Effect of Prenatal Care on Perinatal Outcomes of Pregnant Women with Diabetes Mellitus: A Systematic Review.

Objective: to evaluate the effect of prenatal care (PC) on perinatal outcomes of pregnant women with diabetes mellitus (DM). Methods: systematic review developed according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines and conducted through the population, intervention, control, and outcomes (PICO) strategy. Clinical trials and observational studies were selected, with adult pregnant women, single-fetus pregnancy, diagnosis of DM, or gestational DM and who had received PC and/or nutritional therapy (NT). The search was carried out in PubMed, Scopus, and BIREME databases. The quality of the studies was evaluated using the tools of the National Heart, Lung and Blood Institute-National Institutes of Health (NHLBI-NIH). Results: We identified 5972 records, of which 15 (n=47 420 pregnant women) met the eligibility criteria. The most recurrent outcomes were glycemic control (14 studies; n=9096 participants), hypertensive disorders of pregnancy (2; n=39 282), prematurity (6; n=40 163), large for gestational age newborns (4; n=1556), fetal macrosomia (birth weight >4kg) (6; n=2980) and intensive care unit admission (4; n=2022). Conclusions: The findings suggest that PC interferes with the perinatal outcome, being able to reduce the risks of complications associated with this comorbidity through early intervention, especially when the NT is an integral part of this assistance.

Influence of the DASH Diet on Gestational Weight Gain and Perinatal Outcomes in Women with Pre-Existing Diabetes Mellitus: A Randomized, Single-Blind, Controlled Clinical Trial.

BACKGROUND: This study aimed to investigate the influence of the dietary approaches to stop hypertension (DASH) diet on gestational weight gain and perinatal outcomes in pregnant women with pre-existing diabetes mellitus (PDM). METHODS: A randomized, single-blind, controlled clinical trial was conducted with 68 pregnant women with PDM throughout prenatal care until delivery (18 weeks) at a public maternity hospital in Rio de Janeiro, Brazil (2016-2020). The standard diet adopted by the control group (standard diet group-SDG) contained 45-55% carbohydrates, 15-20% protein, and 25-30% lipids of the total energy intake. An adapted DASH diet, with a similar macronutrient composition, but with higher calcium, potassium, magnesium, fiber, and reduced saturated fat, was prescribed for the intervention group (DASH diet group-DDG). Student's t- or Mann-Whitney U tests were used to compare outcomes between groups. To assess the trajectory of gestational weight gain throughout the intervention between the study groups, linear mixed-effects regression models were used. RESULTS: The DDG had lower gestational weight gain at the fifth (p = 0.03) and seventh appointment (p = 0.04), with no difference in average total gestational weight gain (SDG: 10 kg [SD = 4]; DDG: 9 kg [SD = 5], p = 0.23). There was a trend for a lower length of stay of the newborns (p = 0.08) in the DDG without differences for other perinatal outcomes. CONCLUSIONS: The DASH diet promoted less variation in gestational weight gain without promoting a difference in total gestational weight gain, and there was no difference between the study groups for perinatal outcomes.

Effect of the Dietary Approaches to Stop Hypertension (DASH) diet on the development of preeclampsia and metabolic outcomes in pregnant women with pre-existing diabetes mellitus: a randomised, controlled, single-blind trial.

Preeclampsia (PE) affects up to five times more women with pre-existing diabetes mellitus (PDM) than women without it. The present study aimed to identify the effect of the DASH diet on PE incidence (primary outcome) and blood pressure, glycated haemoglobin (GH), serum lipids, glutathione peroxidase (GP), C-reactive protein (CRP - secondary outcomes) in pregnant with PDM. This randomised, controlled, single-blind trial studied sixty-eight pregnant women with PDM throughout prenatal care until delivery (18 weeks) at a public maternity hospital, Brazil. The standard diet group (SDG) received a diet containing 45-65 % carbohydrates, 15-20 % protein and 25-30 % lipids. The DASH diet group (DDG) received the adapted DASH diet with a similar macronutrient distribution, but with a higher concentration of fibres, unsaturated fats, calcium, magnesium and potassium as well as lower saturated fat. Student's t, Mann-Whitney U and the Chi-square tests were used to compare outcomes. PE incidence was 22⋅9 % in the SDG and 12⋅1 % in the DDG (P = 0⋅25). GP levels significantly increased in the DDG (intra-group analysis; mean difference = 1588 [CI 181, 2994], P = 0⋅03) and tended to be different from the variation in the SDG (mean difference = -29⋅5 [CI -1305; 1⋅365]; v. DDG: 1588 [CI 181; 2994], P = 0⋅09). GH levels decreased significantly and similarly between groups (SDG: -0⋅61 [CI -0⋅26, -0⋅96], P = 0⋅00) v. DDG: -1⋅1 [CI -0⋅57, -1⋅62], P = 0⋅00). There was no evidence of a difference in PE incidence at the end of the intervention between the two diets. The DASH diet seems to favour PE-related biochemical markers.

The prevalence and perinatal repercussions of preeclampsia after the implementation of a prophylaxis protocol with aspirin.

OBJECTIVES: To evaluate the prevalence and perinatal repercussions of preeclampsia (PE) after the implementation of a prophylaxis protocol with aspirin in singleton pregnancy at Maternity School of Federal University of Rio de Janeiro, Rio de Janeiro, Brazil (2015-2106). METHODOLOGY: PE prevalence according to gestational age (GA) and the prevalence ratio (PR) between PE and prematurity, small for gestational age (SGA), and fetal death were calculated in patients assisted during 2015 and 2016. RESULTS: PE occurred in 373(10.75%) of 3468 investigated cases, where PE < 37 weeks was of 2.79% and PE greater than 37 weeks was of 7.95%. A total of 413 (11.9%) prematurity cases, 320 SGA (9.22%), and 50 fetal deaths (1.44%) occurred. In the PE group, 97 premature newborns (PR 0.90) and 51 SGA (PR 1.16) were born, and two fetal deaths occurred (PR 7.46). Concerning PE < 37 weeks, 27 SGA cases (PR 1.42) and two fetal deaths (PR 2.62) were observed. Regarding PE greater than 37 weeks, 24 SGA (PR 1.09) were born, and no fetal deaths were observed. Our findings were compared to previously published results. CONCLUSIONS: PE was significantly associated with SGA newborns, especially premature PE. Prescribing aspirin for PE prophylaxis based only on clinical risk factors in a real-life scenario does not appear to be effective but resulted in a PE screening and prophylaxis protocol review and update at ME/UFRJ.

Predictive factors of weight at birth of newborns of adult women with pregestational Diabetes Mellitus : A retrospective observational study.

AIMS: To identify predictive factors of birth weight (BW) of newborns of women with pregestational diabetes mellitus (DM). METHODS: Retrospective observational study with data from pregnant women who started prenatal nutritional monitoring up to 28 weeks, single pregnancy, and BW information. Quantitative variables were analyzed, and mean and standard deviation (SD) measures or medians and interquartile ranges (IQR) were calculated. Predictive factors were identified using multivariate linear regression. RESULTS: Eighty-six pregnant women were analyzed, 50% were diagnosed with type 1 DM, 46.5% with type 2 DM, and 3.5% with unclassified DM; 41% were mixed black and white, 35.6% had overweight and 33.3% had pregestational obesity. The mean BW was 3313.93 g (SD = 696.08). The predictive factors identified were: gestational weight gain (GWG) at the 3rd trimester (ß=60.42; p = 0.04), and gestational age at delivery (ß=194.03; p < 0.001); adjusted by time of diagnosis of DM (p = 0.07) and 1st-trimester glycated hemoglobin (p = 0.71). CONCLUSION: The best predictors of BW were gestational age at birth and maternal anthropometric gestational characteristics, which are modifiable variables. The results may contribute to a review of the prenatal routines of pregnant women with DM.

A Pilot Study of Dietetic, Phenotypic, and Genotypic Features Influencing Hypertensive Disorders of Pregnancy in Women with Pregestational Diabetes Mellitus.

Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal and perinatal morbimortality. Dietetic, phenotypic, and genotypic factors influencing HDP were analyzed during a nutrigenetic trial in Rio de Janeiro, Brazil (2016-2020). Pregnant women with pregestational diabetes mellitus (n = 70) were randomly assigned to a traditional or DASH diet group. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured during prenatal visits and HDP were diagnosed using international criteria. Phenotypic data were obtained from medical records and personal interviews. Genotyping for FTO and ADRB2 polymorphisms used RT-PCR. Linear mixed-effect models and time-to-event analyses were performed. The variables with significant effect on the risk for progression to HDP were: black skin color (adjusted hazard ratio [aHR] 8.63, p = 0.01), preeclampsia in previous pregnancy (aHR 11.66, p < 0.01), SBP ≥ 114 mmHg in the third trimester (aHR 5.56, p 0.04), DBP ≥ 70 mmHg in the first trimester (aHR 70.15, p = 0.03), mean blood pressure > 100 mmHg (aHR 18.42, p = 0.03), and HbA1c ≥ 6.41% in the third trimester (aHR 4.76, p = 0.03). Dietetic and genotypic features had no significant effect on the outcome, although there was limited statistical power to test both.

Gestational weight gain and adverse maternal and perinatal outcomes among women with gestational diabetes mellitus according to International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria: A cross sectional study.

AIMS: To evaluate the association of gestational weight gain and adverse maternal and perinatal outcomes among Brazilian women with gestational diabetes mellitus (GDM). METHODS: Cross-sectional study conducted in women with GDM, and their newborns, who attended a public maternity hospital. The Institute of Medicine criteria were adopted to assess adequacy of gestational weight gain (GWG). Cesarean delivery, maternal hypertensive disorders of pregnancy (HDP), premature birth, macrosomia, and birth weight adequacy for gestational age were analyzed as outcomes. Simple and multiple logistic regression models were tested to assess the effect of adequacy of GWG on maternal and newborn outcomes. RESULTS: Among the 545 women studied, 64.2% (n = 344) had inadequate weight gain: 27.2% (n = 146) insufficient and 37% (n = 198) excessive. Women with insufficient GWG were more likely to have a preterm birth (OR 2.57; 95% CI: 1.06-6.19), while those with excessive GWG had a greater chance of HDP (OR 2.62; 95% CI: 1.54-4.45) and large for gestational age newborn (OR 1.88; 95% CI: 1.08-3.29), compared with those with adequate weight gain. CONCLUSIONS: Inadequate gestational weight gain was frequent in women with GDM, especially in pregnant women with overweight and obesity, and is associated with unfavorable outcomes.

FTO and ADRB2 Genetic Polymorphisms Are Risk Factors for Earlier Excessive Gestational Weight Gain in Pregnant Women with Pregestational Diabetes Mellitus: Results of a Randomized Nutrigenetic Trial.

Excessive gestational weight gain (GWG) is associated with increased risk of maternal and neonatal complications. We investigated obesity-related polymorphisms in the FTO gene (rs9939609, rs17817449) and ADRB2 (rs1042713, rs1042714) as candidate risk factors concerning excessive GWG in pregnant women with pregestational diabetes. This nutrigenetic trial, conducted in Brazil, randomly assigned 70 pregnant women to one of the groups: traditional diet (n = 41) or DASH diet (n = 29). Excessive GWG was the total weight gain above the upper limit of the recommendation, according to the Institute of Medicine guidelines. Genotyping was performed using real-time PCR. Time-to-event analysis was performed to investigate risk factors for progression to excessive GWG. Regardless the type of diet, AT carriers of rs9939609 (FTO) and AA carriers of rs1042713 (ADRB2) had higher risk of earlier exceeding GWG compared to TT (aHR 2.44; CI 95% 1.03-5.78; p = 0.04) and GG (aHR 3.91; CI 95% 1.12-13.70; p = 0.03) genotypes, respectively, as the AG carriers for FTO haplotype rs9939609:rs17817449 compared to TT carriers (aHR 1.79; CI 95% 1.04-3.06; p = 0.02).

Impact of Carbohydrate Counting Method during Pregnancy in Women with Pregestational Diabetes Mellitus: A Controlled Clinical Trial / Impacto do método de contagem de carboidratos em gestantes com diabetes mellitus prévio: Um ensaio clínico controlado

Abstract Objective To evaluate the effect of the carbohydrate counting method (CCM) on glycemic control,maternal, and perinatal outcomes of pregnant women with pregestational diabetes mellitus (DM). Methods Nonrandomized controlled clinical trial performed with 89 pregnant women who had pregestational DMand received prenatal care in a public hospital in Rio de Janeiro, state of Rio de Janeiro, Brazil, between 2009 and 2014, subdivided into historic control group and intervention group, not simultaneous. The intervention group (n=51) received nutritional guidance from the carbohydrate counting method (CCM), and the historical control group (n=38), was guided by the traditionalmethod (TM). The Mann-Whitney test or the Wilcoxon test were used to compare intra- and intergroup outcomes andanalysis of variance (ANOVA) for repeated measures, corrected by the Bonferroni post-hoc test,was used to assess postprandial blood glucose. Results Only the CCM group showed a reduction in fasting blood glucose. Postprandial blood glucose decreased in the 2nd (p=0.00) and 3rd (p=0.00) gestational trimester in the CCM group, while in the TM group the reduction occurred only in the 2nd trimester (p=0.015). For perinatal outcomes and hypertensive disorders of pregnancy, there were no differences between groups. Cesarean delivery was performed in 82% of the pregnant women and was associated with hypertensive disorders (gestational hypertension or pre-eclampsia; p=0.047). Conclusion Both methods of nutritional guidance contributed to the reduction of postprandial glycemia of women and no differences were observed for maternal and perinatal outcomes. However, CCM had a better effect on postprandial glycemia and only this method contributed to reducing fasting blood glucose throughout the intervention.

A gestante e o processo de viver com diabetes mellitus / The pregnant woman and the process of living with diabetes mellitus

Resumo Introdução Gestação está associada à vida e saúde, mas pode acompanhar algum processo de adoecimento, como é o caso do diabetes mellitus, na condição prévia (tipo 1 ou 2) ou gestacional. Compreender a vivência dessas gestantes pode instrumentalizar para a construção de uma proposta de atenção pré-natal especializada e humanizada. Objetivo interpretar os sentidos e significados da gestação com diabetes, sob a perspectiva de mulheres no ciclo gravídico-puerperal. Métodos Estudo de natureza qualitativa com o objetivo de retratar o processo de viver com diabetes mellitus (DM) na gestação, sob a perspectiva das gestantes. Participaram 17 puérperas adultas, com diagnóstico de DM prévio ou gestacional, que realizaram o pré-natal e tiveram seus filhos em uma maternidade pública do Rio de Janeiro. Foram adotadas as técnicas de observação sistemática, bem como entrevistas semiestruturadas e levantamento de dados de prontuário institucional. A interpretação dos dados foi realizada por meio de uma aproximação com o referencial da hermenêutica de profundidade, com adaptação de suas fases, utilizando-se da análise de conteúdo temática, adaptada de Bardin. Resultados Foram identificadas duas categorias, extraídas do corpus das entrevistas: (1) refém do diabetes, relacionando o DM a situações irreversíveis que comprometem a qualidade de vida; e (2) doença da vigilância, associando o DM ao conjunto de medidas terapêuticas necessárias ao seu gerenciamento, como restrição e privação alimentares. Conclusão Concluiu-se que o processo de gestar com DM é permeado por sentidos que merecem ser compreendidos, pois exercem influências sobre o autocuidado e o desfecho da gestação.

Abstract Background Pregnancy is associated with life and health, but it can accompany some illness process, such as diabetes melittus, in the previous (type 1 or 2) or gestational condition. Understanding the experience of these pregnant women can provide instruments for the construction of a proposal for specialized and humanized prenatal care. Objective to interpret the senses and meanings of pregnancy with diabetes, from the perspective of women in the pregnancy-puerperal cycle. Method A qualitative study aimed to bring forward the process of living with diabetes mellitus (DM) during pregnancy, from the perspective of pregnant women. Participants were 17 postpartum women, diagnosed with DM and who underwent prenatal care and had their children in public maternity in Rio de Janeiro. The techniques of systematic observation, semi-structured interviews, and data collection of institutional records were adopted. The interpretation of the data was carried out using an approximation with the reference of the Depth Hermeneutics, with an adaptation of its phases, using Thematic Content Analysis, adapted from Bardin. Results Two categories were identified, extracted from the interview corpus: (1) diabetes hostage, linking DM to irreversible situations that impair quality of life, and (2) disease of surveillance, associating DM with the therapeutic measures necessary for its management, as food restriction and deprivation. Conclusion It was concluded that the process of gestation with DM is permeated by senses, which deserve to be understood since they exert influence on self-care and the outcome of gestation.

Gestational weight gain adequacy for favourable obstetric and neonatal outcomes: A nationwide hospital-based cohort gestational weight gain for favourable obstetric and neonatal outcomes.

BACKGROUND & AIMS: Most Brazilian women fail to gain weight within recommendations during pregnancy but current guidelines about gestational weight gain was based on North American population analysis. There are no standardized recommendations developed from Brazilian population data, which should be particularly analysed due to ethnic and sociodemographic characteristics. This study analyses the gestational weight gain of Brazilian women with favourable obstetric and neonatal outcomes according to the pre-pregnancy body mass index, considering maternal sociodemographic characteristics. METHODS: We analysed data from the Birth in Brazil: national survey into labour and birth study, a nationwide hospital-based cohort carried out in 266 Brazilian hospitals from February/2011 to July 2012, including adult pregnant women who have no chronic diseases and who have single foetal gestation, born alive and without malformation. Favourable obstetric and neonatal outcomes considered were gestational age at birth greater than or equal to 37 and less than 42 weeks, birthweight between 2500 g and 4000 g, and birthweight suitable for gestational age. Sociodemographic characteristics were obtained from medical records and interviews. Weight and height information was obtained from the prenatal card or self-reported. The pre-pregnancy BMI was classified in low weight, normal weight, overweight, obesity I, obesity II, and obesity III. For the missing cases on pre-pregnancy weight or height, body mass index was imputed by multiple imputation prediction model. Gestational weight gain was the difference between the last weight before delivery and the pre-pregnancy weight and was presented as mean and confidence interval, mean and standard deviation, and percentiles distribution (10th to 90th) for each pre-pregnancy body mass index, thus compared to Institute of Medicine recommendations. RESULTS: The analysis included 8184 Brazilian women. The gestational weight gain was lower in women with less favoured social conditions. The mean gestational weight gain according to pre-pregnancy body mass index was within the Institute of Medicine recommendations, except for women with overweight or obesity class I, who have the mean weight gain higher than upper limit of the Institute of Medicine range. Gestational weight gain decreased with an increase in the categories of body mass index; the mean (±standard deviation) were: 15.41 kg (±5.53), 13.54 kg (±4.97), 12.45 kg (±5.86), 9.38 kg (±6.31), 7.15 kg (±6.43), and 5.04 kg (±7.10), for low weight, normal weight, overweight, and obesity I, II and III, respectively. Women had favourable obstetric and neonatal outcomes gaining less, within or more than the recommendations with higher range of variation amongst obesity classes I, II, and III which do not have specific ranges stated in Institute of Medicine guidelines. CONCLUSION: Brazilian women had favourable obstetric and neonatal outcomes gaining less, within or more than the Institute of Medicine recommendations. We highlight the need of population-based high-quality research to investigate the optimal GWG recommendations for this population.

Different methods for assessing gestational weight gain and its association with birth weight. / Diferentes métodos para avaliação do ganho de peso gestacional e sua associação com o peso ao nascer.

OBJECTIVE: To analyze association of different methods of gestational weight gain assessment with live births small for gestational age (SGA) and large for gestational age (LGA). METHODS: This was a cross-sectional study with adult women, normal prepregnancy BMI, single pregnancy and gestational age at delivery ≥28 weeks, from the "Birth in Brazil" study, between 2011 and 2012. RESULTS: Among the 11,000 women participating in the study, prevalence of excessive weight gain was 33.1% according to the Brandão et al. and Institute of Medicine (IOM) methods, and 37.9% according to the Intergrowth method. The chance of being born SGA in the case of insufficient weight gain was OR=1.52 (95%CI 1.06;2.19), OR=1.52 (95%CI 1.05;2.20) and OR=1.56 (95%CI 1.06;2.30) for the Brandão et al., IOM and Intergrowth methods, respectively. Likelihood of excessive weight gain using the same methods was OR=1.53 (95%CI 1.28;1.82), OR=1.57 (95%CI 1.31;1.87) and OR=1.65 (95%CI 1.40;1.96), for LGA respectively. CONCLUSION: Compared to the IOM recommendations, the Intergrowth and Brandão et al. methods show themselves to be alternatives for identifying SGA and LGA.

Effect of ultra-processed foods consumption on glycemic control and gestational weight gain in pregnant with pregestational diabetes mellitus using carbohydrate counting.

AIMS: The aims were to evaluate the consumption of ultra-processed foods by pregnant women with pre-existing diabetes mellitus (DM) using the carbohydrate counting method, in addition to investigating the association with total gestational weight gain and glycemic control. METHODS: A cohort study of adult Brazilian pregnant women with pre-existing DM. Dietary intake was evaluated adopting the NOVA classification to identify the reported consumption of ultra-processed foods. Weight was measured at all consultations and laboratory tests were evaluated at each gestational trimester. Multivariate linear regression was used in the analysis. RESULTS: Pregnant women (n = 42) presented mean total gestational weight gain of 12.02 ± 4.8 kg, 65.8% of them with inadequate weight gain. Daily consumption of ultra-processed foods was 272.37 ± 170.55 kcal. The increase of every 1 kcal in the calorie intake from ultra-processed foods in the third trimester increased glycated hemoglobin by 0.007% (ß = 0.007, p = 0.025), raised 1-h postprandial glucose by 0.14 mg/dL (ß = 0.143, p = 0.011), and added 0.11 kg to total gestational weight gain (ß = 0.11, p = 0.006). CONCLUSION: Ultra-processed food consumption influenced glycemic control and total gestational weight gain in pregnant women with DM.

Impact of the Dietary Approaches to Stop Hypertension (DASH) diet on glycaemic control and consumption of processed and ultraprocessed foods in pregnant women with pre-gestational diabetes mellitus: a randomised clinical trial.

The aim of this study was to evaluate the impact of the Dietary Approaches to Stop Hypertension (DASH) diet on glycaemic control and consumption of processed (PF) and ultraprocessed (UPF) foods in pregnant women with pre-gestational diabetes mellitus (PGDM). This is a randomised, controlled, single-blind clinical trial with forty-nine adult women with PGDM, followed at a public maternity hospital in Rio de Janeiro, Brazil. The control group (CG) received a standard diet consisting of 45-55 % of the total energy intake of carbohydrates, 15-20 % of proteins and 25-30 % of lipids. The DASH group (DG) received an adapted DASH diet, which did not differ from the standard diet in the percentage of macronutrients, but had higher contents of fibre, unsaturated fats and minerals such as Ca, Mg and K; and lower contents of Na and saturated fats than the standard diet. In the analysis by protocol, the DG presented a higher incidence of glycaemic control after 12 weeks of intervention (57·1 v. 8·3 %, P = 0·01, moderate effect size) and a lower mean consumption of UPF (-9·9 %, P = 0·01) compared with the CG. There was no statistically significant difference in fasting and postprandial blood glucose concentrations, or in the consumption of PF between the groups (P > 0·05). The DASH diet may be a strategy for glycaemic control in pregnant women with PGDM, favouring the adoption of a nutritionally adequate diet with lower consumption of UPF. Further studies are needed to investigate the effect of the DASH diet on glycaemic profile, and maternal and perinatal outcomes in women with PGDM.

Associação entre a Assistência Pré-Natal e o Ganho de Peso Gestacional: Estudo Seccional em uma Área de Baixa Renda do Rio de Janeiro / Association between Prenatal Care and Gestational Weight Gain: Cross-Sectional Study in a Low-Income Area of Rio de Janeiro

Objetivo: Verificar a associação entre a adequação da assistência pré-natal e o ganho de peso gestacional (GPG) em puérperas brasileiras de baixa renda. Métodos: Estudo transversal no município de Mesquita-RJ, incluindo 281 mulheres no pós-parto imediato. O GPG foi classificado como adequado, insuficiente e excessivo de acordo com as recomendações do Institute of Medicine (IOM). O número de consultas do prénatal foi categorizado (1: nenhuma consulta; 2: 1-3 consultas; 3: 4-6 consultas; 4: 7 ou mais consultas) e o início do pré-natal, segundo as semanas gestacionais (SG), foi utilizado como variável contínua. A assistência pré-natal (AP) avaliou as duas dimensões agrupadas do Índice de Kotelchuck: adequado (adequado + mais adequado) ou inadequado (intermediário e inadequado). Modelos de regressão logística multinomial foram utilizados para estimar as associações entre assistência pré-natal inadequada e GPG. Resultados: AP foi iniciada em média com 12,6 (± 6,9) SG; 8,2% das mulheres (n = 23) fizeram ≤ 4 consultas de pré-natal e 38,4% (n = 108) foram classificadas com AP inadequada. Em média, o GPG foi de 12,9 kg (± 6,2) e 36,5%, 31,0% e 32,5% das mulheres apresentaram GPG adequado, insuficiente e excessivo, respectivamente. Após o ajuste, a inadequação da AP (OR = 2,01; IC 95% = 1,03-3,90) foi associada a uma maior probabilidade de GPG abaixo das recomendações do IOM. Conclusão: Observou-se uma associação significativa entre a inadequação da assistência pré-natal e o GPG insuficiente, o que reforça a relevância da adequada AP para monitorar o adequado GPG e intervir precocemente na gestação

Aim: To investigate the association between the adequacy of prenatal care and gestational weight gain (GWG) among low-income Brazilian postpartum women. Methods: Cross-sectional study in the city of Mesquita, Rio de Janeiro state, including 281 low-income adult Brazilian postpartum women. GWG was categorized as adequate, insufficient and excessive according to the Institute of Medicine (IOM) recommendations. The number of prenatal visits was categorized (1: no visit; 2: 1-3 visits; 3: 4-6 visits; 4: 7 or more visits) and gestational week (GW) at the onset of prenatal care (prenatal initiation) was used as a continuous variable. Prenatal care (PC) evaluated both grouped dimensions of the Kotelchuck's Index: adequate (adequate + adequate plus) or inadequate (intermediate and inadequate). Multinomial logistic regression models were performed to estimate the associations between inadequate prenatal care and GWG. Results: PC started at 12.6 (± 6.9) GW; 8.2% of women (n=23) had ≤ 4 prenatal visits and 38.4% (n=108) had inadequate PC. On average, GWG was 12.9 kg (±6.2) and 36.5%, 31.0% and 32.5% of women presented adequate, insufficient and excessive GWG, respectively. After adjustment, the inadequacy of PC (OR=2.01; CI 95%=1.03-3.90) was associated with an increased likelihood of gaining weight below IOM recommendations. Conclusion: This study found a significant association between the inadequacy of prenatal care and insufficient GWG, which reinforces the relevance of having adequate PC to provide the opportunity for identification of inadequate GWG and early intervention at pregnancy.

Conclusión: En comparación con las recomendaciones del IOM, Intergrowth y Brandão et.al. se presentan como alternativas en la identificación de PEG y GEG.

Objective: To analyze association of different methods of gestational weight gain assessment with live births small for gestational age (SGA) and large for gestational age (LGA). Methods: This was a cross-sectional study with adult women, normal prepregnancy BMI, single pregnancy and gestational age at delivery ≥28 weeks, from the "Birth in Brazil" study, between 2011 and 2012. Results: Among the 11,000 women participating in the study, prevalence of excessive weight gain was 33.1% according to the Brandão et al. and Institute of Medicine (IOM) methods, and 37.9% according to the Intergrowth method. The chance of being born SGA in the case of insufficient weight gain was OR=1.52 (95%CI 1.06;2.19), OR=1.52 (95%CI 1.05;2.20) and OR=1.56 (95%CI 1.06;2.30) for the Brandão et al., IOM and Intergrowth methods, respectively. Likelihood of excessive weight gain using the same methods was OR=1.53 (95%CI 1.28;1.82), OR=1.57 (95%CI 1.31;1.87) and OR=1.65 (95%CI 1.40;1.96), for LGA respectively. Conclusion: Compared to the IOM recommendations, the Intergrowth and Brandão et al. methods show themselves to be alternatives for identifying SGA and LGA.

Total metal content and chemical speciation analysis of iron, copper, zinc and iodine in human breast milk using high-performance liquid chromatography separation and inductively coupled plasma mass spectrometry detection.

The aim of this research was to quantify essential trace elements (iron, copper, zinc and iodine) and establish their speciation in human milk. Both the element and the species are important in new-born nutrition. Colostrum, and transitional and mature milks (25) were collected from 18 mothers of pre-term or full-term infants. Concentrations of the target elements were determined using ICP-MS. For speciation, HPLC coupled to ICP-MS was employed. Total contents of the micronutrients varied in mothers of pre-term (Fe = 0.997, Cu = 0.506, Zn = 4.15 and I = 0.458 mg L-1) and mothers of full-term (Fe = 0.733, Cu = 0.234, Zn = 2.91 and I = 0.255 mg L-1) infants. Fe, Cu and Zn were associated with biomolecules with high molecular mass compounds, such as immunoglobulins, albumin and lactoferrin whilst iodine was only found as iodide.
