markers (triglycerides and high-density lipoprotein cholesterol) and saturated fat intake, with insulin resistance being more prevalent in individuals whose consumption of this type of fat was below the median of the sample distribution. Conclusions: Insulin resistance was prevalent in the adolescents analyzed and was significantly associated with metabolic variables and saturated fat intake.

RESUMO Objetivo: Identificar a prevalência de resistência à insulina em adolescentes e verificar sua associação com variáveis metabólicas e com o consumo alimentar.

ABSTRACT Introduction: the prevalence of the metabolic syndrome is very high around the world and is still vertiginously increasing in the last years. Therefore, it can be considered a pandemic of the current times. It is thought that 25 % of the adult population suffers it. Objective: to determine the prevalence of the metabolic syndrome and to identify other clinical forms of the atherosclerotic vascular disease in elder people who entered the Service of Geriatrics of the Provincial Teaching Clinical Surgical Hospital "Celia Sanchez Manduley", of Manzanillo, Granma, in the period from June 2015 to June 2016. Materials and methods: a cross-sectional, observational, descriptive study was carried out with the inclusion of the 120 elder people who the Service of Geriatrics. Results: 105 individuals of 129 studied were diagnosed with metabolic syndrome. The 79-79 age group and male sex were the most affected by endocrinopathy. Other clinical forms of the arteriosclerotic vascular disease identified in the studied elder people were ischemic heart disease, cerebrovascular disease and hypertensive heart disease. Conclusions: there is a high prevalence of the metabolic syndrome among the studied elder people.

Validation of a non-laboratorial questionnaire to identify Metabolic Syndrome among a population in central Mexico / Validación de un cuestionario en el que no se recurre al diagnóstico de laboratorio para detectar el síndrome metabólico en una población de la zona central de México / Validação de um instrumento de coleta de dados não laboratoriais para identificar síndrome metabólica em uma população da região central do México

ABSTRACT Objective To determine the reliability of a non-laboratorial questionnaire, the Encuesta de Identificación de Sujetos Metabólicamente Comprometidos en Fase-I (ESF-I) for identifying Metabolic Syndrome among a population in central Mexico. Methods Clinical and biochemical parameters were collected for 232 participants from 1 June 2012 - 31 August 2013. Three definitions of Metabolic Syndrome (Harmonizing, National Cholesterol Education Program Expert Panel and Adult Treatment Panel III [ATPIII], and International Diabetes Federation [IDF]) were used to allocate subjects to either the normal or Metabolic Syndrome positive (MetS+) group. The predictability of the questionnaire was determined by the Area-Under-the-Receiver-Operating Characteristic curve (AUC). Youden's index was calculated and the highest score was considered the optimal cutoff value. Cohen´s kappa (κ) was calculated to determine the level of agreement between the ESF-I questionnaire (max score: 15 based on 15 items) and Metabolic Syndrome. Results From 53.8% - 60.7% of the participants were determined to be MetS+. The average questionnaire score was significantly higher in the MetS+ group for each definition (4.0 vs. 8.0, P < 0.05). The ESF-I questionnaire was predictive for the Harmonizing definition (AUC = 0.841, 95%CI: 0.790 - 0.892), the ATPIII definition (AUC = 0.827, 95%CI: 0.774 - 0.880), and the IDF definition (AUC = 0.836, 95%CI: 0.785 - 0.887). A cutoff value of 7 was determined for each definition; therefore, the cohort was re-categorized based on questionnaire results. There was a strong agreement between the ESF-I questionnaire and MetS (Harmonizing: accuracy = 77.6%, κ = 0.554; ATPIII: accuracy = 74.1%, κ = 0.489; IDF: accuracy = 74.6%, κ = 0.495, P < 0.001). Conclusion The ESF-I questionnaire can identify MetS+ patients, and therefore, lead to earlier diagnoses, reduced number of consultations, and lower costs with easier application.

RESUMEN Objetivo Determinar la fiabilidad de un cuestionario en el que no se recurre al diagnóstico de laboratorio, la Encuesta de Identificación de Sujetos Metabólicamente Comprometidos en Fase-I (ESF-I), para detectar el síndrome metabólico en una población de la región central de México. Métodos Se recogieron parámetros clínicos y bioquímicos de 232 participantes desde el 1 de junio del 2012 al 31 de agosto del 2013. Se usaron tres definiciones de síndrome metabólico (la unificadora, la del Grupo de Expertos en el Tratamiento de Adultos [ATPIII] del Programa Nacional de Educación sobre el Colesterol y la de la Federación Internacional de la Diabetes [FID]) para asignar los participantes al grupo normal o al grupo de síndrome metabólico positivo (SMet+). Se determinó la previsibilidad del cuestionario con el área bajo la curva de eficacia diagnóstica (curva ROC). Se calculó el índice de Youden y la puntuación más alta se consideró el valor de corte óptimo. El coeficiente (k) de Cohen se calculó para determinar el grade de acuerdo entre el cuestionario ESF-I (máxima puntuación: 15 sobre 15 ítems) y el síndrome metabólico. Resultados Del 53,8 % al 60,7 % de los participantes se asignaron al grupo SMet+. La puntuación promedio del cuestionario fue significativamente mayor en el grupo de SMet+ para cada definición (4,0 vs. 8.0, P < 0.05). El cuestionario ESF-I fue predictivo para la definición unificadora (AUC = 0,841, 95 % CI: 0,790 - 0,892), la definición ATPIII (AUC = 0,827, 95 % CI: 0,774 - 0,880) y la definición de la FID (AUC = 0,836, 95 % CI: 0,785 - 0,887). Se determinó un el valor de corte óptimo de 7 para cada definición; por lo tanto, se reclasificó la cohorte según los resultados del cuestionario. Hubo una gran coincidencia entre el cuestionario ESF-I y SMet (unificadora: exactitud = 77,6 %, κ = 0,554; ATPIII: exactitud = 74,1 %, κ = 0,489; FID: exactitud = 74,6%, κ = 0,495, P < 0,001). Conclusiones El cuestionario ESF-I puede detectar pacientes con SMet+ y, por lo tanto, conducir a diagnósticos más tempranos, reducir la cantidad de consultas y reducir los costos con una aplicación más fácil.

RESUMO Objetivo Determinar a confiabilidade de um instrumento de coleta de dados não laboratoriais, Encuesta de Identificación de Sujetos Metabólicamente Comprometidos en Fase-I (pesquisa de identificação de indivíduos com comprometimento metabólico em fase I, ESF-I) para identificar síndrome metabólica em uma população da região central do México. Métodos Foram coletados parâmetros clínicos e bioquímicos de 232 participantes da pesquisa entre 1° de junho de 2012 e 31 de agosto de 2013. O estudo se baseou em três definições de síndrome metabólica (definição harmonizada do Painel de Especialistas do Programa Nacional de Educação em Colesterol dos Estados Unidos [NCEP]; Painel para Tratamento de Adultos III [ATPIII]; e Federação Internacional de Diabetes [FIL]) para alocar os participantes em um grupo normal ou em um grupo com síndrome metabólica (SM). A previsibilidade do instrumento foi determinada pela área sob a curva ROC (característica de operação do receptor) (AUC). O índice de Youden foi calculado e o escore mais alto foi considerado o valor ideal de corte. O coeficiente kappa de Cohen (κ) foi calculado para determinar o grau de concordância entre o questionário ESF-1 (pontuação máxima de 15 em 15 itens) e a síndrome metabólica. Resultados Foi determinado que 53,8% a 60,7% dos participantes apresentavam SM. A pontuação média no instrumento foi significativamente maior no grupo SM com cada uma das definições usadas (4,0 vs. 8,0, P<0,05). O questionário ESF-I foi preditivo com a definição harmonizada (AUC 0,841; IC 95% 0,790-0,892), com a definição do ATPIII (AUC 0,827; IC 95% 0,774-0,880) e com a definição da FIL (AUC 0,836; IC 95% 0,785-0,887). Um valor de corte de 7 foi determinado para cada definição e a coorte foi recategorizada de acordo com os resultados do instrumento. Foi observada uma forte concordância entre o questionário ESF-I e o grupo SM (harmonizada: precisão = 77,6%, κ = 0,554; ATPIII: precisão = 74,1%, κ = 0,489; FIL: precisão = 74,6%, κ = 0,495, P<0,001). Conclusão O questionário ESF-I é capaz de identificar pacientes com síndrome metabólica, possibilitando o diagnóstico precoce, um número menor de consultas e um custo menor com uma aplicação mais simples.

Physical performance, body composition and metabolic syndrome in military personnel from the brazilian army / Desempenho físico, composição corporal e síndrome metabólica em militares brasileiros / Desempeño físico, composición corporal y síndrome metabólico en militares brasileños

INTRODUCTION: The Brazilian Army (BA) considers Military Physical Training (MPT) essential for the development of physical conditioning and general health, including prevention of chronic noncommunicable diseases (CNCDs), including metabolic syndrome (MS) risk factors. The evaluation of body composition using dual-emission x-ray absorptiometry (DXA) quantifies the visceral fat responsible for several types of disease. OBJECTIVE: To verify the behavior among the body composition, anthropometric, hemodynamic and biochemical variables by means of the physical performance of military personnel with MS (W/MS) and without MS (NO/MS). METHODS: The sample consisted of 41 (38.9 ± 2.3 years, 177.8 ± 6.4 cm, 91.5 ± 11.9 kg) military personnel, with 28 individuals diagnosed as W/MS and 13 individuals as NO/MS. Data collection was divided into three days. An anthropometric assessment was performed on the first day. On the second day, the subjects underwent biochemical tests of MS markers, blood pressure (BP) checks, and DXA examinations. On the third day, a physical assessment was applied according to the requirements of the BA (12-minute run, pushups and pullups). RESULTS: There was a significant difference between W/MS and NO/MS subjects in the variables of HDL-C, Diastolic BP, Systolic BP and Waist Circumference. None of the physical variables presented a significant difference. There was also a significant difference between groups for all body composition and anthropometric variables. CONCLUSION: NO/MS subjects have better mean body composition, BP and anthropometric values than W/MS subjects, which may indicate that they are at less risk of CNCDs. The fact that the military subject is or is not a carrier of MS did not influence the performance of the tests applied. Level of Evidence I; Diagnostic studies - Investigation of a diagnostic test.

INTRODUÇÃO: O Exército Brasileiro (EB) considera o Treinamento Físico Militar (TFM) essencial para desenvolver o condicionamento físico e a saúde geral, inclusive a prevenção de doenças crônicas não transmissíveis (DCNT), considerando os fatores de risco de síndrome metabólica (SM). A avaliação da composição corporal por meio do aparelho de absorciometria por dupla emissão de raios-X (DXA) quantifica a gordura visceral responsável por vários tipos de doenças. OBJETIVO: Verificar o comportamento entre as variáveis composição corporal, antropométricas, hemodinâmicas e bioquímicas por meio do desempenho físico de militares com SM (C/SM) e sem SM (S/SM). MÉTODOS: A amostra foi composta por 41 militares (38,9 ± 2,3 anos, 177,8± 6,4 cm, 91,5 ± 11,9 kg), sendo 28 indivíduos diagnosticados C/SM e 13 S/SM. A coleta de dados foi dividida em três dias. No primeiro dia foi realizada uma avaliação antropométrica. No segundo dia, os indivíduos foram submetidos aos exames bioquímicos dos marcadores de SM, medida da pressão arterial (PA) e exames deDXA. No terceiro dia, realizou-se uma avaliação física conforme as exigências do EB (corrida de 12 minutos, flexão de braço sobre o solo, flexão de braço na barra fixa). RESULTADOS: Constatou-se diferença significativa entre os militares C/SM e S/SM nas variáveis HDL-C, PA diastólica, PA sistólica e circunferência da cintura. Nenhuma variável física apresentou diferença significativa. Verificou-se também diferença significativa entre os grupos para todas as variáveis de composição corporal e antropométricas. CONCLUSÃO: Os militares S/SM têm valores médios de composição corporal, PA e antropométricos melhores que os C/SM, o que pode indicar que têm menor risco de DCNT. O fato de o militar ter ou não SM não influenciou a performance dos testes aplicados. Nível de Evidência I; Tipo de Estudo: Estudos diagnósticos-investigação de um exame para diagnóstico.

INTRODUCCIÓN: El Ejército Brasileño (EB) considera el Entrenamiento Físico Militar (EFM) esencial para desarrollar el condicionamiento físico y la salud general, inclusive la prevención de enfermedades crónicas no transmisibles (ECNT), considerando los factores de riesgo del síndrome metabólico (SM). La evaluación de la composición corporal por medio del aparato de absorciometría por doble emisión de rayos X (DXA) cuantifica la grasa visceral responsable de varios tipos de enfermedades. OBJETIVO: Verificar el comportamiento entre las variables composición corporal, antropométricas, hemodinámicas y bioquímicas por medio del desempeño físico de militares con SM (C/SM) y sin SM (S/SM). MÉTODOS: La muestra fue compuesta por 41 militares (38,9 ± 2,3 años, 177,8 ± 6,4 cm, 91,5 ± 11,9 kg) siendo 28 individuos diagnosticados C/SM y 13 S/SM. La colecta de datos fue dividida en tres días. En el primer día se realizó una evaluación antropométrica. En el segundo día los individuos fueron sometidos a los exámenes bioquímicos de los marcadores de SM, medición de la presión arterial (PA) y exámenes de DXA. En el tercer día se aplicó una evaluación física conforme a las exigencias del EB (carrera de 12 minutos, flexión de brazo sobre el suelo y flexión de brazo en la barra fija). RESULTADOS: Se constató diferencia significativa entre los militares C/SM y S/SM en las variables de HDL-C, PA diastólica, PA sistólica y circunferencia de cintura. Ninguna variable física presentó diferencia significativa. Se verificó también diferencia significativa entre los grupos para todas las variables de composición corporal y antropométricas. CONCLUSIÓN: Los militares S/SM poseen valores promedio de composición corporal, de PA y antropométricos mejores que los C/SM, lo que puede indicar que tienen menor riesgo de ECNT. El hecho de que el militar tenga o no SM no influenció en el desempeño de las pruebas aplicadas. Nivel de evidencia I; Tipo de Estudio: Estudios diagnósticos - Investigación de un examen para diagnóstico.

Prevalence of Metabolic Syndrome and Framingham Risk Score in Apparently Healthy Vegetarian and Omnivorous Men / Prevalência de Síndrome Metabólica e Escore de Risco de Framingham em Homens Vegetarianos e Onívoros Aparentemente Saudáveis

Abstract Background: Recent studies have shown a lower prevalence of metabolic syndrome (MSyn) in vegetarians (VEG) despite the inconclusive evidence from others. Objective: To verify the association between diet and other lifestyle characteristics and the prevalence of MSyn, cardiovascular risk factors (CRF), and Framingham Risk Score (FRS) in apparently healthy VEG and omnivorous (OMN) men. Methods: In this cross-sectional study, 88 apparently healthy men ≥ 35 years, 44 VEG and 44 OMN, were assessed for anthropometric data, blood pressure, blood lipids, glucose, C-reactive protein (CRP) and FRS. To test the association between lifestyle and MSyn, Student t test, chi-square test, and multiple logistic regression model were used. A significance level of 5% was considered in all statistical analyses. Results: Several CRF were significantly lower in VEG than in OMN: body mass index, systolic blood pressure, diastolic blood pressure, fasting serum total cholesterol, LDL-cholesterol, apolipoprotein b, glucose, and glycated hemoglobin (all p < 0.05). The FRS mean was lower in VEG than in OMN (2.98 ± 3.7 vs 4.82 ± 4.8, p = 0.029). The percentage of individuals with MSyn was higher among OMN than among VEG (52.3 vs.15.9%) (p < 0.001). The OMN diet was associated with MSyn (OR: 6.28 95%CI 2.11-18.71) and alterations in most MSyn components in the multiple regression model independently of caloric intake, age and physical activity. Conclusion: The VEG diet was associated with lower CRF, FRS and percentage of individuals with MSyn.

Resumo Fundamento: Estudos recentes mostraram menor prevalência de Síndrome Metabólica (SM) em vegetarianos (VEG), apesar de evidências inconclusivas de outros. Objetivo: Verificar associação entre dieta e características do estilo de vida e a prevalência de SM, fatores de risco cardiovascular (FRCV) e Escore de Framingham (EF) em homens VEG e onívoros (ONI) aparentemente saudáveis. Métodos: Neste estudo transversal, 88 homens aparentemente saudáveis ≥ 35 anos, VEG (n = 44) e ONI (n = 44), foram avaliados quanto a dados antropométricos, pressão arterial, lípides plasmáticos, glicemia, proteína C reativa e EF. Para testar associação entre estilo de vida e SM, o teste t de Student, o teste qui-quadrado e a regressão logística múltipla foram utilizados. Foi considerado nível de significância de 5% em todas as análises estatísticas. Resultados: Os níveis dos FRCV avaliados foram menores nos VEG do que nos ONI: índice de massa corporal, pressão arterial sistólica e diastólica, colesterol total, LDL-colesterol, apolipoproteína b, glicemia e hemoglobina glicada (p < 0,05). O EF foi menor nos VEG do que nos ONI (2,98 ± 3,7 vs. 4,82 ± 4,8; p = 0,029). A porcentagem de indivíduos com SM foi maior entre ONI do que entre VEG (52,3 vs.15,9%) (p < 0,001). A dieta ONI foi associada com a SM (OR: 6,28 IC95% 2,11-18,71) e alterações na maioria dos componentes da SM no modelo de regressão logística múltipla, independentemente de ingestão calórica, idade e atividade física. Conclusão: A dieta VEG foi associada com menores taxas de FRC e menores EF e porcentagem de indivíduos com SM.

Lactancia materna, obesidad y síndrome metabólico en la edad escolar / Breastfeeding, obesity and metabolic syndrome at school age

INTRODUCCIÓN: La lactancia materna (LM) puede ser un factor protector de la obesidad y sus complicaciones metabólicas. OBJETIVO: Determinar la asociación entre el antecedente de amamantamiento y la presencia de obesidad, síndrome metabólico (SM) y resistencia insulínica (RI). PACIENTES Y MÉTODOS: Estudio transversal en 20 escuelas públicas de Santiago, Chile. Se evaluó antropometría, presión arterial, perfil lipídico, glicemia, insulinemia e índice HOMA. Los padres respondieron una encuesta sobre el antecedente de LM. Se definió SM según criterios de Cook y RI como HOMA > percentil 90. RESULTADOS: Se recibieron 3.278 encuestas válidas. La edad promedio fue de 11,4 ± 1 años, siendo 52,3% mujeres. La mayoría (98,2%) recibió LM, con una prevalencia de 15,9% de obesidad versus 18,6% en los que no la recibieron (p = 0,039). Hubo una tendencia no significativa a que SM y sus componentes, excepto RI, fueran más prevalentes en el grupo no amamantado. Los escolares que recibieron LM por 3-6 meses presentaron una menor prevalencia de obesidad y de algunos componentes de SM que los que recibieron menor tiempo o no la recibieron; el efecto fue inverso cuando la LM se prolongó por más de 9 meses. CONCLUSIONES: La prevalencia de obesidad fue mayor en los escolares que no fueron amamantados. Durante el primer semestre, la LM de mayor duración se asoció a menor prevalencia de obesidad y complicaciones metabólicas.

INTRODUCTION: Breastfeeding (BF) can be a protective factor against obesity and its associated metabolic complications. OBJECTIVE: To determine the association between breastfeeding history and present obesity, metabolic syndrome (MS) and insulin resistance (IR). PATIENTS AND METHODS: Cross-sectio nal study in 20 public schools in Santiago, Chile. Anthropometry and blood pressure were assessed. Blood lipids, glucose, insulin and HOMA index were measured in a fast blood sample. Parents answe red a survey on BF. MS was defined according to Cook's criteria and IR as HOMA > 90th percentile. Parents answered a survey about the antecedent of breastfeeding. Chi2 and Fischer tests were used (SSPS). RESULTS: 3,278 surveys were valid. Average age: 11.4 ± 1 years, 52.3% were female. Most of them (98.2%) were breasted, with a 15.9% prevalence of obesity versus 18.6% in the group that was not breastfed (p = 0.039). There was a non-significant trend of higher prevalence in MS and its components (except IR) in the non-breastfed group. The group breastfed from three to six months had a lower prevalence of obesity and MS components than the 0 to 3 months group ; the effect was the opposite when BF lsted longer than nine months. CONCLUSIONS: The prevalence of obesity was higher in children that did not received breastfeeding. A longer breastfeeding time during the first semester of life was associated with lower prevalence of obesity and metabolic complications.

Objective:To determine the cardiovascular risk factors associated with hypertension in patients with systemic lupus erythematous. Material and Methods: A cross-sectional study was conducted. The universe was composed of 193 patients with lupus who were treated in the Rheumatology consultation of the Clinical-Surgical Hospital of Holguín from March 3, 2014 to January 1, 2015. The sample was made up of 81 patients who were randomly selected according to a 95 percent confidence interval, a population size of 193, an estimated proportion of arterial hypertension of 0,20, a precision of a 7 percent, and a design effect of 1. The recommendations of the American College of Rheumatology were followed for the diagnosis of lupus erythematous, and national guidelines were used for the diagnosis of hypertension. Clinical, anthropometric, and laboratory variables were determined. Odds Ratio (OR), and 95 percent (IC95 percent) confidence intervals for risk factors were determined. Results: The risk factors associated with hypertension in patients with lupus erythematous are: age (OR=1,04; IC95 percent:1,01-1,08), age of the lupus onset (OR=1,04; IC95 percent:1,01-1,08), diabetes mellitus (OR=8,50; IC95 percent:1,63-44,33), metabolic syndrome (OR=5,09; IC95 percent:1,87-13,84), hyperuricemia (OR=4,08; IC95 percent:1,07-15,44), and microalbuminuria (OR=19,81; IC95 percent:4,24-92,39). Conclusions:The patients with systemic lupus erythematous presented cardiovascular risk factors associated with hypertension, which are identifiable in the primary health care with variables of relatively easy realization(AU)

Health and nutrition in public and private schools in the city of Recife / Saúde e nutrição em escolas públicas e privadas de Recife

Abstract Objectives: to analyze the implementation of initiatives and environments promoting healthy feeding as well as the practice of physical activity in public and private schools in Recife. Methods: the schools selected in the City of Recife (n=39) are part of the sample in the Study of Cardiovascular Risks in Adolescents (ERICA). The degree of implementation was estimated by means of interviews with the school manager emphasizing the following components: community participation, presence of healthy environments, partnership with the health segment, monitoring of nutritional status and nutrition policies. The variables selected were assigned points whose sum rated them as satisfactory implementation, poor implementation and critical implementation. Results: the promotion of healthy eating as well as the practice of physical activity was satisfactorily implemented in 13.8% of public schools. However, no private schools obtained such rating. Public schools, when compared to private schools, showed themselves to be more structured, concerning the policies and environments promoting healthy eating and school community participation, however, they showed greater fragility regarding the promotion of physical activity practice and nutritional status monitoring. A few schools had satisfactory implementation in the partnership with the health segment. Conclusions: public and private schools have presented barriers which compromise the full implementation of initiatives and environments promoting healthy eating and physical activity practice.

Resumo Objetivos: avaliar a implementação de iniciativas e ambientes promotores da alimen-tação saudável e da prática de atividade física em escolas públicas e privadas de Recife. Métodos: as escolas selecionadas em Recife (n=39) fazem parte da amostra do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA). O grau de implementação foi estimado por meio de entrevistas com o gestor escolar enfatizando os seguintes componentes: participação da comunidade, ambientes saudáveis, parceria com o setor de saúde, monitoramento do estado nutricional e políticas de nutrição. Às variáveis selecionadas foram atribuídos pontos cujo somatório as classificou como implementação satisfatória, implementação insatisfatória e implementação crítica. Resultados: a promoção da alimentação saudável e da prática de atividade física foi implementada de forma satisfatória em 13,8% das escolas públicas. No entanto, nenhuma das escolas privadas obteve tal classificação. As escolas públicas, quando comparadas às escolas privadas, apresentaram - se mais estruturadas quanto às políticas e ambientes promotores da alimentação saudável e à participação da comunidade escolar, mas apresentaram maior fragilidade em relação à promoção da prática de atividade física e monitoramento do estado nutricional. Poucas escolas apresentaram implementação satisfatória na parceria com setor saúde. Conclusões: escolas públicas e privadas apresentaram barreiras que comprometem a implementação plena de iniciativas e ambientes promotores da alimentação saudável e da prática de atividade física.
