Abstract
Determinar a prevalência de deficiência de ferro e fatores associados em lactentes. Neste estudo transversal, foram estudados 365 lactentes atendidos em um centro de saúde-escola, em Belém, Pará, Brasil. Anemia ferropriva (hemoglobina < 11g/dl e ferritina < 12µg/l) foi caracterizada em 55,1% dos 365 lactentes; depleção das reservas corporais de ferro (hemoglobina > 11g/dl e ferritina < 12µg/l), em 15,3%; e suficiência em ferro (hemoglobina > 11g/dl e ferritina > 12µg/l), em 18,1%. Em 12,5% dos lactentes, não incluídos na avaliação dos fatores associados com a deficiência de ferro, encontraram-se hemoglobina < 11,0g/dl e ferritina > 12µg/l. Os resultados do modelo de regressão logística mostraram associação entre deficiência de ferro (ferritina < 12µg/l) e: faixa etária entre 6 e 12 meses, OR = 3,67 e IC95%: 1,93-7,04; não utilização de fórmula fortificada com ferro como primeiro leite no desmame, OR = 1,93 e IC95%: 1,04-3,60; e renda per capita ¾ 1 salário mínimo, OR = 2,69 e IC95%: 1,30-5,59. A prevalência de deficiência de ferro foi elevada, evidenciando a necessidade de implementação de ações efetivas para a prevenção desse importante problema de saúde pública.
The objective was to verify the occurrence of iron deficiency and associated factors in infants. This cross-sectional study included 365 infants (defined here as 6-24 months of age) treated at a primary care center in Belém, Pará, Brazil. Iron-deficiency anemia (hemoglobin < 11g/dl and ferritin < 12µg/l) was diagnosed in 55.1% of the sample, depletion of body iron reserves (hemoglobin < 11g/dl and ferritin < 12µg/l) in 15.3%, and iron sufficiency (hemoglobin < 11g/dl and ferritin < 12µg/l) in 18.1%. The results of the logistic regression model showed associations between iron deficiency (ferritin < 12µg/l) and: 6-12 month age group, OR (odds ratio) = 3.67 and 95% CI: 1.93-7.04; non-utilization of iron-fortified formula as the first milk used after interrupting breastfeeding, OR = 1.93 and 95%CI: 1.04-3.60; and per capita income ¾ 1 minimum wage, OR = 2.69 and 95%CI: 1.30-5.59. The occurrence of iron deficiency was high, showing the need to adopt effective measures to prevent this important public health problem.
