As doenças crônicas não-transmissíveis são um importante problema de saúde pública, sendo responsáveis pelas maiores taxas de morbimortalidades no Brasil. Poucos estudos epidemiológicos avaliam se o momento da ingestão de álcool, com ou sem refeição, associa-se com o desenvolvimento de doenças crônicas. Este estudo tem como objetivo investigar as associações de consumo de bebidas alcoólicas (quantidade, momento e tipo de bebida) com os indicadores de obesidade (IMC, circunferência da cintura, %gordura corporal total e %gordura no tronco) e a incidência de Síndrome Metabólica (SM) e de seus componentes. O Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) é um estudo de coorte que iniciou em 2008 e está distribuído em seis Centros Investigativos no Brasil – Universidade Federal do Rio Grande do Sul, Universidade de São Paulo, Fundação Oswaldo Cruz (Rio de Janeiro), Universidade Federal da Bahia, Universidade Federal do Espírito Santo e Universidade Federal de Minas Gerais. No ano de 2015 foi finalizada a segunda visita de coleta de dados, possibilitando análises longitudinais. As associações entre consumo de álcool com os indicadores de obesidade foram apresentadas testando as diferenças das médias na análise de variância, na amostra geral e separadamente por sexo (análise transversal). A associação de consumo de álcool com SM incidente e seus componentes foi investigada em modelos de regressão de logística (análise longitudinal). Para ambas análises utilizou-se uma parametrização que representa as combinações entre a quantidade de álcool e momento de consumo. As análises foram ajustadas para potenciais confundidores (sexo, idade, cor/raça, escolaridade, tabagismo e atividade física (artigos 1 e 2); + consumo calórico (kcal) e IMC basal (artigo 2). A análise dos dados foi realizada utilizando-se o software SAS versão 9.4, adotando um nível de significância de 5%. A pesquisa seguiu os preceitos éticos que envolvem seres humanos, em conformidade com a resolução 466/12. Em análises ajustadas, foi observado que o consumo leve a moderado de álcool, junto das refeições, foram associados a menores médias de IMC, circunferência da cintura, %gordura corporal total e %gordura no tronco; o maior consumo, fora das refeições, apresentou maiores médias desses indicadores. Da mesma forma, consumo leve de bebidas alcoólicas com refeições foi associado a menor incidência de SM, pressão arterial elevada e redução de HDL-c, enquanto o maior consumo, fora das refeições, foi associado à elevada incidência de componentes da SM. Estes achados apoiam as considerações de que o álcool, quando ingerido, deve ser preferencialmente consumido em pequenas quantidades e junto das refeições. Noncommunicable chronic diseases are a major public health problem and are responsible for the highest morbidity and mortality rates in Brazil. Few epidemiological studies have assessed whether the timing of alcohol intake, with or outside of meals, is associated with the development of chronic diseases. This study aims to investigate the associations of alcohol consumption (amount, timing and type) with obesity indicators (BMI, waist circumference, % total body fat mass and %trunk fat mass) and the incidence of metabolic syndrome (MS) and its components. The Longitudinal Study of Adult Health (ELSA-Brasil) is a cohort study that began in 2008 and is distributed in six Investigative Centers in Brazil - Federal University of Rio Grande do Sul, University of São Paulo, Oswaldo Cruz Foundation (Rio de Janeiro), Federal University of Bahia, Federal University of Espírito Santo and Federal University of Minas Gerais. In 2015, the second visit of data collection was completed, enabling longitudinal analysis. Associations between alcohol consumption and obesity indicators were presented by testing the differences of means in the analysis of variance in the general sample and separately by sex (cross-sectional analysis). The association of alcohol consumption with incident MS and its components was investigated in logistic regression models (longitudinal analysis). For both analyses we used a parameterization that represents the combinations between the amount of alcohol and timing of consumption. The analyzes were adjusted for potential confounders (sex, age, skin color/race, education level, smoking and physical activity (articles 1 and 2); + caloric intake (kcal) and basal BMI (article 2). Data analysis was performed using SAS version 9.4 software, adopting a significance level of 5%. The research followed the ethical precepts involving humans, in accordance with resolution 466/12. In adjusted analysis, it was observed that light to moderate alcohol consumption with meals were associated with lower means of BMI, waist circumference, % total body fat mass and % trunk fat mass; while higher consumption, outside of meals, presented higher averages of these indicators. Similarly, light alcohol consumption with meals was associated with a lower incidence of MS, high blood pressure, and a reduction in HDL-c, while higher outside of meal consumption was associated with a high incidence of MS components. These findings support the view that alcohol, when taken, should preferably be consumed in small quantities and with meals.

- Abstract
Background: Poor knowledge about syphilis might contribute to its dissemination. This study aimed to assess the knowledge of the urban population of Rio Grande do Sul about syphilis and its associated factors, including presence of active syphilis infection. Methods: This cross-sectional study was representative of the urban population of the state of Rio Grande do Sul. Data collection, consisting of an in-person interview and capillary blood collection, was carried out between December 2020 and December 2022. Laboratory tests and quality control procedures were concluded by February 2023. Knowledge about syphilis was assessed by means of six items in the questionnaire: A)"Can a person that looks healthy be infected by syphilis?"; B)"Is there a cure for syphilis?"; C)"Is using a condom during sexual intercourse the best way to avoid syphilis?"; D)"Can syphilis infection increase the risk of transmitting or acquiring HIV/AIDS?"; E)"Can a pregnant woman infected with syphilis transmit the disease to her baby?"; F)"Can syphilis be transmitted by a handshake?". Participants that provided at least 4 correct answers were considered having adequate knowledge. Active syphilis infection was determined by a positive enzyme-linked immunosorbent assay and a positive confirmatory test (Venereal Disease Research Laboratory test or Treponema pallidum Hemagglutination Assay). Comparisons between those with adequate versus inadequate knowledge were made using chi-squared tests analyzing sex, age, educational level, condom use in the last sexual intercourse and active syphilis infection. Analyses took sample weights into account. Results: In total 7963 participants contributed with valid data to the study. Mean age was 49.1 (SE ± 0.7) years and 64.2% were female. Overall, 85% of participants presented adequate knowledge about syphilis. Separately, proportions of correct answers for A to F were: 89.3%; 61.1%; 93.6%; 69.8%; 68.1% and 85.6%, respectively. Age, educational level, condom use and active syphilis infection were associated with knowledge about syphilis. Conclusion: In this population of urban adults from Rio Grande do Sul, being younger and more educated was associated with adequate knowledge about syphilis. Active syphilis infection was also associated with adequate knowledge. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Rio Grande do Sul is a state in southern Brazil with an HIV epidemic with different characteristics than those of the rest of the country. This study aimed to assess the self-perception of risk of HIV infection in the population of Rio Grande do Sul. Methods: This cross-sectional study, which was representative of the urban adult population of Rio Grande do Sul, was carried out between December 2020 and February 2023. Data collection includes an in-person interview and the collection of a capillary blood sample. Self-perception of HIV risk infection was assessed by the item "How do you assess your risk of being infected by HIV/AIDS?", with the following alternatives: "No risk", "Low risk", "Medium risk" and "High risk". HIV infection was defined by a positive enzyme-linked immunosorbent assay and a detectable viral load test or rapid immunoblot assay. Participants with previously known HIV infection were excluded from this study. We used the Brazilian Criteria to define social status. Education level was categorized as "9th grade or less", "10-th grade - high schools graduate", "College (includes incomplete)". Sexual orientation was aggregated into two categories: heterosexual or nonheterosexual. The reported number of sexual partners in the last year was categorized into "one", "two or "three" or "more than three". Weighted frequencies were calculated taking into account probability weights for sex and municipality strata, and comparisons between groups were tested by means of chi-square tests. Results: In total, 4231 participants were included. Of these 51.7% perceived "No risk" of HIV infection, 39.6% perceived "Low risk" of HIV infection, 5.9% perceived "Medium risk" and 2.9% perceived "High risk". There were significant differences in selfreported risk according to age, social status, education level, sexual orientation, number of sexual partners and condom use in the last intercourse. There was no association between self-perceived risk and HIV infection. Conclusion: Older, poorer and less educated people perceived lower risk of HIV infection. Nonheterosexual persons, and persons with more than 1 partner in the last year perceived higher risk of HIV infection. Self-perceived risk of infection was not associated with HIV infection.

Objetivos: Relacionar o consumo de fibra alimentar e de gordura saturada com marcadores bioquímicos em indivíduos portadores de síndrome metabólica. Métodos: A base de dados deste estudo transversal foi formada por adultos de ambos os sexos com diagnóstico de síndrome metabólica conforme o National Cholesterol Education Programs Adult Treatment Panel III, participantes de um estudo realizado na Pontifícia Universidade Católica do Rio Grande do Sul. Foram utilizados os dados de todos os indivíduos cadastrados na linha de base que possuíam informações completas sobre o consumo alimentar. O consumo de fibra alimentar e de gordura saturada foi apurado a partir das informações obtidas de um recordatório alimentar 24 horas e de um registro alimentar de dois dias. Foram avaliados os sujeitos de forma geral e estratificados por sexo. A análise de dados foi realizada por estatística descritiva e teste t de Student. A correlação entre o consumo de fibras e de gordura saturada com marcadores bioquímicos foi obtida através do coeficiente de correlação de Pearson. Foi utilizado nível de significância de 5%. Resultados: Foram encontrados 79 indivíduos cujos registros continham as informações completas, sendo incluídos no estudo. Observou-se correlação positiva significativa do consumo de gordura saturada com níveis séricos de triglicerídeos (r=0,30; p=0,008) e com insulina (r=0,26; p=0,021). Além disso, observou-se correlação inversa significativa entre consumo de fibras e níveis séricos de HDL-colesterol (r=-0,28; p=0,011). Quando estratificados os indivíduos por sexo, observou-se que a correlação positiva entre consumo de gordura saturada e nível de triglicerídeos manteve-se significativa apenas entre os homens (r=0,44; p=0,034). Conclusões: Nessa população com diagnóstico de síndrome metabólica, foram encontrados níveis mais baixos de HDL-colesterol nos indivíduos que referiam maior consumo de fibra alimentar, enquanto os indivíduos que relataram elevado consumo de gordura saturada tiveram níveis mais altos de insulina e de triglicerídeos. Na análise estratificada por sexo, correlação positiva foi encontrada apenas entre consumo de gordura saturada e níveis séricos de triglicerídeos em homens

Introdução A prevalência de síndrome metabólica está aumentando em todo o mundo. Sua associação com o consumo de álcool é controversa na literatura e há uma falta de dados que explorem a influência de beber com ou sem refeições. Objetivo Investigar as associações de consumo de bebidas alcoólicas (quantidade, tipo predominante e momento de consumo) com a síndrome metabólica e seus componentes. Métodos Em análise transversal da linha de base do estudo ELSA-Brasil, foram incluídos 14.570 indivíduos. A associação entre a presença de síndrome metabólica e cada um dos seus componentes isolados com diferentes aspectos do consumo de álcool foi avaliada por meio de modelos de regressão logística com interações entre a quantidade consumida, a predominância do tipo de bebida (vinho, cerveja ou outra), e o momento mais frequente de consumo (junto às refeições, fora, ou tanto junto quanto fora). Resultados Em análises ajustadas por sexo, idade, cor da pele/raça, fumo, índice de massa corporal, nível educacional, renda per capita e classe socioeconômica, consumo leve (até 4 doses/semana) predominantemente de vinho junto das refeições esteve inversamente associado com síndrome metabólica (OR=0,69, IC95% 0,57 – 0,84), glicemia de jejum elevada (OR=0,83, IC95% 0,70 – 0,99), circunferência da cintura elevada (OR=0,65, IC95% 0,51 – 0,84) e baixo HDL-colesterol (OR=0,63, IC95% 0,50 – 0,79), comparados a quem não ingere bebida alcoólica regularmente. Beber predominantemente vinho, independente do momento de consumo, nunca foi associado significativamente com maiores chances de qualquer elemento da síndrome. Por outro lado, beber doses mais elevadas (mais de 7 doses/semana) predominantemente de cerveja, principalmente fora das refeições, esteve significativamente associado com síndrome metabólica (de 7 a 14 doses/semana: OR=1,43, IC95% 1,18 – 1,73; mais de 14 doses/semana: OR=1,70, IC95% 1,35 – 2,15), como também para cada um de seus componentes, com exceção de baixo HDL-colesterol. Conclusão A associação entre síndrome metabólica e alguns dos seus componentes individuais com o consumo de álcool diferiu-se em decorrência da predominância do tipo de bebida alcoólica e se ingerido junto ou fora das refeições. As chances de apresentar síndrome metabólica foram menores dentre indivíduos que consumiam pequenas doses predominantemente de vinho, em especial junto às refeições, enquanto que as chances foram maiores para aqueles que faziam uso predominante de cerveja, especialmente fora das refeições, em maiores quantidades. Background The prevalence of the metabolic syndrome is rising worldwide. Its association with alcohol intake is controversial, and data is sparse concerning the influence of drinking during, as opposed to outside of meals. Aims We aimed to investigate the associations of different aspects (quantity, predominant beverage and moment of consumption) of alcohol consumption with the metabolic syndrome and its components. Methods We analyzed cross-sectionally 14,570 individuals who participated in the ELSABRASIL baseline, fitting logistic regression models investigating interactions between the quantity of alcohol, predominant beverage type (wine, beer or other), and principal moment of consumption with respect to meals. Results In analyses adjusted for sex, age, race, smoking, body mass index, educational level, per capita income and socioeconomic class, light consumption (up to 4 doses/week), predominantly of wine and with meals was inversely associated with the metabolic syndrome (OR=0.69, 95%CI 0.57 – 0.84), elevated fasting glucose (OR=0.83, CI95% 0.70 – 0.99), elevated waist circumference (OR = 0.65, CI95% 0.51-0.84) and reduced HDL-cholesterol (OR=0.63 95%CI 0.50 – 0.79), compared to abstention/eventual drinking. Drinking predominantly wine, regardless of the moment of consumption, was never significantly associated with higher odds of any component of the syndrome. On the other hand, greater consumption of alcohol (>7 doses/week), predominantly as beer, when mainly not consumed with meals was significantly associated with the metabolic syndrome (7 to 14 doses/week: OR=1.43, 95%CI 1.18 – 1.73; more than 14 doses/week: OR = 1.70, 95%CI 1.35 – 2.15) and with syndrome components, except for low HDL-cholesterol. Conclusion The association of alcohol consumption with the metabolic syndrome and many of its individual components differed markedly by predominant beverage and the consumption´s relationship to meals. Odds of having the metabolic syndrome were lower among individuals who consumed small doses, predominantly of wine, especially with meals, while odds were higher for those who drank predominantly beer, especially when unrelated to meals, and in larger quantities.

- Abstract
Introduction: Lipid Accumulation Product (LAP) Index correlates to cardiovascular risk factors in general population but it has not been tested in hospitalized patients., Objectives: We aimed to evaluate associations between LAP Index and metabolic profile in a tertiary hospital., Methods: Cross-sectional study with 90 inpatients. Lipid profile, fasting glucose, systolic and diastolic blood pressure measurements were obtained from electronic medical records. Weight, height and waist circumferences (WC) were assessed; Body Mass Index (BMI) and LAP Index were calculated. Data were expressed as mean ± standard deviation or percentage. Pearson's correlation and Multiple Linear Regression were used to assess the objectives., Results: Mean age of participants was 55.03 ± 14.86 years and 47.8% (n = 43) were men. After adjustment for sex, age and physic activity LAP Index (log-transformed) was significantly associated with HDL-cholesterol (p < 0.001), fasting glucose (p = 0.02), systolic blood pressure (p = 0.03) and a trend toward total cholesterol (p = 0.07)., Conclusion: There are independent association between LAP Index (log-transformed) and metabolic profile in hospitalized patients., (Copyright AULA MEDICA EDICIONES 2014.
