Resumo: During adolescence, the risk of development of iron-deficiency anemia is higher because of the growth spurt and the sexual maturation which increase the iron requirement. One hundred and thirty adolescents (males and females) were studied, in order to assess the serum hemoglobin values in different sexual maturation stages. The photometric method was used and a self-evaluation of the sexual maturation stage based on Tanner´s criteria was applied. The average hemoglobin values were similar for both sexes, as well for girls who had menstruated or not. The average hemoglobin values were 13.3 (s.d. 1.12)g/dL for males and 13.3 (s.d.0.83)g/dL for females (p=0.64). Among the studied adolescents, 7.7% had iron-deficiency anemia. Due to the iron requirement increase during the growth spurt, mainly in females, and the higher susceptibility to iron deficiency anemia, special attention to the adolescents is recommended.

Estudaram-se 130 adolescentes, de ambos os sexos, para verificar os valores de hemoglobina sérica em diferentes fases de maturação sexual. Utilizou-se o método de fotometria para dosar a hemoglobina sérica e realizou-se auto-avaliação do estágio de maturação sexual com base nos critérios de Tanner. Os níveis médios de hemoglobina foram semelhantes entre sexos, bem como entre meninas que menstruavam ou não. O nível médio de hemoglobina foi de 13,3g/dL tanto para os meninos como para as meninas (p=0,64), com desvios-padrão de 1,12 e de 0,83, respectivamente. Entre os adolescentes estudados, 7,7% tinham anemia ferropriva. Recomenda-se atenção ao grupo de adolescentes, devido ao aumento da necessidade de ferro durante o estirão de crescimento, principalmente entre as meninas, aumentando a suscetibilidade à anemia. Núcleo de Editoração – PUC-Campinas2003-06-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9126Brazilian Journal of Nutrition; Vol. 16 No. 2 (2003): Revista de NutriçãoRevista de Nutrição; Vol. 16 Núm. 2 (2003): Revista de NutriçãoRevista de Nutrição; v. 16 n. 2 (2003): 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/9126/6510Copyright (c) 2023 Maria Fernanda Petroli FRUTUOSO, Vanessa Alves VIGANTZKY, Ana Maria Dianezi GAMBARDELLAhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPetroli FRUTUOSO, Maria Fernanda Alves VIGANTZKY, VanessaDianezi GAMBARDELLA, Ana Maria 2024-04-08T14:11:15Zoai:ojs.periodicos.puc-campinas.edu.br:article/9126Revistahttp://www.scielo.br/rnPRIhttps://periodicos.puc-campinas.edu.br/nutricao/oai||sbi.submissionrn@puc-campinas.edu.br1678-98651415-5273opendoar:2024-04-08T14:11:15Revista de Nutrição - Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)false
