RESUMO

OBJECTIVE: To examine the association of arterial hypertension and the hypertriglyceridemic waist phenotype (HWP) and hypertriglyceridemic waist-to-height phenotype (HWHP). METHODOLOGY: This cross-sectional study was conducted with 1422 male rotating shift workers in Brazil. The HWP was defined as having a waist circumference ≥94 cm and serum triglycerides ≥150 mg/dL, whereas the HWHP was determined by having a waist-to-height ratio ≥0.5 and serum triglycerides ≥150 mg/dL. To provide a characterization of the sample, data were presented in both absolute and relative values, and Pearson's chi-square test was employed. To investigate the potential association between arterial hypertension and the presence of HWP or HWHP, multivariate logistic regression was conducted, accounting for sociodemographic, behavioral, and clinical variables. Furthermore, we conducted a stratified multivariate logistic regression analysis, considering the duration of shift work, to assess whether the results remained consistent depending on the length of work experience in shifts. RESULTS: A noteworthy association was observed between arterial hypertension and both HWP and HWHP, with HWHP exhibiting a stronger association with the disease. Furthermore, a positive association between arterial hypertension and these phenotypes was identified in workers with five or more years of shift work. CONCLUSION: We recommend the utilization of HWHP as a screening tool, as it indicates a stronger association with arterial hypertension compared to HWP. Additionally, the duration of time spent working in shifts emerged as a significant factor influencing the presence of these phenotypes.

RESUMO

Rheumatoid arthritis (RA) associates with cardiovascular risk factors (CVRF) such as dyslipidemias and systemic inflammation. Cardiovascular Disease (CVD) is the leading cause of mortality. The hypertriglyceridemic waist phenotype (HTWP) identifies increased CVRF; however, information about HTWP on RA is scarce. OBJECTIVE: To evaluate the association of HTWP with CVRF in RA. MATERIAL AND METHODS: Cross-sectional study. Women (125) with RA were included (ACR, 1987). Anthropometry, bioimpedance, body mass index (BMI), disease activity score 28 (DAS28), and health assessment questionnaire disability index (HAQ-Di) were determined. The lipid profile determination includes the atherogenic index (AI) (TC/HDL) and Framingham Risk Score. HTWP is defined as a waist circumference ≥88 cm and triglycerides ≥ 150 mg/dL. Chi-squared and Student's t-tests were applied for comparisons. RESULTS: HTWP was found in 38 (30.4%) patients. The subgroup with HTWP had a greater frequency of arterial hypertension (AHT) (57.9 vs. 37.9, p = 0.04), Type 2 DM (23.7 vs. 8.0, p= 0.02), BMI (29.7 ± 3.2, vs. 26.8 ± 4.3, p < 0.001), fat mass (39.3 ± 4.8 vs. 34.7 ± 6.8, p < 0.001), and AI (4.7 ± 1.2 vs. 3.7 ± 1.0, p < 0.001). No differences between DAS28 and HAQ-Di were found. HTWP was associated with the presence of MetS and CVR (p < 0.001 and p = 0.012, respectively). CONCLUSION: The HTWP in RA is associated with CVRF, and its potential predictive role should be evaluated in longitudinal studies.

RESUMO

Background: The hypertriglyceridemic waist (HTGW) phenotype is characterized by concomitant increases in waist circumference (WC) and blood triglyceride levels (TG), which has been identified as a predictor of metabolic disorders. This study aimed to analyze associations between food consumption, exercise, and the CD36 gene rs1761667 G>A polymorphism with the HTGW phenotype in adult Mexicans. Methods: This cross-sectional study included a total of 255 participants (both genders, between 18-64 years of age). The HTGW phenotype was defined as WC >88 cm in women, WC >102 cm in men, and TG >150 mg/dL. Body composition was analyzed by electrical bioimpedance. Dietary intakes (macro and micronutrients) were evaluated through a validated 64-item food frequency questionnaire and a 24-h recall. Physical exercise was subjectively recorded asking the participants if they regularly performed some systematic exercise or sport of moderate intensity at least 150-300 minutes a week. Biochemical tests were determined by an automated system. A Taqman real-time assay was used to detect the rs1761667 (G>A) polymorphism of the CD36 gene. A multivariate logistic regression model was performed to analyze the variables potentially associated with the HTGW phenotype (adjusted for age, energy intake, and total fat mass). Results: Overall, 21.6% of the population presented the HTGW phenotype; compared to the HTGW-, also, they were older, had more body fat, higher glucose, cholesterol and insulin levels, and high blood pressure. Female sex (OR=2.92, 95% CI: 1.12-7.60, p=0.028), body mass index (OR=1.19, 95% CI: 1.07-1.32, p=0.001), total cholesterol (OR=1.01, 95% CI:1.00-1.02, p=0.039), daily consumption of sugary drinks (OR=6.94, 95% CI: 1.80-26.8, p=0.005), and the CD36 AG genotype (OR=3.81, 95% CI: 1.08-13.4, p=0.037) were positively associated with the HTGW phenotype, while performing exercise played a protective role (OR=0.23, 95% CI: 0.08-0.62, p=0.004). Overall, the model predicted HTGW phenotype in 47% (R2=0.47, p≤0.001). Conclusion: The CD36 AG genotype, daily consumption of sugary drinks and sedentarism are risk factors for HTGW phenotype in Mexicans.

ABSTRACT Introduction. The hypertriglyceridemic waist has been proposed as a phenotype with a strong association with the metabolic syndrome. The frequency of this phenotype in adolescents from Peru, including Andes population is unknown. Objective. To estimate the frequency of the hypertriglyceridemic waist and its association with metabolic abnormalities and other factors in Peruvian adolescents from an Andean region. Methods. We performed a data secondary analysis through cross-sectional design. We analyzed 397 randomly selected adolescents from two public schools in the Cajamarca city. We defined hypertriglyceridemic waist as the simultaneous presence of increased waist circumference (≥ 90th percentile for age and sex) and serum hypertriglyceridemia (≥110 mg/dL). We estimated the point prevalence of hypertriglyceridemic waist and their 95% confidence interval, we also performed a binary logistic regression analysis to identify associated risks. Results. The phenotype of hypertriglyceridemic waist was 2.01% (95%CI: 0.51 to 3.52). The most frequent component was hypertriglyceridemia with 39.55% (95%CI: 34.61 to 44.48), while increased waist circumference affected 3.02% (95%CI: 1.21 to 4.83). Excess weight was the only variable association with hypertriglyceridemic waist phenotype (adjusted OR: 62.7; 95%CI: 6.7 - 587.9; p<0.001). Conclusions. Two of one hundred adolescents aged 11 to 17 years living in a high Andean region of Peru had the hypertriglyceridemic waist phenotype. This phenotype was associated with excess weight.

RESUMO

Cardiovascular diseases are among the main causes of death in Brazil and worldwide. The literature indicates the hypertriglyceridemic waist phenotype (HTWP) as an accessible alternative for the identification of cardiovascular and metabolic risk. The present study aimed to identify the prevalence and factors associated with HTWP in individuals diagnosed with arterial hypertension (AH) and/or diabetes mellitus type 2 (DM2). A cross-sectional study was conducted with individuals diagnosed with AH and/or DM2. The study data were collected through semi-structured interviews containing socio-demographic information, lifestyle, health care, in addition to anthropometric assessment, blood pressure measurement and biochemical blood tests. The prevalence of HTWP was estimated and bivariate and multivariate logistic regression was used to assess the factors associated with HTWP. Of the 788 individuals analysed, 21⋅5 % had the HTWP. In the adjusted model, the following variables remained associated with a greater chance of presenting HTWP: sex, age, body mass index (BMI) and very-low-density lipoprotein (VLDL). Being female increased the chance of HTWP by 7⋅7 times (OR 7⋅7; 95 % CI 3⋅9, 15⋅2). The one-year increase in age increased the chance of HTWP by 4 % (OR 1⋅04; 95 % CI 1⋅02, 1⋅06). The addition of 1 mg/dl of VLDL-c increased the chance of HTWP by 15 % (odds ratio (OR) 1⋅15; 95 % confidence interval (CI) 1⋅12, 1⋅18), as well as the increase of 1 kg/m2 in the BMI increased the chance of this condition by 20 % (OR 1⋅20; 95 % CI 1⋅15, 1⋅27). The prevalence of HTWP was associated with females, older age, higher BMI, higher VLDL-c and risk waist/height ratio.

RESUMO

Introducción: El síndrome de ovario poliquístico se asocia con frecuencia a alteraciones cardiometabólicas; y su asociación con el fenotipo hipertrigliceridemia-obesidad abdominal ha sido poco estudiada en Cuba. Objetivo: Identificar la frecuencia del fenotipo hipertrigliceridemia-obesidad abdominal en mujeres de edad mediana con síndrome de ovario poliquístico y su asociación con la resistencia a la insulina, trastornos del metabolismo de la glucosa y ateroesclerosis subclínica. Método: Estudio descriptivo, transversal, en 30 mujeres. Se tomaron variables clínicas: edad, peso, talla, índice de masa corporal, circunferencia de cintura y cadera, índice cintura/cadera, tensión arterial, además de concentraciones de glucosa, insulina, colesterol total, triglicéridos, HDL-c y LDL-c, e índice HOMA-IR. La aterosclerosis subclínica se evaluó por doppler carotideo y ecocardiograma (hipertrofia ventricular izquierda y grasa epicárdica). El fenotipo hipertrigliceridemia-obesidad abdominal se definió como triglicéridos elevados (≥ 1,7 mmol/L) y circunferencia de la cintura ≥ 80 cm. Resultados: La frecuencia del fenotipo hipertrigliceridemia-obesidad abdominal fue 43,3 por ciento (13/30). Los valores medios de circunferencia abdominal, tensión arterial, así como de glucemia (p < 0,003), insulinemia (p = 0,028), triglicéridos (p < 0,0001), e índice HOMA-IR (p = 0,012) fueron más elevados en el grupo de mujeres con esa condición. A pesar de no haber diferencias significativas la frecuencia de mujeres con incremento del grosor íntima-media carotídeo y de grasa epicárdica fue superior en aquellas con el fenotipo. Conclusiones: La presencia del fenotipo hipertrigliceridemia-obesidad abdominal es frecuente en mujeres con síndrome de ovario poliquístico, y se asocia con alteraciones del metabolismo de la glucosa y la resistencia a la insulina. Este pudiera ser utilizado en la práctica clínica como un marcador de riesgo para alteraciones cardiometabólicas(AU)

Introduction: The polycystic ovary syndrome is frequently associated to cardiometabolic alterations; and its relation with the hypertriglyceridemic waist phenotype has been poorly studied in Cuba. Objective: Identify the frequency of the hypertriglyceridemic waist phenotype in middle age women with polycystic ovary syndrome and its association with insulin resistance, disorders in the glucose metabolism and subclinical atherosclerosis. Methods: Descriptive, cross-sectional study in 30 women. As clinical variables there were used: age, weight, size, body mass index, waist-hip circumference, waist/hip index, blood pressure; glucose, insulin, total cholesterol, triglycerides, HDL-c and LDL-c concentrations, and HOMA-IR index. Subclinical atherosclerosis was assessed by a carotid doppler and an echocardiogram (left ventricular hypertrophy and epicardial fat). The hypertriglyceridemic waist phenotype was defined as high triglycerides levels (≥ 1.7 mmol/L) and CC ≥ 80 cm. Results: The frequency of the hypertriglyceridemic waist phenotype was 43.3 percent (13/30). The mean values of abdominal circumference, blood pressure, as well as glycemia (p < 0.003), insulinaemia (p = 0.028), triglycerides (p < 0.0001), and HOMA-IR index (p = 0.012) were higher in the group of women with that condition. Although there were not significant differences, the frequency of women with increase of the carotid intima-media thickness and epicardical fat was higher in those with the phenotype. Conclusions: The presence of the hypertriglyceridemic waist phenotype is frequent in women with the polycystic ovary syndrome, and it is associated with alterations of the glucose metabolism and insulin resistance. This can be used in the clinical practice as a marker of risk for cardiometabolic alterations(AU)

RESUMO

BACKGROUND: Prevalence of cardiometabolic risk factors is increasing and vitamin D insufficiency/deficiency has become a worldwide public health problem, even in tropical countries. Therefore, we identified the prevalence of hypertriglyceridemic waist phenotype (HWP) and evaluate its relationship with vitamin D insufficiency/deficiency. METHODS: A cross-sectional study with 378 children aged 8 and 9 enrolled in all urban schools in the city of Viçosa, MG, Brazil. Anthropometric measurements, body composition (dual energy X-ray absorptiometry), biochemical tests and clinical evaluation were performed. Poisson regression was used to analyze the association between vitamin D and HWP. RESULTS: Prevalence of HWP was 16.4%. This prevalence was higher among children with vitamin D insufficiency and deficiency and in those with a greater number of other cardiometabolic risk factors. Multiple regression analysis showed that children with vitamin D insufficiency and deficiency had, respectively, prevalence 85% (95% CI: 1.03-3.30) and 121% (95% CI: 1.11-4.45) higher of HWP than the vitamin D sufficiency group. CONCLUSION: Vitamin D insuffiency and deficiency were associated with a higher prevalence of HWP among children, regardless of the presence of other cardiometabolic risk factors, indicating an additional risk of inadequate vitamin D status to cardiometabolic health in childhood.

RESUMO

ABSTRACT Objective: To assess the frequency of the hypertriglyceridemic waist phenotype and its associated factors in children and adolescents with type 1 diabetes mellitus. Methods: This is an observational analytical study with individuals with type 1 diabetes mellitus, aged 5 to 18 years, of both genders, followed in a university hospital in the Brazilian Northeast. Weight, height, and waist circumference were measured, and the lipid profile and glycated hemoglobin were analyzed. The hypertriglyceridemic waist phenotype was defined by the simultaneous presence of increased waist circumference (≥90th percentile for age and gender) and elevated serum triglyceride levels (≥75 mg/dL for children and ≥90 mg/dL for adolescents). We also investigated the family history of cardiovascular diseases and diabetes, as well as sociodemographic and behavioral variables. In the statistical inference tests, the proportions were compared by Pearson's chi-square test ­and/­or Fisher's exact test, being significant p<0.05. Results: A total of 102 patients were evaluated, most of them females (54.9%) and adolescents (66.7%). The frequency of hypertriglyceridemic waist was 23.5%, which was associated with females (p=0.043), overweight (p=0.023), hypercholesterolemia (p=0.002), high LDL (p=0.001), and borderline VLDL (<0.001). Conclusions: The frequency of the hypertriglyceridemic waist phenotype was associated with females, atherogenic lipid profile, and overweight, indicating the importance of the nutritional monitoring of this population, aiming at reducing future cardiovascular diseases.

RESUMO

An appropriate and precise identification of high-risk individuals to develop cardiovascular diseases (CVD) is of high importance to reduce these kinds of diseases, a major health concern worldwide. Therefore, the aim of this research was to evaluate prognostic CVD biomarkers in Mexican women exposed to inorganic arsenic via drinking water. Then, a cross-sectional study including 190 women was achieved. Urinary arsenic (UAs) levels were analyzed as exposure biomarker to that metalloid. While, plasma asymmetric dimethylarginine (ADMA), adipocyte fatty acid-binding protein (FABP4), adiponectin, and chemerin levels, hypertriglyceridemic waist (HW) phenotype, atherogenic index of plasma (AIP), and Framingham risk score (FRS) were assessed as prognostic CVD biomarkers. Mean UAs level detected in the evaluated urinary samples was 45.0 ±â€¯40.0 µg/g creatinine. In addition, mean plasma ADMA, FABP4, chemerin and adiponectin levels were 0.68 µmol/L, 20.3 ng/mL, 12.5 µg/mL, and 255 ng/mL, correspondingly. Approximately, 54% of women participants displayed an HW phenotype. Regarding AIP and FRS values, 0.12 ±â€¯0.15 and 7.50 ±â€¯8.00 were found, respectively. Besides, strong and significant associations (p < 0.05) between UAs and AIP, ADMA, and FABP4 were distinguished. Also, after a multivariate analysis, the association between those variables persisted after adjustment for traditional risk factors of CVD. In conclusion, according to the results found in this research, the most sensible CVD biomarkers distinguished in this study were AIP, ADMA, and FABP4. Nevertheless, more studies are necessary to confirm the results found in this investigation.

RESUMO

Abstract To identify the prevalence and factors associated with hypertriglyceridemic waist (HW) in community-dwelling elderly people in northeast Brazil. Population-based cross-sectional study. Some 316 elderly (≥ 60 years) people of both sexes participated in this study. Data were collected using a questionnaire, based on that used in the Health, Welfare and Aging Study (SABE), in addition to blood tests, blood pressure measurements and anthropometric measurements. The hypertriglyceridemic waist condition was diagnosed using high values of triglycerides (≥ 150 mg/dl) and waist circumference increased ≥ 88 and ≥ 102 cm for women and men, respectively. Logistic regression analysis was used to compare the hypertriglyceridemic waist and associated factors, significance level of 5%. The prevalence of hypertriglyceridemic waist (HW) was 27.1%. The logistic regression model (OR) adjusted showed the condition of HW associated to the feminine sex (OR 4.19), to the insufficiently active elderly (OR 2.41) and with overweight (OR 4.06). A high prevalence (27.1%) of hypertriglyceridemic waist was observed, indicating the female sex, physical inactivity and overweight as key factors associated with hypertriglyceridemic waist in community-dwelling elderly people.

Resumo Identificar a prevalência e os fatores associados à cintura hipertrigliceridêmica em idosos residentes em uma comunidade no nordeste do Brasil. Estudo populacional com delineamento transversal. Participaram do estudo 316 idosos com idade ≥ 60 anos, de ambos os sexos. Os dados foram coletados por meio de um formulário próprio, baseado no questionário usado na Pesquisa Saúde, Bem-Estar e Envelhecimento, além dos exames sanguíneos, aferição da pressão arterial e medidas antropométricas. A cintura hipertrigliceridêmica (CH) foi diagnosticada quando os níveis de triglicerídeos apresentaram valores (≥ 150 mg/dl) e a circunferência da cintura ≥ 88cm para as mulheres e 102 para os homens. Para identificar os fatores associados a CH foi utilizado a análise de regressão logística, com nível de significância 5%. A prevalência de cintura hipertrigliceridêmica foi 27,1%. O modelo de regressão logística (OR) ajustado mostrou a condição de CH associada ao sexo feminino (OR 4.19), aos idosos insuficientemente ativos (OR 2.41) e com sobrepeso (OR 4.06). Foi observada uma alta prevalência de cintura hipertrigliceridêmica em idosos residentes em comunidade, apontando o sexo feminino, a inatividade física e o sobrepeso/obesidade como fatores associados.

RESUMO

O objetivo deste estudo foi estimar a prevalência do fenótipo cintura hipertrigliceridêmica (FCH) em participantes do Estudo Longitudinal da Saúde do Adulto (ELSA-Brasil), identificar fatores de risco associados e comparar com outros indicadores de risco cardiovascular e metabólico. Trata-se de um estudo transversal com dados da linha de base de uma coorte de servidores públicos. O FCH é definido pela presença simultânea de circunferência da cintura (CC) aumentada (≥ 80cm para mulheres, ≥ 90cm para homens de acordo com a Federação Internacional de Diabetes - IDF; e ≥ 88cm para mulheres, ≥ 102cm para homens de acordo com o Programa Nacional de Educação sobre o Colesterol dos Estados Unidos - NCEP) e hipertrigliceridemia. A associação entre as variáveis independentes e FCH foi testada por meio de modelos de regressão logística multivariada. O FCH foi comparado também com outros indicadores de risco cardiovascular e metabólico por meio de testes de correlação, índice kappa, sensibilidade e especificidade. Após exclusões, foram analisados 12.811 participantes. A prevalência do FCH variou de 24,7% (IDF) a 13,3% (NCEP). FCH foi associado a ter idade mais avançada, ao consumo excessivo de álcool, ser ex-fumante, apresentar HDL baixo, não-HDL alto e PCR aumentado, independente do sexo ou critério de definição. FCH associou-se a indicadores de risco cardiovascular, especialmente à síndrome metabólica. A elevada prevalência de FCH e sua associação com indicadores de risco cardiovascular, especialmente com a síndrome metabólica, apoia sua utilização como ferramenta de triagem de risco cardiometabólico na prática clínica.

This study's objectives were to estimate the prevalence of hypertriglyceridemic waist (HTW) phenotype in participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), identify associated risk factors, and compare with other cardiovascular and metabolic risk indicators. This was a cross-sectional study with baseline data from a cohort of public employees. HTW is defined as the simultaneous presence of increased waist circumference (WC) (≥ 80cm for women, ≥ 90cm for men according to the International Diabetes Federation - IDF; and ≥ 88cm for women, ≥ 102cm for men according to the U.S. National Cholesterol Education Program - NCEP) and hypertriglyceridemia. Associations between independent variables and HTW were tested with multivariate logistic regression models. HTW was also compared to other cardiovascular and metabolic risk indicators by means of correlation tests, kappa index, sensitivity, and specificity. After exclusions, 12,811 participants were analyzed. Prevalence of HTW ranged from 24.7% (IDF) to 13.3% (NCEP). HTW was associated with age, excessive alcohol consumption, former smoking, low HDL, non-high HDL, and increased C-reactive protein, independently of gender or the criterion used to define HTW. HTW was associated with cardiovascular risk indicators, especially metabolic syndrome. The high prevalence of HTW and its association with cardiovascular risk indicators, especially metabolic syndrome, supports its use as a cardiometabolic risk screening tool in clinical practice.

El objetivo de este estudio fue estimar la prevalencia del fenotipo cintura hipertrigliceridémica (FCH), en participantes del Estudio Longitudinal de la Salud del Adulto (ELSA-Brasil), identificar factores de riesgo asociados, y compararlo con otros indicadores de riesgo cardiovascular y metabólico. Se trata de un estudio transversal con datos de la línea de referencia de una cohorte de empleados públicos. El FCH se define por la presencia simultánea de circunferencia de la cintura (CC) aumentada (≥ 80cm para mujeres, ≥ 90cm para hombres de acuerdo con la Federación Internacional de Diabetes - IDF; y ≥ 88cm para mujeres, ≥ 102cm para hombres de acuerdo con el Programa National de Educación sobre el colesterol de los EE.UU. - NCEP) e hipertrigliceridemia. La asociación entre las variables independientes y FCH fue probada mediante modelos de regresión logística multivariada. El FCH se comparó también con otros indicadores de riesgo cardiovascular y metabólico, mediante pruebas de correlación, índice kappa, sensibilidad y especificidad. Tras las exclusiones, se analizaron a 12.811 participantes. La prevalencia del FCH varió de un 24,7% (IDF) a un 13,3% (NCEP). El FCH se asoció a tener una edad más avanzada, al consumo excesivo de alcohol, ser ex-fumador, presentar HDL bajo, no-HDL alto y PCR aumentado, independiente del sexo o criterio de definición. FCH se asoció a indicadores de riesgo cardiovascular, especialmente al síndrome metabólico. La elevada prevalencia de FHC y su asociación con indicadores de riesgo cardiovascular, especialmente con el síndrome metabólico, apoya su utilización como herramienta de clasificación de riesgo cardiometabólico en la práctica clínica.

RESUMO

Abstract Background: The hypertriglyceridemic waist (HTW) phenotype is defined as the simultaneous presence of increased waist circumference (WC) and serum triglycerides (TG) levels and it has been associated with cardiometabolic risk in children and adolescents. Objective: The objective was to evaluate the influence of HTW phenotype in the fasting glycemia and blood pressure in children and adolescents over one-year follow-up period. Methods: It is a cohort study involving 492 children and adolescents from 7 to 15 years old, both genders, who were submitted to anthropometric, biochemical and clinical evaluation at the baseline, and also after 6 and 12 months of follow-up. Generalized Estimating Equation (GEE) models were calculated to evaluate the longitudinal influence of the HTW phenotype in the glycemia and blood pressure over one-year. Results: It was observed a prevalence of 10.6% (n = 52) of HTW phenotype in the students. The GEE models identified that students with HTW phenotype had an increase of 3.87 mg/dl in the fasting glycemia mean (CI: 1.68-6.05) and of 3.67mmHg in the systolic blood pressure (SBP) mean (CI: 1.55-6.08) over one-year follow-up, after adjusting for confounding variables. Conclusions: The results of this study suggest that HTW phenotype is a risk factor for longitudinal changes in glycemia and SBP in children and adolescents over one-year follow-up period.

Resumo Fundamento: O fenótipo de cintura hipertrigliceridêmica (CHT) é definido como a presença simultânea de circunferência de cintura (CC) e níveis séricos de triglicérides (TG) aumentados e tem sido associado com risco cardiometabólico em crianças e adolescentes. Objetivo: Avaliar a influência do fenótipo CHT na glicemia de jejum e na pressão arterial em crianças e adolescentes em um período de acompanhamento de um ano. Métodos: Trata-se de um estudo de coorte envolvendo 492 crianças e adolescentes de 7 a 15 anos de ambos os sexos, que foram submetidos à avaliação antropométrica, bioquímica e clínica no início e também após 6 e 12 meses de seguimento. Os modelos de Equação de Estimulação Generalizada (GEE) foram calculados para avaliar a influência longitudinal do fenótipo CHT na glicemia e na pressão arterial ao longo de um ano. Resultados: Foi observada uma prevalência de 10,6% (n = 52) do fenótipo CHT nos estudantes. Os modelos GEE identificaram que os estudantes com fenótipo CHT apresentaram aumento de 3,87 mg/dl na média de glicemia em jejum (IC: 1,68-6,05) e de 3,67 mmHg na pressão arterial sistólica media (PAS) (IC: 1,55-6,08) depois de um ano de acompanhamento, após ajuste para variáveis de confusão. Conclusões: Os resultados deste estudo sugerem que o fenótipo CHT é um fator de risco para alterações longitudinais da glicemia e da PAS em crianças e adolescentes em um período de um ano de seguimento.

Introduction: Nonalcoholic fatty liver disease and hypertriglyceridemic waist are new markers of atherosclerotic cardiovascular disease. Objectives: To characterize the hypertriglyceridemic waist and nonalcoholic fatty liver disease as cardiometabolic risk factors in hypertensive patients. Methods: A prospective longitudinal study was conducted in 131 patients admitted to Miguel Enríquez Clinical-Surgical Teaching Hospital with a diagnosis of arterial hypertension, from July 2015 to July 2016. The variables included were age, sex, smoking, diabetes, body mass index, hypertriglyceridemic waist, blood glucose, total cholesterol, years of hypertension evolution, poorly-controlled hypertension, and nonalcoholic fatty liver disease. Results: One third of the patients showed hypertriglyceridemic waist and nonalcoholic fatty liver. Hypertensive adults with hypertriglyceridemic waist have a higher probability of obesity, elevated fasting glycaemia, as well as greater lack of control and natural history of hypertension. The hypertriglyceridemic waist shows a close relationship and a good predictive value (sensitivity of 86.1percent and specificity of 84.1percent for the identification of nonalcoholic fatty liver in hypertensive adults. Conclusions: The hypertriglyceridemic waist has a good predictive value for the identification of nonalcoholic fatty liver in hypertensive patients and is related to a greater probability of obesity and dysglycemia(AU)

RESUMO

Abstract Objective This study aims to investigate the role of metabolic syndrome (MetS) and the hypertriglyceridemic-waist (HW) phenotype in determining cardiometabolic risk factors and elevated liver enzymes in a national sample of Iranian pediatric population. Method This nationwide study was conducted in the framework of the third survey of a surveillance program. Students, aged 10-18 years, were recruited from 27 provinces in Iran. The prevalence of cardiometabolic risk factors was compared in students with and without HW and MetS. The association of HW with different cardiometabolic risk factors was determined. Results The mean age of studied population was 14.73 ± 2.41 years. Prevalence of HW and MetS was 3.3% and 4%, respectively. Sixty-nine (71.1%) participants with HW had MetS. The prevalence of obesity, elevated systolic blood pressure, hypercholesterolemia, and elevated alanine aminotransaminase (ALT) was significantly higher in subjects with HW phenotype and MetS than in their peers (p < 0.05). A significant association was observed between HW and elevated levels of cholesterol and ALT, as well as between obesity and low HDL-C (p < 0.05). Conclusions The current findings serve as complementary evidence to previous studies, which have been mainly conducted among adults, suggesting that the HW phenotype is associated with cardiometabolic risk factors, especially with elevated cholesterol and ALT. The authors propose that, in primary care settings and in large epidemiological studies, the measurement of all MetS components can be replaced by studying HW as a screening tool for identifying children at high risk for cardiometabolic disorders.

Resumo Objetivo Investigar o desempenho da síndrome metabólica (SM) e do fenótipo de cintura hipertrigliceridêmica (CH) na determinação de fatores de risco cardiometabólico e enzimas hepáticas elevadas em uma amostra nacional da população pediátrica iraniana. Método Estudo nacional feito na estrutura da terceira pesquisa de um programa de vigilância. Foram recrutados alunos de 10-18 anos de 27 províncias do Irã. A prevalência de fatores de risco cardiometabólico foi comparada em alunos com e sem CH e SM. Foi determinada a associação da CH com diferentes fatores de risco cardiometabólico. Resultados A média de idade da população estudada foi de 14,73 ± 2,41 anos. A prevalência de CH e SM foi de 3,3% e 4%, respectivamente; 69 (71,1%) dos participantes com CH apresentaram SM. A prevalência de obesidade, pressão arterial sistólica elevada, hipercolesterolemia e alanina aminotransferase (ALT) elevada foi significativamente maior em meninos e meninas com fenótipo CH e SM do que em seus outros pares (p < 0,05). A associação de CH foi significativa com elevados níveis de colesterol e ALT, bem como obesidade e HDL-C baixo (p < 0,05). Conclusões Os achados atuais servem de evidência complementar de estudos anteriores, conduzidos principalmente com adultos, e sugerem que o fenótipo CH está associado a fatores de risco cardiometabólico, principalmente com colesterol e ALT altos. Propomos que, em ambientes de cuidados básicos e em grandes estudos epidemiológicas, a medição de todos os componentes de SM possa ser substituída pelo estudo da CH como ferramenta de triagem para identificar crianças com alto risco de apresentarem distúrbios cardiometabólicos.

RESUMO

This study assessed the association of the hypertriglyceridemic waist (HTGW) phenotype with prediabetes and diabetes (DM) in a group of Hispanics. Analysis of a cross-sectional study of 858 adults residing in Puerto Rico that collected data on blood pressure, biochemical, and anthropometric measurements was performed. HTGW phenotype was defined as elevated triglycerides and elevated waist circumference. Prediabetes was defined as a fasting glucose of 100-125 mg/dL and DM as a fasting glucose ≥126 mg/dL or prior diagnosis. Prevalence of HTGW, prediabetes, and DM was 27.9, 38.0, and 21.6 %, respectively. Subjects with the HTGW phenotype had higher adjusted odds of prediabetes (POR 5.55; 95 % CI 3.38-9.13) and DM (POR 7.28; 95 % CI 3.63-14.63) compared to those without the phenotype. The association for prediabetes was stronger for women than among men. HTGW phenotype was strongly associated with prediabetes and DM, reinforcing the need to further assess its performance as a screening tool to identify at-risk individuals for cardiometabolic conditions.

RESUMO

OBJECTIVE: To determine the prevalence of metabolic syndrome (MS) and the hypertriglyceridemic waist phenotype (HW) in a representative adolescent sample; as well as to establish which anthropometric indicator better identifies MS and HW, according to gender and adolescent age. METHODS: This cross sectional study had the participation of 800 adolescents (414 girls) from 10-19 years old. Anthropometric indicators (body mass index, waist perimeter, waist/stature ratio, waist/hip ratio, and central/peripheral skinfolds) were determined by standard protocols. For diagnosis of MS, the criteria proposed by de Ferranti et al. (2004) were used. HW was defined by the simultaneous presence of increased waist perimeter (>75th percentile for age and sex) and high triglycerides (>100 mg/dL). The ability of anthropometric indicators was evaluated by Receiver Operating Characteristic curve. RESULTS: The prevalence of MS was identical to HW (6.4%), without differences between genders and the adolescence phases. The waist perimeter showed higher area under the curve for the diagnosis of MS, except for boys with 17-19 years old, for whom the waist/stature ratio exhibited better performance. For diagnosing HW, waist perimeter also showed higher area under the curve, except for boys in initial and final phases, in which the waist/stature ratio obtained larger area under the curve. The central/peripheral skinfolds had the lowest area under the curve for the presence of both MS and HW phenotype. CONCLUSIONS: The waist perimeter and the waist/stature showed a better performance to identify MS and HW in both genders and in all three phases of adolescence.

OBJETIVO: Determinar a ocorrência de síndrome metabólica (SM) e do fenótipo cintura hipertrigliceridêmica (CH) em amostra de adolescentes e estabelecer qual indicador antropométrico melhor identifica SM e CH, de acordo com gênero e fase da adolescência. MÉTODOS: Estudo transversal com 800 adolescentes (414 meninas) de 10-19 anos. Indicadores antropométricos (índice de massa corporal, perímetro da cintura, relação cintura/estatura, relação cintura/quadril e relação pregas cutâneas centrais/periféricas) foram determinados por protocolos padronizados. Para diagnóstico da SM, foi usada a proposta de Ferranti et al. (2004). A CH foi definida pela presença simultânea de perímetro da cintura aumentado (>75 percentil por idade e sexo) e triglicerídeos elevados (>100 mg/dL). O desempenho dos indicadores antropométricos foi avaliado por meio da curva Receiver Operating Characteristic. RESULTADOS: A prevalência de SM foi idêntica à de CH (6,4%), sem diferenças entre os gêneros e entre as fases da adolescência. O perímetro da cintura apresentou maior área abaixo da curva no diagnóstico da SM, exceto para meninos entre 17-19 anos, para os quais a relação cintura/estatura exibiu melhor desempenho. No diagnóstico da CH, a cintura isolada apresentou maior área abaixo da curva, exceto para os meninos nas fases inicial e final da adolescência, nos quais a relação cintura/estatura obteve maior área. A relação entre as pregas cutâneas apresentou pior desempenho para identificar SM e CH. CONCLUSÕES: O perímetro da cintura e a relação cintura/estatura mostraram o melhor desempenho para identificar SM e CH em ambos os sexos e nas três fases da adolescência.

RESUMO

Antecedentes. La cintura hipertrigliceridémica (CHTG) se asocia con elevado riesgo cardiometabólico en adultos; sin embargo, se dispone de poca información sobre si la misma genera cambios metabólicos adversos en adolescentes con y sin exceso de peso. Objetivo. Evaluar el perfil del riesgo cardiometabólico asociado con la CHTG y su capacidad para predecir factores de este perfil en adolescentes, categorizados según el puntaje Z del índice de masa corporal. Materiales y métodos. Se evaluaron 96 adolescentes (12-17 años) divididos en dos grupos: normopeso y sobrepeso/obesidad. Se determinaron peso, talla, circunferencia de cintura, presión arterial, estadio de maduración sexual y marcadores bioquímicos del riesgo cardiometabólico. Se calculó un índice de riesgo cardiometabólico agrupado. Resultados. La frecuencia de la CHTG fue de 9.8%. El número de casos de esta fue mayor al avanzar la maduración sexual (p<0.001) y en el grupo con exceso de peso (p=0.043). En el grupo total, la CHTG fue capaz de predecir presión arterial elevada (p<0.002), colesterol no-HDL elevado (p<0.012) y riesgo cardiometabólico agrupado elevado (p<0.001). En tanto que en el grupo normopeso, elevó la relación TGL/HDLc (p=0.003) y el índice de riesgo cardiometabólico agrupado (p=0.001). Por último, en el grupo con sobrepeso/obesidad, esta elevó: presión sistólica (p=0.005) y diastólica (p=0.006), colesterol total (p=0.037) y no-HDL (p=0.029), relación colesterol total/HDLc (p=0.032), relación triglicéridos/HDLc (p<0.001) e índice de riesgo cardiometabólico agrupado (p<0.001), independientemente del sexo, edad y estadio de maduración sexual. Conclusiones. La CHTG fue prevalente y se asoció a un perfil metabólico adverso y riesgo cardiometabólico agrupado elevado en adolescentes con y sin exceso de peso, recomendándose su detección en atención primaria.

Background. Hypertriglyceridemic waist phenotype (HW) is associated with high cardiometabolic risk (CMR) in adults; however, there is little information on whether it causes adverse metabolic changes in adolescents with and without excess body weight or not. Objective. To evaluate the profile of CMR associated with HW and its ability to predict CMR factors in adolescents, categorized by body mass index Z-score. Materials and methods. 96 adolescents (aged 12-17) divided into two groups (normal weight and overweight/obesity) were evaluated. Weight, height, waist circumference, blood pressure and biochemical markers of CMR were measured; the stage of sexual maturation was established. Clustered CMR index was calculated. Results. The frequency of HW was 9.8%. The number of cases of HW was higher in the later stages of sexual maturation (p<0.001) and in the overweight/obesity group (p=0.043). In the total group, the HW was able to predict the presence of high blood pressure (p<0.002), high cholesterol non-HDL (p<0.012) and elevated clustered CMR (p<0.001). In the normal weight group, the presence of HW significantly raised the triglycerides/ HDL-cholesterol ratio (p=0.003) and clustered CMR index (p=0.001); in the overweight/obesity group, HW increased systolic (p=0.005) and diastolic (p=0.006) blood pressure, total (p=0.037) and non-HDL (p=0.029) cholesterol, total cholesterol/ HDL-cholesterol ratio (p=0.032), triglycerides/HDL-cholesterol ratio (p<0.001) and the clustered CMR index (p<0.001), regardless of gender, age and stage of sexual maturation. Conclusions. HW was prevalent and associated with an adverse metabolic profile and high clustered CMR in adolescents with and without excess body weight, so its detection is recommended in primary care.
