Deficiência de ferro em gestantes e seus fatores associados no município de Santo Antônio de Jesus - BA

Abstract

Iron deficiency is characterized by imbalance in the balance between the amount of this bioavailable mineral absorbed in the diet and the need for the organism. During the gestational period, this event can be facilitated, both by the expansion of the blood volume, and by the increase of the iron demand due to the needs formation and growth of the fetus. Objective: To evaluate the prevalence of iron deficiency (independent of hemoglobin dosage) by means of serum ferritin dosage in pregnant women who underwent prenatal follow-up at the basic health units of the city of Santo Antônio de Jesus-BA. Materials and methods: A cross-sectional, analytical study composed of pregnant women who performed prenatal care at a family health unit in the city of Santo Antônio de Jesus -Bahia - Brazil. The study was approved by the Research Ethics Committee of the State University of Feira de Santana under CAAE registration 0176.0.059.000-1, according to Resolution 466/12 of the National Health Council (CNS). Results: The sample consisted of 747 women. It was observed that 15.26% of the study participants were diagnosed with iron deficiency. Among the variables studied, there was a statistically significant association with the outcome, unpaid occupation (RP: 2.15, 95% CI: 1.46-3.17), number of people in the household (RP 1.77, 95% CI: 1.26-2.48) and number of prenatal visits (PR: 0.49, 95% CI: 0.32-0.75). Conclusion: Considering that gestation is a period that favors the development of iron deficiency, we emphasize the importance of quality prenatal consultation, combined with a multiprofessional team.
