Resumo: | This study aimed to estimate the prevalence of anemia in Brazilian children, according to different epidemiological scenarios. For this purpose, we carried out a systematic review with meta-analysis of the results of observational studies published in the last ten years. Articles were searched in the SciELO and PubMed databases using the keyword “anemia” combined with children and Brazil. After establishing the exclusion criteria (review article, anemia not of a nutritional etiology, diagnosis not based upon the level ofhemoglobin (Hb<11g/dL), sample including children older than seven years, no prevalence data and no identification of study location, sample, age group and diagnostic method), 35 articles were selected, which were categorized according to the origin of their samples: daycare centers/schools n=8, health services n=12, populations subject to socioeconomic inequality n=6 and population-based studies n=9. A meta-analysis was used to estimate the prevalence of anemia weighted by the respective sample size, and odds ratio for a confidence interval of 95%, assuming the prevalence of population-based studies as reference (odds ratio =1). The following results were obtained, respectively: centers/schools: 52.0%, 1.61 (1.5 to 1.8); health services: 60.2%, 2.26 (2.1 to 2.4); populations subject to injustice: 66.5%, 2.96 (2.6 to 3.4) and population-based studies: 40.1%, with p<0.0001 for all comparisons (χ2). Anemia is still a serious public health problem in the different scenarios analyzed, justifying the fact that it is still considered a priority by managers of public health policies of different government levels in the country. |

Para isso, realizou-se uma revisão sistemática com metanálise dos resultados de estudos observacionais publicados nos últimos dez anos. A pesquisa de artigos foi efetuada nas bases do SciELO e PubMed, usando-se a palavra-chave “anemia” combinada com criança e Brasil. Após aplicação dos critérios de exclusão (artigos de revisão; anemia de etiologia não nutricional; diagnóstico não baseado no nível de hemoglobina (Hb<11g/dL); amostra envolvendo crianças >7 anos; ausência de dados de prevalência; e não identificação do local de estudo, da amostra, da faixa etária e/ou do método diagnóstico), foram selecionados 35 artigos, posteriormente categorizados segundo a origem de suas amostras: creches/escolas n=8, serviços de saúde n=12, populações em iniquidades n=6 e estudos de base populacional n=9. Por meio de metanálise, calcularam-se a prevalência média de anemia ponderada pelos respectivos tamanhos amostrais e a razão de chances para um intervalo de confiança de 95%, assumindo-se a prevalência de estudos de base populacional como referência n=1 (CRC=1), e obtiveram-se os seguintes resultados, respectivamente: creches/escolas: 52,0%, 1,61 (1,5-1,8); serviços de saúde: 60,2%, 2,26 (2,1-2,4); populações em iniquidades: 66,5%, 2,96 (2,6-3,4) e estudos de base populacional: 40,1%, com p<0,0001 para todas as comparações (χ2). A anemia continua representando um grave problema de saúde pública nos distintos cenários analisados, justificando receber atenção prioritária por parte dos gestores das políticas públicas das diferentes esferas de governo no País.Núcleo de Editoração – PUC-Campinas2023-08-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9379Brazilian Journal of Nutrition; Vol. 23 No. 3 (2010): Revista de NutriçãoRevista de Nutrição; Vol. 23 Núm. 3 (2010): Revista de NutriçãoRevista de Nutrição; v. 23 n. 3 (2010): Revista de Nutrição1678-9865reponame:Revista de Nutriçãoinstname:Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)instacron:PUC_CAMPporhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9379/6749Copyright (c) 2023 Regina Coeli da Silva VIEIRA, Haroldo da Silva FERREIRAhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCoeli da Silva VIEIRA, Regina da Silva FERREIRA, Haroldo 2023-08-28T17:20:57Zoai:ojs.periodicos.puc-campinas.edu.br:article/9379Revistahttp://www.scielo.br/rnPRIhttps://periodicos.puc-campinas.edu.br/nutricao/oai||sbi.submissionrn@puc-campinas.edu.br1678-98651415-5273opendoar:2023-08-28T17:20:57Revista de Nutrição - Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)false |
