Abstract

Anemia em alunos de escolas públicas no Recife: um estudo de tendências temporaisAnemia in students at public schools in Recife: a study of temporal trends (2001)(2002)(2003)(2004)(2005). Palavras-chave Anemia, Saúde escolar, Estudos transversaisAbstract The scope of this study was to evaluate trends in the temporal evolution of anemia in students ranging from the ages of 7 to 11 in Várzea district (Recife-PE) based on three reports concluded in 1982, 2001 and 2005. An evaluation was achieved in ten public schools in the first study and nine in the last two (one was shut down), in a sample of 305 students (1982), 684 students (2001) and 756 students (2005). Hemoglobin was determined in blood samples taken by venopunction, having two criteria to describe anemia: cut points < 12 g/dL and < 11.5 g/dL. By the first criteria, the prevalence of anemia increased from 8.8% in 1982 to 18.9% in 2001, decreasing to 13.4% in 2005. In the last evaluation, the problem of anemia practically disappeared starting from the age of 9. The evolution of anemia revealed two very different trends: marked elevation in the first phase (1982 to 2001) and a rapid decrease in the second stage (2001 to 2005).

Comparative analysis of anemia in children from public and private schools and their determining factors in Santarém-PA

“…Do total desta amostra, apenas 5,3% apresentaram anemia leve, ou seja, índice entre 10 e 11,5 g/dl, e 94,7% tiveram valores dentro da normalidade. No estudo de Lemos et al (2011), a prevalência de anemia leve foi de 3,6%, concordando com os resultados desta pesquisa aonde a maioria dos estudantes de escola pública apresentam índices de hemoglobina adequados. Em contrapartida, a análise dos exames das crianças da rede de ensino privado demonstrou valor médio de hemoglobina de 12,4 g/dl, sendo o valor mínimo encontrado de 11,2 g/dl.…”

Iron intake and its association with iron-deficiency anemia in agricultural workers' families from the Zona da Mata of Pernambuco, Brazil

“…There are only a few studies on the prevalence of anemia in other population groups [20][21][22] . Studies of anemia in children and adolescents aged 6 to 18 years enrolled in public schools found prevalences of 3.6% in 2005 in Recife (PE) to 39.3% in 2008 in Maringá (PR) 21,22 .…”
