Background Dietary patterns can influence maternal and child health outcomes. The study aims to characterize dietary patterns during pregnancy as well as to identify their associations with gestational weight gain (GWG) and anthropometric measurements at birth. Methods A minimum sample size of 95 nursing mothers was estimated for this work. Socioeconomic, anthropometric, physical activity, obstetric and food consumption (food frequency questionnaire) data was collected from mothers and their newborns in immediate postpartum (n = 260) at the maternity hospital. Maternal pregestational weight and GWG were self-reported and the neonatal data was obtained from their records. The patterns were derived posteriori by Principal Component Analysis (PCA). Multinomial Logistic Regression and Poisson Regression with Robust Variance were applied. Findings Four dietary patterns were derived: 'pattern 1', characterized by the consumption of meat and eggs, processed meat, vegetables and olive oil; 'pattern 2', consisting of sweets, snacks and cookies; 'pattern 3', which includes cereals and breads, coffee and tea, and processed fats; and 'pattern 4', characterized by soft drinks, tubers and instant noodles. Together, the dietary patterns account for 49.16% of the total variance for food intake. Higher adherence to 'pattern 3' was associated with inadequate birth weight (low and excessive birth weight); while greater adherence to 'pattern 2' was associated with lower chances of inadequate GWG. Conclusion The dietary patterns presented mixed composition and predominance of ultra-processed foods. They were associated with the investigated outcomes, denoting the importance of strategies to promote healthy eating habits during pregnancy in order to avoid possible complications., Author(s): Larissa Bueno Ferreira [sup.1] , Cecília Viana Lobo [sup.2] , Ariene Silva do Carmo [sup.1] , Rafaela Cristina Vieira e Souza [sup.1] , Luana Caroline dos Santos [sup.3] Author [...]

It has been suggested that an imbalance in mineral levels is involved in the pathophysiology of migraine. However, only a few studies have investigated the circulating levels of mineral in patients with migraine during the pain-free period (i.e. interictal). This study aimed to investigate whether the interictal plasma levels of minerals of women with migraine differ from those of women without migraine (controls). This is a cross-sectional study involving 67 women, of which 38 were diagnosed with migraine and 29 were controls. The groups were similar in age and body mass index. Plasma levels of magnesium (Mg), copper (Cu), calcium (Ca), zinc (Zn), iron (Fe), and selenium (Se) were measured. Dietary intake was assessed using a 24-hour food recall, and migraine impact was evaluated using the Headache Impact Test, version 6 (HIT-6). The association between migraine disability, and plasma levels and dietary intake of minerals was assessed through correlation and logistic regression analyses. Women with migraine had significantly lower plasma levels of Mg, Ca, Cu, and Zn than controls. In parallel, dietary intake of Mg, Cu, and Fe was significantly lower in patients with migraine. Migraine impact was not associated with plasma levels or dietary intake of minerals. The results suggest that patients with migraine have lower plasma levels of minerals, and dietary intervention to ensure adequate mineral intake should be considered as a therapeutic strategy for migraine.

This study aimed to describe the community food environment of a Brazilian metropolis using secondary data from 2015. To construct this database, the State and Municipal Secretariat were asked to provide information on 12 types of food sales establishment in the city of Belo Horizonte. Establishments that were not common between the two databases were checked using the Google Street View database. The final database consisted of establishments that were virtually checked as well as existing establishments in the two secondary databases. The establishments included in the final database were categorized as healthy, unhealthy, or mixed according to the predominance of food sales. Unhealthy establishments are the most available in the food environment. Lower income areas have a lower availability of all types of establishment, particularly healthy ones. As income increases, there is an increase in the availability of mixed and unhealthy establishments. Understanding the food environment of cities is important for decision makers to identify places where the implementation of public equipment for food safety and nutrition is necessary.

Objective: To evaluate the association between the consumption of NOVA food groups (classification based on the nature, extent and purpose of food processing) and the intake of energy, macro and micronutrients among school children. Design: Cross-sectional study. Food consumption was assessed by two 24-h dietary recalls on non-consecutive days. Energy from each NOVA food groups – ultra-processed foods, unprocessed or minimally processed foods, processed culinary ingredients and processed foods – was estimated. For analysis, the percentage of energy from ultra-processed foods and unprocessed or minimally processed foods were categorised into tertiles and associated with intake of energy, macro and micronutrients using analysis of covariance and linear regression. Setting: Public schools in Belo Horizonte, Minas Gerais, Brazil. Participants: School children aged 8–12 years (n 797; 406 girls; 391 boys). Results: Mean energy intake was 2050·18 ± 966·83 kcal/d, 25·8 % was from ultra-processed foods, 56·7 % from unprocessed or minimally processed foods, 8·9 % from processed culinary ingredients and 8·6 % from processed foods. A higher energy contribution from ultra-processed foods was negatively associated with the intake of protein, fibre, vitamin A, Fe and Zn (P < 0·001) and positively associated with total energy, lipid and Na intake (P < 0·001). Concurrently, a higher energy contribution from unprocessed or minimally processed foods was positively associated with the consumption of protein, fibre, Fe and Zn (P < 0·001) and negatively associated with total energy (P = 0·002), lipid and Na intake (P < 0·001). Conclusions: In conclusion, higher ultra-processed food consumption presented a negative association with the nutrient intake profile of school children. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to assess the association between ultra-processed foods (UPF) consumption and some lifestyle factors during pregnancy and the baby's anthropometric measurements at birth. Methods: Cross-sectional study conducted with immediate postpartum women and their babies. Food consumption during pregnancy was assessed retrospectively by a semi-quantitative food frequency questionnaire, and the baby's anthropometric measurements were obtained from the medical records. The percentual of energy from UPF was estimated, categorized in tertiles, and associated with the baby's anthropometric measurements using multinomial logistic regression, adjusting by maternal characteristics (per capita income, maternal age, gestational weight gain, parity, physical activity, and number of prenatal consultations). Results: A total of 626 immediate postpartum women and their babies were evaluated. The mean percentual of energy from UPF consumption during pregnancy was 30.56%. Before adjustment, there was a greater chance of insufficient birth weight among babies of immediate postpartum women in the highest tertile of UPF consumption (OR 1.72; 95% CI 1.09–2.70; p = 0.020); however, such an association was not significant in the adjusted analyses. Conclusions: No association between UPF consumption during pregnancy and baby's anthropometric measurements at birth was observed, probably due to the multifactorial nature of anthropometry and the interference of sociodemographic, gestational, and environmental factors in the baby's health outcomes.

Objectives: To evaluate the direct and indirect effects of family characteristics and the perceived neighborhood environment on obesity risks among schoolchildren. Methods: Through phone contact with the child's mothers/guardians, the perceptions about the aspects of the neighborhood that could limit or promote health. Physical activity, socioeconomic data, self‐reported weight and height, and ultra‐processed consumption of the respondents were evaluated, in addition to the screen time of both mothers and children. A hybrid model of structural equations was used to test the direct and indirect effects of family and environmental variables on childhood obesity. Setting: Belo Horizonte, Minas Gerais, Brazil. Subjects: A total of 322 children from 9 to 10 years old from municipal schools and their respective mothers/guardians. Results: Childhood obesity was positively associated with obesity among mothers/guardians and with the latent variable "socioeconomic status (SES)." It was observed that the child's guardians positively influenced childhood obesity through their own habits, such as screen time and consumption of ultra‐processed products, with obesity of mothers/guardians as mediators of both associations. There were no direct and indirect effects of the latent variables of the perceived environment in childhood obesity. Conclusion: Family characteristics are important determinants of childhood obesity and should be considered when designing prevention strategies. Parental perceptions of neighborhood characteristics did not have an influence on childhood obesity. [ABSTRACT FROM AUTHOR]

Objective: To explore the impact of inadequate sleep and associated factors on the social behaviour and food consumption of children and adolescents.Design: Cross-sectional study.Setting: Sleep information, social behaviour (Strengths and Difficulties Questionnaire), food consumption, demography, nutritional status, lifestyle, and biochemical tests were investigated.Participants: School children in the 4th grade of the municipal school system of a large Brazilian city.Results: Of a total of 797 schoolchildren, 50·9 % were female, with a median age of 9·7 (9·5-10·0) years old and an energy consumption of 7613·6 (5982·7-9766·2) kJ. It was determined that 31·6 % were overweight, and 76·8 % reported insufficient weekly practice of physical activity. A median of 9·6 (8·9-10·5) h of sleep (lower values on weekdays: 9·3 v. 10·5 h, P < 0·001) was recorded. In addition, 27 % of the individuals who experienced inadequate sleep (<9 h) engaged in longer screen time daily (≥2 h/d) (P = 0·05), had an inadequate bedtime (> 22 h) or adequate wake-up time (5-7 h), studied in the morning (P < 0·001) and never took a shower before school (P < 0·001). Of the entire sample, 9·9 % had poor or very poor sleep quality and a greater probability of sleep talking regularly, had difficulty falling asleep, and engaged in inadequate social behaviour while experiencing these conditions compared with those with positive sleep quality. There was no association between sleep and the other variables investigated.Conclusions: Sleep impairment contributed to changes in sleep and social behaviour in schoolchildren. The findings of this study may reinforce the importance of developing actions to promote adequate sleep and a healthy lifestyle at school age. [ABSTRACT FROM AUTHOR]

Objectives: to perform a systematic review of studies that investigated the influence of ultra-processed foods (UPF) consumption during pregnancy on child’s anthropometric parameters up to one year of life. Methods: cohort and cross-sectional studies were researched in BVS, Cinahl, Cochrane, Embase, Pubmed, Scopus and Web of Science databases until March 2020, and the main descriptors were: “Pregnant Women”, “Ultra-processed foods”, “Birth Weight”, “Small for Gestational Age”, “Infant”, “Newborn”. Results: seventeen articles were considered eligible and evaluated the associations between the exposures: ultra-processed dietary patterns; soft drinks, sugar-sweetened beverages, artificially sweetened beverages; fast food, junk food, sweets, snacks and the outcomes: birth weight and its classifications; length and head circumference at birth; birth weight adjustments according to gestational age; weight/age, length/age, body mass index/age and weight/length indices. The results showed: 36 non-significant associations between the exposures and the outcomes; 13 direct associations (outcomes versus ultraprocessed dietary patterns, soft drinks, artificially sweetened beverages, sweets, junk food) and 5 inverse associations (outcomes versus ultra-processed dietary patterns, soft drinks). Conclusions: most of the evaluated literature did not demonstrate the influence of UPF consumption during pregnancy on the newborn’s anthropometric measurements up to one year of life and denoted a smaller number of direct and inverse associations between the exposures and the outcomes.
