Abstrakt: Objective: To determine the prevalence of anemia among pregnant women and the associated factors and perinatal outcomes according to two different diagnostic criteria: the WHO criterion and the US Center for Disease Control and Prevention (CDC) criterion.
Methods: Cohort study, operationalized through a database. The sample comprised 781 pregnant women who had laboratory data regarding hemoglobin levels during the second trimester of pregnancy. Anemia was diagnosed when hemoglobin was less than 11 g/dl according to WHO and less than 10.5 g/dl according to CDC. Factors possibly associated with anemia were identified by adjusting Poisson univariate and multivariate regression models. To analyze the association between perinatal outcomes and anemia, the χ 2 test and Fisher exact test were performed.
Results: The prevalence of anemia was 22.9% according to WHO and 10.9% according to CDC. A significantly higher risk of low birth weight was found in children of women with anemia, regardless of the diagnostic criteria used, while a greater risk of having a small-for-gestational-age newborn was seen only when the CDC criterion were applied.
Conclusion: Anemia during pregnancy remains an important public health issue, but its magnitude may be overestimated by overly sensitive assessment criteria.
