Abstract Systemic Arterial Hypertension is a multifactorial clinical condition associated with severe outcomes such as stroke and death. One of the main modifiable risk factor for hypertension is an unhealthy diet, often characterized by the consumption of ultraprocessed foods such as sweetened beverages. We aimed to investigate the relationship between the consumption of sweetened beverages, both sugar-sweetened and artificially sweetened, and the prevalence of hypertension in adults. A cross-sectional, household, population-based study with 1,162 adults from two Brazilian cities were carried out. The consumption of food groups and sweetened beverages was obtained by food frequency questionnaire and other data were self-reported. Weight, height, and waist circumference were measured. The association between sweetened beverages consumption and hypertension was analyzed using Poisson regression models, expressed as Prevalence Ratio. The prevalence of hypertension was 16.7%, with no significant difference between genders. The prevalence of consumption of sweetened beverages was 70.3% in men and 54.6% in women, being significantly higher in men. Women who consumed sugar-sweetened and artificially sweetened beverages 6 to 7 days per week had 92% higher prevalence of hypertension compared to those who did not consume or consumed at a lower frequency. Furthermore, women who consumed artificially sweetened beverages at least 1 time per week had 3.36 times higher prevalence of hypertension. The habitual consumption of sweetened beverages may be an important risk factor for hypertension, especially the consumption of diet beverages, which are often marketed as healthier than sugar-sweetened beverages.

Resumen La Hipertensión Arterial Sistémica es una condición clínica multifactorial asociada a resultados graves como el ictus y la muerte. Uno de los principales factores de riesgo modificables de la hipertensión es una dieta poco saludable, a menudo caracterizada por el consumo de alimentos ultraprocesados como las bebidas endulzadas. Nuestro objetivo fue investigar la relación entre el consumo de bebidas endulzadas, tanto azucaradas como edulcoradas artificialmente, y la prevalencia de hipertensión en adultos. Se realizó un estudio transversal, domiciliario y poblacional con 1,162 adultos de dos ciudades brasileñas. El consumo de grupos de alimentos y bebidas endulzadas se obtuvo mediante cuestionario de frecuencia de alimentos y los demás datos fueron autoinformados. Se midieron el peso, la talla y el perímetro de la cintura. La asociación entre el consumo de bebidas endulzadas y la hipertensión se analizó mediante modelos de regresión de Poisson, expresados como Ratio de Prevalencia. La prevalencia de hipertensión fue del 16,7%, sin diferencias significativas entre géneros. La prevalencia de consumo de bebidas endulzadas fue del 70,3% en los hombres y del 54,6% en las mujeres, siendo significativamente mayor en los hombres. Las mujeres que consumían bebidas azucaradas y edulcoradas artificialmente entre 6 y 7 días a la semana tenían 92% mayor prevalencia de hipertensión que las que no consumían o consumían con una frecuencia menor. Además, las mujeres que consumían bebidas edulcoradas al menos 1 vez por semana tenían una prevalencia de hipertensión 3,36 veces mayor. Así pues, el consumo habitual de bebidas endulzadas puede ser un importante factor de riesgo de hipertensión, especialmente el consumo de bebidas dietéticas, que a menudo se comercializan como más saludables que las bebidas azucaradas.

RESUMO Objetivo Avaliar o consumo de alimentos ultraprocessados e associá-lo a indicadores antropométricos em adolescentes, adultos e idosos Métodos Estudo transversal, domiciliar, de base populacional, compreendendo adolescentes de 10-19 anos, adultos de 2059 anos e idosos de 60 anos ou mais, residentes na zona urbana da cidade de Teresina, Piauí. Foram coletados dados demográficos, socioeconômicos, de estilo de vida, consumo alimentar e antropométrico. O teste de análise de variância foi utilizado juntamente com o teste post-hoc de Bonferroni e regressão linear bruta e ajustada com intervalo de confiança de 95% (IC95%). O nível de significância adotado foi de 5%. Resultados Não houve associação significativa entre o consumo de alimentos ultraprocessados e indicadores antropométricos em adultos e idosos, entretanto, entre os adolescentes, os resultados demonstraram uma associação inversa, sinalizando redução dos indicadores antropométricos à medida que se aumenta o consumo de ultraprocessados. Conclusão Não houve associação entre o consumo de alimentos ultraprocessados e indicadores antropométricos em adultos e idosos, entretanto, entre os adolescentes, os resultados demonstraram uma associação inversa, o que incentiva o desenvolvimento de novos estudos, especialmente, longitudinais.

ABSTRACT Objective To evaluate the consumption of ultra-processed foods and associate it with anthropometric indicators in adolescents, adults, and the elderly. Methods Cross-sectional, domiciliary, population-based study, comprising adolescents aged 10-19 years, adults aged 20-59 years, and elderly people aged 60 or older, residents of the urban area of the city of Teresina, Piauí. Demographic, socioeconomic, lifestyle, food consumption, and anthropometric data were collected. The analysis of variance test was used along with the Bonferroni post-hoc test and crude and adjusted linear regression with a 95% confidence interval (95% CI). The level of significance adopted was 5%. Results There was no significant association between the consumption of ultra-processed foods and anthropometric variables in adults and the elderly. However, among adolescents, the results showed an inverse association, thus signaling a reduction in anthropometric indicators as the consumption of ultra-processed foods increases. Conclusion There was no association between the consumption of ultra-processed foods and anthropometric indicators in adults and the elderly; however, among adolescents, the results showed an inverse association, which encourages the development of new studies, especially longitudinal ones.

SUMMARY OBJECTIVE: To verify the association between metabolic syndrome and its components, and intake of antioxidant nutrients in adolescents. METHODS: This is a cross-sectional study of the data of 327 adolescents in a high school in Teresina, Piauí, Brazil, pertaining to their socioeconomic background, anthropometric measurements, dietary intake (selenium; copper; zinc; vitamins A, C, and E), hemodynamics, and biochemical tests. The criteria for diagnosing metabolic syndrome in adolescents were applied. Binary logistic regression was used to verify the association between metabolic syndrome and its components, and intake of antioxidants. The level of significance was established at p<0.05. RESULTS: Prevalence of metabolic syndrome was 7.0%, with a significant association between body mass index and blood pressure. Lower tertiles of copper and vitamins A and E intake were associated with high triglyceride and glycemic levels. The association with vitamins A and E remained after adjustment. CONCLUSIONS: A significant association between lower vitamins A and E intake and metabolic syndrome components (altered triglycerides and glycemic levels) was found. Besides further studies on this issue, the need for health interventions was found, which ensures the appropriate intake of antioxidant nutrients during adolescence.

RESUMO Objetivo Verificar a influência do consumo de alimentos ultraprocessados em índices antropométricos e de aterogenicidade. Métodos Estudo transversal com 327 adolescentes na faixa etária de 14 a 19 anos. Avaliaram-se dados sociodemográficos, antropométricos, bioquímicos e de consumo alimentar. As razões dos índices de aterogenicidade foram calculadas por meio do Índice de Castelli I (Colesterol Total/Lipoproteína de Alta Densidade), Índice de Castelli II (Lipoproteína de Baixa Densidade/Lipoproteína de Alta Densidade) e da estimativa do tamanho da partícula de Lipoproteína de Baixa Densidade (Índice Aterogênico do Plasma=Triglicerídeos/Lipoproteína de Alta Densidade). A regressão logística foi utilizada para a análise bruta e ajustada entre consumo de alimentos ultraprocessados, indicadores antropométricos e índice de aterogenicidade. O nível de significância foi de 5%. Resultados A maioria dos adolescentes que participaram do estudo era do sexo feminino (59,3%). As meninas apresentaram maior consumo de alimentos ultraprocessados (26,6% vs. 20,5%). Do total de participantes, 16,5% estavam com excesso de peso e 65,7% eram de escolas públicas. Adolescentes com valores alterados para o Índice Castelli I e II e para o Índice Aterogênico do Plasma apresentaram valores de peso, Circunferência da Cintura, Circunferência da Cintura/Altura e Índice de Massa Corporal/Idade significantemente superiores. A análise ajustada identificou associação significante (Razão de possibilidades=2,29; Intervalo de confiança 95%:1,23-4,28) entre o elevado consumo de alimentos ultraprocessados e o índice de Castelli II. Conclusão As associações entre os índices aterogênicos com os índices antropométricos e com o consumo de alimentos ultraprocessados ressaltam a influência negativa desses alimentos na saúde cardiovascular de adolescentes.

ABSTRACT Objective To investigate the influence of ultra-processed food consumption on anthropometric and atherogenic indices. Methods A cross-sectional study was conducted with 327 adolescents aged 14 to 19 years. Sociodemographic, anthropometric, biochemical, and food consumption data were evaluated. The ratios of atherogenic indices were calculated using the Castelli I (Total Cholesterol/High Density Lipoprotein Cholesterol), Castelli II (Low Density Lipoprotein Cholesterol/High Density Lipoprotein Cholesterol), and estimated Low Density Lipoprotein Cholesterol particle size (Atherogenic Index of Plasma=Triglycerides/High-Density Lipoprotein Cholesterol) indices. Logistic regression was used for the unadjusted and adjusted analysis between ultra-processed foods consumption, anthropometric, and atherogenic indices. The level of significance was 5%. Results Most participants were female (59.3%). Girls had a higher consumption of ultra-processed foods (26.6% vs. 20.5%). Of the total number of adolescents, 16.5% were overweight and 65.7% were from public schools. Adolescents with altered values for the Castelli I and II Index, and for the Atherogenic Index of Plasma had significantly higher weights, Waist Circumference, Waist Circumference/ Height and Body Mass Index/ Age values. The adjusted analysis identified a significant association (Odds ratio=2.29; 95% Confidence interval: 1.23-4.28) between the high consumption of ultra-processed foods and the Castelli II index. Conclusion The associations between atherogenic indices and anthropometric indices and the consumption of ultra-processed foods highlight the negative influence of these foods on adolescents’ cardiovascular health.

Resumo O objetivo do estudo foi analisar a associação entre o consumo de alimentos ultraprocessados (AUP) e parâmetros lipídicos. Estudo transversal realizado com adolescentes de ensino médio. O consumo alimentar foi analisado por meio de recordatório alimentar de 24h, sendo os AUP identificados de acordo com a NOVA classificação de alimentos. Os níveis de colesterol total, HDL-c e triglicérides, foram determinados por colorimetria enzimática e a fração de LDL-c estimada por fórmula. Utilizou-se o teste t de Student ou Mann-Whitney para comparação de médias e regressão linear para realizar associações entre as variáveis. Os resultados mostram que o consumo de AUP foi mais frequente nas adolescentes do sexo feminino, entre a faixa etária 17 a 19 anos, com renda familiar superior a dois salários mínimos e de escolas particulares. Nota-se que os indivíduos no maior tercil de consumo de AUP apresentaram maior ingestão energética, de carboidratos e de sódio, com menor ingestão de proteínas e de fibras. Observou-se, ainda, que o maior consumo de AUP foi associado negativamente aos níveis de HDL-c e positivamente aos níveis de triglicerídeos e dislipidemia. Portanto, os AUP estão associados a uma piora no perfil nutricional da dieta e alterações negativas nos parâmetros lipídicos de jovens.

Abstract The scope of this study was to analyze the association between ultra-processed food (UPF) consumption and lipid parameters. It was a cross-sectional study performed with high school adolescents. Food consumption was analyzed by means of a 24-hour food recall form, where UPF were identified in line with the NOVA system of food classification. The total cholesterol levels, HDL-c and triglycerides were determined by enzymatic colorimetry and the LDL-c fraction estimated by formula. The Student’s t-test or Mann-Whitney was used to compare averages, and linear regression to make associations among the variables. The results show that UPF consumption was more frequent in female adolescents between 17 and 19 years of age, with a family income above two minimum wages and from private schools. It was observed that individuals in the upper third of UPF consumption had a higher energetic, carbohydrate and sodium intake, with a lower intake of proteins and fibers. Moreover, it was found that a higher UPF intake was negatively associated with HDL-c levels and positively associated with triglyceride levels and dyslipidemia. Therefore, UPF is associated with a worsening of the nutritional profile of the diet and contributes to negative changes in the lipid parameters of young individuals.

Resumo Introdução A síndrome metabólica é uma desordem multifatorial relacionada, principalmente, com a deposição de gordura abdominal e as alterações da homeostase da glicose e/ou resistência à insulina. Estudos demonstram associações entre o excesso de peso na infância e as taxas de morbimortalidade elevadas na vida adulta; portanto, a presença de alterações metabólicas na infância e/ou na adolescência pode contribuir para um perfil de saúde desfavorável ao futuro dos indivíduos. Objetivo Determinar a prevalência de síndrome metabólica e verificar sua associação com estado nutricional em adolescentes. Método Estudo transversal com adolescentes entre 14 e 19 anos de escolas públicas e particulares. Realizou-se avaliação antropométrica, incluindo o índice de massa corporal e o perímetro da cintura, e foram determinados os parâmetros bioquímicos e a pressão arterial. Para o diagnóstico da síndrome metabólica, utilizou-se de critérios da National Cholesterol Education Program’s Adult Treatment Panel III (NCEP/ATP III). As características antropométricas e bioquímicas foram expressas como média e desvios-padrão e comparadas entre os sexos pelo teste t de Student, enquanto, para análise de risco, utilizou-se da regressão logística binária. Resultados Dos 327 adolescentes investigados, 59,9% eram meninas e 65,7% estudavam em escola pública. A prevalência de síndrome metabólica foi de 7%, enquanto a presença de pelo menos um critério diagnóstico da síndrome esteve presente em 90,8% da amostra. Ainda, observou-se associação significativa entre a obesidade e a síndrome metabólica, apontando um maior risco. Conclusão Os adolescentes tiveram uma importante prevalência de síndrome metabólica, apresentando precocemente componentes dessa patologia. Além disso, foi observada associação com a obesidade, evidenciando um maior risco para aqueles que possuem essa condição; portanto, intervenções nutricionais direcionadas à população jovem devem ser promovidas no intuito de melhorar os hábitos alimentares e o estilo de vida.

Abstract Background Metabolic syndrome is a multifactorial disorder mainly related to abdominal fat deposition and changes in glucose homeostasis and / or insulin resistance. Studies show associations between childhood overweight and high morbidity and mortality rates in adulthood, so the presence of metabolic changes in childhood and / or adolescence may contribute to an unfavorable health profile to the future health of individuals. Objective To determine the prevalence of metabolic syndrome and to check its association with nutritional status in adolescents. Method Cross-sectional study with adolescents from public and private schools with ages ranging from 14 to 19 years was carried out. It was performed an anthropometric assessment, including the determination of Body Mass Index and Waist Circumference, besides that the determination of biochemical parameters and blood pressure was also collected. In order to diagnose Metabolic Syndrome, it was used the National Cholesterol Education Program’s Adult Treatment Panel III (NCEP/ATP III) criteria. The anthropometric and biochemical characteristics were expressed as average and standard deviations, and compared between the genders by the Student’s t-test, while for the analysis of risk was used binary logistic regression. Results Of total 327 interviewed adolescents, 59.9% of them were female, 65.7% were studying in public schools. The prevalence of metabolic syndrome was 7%, while the presence of at least one diagnostic criterion of this syndrome was present in 90.8% of the sample. Moreover, obesity was significantly associated with metabolic syndrome, indicating a greater risk. Conclusion Adolescents have a high prevalence of metabolic syndrome, showing early components of this pathology, which is still associated with obesity, highlighting a greater risk for those who present this condition. Therefore, nutritional interventions directed at the young population should be promoted, with the purpose of improving eating habits and lifestyle.

ABSTRACT There is a high prevalence of dyslipidemia in adolescence. The aim of this study was to determine the lipid profile of adolescents and associated factors. We conducted a cross-sectional study with male and female adolescents from public and private schools in Teresina, aged 14 to 19 years. Body mass index (BMI) z-score was obtained and adjusted for age, in addition to waist circumference (WC) percentile values. Lipid profile was determined by enzymatic colorimetric method; LDL-C was calculated. The statistical tests Mann-Whitney U, Student's t, and odds ratio were used. The sample was comprised of 327 adolescents with a mean age of 16.5 years, 59.6% were female and 65.7% from public schools. The prevalence of dyslipidemia was 85.6%, especially hypoalphalipoproteinemia. TG levels were significantly higher and HDL levels were lower among participants who attended public schools (P< 0.05). BMI and WC were associated with dyslipidemia; a higher mean BMI and overweight was observed in girls with dyslipidemia. In the adjusted regression, being from a public school increased the odds for low HDL-C and dyslipidemia, while overall higher BMI and abdominal excess weight represented a risk for higher triglycerides. Thus, overweight increased the chances of hypertriglyceridemia and studying in a public school increased the odds for dyslipidemia and hypoalphalipoproteinemia.

RESUMEN Las dislipidemias tienen una elevada prevalencia en la adolescencia. Nuestro objetivo fue determinar el perfil lipídico de adolescentes y sus factores asociados. Realizamos un estudio transversal que abarcó adolescentes de escuelas públicas y privadas de Teresina, con edad entre 14 y 19 años, de los dos sexos. El índice de masa corporal (escore-z, IMC-Z) se obtuvo conforme a la edad, y la circunferencia de la cintura (CC) en percentil. La determinación del perfil lipídico se realizó por método enzimático colorimétrico; LDL-C fue calculado. Las pruebas estadísticas Mann-Whitney U, T de Student y odds ratio fueran utilizadas. La muestra comprendió 327 adolescentes con edad media de 16,5 años, siendo 59,6% del sexo femenino y el 65,7% de escuelas públicas. La prevalencia de dislipidemia fue 85,6%, destacándose la hipo-alfa-lipoproteinemia. Los niveles de TC fueron significativamente mayores y los de HDL menores en las escuelas públicas (P< 0,05). Al asociar IMC y CC con dislipidemia, se observó mayores valores medios de IMC en las niñas con dislipidemia y sobrepeso. En la regresión ajustada, ser de escuela pública aumentó las posibilidades de bajo HDL-C y dislipidemia, mientras que el exceso de peso global y abdominal fueron factores de riesgo de cambios en los triglicéridos. Así, el exceso de peso elevó las posibilidades de hipertrigliceridemia, y estudiar en escuela pública elevó las posibilidades de dislipidemia e hipo-alfa-lipoproteinemia.

RESUMO Objetivo Analisar a prevalência de síndrome metabólica e sua associação com a qualidade da dieta dos adolescentes. Métodos Pesquisa transversal realizada com 327 adolescentes do ensino médio da rede pública e particular de Teresina, Piauí. Obteve-se dados socioeconômicos, antropométricos, de consumo alimentar, para obtenção do Índicede Qualidade da Dieta Revisado, e relativos à síndrome metabólica (glicemia, pressão arterial, circunferência da cintura, triglicerídeos e colesterol de lipoproteína de alta densidade). As variáveis contínuas foram descritaspor médias, desvios padrão e intervalos de confiança de 95%. Para verificar a associação entre as variáveis dependentes e as explanatórias, calculou-se o odds ratio ajustado. O nível de significância adotado foi de p<0.05. Resultados A prevalência de síndrome metabólica foi 3,3%, sendo a baixa concentração de colesterol de lipoproteína de alta densidade a alteração mais frequente (50,5%). A média de pontuação no Índice de Qualidade da DietaRevisado foi 55,4 pontos. Piores escores foram obtidos em cereais integrais, vegetais verde-escuros e alaranjados, óleos, leites e derivados e frutas integrais. Em contrapartida, os cereais totais, e carnes, ovos e leguminosastiveram pontuações próximas ao máximo estipulado. O menor tercil de vegetais verde-escuros, alaranjados e leguminosas demonstrou risco para baixo colesterol de lipoproteína de alta densidade e o segundo tercil foi protetor para níveis glicêmicos elevados. Quanto ao grupo do leite, seu menor consumo aumentou as chances para níveis elevados de triglicerídeos e de pressão arterial. Conclusão Apesar da baixa prevalência de síndrome metabólica, houve alterações relevantes em seus componentes, associadas ao menor consumo de importantes itens do Índice de Qualidade da Dieta Revisado.

ABSTRACT Objective Analyzing the prevalence of metabolic syndrome and its association with adolescent diet quality. Methods Cross-sectional research with 327 adolescents from public and private high schools of Teresina, Piauí. Socioeconomic, anthropometric, and food consumption data were analyzed to obtain the Brazilian Healthy Eating Index-Revised. Moreover, data related to metabolic syndrome (blood glucose, blood pressure, waist circumference, triglycerides, and high-density lipoprotein cholesterol) were also analyzed. Continuous variables were described by means, standard deviations, and 95% confi dence intervals. To verify the association between dependent and explanatory variables, we calculated the adjusted odds ratio. The level of signifi cance was set at p<0.05. Results The prevalence of metabolic syndrome was 3.3%, with low high-density lipoprotein cholesterol concentration being the most frequent alteration (50.5%). The mean score on the Brazilian Healthy Eating Index-Revised was 55.4 points. The worst scores were obtained in whole cereals, dark-green and orange vegetables, oils, milk and dairy products, and whole fruits. In contrast, total cereals, meat, eggs, and legumes had scores close to the maximum stipulated. The lowest tertile of dark-green, orange, and leguminous vegetables showed risk for low high-density lipoprotein cholesterol, and the second tertile was protective against high blood glucose levels. As for the milk group, its lower intake increased the chances for high triglyceride and blood pressure levels. Conclusion Despite the low prevalence of metabolic syndrome, there were significant alterations in its components,associated with less consumption of important Brazilian Healthy Eating Index-Revised items.

RESUMO Objetivo Esta pesquisa teve como objetivo verificar as associações entre o consumo de nutrientes antioxidantes e as alterações lipídicas e o risco cardiometabólico em adolescentes. Métodos Trata-se de estudo transversal com 327 adolescentes de 14 a 19 anos de idade. Investigaram-se dados sociodemográficos, antropométricos, pressóricos, bioquímicos e de consumo alimentar. O risco cardiometabólico foi calculado por meio da agregação dos fatores de risco, expressa pela soma dos escores Z. Realizou-se a regressão de Poisson para estimar as razões de prevalência. Resultados O baixo consumo de zinco associou-se a elevados níveis de CT e triglicérides para os meninos, e a níveis baixos de HDL-c e elevados de LDL-c e CT para as meninas, demonstrando risco. Além disso, a baixa ingestão de cobre associou-se a altos níveis de triglicérides e risco cardiometabólico para as meninas. A razão de prevalência nos níveis elevados de LDL-c, CT e risco cardiometabólico foi maior entre os adolescentes que apresentavam baixa ingestão de vitamina A. Foram observadas também associações, no sexo feminino, da menor ingestão de vitamina A com altos níveis de triglicérides. A baixa ingestão de vitamina C nos meninos mostrou associações com LDL-c e triglicérides elevado, enquanto nas meninas essa vitamina associou-se com menores níveis de HDL-c. O baixo consumo de vitamina E, para as meninas, apresentou associações com níveis baixos de HDL-c e elevados de CT. Conclusão As associações entre os micronutrientes antioxidantes e as alterações lipídicas e risco cardiometabólico ressaltam a importância de estimular o consumo de alimentos que sejam fonte desses nutrientes, com o objetivo de modular as alterações lipídicas e o risco cardiometabólico.

ABSTRACT Objective This study aimed at validating the associations between the consumption of antioxidant nutrients as well as lipid alterations and cardiometabolic risks in adolescents. Methods This cross-sectional study included 327 adolescents aged 14-19 years. Sociodemographic and dietary information, anthropometric and blood pressure measurements, and biochemical data were obtained. Cardiometabolic risk was calculated by aggregating the risk factors, which were expressed as the sum of Z-scores. Poisson regression was performed to estimate the prevalence ratios. Results In boys, low intake of zinc was associated with elevated total cholesterol and triglyceride levels, whereas it was associated with low high-density lipoprotein cholesterol levels and high low-density lipoprotein cholesterol and total cholesterol levels in girls, thus indicating a cardiometabolic risk. Furthermore, low intake of copper was associated with high triglyceride levels and cardiometabolic risk in girls. The high prevalence ratios of high low-density lipoprotein cholesterol and total cholesterol levels and cardiometabolic risk were higher in those with low intake of vitamin A. Among girls, associations were also observed between lower intake of vitamin A and high triglyceride levels. Low intake of vitamin C among boys was associated with elevated high low-density lipoprotein cholesterol and triglyceride levels. Among girls, the intake of this vitamin was associated with lower low high-density lipoprotein cholesterol levels. In girls, low intake of vitamin E was associated with low low high-density lipoprotein cholesterol levels and high total cholesterol levels. Conclusion The associations between antioxidant micronutrients as well as lipid alterations and cardiometabolic risk emphasize the importance of encouraging the consumption of foods that are rich in these nutrients to modulate lipid alterations and cardiometabolic risk.
