RESUMO
Background: The quantity and quality of Brazilian scientific output increases decade by decade. However, there is a tendency to undervalue Brazilian journals, illustrated by the low number of citations compared with texts in international journals, with the tacit justification that foreign articles are of superior quality. Objectives: To investigate the differences in numbers of citations of Brazilian and international periodicals in three Brazilian journals from 2016 to 2020. Methods: All articles published in the Journal of the Brazilian College of Surgeons, in the Jornal Vascular Brasileiro, and in Acta Cirúrgica Brasileira from 2016 to 2020 were analyzed. The references of these studies were analyzed, summing the total number of citations and classifying them as published in Brazilian or foreign journals. Results: A total of 902 articles were analyzed, totaling 23,394 references, with a mean of 25.81 ± 8.59 references per article. Of these, 2,680 (11.45%) were Brazilian, equating to a mean of 2.95 ± 3.79 Brazilian references per article. Conclusions: It is necessary to improve appreciation of Brazilian periodicals, especially among Brazilian researchers and institutions responsible for science funding.
RESUMO
Resumo Contexto A produção científica brasileira cresce de forma quantitativa e qualitativa a cada década. Entretanto, há uma desvalorização dos periódicos brasileiros demonstrada através da baixa quantidade de citações em comparação a textos de revistas internacionais, com justificativa subentendida de que há superioridade qualitativa de artigos estrangeiros. Objetivos Verificar a diferença entre o número de citações de periódicos nacionais e internacionais em três revistas brasileiras no período de 2016 a 2020. Métodos Foram analisados todos os artigos publicados na Revista do Colégio Brasileiro de Cirurgiões, no Jornal Vascular Brasileiro e na Acta Cirúrgica Brasileira no intervalo de 2016 a 2020. Os estudos selecionados tiveram suas referências avaliadas, sendo contabilizado o número total de citações e se eram provenientes de periódicos brasileiros ou de periódicos estrangeiros. Resultados Foram analisados 902 artigos, totalizando 23.394 referências, com média de 25,81 ± 8,59 por artigo. Nesse contexto, 2.680 (11,45%) eram nacionais, correspondentes a uma média de 2,95 ± 3,79 referências brasileiras por artigo. Conclusões Faz-se necessária a maior valorização dos periódicos brasileiros, em especial por parte dos pesquisadores nacionais e das instituições responsáveis pelo fomento da ciência.
