| description | Oxidative stress appears to play a critical role in the pathogenesis of preeclampsia. Evidence suggests that adequate intake of antioxidants can modulate this condition. The objective of this study was to assess the intake of antioxidant nutrients and coefficients of variation in pregnant women with preeclampsia.
In a cross-sectional study in the public health network of the city of Maceió, Brazil, a dietary survey was performed consisting of 24-hour food recalls, with subsequent adjustment of nutrients using the estimated average requirement as the cutoff point, and a questionnaire on frequency of consumption of antioxidants.
We studied 90 pregnant women with preeclampsia (PWP) and 90 pregnant women without preeclampsia (PWoP) with mean ages of 25.8±6.7 years and 24.1±6.2 years (p=0.519), respectively. A low mean intake of antioxidants (vitamin A, selenium, zinc and copper) was observed in both PWP and PWoP, although intakes of vitamin A (p=0.045) and selenium (p=0.008) were higher in PWoP. In addition, we observed high coefficients of variation in nutrient intakes in both groups, which were higher for vitamin C (p |

Consumption of antioxidant nutrients by pregnant women with preeclampsia is inadequate, with considerable daily variations in intake, which points to a need for nutrition education strategies aimed at improving intakes, because diet is without doubt a key factor in the modulation of oxidative stress caused by preeclampsia.</description><identifier>EISSN: 2174-2030</identifier><identifier>DOI: 10.1016/j.repc.2016.03.005</identifier><identifier>PMID: 27503592</identifier><language>eng ; por</language><publisher>Portugal</publisher><subject><![CDATA[Adult ; Antioxidants - administration & dosage ; Brazil ; Copper - administration & dosage ; Cross-Sectional Studies ; Diet Surveys ; Female ; Humans ; Oxidative Stress - drug effects ; Pre-Eclampsia - metabolism ; Pregnancy ; Selenium - administration & dosage ; Vitamin A - administration & dosage ; Vitamins - administration & dosage ; Young Adult ; Zinc - administration & dosage]]></subject><ispartof>Revista portuguesa de cardiologia, 2016-09, Vol.35 (9), p.469-476</ispartof><rights>Copyright © 2016 Sociedade Portuguesa de Cardiologia.
