The objective of this study was to evaluate the socioeconomic and nutritional assistance factors of pregnant women who are beneficiaries of the Bolsa Família Program and were attended at a prenatal service in the city of Recôncavo da Bahia. A cohort study was conducted with 250 pregnant women from the prenatal service in 16 Family Health Units from August 2013 to December 2014. A structured and previously tested questionnaire was used to collect data. Socioeconomic and nutritional variables were used. It was identified that the average age was 28.3 years, of these, 85.2% studied until high school, 72.4% of pregnant women reported having income less than or equal to two minimum wages, with a mean of 1,036.3 and 26.8% reported receiving the benefit. It was observed that 40% had a pre-gestational Body Mass Index of overweight, 38% presented adequate weight gain for Gestational Age; 90.57% performed more than 7 consultations and 75.6% reported that they made use of alcoholic beverages or stopped in the gestation. The Bolsa Família Program as an integrated strategy for social inclusion and economic development seems to have a protective effect on the nutritional health of pregnant women in the municipality.

Objectives To contribute to a better understanding of the maternal genetic mechanisms that influence obstetric outcomes and that are involved in maternal and child health, this study aimed to evaluate the association between maternal genetic variants and the offspring birth weight by analyzing single-nucleotide polymorphisms (SNPs) in genes related to glucose homeostasis. Methods Three polymorphisms were analyzed (GCK rs1799884, TCF7L2 rs7903146 and LEPR rs1137101) in 250 pregnant women who participated in a Brazilian prospective cohort study. Genotyping was performed by Real-Time Polymerase Chain Reaction (qPCR) using pre-designed TaqMan® SNP genotyping assays. Vitamin D dosage was performed by chemiluminescence. Variance, Pearson's chi-square test and multiple linear regression were used for the statistical analysis. Results It was possible to verify a significant association between birth weight and maternal GCK rs1799884 when obstetric outcomes, clinical and anthropometric characteristics were taken into consideration. The children of homozygous women for the minor allele GCK rs1799884 presented lower birth weight (β = -335.25, 95% CI = -669.39; -1.17, p = 0.04). Furthermore, a direct link between a leptin receptor variant and gestational duration was found (p = 0.037). Conclusion The variant GCK rs1799884 (mm) was associated with a reduction in newborn weight in the miscegenated Brazilian population.

The polymorphisms of fatty acid desaturase genes FADS1 and FADS2 have been associated with an increase in weight gain. We investigated FADS1 and FADS2 gene polymorphisms and the relation between ω-3 and ω-6 fatty acid plasma concentrations and gestational weight gain. A prospective cohort study of 199 pregnant women was followed in Santo Antônio de Jesus, Brazil. Plasma levels of polyunsaturated fatty acids (PUFAs) were measured at baseline and gestational weight gain during the first, second, and third trimesters. Fatty acid recognition was carried out with the aid of gas chromatography. Single nucleotide polymorphisms (SNPs) were genotyped using real-time PCR. Statistical analyses included Structural Equation Modelling. A direct effect of FADS1 and FADS2 gene polymorphisms on gestational weight was observed; however, only the SNP rs174575 (FADS2) showed a significant positive direct effect on weight over the course of the pregnancy (0.106; p = 0.016). In terms of the influence of SNPs on plasma levels of PUFAs, it was found that SNP rs174561 (FADS1) and SNP rs174575 (FADS2) showed direct adverse effects on plasma concentrations of ω-3 (eicosapentaenoic acid and alpha-linoleic acid), and only SNP rs174575 had positive direct effects on plasma levels of ARA and the ARA/LA (arachidonic acid/linoleic acid) ratio, ω-6 products, while the SNP rs3834458 (FADS2) had an adverse effect on plasma concentrations of EPA, leading to its increase. Pregnant women who were heterozygous and homozygous for the minor allele of the SNP rs3834458 (FADS2), on the other hand, showed larger concentrations of series ω-3 substrates, which indicates a protective factor for women’s health.

A high number of women are exposed to acetaminophen during pregnancy worldwide. This drug safety during pregnancy regarding preterm birth, birth weight, and fetal development has not been well described. This study investigated the effect of acetaminophen use during pregnancy on selected adverse pregnancy outcomes. Databases were searched to identify studies reporting the effects of acetaminophen use during pregnancy on preterm birth, low birth weight, and small for gestational age. The studies’ quality was assessed by the Newcastle-Ottawa Scale and the Methodological Index for Non-Randomized Studies. Risk ratios with 95% confidence intervals were estimated using a fixed or random‐effects model. Six studies were included for final review, four cohort and two case‐control studies. We found no increased risk of preterm birth (RR 0.97; 95% CI 0.59–1.58), and decreased risks of low birth weight (RR 0.65; 95% CI 0.59–0.72) and small for gestational age (RR 0.69; 95% CI 0.50–0.97). Acetaminophen exposure during the third trimester revealed non-significantly in the outcomes. Exposure to acetaminophen during pregnancy appears to not increase the risk of the outcomes analyzed. However, there is a lack of information regarding the exposure dose and frequency of acetaminophen use.

Context Epidemiological studies suggest an association between vitamin D deficiency and anemia. Evidence of this relationship in pregnant women, however, is scarce. Objective The aim of this systematic review was to investigate the association between vitamin D deficiency and gestational anemia through observational studies. Data Sources The PubMed, Scopus, Web of Science, ScienceDirect, Embase, and Virtual Health Library databases were searched from inception to April 2021. Study Selection Original articles reporting observational studies that investigated the association between vitamin D deficiency and gestational anemia were included. Articles that did not have an abstract, as well as reviews articles, experimental studies, and editorials, were excluded. Two reviewers independently performed study selection, data extraction, and assessment of study quality. Disagreements between the reviewers were resolved by a third reviewer. Data Extraction Study quality was assessed by 2 scales. Data were extracted from eligible studies and arranged in a 2 × 2 table. Odds ratios with 95% confidence intervals for the risk of the outcome were estimated using a fixed-effect model. Results In total, 985 studies were retrieved, of which 17 were included in the systematic review: 11 cohort studies, 3 case-control studies, and 3 cross-sectional studies. For the meta-analysis, 8 studies with a total of 6530 women were included. There was a 61% increase in the odds of anemia in pregnant women with vitamin D deficiency (OR = 1.61; 95%CI, 1.41–1.83; I2 = 48%). Conclusions Vitamin D deficiency may be a risk factor for anemia in pregnant women. Systematic Review Registration PROSPERO registration no. CRD42020182697.

OBJECTIVES Few studies have investigated the influence of polyunsaturated fatty acid consumption on excessive weight gain during pregnancy. Thus, we analyzed the association between the intake of polyunsaturated fatty acids (ω-6 and ω-3) and weight gain in women during pregnancy. METHODS This is a cohort study of 250 pregnant women enrolled in municipal pre-natal services. Weight, height, and dietary intake of polyunsaturated fatty acids were evaluated at the baseline. The semi-quantitative food frequency questionnaire was employed to assess the main exposure. Gestational weight was measured in the first, second, and third trimesters. A dietary pattern involving the consumption of fatty acids was identified through factor analysis. A generalized estimating equation was used for the data analysis. RESULTS The prevalence of excessive weight gain at the end of pregnancy was 35.2%. Consumption patterns 1 (salted meats, offal, vegetable oil, snacks, legumes, and oleaginous foods) and 2 (red meat, sausages, butter, margarine, mayonnaise, acaraje, caruru, vatapa, and refined cereals) revealed a risk for the accumulation of excess weight during pregnancy. Women who adhered to consumption patterns 1 (RR: 2.39; 95% CI: 1.44-3.94) and 2 (RR: 2.39; 95% CI: 1.44-3.94) were more susceptible to excess weight gain during pregnancy. CONCLUSIONS Women who adhered to dietary patterns involving foods that are sources of ω-6 fatty acids and saturated fatty acids were more susceptible to gaining weight during pregnancy compared to those who adhered less to these patterns.

The relationship among social determinants, vitamin D serum concentration and the health and nutrition conditions is an important issue in the healthcare of pregnant women and newborns. Thus, the present study analyses how vitamin D, prenatal monitoring and social determinants are associated with birth weight. The cohort comprised 329 pregnant women, up to 34 weeks gestational age at the time of admission, who were receiving care through the prenatal services of Family Health Units. Structural equation modelling was used in the statistical analysis. The mean birth weight was 3340 (sd 0·545) g. Each nmol increase in maternal vitamin D serum concentration was associated with an increase in birth weight of 3·06 g. Prenatal healthcare with fewer appointments (β −41·49 g, 95 % CI −79·27, −3·71) and late onset of care in the second trimester or third trimester (β −39·24 g, 95 % CI −73·31, −5·16) favoured decreased birth weight. In addition, low socio-economic class and the practice of Afro-Brazilian religions showed a direct association with high vitamin D serum concentrations and an indirect association with high birth weight, respectively. High gestational BMI (β 23·84, 95 % CI 4·37, 43·31), maternal education level (β 24·52 g, 95 % CI 1·82, 47·23) and length of gestation (β 79·71, 95 % CI 52·81; 106·6) resulted in high birth weight. In conclusion, maternal vitamin D serum concentration, social determinants and prenatal care, evaluated in the context of primary healthcare, directly determined birth weight.

This study aimed to investigate the factors associated with drug use in pregnancy by risk categories in pregnant women from Santo Antônio de Jesus, Bahia. It is a cross-sectional cohort study with 1,091 pregnant women attended in primary health care between 2012 and 2014. Drug use during pregnancy was classified according to the FDA’s pregnancy risk classification. Prevalence ratios and respective 95% confidence intervals were adjusted by Poisson regression with robust error variance. The prevalence of drug use was more pronounced in risk categories A, B, C, D, and X, respectively. The use of safe medication was associated with education, number of prenatal consultations, and health problems after data adjustment. Age greater than 24 years, onset of prenatal care during the first trimester, and have any health problem were factors associated with the use of risk medication. Quality prenatal care is important to ensure the safe and conscious use of drugs. Furthermore, investments in continuing vocational education that promote rational antenatal drug use are needed. Este estudio tuvo como objetivo investigar los factores asociados al uso de medicamentos en el embarazo por categorías de riesgo en gestantes del municipio de Santo Antônio de Jesus, Bahía. Se trata de un estudio transversal anidado en la cohorte prospectiva con 1.091 gestantes atendidas en atención primaria de salud entre 2012 y 2014. El uso de medicamentos durante el embarazo siguió la clasificación de medicamentos según los criterios de riesgo de la FDA. Las razones de prevalencia y sus respectivos intervalos de confianza del 95% se ajustaron mediante regresión de Poisson con varianza robusta. La prevalencia del uso de medicamentos fue más pronunciada en las categorías de riesgo A, B, C, D y X, respectivamente. Después del ajuste, el uso de medicamentos seguros se asoció con educación, número de consultas prenatales y problemas de salud. Tener más de 24 años, iniciar la atención prenatal en el primer trimestre y tener un problema de salud fueron factores asociados al uso de medicamentos de riesgo. La atención prenatal de calidad es importante para garantizar el uso seguro y consciente de los medicamentos. Además, se necesitan inversiones en educación profesional continua para promover el uso racional de los medicamentos en el período prenatal.

Objectives: this study aims to evaluate the association between gestational weight gain and the weight of newborns from one municipality in Recôncavo Baiano region. Methods: this is a prospective cohort (NISAMI Cohort), conducted with 185 pregnant women living in the urban area of the municipality of Santo Antônio de Jesus, using the prenatal service of the Family Health Units, between April 2012 and June 2013. The pregestationalBMI and the third trimester of pregnancy were used to assess maternal anthropometric status.Birth weight data were collected from the Epidemiological Surveillance of the municipality. Stata 12.0 software was used for statistical analysis. Logistic regression analysis was used to evaluate to assess the association. Results: among the 185 women evaluated, 33.5% presented inadequate weight gain during pregnancy. The prevalence of inadequate birth weight was 20% (birth weight ≤ 2.999g and ≥ 4.000 g). It was observed that inadequate weight gain during pregnancy is considered an embarrassing factor for birth weight (OR= 2.6; CI95%= 1.5-3.5); adjusted for the following variables: alcohol consumption, duration of pregnancy, and gestational complications. Conclusion: the research results suggest that weight gain throughout pregnancy influences the weight of the conceptus, indicating the need for nutritional interventions in all trimesters of pregnancy, promoting a healthy weight gain throughout the gestational cycle. Resumo Objetivos: avaliar a associação entre ganho ponderal na gestação e o peso de recém-nascidos em um município do Recôncavo Baiano. Métodos: trata-se de uma coorte prospectiva (Coorte NISAMI), conduzida com 185 gestantes residentes na zona urbana do município de Santo Antônio de Jesus, captadas no serviço de pré-natal das Unidades de Saúde da Família, entre abril de 2012 a junho de 2013. O IMC pré-gestacional e do terceiro trimestre da gestação foram utilizados para avaliar o estado antropométrico materno. Os dados de peso ao nascer foram coletados da Vigilância Epidemiológica do município. Utilizou-se o software Stata 12.0 para as análises estatísticas. Empregou-se análise de regressão logística para avaliar a associação. Resultados: das 185 mulheres, 33,5% apresentaram ganho ponderal inadequado ao longo da gestação. A prevalência de peso inadequado ao nascer foi de 20% (peso ao nascer ≤2.999g e ≥ 4.000 g). Observou-se que o ganho de peso inadequado no período gestacional é considerado fator constrangedor do peso ao nascer (OR= 2,6; IC95%= 1,5-3,5; ajustado pelas variáveis: consumo de bebida alcoólica, duração da gestação e intercorrências gestacionais. Conclusão: o resultado desta investigação sugere que o ganho de peso ao longo da gestação exerce influência no peso do concepto indicando necessidade de intervenções nutricionais em todos os trimestres da gestação, promovendo um ganho ponderal saudável em todo ciclo gestacional.

The association between FI, social determinants, and nutritional outcomes for pregnant women are analyzed. A systematic review was conducted through a search of articles in five electronic databases. Social determinants (race, education, participation in social programs) and nutritional status (pre-gestational BMI, gestational weight gain, anemia) were analyzed in relation to the FI situation. For each article, the frequency of food insecurity was collected in order to calculate the summary measure, prevalence ratio (PR). 26 articles were selected. An elevated occurrence of FI was associated with black pregnant women (PR: 1.83, 95% CI 1.08-3.10), participation in social protection programs (PR = 1.43, 1.02-2.01), and with low education levels on the part of pregnant women (PR = 2.73, 1.68-4.43). FI increased the chances of being overweight (PR = 1.57, 95% CI = 1.29-1.91) and obese (PR = 1.47, 95% CI = 1.15-1.87) in pregnant women, as well as excessive weight gain (PR = 1.42, 95% CI = 1.10-1.82) and inadequate weight gain (PR = 1.47; 95% CI = 1.09-1.97) during pregnancy. Anemia was not associated with FI. Social inequities are associated with food and nutritional insecurity in pregnant women. Resumo O estudo objetiva analisar a associação entre insegurança alimentar, determinantes sociais e estado nutricional de mulheres gestantes por meio de uma revisão sistemática e metanálise. As buscas de artigos ocorreram em cinco bases eletrônicas. Determinantes sociais (raça, escolaridade, participação em programa social) e estado nutricional (IMC pré-gestacional, ganho de peso gestacional, anemia) foram analisados em relação à situação de IA. Em cada estudo, a frequência de insegurança alimentar foi coletada para calcular a medida sumário- razão de prevalência (RP) e seu intervalo de confiança de 95%(IC95%). Foram selecionados 26 artigos. Observou-se elevada ocorrência de IA em gestantes pretas (RP:1,83; IC 95% 1,08-3.10), naquelas com participação em programas de proteção social (RP = 1.43; IC 95%= 1.02- 2.01) e com baixo nível de escolaridade (RP = 2.73; IC 95%= 1.68-4.43). O fato de a gestante possuir companheiro protegeu contra IA (RP = 0.61; IC 95%= 0.40-0.95). A experimentação da IA elevou a chance de sobrepeso (RP = 1.57; IC 95% = 1.29-1.91) e de obesidade (RP = 1.47; IC 95% = 1.15-1.87), assim como o ganho excessivo (RP = 1.42; IC 95% = 1.10-1.82) e inadequado (RP = 1.47; IC 95%= 1.09-1.97) de peso na gestação. Iniquidades sociais estão associadas a IA em gestantes.

This study aimed to assess the impact of the Bolsa Familia Program on perinatal outcomes of pregnant women. A cohort study was conducted with pregnant women supported by prenatal services at 17 Family Health Units in Bahia, Brazil. A previously tested structured questionnaire, which has sociodemographic, economic, prenatal care, lifestyle, and nutritional variables, has been used to collect data. The outcomes included premature birth and low birth weight. A hierarchical conceptual model was constructed, and logistic regression analysis was performed. From a total of 1173 pregnant women, the identified average age was 25.44 years and 34.10% had pre-gestational overweight. The non-beneficiary pregnant women presented a 1.54 (95% CI = 0.46–5.09) times higher chance of giving birth to children with low weight and a 1.03 (95% CI = 95% CI = 0.53–2.00) times chance of premature birth when compared to the beneficiary group. In the multilevel model, some variables were statistically significant, such as age between 18 and 24 years (p = 0.003), age greater than or equal to 35 years (p = 0.025), family income (p = 0.008), employment status (p = 0.010), and maternal height (p = 0.009). The Bolsa Familia Program, as an integrated strategy of social inclusion and economic development, is suggested to exert a protective effect on the health of mother-concept binomial.

Summary Objective We analyzed the serum vitamin D concentrations and identified the factors associated with vitamin D deficiency in Brazilian pregnant women, in a city with a high solar exposure. Methods Cross-sectional study with a sample of 190 pregnant women in a municipality in the Brazilian state of Bahia. Socio-environmental information, regarding the lifestyle and biological factors of participants, was collected and recorded in a questionnaire, and serum concentrations of 25(OH)D was determined (PR). Results The deficient and insufficient vitamin D concentrations were found in 14.21% and 44.74% of the pregnant women, respectively. Vitamin D deficiency was associated with commuting to work via motor vehicles (PR: 2.79; 95% CI: 1.06–7.31), with winter (prevalence ratio – PR: 1.54; 95% CI: 1.01–2.35), exposure to the sun only on the face and hands (PR: 2.99; 95% CI: 1.35–6.63) and single pregnant women (PR: 2.53; 95% CI: 1.01–6.35). Conclusions We detected a high proportion of pregnant women with vitamin deficient and insufficient vitamin D levels among pregnant women of a sunny city. These data suggest the necessity to monitor serum vitamin D levels during pregnancy and the adequate orientation in prenatal care to adoption healthy lifestyle for the prevention of vitamin D deficiency in this population.

The mother’s diet during pregnancy is associated with maternal and child health. However, there are few studies with moderation analysis on maternal dietary patterns and infant birth weight. We aim to analyse the association between dietary patterns during pregnancy and birth weight. A prospective cohort study was performed with pregnant women registered with the prenatal service (Bahia, Brazil). A food frequency questionnaire was used to evaluate dietary intake. Birth weight was measured by a prenatal service team. Statistical analyses were performed using factor analysis with a principal component extraction technique and structural equation modelling. The mean age of the pregnant women was 27 years old (SD: 5.5) and the mean birth weight was 3341.18 g. It was observed that alcohol consumption (p = 0.05) and weight-gain during pregnancy (p = 0.05) were associated with birth weight. Four patterns of dietary consumption were identified for each trimester of the pregnancy evaluated. Adherence to the “Meat, Eggs, Fried Snacks and Processed foods” dietary pattern (pattern 1) and the “Sugars and Sweets” dietary pattern (pattern 4) in the third trimester directly reduced birth weight, by 98.42 g (Confidence interval (CI) 95%: 24.26, 172.59) and 92.03 g (CI 95%: 39.88, 165.30), respectively. It was also observed that insufficient dietary consumption in the third trimester increases maternal complications during pregnancy, indirectly reducing birth weight by 145 g (CI 95%: −21.39, −211.45). Inadequate dietary intake in the third trimester appears to have negative results on birth weight, directly and indirectly, but more studies are needed to clarify these causal paths, especially investigations of the influence of the maternal dietary pattern on the infant gut microbiota and the impacts on perinatal outcomes.

There is a lack of studies about polymorphisms in FADS genes in pregnant women. We aimed to verify the interaction between three FADS gene polymorphisms (rs174561; rs174575; rs3834458) and dietary α-linolenic acid (ALA) or linoleic/α-linolenic acid ratio (LA/ALA) and plasma concentrations of omega-3 (n-3) PUFAs in pregnant women. Of the 250 women evaluated, the homozygous for the rs174561 and rs3834458 minor allele had high plasma ALA concentrations at the highest ALA and LA/ALA ratio tertile (p 0.05). Plasma concentrations of EPA and DHA were not influenced by diet. For the rs174575 SNP, pregnant women who carried the minor allele presented lower proportions of plasma EPA in the second LA/ALA ratio tertile (p 0.05). Increased dietary intake of ALA and LA/ALA ratio promoted plasma ALA accumulation in homozygotes for the minor allele rs174561 and rs3834458. Moderate intake of LA/ALA ratio may reduce plasma concentration of EPA in pregnants carrying the rs174575 minor allele.

Food plays essential role for the health of pregnant women. Due to the intense metabolism period, it is necessary healthy food consumption which ensures the development of an adequate pregnancy. Due to this information, the aim of this study is to analyze the adequacy of food groups consumed by pregnant women attending prenatal consultations in the health units of the municipality Reconcavo in Bahia. It is a cross sectional study involving pregnant women in prenatal service of the public network over the years 2010, 2011 and 2012. It was used structured questionnaire with socio-demographic information, obstetric and health. To assess food consumption it was used the Survey of Food Consumption Frequency (FFQ). The portions of the food groups were determined then analyzed according to the food pyramid adapted to the Brazilian population. It was also analyzed the socioeconomic characteristics of the sample. They interviewed 70 pregnant women aged between 20 and 45 years. Among these women, 75.8% were married or in a stable relationship, 78.6% with high school degree, 36.2% had family income lower than the minimum wage and 41.5% declare themselves as black. It was observed that the socioeconomic characteristics can influence directly on the diet of pregnant women. In the analysis of food groups was noted insufficient intake of legumes, milk and dairy products, and excessive consumption of the group of sugar/sweets and meats and eggs. There was inadequate food consumption in terms of qualitative (food groups), not taking into account the specific needs of the gestational cycle, which may result in nutritional risk to mother and fetus.

OBJETIVO: Analisar a associação entre raça/cor da pele e a ocorrência da prematuridade. MÉTODOS: Meta-análise com estudos observacionais, selecionados por revisão sistemática em bases de dados bibliográficos Medline e Biblioteca Virtual da Saúde com os descritores: “Race or ethnic group” e “ethnicity and health” associados às palavras “infant premature” e “obstetric labor premature”. Foram incluídos os artigos publicados no período de 2010 a 2014, do tipo epidemiológico observacional, nas línguas portuguesa, inglesa e espanhola. Foram excluídos os artigos que não possuíam resumos ou que fossem artigos de revisão, teses, dissertações e editorias. Foi adotado o risco relativo e seus respectivos intervalos de confiança (IC95%) como medidas de efeito, obtidos por meio do modelo de efeito aleatório e representados a partir do gráfico do tipo forest plot. Para analisar os possíveis vieses de publicação e qualidade dos estudos, foi utilizado o teste de Egger e a escala de Newcastle-Ottawa, respectivamente. RESULTADOS: Dos 926 artigos identificados, 17 foram elegíveis para o estudo. Dos 17 textos completos publicados, sete eram estudos de coorte retrospectiva, nove eram transversais e um era caso-controle. Com exceção de um estudo, os demais relataram associação positiva entre a raça/cor da pele e a prematuridade. Comparado com recém-nascidos a termo, o risco relativo do efeito combinado naqueles que nasceram prematuros foi de 1,51 (IC95% 1,39–1,69). O gráfico de funil sugeriu viés de publicação. CONCLUSÕES: A presente meta-análise indicou uma associação positiva para o risco da prematuridade segundo a raça/cor da pele.

OBJECTIVE To analyze the association between race/skin color and the occurrence of prematurity. METHODS Meta-analysis with observational studies, selected by a systematic review in the bibliographic databases Medline and Biblioteca Virtual da Saúde with the descriptors: “Race or ethnic group” and “ethnicity and health” associated with the words “infant premature” and “obstetric labor premature”. Articles published in the period from 2010 to 2014, of the observational epidemiological type, in Portuguese, English and Spanish, were included. Articles that did not have abstracts or that were review articles, theses, dissertations, and editorials were excluded. We adopted the relative risk and their respective confidence intervals (95%CI) as measures of effect, obtained through the random effect model and represented by the forest plot type graph. The Egger test and the Newcastle-Ottawa scale, respectively, were used to analyze possible publication biases and the quality of the studies. RESULTS Of the 926 articles identified, 17 were eligible for the study. Of the 17 full texts published, seven were retrospective cohort studies, nine were cross-sectional studies, and one was a case-control study. Except for one study, the others reported a positive association between race/color of skin and prematurity. Compared with full-term newborns, the relative risk of the combined effect in those born preterm was 1.51 (95%CI 1.39-1.69). The funnel chart suggested publication bias. CONCLUSIONS The present meta-analysis indicated a positive association for the risk of prematurity according to race/skin color.

Objective To identify the prevalence of anemia and its relation to food insecurity (FI) and other determinants in pregnant women. Methods A cross-sectional, cohort-nested study, with the participation of 245 pregnant women who were cared for at Family Health Units in the municipality of Santo Antônio de Jesus, Bahia, Brazil. The participants underwent blood tests for hemoglobin levels, anthropometric examinations, and answered a structured questionnaire. The hemoglobin (Hb) parameter (Hb < 11 g/dL) was used for the classification of the diagnosis of anemia. Food insecurity was evaluated using the North American short-scale food insecurity assessment. Logistic regression was adopted for the statistical analyses, based on a hierarchical conceptual model that enabled the measurement of the decomposition of the total effect of its non-mediated and mediated components using the proposed hierarchical levels. Results The prevalence of anemia in the studied population was of 21.8%, and the average hemoglobin was 12.06 g/dL (standard deviation [SD]: 1.27). Food insecurity was identified in 28.16% of the pregnant women. The average maternal age was 25.82 years (SD: 5.94). After ranking, the variables positively associated with anemia remained significant: FI (odds ratio [OR] =3.63; 95% confidence interval [95%CI]: 1.77-7.45); not undergoing prenatal care (OR = 5.15;95%CI: 1.43-18.50); multiparity (OR = 2.27;95%CI: 1.02-5.05); and non-supplementation of iron medication (OR = 2.45; 95%CI: 1.04-5.76). The results also indicated that the socioeconomic and environmental factors were largely mediated by food insecurity and factors regarding prenatal care. Conclusions In the present study, the chance of occurrence of anemia in pregnant women was significantly higher,mainly among women: in situations of food insecurity, not undergoing prenatal care, not having received iron supplements, and who are multiparous. Resumo Objetivo Identificar a prevalência de anemia e sua relação com a insegurança alimentar (IA) e outros determinantes em mulheres grávidas. Métodos Trata-se de estudo transversal aninhado a uma coorte, do qual participaram 245 gestantes atendidas em Unidades de Saúde da Família do município de Santo Antônio de Jesus-BA. As participantes foram submetidas a exame de sangue para dosagem de hemoglobina, exame antropométrico, e responderam a um questionário estruturado. Utilizou-se o parâmetro hemoglobina (Hb < 11 g/dL) para a classificação do diagnóstico de anemia. A IA foi avaliada por meio da escala curta norte-americana de avaliação da segurança alimentar. Para as análises estatísticas, adotou-se a regressão logística, tomando-se como base um modelo conceitual hierarquizado definido a priori, que possibilitou a mensuração da decomposição do efeito total em seus componentes não mediados e mediados nos níveis hierárquicos propostos. Resultados A prevalência de anemia na população estudada foi de 21,8%, e amédia de hemoglobina foi de 12,06 g/dL (desvio padrão [DP]: 1,27). A IA foi identificada em 28,16% das gestantes. A média de idade materna foi de 25,82 anos (DP: 5,94). Após a hierarquização, permaneceram significativas as variáveis associadas positivamente à anemia: IA (razão de possibilidades [OR] = 3,63; intervalo de confiança de 95% [IC95%]: 1,77-7,45); não realização de pré-natal (OR = 5,15; IC95%: 1,43-18,50); multiparidade (OR = 2,27; IC95%: 1,02-5,05); e a não suplementaçãomedicamentosa de ferro (OR = 2,45; IC95%: 1,04-5,76). Os resultados indicaram ainda que os fatores socioeconômicos e ambientais forammediados emgrande parte pela IA e pelos fatores de cuidado pré-natal. Conclusões Nesse estudo, a chance de ocorrência de anemia em gestantes foi significantemente maior, principalmente, entre aquelas que estavam em situação de IA, não realizaram o pré-natal, eram multíparas, e não fizeram a suplementação de ferro.

Resumo: Estudo transversal aninhado à coorte prospectiva com o objetivo de avaliar a prevalência e os fatores associados à utilização de medicamentos em gestantes antes e durante a gravidez em município do interior da Bahia, Brasil. As informações foram coletadas mediante um questionário estruturado aplicado às gestantes no momento do acompanhamento pré-natal em unidades de saúde do município. A prevalência para consumo de medicamentos antes e durante a gestação foi 52,1% e 84,7%, respectivamente. Após análise, os seguintes fatores estavam associados à utilização de medicamentos antes da gestação: ≥ 30 anos de idade, as não pretas, as que iniciaram o pré-natal depois do 1º trimestre e as que fazem parte da classe econômica C/D/E. Há um aumento de prevalência de utilização de medicamentos durante a gestação entre as gestantes com escolaridade ≥ 11 anos de estudo, ter feito mais de três consultas pré-natais e ter algum problema de saúde. As gestantes estão expostas ao uso de medicamentos antes e durante a gestação apesar da carência de informações seguras que fundamentem o uso de medicamentos nessa fase, e esse uso está associado a fatores relativos ao acompanhamento pré-natal, sugerindo-se a inclusão mais ativa do farmacêutico na equipe para orientação e apoio ao uso racional de medicamentos. Abstract: This cross-sectional prospective nested cohort study aimed to assess the prevalence of use of medication before and during pregnancy and associated factors in women in a municipality in the countryside of Bahia State, Brazil. Data were collected with a structured questionnaire applied to pregnant women at their prenatal visits at health units. Prevalence rates for use of medication before and during pregnancy were 52.1% and 84.7%, respectively. The following were associated with use of medication before pregnancy: age ≥ 30 years, non-white skin color, first prenatal visit after the 1st trimester, and economic classes C/D/E. There was an increase in medication during pregnancy among women with ≥ 11 years of schooling, women with more than three prenatal visits, and those with some health problem. Pregnant women are exposed to medication before and during pregnancy, notwithstanding the lack of secure information to back the use of medicines during this phase; such use is associated with factors pertaining to prenatal follow-up, suggesting the need for more active participation by pharmacists in orientation and support for rational use of medicines. Resumen: Estudio transversal situado en una cohorte prospectiva, con el objetivo de evaluar la prevalencia y factores asociados a la utilización de medicamentos en gestantes antes y durante el embarazo en un municipio del interior de la región de Bahía, Brasil. La información fue recogida mediante un cuestionario estructurado, aplicado a las embarazadas en el momento del seguimiento prenatal en unidades de salud del municipio. La prevalencia para el consumo de medicamentos antes y durante la gestación fue un 52,1% y un 84,7%, respectivamente. Tras el análisis, los siguientes factores estaban asociados a la utilización de medicamentos antes de la gestación: ≥ 30 años de edad; no afro-brasileñas; quienes comenzaron con el seguimiento prenatal tras el 1º trimestre, y las que forman parte de la clase económica C/D/E. Existe un aumento de prevalencia de utilización de medicamentos durante la gestación entre las gestantes con una escolaridad ≥ 11 años de estudio, haber realizado más de tres consultas prenatales y que tengan algún problema de salud. Las gestantes están expuestas al uso de medicamentos antes y durante la gestación, a pesar de la carencia de información segura que fundamente el uso de medicamentos en esa fase, y ese uso está asociado a factores relativos al seguimiento prenatal, sugiriéndose la inclusión más activa del farmacéutico en el equipo para la orientación y apoyo al uso racional de medicamentos.

OBJECTIVES This study evaluated the associations between single-nucleotide polymorphisms (SNPs) of the vitamin D receptor (VDR) gene, maternal vitamin D concentration, and gestational outcomes. METHODS The cohort consisted of 270 pregnant women who received prenatal services at basic public healthcare centers in the city of Santo Antonio de Jesus, Bahia, Brazil. For statistical analysis, multiple linear regression was used. RESULTS A mean of 72.62 (SD = 31.51) nmol/L for 25-hydroxyvitamin D (25(OH)D) concentrations was found. The mean birth weight was 3.340 g (SD = 0.545 g), and the mean duration of gestation was 38.66 (SD = 1.83) weeks. Pregnant women who were homozygous for the low-frequency allele GG of SNP TaqI had a higher concentration of vitamin D during gestation (β = 14.09 nmol/L; 95% CI = 0.85, 27.34) than the higher frequency homozygotes AA (β = 3.33 nmol/L; 95% CI = -4.37, 11.05). The children of heterozygous women for the ApaI SNP (GA) were born with a lower weight (β = -131.99 g, 95% CI = -258.50, -5.47, P = .04). The heterozygote genotype of the SNP TaqI (CA) decreased the risk of short duration of gestation (β = 0.54 weeks, 95% CI = 0.09, 0.99, P = .01), and the homozygote for the lower frequency allele in the SNP ApaI (CC) showed a negative effect, decreasing the duration of gestation (β = -0.69 weeks, 95% CI = -1.35, -0.26, P = .04). CONCLUSIONS The VDR gene is an important genetic predictor of a higher concentration of vitamin D during gestation, low birth weight, and decreasing duration of gestation.

the nutritional panorama in Brazil indicates that the dietary patterns of the population is characterized by the increasing inclusion of saturated and trans fats, sodium, sugars, soft drinks. This epidemiological and nutritional challenges reflects in the patterns of illness and death.this study aims to identify patterns of food consumption and dietary changes in the first and third trimester of pregnancy.this is a prospective cohort study involving 185 pregnant women in the State of Bahia, from 2012 to 2013. We used a food frequency questionnaire to assess dietary intakes. To identify the dietary pattern, the principal components factor analysis was adopted. We used the Pearson correlation test to identify the correlation between the patterns extracted in each trimester.four patterns of food consumption during pregnancy were identified. We observed changes in the eating patterns over the trimesters evaluated, especially for the food groups of fruit, coffee, fats, fried snacks, sugar and sweets.these dietary changes throughout the pregnancy accompany the physiological changes of each period of the pregnancy. In the first trimester, symptoms of nausea and vomiting are common, whereas in the same period cravings is reported, which may justify the consumption of a larger quantity of food deemed unhealthy.it was observed that there were changes in the adoption of dietary pattern throughout the evaluated trimesters of pregnancy, especially for the groups of fruit, coffee, fats, fried snacks and sugar and sweets.Introducción: las perspectivas de crecimiento en Brasil indican que los patrones dietéticos de la población se caracterizan por el aumento del consumo de grasas saturadas y trans, sodio, azúcares y refrescos. Este punto de vista epidemiológico y nutricional refleja el cambio en el patrón de la enfermedad y la muerte. Objetivo: este estudio tiene como objetivo identificar los patrones de consumo de alimentos y los cambios en la dieta en el primer y tercer trimestres del embarazo. Metodología: se trata de un estudio de cohorte prospectivo de 185 mujeres embarazadas del Estado de Bahía, a partir de 2012 a 2013. Se utilizó el cuestionario de frecuencia de alimentos para evaluar la ingesta alimentaria. Para identificar la norma alimentaria se adoptó el análisis factorial de componentes principales. Se utilizó la prueba de correlación de Pearson para identificar la correlación entre los patrones extraídos en cada trimestre. Resultados: se identificaron cuatro patrones de consumo de alimentos durante el embarazo. Hemos observado cambios en los patrones de alimentación durante los trimestres evaluados, especialmente para los grupos de frutas, café, grasas, frituras, azúcar y dulces. Discusión: estos cambios en la dieta durante el embarazo acompañan a los cambios fisiológicos de cada embarazo. En el primer trimestre son síntomas comunes las náuseas y los vómitos; por otro lado, también se manifiesta antojos en el mismo periodo, lo cual puede justificar el consumo de mayor cantidad de alimentos considerados saludables. Conclusión: se observaron cambios en el patrón alimentario a lo largo de los diversos trimestres del embarazo examinados, especialmente para los grupos de frutas, café, grasas, frituras, azúcar y dulces.
