ABSTRACT
ABSTRACT BACKGROUND: The identification and understanding of dietary factors and other characteristics that influence gestational weight gain can contribute to the formulation of strategies to promote healthy eating habits before and during pregnancy. OBJECTIVE: To investigate the association between dietary patterns, sociodemographic and obstetric characteristics, and health-related behaviors in pregnant women. DESIGN AND SETTING: A cross-sectional study was conducted on women undergoing prenatal care in the Unified Health System of Colombo, Paraná, Brazil, from February 2018 to September 2019. METHOD: A weekly food frequency questionnaire was administered, and dietary patterns were identified through factor analysis. Median regression models were constructed to identify the associations between dietary pattern scores and variables. RESULTS: Complete data were obtained from 495 pregnant women. Three dietary patterns were identified: 1) "healthy," with higher factor loadings for the weekly consumption of raw vegetables, cooked vegetables, and fresh fruits; 2) "Western," including soft drinks or artificial juice, candies, milk, and dairy products, and processed cold meat; and 3) "traditional," beans and meat. Pregnant women aged 30 years or older (coefficient [Coef.] 0.86, 95% confidence interval [CI] 0.38-1.33) with moderate/intense physical activity (Coef. 0.32, 95% CI 0.02-0.62) had higher adherence to the "healthy" pattern. Adolescents and smokers adhered more to the "traditional" pattern (Coef. 0.17, 95% CI 0.01-0.33). CONCLUSION: Age, smoking status, and physical activity were associated with dietary patterns in pregnant women.
ABSTRACT
Resumo Objetivou-se investigar a associação entre o tempo de uso excessivo de diferentes telas, a qualidade da dieta em adolescentes e características do entorno escolar. Adolescentes de 30 escolas estaduais de Curitiba/PR relataram tempo de tela: televisão, videogame e portáteis. A qualidade da dieta foi avaliada pela frequência de consumo de alimentos. A renda do entorno escolar foi obtida do Censo. O ambiente construído para atividade física investigado por observação sistemática do entorno escolar. A regressão de Poisson multinível foi empregada para estimar associações com as variáveis de exposição. Entre 1.200 adolescentes, 50,9% do sexo masculino, 74,4% tiveram tempo excessivo de tela. O tempo excessivo de TV (56,5%) esteve associado à pior qualidade da alimentação. O tempo excessivo de videogame (22,0%) foi menor no sexo feminino (RP 0,25; IC95% 0,18;0,36), associado à pior qualidade da alimentação, à menor renda do entorno escolar, e à pior classificação do ambiente construído para atividade física. O tempo excessivo de telas portáteis (53,2%) apresentou tendência de aumento com a renda do entorno escolar. O uso excessivo de TV e telas portáteis foi amplamente praticado por adolescentes, com diferentes variáveis demográficas e contextuais associadas de acordo com o tipo de dispositivo utilizado.
Abstract Adolescents from 30 state schools in Curitiba, State of Paraná, reported total screen time, namely television, video games and laptops. Diet quality was assessed by the frequency of food consumption. The income of the school environment was taken from the Census. The built environment for physical activity was investigated by systematic observation of the school surroundings. Multilevel Poisson Regression was used to estimate associations with the exposure variables. Among 1,200 adolescents, 50.9% being male, and 74.4% were found to be exposed to excessive screen time. Excessive TV screen time (56.5%) was associated with poor diet quality. Excessive video game time (22.0%) was lower among females (PR 0.25; 95%CI 0.18;0.36), associated with poor diet quality, lower school environment income, and the worst classification of the built environment for physical activity. Excessive use of portable screens (53.2%) tended to increase with the income of the school environment. Excessive use of TV and laptops was widespread among adolescents, with different demographic and contextual variables associated according to the type of device used.
ABSTRACT
Esta pesquisa teve como objetivo verificar a aceitação de batatas Ágata minimamente processada por universitários de uma Instituição de Ensino Superior. As batatas foram lavadas em água corrente, descascadas, cortadas e sanitizadas em água clorada, imersas em solução antioxidante de ácido ascórbico e centrifugadas. O material foi embalado a vácuo armazenado sob refrigeração a 5ºC por três dias. Os resultados da avaliação sensorial demonstraram que os produtos processados apresentaram aspectos de frescor e foram bem aceitos antes e após a cocção em todos os atributos avaliados.
