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.

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. Resumo Fundamento: A pré-eclâmpsia tem sido associada a vários fatores de risco e eventos. No entanto, esta doença é merecedora de mais investigações, tendo em vista a multiplicidade de fatores relacionados que acometem diferentes populações. Objetivo: Avaliar os fatores maternos e os resultados perinatais adversos em uma coorte de gestantes com pré-eclâmpsia da rede pública de saúde de Maceió. Métodos: Estudo de coorte prospectivo realizado em 2014 na rede pública de saúde do município com uma amostra de gestantes calculada com base na prevalência de pré-eclâmpsia de 17%, nível de confiança de 90%, poder de 80% e razão de 1:1. Foi aplicado um questionário para coleta de dados socioeconômicos, pessoais e antropométricos, e obtidas variáveis perinatais de prontuário e da declaração de nascido vivo. Análise realizada com regressão de Poisson e teste do qui-quadrado, considerando p < 0,05 como significativo. Resultados: Foram estudadas 90 gestantes com pré-eclâmpsia (GCP) e 90 gestantes sem pré-eclâmpsia (GSP). História prévia de pré-eclâmpsia (razão de prevalência [RP] = 1,57, intervalo de confiança de 95% [IC 95%] 1,47-1,67, p = 0,000) e cor da pele negra (RP = 1,15, IC 95% 1,00-1,33, p = 0,040) estiveram associadas à ocorrência de pré-eclâmpsia. Entre os recém-nascidos das GCP e GSP, 12,5% e 13,1%, respectivamente, eram pequenos para a idade gestacional (p = 0,907) e 25,0% e 23,2%, respectivamente, eram grandes para a idade gestacional (p = 0,994). Houve predomínio da via de parto cesariana. Conclusão: História pessoal de pré-eclâmpsia e cor da pele negra estiveram associadas à ocorrência de pré-eclâmpsia. Houve elevadas frequências de desvios de peso ao nascer e da via de parto cesariana.

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
