Mobile Application Increased Nutrition Knowledge Among Brazilian Physicians.

OBJECTIVE: To assess whether using a Dietary Approaches to Stop Hypertension (DASH) diet recommendation application increases primary care physicians' knowledge and dietary counseling skills. DESIGN: A randomized controlled trial. SETTING: Brazilian public primary care service. PARTICIPANTS: Two hundred and twenty-two physicians (intervention group: n = 111; control group: n = 111). INTERVENTION: Thirty days of using the Dieta Dash application. The application provides information about nutritional recommendations for hypertension management. MAIN OUTCOME MEASURES: Nutrition knowledge score. SECONDARY OUTCOMES: self-assessment of knowledge, self-confidence, assessment of eating habits, and barriers to dietary counseling. ANALYSIS: Linear mixed-effects models for repeated measures and generalized estimating equations for comparing changes between groups. RESULTS: A total of 66.2% of participants completed the follow-up. There was no significant difference between the groups regarding the mean knowledge score (P = 0.15). The prevalence of high knowledge increased by 12% (prevalence ratio [PR] = 1.12; 95% confidence interval [CI], 1.00-1.25) in the intervention group and showed an improvement in the self-confidence assessment (PR = 1.21; 95% CI, 1.02-1.44), and increased assessment of eating habits (PR = 1.26; 95% CI, 1.10-1.55). CONCLUSIONS AND IMPLICATIONS: The Dieta Dash application helped address dietary counseling, improving knowledge and self-confidence. However, innovative strategies are needed to minimize the primary care barriers.

Dietary Patterns in Pregnancy and the Postpartum Period and the Relationship with Maternal Weight up to One Year after Pregnancy Complicated by Gestational Diabetes.

This multicentric cohort study aimed to describe changes in dietary patterns during pregnancy and postpartum and the association with BMI variation at six and twelve months postpartum in women with gestational diabetes mellitus (GDM). Between 2014 and 2018, we enrolled women with GDM in prenatal clinics of the Brazilian National Health System and followed them for one year postpartum. The dietary patterns during pregnancy and the postpartum period were obtained by factorial analysis. The relationship between these patterns and variation in postpartum BMI was evaluated by Poisson regression with robust variance adjusted for confounders. We identified three dietary patterns in 584 women, two healthy (generally healthy and Dash type), which were associated with less weight gain (RR 0.77 CI 95% 0.62-0.96 and RR 0.71 CI 95% 0.57-0.88, respectively). The high-risk pattern (based on ultra-processed, high-calorie foods and sweetened drinks) was associated with weight gain (RR 1.31 CI 95% 1.07-1.61 and RR 1.26 CI 95% 1.01-1.59) in six and twelve months postpartum, respectively. Although the participants learned about healthy dieting during pregnancy, dietary habits worsened from pregnancy to postpartum, especially, with lower consumption of fruits and dairy and higher consumption of sweetened beverages, with consequent weight gain postpartum. Postpartum support is needed to prevent weight gain and obesity.

Association between dairy products consumption and the prevalences of combined prediabetes and type 2 diabetes mellitus in Brazilian adolescents: a cross-sectional study.

The association between dairy products consumption in adults and the likelihood of type 2 diabetes mellitus (T2DM) has been described, but more information on the adolescent population is needed. This nationally representative, cross-sectional school-based study aimed to describe the consumption of dairy products and their subtypes and to evaluate their association with prediabetes and T2DM in adolescents. The Study of Cardiovascular Risks in Adolescents (ERICA) includes adolescents aged 12-17 years. Dairy products consumption was evaluated by 24-h food recall. Associations with fasting glucose, glycated hemoglobin (HbA1c) and insulin resistance, as measured by homeostatic model assessment-insulin resistance (HOMA-IR), were evaluated by multivariate linear regression. Poisson regression was also used to assess the association between dairy products consumption and the combined prevalence of prediabetes and T2DM. Models were adjusted for sociodemographic, nutritional, behavioural and anthropometrics. The final sample analysed consisted of 35 614 adolescents. Total intake of dairy products was inversely associated with fasting blood glucose levels after adjusting for all covariates (ß = -0·452, 95 % CI -0·899, -0·005). The associations were stronger for overweight and obese adolescents. Findings were similar for full-fat dairy products and yogurt. Higher consumption of low-fat dairy products and cheese were associated with a 46 % (prevalence ratio, PR 1·46, 95 % CI 1·18, 1·80) and 33 % (PR 1·33, 95 % CI 1·14, 1·57) higher combined prevalence of prediabetes and T2DM, respectively. The total consumption of dairy products and full-fat dairy products was associated with a lower combined prevalence of prediabetes and T2DM, while the consumption of cheese and low-fat dairy products was associated with higher combined prevalence of prediabetes and T2DM in Brazilian adolescents.

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.

Association between breastfeeding and complementary feeding in pre-pandemic and pandemic COVID-19 times: Maternar cohort study

Abstract Objective Evaluate the association between breastfeeding, exclusive breastfeeding at six months and the introduction of complementary feeding during the pre-pandemic and the COVID-19 pandemic periods. Methods Cohort study conducted with puerperal women and their newborns in the immediate postpartum period at a reference maternity hospital in Southern Brazil between 2018-2020. The COVID-19 pandemic period and the need to work outside the home during restricted circulation were the factors of exposure. The outcome evaluated was the weaning in the first six months (breastfeeding and exclusive breastfeeding) and the introduction of complementary feeding before the sixth month of life. Results 547 puerperal women and their newborns were included. During the COVID-19 pandemic, there was a higher risk to weaning of exclusive breastfeeding up until six months (RR 1.16; 95%CI 1.03-1.31) and introducing complementary feeding early (RR 1.40; 95%CI 1.01-1.96). The need to work outside the home during the COVID-19 pandemic increased the risk of not breastfeeding exclusively at the sixth month (RR 1.27; 95%CI 1.08-1.49). Conclusions The difficulties of the pandemic did reflect negatively on breastfeeding and complementary feeding practices. The pandemic was a risk factor for the early weaning of exclusive breastfeeding and the introduction of complementary feeding. However, not having to work outside the home during the pandemic period was a protective factor for exclusive breastfeeding at six months.

Breastfeeding Rates and Related Factors at 1 Year Postpartum in Women With Gestational Diabetes Initially Recruited for a Diabetes Prevention Program.

OBJECTIVES: Our aim in this study was to evaluate breastfeeding up to 1 year postpartum and factors related to weaning in women with recent gestational diabetes mellitus (GDM). METHODS: We assembled a cohort study of women with GDM enrolled in prenatal clinics of the Brazilian National Health System as possible candidates for the Lifestyle Intervention for Diabetes Prevention After Pregnancy (LINDA-Brasil) postpartum trial (N=2,220). Sociodemographics and clinical and nutritional information, including breastfeeding, were obtained by interview or chart review. Follow-up by telephone was done at specific intervals during the first year postpartum. RESULTS: The probability of breastfeeding at 1 year postpartum, estimated from Kaplan-Meier survival analysis, was 53.5%. Cox regression models showed increased risk of weaning for those introducing milk or formula before 6 months (hazard ratio [HR], 2.55; 95% confidence interval [CI], 2.10 to 3.09); reporting problems in breastfeeding (HR, 1.49; 95% CI, 1.22 to 1.82); being Caucasian (HR, 1.46; 95% CI, 1.21 to 1.76); smoking during pregnancy (HR, 1.68; 95% CI, 1.28 to 2.20); and living in 2 southern cities of Brazil (HR, 1.58; 95% CI, 1.16 to 2.16; and HR, 1.76; 95% CI, 1.20 to 2.58). CONCLUSIONS: About half of the women with GDM ceased breastfeeding before 1 year postpartum, a rate matching that of the general population in Brazil. The main risk factor was not exclusively breastfeeding up to 6 months. Given the possibility of curbing diabetes risk by maintaining longer breastfeeding, further promotion of exclusive breastfeeding up to 6 months for these high-risk women is much needed.

Adequacy of prenatal care considering nutritional assistance in Southern Brazil: Maternar Cohort Study.

We verified the prevalence of adequacy in prenatal care considering nutritional assistance and associated factors. It is a cross-sectional study, part of Maternar Cohort Study, conducted between 2018-2019 in Southern Brazil. Women were interviewed during hospitalization in the immediate postpartum period and data were collected from the prenatal chart. Prenatal adequacy and nutritional care were assessed according to criteria from the Brazilian Ministry of Health. Two outcome models were constructed. Outcome 1 consisted of minimal coverage (early prenatal start and minimum number of visits) and exams, and Outcome 2 comprised minimal coverage, exams, and nutritional assistance. Poisson regression was used to estimate prevalence ratios. A total of 802 women were analyzed, and we identified 57% of adequacy of Outcome 1. Unplanned pregnancy (PR = 0.76; 95%CI: 0.68-0.86), parity (PR = 0.88; 95%CI: 0.83-0.94) and prenatal care outside Porto Alegre, Rio Grande do Sul State (PR = 0.80; 95%CI: 0.69-0.92), were associated with lower prenatal adequacy frequencies. Outcome 2 was considered adequate for 10.2% of women. Follow-up by different professionals during prenatal care was associated with lower adequacy (PR = 0.49; 95%CI: 0.28-0.86). Women with high-risk pregnancies had a higher frequency of adequacy in Outcome 1 (PR = 1.21; 95%CI: 1.07-1.37) and in Outcome 2 (PR = 1.75; 95%CI: 1.16-2.64). General adequacy was considered low in both outcomes. There was a lack of nutritional assistance during prenatal care. Characteristics such as pregnancy planning, lower parity, prenatal care in Porto Alegre, follow-up by the same professional and high-risk pregnancy were predictors for the adequacy of prenatal care.

Sociodemographic and obstetric factors associated with the interruption of breastfeeding within 45 days postpartum - Maternar Cohort Study / Fatores sociodemográficos e obstétricos associados à interrupção do aleitamento materno em até 45 dias pós-parto - Estudo de Coorte Maternar

Abstract Objectives: to evaluate and identify the prevalence of interruption of breastfeeding (BF) in the period of up to 45 days postpartum and the associated sociodemographic and obstetric factors. Methods: cohort of 622 puerperal women, selected between 2018 and 2019 in a reference maternity hospital in the South Brazil. Data collection was carried out in two phases, the first in the maternity hospital during hospitalization of the puerperal woman and the newborn and the second through a telephone call, which occurred 60 days after birth. Poisson regressions with robust variance were performed to identify the factors associated with interruption of BF in the first 45 days of life. The variables that presented p<0.20 in the crude analysis were included in the adjusted analysis. Results: the interruption of BF at 45 days was identified in 14% of the sample. Higher maternal age (PR= 0.46; CI95%= 0.22-0.93), eight years or less of education (PR= 2.11; CI95%= 1.05-4.25), support from the maternal grandmother (PR= 1.91; CI95%= 1.20-3.06) and receiving complement at the maternity hospital (PR= 1.53; CI95%= 1.04-2.25) were factors related to the interruption of BF in the 45-day postpartum period. Conclusion: maternal age ≥35 was a protective factor, and less education, the support of the maternal grandmother and receiving complement at the maternity hospital were predictors of early breastfeeding abandonment.

Resumo Objetivos: identificar a prevalência de interrupção do aleitamento materno (AM) no período de até 45 dias pós-parto e avaliar os fatores sociodemográficos e obstétricos associados. Métodos: coorte com 622 puérperas, selecionadas entre 2018-2019 em uma maternidade de referência do sul do Brasil. A coleta dos dados foi realizada em duas fases, a primeira na maternidade durante internação da puérpera e do recém-nascido e a segunda através de ligação telefônica, ocorrida após 60 dias do nascimento. Regressões de Poisson com variância robusta foram realizadas para identificar os fatores associados com a interrupção do AM nos primeiros 45 dias de vida. As variáveis que apresentaram p<0,20 na análise bruta foram inseridas na análise ajustada. Resultados: a interrupção do AM aos 45 dias foi identificada em 14% da amostra. Maior idade materna (RP= 0,46; IC95%= 0,22-0,93),oito anos ou menos de escolaridade (RP= 2,11; IC95%= 1,05-4,25), apoio da avó materna (RP= 1,91; IC95%= 1,20-3,06) e recebimento de complemento na maternidade (RP= 1,53; IC95%= 1,04-2,25) foram fatores relacionados com a interrupção do AM no período de 45 dias pós-parto. Conclusão: a idade materna ≥35 foi um fator protetor e a menor escolaridade, o apoio da avó materna e o recebimento de complemento na maternidade foram preditores do abandono precoce do AM.

Obesity, gestational weight gain, and birth weight in women with gestational diabetes: the LINDA-Brasil (2014-2017) and the EBDG (1991-1995) studies.

OBJECTIVE: This study aimed to evaluate gestational weight gain and birth weight in women with gestational diabetes mellitus of two Brazilian cohorts enrolled three decades apart. METHODS: The authors compared data of 2362 women from the Lifestyle INtervention for Diabetes Prevention After Pregnancy study (LINDA-Brasil, 2014-2017) to those of 359 women from the Estudo Brasileiro de Diabetes Gestacional study (EBDG, 1991-1995). Gestational weight gain was classified by the 2009 Institute of Medicine criteria; large and small for gestational age newborns, by the Intergrowth-21st chart. Differences in birth weight means between pregestational BMI and gestational weight gain categories were evaluated by ANOVA; the associations of gestational weight gain and birth weight, through multivariable Poisson regression. RESULTS: In LINDA-Brasil, women presented higher pregestational body mass index (30.3±6.5 vs. 24.6±4.4kg/m2) and were frequently obese (46.4 vs. 11.1%) compared to those of the EBDG. In the EBDG, gestational weight gain was larger (11.3±6.1 vs. 9.2±7.6kg) and rates of small for gestational age higher (7.5 vs. 4.5%) compared to LINDA-Brasil. In LINDA-Brasil, excessive gestational weight gain was associated to macrosomia (adjusted relative risk [aRR]: 1.59, 95% CI 1.08-2.35) and large for gestational age (aRR: 1.40; 95% CI 1.05-1.86); less gain increased the risk of low birth weight (aRR: 1.66; 95% CI 1.05-2.62) and small for gestational age (aRR: 1.79; 95% CI 1.03-3.11). These associations were similar in the EBDG, although not statistically significant. CONCLUSIONS: Improvements in gestational weight gain and rates of small for gestational age occurred over time in gestational diabetes mellitus pregnancies, accompanied by a worsening in maternal weight profile. This highlights the nutritional transition during this period and the importance of avoiding excessive gestational weight gain as well as promoting adequate weight before conception.

Effect of a healthy eating intervention in the first months of life on ultraprocessed food consumption at the age of 4-7 years: a randomised clinical trial with adolescent mothers and their infants.

This randomised clinical trial aimed to evaluate the effect of a pro-breast-feeding (BF) and healthy complementary feeding intervention performed during infants' first months of life on ultraprocessed food (UPF) consumption at 4-7 years. We enrolled 323 teenage mothers and their infants from South Brazil, 163 allocated to the intervention group and 160 to the control group. Intervention consisted of sessions on BF and healthy complementary feeding promotion and was carried out in the maternity ward and at home after delivery. Food consumption was assessed using three 24-h food recalls at child's age of 4-7 years. Foods were classified according to NOVA classification. Dietary contribution of UPF was adjusted for intra-individual variability by the SPADE method and categorised into tertiles. We used Poisson regression models with robust variance, adjusted for confounders, to estimate the effect of the intervention and duration of BF on the risk of high consumption of UPF. Our final analysis included 194 children, with mean age of 6·1 (sd 0·5) years. Mean dietary contribution of UPF was 38 % in the intervention group and 42·7 % in the control group, from total daily intakes. Results adjusted for BF duration, propensity score, income and total energy content demonstrated that the intervention reduced the risk of high consumption of UPF by 35 % (relative risk 0·65, 95 % CI 0·43, 0·98). BF duration was not associated with UPF consumption. The intervention was effective in reducing the risk of high UPF consumption at the age of 4-7 years.

Adequacy of prenatal care considering nutritional assistance in Southern Brazil: Maternar Cohort Study / Adequação de cuidados pré-natais e assistência nutricional no Sul do Brasil: o Estudo de Coorte Maternar / Adecuación del cuidado prenatal considerando la asistencia nutricional en el sur de Brasil: Estudio de Cohorte Maternar

Abstract: We verified the prevalence of adequacy in prenatal care considering nutritional assistance and associated factors. It is a cross-sectional study, part of Maternar Cohort Study, conducted between 2018-2019 in Southern Brazil. Women were interviewed during hospitalization in the immediate postpartum period and data were collected from the prenatal chart. Prenatal adequacy and nutritional care were assessed according to criteria from the Brazilian Ministry of Health. Two outcome models were constructed. Outcome 1 consisted of minimal coverage (early prenatal start and minimum number of visits) and exams, and Outcome 2 comprised minimal coverage, exams, and nutritional assistance. Poisson regression was used to estimate prevalence ratios. A total of 802 women were analyzed, and we identified 57% of adequacy of Outcome 1. Unplanned pregnancy (PR = 0.76; 95%CI: 0.68-0.86), parity (PR = 0.88; 95%CI: 0.83-0.94) and prenatal care outside Porto Alegre, Rio Grande do Sul State (PR = 0.80; 95%CI: 0.69-0.92), were associated with lower prenatal adequacy frequencies. Outcome 2 was considered adequate for 10.2% of women. Follow-up by different professionals during prenatal care was associated with lower adequacy (PR = 0.49; 95%CI: 0.28-0.86). Women with high-risk pregnancies had a higher frequency of adequacy in Outcome 1 (PR = 1.21; 95%CI: 1.07-1.37) and in Outcome 2 (PR = 1.75; 95%CI: 1.16-2.64). General adequacy was considered low in both outcomes. There was a lack of nutritional assistance during prenatal care. Characteristics such as pregnancy planning, lower parity, prenatal care in Porto Alegre, follow-up by the same professional and high-risk pregnancy were predictors for the adequacy of prenatal care.

Resumo: Verificamos a prevalência de adequação da atenção pré-natal considerando a assistência nutricional e identificamos os fatores associados. O estudo transversal, parte do Estudo de Coorte Maternar, foi realizado em 2018 e 2019 no Sul do Brasil. As mulheres foram entrevistadas durante a internação no pós-parto imediato, e os dados foram coletados do cartão de pré-natal. A adequação do pré-natal e da assistência nutricional foram avaliadas de acordo com os critérios do Ministério da Saúde. Dois modelos de desfechos foram construídos. O Desfecho 1 consistia em cobertura mínima (início precoce do pré-natal e número mínimo de consultas) e exames, e o Desfecho 2, com cobertura mínima e exames, acrescidos de assistência nutricional. Foi utilizada a regressão de Poisson para estimar as razões de prevalência. Foram analisadas 802 mulheres, e identificamos 57% de adequação do Desfecho 1. A gravidez não planejada (RP = 0,76; IC95% 0,68-0,86), paridade (RP = 0,88; IC95%: 0,83-0,94) e pré-natal fora da capital do Estado do Rio Grande do Sul (RP = 0,80; IC95%: 0,69-0,92) estiveram associados a menores frequências de pré-natal adequado. O Desfecho 2 foi considerado adequado em 10,2% das mulheres. O acompanhamento por diferentes profissionais durante o pré-natal esteve associado a menor adequação (RP = 0,49; IC95%: 0,28-0,86). As mulheres com gravidez de alto risco tiveram maior frequência de adequação no Desfecho 1 (RP = 1,21; IC95%: 1,07-1,37) e no Desfecho 2 (RP = 1,75; IC95%: 1,16-2,64). A adequação geral foi considerada baixa para ambos os desfechos. Havia falta de assistência nutricional durante o atendimento pré-natal. Os preditores de adequação do pré-natal incluíam planejamento da gravidez, paridade menor, pré-natal na capital, acompanhamento pelo mesmo profissional e gestação de alto risco.

Resumen: Verificamos la prevalencia de la adecuación del cuidado prenatal, considerando factores relacionados con la asistencia nutricional, así como sus factores asociados. Se trata de un estudio trasversal, que parte del Estudio de Cohorte Maternar, realizada entre 2018-2019 en el sur de Brasil. Las mujeres fueron entrevistadas durante su hospitalización en un período inmediato al postparto y los datos se recogieron de la cartilla prenatal. La adecuación prenatal y nutricional fue evaluada según los criterios del Ministerio de Salud. Se construyeron dos modelos de resultados. El Resultado 1 consistió en una mínima cobertura (inicio temprano prenatal y mínimo número de visitas) y exámenes, y el Resultado 2 tuvo una mínima cobertura, exámenes y asistencia nutricional. La regresión de Poisson se usó para estimar las ratios de prevalencia. Se analizaron a 802 mujeres, e identificamos un 57% de adecuación al Resultado 1. Embarazo no planeado (RP = 0,76; IC95%: 0,68-0,86), paridad (RP = 0,88; IC95%: 0,83-0,94) y cuidado prenatal fuera de la capital del estado de Rio Grande do Sul (RP = 0,80; IC95%: 0,69-0,92) estuvieron asociados con frecuencias de educación más bajas durante el período prenatal. El Resultado 2 fue considerado adecuado para un 10,2% de las mujeres. El seguimiento realizado por parte de diferentes profesionales durante el cuidado prenatal estuvo asociado con una adecuación más baja (RP = 0,49; IC95%: 0,28-0,86). Las mujeres con embarazos de alto riesgo tuvieron una frecuencia más alta de adecuación en el Resultado 1 (RP = 1,21; IC95%: 1,07-1,37) y en el Resultado 2 (RP = 1,75; IC95%: 1,16-2,64). La adecuación general fue considerada baja en ambos resultados. Hubo una falta de asistencia nutricional durante el cuidado prenatal. Características tales como: planificación de los embarazos, paridad más baja, cuidado prenatal en la capital, seguimiento por el mismo profesional y embarazo de alto riesgo fueron predictores para la idoneidad del cuidado prenatal.

Neonatal Outcomes of Pregnancy Following Roux-en-Y Gastric Bypass: a Matched Case-Control Study.

PURPOSE: To compare perinatal outcomes and to assess the predictors of birth weight (BW) after Roux-en-Y gastric bypass (RYGB) to those women unexposed to bariatric surgery. MATERIALS AND METHODS: Singleton births from women submitted to RYGB (BSG) were matched to two control births by maternal age, delivery year, and gender. Control group 1 (CG1) and control group 2 (CG2) were selected according to the prepregnancy body mass index (BMI) < 35 kg/m2 and ≥ 35 kg/m2, respectively, without previous bariatric surgery. RESULTS: Fifty-eight pregnancies were evaluated in each group (n = 174). Neonates born after RYGB presented lower BW compared to CG1 (mean difference - 182.3 g; 95% CI - 333; - 31, P = 0.018) and CG2 (mean difference - 306.6 g, 95% CI - 502; - 111, P = 0.02). Although gestational age (GA) was similar (P = 0.219), fetal growth rate (in grams) per gestational week was higher in CG2 (ß = 196.27, P < 0.001) vs. BSG (ß = 127.65, P < 0.001), irrespective of gestational weight gain (GWG). Pregnancies post-RYGB showed lower GWG, lower BW, and higher prevalence of cesarean section than CG1 and were associated with lower BW, smaller cephalic perimeter, lower prevalence of macrosomia, hypertension, and gestational diabetes than CG2. CONCLUSION: Birth weight was higher in neonates from women with higher prepregnancy BMI, as compared to births from women submitted to RYGB, irrespective of GWG. Although nearly half of the RYGB mothers were classified with obesity at conception, those pregnancies were associated with better obstetric and neonatal outcomes than among women with prepregnancy BMI ≥ 35 kg/m2 who had never undergone RYGB.

Factors Associated With Breastfeeding Among Women With Gestational Diabetes.

BACKGROUND: Breastfeeding offers benefits to mother and child but is frequently not practiced among women whose pregnancy is complicated by gestational diabetes mellitus. Factors associated with not initiating or not maintaining breastfeeding among these women have been little investigated. RESEARCH AIMS: (1) To evaluate the frequency of breastfeeding for 30 days among women with a recent pregnancy complicated by gestational diabetes and (2) to determine factors associated with not initiating or not maintaining breastfeeding. METHODS: Between January 2014 and July 2017 we enrolled women with gestational diabetes at high-risk prenatal services in three Brazilian cities. We collected baseline sociodemographic and health data and followed up with participants by telephone. Using Kaplan-Meier curves, we calculated the proportions of participants not initiating breastfeeding or not maintaining it for at least 30 days. We used Poisson regression with robust variance to identify factors related to this outcome. RESULTS: Of the 2328 participants with complete information, 2236 (96.1%) initiated breastfeeding, and 2166 (93.1%) maintained breastfeeding for 30 days. Not having breastfed the previous infant (relative risk [RR] = 5.02, 95% CI [3.39, 7.45]), smoking during pregnancy (RR = 2.37, 95% CI [1.48, 3.80]), infant with health problems (RR = 2.25, 95% CI [1.27, 3.99]), early preterm birth (RR = 2.49, 95% CI [1.07, 5.77]), and not intending to breastfeed (RR = 3.73, 95% CI [1.89, 7.33]) were related to not maintaining breastfeeding for at least 30 days. CONCLUSIONS: Breastfeeding initiation was nearly universal among participants, and most maintained breastfeeding for 30 days. Factors relating to not breastfeeding at 30 days were easily identifiable.

Diet quality index for Brazilian adolescents: the ERICA study.

PURPOSE: This study aimed to assess the dietary patterns of adolescents using a food-based diet quality index and their compliance with a healthy dietary guideline METHODS: Participants included 71,553 Brazilian adolescents (12-17 years old) from the Study of Cardiovascular Risks in Adolescents (ERICA), a cross-sectional school-based multicenter study.. Dietary intake was measured by one 24-h recall. A second recall was collected in a random subsample (~ 10%) to correct within-person variability. The Diet Quality Index for Adolescents adapted for Brazilians (DQIA-BR) was used to measure the overall quality of the dietary intake. The National Cancer Institute method was applied to estimate usual dietary intake. The DQIA-BR and the distribution of its components (quality, diversity, and equilibrium) were analyzed according to sex, geographical area, and type of school RESULTS: The mean (SD) DQIA-BR scores were 14.8% (6.1%) for females and 19.0% (6.3%) for males. All analyzed strata revealed low scores of DQIA-BR and its components. The median usual intake was five to sevenfold below the recommendations for vegetables and fruits and approximately twofold below the recommendations for dairy. The highest DQIA-BR mean scores were found in the northern region [17.0% (6.4%), females; 20.7% (6.3%), males]. Adolescents in both types of schools had relatively similar median intakes of snacks (~ 85 g) and sugared drinks (~ 600 ml) CONCLUSIONS: The overall diet quality of Brazilian adolescents is inadequate based on evaluated parameters in all regions and socioeconomic backgrounds.

Development and Assessment of a Mobile Nutritional Counseling Tool for Primary Care Physicians.

Background:Hypertension remains widely undetected, undertreated, and poorly controlled. Appropriate dietary changes can prevent and treat hypertension effectively. Primary care physicians (PCPs) have the opportunity to counsel patients about their diets and are able to facilitate long-term adherence to changes. However, they encounter several barriers to delivery of evidence-based counseling in daily medical practice. m-Health can make important contributions.Objective:To describe the development and assessment of a Brazilian mobile app for nutritional management of hypertension supported by evidence-based.Materials and Methods:App development used a user-centered approach that seeks to solve problems in a collective and collaborative way. The app was developed in Apache Cordova® (Adobe Systems, San Jose, CA) for iOS and Android mobile phone platforms. Beta testing was performed with a sample of Brazilian PCPs (n = 62), who were asked to use the app in routine practice and evaluate it.Results:The process involved researchers, government, PCPs, nutritionists, and designers. Dieta Dash® (Universidade Federal do Rio Grande do Sul-UFRGS, Porto Alegre, Brazil) app was divided into following sections: meal evaluation, Healthy meals, Healthy choices, and a database of Healthy recipes. The mean perceived usefulness and ease-of-use scores were 23.3 and 32.3 out of 42, respectively.Conclusions:It is a great source of up-to-date and summary guidelines, usable, acceptable, and positively impact clinical care. PCPs have identified improvements that could make the user experience better. The Dieta Dash app can be incorporated into Brazilian primary care practice.

Elaboração e validação de uma medida para avaliar o conhecimento de médicos de atenção primária do Brasil sobre recomendação nutricional para controle da hipertensão / Elaboration and validation of a measure to evaluate the knowledge of primary care physicians in Brazil about nutritional recommendation for hypertension control

Resumo Introdução Médicos da Atenção Primária à Saúde têm papel primordial no aconselhamento nutricional para reduzir a morbidade e a mortalidade relacionadas à hipertensão. A literatura é escassa em instrumentos validados para o Brasil que avaliam o conhecimento com base em evidências desses profissionais. Objetivo Elaborar uma medida para avaliar o nível de conhecimento de médicos de atenção primária do Brasil sobre recomendação nutricional para o controle de hipertensão arterial. Método Utilizou-se de um instrumento validado para a língua inglesa como base para elaboração da medida, a qual foi testada de acordo com os fundamentos da Teoria de Resposta ao Item. A dimensionalidade do questionário foi realizada na matriz de correlação policórica. Para estimar os parâmetros dos itens, foi utilizado o modelo logístico de dois parâmetros (discriminação e dificuldade). Resultados A maioria dos itens foi considerada fácil, e o poder discriminativo variou entre valores altos, moderados e baixos. A ausência de itens difíceis contribuiu para a imprecisão da medida entre aqueles com níveis superiores de conhecimento. Conclusão Os resultados mostram uma medida que mensura com melhor precisão médicos com baixo nível de conhecimento, sendo uma ferramenta útil para identificar profissionais que precisam melhorar seu conhecimento nutricional.

Abstract Background Primary health care physicians play a leading role in nutritional counseling to reduce hypertension related to morbidity and mortality. The literature is scarce on instruments validated for Brazil that evaluate the evidence based on knowledge of these professionals. Objective To elaborate a measure to evaluate the level of knowledge about nutritional recommendation for the control of hypertension for primary care physicians in Brazil. Method A validated instrument for the English language was used as the basis for the questionnaire elaboration, which was tested according to the fundamentals of the Item Response Theory. The dimensionality of the questionnaire was performed on the polychoric correlation matrix. For the estimation of the parameters of the items, the two Parameters Logistic Model (discrimination and difficulty) was used. Results Most of the items were considered easy, the discriminative power varied between high, moderate and low values. The absence of difficult items contributed to the imprecision of the measure among those with higher levels of knowledge. Conclusion The results show a measure that accurately measures physicians with a low level of knowledge, being a useful tool to identify professionals who need to improve their nutritional knowledge.

Association between dietary patterns and mental disorders in pregnant women in Southern Brazil

Objective: To evaluate the association between dietary patterns and mental disorders among pregnant women in southern Brazil. Methods: Cross-sectional study with 712 pregnant women recruited from the Study of Food Intake and Eating Behaviors in Pregnancy (ECCAGe). Food intake assessment was performed using the Food Frequency Questionnaire. Dietary patterns were identified by cluster analysis. The Primary Care Evaluation of Mental Disorders (PRIME-MD) was used to evaluate participants' mental health. Poisson regression models with robust variance were fitted to estimate prevalence ratios (PR). Results: In the adjusted models, there was a high prevalence of major depressive disorder among women with low fruit intake (43%, PR 1.43, 95%CI 1.04-1.95) and high sweets and sugars intake (91%, PR 1.91, 95%CI 1.19-3.07). Women with a common-Brazilian dietary pattern had higher prevalence of major depressive disorder compared to those with a varied consumption pattern (PR 1.43, 95%CI 1.01-2.02). Low intake of beans was significantly associated with generalized anxiety disorder (PR 1.40, 95%CI 1.01-1.93). Conclusions: Low consumption of fruits and beans and intake of the common-Brazilian dietary pattern during pregnancy were associated with higher prevalence of mental disorders. These results reinforce the importance of an adequate dietary intake to ensure better mental health in pregnancy.

Agreement of dietary fiber and calorie intake values according to the choice of nutrient composition and household measure tables / Concordância dos valores de consumo de fibras alimentares e de calorias diárias de acordo com a escolha da tabela de composição de nutrientes e de medidas caseiras

ABSTRACT Objective: To analyze the variations in the daily intake of dietary fiber and calories according to the different nutrient composition and homemade measure tables. Methods: Five different methods based on different nutrient composition and household measure tables were used to calculate daily calorie and fiber intake, measured using a food frequency questionnaire, of 633 pregnant women receiving care in primary health care units in the Southern region of Brazil; they were selected to participate in a cohort study. The agreement between the five methods was evaluated using the Kappa and weighted Kappa coefficients. The Nutritional Support Table, a Brazilian traditional food composition table and the Brazilian household expenditure survey were used in Method 1. Brazilian Food Composition Table and the Table for the Assessment of Household Measures (Pinheiro) were used in Methods 2 and 3. The average values of all subtypes of food listed in the Brazilian Food Composition Table for each corresponding item in the food frequency questionnaire were calculated in the method 3. The United States Department of Agriculture Food Composition Table and the table complied by Pinheiro were used in Method 4. The Brazilian Food Composition Table and the Brazilian household expenditure survey were used in Method 5. Results: The highest agreement of calorie intake values were found between Methods 2 and 3 (Kappa=0.94; 0.92-0.95), and the lowest agreement was found between Methods 4 and 5 (Kappa=0.46; 0.42-0.50). As for the fiber intake, the highest agreement was found between Methods 2 and 5 (Kappa=0.87; 0.82-0.90), and the lowest agreement was observed between Methods 1 and 4 (Kappa=0.36; 0.3-0.43). Conclusion: Considerable differences were found between the nutritional composition tables. Therefore, the choice of the table can influence the comparability between studies.
