Zusammenfassung: | ABSTRACT The accelerated modernization process has entailed changes in the lifestyle of people, such as exposure to sedentary behavior, and this in turn may affect the nutritional status. The aim of this systematic review with meta-analysis was to analyze observational studies that assessed the association between exposure time to sedentary behavior and nutritional status (overweight/malnutrition) in individuals aged ≥60 years. BVS, PubMed and Web of Science were the databases used in the search for observational studies, published until November 28, 2017, which have examined the association between exposure time to sedentary behavior and nutritional status. Two authors undertook the reading of titles and abstracts and applied the STROBE checklist independently. The Odds Ratio was calculated using the random effects model. Eight studies were included in this meta-analysis and involved 21415 individuals. All the studies covered most of the items suggested by the STROBE checklist. Of the total, four studies showed association between sedentary behavior and nutritional status. Longer exposure to sedentary behavior did not increase the odds of overweight and/or obesity (OR 1.32; 95%; CI 0.95-1.84). It is suggested that further studies with standardized criteria for measuring sedentary behavior and nutritional status are undertaken. Level of Evidence II; Systematic review of level II studies.
RESUMO O acelerado processo de modernização tem acarretado mudanças no estilo de vida das pessoas, como a exposição ao comportamento sedentário, e esta, por sua vez, pode afetar o estado nutricional. O objetivo desta revisão sistemática com metanálise foi analisar estudos observacionais, que avaliaram a associação entre tempo de exposição ao comportamento sedentário e estado nutricional (excesso de peso/desnutrição) em indivíduos com idade ≥ 60 anos. BVS, PubMed e Web of Science foram as bases de dados utilizadas para a busca de estudos observacionais, publicados até 28 de novembro de 2017, que analisaram a associação entre tempo de exposição ao comportamento sedentário e estado nutricional. Dois autores realizaram a leitura de títulos e resumos e aplicaram o checklist STROBE de forma independente. Odds Ratio foi calculado utilizando o modelo de efeito aleatório. Foram incluídos nesta metanálise oito estudos, envolvendo 21415 indivíduos. Todos os estudos atenderam a maior parte dos itens sugeridos pelo checklist STROBE. Do total, quatro estudos apresentaram associação entr |
