Associação entre anemia durante a gestação e parto prétermo: estudo de Coorte NISAMI

Abstract

This study aimed to investigate the association between maternal anemia and preterm delivery in pregnant women enrolled in prenatal care from public, the municipality of Santo Antônio de Jesus / BA. This is a prospective cohort study. The cutoff for anemia was hemoglobin <11g / dL and preterm delivery, gestational age ≤ 37 weeks. The chisquare test for dichotomous variables were applied. To verify the association of anemia with prematurity was held on logistic regression analysis. The results suggest that anemia in pregnancy increases the risk of preterm (RR = 2.14; CI: 1.24 to 3.68) birth. It was also observed that single women (RR = 2.25; CI: 1.28 to 3.95), with income between 2-4 minimum wages (RR = 2.02; CI: 1.22 to 3.33 ), have an increased risk of prematurity, while the overweight offers a protection factor for this event (RR = 0.41; CI: 0.21 to 0.82). Anemia in pregnancy showed a positive and statistically significant association with increased risk of preterm birth, both in crude analysis and after adjustment. The orientation of measures aimed at reducing risk factors, preventive approach to control anemia in pregnancy is needed.th a preventive approach to control anemia in pregnancy is needed.
