RESUMO Objetivo: Fazer uma revisão da literatura sobre a relação entre sono, estado nutricional e padrão alimentar, bem como mecanismos associados, na população infantil. Fontes de dados: Foram realizadas buscas bibliográficas nas bases PubMed, LILACS e Scopus, usando os seguintes descritores: “Child”; “Nutritional status”; “Sleep”; “Physical activity OR Physical activities OR Exercise”. Os artigos que atenderam ao objetivo da pesquisa foram incluídos. Excluíram-se estudos de revisão, cartas para autores ou diretrizes. Síntese dos dados: Inicialmente, 402 artigos foram encontrados na pesquisa. Após análise dos títulos e abstracts e a aplicação dos critérios de exclusão, 24 estudos foram selecionados para a revisão. A maioria dos estudos (n=13) sugere que sono de curta duração (<9-10 horas/noite) está associado com sobrepeso/obesidade na população infantil. Apenas três artigos não reportaram associações entre variáveis do sono e estado nutricional. Curta duração do sono também foi associada a hábitos alimentares ruins, maior consumo de refrigerantes e bebidas estimulantes antes de deitar, bem como deficiência de micronutrientes. Conclusões: A duração do sono tem relação com sobrepeso e obesidade na população infantil. Alterações no padrão alimentar também têm relação com débito de sono, sendo um dos mecanismos que contribuem para o ganho de peso excessivo. É necessário que os profissionais de saúde tomem conhecimento da importância da qualidade do sono para a manutenção do estado nutricional em crianças.
Objective: To review the current literature on the relationship between sleep, nutritional status and eating behavior, as well as mechanisms associated with these elements in children. Data source: The literature research was conducted in the PubMed, LILACS and Scopus databases, using the following terms: “Child”; “Nutritional status”; “Sleep”; “Physical activity OR Physical activities OR Exercise”. The articles included were those that met the research objective. Review articles, letters to authors, or guidelines were excluded. Data synthesis: 402 articles were initially found in the literature search. After careful analyses of the title and abstract, and application of inclusion criteria, only 24 studies were included in the present review. Most studies (n=13) suggest that short sleep duration (<9-10 hours/night) is associated with overweight/obesity in children. Only three studies did not show associations between overweight/obesity and sleep variables. Short sleep duration is also associated with poor food quality, higher intake of soft drinks and stimulant beverages before bedtime, as well as micronutrient deficiency. Conclusions: Sleep duration is related to overweight and obesity development in infants. Changes in dietary pattern are also related to sleep debt, being one of the mechanisms that contribute to excessive weight gain. It is necessary that health professionals understand the importance of sleep quality in the nutritional status maintenance in children.
Introduction: The current pandemic scenario has brought consequences for the health of the child population, including changes in sleep and eating behavior. Objectives: The present study aimed to evaluate changes in sleep, eating habits and socioeconomic status during the pandemic outbreak. Methods: A longitudinal study with 37 children between 4-10 years old from a public school. Sleep habits were evaluated through the Questionnaire of Sleep Habits for Children (QSTC), food ingestion, through the 24-hour Recall, and collected socioeconomic data. Results: There was an increase in total sleep time (p<0.01) and a decrease in the overall sleep quality (p<0.01). A reduction in the number of meals consumed was observed (p<0.01). Higher consumption of ultraprocessed food was observed in relation to in natura, with no changes after pandemic. A socioeconomic decline was observed in 43.2% of families (p<0.01). Conclusion: Improvements in children's sleep quality and duration, a reduction in the number of meals per day and the loss of access to school meals was observed.
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.
