RESUMO

OBJETIVOS:

descrever as freqüências de anemia e ferropenia em gestantes de baixo risco, de acordo com a ferritina sérica e diferentes pontos de corte da concentração de hemoglobina (Hb).

MÉTODOS:

estudo transversal, utilizando-se banco de dados com 318 gestantes atendidas no período de maio de 2000 a junho de 2001, no Instituto Materno Infantil Prof. Fernando Figueira-IMIP, em Recife, Pernambuco. Determinou-se a freqüência de anemia e/ou ferropenia em função da ferritina e dois diferentes pontos de corte da Hb (11,0 e 10,5g/dL). Os dados foram analisados nos programas Epi-Info 6.04b e Minitab v.14.2. O projeto foi aprovado pelo Comitê de Ética em Pesquisa do IMIP.

RESULTADOS:

as freqüências de anemia (Hb<11,0g/dL) e anemia ferropriva (Hb<11,0g/dL; ferritina<12ng/mL) foram 56,6 por cento e 10,7 por cento, respectivamente. Mudando o ponto de corte da Hb (<10,5g/dL), a freqüência de anemia foi reduzida para 37,4 por cento e de anemia ferropriva para 7,9 por cento. Os valores de ferritina sérica foram maiores nas anêmicas do que nas não anêmicas, independente do ponto de corte de Hb considerado na definição da anemia.

CONCLUSÕES:

a freqüência de anemia na amostra foi compatível com o esperado, porém, a proporção de anemia ferropriva foi muito aquém. Os valores de ferritina se comportaram de maneira inversa ao que teoricamente, era esperado.
ABSTRACT

OBJECTIVES:

to describe the frequency of anemia and iron deficiency anemia, using two cutoff points for hemoglobin concentration (Hb) as well as serum ferritin levels in women with low-risk pregnancies.

METHODS:

a cross-sectional study was carried out based on the database records of 318 pregnant women at the Instituto Materno Infantil Professor Fernando Figueira-IMIP, in the city of Recife, State of Pernambuco, Brazil, between May 2000 and June 2001. The frequency of anemia and/or iron deficiency anemia were determined using two Hb cutoff points (<11.0 and <10.5g/dL) in addition to serum ferritin levels. Data were analyzed using the Epi-Info 6.04b and Minitab v.14.2 software programs. The project was approved by the Research Ethics Committee.

RESULTS:

the frequency of anemia (Hb<11.0g/dL) and the frequency of iron deficiency anemia (Hb<11.0g/dL; ferritin<12ng/mL) were 56.6 percent and 10.7 percent, respectively. When the Hb cutoff point was changed to 10.5g/dL, the frequency of anemia fell to 37.4 percent and the frequency of iron deficiency anemia to 7.9 percent. Higher serum ferritin levels were found in anemic patients than in non-anemic patients, regardless of the Hb cutoff point used.

CONCLUSIONS:

the frequency of anemia was acceptable, but the proportion of iron deficiency anemia was far lower than expected. Ferritin levels seemed to behave in a way that contradicts the theoretical literature on the subject.
