Resumo: | ObjectiveTo investigate the association between television-viewing time and adolescent food intake. MethodsThis cross-sectional study included 815 male and female adolescents from public schools in Piracicaba, São Paulo. The following data were collected: sociodemographic and anthropometric data, television-viewing time, and habitual food intake. The latter was obtained by a food frequency questionnaire to assess the intake adequacy (servings/day) of seven food groups according to the Brazilian Food Guide. Television-viewing time regarded the total number of hours per day dedicated to watching television, which was then classified into two categories: ≤2 hours/day and >2 hours/day. The Student’s t test measured the difference between themeans of the continuous variables. The relationship between the independent variables and television-viewing time was tested by Poisson regression. ResultsAdolescents with higher television-viewing time consumed more milk and dairy products (p=0.03), sugars and sweets (p=0.01), and soda (p=0.02). Low fruit intake, high sweet, sugar, and soda intakes, and lower age were associated with higher television-viewing time. In multivariate analysis unhealthy food habits, such as low fruit intake (p=0.014) and high sugar and sweet intakes (p=0.041), remained independently associated with television-viewing time. ConclusionHigh television-viewing time was associated with poor eating habits. Adolescents with high television-viewing time should be encouraged to make healthier food choices, since poor eating habits and physical inactivity increase the risk of chronic diseases already during adolescence, especially when combined. |

Objetivo Investigar a associação entre o tempo diante da televisão e o consumo alimentar de adolescentes. Métodos Trata-se de estudo transversal com 815 adolescentes de ambos os sexos, de escolas públicas de Piracicaba, São Paulo. Foram obtidos dados sociodemográficos e antropométricos, bem como sobre o tempo despendido em frente à televisão e o consumo alimentar habitual. Este último foi obtido mediante aplicação do Questionário de Frequência Alimentar, avaliando-se a adequação do consumo (porções/dia) de sete grupos alimentares conforme recomendação do Guia Alimentar Brasileiro. O tempo de televisão foi obtido a partir do total de horas diárias dedicadas a assistir à televisão, sendo classificadas duas categorias: <2 horas/dia e >2 horas/dia. Utilizou-se o teste t de Student para avaliar a diferença de médias entre as variáveis contínuas. A relação entre variáveis independentes e tempo de televisão foi testada pela regressão de Poisson. Resultados Os adolescentes que permanecem mais tempo em frente à televisão consumiram mais leite e derivados (p=0,03), açúcares e doces (p=0,01) e refrigerante (p=0,02). Observou-se que o baixo consumo de frutas, assim como o consumo excessivo de doces, açúcares e refrigerantes e a menor idade, estavam associados ao maior tempo de televisão. Na análise multivariável, hábitos alimentares não saudáveis, como a baixa ingestão de frutas (p=0,014) e o consumo elevado de doces e açúcares (p=0,041), permaneceram independentemente associados ao tempo de televisão. ConclusãoO tempo excessivo em frente à televisão se associou a hábitos alimentares inadequados. Os adolescentes que permanecem tempo excessivo em frente à televisão devem ser incentivados a adotar uma prática alimentar mais saudável, já que a alimentação inadequada e o sedentarismo, sobretudo em associação, aumentam o risco de doenças crônicas ainda na adolescência.Núcleo de Editoração – PUC-Campinas2023-03-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/8041Brazilian Journal of Nutrition; Vol. 29 No. 3 (2016): Revista de NutriçãoRevista de Nutrição; Vol. 29 Núm. 3 (2016): Revista de NutriçãoRevista de Nutrição; v. 29 n. 3 (2016): Revista de Nutrição1678-9865reponame:Revista de Nutriçãoinstname:Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)instacron:PUC_CAMPenghttps://periodicos.puc-campinas.edu.br/nutricao/article/view/8041/5554Copyright (c) 2023 Carla Cristina ENES, Beatriz Guerra LUCCHINIhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess ENES, Carla CristinaGuerra LUCCHINI, Beatriz 2023-03-23T18:32:17Zoai:ojs.periodicos.puc-campinas.edu.br:article/8041Revistahttp://www.scielo.br/rnPRIhttps://periodicos.puc-campinas.edu.br/nutricao/oai||sbi.submissionrn@puc-campinas.edu.br1678-98651415-5273opendoar:2023-03-23T18:32:17Revista de Nutrição - Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)false |
