The diet of adolescents had insufficient energy intake and deficient intake of fruits and vegetables. Meal patterns were satisfactory, but breakfast should be encouraged.
RESUMOObjetivo: Caracterizar comportamento de risco para transtornos alimentares (TA) e sua frequência entre adolescentes em uma revisão da literatura nacional e internacional. Méto-dos: Foi realizada uma busca bibliográfica por meio de uma revisão integrativa nas bases de dados PubMed (US National Library of Medicine) e Lilacs e no portal SciELO, utilizando-se os descritores relacionados à "eating disorder risk behavior". Foram selecionados artigos publicados nos últimos 10 anos, nos idiomas português, espanhol e inglês, e especificamente com adolescentes. Foram avaliados 76 artigos e analisados a nomenclatura e os instrumentos utilizados para avaliar comportamento de risco para TA e sua prevalência. Resultados: Encontrou-se uma série de termos para avaliar risco para TA. A metodologia mais utilizada foi a de questionários e escalas, destacando-se o EAT-26 ou 40 e o BITE, dentre os mais frequentes; a prevalência de risco variou de 0,24% a 58,4%. Conclusão: Diferentes nomenclaturas e instrumentos são utilizados para avaliar comportamento de risco para TA entre adolescentes, com grande amplitude nos resultados de prevalência. Maior padronização de termos e metodologia de avaliação permitiriam melhor comparação entre estudos epidemiológicos em diferentes localidades.
ABSTRACTObjective: To characterize eating disorder (ED) risk behavior and its prevalence among adolescents in a review of national and international literature. Methods: We carried out an integrative review on PubMed (U.S. National Library of Medicine), Lilacs and SciELO, using descriptors related to "eating disorder risk behavior". Articles published in the last 10 years, in Portuguese, Spanish and English, and specifically with adolescents were selected. The nomenclature and instruments used to assess eating disorder risk behaviors and its frequency were evaluated and analyzed in 76 articles. Results: Several terms to assess ED risk behavior were found; questionnaires and scales were used, mainly EAT-26 or 40 and BITE. The prevalence of risk ranged from 0.24% to 58.4%. Conclusion: Different names and instruments are used to assess ED risk behavior among adolescents, and there is a wide variation in the prevalence. Standardization of terms and evaluation methodology might enhance a better comparison of epidemiological studies in different locations.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
