Resumo: Abstract The proportion of non-participation in cohort studies, if associated with both the exposure and the probability of occurrence of the event, can introduce bias in the estimates of interest. The aim of this study is to evaluate the impact of participation and its characteristics in longitudinal studies. A systematic review (MEDLINE, Scopus and Web of Science) for articles describing the proportion of participation in the baseline of cohort studies was performed. Among the 2,964 initially identified, 50 were selected. The average proportion of participation was 64.7%. Using a meta-regression model with mixed effects, only age, year of baseline contact and study region (borderline) were associated with participation. Considering the decrease in participation in recent years, and the cost of cohort studies, it is essential to gather information to assess the potential for non-participation, before committing resources. Finally, journals should require the presentation of this information in the papers.

El objetivo de este estudio es realizar una revisión sistemática y un metaanálisis de artículos que describen la participación en estudios de cohortes y evaluar las características asociadas con la participación. Una revisión sistemática fue realizada (MEDLINE, Scopus y Web of Science), en busca de artículos que describen la relación de participación basada en estudios de cohortes. Se seleccionaron 2964 artículos, de los cuales se identificaron preliminarmente 50. Entre estos, la proporción promedio de participación fue de un 64,7%. Utilizando la metarregresión, sólo la edad, años de referencia y la región de estudio (borderline) se asociaron con la participación. Teniendo en cuenta la disminución de la participación en los últimos años, y el coste de los estudios de cohortes, es esencial buscar información para evaluar el potencial de la no participación antes de comprometer recursos.Resumo A proporção de não-participação em estudos de coorte está associada também à exposição e à probabilidade de ocorrência do evento poder gerar viés nas estimativas de interesse. O objetivo do presente trabalho é realizar uma revisão sistemática e metanálise de artigos que descrevem a participação em estudos de coorte e avaliar as características associadas à participação. Foi realizada uma revisão sistemática (MEDLINE, Scopus e Web of Science), buscando-se artigos que descrevessem a proporção de participação na linha de base de estudos de coorte. De 2.964 artigos inicialmente identificados, foram selecionados 50. Entre esses, a proporção média de participação foi de 64,7%. Utilizando-se o modelo de metarregressão com efeitos mistos, somente a idade, ano da linha de base e a região do estudo (limítrofe) estiveram associados à participação. Considerando a diminuição na participação em anos mais recentes e o custo dos estudos de coorte, é essencial buscar informações que permitam avaliar o potencial de não-participação antes de comprometer os recursos.Reports in Public HealthCadernos de Saúde Pública2015-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5706Reports in Public Health; Vol. 31 No. 11 (2015): NovemberCadernos de Saúde Pública; v. 31 n. 11 (2015): Novembro1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5706/11875https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5706/11876Sérgio Henrique Almeida da Silva JuniorSimone M.
