Symphysis fundal height charts: Results from the Brazilian Maternal and Child Nutrition Consortium Thais Rangel Bousquet Carrilho, Michael E. Reichenheim, José Guilherme Cecatti, Renato T. Souza, Marco F. Mastroeni, et al. International Journal of Gynecology and Obstetrics, 2026 ObjectivesTo construct prescriptive symphysis fundal height (SFH) curves based on data from the Brazilian Maternal and Child Nutrition Consortium (BMCNC).MethodsIndividual patient data from seven cohorts from the BMCNC were used. Adult women with singleton pregnancies, free of infectious and chronic diseases, gestational diabetes, and hypertensive disorders, who did not smoke or consume alcohol during pregnancy and delivered a live birth at term, adequate for gestational age, and with birth weight between 2500 and 4000 g were selected. SFH was obtained from medical records. The data were harmonized and cleaned and then split into training (n = 3969 individuals; 21 760 SFH measurements) and validation (n = 1700 individuals; 9284 SFH measurements). Fractional polynomial models were used to construct SFH curves between 14 and 40 gestational weeks.ResultsThe predicted median for SFH at 40 weeks was 36.1 cm (interquartile range, 34.5–37.7 cm). The internal and cross‐validation results showed that the percentages of SFH measurements below the selected percentiles were close to those expected.ConclusionThe new SFH charts will allow healthcare professionals to monitor SFH and identify individuals at risk for delivering neonates with adverse outcomes, improving the prenatal care routine in Brazil.
Iodine Deficiency and Excess in Brazilian Pregnant Women: A Multicenter Cross-Sectional Study (EMDI-Brazil) Aline Carare Candido, Francilene Maria Azevedo, Sarah Aparecida Vieira Ribeiro, Anderson Marliere Navarro, Mariana de Souza Macedo, et al. Nutrients, 2025 Background/Objectives: Iodine is an important nutrient for the human body, used in the production of thyroid hormones. During pregnancy, a deficiency can cause miscarriage and hypothyroidism, while an excess can cause thyroid dysfunction. Therefore, the objective of this study was to evaluate the factors associated with the iodine nutritional status of pregnant Brazilian women. Methods: This was a cross-sectional, multicenter study conducted with pregnant women over 18 years of age, users of the Unified Health System (SUS). A semi-structured questionnaire was used to obtain sociodemographic information. Iodine status was assessed by urinary iodine concentration (UIC). The iodine content of salt and homemade and industrial seasonings was determined by the titrimetric method. Dietary intake was estimated through a 24-hour dietary recall. The chi-square test and hierarchical multinomial logistic regression were used for statistical analysis. The significance level was set at p ≤ 0.05. Results: Among Brazilian pregnant women, the median UIC was 186.7 µg/L (P25: 118.05 µg/L-P75: 280.93 µg/L). Regarding iodine nutritional status, the prevalence of deficiency was 36.7% (n = 694), above the requirement was 28.7% (n = 543), and excess iodine intake was 3.6% (n = 68). We observed that non-white pregnant women were more likely (OR = 1.83; 95% CI: 1.27–2.64) to have iodine deficiency, and those who did not work were less likely (OR = 0.71; 95% CI: 0.52–0.98). Pregnant women in the last trimester of pregnancy were less likely to have iodine intake above the requirements (OR = 0.52; 95% CI: 0.31–0.88). Conclusions: A substantial proportion of pregnant women had iodine deficiency or intake above the required level. Iodine deficiency is more chance among non-white pregnant women and less chance among those not employed during pregnancy. On the other hand, pregnant women who were in their third trimester of pregnancy were less likely to have iodine intake above the required level.
Consumption of Ultraprocessed Foods Among Brazilian Pregnant Women Attended in Primary Healthcare Gabriele B. Silva, Débora L. F. Silva, Sylvia C. C. Franceschini, Mariana S. Macedo, Claudia C. B. Almeida, et al. Journal of Nutrition and Metabolism, 2025 The objective of the study was to describe the dietary intake of Brazilian pregnant women assisted by primary healthcare, focusing on the degree of food processing. Data from the cross‐sectional multicenter study of iodine deficiency were analyzed. Participants were selected from basic health units in 11 research centers and completed questionnaires regarding socioeconomic status, demographics, and health. Dietary intake information was collected through 24 h recall and analyzed using GloboDiet software. Descriptive analyses estimated the average energy contribution and confidence interval (%) of NOVA food groups in total energy intake, considering the research center, sociodemographic factors, health status, and pregnancy characteristics. The analysis included 2247 pregnant women without history of thyroid disease or surgery, hypothyroidism, or hypertension. Unprocessed or minimally processed foods accounted for 62.1% of total energy intake, while ultraprocessed foods accounted for 23.8%. Food consumption predominantly occurred at home across all NOVA food groups. Ultraprocessed food consumption was lower during lunch and dinner but higher after dinner and when consumed outside the home, particularly in street settings, markets, parks, and/or beaches, compared with other food groups. This pattern was more prevalent among younger pregnant women (p < 0.001), those of white or yellow race (p = 0.007), residing in urban areas (p = 0.03), and with higher monthly household income (p = 0.001). These findings indicate a significant impact on the overall nutritional quality of the diet among pregnant women, with variations based on factors such as age, place of residence, race, income, place of consumption, and occasion of consumption.
Factors associated with the dietary total antioxidant capacity of pregnant Brazilian women Roberta Rejane Santos de Carvalho, Poliana Cristina de Almeida Fonseca Viola, Sandra Patrícia Crispim, Ana Karina Teixeira da Cunha França, Anderson Marliere Navarro, et al. Revista Brasileira De Epidemiologia, 2025 Objective: To investigate the sociodemographic, maternal, and gestational factors associated with the dietary total antioxidant capacity in pregnant Brazilian women. Methods: A cross-sectional study with 2,232 pregnant women aged 18 years old or older, in the first, second, and third trimesters of pregnancy, from eleven cities in the five Brazilian regions. A semi-structured questionnaire was applied to assess socioeconomic, demographic, and health data, and a 24-hour dietary recall (R24h) was used to assess food consumption and analyze the dietary total antioxidant capacity (DTAC), estimated using the ferric reducing antioxidant power (FRAP) method. Results: The median of DTAC was 5.32 mmol/day. Aracaju, Sergipe (SE) had the highest median of DTAC (6.44 mmol/day) and Palmas, Tocantins (TO) had the lowest (4.71 mmol/day). Pregnant women aged 20 to 34 years (OR 1.86; 95%CI 1.26-2.76), 35 years old or older (OR 3.68; 95%CI 2.21-6.14) and who were in the second trimester of pregnancy (OR 1.50; 95%CI 1.11-2.01) were more likely to be above the median DTAC. While pregnant women with higher education had a 67% lower chance of being above the median DTAC (OR 0.67; 95%CI 0.48-0.92). Conclusion: The study demonstrated that there are differences in antioxidant consumption in different cities in Brazil and that associated factors such as age, education, and gestational trimester can impact the intake of foods rich in antioxidants. The profile found draws attention to the importance of an adequate diet rich in antioxidants during prenatal care.
Association between breast feeding and food consumption according to the degree of processing in Brazil: a cohort study Carolina Abreu de Carvalho, Poliana Cristina de Almeida Fonseca Viola, Elma Izze da Silva Magalhães, Soraia Pinheiro Machado, Alicia Matijasevich, et al. BMJ Open, 2024 BackgroundThe benefits of breast feeding may be associated with better formation of eating habits beyond childhood. This study was designed to verify the association between breast feeding and food consumption according to the degree of processing in four Brazilian birth cohorts.MethodsThe duration of exclusive, predominant and total breast feeding was evaluated. The analysis of the energy contribution of fresh or minimally processed foods (FMPF) and ultra-processed foods (UPF) in the diet was evaluated during childhood (13–36 months), adolescence (11–18 years) and adulthood (22, 23 and 30 years).ResultsThose who were predominantly breastfed for less than 4 months had a higher UPF consumption (β 3.14, 95% CI 0.82 to 5.47) and a lower FMPF consumption (β −3.47, 95% CI −5.91 to −1.02) at age 22 years in the 1993 cohort. Exclusive breast feeding (EBF) for less than 6 months was associated with increased UPF consumption (β 1.75, 95% CI 0.25 to 3.24) and reduced FMPF consumption (β −1.49, 95% CI −2.93 to −0.04) at age 11 years in the 2004 cohort. In this same cohort, total breast feeding for less than 12 months was associated with increased UPF consumption (β 1.12, 95% CI 0.24 to 2.19) and decreased FMPF consumption (β −1.13, 95% CI −2 .07 to −0.19). Children who did not receive EBF for 6 months showed an increase in the energy contribution of UPF (β 2.36, 95% CI 0.53 to 4.18) and a decrease in FMPF (β −2.33, 95% CI −4 .19 to −0.48) in the diet at 13–36 months in the 2010 cohort. In this cohort, children who were breastfed for less than 12 months in total had higher UPF consumption (β 2.16, 95% CI 0.81 to 3.51) and lower FMPF consumption (β −1.79, 95% CI −3.09 to −0.48).ConclusionExposure to breast feeding is associated with lower UPF consumption and higher FMPF consumption in childhood, adolescence and adulthood.
Dietary inflammatory index and inflammatory markers in Brazilian adolescents Renata de Sousa Gomes, Poliana Cristina de Almeida Fonseca Viola, Roberta Rejane Santos de Carvalho, Nitin Shivappa, James R. Hebert, et al. Revista De Saude Publica, 2024 OBJECTIVE: To evaluate the association between t he inflammatory potential of the diet measured by the energy-adjusted diet inflammatory index (E-DII) and inflammatory markers in adolescents. METHODS: This cross-sectional study was conducted among 518 adolescents aged 18 and 19 years from São Luís, Maranhão, Brazil in 2016. A semiquantitative food frequency questionnaire (FFQ) was used to assess dietary intake from which E-DII scores were calculated to determine the inflammatory potential of the diet. The associations between E-DII and inflammatory markers (hs-CRP, IL-6, IL-4, TNF-α, and IFNγ) were analyzed using multivariable linear regression. The variables included in the adjusted model were identified using the directed acyclic graph. RESULTS: The diet of these adolescents was mostly pro-inflammatory; mean E-DII score was 1.71 and ranged from -2.44 to 5.58. Higher E-DII scores were positively associated with higher levels of IFNγ in the adjusted analysis (Adjusted Coef.: 1.19; 95%CI: 0.36–12.04). We observed no associations between E-DII and other inflammatory markers (hs-CRP, IL-6, IL-4, TNF-α). Study results indicate that E-DII is useful in evaluating the inflammatory potential of the diet of Brazilian adolescents. CONCLUSIONS: Cross-sectionally E-DII scores were positively associated with IFNγ concentrations. Future research should examine the association between changes in E-DII scores and levels of inflammatory markers longitudinally.
Unhealthy Dietary Pattern Associated with Common Mental Disorders in Adults and Older Adults: A Population-based Study Ana Paula de Melo Simplício, Poliana Cristina de Almeida Fonseca Viola, Layanne Cristina de Carvalho Lavôr, Paulo Víctor de Lima Sousa, Carolina Abreu de Carvalho, et al. Current Nutrition and Food Science, 2024 Background:: Mental and behavioral disorders are influenced by biological, psychological and social factors, especially income, gender, age and family environment, indicating that physical health is directly associated with mental health. In this perspective, food consumption is highlighted as a risk factor for mental health, as healthy behaviors, along with a good quality diet, can reduce symptoms of anxiety and depression. Objective:: The objective of this a study is to investigate the association between CMD and dietary patterns, among other lifestyle and socioeconomic factors. Method:: Cross-sectional population-based and household study conducted with 1574 individuals aged over 20 years, of both sexes, residing in Teresina and Picos, Piaui, Brazil. Sociodemographic, lifestyle and food consumption data were collected. The instrument used to identify the presence of CMDs was the Self Reporting Questionnaire 20 (SRQ-20). Dietary patterns were obtained using the Principal Component Analysis method. Results:: Individuals of female sex, separated, with low education, smokers and lower level of physical activity had a higher prevalence of common mental disorders. As for the eating pattern, after adjustments, individuals who adhered to the unhealthy eating pattern had a 9% higher prevalence of CMD. Furthermore, adherence to the white meat standard represented 12% higher prevalence of CMD. Conclusion:: The results showed that, regardless of other socioeconomic and lifestyle factors, adherence to a more monotonous eating pattern in foods, characterized by the mainly consumption of animal protein and the lack consumption of foods like fruits and vegetables, as well as a less healthy one, characterized by the consumption of ultra-processed foods, increases the risk of developing CMD.
