To evaluate the factors associated with anemia among pregnant women receiving public health care in a capital city in Northeastern Brazil.
This was a cross-sectional study conducted on a sample of 428 patients obtained on the basis of the estimated prevalence of anemia during pregnancy (50%), a 95% confidence interval (95%CI), an error of 5% and a sample loss of 20%. Pregnant women who lived in the city and were served by the municipal public health network were considered to be eligible for the study. Socioeconomic, lifestyle, clinical and anthropometric data and dietary iron intake were obtained, and capillary hemoglobin was determined. Anemia was identified as a hemoglobin level <11 g/dL, and its association with risk factors was tested using multivariate Poisson regression analysis, with the results expressed as the Prevalence Ratio (PR) and 95%CI.
The prevalence of anemia was 28.3% and was higher among women with more members in the household (PR=1.49; 95%CI 1.01-2.22; p=0.046) and those living with food insecurity (PR=1.43; 95%CI 1.00-2.04; p=0.047).
The prevalence of anemia among pregnant women receiving care from the public health system of the city is a moderate public health problem, requiring the planning of effective measures for its control.
