Resumo: The objective of this study was to assess the validity and reproducibility of a food frequency questionnaire to assess intake of the food groups included in the food guide pyramid for adolescents (FFQ-FP). The final version of the FFQ-FP consisted of 50 food items. The study was carried out with a sample of 109 adolescents over a period of four months. A 24hr recall (24hr) was conducted four times and the FFQ-FP was conducted twice. Validity was determined by comparing the second FFQ-FP and the mean of the four 24hrs, while reproducibility was verified by comparing the results of the two FFQ-FPs. Statistical analysis was carried out using medians, standard deviations, Pearson and intraclass correlations and Kappa statistics to assess concordance. Best results were achieved for the rice (including bread, grains and starches), meats and sugars groups. Weakest correlation was observed for the variable vitamin C. The validity and reproducibility of the FFQ-FP was satisfactory for most variables.

Después de identificar los alimentos que se incluyen en el FFQ-AP, la versión final estuvo compuesta por 50 ítems. El estudio se realizó con 109 adolescentes durante un período de cuatro meses. Se realizaron cuatro recordatorios de 24 horas dietéticos (R24h) y dos FFQ-AP. La validez se evaluó mediante la comparación del segundo cuestionario de frecuencia (FFQ-AP) y el promedio de los R24h, mientras que la reproducibilidad se evaluó mediante la comparación de los dos FFQ-AP. Los análisis estadísticos se realizaron con medias, desviaciones estándar y correlaciones de Pearson y correlación intraclase. Los grupos de alimentos con variables evaluadas fueron: arroz, pan, pasta, patatas y yuca, carne y azúcar y dulces. Los peores resultados se observaron con respecto a la vitamina C. El FFQ-AP mostró una validez aceptable y de reproducción satisfactoria para la mayoría de las variables.O objetivo foi verificar a validade e reprodutibilidade de um questionário de frequência alimentar baseado nos grupos alimentares da pirâmide alimentar para adolescentes (QFA-PA). Após a identificação dos alimentos a serem incluídos no QFA-PA, a versão final consistiu em 50 itens. O estudo foi realizado com 109 adolescentes durante um período de quatro meses. Foram aplicados quatro recordatórios de 24h (R24h) e dois QFA-PA. A validade foi obtida pela comparação entre o segundo QFA-PA e a média dos R24h, enquanto que a reprodutibilidade foi mensurada por meio da comparação dos dois QFA-PA. As análises estatísticas foram realizadas utilizando-se médias, desvios-padrão, correlações de Pearson, e intraclasse e concordância. As variáveis melhor avaliadas foram os grupos do arroz, pão, massa, batata e mandioca, das carnes e de açúcares e doces. Os piores resultados foram observados para a vitamina C. O QFA-PA apresentou validade satisfatória e reprodutibilidade aceitável para a maioria das variáveis.Reports in Public HealthCadernos de Saúde Pública2013-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5246Reports in Public Health; Vol. 29 No. 9 (2013): SeptemberCadernos de Saúde Pública; v. 29 n. 9 (2013): Setembro1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5246/10761https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5246/10762Martinez, Marcelle FloresPhilippi, Sonia TucunduvaEstima, CamillaLeal, Greisseinfo:eu-repo/semantics/openAccess2024-03-06T15:28:37Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/5246Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:06:02.715559Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true
