ABSTRACT
OBJECTIVE: To analyze the studies that identified the frequency of meals ingested by Brazilian adolescents and associated habits. DATA SOURCES: A systematic search was made in the databases and electronic databases: MEDLINE/PubMed, The Latin American and Caribbean Center of Information in Health Sciences (BIREME), Scopus, Web of Science and Embase, with articles published between January/2007 until December/2017, which addressed the evaluation of the frequency of meals performed by adolescents, considering or not associations with eating patterns and meal replacement. DATA SYNTHESIS: 6,608 studies were obtained through the search and nine were included in this review, all of them with a cross-sectional design. Eight studies used school surveys and only one was a population survey. Seven studies evaluated the frequency of the main daily meals that ranged from 47.0 to 79.0% at breakfast, from 65.0 to 98.4% at lunch, and from 51.0 to 94.0% at dinner. Five studies identified the frequencies of consumption of snacks between meals, finding higher values for afternoon snack (variation from 42.0 to 78.0%). Regarding the substitution of meals for snacks, in three of the four selected studies; it was observed that this practice occurred mainly in substitution of dinner (24.6 to 42.0%). CONCLUSIONS: Breakfast was the most omitted meal for adolescents, and dinner was replaced with snacks. Among the between meal snacks, the afternoon snack was the most consumed.

RESUMO Objetivo: Analisar os estudos que identificaram a frequência de refeições ingeridas por adolescentes brasileiros e hábitos associados. Fonte de dados: Efetuou-se uma busca sistemática nos bancos e nas bases de dados eletrônicos MEDLINE/PubMed, The Latin American and Caribbean Center of Information in Health Sciences (BIREME), Scopus, Web of Science e Embase, com artigos publicados entre janeiro de 2007 e dezembro de 2017, que abordaram a avaliação da frequência das refeições realizadas por adolescentes, considerando ou não as associações com padrões alimentares e substituição de refeições. Síntese dos dados: Foram obtidos 6.608 estudos por meio da busca e incluídos nove nesta revisão, todos de delineamento transversal. Oito deles utilizaram inquéritos escolares e apenas um tratava-se de inquérito populacional. Sete estudos avaliaram a frequência das principais refeições diárias que oscilaram de 47,0 a 79,0% no café da manhã, de 65,0 a 98,4% no almoço e de 51,0 a 94,0% no jantar. Cinco estudos identificaram as frequências de consumo de lanches intermediários, encontrando valores mais elevados para o lanche da tarde (variação de 42,0 a 78,0%). Em relação à substituição de refeições por lanches, em três dos quatros estudos selecionados, observou-se que essa prática ocorreu principalmente no jantar (24,6 a 42,0%). Conclusões: O café da manhã foi a refeição mais omitida pelos adolescentes, e o jantar, a mais substituída por lanches. Entre os lanches intermediários, o da tarde foi o mais consumido.

RESUMO Objetivo: Verificar a efetividade de intervenções educacionais baseadas na orientação sobre atividade física e nutrição em escolares. Fonte de dados: Foi realizada busca sistemática em quatro bancos e bases de dados eletrônicos, com artigos publicados entre outubro de 2007 e janeiro de 2017 que abordaram a realização de intervenções educacionais com ênfase em educação nutricional e atividade física ou exercício físico em escolares com idades entre 10 e 19 anos. Síntese dos dados: Foram selecionados 12 artigos para esta revisão. Desses estudos, quatro incluíram a intervenção educacional; quatro associaram intervenções educacionais à inclusão de alimentos saudáveis e atividade física; dois estudos relacionaram as orientações e a atividade física; e, por fim, dois ligaram as orientações com o consumo de alimentos saudáveis. Conclusões: As intervenções baseadas na orientação de atividade física e/ou nutrição foram eficientes, com resultados superiores nos estudos que associaram a prática de atividade física à orientação. Entretanto, observou-se a necessidade da realização de novos estudos que abordem as intervenções educacionais em escolares.
ABSTRACT Objective: To verify the effectiveness of educational interventions based on guidance on physical activity and nutrition in schoolchildren. Data sources: A systematic search was carried out in four electronic databases containing articles published between October 2007 and January 2017 and addressing educational interventions with emphasis on both nutritional education and physical activity in schoolchildren and adolescents aged 10 to 19 years. Data synthesis: Twelve articles were selected for this review, of which four included only educational interventions; four made and association between educational interventions, inclusion of healthy foods and physical activity; two made a relation between guidelines and physical activity; and finally, two associated guidelines with consumption of healthy foods. Conclusions: Interventions based on physical activity and/or nutrition counseling were efficient and showed superior results in studies that associated the practice of physical activity with counseling. However, the need for new studies on educational interventions among schoolchildren and adolescents was made evident.
