Childhood anemia prevalence and associated factors in Salvador, Bahia, Brazil

Abstract: A cross-sectional study was conducted in 1996 to estimate the prevalence of anemia in a stratified sample of 603 preschool children and identify factors associated with the disease. Hemoglobin assays were conducted in finger-prick blood samples using a Hemocue hemoglobinometer. Anemia was defined as hemoglobin below 11.0 g/dl. Logistic regression analysis was used to evaluate the potential associations. Observed anemia prevalence was 46.3%. Associated factors were: the 6-12-month and 12-24-month age brackets, … Show more

“…Studies conducted among preschool children in northeastern Brazil have reinforced this relationship. 2,21 In the rural area, anemia did not present a statistical association with lack of treatment for drinking water and lack of sewage treatment. However, 74% of the children in the rural area were living in households that were not using treated water for drinking, and 57% did not have adequate sewage systems in their homes.…”

“…Em doze estudos, 14,15,[17][18][19][20][21]23,25,27,29,30 foi utilizado o ponto de corte indicado pela Organização Mundial da Saúde 1,2 para o diagnóstico da anemia (Hb<11g/dL, para crianças de 6-59 meses), entretanto, um dos estudos internacionais 26 utilizou o ponto de corte da hemoglobina <10g/dL. Em relação à deficiência de ferro, nenhum estudo brasileiro avaliou esta deficiência e os estudos estrangeiros que o fizeram, utilizaram dois ou mais parâmetros associados, como ferritina, saturação da transferrina, protoporfirina eritrocitária livre, zincoprotoporfirina e volume corpuscular médio.…”

“…Assim, não é simples explicar os fatores determinantes da anemia e fazer uma análise generalizada sobre a contribuição específica de cada determinante no aparecimento da anemia, limitando a validade externa desses estudos. [14][15][16][17][18][19][20][21][24][25][26] Pode-se ainda considerar limitante o fato de que os artigos aqui analisados são estudos transversais, os quais além de estarem sujeitos a vários vieses, permitem observar apenas associações entre os eventos, impossibilitando determinar a relação de causa e efeito entre estes. Outra limitação da presente revisão foi a utilização apenas dos artigos em inglês ou português, o que impossibilitou o acesso a alguns resultados originados de revistas publicadas em outros idiomas.…”
