Distribuição da anemia em pré-escolares do semi-árido da Bahia Distribution of anemia among preschool children from the semi-arid region of Bahia

Abstract

O objetivo desta investigação foi identificar a prevalência da anemia e alguns de seus potenciais determinantes em 754 crianças de áreas urbanas de sete municípios na região do semi-árido baiano. Hemoglobina foi determinada em 745 crianças de um a 72 meses de idade. Para o grupo etário de seis a 72 meses um valor de hemoglobina The objective of this survey was to determine the prevalence of anemia and potential determinants thereof in 754 children from urban areas of seven small towns in the semi-arid region of Bahia. Hemoglobin was measured in 745 children 1 to 72 months of age. For the 6-to-72 month-old group, hemoglobin < 11.0 g/dl was considered anemia (following WHO recommendations) whereas <9.5 g/dl was considered severe anemia. The same cutoffs were used for children under 6 months, which are the same ones used in clinical-hematology. A mean hemoglobin of 12.1 g/dl was found, distributed differently according to age groups (p=0.001). The study found prevalences of 22.2 % for anemia and 5.8% for severe anemia, respectively. Occurrence of anemia varied significantly with age (p=0.001); the highest prevalence was 50.0% in children 12 to 23 months of age, followed by 29.9% in children below 12 months. The association of anemia with mother's education (controlled for age) and per capita family income was not statistically significant.
