Resumo: | ObjectiveThe objective of this study is to assess the relationship between breastfeeding and hemoglobin concentration in children under 2 years of age in Itupeva City, SP, Brazil. MethodsThis cross-sectional population-based study was carried out in a representative sample of 254 children under 2 years of age randomly selected in the urban area of Itupeva, SP. The sampling process was done in three stages. The recommendations made by the World Health Organization were used to classify breastfeeding. Hemoglobin concentration was measured by the cyanmethemoglobin method, using the HemoCue system and anemia was defined when hemoglobin concentration was below 11.0g/dL. ResultsThe prevalence of anemia was 41.7%. Anemia was more frequent among children who were weaned before 6 months (p<0.05). The mean hemoglobin levels of breastfed children were significantly higher among children under 6 months (p<0.05). Children who were exclusively or predominantly breastfed in the first six months of life had higher mean hemoglobin levels than the remaining children (12.3g/dL versus 10.99g/dL; p=0.022). ConclusionsThe results suggest that partial or total substitution of breast milk before six months of age was associated with lower mean hemoglobin levels. The high frequency of anemia and the low percentage of children who were exclusively breastfed indicate that programs are needed to control nutritional anemia in this city and to promote exclusive breastfeeding in the first six months. |

MétodosEstudo transversal de base populacional, realizado em amostra representativa de 254 crianças menores de 2 anos, selecionadas aleatoriamente na área urbana de Itupeva, SP, por procedimento de amostragem por conglomerados em 3 etapas. O aleitamento materno foi classificado utilizando-se as recomendações da Organização Mundial da Saúde e a hemoglobina foi determinada em hemoglobinômetro portátil (HemoCue). Para o diagnóstico, utilizou-se o ponto de corte de 11,0g/dL. ResultadosA prevalência de anemia foi de 41,7%. Anemia foi mais freqüente entre os menores de 6 meses que não se encontravam em aleitamento materno (p<0,05). As médias de hemoglobina das crianças em aleitamento materno também se mostraram significantemente mais elevadas entre os menores de 6 meses (p<0,05). Nessa mesma faixa etária, a média de hemoglobina das crianças em aleitamento materno exclusivo e predominante foi significantemente maior do que a observada nas crianças em alimentação artificial (12,30g/dL versus 10,99g/dL; p=0,022). ConclusãoOs resultados encontrados sugeriram que a substituição parcial ou total do leite materno antes dos seis meses de idade associa-se com diminuição dos níveis médios de hemoglobina. A alta prevalência de anemia e o baixo percentual de crianças em aleitamento materno exclusivo chamam atenção para a necessidade do controle dessa deficiência nutricional no município e para a promoção do aleitamento materno exclusivo até os seis meses.Núcleo de Editoração – PUC-Campinas2023-09-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9662Brazilian Journal of Nutrition; Vol. 20 No. 2 (2007): Revista de NutriçãoRevista de Nutrição; Vol. 20 Núm. 2 (2007): Revista de NutriçãoRevista de Nutrição; v. 20 n. 2 (2007): 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/9662/7013Copyright (c) 2023 Luciane Simões DUARTE, Elizabeth FUJIMORI, Aurea Tamami MINAGAWA, Flavia Antonini SCHOEPS, Rosali Maria Juliano Marcondes MONTEROhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Simões DUARTE, Luciane FUJIMORI, ElizabethTamami MINAGAWA, Aurea SCHOEPS, Flavia AntoniniMarcondes MONTERO, Rosali Maria Juliano 2023-10-05T18:43:57Zoai:ojs.periodicos.puc-campinas.edu.br:article/9662Revistahttp://www.scielo.br/rnPRIhttps://periodicos.puc-campinas.edu.br/nutricao/oai||sbi.submissionrn@puc-campinas.edu.br1678-98651415-5273opendoar:2023-10-05T18:43:57Revista de Nutrição - Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)false |
