SUMMARY:

The aim of this study was to investigate the degree of association between the dietary total antioxidant capacity (TAC) of pregnant women and maternal-fetal outcomes. Cross-sectional study, carried out between 2013/2014, with pregnant women assisted in the basic health units (BHUs) belonging to the local public health system of Maceió City, Alagoas State. Pregnant women with a single fetus who lived in Maceió and were assisted in the BHUs were included; and those who had physical changes that could distort the anthropometric assessment and/or neurological problems were excluded. Socioeconomic, demographic, clinical, anthropometric and dietary data were collected and maternal-fetal outcomes of interest were collected after birth. To calculate and determine dietary TAC, the following were analyzed: the ferric reducing capacity of plasma (FRAP) and the oxygen radical absorption capacity (ORAC), including ORAC-total and total phenolics (TP). Pearson's χ2 and Fisher's exact χ2 statistical tests were performed to determine differences in maternal and neonatal outcomes in tertiles (T1, T2 and T3) of dietary TAC adjusted for energy using the residual method, adopting a significance of p<0.05. The project was approved by the Ethics and Research Committee of the Federal University of Alagoas under CAAE no. 18807113.3.0000.5013. In the adjusted model, the higher risk of gestational obesity in T1 of FRAP and the higher occurrence of vaginal birth in T2 of FRAP remained significant; the higher risk of gestational overweight, prematurity, fewer full-term births and appropriate for gestational age (AGA) in T1 of TP and higher probability of full-term birth in T2 of TP; higher chance of arterial hypertension, low birth weight (LBW), newborn small for gestational age (SGA), large for gestational age (LGA) and less AGA in T1 of ORAC-total, lower risk of premature birth and more than term at T2 of ORAC-total and higher possibility of low gestational weight at T3 of ORAC-total. The foods that most contributed to the consumption of FRAP in this population were coffee (with and without milk), fruits and fruit juices (guava, orange and apple) and couscous. While the biggest influences on TP consumption were couscous, fruits and fruit juices (guava and apple), chocolate and soups (bean and vegetable). The ORAC-total, in turn, had fruits and fruit juices (mango, guava, apple and orange), cereals (rice and couscous) and soups (beans and vegetables) as the most active foods. Finally, pregnant women in the lowest tertile of dietary TAC had a higher risk of negative maternal-fetal outcomes, unlike those in the highest tertiles. This provides evidence that dietary consumption of total antioxidants can have beneficial effects on maternal-fetal health and be used in clinical practice to prevent such outcomes.
