Resumo O objetivo deste artigo é avaliar a insegurança alimentar e os seus fatores associados em gestantes atendidas pela rede pública de saúde de uma capital do nordeste brasileiro. Estudo transversal, realizado com gestantes que residiam em Maceió, e que eram atendidas pela rede pública de saúde municipal, das quais foram coletados dados socioeconômicos, antropométricos e realizadas medidas de hemoglobina e glicemia capilar e aferição da pressão arterial. A insegurança alimentar foi avaliada através da Escala Brasileira de Insegurança Alimentar e sua associação com os fatores de risco foi testada por meio de análise de regressão de Poisson, com os resultados expressos pela Razão de Prevalência e Intervalo de Confiança de 95%. Foram analisadas 363 gestantes, com prevalência de insegurança alimentar de 42,7%, sendo 8,0% delas em insegurança grave. Houve associação da insegurança alimentar com: hiperglicemia materna e níveis pressóricos maternos elevados. Foi elevada a prevalência de insegurança alimentar em gestantes atendidas pela rede pública de saúde de uma capital do nordeste brasileiro, estando associada à hiperglicemia materna e a níveis pressóricos elevados. Os resultados precisam ser vistos para que sejam realizadas mais ações que garantam o direito à alimentação adequada a essa população. Abstract The scope of this article is to evaluate food insecurity and its associated factors among pregnant women attended in the public health network of a northeastern Brazilian capital. It is a cross-sectional study with pregnant women living in the capital of the State of Maceió who were attended by the public municipal health network, from which socioeconomic, anthropometric and hemoglobin and blood glucose and blood pressure measurement data were collected. Food insecurity was assessed using the Brazilian Food Insecurity Scale and its association with the risk factors was tested using Poisson regression analysis, with the results assessed using the Prevalence Ratio and 95% Confidence Interval. Analysis was conducted on 363 pregnant women with a prevalence of food insecurity of 42.7%, of which 8% had severe insecurity. There was an association of food insecurity with maternal hyperglycemia and high maternal blood pressure levels. The prevalence of food insecurity was high among pregnant women attended in the public health network of a northeastern Brazilian capital, being associated with maternal hyperglycemia and high blood pressure. The results should be studied such that more actions are implemented to ensure the right to adequate food for this population group.

Introduction and Objective: 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. Methods: 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. Results: 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
