Resumo: Introdução e objetivo: O estresse oxidativo é uma provável via crítica na patogênese da pré‐eclâmpsia. Evidências têm sugerido que o consumo adequado de antioxidantes é capaz de modular essa condição. Assim, o objetivo da presente pesquisa foi avaliar a ingestão e o coeficiente de variabilidade de nutrientes antioxidantes por gestantes com pré‐eclâmpsia (GCP). Métodos: Estudo transversal realizado na rede pública de saúde do município de Maceió através de inquérito dietético, com aplicação de: recordatórios alimentares de 24 horas, com posteriores ajustes dos nutrientes pelo método da EAR como ponto de corte, e questionário de frequência de consumo de antioxidantes. Resultados: Foram estudadas 90 GCP e 90 gestantes sem pré‐eclâmpsia (GSP), com médias de idade de 25,8 ± 6,7 anos e 24,1 ± 6,2 anos (p = 0,519), respectivamente. Foram observadas baixas médias de consumo de antioxidantes (vitamina A, selênio, zinco e cobre) para GCP e GSP, apesar do maior consumo de vitamina A (p = 0,045) e selênio (p = 0,008) pelas GSP. Adicionalmente, foram observados elevados coeficientes de variabilidade de consumo para ambos os grupos (GCP versus GSP, respectivamente); no entanto, maiores para as GCP de vitamina C (p

Abstract Background: Preeclampsia has been associated with several risk factors and events. However, it still deserves further investigation, considering the multitude of related factors that affect different populations. Objective: To evaluate the maternal factors and adverse perinatal outcomes in a cohort of pregnant women with preeclampsia receiving care in the public health network of the city of Maceió. Methods: Prospective cohort study carried out in 2014 in the public health network of the city with a sample of pregnant women calculated based on a prevalence of preeclampsia of 17%, confidence level of 90%, power of 80%, and ratio of 1:1. We applied a questionnaire to collect socioeconomic, personal, and anthropometric data, and retrieved perinatal variables from medical records and certificates of live birth. The analysis was performed with Poisson regression and chi-square test considering p values < 0.05 as significant. Results: We evaluated 90 pregnant women with preeclampsia (PWP) and 90 pregnant women without preeclampsia (PWoP). A previous history of preeclampsia (prevalence ratio [PR] = 1.57, 95% confidence interval [95% CI] 1.47 - 1.67, p = 0.000) and black skin color (PR = 1.15, 95% CI 1.00 - 1.33, p = 0.040) were associated with the occurrence of preeclampsia. Among the newborns of PWP and PWoP, respectively, 12.5% and 13.1% (p = 0.907) were small for gestational age and 25.0% and 23.2% (p = 0.994) were large for gestational age. There was a predominance of cesarean delivery. Conclusion: Personal history of preeclampsia and black skin color were associated with the occurrence of preeclampsia. There was a high frequency of birth weight deviations and cesarean deliveries.
