[Screen time, quality of the adolescent diet, and profile of the school environment]. / Tempo de tela, qualidade da dieta de adolescentes e características do entorno escolar.

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.

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.

Dietary patterns and socioeconomic, demographic, and health-related behaviors during pregnancy. A cross-sectional study

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.

Programa de incentivo ao aleitamento materno em creches de Curitiba-PR: percepção de profissionais da educação infantil / Breastfeeding Incentive Program in daycare centers in Curitiba-PR: perception of early childhood education professionals

O objetivo deste estudo foi verificar a percepção de profissionais da educação infantil quanto ao programa de incentivo ao aleitamento materno em creches do município de Curitiba-PR. Estudo transversal, de caráter quantitativo, realizado em 40 centros municipais de educação infantil (CMEI) participantes do Programa Mama Nenê. Ao todo, participaram do estudo 108 profissionais. Para a coleta de dados, foram aplicados questionários estruturados com perguntas fechadas. Foi realizada análise descritiva dos dados. Com base na percepção dos profissionais entrevistados, as creches analisadas incentivam o aleitamento materno por meio do Programa Mama Nenê, utilizando estratégias significativas. Contudo, foi verificada baixa adesão das mães à iniciativa de usar os espaços físicos das creches para amamentar, conhecidos como "cantinhos da amamentação". Para a criação de condições mais favoráveis à continuidade da amamentação nestas instituições, a educação em saúde e a adequação das leis que protegem mulheres trabalhadoras que amamentam são questões fundamentais.

The aim of this study was to assess the perception of early childhood education professionals about the breastfeeding incentive program at daycare centers in the city of Curitiba, state of Paraná. This is a cross-sectional, quantitative study carried out at 40 daycare centers participating in the Program "Mama Nenê". A total of 108 professionals participated in the study. For data collection, structured questionnaires with closed questions were applied. A descriptive data analysis was performed. According to the perception of the professionals interviewed, the daycare centers analyzed encourage breastfeeding through the Program "Mama Nenê", using significant strategies. However, a low adherence by mothers to the use of the spaces of the institutions for breastfeeding, the so called "breastfeeding corners", was observed. To create more favorable conditions for the continuity of breastfeeding in daycare centers, health education and the adequacy of laws protecting working women who breastfeed are key issues. (AU)
