Biomarkers of placental redox imbalance in pregnancies with preeclampsia and consequent perinatal outcomes.

OBJECTIVE: To compare redox and inflammatory markers between normal and PE-derived placentas and to evaluate the relationship between placental redox imbalance markers and perinatal outcomes in pregnancies with PE. METHODS: This was a cross-sectional study conducted at the maternity hospital of a university hospital in Maceio-Alagoas, Brazil, in 2017, including women diagnosed with PE and healthy pregnant women and their conceptuses. After screening, standardized questionnaires containing socioeconomic, clinical, obstetric and anthropometric data were applied. After delivery, placental samples were collected for quantification of biomarkers of redox imbalance (catalase - CAT; malondialdehyde - MDA; hydrogen peroxide - H2O2; superoxide dismutase - SOD; reduced glutathione - GSH; oxidized glutathione - GSSG; and their ratio - GSH/GSSG) and inflammation (myeloperoxidase - MPO; interleukin (IL)-6; IL-8; IL-10; and tumor necrosis factor-alpha - TNF-α). All biomarkers were evaluated via linear regression with adjustments of variables with measures of weight, length, head circumference (HC), chest circumference (CC) and gestational age of newborns at birth, considering p < 0.05 as significant. RESULTS: A total of 100 pregnant women with PE and 50 healthy pregnant women were studied. Higher placental levels of catalase (p = 0.018), SOD (p = 0.031), the GSH/GSSG ratio (p = 0.019) and IL-6 (p = 0.010) and lower GSSG (p = 0.001) were observed in pregnant women with PE than in the control group. Positive associations between placental GSH levels and body weight, HC, CC and gestational age at birth (p < 0.05) were identified. CONCLUSION: PE-derived placentas had high concentrations of some antioxidants (enzymes and thiols), which might be a compensation mechanism against oxidative stress. Placental GSH levels were the only biomarker, among the studied ones, related positively with beneficial perinatal outcomes, suggesting that this endogenous antioxidant plays an important role in maintaining the health of the conceptus and women with PE.

Association between being underweight and excess body weight before SARS coronavirus type 2 infection and clinical outcomes of coronavirus disease 2019: Multicenter study.

OBJECTIVES: The present study aimed to identify associations between extremes in body weight status (underweight and excess body weight) before a COVID-19 diagnosis and clinical outcomes in patients infected with SARS coronavirus type 2. METHODS: A multicenter cohort study was conducted in eight different states in northeastern Brazil. Demographic, clinical (previous diagnosis of comorbidities), and anthropometric (self-reported weight and height) data about individuals who tested positive for COVID-19 were collected. Outcomes included hospitalization, mechanical ventilation, and death. Multivariable logistic regression models, adjusted based on age, sex and previous comorbidities, were used to assess the effects of extremes in body weight status on clinical outcomes. RESULTS: A total of 1308 individuals were assessed (33.6% were elderly individuals). The univariable analyses showed that only hospitalization was more often observed among underweight (3.2% versus 1.2%) and overweight (68.1% versus 63.3%) individuals. In turn, cardiovascular diseases were more often observed in all clinical outcomes (hospitalization: 19.7% versus 4.8%; mechanical ventilation: 19.9% versus 13.5%; death: 21.8% versus 14.1%). Based on the multivariable analysis, body weight status was not associated with risk of hospitalization (underweight: odds ratio [OR]: 1.10; 95% confidence interval [CI] 95%, 0.50-2.41 and excess body weight: OR: 0.81; 95 CI, 0.57-1.14), mechanical ventilation (underweight: OR: 0.92; 95% CI, 0.52-1.62 and excess weight: OR: 0.90; 95% CI, 0.67-1.19), and death (underweight: OR: 0.61; 95% CI, 0.31-1.20 and excess body weight: OR 0.88; 95% CI, 0.63-1.23). CONCLUSIONS: Being underweight and excess body weight were not independently associated with clinical outcomes in patients with COVID-19 in the herein analyzed cohort. This finding indicates that the association between these variables may be confounded by both age and comorbidities.

Biomarkers of Inflammation and Redox Imbalance in Umbilical Cord in Pregnancies with and without Preeclampsia and Consequent Perinatal Outcomes.

OBJECTIVE: To compare redox imbalance and inflammation biomarkers in umbilical cords from pregnancies with and without preeclampsia (PE) and to analyse their relationships with perinatal outcomes. METHODS: A controlled cross-sectional study was conducted in Maceió, Alagoas, Brazil, that involved pregnant women with PE and a group of women without the disease, through the application of a standardized questionnaire. After delivery, umbilical cord samples were collected to measure antioxidant defense, products from oxidative damage, and inflammation biomarkers such as myeloperoxidase (MPO), interleukin- (IL-) 6, IL-8, IL-10, and tumor necrosis factor-alpha (TNF-α). Statistical analyses were performed using Stata version 13.0 software and IBM Statistical Package for the Social Sciences (SPSS) 20.0, adopting a 95% confidence level (α = 0.05), with the chi-square test, the Wilcoxon-Mann-Whitney test, and the multinomial and Poisson regression tests. RESULTS: One hundred PE pregnant women and 50 women without the disease were studied. The umbilical cords from PE pregnancies showed higher levels of reduced glutathione (GSH) (p ≤ 0.001), glutathione peroxidase (GPx) (p = 0.016), and malondialdehyde (MDA) (p = 0.028) and lower levels of IL-6 (p = 0.030) and TNF-α (p ≤ 0.001) than the other group, with some associations among these biomarkers with perinatal outcomes. CONCLUSION: The higher levels of GSH and GPx, in addition to the lower levels of IL-6 and TNF-α, found in the PE umbilical cord, may result from adaptive mechanisms to maintain the oxidative and inflammatory balance; however, despite these changes, the damage to the cell membranes was not minimized, as the MDA level was higher in women with PE than in women without the disease. This implies that a redox imbalance is present, confirming that other physiological and adaptive mechanisms are being activated to preserve foetal health. Therefore, the present work unveils an important role of the umbilical cord in controlling redox imbalance and inflammation in PE pregnancies. Our results reinforce the necessity for continuous research on GSH as a protective compound for the perinatal outcome, especially in PE women.

Associated factors with excessive weight gain in pregnant women from Maceió, Northeastern Brazil.

This article aims to evaluate the associated factors with excessive weight gain in pregnant women from Maceió, the capital of Alagoas, Northeastern Brazil. Cross-sectional study with pregnant women attended in public health in the city of Maceió in 2014, of which socioeconomic, clinical (glycemia, capillary hemoglobin, and blood pressure measurement), dietary, and anthropometric data, including in the latter gestational weight gain, classified as insufficient, adequate and excessive according to the US Institute of Medicine, were collected. The combination of excessive weight gain with the independent variables was tested using the Poisson regression expressed by the Prevalence Ratio (PR) and a 95% confidence interval (CI95%). We studied 403 pregnant women with a mean age of 24.08 ± 6.01 years, with 19.9% of them displayed insufficient weight gain; 14.1% displayed adequate weight gain, and 66.0% displayed excessive weight gain, that was associated with maternal hyperglycemia (PR = 1.35; CI95% = 1.17 to 1.57; p < 0.001). Excessive weight gain is common among pregnant women evaluated with the association of this variable with maternal hyperglycemia.

Oxidative stress markers in preeclamptic placentas: A systematic review with meta-analysis.

INTRODUCTION: Oxidative stress (OS) is the basis of several diseases. Preeclampsia (PE) is a multisystemic syndrome, considered one of the major causes of maternal and fetal mortality. The placenta is considered the main anatomical pathogenetic substrate for the disease, being the placental OS a likely critical pathway in the pathogenesis of PE. This meta-analysis aimed to verify whether there is OS in the preeclamptic placenta and which markers are altered in this condition. METHODS: The search was conducted in the following databases: MEDLINE (via PubMed), Lilacs and Scopus. Relevant studies were identified until May 2020. The quality of the studies was evaluated according to the Newcastle-Ottawa scale. RESULTS: From the 3998 screened records, 43 were finally included in the systematic review, and 23 in the meta-analysis. The biomarkers evaluated were related to cell and macromolecules' damage, such as malondialdehyde (MDA), 8-hydroxy-2'-deoxyguanosine (8-OH-dG), lipid peroxides, isoprostane, total oxidant status (TOS), carbonylated proteins and some of the reactive oxygen and nitrogen species (RONS), like hydrogen peroxide and nitric oxide. It was also related to antioxidant activity, both enzymatic, including superoxide dismutase (SOD), catalase, glutathione peroxidase (GPx), glutathione S-transferase and total antioxidant status, and non-enzymatic, through quantification of reduced glutathione, vitamin C and E, zinc and copper. CONCLUSION: It was observed that there was OS in the preeclamptic placentas, based on results, like lower activity of some of the enzymes of the antioxidant system (SOD and GPx) as well as the increase in oxidative damage markers (MDA and lipid peroxide), corroborating literature data.

Pre-eclampsia is associated with later kidney chronic disease and end-stage renal disease: Systematic review and meta-analysis of observational studies.

OBJECTIVES: To assess whether there is a risk of kidney disease during the postpartum period of women who had preeclampsia (PE). STUDY DESIGN: Observational trials were searched in the PubMed, Science Direct, Clinical trials, Cochrane, LILACS and Web of Science databases. The data extracted from the studies were systematized, and the risk of bias was evaluated for each of them. Meta-analyses were performed with studies that evaluated chronic kidney disease (CKD) and end-stage renal disease (ESRD), pooling the natural logarithms of the adjusted risk measures and the confidence intervals of each study in a random effects model. RESULTS: Of the 4149 studies evaluated, 35 articles were included in the review, of which 3 of the CKD and 6 of the ESRD presented the necessary outcomes to compose the meta-analysis. A formal registration protocol was included in the PROSPERO database (number: CRD42019111821). There was a statistically significant difference between the development of CKD (hazard ratio (HR): 1.82, confidence interval to 95% (95% CI): 1.27-2.62, P < 0.01) and ESRD (HR: 3.01, confidence interval to 95% (95% CI): 1.92-4.70, P < 0.01) in postpartum women affected by PE. CONCLUSIONS: PE was considered a risk factor for the onset of CKD and ESRD in the postpartum period. Thus, more research is needed to clarify the underlying mechanisms of this association, and to assist in determining the most appropriate and effective clinical conduct to prevent and/or treat such complications.

Evaluation of consumption of food and predictors of cardiovascular risk in hypertensive protectors of the State of Alagoas, Brazil. / Consumo de alimentos preditores e protetores de risco cardiovacular por hipertensos do estado de Alagoas, Brasil.

The present article aimed to evaluate the consumption of protective foods and predictors of cardiovascular (CV) risk and its relationship with cardiovascular risk factors (CVRF) by hypertensive individuals in the state of Alagoas. A population-based cross-sectional study was carried out from 2013 to 2016 with 655 hypertensive adults of both sexes. Food consumption was assessed by a validated food frequency questionnaire with measurements converted to scores and the foods were divided into three groups: I - processed foods/CV risk predictors; II - ultraprocessed foods/higher CV risk predictors; III - in natura or minimally processed foods/ CV risk protectors. Socioeconomic, demographic, biochemical, clinical and anthropometric variables were also analyzed. The consumption scores of food groups I, II and III were, respectively, 0.11; 0.13 and 0.24 (p = 0.001). The consumption of processed foods was correlated positively with high blood cholesterol (p = 0.045) and negatively with age (p = 0.001); while that of ultraprocessed foods was correlated with the sedentary lifestyle (p = 0.01). Thus, it was observed a relationship between the consumption of CV risk predictors foods with high blood cholesterol and sedentary lifestyle, reflecting the need for nutricional education actions.

Estudo transversal, de base populacional, com 655 adultos, hipertensos, de ambos os sexos, estudados no período de 2013 a 2016. O consumo alimentar foi avaliado por um questionário de frequência alimentar validado com mensuração convertida em escores e os alimentos foram divididos em três grupos: I - processados/preditores de risco CV; II - ultraprocessados/maiores preditores de risco CV; III - alimentos in natura ou minimamente processados/protetores de risco CV. Foram também analisadas variáveis socioeconômicas, demográficas, bioquímicas, clínicas e antropométricas. Os escores de consumo dos grupos de alimentos I, II e III foram, respectivamente, 0,11; 0,13 e 0,24 (p = 0,001). O consumo de alimentos processados se correlacionou positivamente com o colesterol sérico elevado (p = 0,045) e negativamente com a idade (p = 0,001); já o de alimentos ultraprocessados correlacionou-se com o sedentarismo (p = 0,01). Assim, observou-se relação entre o consumo de alimentos preditores de risco CV com sedentarismo e colesterol elevado, refletindo a necessidade de ações de educação nutricional.

Cross-Talk between Oxidative Stress and Inflammation in Preeclampsia.

The occurrence of hypertensive syndromes during pregnancy leads to high rates of maternal-fetal morbidity and mortality. Amongst them, preeclampsia (PE) is one of the most common. This review aims to describe the relationship between oxidative stress and inflammation in PE, aiming to reinforce its importance in the context of the disease and to discuss perspectives on clinical and nutritional treatment, in this line of research. Despite the still incomplete understanding of the pathophysiology of PE, it is well accepted that there are placental changes in pregnancy, associated with an imbalance between the production of reactive oxygen species and the antioxidant defence system, characterizing the placental oxidative stress that leads to an increase in the production of proinflammatory cytokines. Hence, a generalized inflammatory process occurs, besides the presence of progressive vascular endothelial damage, leading to the dysfunction of the placenta. There is no consensus in the literature on the best strategies for prevention and treatment of the disease, especially for the control of oxidative stress and inflammation. In view of the above, it is evident the important connection between oxidative stress and inflammatory process in the pathogenesis of PE, being that this disease is capable of causing serious implications on both maternal and fetal health. Reports on the use of anti-inflammatory and antioxidant compounds are analysed and still considered controversial. As such, the field is open for new basic and clinical research, aiming the development of innovative therapeutic approaches to prevent and to treat PE.

[Maternal nutritional status and its association with birth weight in high-risk pregnancies]. / Estado nutricional materno e sua associação com o peso ao nascer em gestações de alto risco.

The clinical and nutritional status of pregnant women are important variables for birth-weight risk inadequacies. Thus, this study sought to evaluate the nutritional status of high-risk pregnant women and its association with birth weight of their offspring. It involved a cross-sectional study with high-risk pregnant women assisted at the university hospital of Maceio in the State of Alagoas and their newborns. The nutritional status of pregnant women and their offspring was evaluated according to body mass index for gestational age and birth weight, respectively. The association between maternal factors (comorbidities and nutritional status) and birth weight was assessed by the chi-square test and Pearson correlation, by adopting a confidence level of 95%. One hundred and forty-nine pregnant women were studied, 19.7% of whom were of normal weight; 32% were underweight; and 48.3% were overweight. Among newborns, 39.6% referred to as small for gestational age (SGA); 26.8% appropriate for gestational age (AGA) and 33.6% large for gestational age (LGA). LGA offspring were associated with overweight and the presence of metabolic comorbidities and SGA offspring were associated with insufficient gestational weight gain, whereby interventions are needed to reduce these outcomes.

O estado clínico e o nutricional da gestante representam importantes variáveis para o risco de inadequações de peso ao nascer. Assim, o presente estudo visou avaliar o estado nutricional de gestantes de alto risco e sua associação com o peso ao nascer de seus conceptos. Estudo transversal com gestantes de alto risco assistidas no Hospital Universitário de Maceió-AL e seus recém-nascidos. O estado nutricional das gestantes e de seus conceptos foi avaliado segundo o Índice de Massa Corporal para a idade gestacional e o peso ao nascer, respectivamente. A associação entre fatores maternos (comorbidades e estado nutricional) e o peso ao nascer foram realizadas pelos testes de qui-quadrado e correlação de Pearson, adotando um nível de confiança de 95% (α = 0,05). Foram estudadas 149 gestantes, com 19,7% delas com baixo peso; 32,0% eutróficas e 48,3% com excesso de peso. Entre os recém-nascidos, 39,6% eram pequenos para idade gestacional (PIG); 26,8% adequados para a idade gestacional (AIG) e 33,6% grandes para a idade gestacional (GIG). O excesso de peso gestacional e a presença de comorbidades metabólicas se associaram com o nascimento de recém-nascidos GIG e o ganho ponderal gestacional insuficiente com o nascimento de recém-nascidos PIG, sendo fundamentais intervenções para redução desses desfechos.

Association between blood cholesterol and sodium intake in hypertensive women with excess weight.

Restricted sodium intake has been recommended for more than 1 century for the treatment of hypertension. However, restriction seems to increase blood cholesterol. In women with excess weight, blood cholesterol may increase even more because of insulin resistance and the high lipolytic activity of adipose tissue.The aim of this study was to assess the association between blood cholesterol and sodium intake in hypertensive women with and without excess weight.This was a cross-sectional study with hypertensive and nondiabetic women aged 20 to 59 years, recruited at the primary healthcare units of Maceio, Alagoas, Brazilian Northeast. Excess weight was defined as body mass index (BMI) ≥25.0 kg/m. Sodium intake was estimated by the 24-hour urinary excretion of sodium. Blood cholesterol was the primary outcome investigated by this study, and its relationship with sodium intake and other variables was assessed by Pearson correlation and multivariate linear regression using a significance level of 5%.This study included 165 hypertensive women. Of these, 135 (81.8%) were with excess weight. The mean sodium intake was 3.7 g (±1.9) and 3.4 g (±2.4) in hypertensive women with and without excess weight, respectively. The multiple normal linear regression models fitted to the "blood cholesterol" in the 2 groups reveal that for the group of hypertensive women without excess weight only 1 independent variable "age" is statistically significant to explain the variability of the blood cholesterol levels. However, for the group of hypertensive women with excess weight, 2 independent variables, age and sodium intake, can statistically explain variations of the blood cholesterol levels.Blood cholesterol is statistically inversely related to sodium intake for hypertensive women with excess weight, but it is not statistically related to sodium intake for hypertensive women without excess weight.

Cardiovascular risk assessment according to the Framingham score and abdominal obesity in individuals seen by a clinical school of nutrition.

OBJECTIVE: To analyze the relation of abdominal obesity on cardiovascular risk in individuals seen by a clinic school of nutrition, classifying them based on Framingham score. METHODS: Cross-sectional study, conducted at the nutrition clinic of a private college in the city of Maceió, Alagoas. We included randomly selected adults and elderly individuals with abdominal obesity, of both sexes, treated from August to December of 2009, with no history of cardiomyopathy or cardiovascular events. To determine the cardiovascular risk, the Framingham score was calculated. All analyzes were performed with SPSS software version 20.0, with p <0.05 as significative. RESULTS: We studied 54 subjects, 83% female, the mean age was 48 years old, ranging from 31 to 73 years. No correlation was observed between measurements of waist circumference and cardiovascular risk in the subjects studied (r=0.065, p=0.048), and there was no relationship between these parameters. CONCLUSION: Abdominal fat distribution was weakly related to cardiovascular risk in patients seen by a clinical school of nutrition.

Nutrition knowledge assessment studies in adults: a systematic review.

The objective of this study is to perform a systematic review of published studies that assessed nutrition knowledge in adults, focusing on the methodology and content of these studies. An article search was performed on the Medline, Lilacs, and SciELO databases. The search limits were human studies; English, Portuguese, and Spanish languages; and age (over 19). Inclusion criteria were: cross-sectional studies performed on individuals over 18 years old that assessed the general nutrition knowledge of participants. The methodological quality of the articles was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) criteria. The initial search identified 3,623 articles. After reading the titles and the abstracts and applying the exclusion criteria, 25 articles were selected. The results showed that, in most studies, nutrition knowledge was associated with socioeconomic parameters and eating behaviour. Most studies belonged to class B (92%), meeting 50-80% of the STROBE criteria. The studies have revealed a greater tendency to assess the relationship of nutrition knowledge with sociodemographic and economic parameters.

[Risk factors associated among anemia in pregnancy women of network public health of a capital of Brazil Northeastern]. / Fatores de associados à anemia em gestantes da rede pública de saúde de uma capital do Nordeste do Brasil.

PURPOSE: To evaluate the factors associated with anemia among pregnant women receiving public health care in a capital city in Northeastern Brazil. METHODS: This was a cross-sectional study conducted on a sample of 428 patients obtained on the basis of the estimated prevalence of anemia during pregnancy (50%), a 95% confidence interval (95%CI), an error of 5% and a sample loss of 20%. Pregnant women who lived in the city and were served by the municipal public health network were considered to be eligible for the study. Socioeconomic, lifestyle, clinical and anthropometric data and dietary iron intake were obtained, and capillary hemoglobin was determined. Anemia was identified as a hemoglobin level <11 g/dL, and its association with risk factors was tested using multivariate Poisson regression analysis, with the results expressed as the Prevalence Ratio (PR) and 95%CI. RESULTS: The prevalence of anemia was 28.3% and was higher among women with more members in the household (PR=1.49; 95%CI 1.01-2.22; p=0.046) and those living with food insecurity (PR=1.43; 95%CI 1.00-2.04; p=0.047). CONCLUSION: The prevalence of anemia among pregnant women receiving care from the public health system of the city is a moderate public health problem, requiring the planning of effective measures for its control.

Associated factors with excessive weight gain in pregnant women from Maceió, Northeastern Brazil / Fatores associados ao ganho ponderal excessivo em gestantes de Maceió, Nordeste do Brasil

Abstract This article aims to evaluate the associated factors with excessive weight gain in pregnant women from Maceió, the capital of Alagoas, Northeastern Brazil. Cross-sectional study with pregnant women attended in public health in the city of Maceió in 2014, of which socioeconomic, clinical (glycemia, capillary hemoglobin, and blood pressure measurement), dietary, and anthropometric data, including in the latter gestational weight gain, classified as insufficient, adequate and excessive according to the US Institute of Medicine, were collected. The combination of excessive weight gain with the independent variables was tested using the Poisson regression expressed by the Prevalence Ratio (PR) and a 95% confidence interval (CI95%). We studied 403 pregnant women with a mean age of 24.08 ± 6.01 years, with 19.9% of them displayed insufficient weight gain; 14.1% displayed adequate weight gain, and 66.0% displayed excessive weight gain, that was associated with maternal hyperglycemia (PR = 1.35; CI95% = 1.17 to 1.57; p < 0.001). Excessive weight gain is common among pregnant women evaluated with the association of this variable with maternal hyperglycemia.

Abstract The present article aimed to evaluate the consumption of protective foods and predictors of cardiovascular (CV) risk and its relationship with cardiovascular risk factors (CVRF) by hypertensive individuals in the state of Alagoas. A population-based cross-sectional study was carried out from 2013 to 2016 with 655 hypertensive adults of both sexes. Food consumption was assessed by a validated food frequency questionnaire with measurements converted to scores and the foods were divided into three groups: I - processed foods/CV risk predictors; II - ultraprocessed foods/higher CV risk predictors; III - in natura or minimally processed foods/ CV risk protectors. Socioeconomic, demographic, biochemical, clinical and anthropometric variables were also analyzed. The consumption scores of food groups I, II and III were, respectively, 0.11; 0.13 and 0.24 (p = 0.001). The consumption of processed foods was correlated positively with high blood cholesterol (p = 0.045) and negatively with age (p = 0.001); while that of ultraprocessed foods was correlated with the sedentary lifestyle (p = 0.01). Thus, it was observed a relationship between the consumption of CV risk predictors foods with high blood cholesterol and sedentary lifestyle, reflecting the need for nutricional education actions.

Adverse perinatal outcomes of pregnancies among adolescents vs women of advanced age in the Brazilian public health system / Resultados perinatais adversos das gestações de adolescentes vs de mulheres em idade avançada na rede brasileira de saúde pública

Abstract Objectives: to compare the adverse perinatal outcomes in pregnancies of adolescents and elderly women of public health network. Methods: a cross-sectional study carried out with pregnant women at the extremes of reproductive age according to the classification of the Brazilian Ministry of Health (adolescents those aged ≤19 years and those who were older than 35 years) and their newborns. Socioeconomic data (income, schooling, occupation and marital status), as well as clinical (diseases), anthropometric (maternal BMI) and perinatal (gender, weight, length, Apgar and gestational age) data were collected, and Poisson regression in hierarchical model was performed, with the results in Ratio of Prevalence (PR) and its respective Confidence Interval at 95% (95% CI). Results: when comparing adolescent and elderly women, 38.7% vs 54.6% (PR=0.71, CI=0.54-0.94, p=0.002) were observed, respectively, cesarean deliveries; 37.8% vs 25.2% (PR=0.83, CI=0.58-1.19, p=0.332) preterm births; 16.6% vs 20.5% (RP=1.07, CI=0.78-1.46, p=0.666) births of small infants for gestational age (SGA); 18.0% vs 15.3% (RP=1.01, CI=0.69-1.47, p=0.948) births of large-for-gestational-age newborns (LGA); 32.2% vs 34.7% (RP=1.08, CI=0.82-1.42, p=0.578), low birth weight infants and 28.5% vs 42.9% (RP=1.18, CI=0.91-1.54, p=0.201) with high birth length. Conclusions: When compared with adolescent women, pregnant women of advanced age presented a higher frequency of cesarean deliveries.

Resumo Objetivos: comparar os resultados perinatais adversos em gestações de adolescentes e mulheres em idade avançada de rede pública de saúde. Métodos: estudo transversal realizado com gestantes nos extremos de idade reprodutiva segundo classificação do Ministério da Saúde do Brasil (adolescentes aquelas com idade ≤19 anos e em idade avançada aquelas com idade ≥35 anos) e seus recém-nascidos. Foram coletados dados socioeconômicos (renda, escolaridade, ocupação e situação conjugal), clínicos (presença de doenças), antropométricos (IMC materno) e perinatais (sexo, peso, comprimento, Apgar e idade gestacional), e realizada regressão de Poisson em modelo hie-rarquizado, com resultados em Razão de Prevalência (RP) e respectivo Intervalo de Confiança a 95% (IC95%). Resultados: quando comparadas gestantes adolescentes e aquelas em idade avançada, foram observados, respectivamente: 38,7% vs 54,6% (RP=0,71; IC=0,54-0,94; p=0,002) partos cesarianos; 37,8% vs 25,2% (RP=0,83; IC=0,58-1,19; p=0,332) nascimentos de pré-termos; 16,6% vs 20,5% (RP=1,07; IC=0,78-1,46; p=0,666) nascimentos de recém-nascidos pequenos para idade gestacional; 18,0% vs 15,3% (RP=1,01; IC=0,69-1,47; p=0,948) nascimentos de recém-nascidos grandes para a idade gestacional; 32,2% vs 34,7% (RP=1,08; IC=0,82-1,42; p=0,578)recém-nascidos com baixo peso ao nascer e28,5% vs 42,9% (RP=1,18; IC=0,91-1,54; p=0,201) com comprimento elevado ao nascer. Conclusões: as gestantes em idade avançada quando comparadas com as adolescentes apresentaram maior frequência de partos cesarianos.

Estado nutricional materno e sua associação com o peso ao nascer em gestações de alto risco / Maternal nutritional status and its association with birth weight in high-risk pregnancies

Resumo O estado clínico e o nutricional da gestante representam importantes variáveis para o risco de inadequações de peso ao nascer. Assim, o presente estudo visou avaliar o estado nutricional de gestantes de alto risco e sua associação com o peso ao nascer de seus conceptos. Estudo transversal com gestantes de alto risco assistidas no Hospital Universitário de Maceió-AL e seus recém-nascidos. O estado nutricional das gestantes e de seus conceptos foi avaliado segundo o Índice de Massa Corporal para a idade gestacional e o peso ao nascer, respectivamente. A associação entre fatores maternos (comorbidades e estado nutricional) e o peso ao nascer foram realizadas pelos testes de qui-quadrado e correlação de Pearson, adotando um nível de confiança de 95% (α = 0,05). Foram estudadas 149 gestantes, com 19,7% delas com baixo peso; 32,0% eutróficas e 48,3% com excesso de peso. Entre os recém-nascidos, 39,6% eram pequenos para idade gestacional (PIG); 26,8% adequados para a idade gestacional (AIG) e 33,6% grandes para a idade gestacional (GIG). O excesso de peso gestacional e a presença de comorbidades metabólicas se associaram com o nascimento de recém-nascidos GIG e o ganho ponderal gestacional insuficiente com o nascimento de recém-nascidos PIG, sendo fundamentais intervenções para redução desses desfechos.

Abstract The clinical and nutritional status of pregnant women are important variables for birth-weight risk inadequacies. Thus, this study sought to evaluate the nutritional status of high-risk pregnant women and its association with birth weight of their offspring. It involved a cross-sectional study with high-risk pregnant women assisted at the university hospital of Maceio in the State of Alagoas and their newborns. The nutritional status of pregnant women and their offspring was evaluated according to body mass index for gestational age and birth weight, respectively. The association between maternal factors (comorbidities and nutritional status) and birth weight was assessed by the chi-square test and Pearson correlation, by adopting a confidence level of 95%. One hundred and forty-nine pregnant women were studied, 19.7% of whom were of normal weight; 32% were underweight; and 48.3% were overweight. Among newborns, 39.6% referred to as small for gestational age (SGA); 26.8% appropriate for gestational age (AGA) and 33.6% large for gestational age (LGA). LGA offspring were associated with overweight and the presence of metabolic comorbidities and SGA offspring were associated with insufficient gestational weight gain, whereby interventions are needed to reduce these outcomes.

Fatores associados à não utilização de suplemento antianêmico por gestantes de alto risco de Alagoas, Brasil / Associated factors to non-use of antianemic supplementation by high risk pregnant women in Alagoas, Brazil

Introdução: Apesar das estratégias e da implementação de guias e políticas para o combate à anemia carencial terem sido adotadas há bastante tempo, a sua prevalência no país vem se mantendo elevada, especialmente em grupos especiais, sendo esta carência considerada um problema de saúde pública. Assim, o objetivo desse estudo foi avaliar a prevalência e os fatores associados à não utilização de suplemento antianêmico por gestantes de alto risco de Alagoas. Método: Estudo transversal, realizado com gestantes assistidas no hospital universitário de Maceió, sendo estudadas variáveis socioeconômicas, de estilo de vida, antropométricas, e investigado o uso de suplementação ferrosa, com utilização da regressão de Poisson, e resultados expressos em razão de prevalência (RP) e intervalos de confiança (IC) de 95%. Resultados: Foram estudadas 210 gestantes na faixa etária de 13 a 43 anos de idade. O não uso de suplemento ferroso foi referido por 37,6% das mesmas, estando associado (gestantes que não utilizavam suplementação profilática versus gestantes que utilizavam suplementação profilática) ao baixo peso na gravidez, sendo, essa variável fator de proteção para esta condição (RP=0,47; IC de 95%= 0,24 a 0,93; p=0,030). Conclusão: A não utilização da suplementação antianêmica por parte de gestantes de alto risco de Alagoas é um problema de magnitude elevada, tornando evidente a necessidade de aumentar a cobertura da suplementação antianêmica entre elas.
