Depression during pregnancy and gestational weight gain: A study of Brazilian pregnant women.

OBJECTIVES: The relationship between psychosocial factors/mental health/depressive symptoms and inadequate gestational weight (GW) change remains poorly understood. Thus, the aim of this study was to evaluate the association between depressive symptoms and inadequate GW change according to the criteria established by the Institute of Medicine in 2009. METHODS: This cross-sectional study was part of a prospective cohort, and conducted in Botucatu, São Paulo, Brazil. Pregnant women who received prenatal care at basic health care units in the city participated in the study (n = 297). The Edinburgh Postnatal Depression Scale was used to assess depressive symptoms during pregnancy, and the cutoff point used for the positive screening of depressive symptoms was ≥13. The association between depressive symptoms and two outcomes (insufficient and excessive weight change during second and third trimesters) was investigated using logistic regression models with adjustment for potential confounders. Crude and adjusted effect measures (odds ratios) and their relevant 95% confidence intervals were estimated. RESULTS: There was an association between a positive score for depression during pregnancy and insufficient GW gain. No association was observed between depressive symptoms and excessive GW gain. CONCLUSIONS: The presence of depressive symptoms significantly increased the chance of insufficient GW change. This finding enhances the need for screening for depression in prenatal care.

Presence of a companion in the delivery room and breastfeeding in the first hour of life: is there an association? / Presença de acompanhante na sala de parto e aleitamento materno na primeira hora de vida: há associação?

Abstract Objectives: to identify variables associated with the presence of a companion in the delivery room and its association with breastfeeding (BF) in the first hour of life. Methods: cross-sectional analysis of data from a cohort study (n=344). To investigate the factors associated with the presence of a companion during childbirth and breastfeeding in the first hour; we performed Poisson regression analyses, considering p<0.05 as the level of statistical significance. Results: 93.9% of the pregnant women had a companion in the delivery room, and no association was found between socioeconomic, obstetric and neonatal characteristics of the mother-child binomial and the presence of a companion. In a univariate analysis, the absence of a companion reduced the frequency of breastfeeding in the first hour (PR=0.64; CI95%=0.42-0.96), a result that was not confirmed in the adjusted analyses (PR=0.79; CI95%=0.54-1.15). Secondly, it was identified that the five minutes Apgar score was associated with first hour breastfeeding (PR=1.27; CI95%=1.14-1.40) regardless of the other factors. Conclusions: most women in the cohort had a companion in the delivery room, with no differences according to socioeconomic, obstetric and neonatal variables. The frequency of first hour breastfeeding was high; however, it was lower in the absence of a companion but this association was not independent of other factors.

Resumo Objetivos: identificar variáveis associadas à presença de acompanhante na sala de parto e sua associação com o aleitamento materno (AM) na primeira hora de vida. Métodos: análise transversal de dados provenientes de um estudo de coorte (n=344). Para investigação dos fatores associados entre a presença de companhia durante o parto e o AM na primeira hora foram realizadas análises de regressão de Poisson, considerando p<0,05 como nível de significância estatística. Resultados: 93,9% das parturientes tiveram acompanhante na sala de parto, não sendo encontrada associação entre características socioeconômicas, obstétricas e neonatais do binômio mãe-filho e esta presença. Em análise univariada, a ausência de acompanhante reduziu a frequência de AM na primeira hora (RP=0,64; IC95%=0,42-0,96), resultado que não se confirmou nas análises ajustadas (RP=0,79; IC95%=0,54-1,15). Secundariamente, identificou-se que o Apgar no quinto minuto associou-se com AM na primeira hora (RP=1,27; IC95%=1,14-1,40) independentemente dos demais fatores. Conclusões: a maioria das mulheres da coorte contou com acompanhante na sala de parto, sem diferenças segundo variáveis socioeconômicas, obstétricas e neonatais. A frequência de AM na primeira hora também foi alta e menor na ausência de acompanhante, contudo, essa associação não se mostrou independente de outros fatores.

Effectiveness of an intervention focusing on diet and walking during pregnancy in the primary health care service.

Interventions during prenatal care can mitigate negative outcomes of a sedentary lifestyle and unhealthy diet during pregnancy. We aimed to evaluate the effectiveness of an intervention that promoted healthy diet and leisure-time walking during antenatal care in a pragmatic, controlled, non-randomized intervention study. Physicians and nurses from all health care units of the Family Health Strategy model of health assistance participated in educational training to promote leisure-time walking and healthy diet during antenatal care visits. Pregnant women who received health care from these professionals constituted the intervention group (n = 181). The control group (n = 172) included pregnant women who received routine antenatal care, in health care units of the traditional model of health assistance. Data were collected in each trimester of pregnancy. Diet was investigated using a food frequency questionnaire adapted from Risk and Protective Factors Surveillance System for Chronic Non-Comunicable Diseases Through Telephone Interview (Vigitel). Leisure-time walking in a typical week was assessed using questions from the Physical Activity in Pregnancy Questionnaire. There were positive effects on leisure-time walking during the second trimester and the third trimester of pregnancy and on the women who achieved 150 minutes per week of walking during the third trimester. The intervention reduced the risk of pregnant women consuming soft drinks and/or commercially prepared cookies in the third trimester. This lifestyle intervention was partially effective, tripling the proportion of pregnant women who achieved the recommended walking time and reducing by half the proportion of women who had a high weekly consumption of soft drinks and industrially processed cookies.

Consumption of ultra-processed foods in the third gestational trimester and increased weight gain: a Brazilian cohort study.

OBJECTIVE: To investigate whether the consumption of ultra-processed foods (UPF) during pregnancy is associated with gestational weight gain (GWG). DESIGN: Cohort study with collection of two 24-h dietary recalls during each gestational trimester obtained on non-consecutive days and differentiating weekday v. weekend/holiday. The foods were classified according to the NOVA system into fresh or minimally processed foods and their culinary preparations, processed and UPF and subsequently analysed as a percentage contribution to dietary energy. The outcome was average GWG in the second and in the third trimesters, expressed in g/week. SETTING: Botucatu, a medium-sized Brazilian city. PARTICIPANTS: Pregnant women with regular obstetric risk (n 259) undergoing prenatal care in primary healthcare. RESULTS: In a multiple linear regression model, it was found that an increase of 1 percentage point in energy consumption from UPF in the third gestational trimester led to an average increase of 4·17 (95 % CI 0·55; 7·79) g in weekly GWG in this period. There was no association between second-trimester UPF consumption and GWG. CONCLUSIONS: Consumption of UPF in the third gestational trimester is positively associated with average weekly GWG in this period.

Resumo: As intervenções durante o acompanhamento pré-natal podem mitigar os desfechos negativos do sedentarismo e da dieta não saudável durante a gravidez. Os autores buscaram avaliar a efetividade de uma intervenção de promoção de dieta saudável e caminhadas no lazer durante o acompanhamento pré-natal, através de um estudo de intervenção pragmático, controlado, não-randomizado. Médicos e enfermeiros de todas as unidades da Estratégia Saúde da Família participaram da capacitação na promoção de caminhadas e diet saudável, como parte do acompanhamento pré-natal. O grupo da intervenção consistia em gestantes que receberam cuidados desses profissionais (n = 181). O grupo controle (n = 172) incluía as gestantes que recebiam os cuidados pré-natais usuais, nas unidades do modelo assistencial tradicional. Os dados eram coletados em cada trimestre da gestação. A dieta era investigada com um questionário de frequência alimentar, adaptado do Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel). As caminhadas no lazer em uma semana típica eram avaliadas com perguntas do Physical Activity in Pregnancy Questionnaire. Houve efeitos positivos sobre o tempo de caminhada no segundo e terceiro trimestres da gestação e nas mulheres que atingiam 150 minutos semanais de caminhadas no terceiro trimestre. A intervenção reduziu o risco de gestantes consumirem refrigerantes e/ou biscoitos industrializados no terceiro trimestre. A intervenção no estilo de vida foi parcialmente efetiva, triplicando a proporção de gestantes que atingiam o tempo recomendado de caminhada e reduzindo pela metade a proporção de mulheres com alto consumo semanal de refrigerantes e biscoitos industrializados.

Resumen: Las intervenciones durante el cuidado prenatal pueden mitigar los resultados negativos de un estilo de vida sedentario y una dieta insana durante el embarazo. Nuestro objetivo fue evaluar la efectividad de una intervención que promovió una dieta saludable y los paseos en el tiempo de ocio, durante el cuidado prenatal, en un estudio pragmático, controlado y de intervención no aleatoria. Médicos y enfermeras de todas las unidades de cuidado de la Estrategia de Salud de la Familia, modelo de asistencia a la salud, participaron en la formación educacional para promover los paseos durante el tiempo de ocio, así como una dieta saludable durante las visitas de cuidado prenatal. Las mujeres embarazadas que recibieron asistencia de estos profesionales constituyeron el grupo de intervención (n = 181). El grupo de control (n = 172) incluyó a mujeres embarazadas, con una rutina de cuidados prenatales, en unidades de atención del modelo tradicional de asistencia en salud. Los datos fueron recabados en cada trimestre de embarazo. La dieta fue investigada usando el cuestionario de frecuencia de comidas adaptado del Vigilancia de Factores de Riesgo y Protección para Enfermedades Crónicas No Transmisibles por Entrevista Telefónica (Vigitel). Los paseos en el tiempo de ocio en una semana típica se evaluaron usando preguntas del Physical Activity in Pregnancy Questionnaire. Hubo efectos positivos por los paseos durante el tiempo de ocio en el segundo y tercer trimestre de embarazo, así como en las mujeres que alcanzaron 150 minutos por semana de paseos durante el tercer trimestre. La intervención redujo el riesgo de mujeres embarazadas que consumían refrescos y/o galletas empaquetadas en el tercer trimestre. La intervención en el estilo de vida fue parcialmente efectiva, triplicando la proporción de mujeres embarazadas que lograron el tiempo de paseos recomendados y redujeron a la mitad la proporción de mujeres que tuvieron una alta frecuencia semanal de consumo de refrescos y galletas procesadas industrialmente.

Insufficient choline intake during pregnancy: cohort study / Ingestão insuficiente de colina durante a gestação: estudo de coorte

ABSTRACT Objective To investigate the intake of choline during pregnancy and associated factors. Methods Cohort study with 353 pregnant women recruited from the primary health care network in an inland city of the State of São Paulo. In-house interviews were conducted in each of the gestational trimesters. In each of these points in time, a 24-hour dietary recall was collected. Subsequently, a new dietary recall collection was performed by telephone in the same trimester on a non-consecutive day, differentiating weekday versus weekend/holiday. Dietary intake data were included in the Nutrition Data System for Research software, and the habitual food intake throughout pregnancy was determined, with intra-individual variation correction in the MSM software. The influence of socioeconomic, obstetric and lifestyle factors, and of the actual diet, on choline intake during pregnancy was assessed using linear regression models, that were developed with the Stata software version 14.2, at a significance level of 95%. Results Choline intake (281.1±68.6 milligrams) was below the recommended adequate intake, and only energy was positively associated with this micronutrient intake. Conclusion Choline intake in the population studied fell far short of current recommendations, and only higher energy intake was found as a factor associated with a higher intake.

Conclusão A ingestão de colina na população estudada ficou muito aquém das recomendações atuais, sendo que apenas a maior ingestão energética foi encontrada como fator associado à maior ingestão de colina.

Longer duration of exclusive breastfeeding reduces maternal weight retention: results from the CLaB study / Maior duração do aleitamento materno exclusivo reduz retenção de peso materno: resultados do estudo CLaB

Abstract Objectives: to evaluate the relation between breastfeeding and postpartum weight reten-tion. Methods: this prospective cohort study involved 641 newborns and their mothers, followed up to twelve months postpartum. Data were collected from June 2015 to February 2017. In the first interview, we investigated data regarding socioeconomic and demographic characteristics, obstetric history, weight, and gestational age of the infant at birth. Maternal weight and breastfeeding status were obtained at 3, 6, 9 and 12 months postpartum at the mother's home. A descriptive analysis of maternal weight retention according to the lactation status was performed. Multiple linear regression models evaluated the effect on exclusive breastfeeding and total breastfeeding duration on maternal weight retention at 6 and 12 months postpartum, considering potential confounders. Results: 512 and 490 mothers were evaluated at six months and at twelve months post-partum, and the mean weight retention was 1.79 (SD=5.52) and 1.69 (SD=6.69) kg, respectively. Regardless of the confounders, the mean postpartum weight reduction for each day of exclusive breastfeeding was 11 (CI95%= -0.019 to -0.003) and 16 grams (CI95%= -0.026 to -0.007) for 6 and 12 months, respectively. The total maternal breastfeeding duration had the same effect. Conclusions: longer periods of exclusive breastfeeding and total breastfeeding are associated with lower postpartum weight retention.

Resumo Objetivos: avaliar a relação entre aleitamento materno e retenção de peso pós-parto. Métodos. estudo de coorte prospectiva com 641 recém-nascidos/mães acompanhados até doze meses pós-parto. Os dados foram coletados de junho/2015 a fevereiro/2017; na primeira entrevista, investigou-se dados socioeconômicos, demográficos, história obstétrica, peso e idade gestacional do lactente ao nascer. Pesos maternos e situação de aleitamento dos lactentes foram obtidos aos 3, 6, 9 e 12 meses pós-parto, em domicílio. Realizou-se análise descritiva da retenção de peso materno segundo situação de aleitamento nesses períodos. Modelos de regressão linear múltiplos avaliaram o efeito da duração do aleitamento materno exclusivo e aleitamento materno sobre retenção de peso materno aos 6 e 12 meses pós-parto, considerando confundidores. Resultados: seis e doze meses pós-parto foram avaliadas 512 e 490 mães, com retenção ponderal média de 1,79 (DP=5,52) e 1,69 (DP=6,69) quilos, respectivamente. Independentemente de confundidores, cada dia a mais de aleitamento materno exclusivo reduziu, em média, 11 (IC95%= -0,019; -0,003) e 16 (IC95%= -0,026; -0,007) gramas a retenção de peso nos dois períodos. A duração do aleitamento materno total teve efeito semelhante. Conclusões: maior duração do aleitamento materno exclusivo e aleitamento materno associam-se com menor retenção de peso pós-parto.

The association of dietary glycaemic index and glycaemic load with gestational weight gain and newborn birth weight.

Diet during pregnancy is related to several maternal and infant health outcomes; however, the relationship between maternal dietary glycaemic index (GI) and glycaemic load (GL) and gestational weight gain (GWG) or newborn birth weight is controversial. The purpose of the present study was to investigate the relationship between maternal dietary GI and GL and GWG and birth weight. A cohort of adult pregnant women with usual obstetric risk was followed in Botucatu, SP, Brazil. Two 24-h dietary recalls were collected in each gestational trimester (<14, 24-27, 31-34 weeks), one in person and the other by telephone. GI and GL were determined using the software Nutrition Data System for Research. GWG was obtained from medical records and evaluated as the weekly GWG between the second and third gestational trimesters. Newborn birth weight z-score in relation to gestational age was evaluated according to Intergrowth-21st Project recommendations. A multiple linear regression model, adjusted for potential confounders, showed a one-point increase in the GI resulted in a mean decrease of 12·9 (95 % CI -21·48, -4·24) g in weekly GWG; GL was not associated with this outcome. The birth weight z-score was not associated with GI (P = 0·763) or GL (P = 0·317). In conclusion, in a cohort of pregnant women considered at usual risk for obstetric complications, maternal dietary GI was negatively associated with weekly GWG in the second and third gestational trimesters. No association was observed between GL and GWG, and neither GI nor GL was associated with birth weight z-score.

[Eating habits of pregnant Brazilian women: an integrative review of the literature]. / Hábitos alimentares das gestantes brasileiras:revisão integrativa da literatura.

The eating habits of pregnant women are influenced by several factors, and it is essential to understand them in order to establish nutritional interventions in prenatal care. The objective of this integrative review was to analyze the bibliographic production on the eating habits of pregnant Brazilian women. A search was conducted in the Biblioteca Virtual em Saúde (BVS), PubMed, Scopus, Web of Science and Scientific Electronic Library Online databases (SciELO) using the following key words: "Gestantes" or "Grávidas" and "Hábitos Alimentares" in Portuguese, and "Pregnant women" and "Eating habits" and "Brazil" in English. After the adoption of inclusion and exclusion criteria, 18 studies were analyzed. Some studies targeted specific populations such as adolescents or non-obese pregnant women. The Food Frequency Questionnaire was the instrument most often used to investigate food consumption among pregnant women. The majority of the studies revealed that the diet of pregnant women needs improvement, especially due to the low consumption of fruit, greens and vegetables, and the high consumption of sugar, sweets and fats. Most studies concluded and reinforced the importance and need for nutritional education by prenatal professionals. More studies are needed to better understand these eating habits.

Os hábitos alimentares das mulheres grávidas são influenciados por diversos fatores, sendo essencial conhecê-los para poder realizar intervenções nutricionais na atenção pré-natal. O objetivo desta revisão integrativa foi analisar a produção bibliográfica sobre hábitos alimentares de gestantes brasileiras. Foram buscados artigos na Biblioteca Virtual em Saúde (BVS), PubMed, Scopus, Web of Science e na Scientific Eletronic Library Online (SciELO) utilizando os seguintes descritores: "Gestantes" OR "Grávidas" AND "Hábitos Alimentares" e os termos "Pregnant women" AND "Food habits" AND "Brazil" para busca em inglês. Após a adoção dos critérios de inclusão e exclusão foram analisados 18 estudos. Alguns estudos contemplaram populações específicas como adolescentes ou gestantes não obesas. O instrumento mais utilizado para investigação do consumo alimentar de gestantes foi o Questionário de Frequência Alimentar. A maioria mostrou que a dieta das gestantes precisa de melhorias, especialmente pelo baixo consumo de frutas, verduras e hortaliças, elevado consumo de açúcares, doces e gorduras. A maioria dos estudos concluiu e reforçou a importância e a necessidade da educação nutricional pelos profissionais atuantes no pré-natal. Mais estudos são necessários para compreensão mais acurada destes hábitos alimentares.

Ultra-processed Food Consumption by Pregnant Women: The Effect of an Educational Intervention with Health Professionals.

Objectives Nutrition during pregnancy is related with many maternal and child outcomes. To investigate the consumption of ultra-processed foods is one of the newest methods to evaluate food consumption, but these studies in pregnant women are rare. Methods We conducted a non-randomized controlled educational intervention on healthy eating and physical activity during pregnancy in primary health care units of Botucatu, São Paulo, Brazil. The sample comprised two groups of pregnant women with low obstetric risk, an intervention group (n = 181) and a control group (n = 172). The health professionals that assisted the pregnant women from the intervention group were trained to promote five healthy food practices during the prenatal care appointments: consumption of three fruits; two portions of vegetables; two portions of beans, at least 5 days per week; and restriction of soft drinks and industrially processed cookies. All pregnant women answered two 24-h dietary recalls per trimester, one face-to-face, another by telephone. The foods consumed by pregnant women were classified according Nova. The impact of the intervention on the ultra-processed food consumption was evaluated by multilevel linear regression analysis. Results A quarter of the energy consumed by the pregnant women provided from ultra-processed foods. The intervention reduced these percentage of energy between the first and second trimester of pregnancy by 4.6 points (p = 0.015). This effect was not observed in the third trimester of pregnancy. Conclusions for Practice Training health care professionals to promote healthy food practices is a viable and sustainable alternative to reduce ultra-processed foods during pregnancy.

Insufficient intake of alpha-linolenic fatty acid (18:3n-3) during pregnancy: and associated factors / Ingestão insuficiente de ácido graxo alfa-linolênico (18:3n-3) durante a gestação: e fatores associados

ABSTRACT Objective: To analyze alpha-linolenic fatty acid intake in two cohorts of pregnant women, and to identify factors associated with alpha-linolenic acid intake. Methods: This is a cohort study involving pregnant women with low obstetric risk (N=353) in public health system from a municipality of São Paulo state, Brazil. In each trimester, two 24-hour food recalls were collected. Descriptive analyses of dietary lipid profiles were performed, followed by a multiple comparison test. According to the trimester of pregnancy, differences were assessed using the mean difference test. To evaluate the adequacy of linoleic fatty acid and alpha-linolenic acid intake, the adequate intake test was used. The association between alpha-linolenic acid intake adequacy and maternal characteristics was investigated using a binary logistic regression model. Results: Total lipids intake and the percentage contribution to dietary energy met recommended levels. One-third of the diets demonstrated a lower than daily recommended intake of alpha-linolenic acid. Overweight pregnant women were twice as likely to have inadequate alpha-linolenic acid intake. Pregnant women from a more disadvantaged socioeconomic situation had greater risks of inadequate intake. Conclusion: Over-intake of lipids is not problematic, but quality is an issue, with one third of the pregnant women and their fetuses exposed to adverse effects due to low intake of omega-3 fatty acids, indicating important nutritional vulnerability in this population.

RESUMO Objetivo: Analisar a ingestão ácidos graxos alfa-linolênico e identificar fatores associados à ingestão inadequada em duas coortes de gestantes acompanhadas trimestralmente. Métodos: Estudo de coorte com gestantes de baixo risco obstétrico (N=353) representativas das usuárias da rede pública de saúde de um município paulista. Nos três trimestres gestacionais foram coletados dois recordatórios alimentares de 24 horas. Análises descritivas do perfil lipídico da dieta foram processadas seguidas do teste de comparações múltiplas. As diferenças, segundo trimestre gestacional, foram avaliadas pelo teste de diferença de médias. Para avaliação da adequação do consumo foi utilizada a ingestão recomendável. A associação entre a adequação da ingestão de ácido alfa-linolênico e características maternas foi investigada por meio de modelo de regressão logística binária. Resultados: A contribuição percentual de lipídeos totais mostrou-se adequada;1/3 das gestantes não alcançou a recomendação de ingestão diária de ácido alfa-linolênico. Gestantes com excesso de peso apresentam o dobro de chances de consumo inadequado de ácido alfa-linolênico. Comparadas às gestantes das classes D/E, as pertencentes a classe C têm menores chances de consumo inadequado. Conclusão: Não há um problema de excesso de consumo de lipídeos e sim da qualidade destes, cerca de 1/3 das gestantes acompanhadas e seus conceptos estão expostos aos efeitos adversos do baixo consumo de ácidos graxos de cadeia ômega-3 na gestação, indicando importante vulnerabilidade nutricional nessa população.

[High prevalence of inadequate calcium and vitamin D dietary intake in two cohorts of pregnant women]. / Alta prevalência de inadequação da ingestão dietética de cálcio e vitamina D em duas coortes de gestantes.

This study aimed to identify the prevalence of inadequate calcium and vitamin D dietary intake and related factors in two cohorts of pregnant women according to trimester of pregnancy. Two 24-hour dietary recall tests were taken in each trimester, one pertaining to weekends. Variables significantly correlated with intake of these nutrients were included in a multivariate linear regression model, adjusted for energy. Prevalence of inadequate intake was estimated according to the National Cancer Institute method (United States). In cohort A, inadequate vitamin D did not differ between trimesters; in B there was a reduction: from 99.7% in the first trimester to 97.1% in the third. In cohorts A and B, inadequate calcium intake exceeded 70%, falling slightly from the first (89.2% and 81.4%) to the second (79.7% and 69.1%) and third trimesters (82.7% and 72.6%). There was no correlation between maternal variables and the intake of these micronutrients. In conclusion, intake of vitamin D and calcium is seriously inadequate and distributed homogeneously among pregnant women in the primary healthcare network.

Alta prevalência de inadequação da ingestão dietética de cálcio e vitamina D em duas coortes de gestantes / High prevalence of inadequate calcium and vitamin D dietary intake in two cohorts of pregnant women / Alta prevalencia de inadecuación en la ingestión dietética de calcio y vitamina D en dos cohortes de gestantes

Este estudo objetivou identificar a prevalência de inadequação da ingestão, por trimestre, de cálcio e vitamina D, em duas coortes de gestantes e fatores correlacionados a esta ingestão. Foram coletados dois recordatórios alimentares de 24 horas em cada trimestre, um relativo a final de semana. Variáveis com correlação significativa com a ingestão desses nutrientes foram incluídas em modelo de regressão linear multivariada, com ajuste por energia. A frequência de inadequação foi estimada pelo método do National Cancer Institute (Estados Unidos). Na coorte A, a inadequação da ingestão de vitamina D não diferiu entre os trimestres; na B, houve redução: 99,7% no 1º para 97,1% no 3º trimestre. Nas coortes A e B, a inadequação da ingestão de cálcio esteve acima de 70%, caindo discretamente do 1º (89,2% e 81,4%) para o 2º (79,7 e 69,1%) e 3º trimestres (82,7% e 72,6%). Não houve correlação entre as variáveis maternas e a ingestão desses micronutrientes. Conclui-se que há um quadro grave de inadequação da ingestão de vitamina D e cálcio, homogeneamente distribuído entre as gestantes assistidas na rede básica de saúde.

En la cohorte A, la inadecuación de la ingestión de vitamina D no difirió entre los trimestres; en la B, hubo reducción: un 99,7% durante el 1º, frente a un 97,1% en el 3º trimestre. En las cohortes A y B, la inadecuación en la ingestión de calcio estuvo por encima de un 70%, cayendo discretamente del 1º (89,2% y 81,4%), al 2º (79,7 y 69,1%) y 3º trimestres (82,7% e 72,6%). No hubo correlación entre las variables maternas y la ingestión de esos micronutrientes. Se concluye que existe un cuadro grave de inadecuación en la ingestión de vitamina D y calcio, homogéneamente distribuido entre las gestantes asistidas por la red básica de salud.

[Eating habits of pregnant and non-pregnant women: are there differences?]. / Práticas alimentares de gestantes e mulheres não grávidas: há diferenças?

PURPOSE: To determine the eating behavior of pregnant women assisted by primary health care and to compare it with women at childbearing age in Brazilian capitals. METHODS: A cross-sectional study conducted on 256 pregnant women in the second trimester of gestation, selected by drawing lots from those assisted by primary health care units of a municipality in the state of São Paulo in 2009/2010. Eating habits were investigated via a questionnaire adapted from the VIGITEL system, consisting of questions about eating habits in general and the frequency and consumption characteristics of food groups/specific foods. For tis comparison, we used the indicators reported by the VIGITEL system for women at childbearing age in Brazilian capitals in 2010. The analyses involved the presentation of frequency distribution and descriptive statistics with comparisons according to the age group. RESULTS: Most patients had breakfast every day (86.7%) and 45.7% habitually exchanged a main meal for a snack once or twice a week. A daily consumption of fruit, raw salad and vegetables was not reported by 48.8%, 41.8% and 55.1% of the women, respectively. Fish was reported to never or almost never be consumed by 64.4% of the pregnant women. At least once a week, 69.9% of them reported the consumption of soda, and 86.4% of wafers/cookies. The comparison between the pregnant women and women at childbearing age in capitals showed a close similar prevalence of overweight, and no difference in the regular consumption of fruit and vegetables. Meat containing excess of fat and whole milk were more consumed by pregnant women, with differences reported in all the age groups analyzed. On the other hand, the pregnant women reported a less regular intake of soft drinks. CONCLUSIONS: The actions that need to be performed in prenatal care are various and very important, promoting the consumption of specific foods and providing guidelines about eating behavior, while reinforcing healthy eating habits already present.

Práticas alimentares de gestantes e mulheres não grávidas: há diferenças? / Eating habits of pregnant and non-pregnant women: are there differences?

OBJETIVOS: Conhecer o comportamento alimentar de gestantes assistidas pela atenção primária à saúde e compará-lo ao de mulheres em idade fértil das capitais brasileiras. MÉTODOS: Estudo transversal realizado no segundo trimestre gestacional com 256 gestantes, sorteadas dentre as assistidas pelas unidades de atenção primária à saúde de um município do interior paulista em 2009/2010. As práticas alimentares foram investigadas utilizando questionário adaptado do sistema Vigitel, composto por questões acerca de comportamentos alimentares em geral e frequência e características de consumo de grupos alimentares/alimentos específicos. Para a comparação foram utilizados os indicadores reportados pelo sistema Vigitel para as mulheres em idade fértil das capitais brasileiras no ano de 2010. As análises envolveram a apresentação de distribuição de frequências e estatísticas descritivas (distribuição de frequências ou médias e respectivos intervalos de confiança) com comparações de acordo com faixa etária. RESULTADOS: A maioria das gestantes consumia o café da manhã todos os dias (86,7%); a troca da refeição principal por lanche uma ou duas vezes por semana era o hábito de 45,7%. O consumo diário de frutas, salada crua, verduras e legumes não ocorria, respectivamente, em 48,8, 41,8 e 55,1% das gestantes. Peixe foi relatado como nunca ou quase nunca consumido por 64,4% das gestantes. Pelo menos uma vez por semana, 69,9% delas relataram consumo de refrigerante e 86,4% de bolacha/biscoito. Comparando as gestantes e mulheres em idade fértil das capitais brasileiras, a prevalência de excesso de peso foi bastante parecida e não houve diferenças entre o consumo regular de frutas e hortaliças. Carne com excesso de gordura e leite integral foram mais consumidos pelas gestantes, com diferenças em todas as faixas etárias analisadas. Por outro lado, gestantes tiveram menor ingestão regular de refrigerantes. CONCLUSÕES: Devem ser variadas e de grande importância ...

Early and late pregnant adolescents and neonatal results: a cohort study / Adolescentes embarazadas precoces y tardías y resultados neonatales: estudio de cohorte / Gestantes adolescentes precoces e tardias e resultados neonatais: estudo de coorte

Aim: To identify the profile of precocious (under 16 years of age) and late pregnant adolescents (17-19 years) by comparing neonatal results. Method: This is a unique cohort in which potential confounders of a biological and socio-demographic nature were identified (p<0.05), with subsequent analysis of adverse neonatal results in both studied groups, using the chi-square test. Results: We identified differences in the workplace, first pregnancy, income, labor in the Unified Health System, and cohabitation with a partner. Low Apgar scores and respiratory disorders were more frequent in early adolescents. The need for resuscitation and admission to an intensive care unit did not differ between groups. Discussion: The studied adolescents revealed that they live in social risk. A relationship was found between Apgar scores and respiratory disorders in the fetuses of early adolescents. Conclusion: We suggest the need for investment to prevent pregnancy in this age group, and for prenatal care and skilled birth support, especially for precocious adolescents.

Objetivo:Identificar el perfil de las adolescentes embarazadas precoces (hasta 16 años) y tardías de (17-19 años),comparando los resultados neonatales.Métodos: Se trata de cohorte único en que fueron identificados potenciales de factores de confución de naturaleza biológica y sociodemográfica ( p<0,05), con un análisis posterior de resultados de neonatal adversos en los dos grupos estudiados, desde la prueba qui-cuadrado. Resultados: Se identificaron diferencias relativas al trabajo,del primer embarazo, ingresos,parto en el SUS y convivencia con compañero. Bajos índices de Apgar y trastornos respiratorios fueron más frecuentes en adolescentes precoces. La necesidad de reanimación e internación en la unidad de terapia intensiva no fue diferido entre los grupos. Discusión: Las adolescentes estudiadas mostraron estar en riesgo social. Se encontró una relación entre índices de Apgar y trastornos respiratorios en los conceptos de adolescentes precoces. Conclusión: Se sugieren inversiones para la prevención del embarazo en esta edad, asistencia prenatal y al parto calificado, especialmente para adolescentes precoces.

Sobrepeso pré-gestacional associa-se a ganho ponderal excessivo na gestação / Prepregnancy overweight is associated with excessive weight gain during pregnancy

OBJETIVOS: Avaliar a adequação do ganho ponderal gestacional e verificar sua associação com fatores socioeconômicos, demográficos e nutricionais maternos e relativos à atenção à saúde e estimar a prevalência de baixo peso ao nascer, macrossomia, prematuridade e parto cesárea e identificar a associação desses desfechos com adequação do ganho ponderal. MÉTODOS: Estudo transversal realizado em 2009/2010 forneceu dados socioeconômicos, demográficos, nutricionais, alimentares e sobre atividade física de gestantes assistidas na atenção primária à saúde de município paulista. Posteriormente, foram coletados nos prontuários dados de peso para avaliar o ganho ponderal gestacional. No Sistema de Informações de Nascidos Vivos obtiveram-se tipo de parto, peso e idade gestacional do concepto ao nascer. O ganho ponderal gestacional foi avaliado segundo recomendações do Institute of Medicine (2009). As associações foram investigadas mediante comparação de frequências e regressão logística, sendo ganho ponderal excessivo (sim, não) e ganho insuficiente (sim, não) as variáveis dependentes. RESULTADOS: Foram estudadas 212 gestantes: 50,5% apresentaram ganho excessivo e 19,8%, insuficiente. Apenas estado nutricional pré-gestacional associou-se com adequação do ganho ponderal: na comparação com eutróficas, o sobrepeso pré-gestacional quadruplicou a chance de ganho excessivo (OR 4,66; IC95% 2,19-9,4). Quase um terço dos conceptos nasceu de cesariana, 5,7%, prematuros, 7,1%, com baixo peso e 4,7%, macrossômicos. Não houve associação entre adequação do ganho ponderal gestacional e tais desfechos. CONCLUSÕES: É alta a proporção de ganho ponderal gestacional inadequado. Gestantes com sobrepeso têm sua chance de ganho excessivo quadruplicada, devendo ser priorizadas em ações de promoção do ganho de peso adequado no pré-natal.

PURPOSE: To evaluate the adequacy of gestational weight gain and to determine its association with maternal socioeconomic, demographic and nutritional factors and health care, to estimate the prevalence of low birth weight, macrosomia, preterm birth and cesarean delivery and to identify the association of these outcomes with the adequacy of weight gain. METHODS: A cross-sectional study was performed in 2009/2010 to obtain socioeconomic, demographic, nutritional, dietary and physical activity data of pregnant women assisted by primary health care in a municipality of the state of São Paulo. Subsequently, data were collected from the medical records to evaluate gestational weight gain. Type of delivery, birth weight and gestational age at delivery were obtained from the Livebirths Information System. Gestational weight gain was evaluated according to the recommendations of the Institute of Medicine (2009). Associations were investigated by comparing the frequencies and by logistic regression, with excessive weight gain (yes, no) and insufficient gain (yes, no) being the dependent variables. RESULTS: A total of 212 pregnant women were studied: 50.5% had excessive gain and 19.8% insufficient weight gain. Only prepregnancy nutritional status was associated with adequacy of weight gain: compared with normal weight, prepregnancy overweight women had a four-fold higher chance to gain excessive weight (OR 4.66, 95%CI 2.19-9.4). Nearly a third of babies were born by caesarian section, 5.7% were premature, 7.1% were underweight and 4.7% were macrosomic. There was no association between adequacy of gestational weight gain and these outcomes. CONCLUSION: The proportion of inadequate gestational weight gain was high. Overweight pregnant women have a four-fold higher chance to gain excessive weight, and priority should be given to actions promoting adequate prenatal weight gain.
