Effect of antenatal omega-3 supplementation on maternal depressive symptoms from pregnancy to 6 months postpartum: a randomized double-blind placebo-controlled trial.

OBJECTIVE: Randomized double-blind placebo-controlled trial was conducted with sixty pregnant women to evaluate the effect of antenatal omega-3 supplementation on maternal depressive symptoms from pregnancy to 6 months postpartum. METHODS: Participants with gestational age between 22 and 24 weeks were randomized in placebo (olive oil; n = 30) or omega-3 (fish oil; n = 30) groups and supplemented until childbirth. Fish oil capsules provided 1440 mg/day of docosahexaenoic acid. Depressive symptoms were evaluated during the gestational period: (G1) 22-24 weeks; (G2) 26-28 weeks; (G3) 30-32 weeks; (G4) 34-36 weeks; and postpartum: (P1) second week; (P2) first month; (P3) fourth month; and (P4) sixth month, using the Edinburgh Postnatal Depression Scale (EPDS). Intention-to-treat and per-protocol analyses were performed using Generalized Estimating Equations (GEE). RESULTS: Comparison between groups showed no differences in the EPDS score at any time during pregnancy or postpartum, in both intention-to-treat and per-protocol analysis (p > 0.05). Both groups presented a reduction in the EPDS score over time. According to intention-to-treat analysis, when comparing to the baseline, the placebo group showed a reduction in the EPDS score at P1 and P4, while the omega-3 group showed a reduction at all times from G4 to P4. In per-protocol analysis, the placebo group showed a reduction in the EPDS score at P3, while the omega-3 group showed a reduction at all times from G2 to P4. CONCLUSIONS: The supplementation with omega-3 did not promote significant differences between groups. However, an earlier reduction in the EPDS score was observed in the omega-3 group, which may indicate a benefit of antenatal omega-3 supplementation.

Dietary fatty acids, omega-6/omega-3 ratio and cholesterol intake associated with depressive symptoms in low-risk pregnancy.

ABSTRACTObjective: This cross-sectional study aimed to evaluate the association of dietary fatty acids, cholesterol and omega-6/omega-3 ratio to depressive symptoms in a sample of low-risk pregnant women.Methods: Pregnant women (n = 60) within 20-40 years of age and with 22-24 gestational weeks were evaluated. Food intake was assessed by two 24-h recalls and depressive symptoms according to the Edinburgh Postnatal Depression Scale.Results: The prevalence of depressive symptoms was 18.3%. The Prevalence Ratio (PR) adjusted by per capita income, history of depression and pregnancy intention, showed a higher prevalence of depressive symptoms among pregnant women with excessive total fatty acid intake (PR: 5.80; CI95% 1.20-27.7) and omega-6/omega-3 ratio above 10:1 (PR: 3.63; CI95% 1.20-10.94).Discussion: Our results indicated a higher risk of depressive symptoms among pregnant women with total fatty acids intake and omega-6/omega-3 ratio above recommendation, but further studies are required to elucidate the mechanism of dietary fatty acids in the onset of maternal depression.

Consuming school meals improves Brazilian children's diets according to their social vulnerability risk.

OBJECTIVE: To estimate usual diets among Brazilian children regarding the consumption of school meals and social vulnerability risks. DESIGN: A cross-sectional study. School meal consumers were considered those children who reported consuming school meals ≥3 times/week. Social vulnerability risk was classified by an index. Dietary intake was evaluated by one 24 h dietary recall for the whole sample; a second 24 h dietary recall was administered in a sub-sample (38·6 %). The National Cancer Institute's method was used to estimate children's usual intake of nutrients and food groups. SETTING: Municipal public schools from Belo Horizonte, Brazil. PARTICIPANTS: Children (n 1357) aged 8-12 years. RESULTS: Half of the sample lived in low/medium social vulnerability risk areas and 27·9 % were school meal non-consumers. School meal consumers more frequently lived in high/very high social vulnerability risk areas (76·2 v. 68·7 %). Children with low/medium social vulnerability risk had a higher mean intake of thiamin (1·13 v. 1·04 mg) and a lower mean intake of candy (1·35 v. 1·42 g). Consumption of school meals among children under high/very high social vulnerability risk was associated with higher mean consumption of vitamin C (31·9 v. 24·1 mg), unprocessed/minimally processed foods (956·3 v. 851·9 g), fruits (128·5 v. 90·9 g) and vegetables (58·2 v. 47·1 g). Ultra-processed food product consumption was lower among school meal consumers (136·2 v. 187·7 g), especially ultra-processed beverages (252·5 v. 305·7 g). CONCLUSIONS: Consuming school meals was associated with a better usual diet quality, particularly among those with higher social vulnerability risk.

Factors Associated with the Consumption of Food Markers of Unhealthy Diet Among School Children in Situations of High Health Vulnerability.

Cross-sectional study that aimed to investigate the factors associated with the consumption of food markers of unhealthy diet among school children with high health vulnerability in public schools of a Brazilian capital. Unhealthy food consumption was investigated through a simplified Food Frequency Questionnaire. Multivariate logistic regression was performed, considering excessive consumption of unhealthy foods as an outcome. A total of 299 students were evaluated, with a mean age of 11.0 ± 2.4 years, 54.8% female and 20.2% overweight. Excessive consumption of unhealthy foods was observed in 46.2% of the sampled population. The chance of excessive consumption of unhealthy foods was greater among school children who skip breakfast (OR = 2.80; 95% CI 1.38-6.48); and those who habitually eat in front of the screen (OR = 2.99; 95% CI 1.11-7.06). These findings can guide interventions to promote healthy habits among school children with high health vulnerability, preventing lifelong excess weight.

Factors Associated with Nipple Lesions in Puerperae.

This retrospective cross-sectional study aimed to evaluate the factors associated with nipple lesion development in puerperae. Analyses were performed using the Poisson regression with robust variance. The level of significance was set at 5% (p < 0.05). We evaluated 1270 puerperae, among whom 193 (15.4%) presented with nipple lesions. The condition was more prevalent among the mothers who did not receive information about breastfeeding [PR, 1.69; 95% confidence interval (CI), 1.19-2.42], those who underwent cesarean delivery (PR, 1.48; 95% CI, 1.02-2.16), those who used a pacifier (prevalence ratios (PR), 2.04; 95% CI, 1.05-3.95), those who used baby formula only (PR, 1.61; 95% CI, 4.82-5.36) and those who used baby formula combined with breastfeeding (PR, 1.61; 95% CI, 1.06-2.45). A lower incidence of nipple lesions was observed among those who did not receive information on hand expression of breast milk (PR, 0.65; 95% CI, 0.46-0.93) and those who did not breastfeed in the first hour of life (PR, 0.61; 95% CI, 0.38-0.97).

[Contribution of extended school hours to the nutritional and physical activity profile of schoolchildren]. / Contribuição do turno escolar estendido para o perfil alimentar e de atividade física entre escolares.

OBJECTIVE: To evaluate the influence of the amount of time spent in school on food intake, nutritional status, and physical activity profile. METHODS: In this cross-sectional study, student data from two programs were compared in a city school in Belo Horizonte: integrated school (EI), in which students spend longer hours in school, and traditional school (ET), where students stay in school one shift only. First to 6th year students were studied in the first half of 2010. Demographic, socioeconomic, and physical data, as well as anthropometric activity and food intake were assessed. RESULTS: Two hundred and ninety-four students participated in the study, 53.0% from the EI program. Overweight was observed in 14.5% and 17.6% of EI and ET students, respectively (P = 0.781). A higher median frequency of physical activity was identified in EI (4.5 [2.0-7.0] hours/week vs. 2.0 [2.0-5.2] in ET; P = 0.004). EI students also had more adequate intake of carbohydrates (82.9% vs. 76.1% in ET; P = 0.01) and fruit (81.8% vs. 18.2% in ET; P = 0.004), and more adequate number of daily meals (67.6% vs. 32.4% in ET; P = 0.002). CONCLUSIONS: Longer hours school provided better dietary parameters and favored physical activity among students. Such findings may be useful to foster change in anthropometric parameters to be investigated in the long term.

Does antenatal supplementation with omega-3 affect child development and behavior during the first six months of life? A randomized double-blind placebo-controlled trial.

BACKGROUND: Omega-3 fatty acids, especially docosahexaenoic acid (DHA), are found in different cell membranes, but more concentrated in the brain, playing an important role in child's behavior and development. AIMS: To evaluate the effect of antenatal omega-3 supplementation on child development and behavior during the first six months of life. STUDY DESIGN: Randomized double-blind placebo-controlled trial. SUBJECTS: Low-risk pregnant women with gestational age between 22 and 24 weeks were randomized in placebo (olive oil; n = 30) or omega-3 (fish oil; 1440 mg/day of DHA; n = 30) groups and supplemented until childbirth. OUTCOME MEASURES: Child development was assessed using the Survey of Well-being of Young Children in the first, fourth and sixth month of life. RESULTS: The comparison between groups showed no differences in the Developmental Milestones score at any time, but when compared to the first month, the omega-3 group showed an increase at the fourth and sixth month. Such increase was not observed in the placebo group. No differences were found between groups for Irritability and Inflexibility scores, however, higher scores for Difficulty with Routine were observed in the placebo group when compared to omega-3 at first, fourth and sixth month. CONCLUSION: There were no differences between groups for child development, but the omega-3 group showed an increase in this score over time. The placebo group had greater difficulty with routine than the omega-3 group, indicating a beneficial effect of antenatal supplementation on child behavior. TRIAL REGISTRATION: ReBec U1111-1215-7952 (June 16th 2018).

The influence of neighborhood safety and built environment on childhood obesity: isolated and combined effect of contextual factors.

This study aims to analyze the isolated and combined effect of objective measures concerning neighborhood safety, food, and physical activity environments on students' obesity. This is a cross-sectional study conducted with 9- and 10-year-old children enrolled in the municipal education network of a Brazilian metropolis. Environment objective measures comprised neighborhood unsafety (annual criminality and road traffic accident rates), availability of public parks and spaces for physical activity practicing, and index of establishments that predominantly sell ultra-processed food. Euclidean buffers of 1,000m around the children's house were used as eligible geographic units. This study adopted the Principal Component Analysis and Generalized Estimation Equation models. Stratified analyses were conducted based on neighborhood unsafety and on child's family income. In total, 717 students were assessed, 12.2% of them were children with obesity. The latent variable of the obesogenic environment (deduced by environment unsafety rates and the index of establishments that predominantly sell ultra-processed food) was a risk factor for obesity in children with lower socioeconomic levels (OR = 2.37; 95%CI: 1.06-5.19). Public parks and spaces for physical activity practicing were protective factors against childhood obesity only in locations recording the lowest environment unsafety rates (OR = 0.30; 95%CI: 0.09-0.94). Based on our findings, social conditions change the effect of the environment on childhood obesity, reinforcing the relevance of inter-sectoral policies and strategies against this condition.

Evaluation of Nutrient Consumption for the Prevention of Chronic Diseases in Health Promotion Services: A Controlled and Randomized Community Trial to Promote Fruits and Vegetables.

To evaluate the effectiveness of a collective intervention to encourage the consumption of fruits and vegetables on the nutrients intake for the prevention of chronic non-communicable diseases (NCDs), a randomized controlled community trial was conducted with a representative sample from the Health Academy Program. While the individuals in the control group (CG) participated in regular physical exercise, those in the intervention group (IG) also participated in a collective intervention. After 12 months, IG and CG showed a reduction in energy, omega 3 and sodium intake and an increase in the consumption of carbohydrates, fiber, vitamins, and minerals. Individuals from the CG showed an increase in phosphorus consumption and, in the IG, a reduction in the consumption of total, saturated, and polyunsaturated fats as well as an increase in the consumption of monounsaturated fats was seen. In both groups, there was an increase in the prevalence of adequate nutrients. Participation in the nutritional intervention was associated with lower consumption of energy and protein in the diet. The results pointed to the importance of individuals' participation in the program, which, associated with nutritional intervention, promoted an improvement in the nutrient profile of the diet and the prevention and control of NCDs.

Dietary Patterns during Pregnancy and Gestational Weight Gain: A Systematic Review.

The present systematic review (PROSPERO: CRD42020148630) hypothesizes the association of excessive weight gain during pregnancy with dietary patterns composed of ultraprocessed foods. Thus, the objective was to investigate the association between dietary patterns after analysis and weight gain during pregnancy. The search for articles was performed in nine databases. Two reviewers selected the articles in the databases and extracted from them the data used in the review. Two scales were used to evaluate the quality of the selected studies: New Castle-Ottawa Quality Assessment for cohort-based studies and Appraisal tool for Cross-Sectional Studies (AXIS) for cross-sectional-based studies. In total, 11 studies were identified with sample size variation (n = 173-5,733). Women presenting more adherence to healthy and traditional patterns (fruits, vegetables, salads, nuts, and dairy) recorded less excessive gestational weight gain (GWG). Higher intake of mixed patterns and western patterns rich in ultraprocessed foods were associated with a higher prevalence of excessive GWG (24.48-55.20%). Gestational dietary patterns a posteriori-derived that have presented ultraprocessed components rich in fat and sugars presented association with high GWG; healthy and traditional dietary patterns were related to better mother-child health conditions, such as adequate GWG.

A presente revisão sistemática (PROSPERO: CRD42020148630) tem como hipótese que o ganho de peso excessivo durante a gravidez está associado aos padrões alimentares compostos por alimentos ultraprocessados. Desta forma, objetivou-se investigar a associação entre o padrão alimentar a posteriori e o ganho de peso durante a gestação. A busca de artigos foi realizada em nove bases de dados. Dois revisores selecionaram os artigos nestas bases e extraíram as informações utilizadas na revisão. Duas escalas foram utilizadas para avaliar a qualidade dos estudos selecionados: Escala de Avaliação da Qualidade de New Castle-Ottawa para estudos baseados em coortes e a Ferramenta de Avaliação de Estudos Transversais (escala AXIS) para estudos transversais. No total, foram identificados 11 trabalhos com variação do tamanho amostral (n = 173­5.733). As mulheres que apresentaram maior adesão aos padrões alimentares saudáveis e tradicionais (frutas, hortaliças e vegetais, nozes e laticínios) apresentaram menor ganho de peso gestacional (GPG). A maior ingestão de padrões alimentares mistos e ocidentais ricos em alimentos ultraprocessados foi associada a uma maior prevalência de GPG excessivo (24,48­55,20%). Os padrões alimentares gestacionais derivados a posteriori que apresentaram componentes ultraprocessados ricos em gordura e açúcares apresentaram associação com o maior GPG; os padrões alimentares saudáveis e tradicionais foram relacionados a melhores condições de saúde materno-infantil, como GPG adequado.

PARTICIPATION OF ULTRA-PROCESSED FOODS IN BRAZILIAN SCHOOL CHILDREN'S DIET AND ASSOCIATED FACTORS.

OBJECTIVE: To evaluate the contribution of ultra-processed foods (UPF) in the schoolchildren diet and associated factors. METHODS: Cross-sectional study with children from public schools in Southeast of Brazil, aged eight to 12 years old. A questionnaire was applied to the students to investigate anthropometric data, eating and lifestyle habits and food consumption. The consumption of UPF was evaluated by two 24-hour dietary recalls (24HR) of non-consecutive days, and the NOVA method was adopted for food classification. The sample was estimated considering the percentage of total caloric value from UPF identified by a similar study (n=260). The association between variables was evaluated by Simple and Multiple Logistic Regression. RESULTS: The average energy consumption was 1992 kcal/day, 25.2% from UPF. Schoolchildren had a mean of 9.8±0.5 years of age, 53.4% were female and 32.6% were overweight. The most consumed UPF were industrialized pastas, sweet biscuits, sausages, chocolate powder and soft drinks. In the multivariate model, schoolchildren who have the habit of TV watching during meals and those with obesity presented 1.87 (95% confidence interval [95%CI] 1.03-3.39) and 2.05 (95%CI 1,01-4.20) times more chance of having higher consumption of ultra-processed foods, respectively. CONCLUSIONS: The contribution of UPF was expressive in the feeding of the students and it was positively associated with the excess of weight and with the habit of eating while watching television. These findings indicate the importance of nutritional interventions to promote healthy habits, thus preventing overweight during childhood.

The habit of buying foods announced on television increases ultra-processed products intake among schoolchildren.

This study aimed to verify the effects of buying television advertised food in schoolchildren eating behaviors. We performed a cross-sectional study with fourth grade students of an elementary education in Belo Horizonte, Minas Gerais State, Brazil. We analyzed anthropometric data, the habit of buying television advertised food/beverages, and food consumption (two 24-hour dietary recalls). Logistic regression models were conducted and adjusted for gender, age, caloric intake, nutritional status, and social deprivation of area of residence. In total, 797 children were evaluated, the mean age was 9.81 (0.59) years, 50.7% were female, and 32.4% overweight. The prevalence of the habit of buying television advertised food was 43.1%, among which 99.3% concerned ultra-processed foods, according to the classification proposed by Monteiro et al. (2016), mainly milk beverages (12.1%), industrialized biscuits (11.5%) and candies (9.5%). The habit of buying advertised food increased the chance of consuming ultra-processed foods (OR = 1.92; 95%CI: 1.06-3.46). We found no correlation between this habit and the consumption of minimally processed and processed foods (p < 0.05). This study findings may corroborate the debate on food advertising policy and the development of effective nutrition interventions among schoolchildren, which should involve integrated education bringing together children and parents.

Usual diet quality among 8- to 12-year-old Brazilian children.

Nutritional surveys are important information sources for public policy in the food and nutrition field. They focus on assessing usual dietary patterns, because health outcomes result from the long-term intake. Here we aimed to evaluate diet quality adjusted for day-to-day variance among Brazilian children. Data were collected between March 2013 and August 2015. The sample included 8- to 12-year-old children (n = 1,357) from public schools from all administrative regions of a Brazilian city. One 24-h dietary recall (24HR) was collected for the whole sample and two 24HR for two non-consecutive days of the same week for a subsample. The Healthy Eating Index-2010 (HEI-2010) was adapted to Brazilian food habits and the Brazilian dietary guidelines were used to evaluate diet quality. Statistical analysis included a multipart, nonlinear mixed model with correlated random effects proposed by the U.S. National Cancer Institute to correct diet quality for day-to-day variance. The adapted HEI-2010 total score was 51.8. Children with poorer diet quality (< 10th percentile) scored less than 41.1, and children with higher diet quality (> 90th percentile) scored more than 62.4. The overall adequacy of adapted HEI-2010 components was low. Higher adequacy percentages were identified for total protein foods (94.9%), greens (62.3%), and seafood and plant proteins (52.2%). Seven components showed less than 10% of adequacy: refined grains, fatty acids, dairy, sodium, total vegetable, whole grains, and empty calories. This study identified the main inadequacies among children's diet quality, which can guide promotion actions for healthy eating.

Nutritional intervention may improve migraine severity: a pilot study.

OBJECTIVE: Although some studies have investigated the role of nutritional intervention on migraine, they had focused on triggers or on weight change and, to the best of our knowledge, none studied diet quality. OBJECTIVE: To investigate whether nutritional intervention focused on improving diet quality and healthy weight can promote improvement in clinical parameters of women with migraine. METHODS: Non-controlled and non-randomized intervention study conducted for 90 days. Women received an individualized diet meal plan and nutritional orientation according to their nutritional diagnosis. Anthropometric, clinical and nutritional data were measured once a month. Diet energy content and macronutrients were evaluated using 24-hour dietary recall. Diet quality was assessed through the Brazilian Healthy Eating Index-Revised (BHEI-R). The Migraine Disability Assessment and Headache Impact Test version 6 were used to assess the severity of migraine, and the Beck Depression Inventory evaluated depressive symptoms. RESULTS: Fifty-two women aged 44.0 ± 13.0 years were enrolled. Anthropometric characteristics, energy, macronutrients and fiber intake did not change after intervention. However, the BHEI-R scores improved after 60 and 90 days of intervention. Concurrent to this, the Beck Depression Inventory scores and Headache Impact Test scores decreased after 60 and 90 days, respectively. The change in the BHEI-R score was negatively correlated with the migraine severity as assessed by the Headache Impact Test at the end of the intervention. CONCLUSIONS: We concluded that the management of diet quality may be a good strategy for improving migraine severity, regardless of the nutritional status and weight change.

Body trunk fat and insulin resistance in post-pubertal obese adolescents.

CONTEXT AND OBJECTIVE: Insulin resistance is a metabolic disorder commonly associated with excess body fat accumulation that may increase chronic disease risk. The present study was undertaken to evaluate the relationship between body composition and insulin resistance among obese adolescents. DESIGN AND SETTING: Cross-sectional study, at the Adolescence Center, Pediatric Department, Universidade Federal de São Paulo. METHODS: Body composition was assessed using dual-energy X-ray absorptiometry. Dietary intake was evaluated using a three-day dietary record. The biochemical evaluation comprised glucose, insulin, serum lipid, leptin and ghrelin measurements. Insulin resistance was calculated by means of the homeostasis model assessment of insulin resistance (HOMA-IR). RESULTS: Forty-nine post-pubertal obese adolescents participated in the study: 12 boys and 37 girls of mean age 16.6 (1.4) years and mean body mass index (BMI) of 35.0 (3.9) kg/m(2). The mean glucose, insulin and HOMA values were 90.3 (6.4) mg/dl, 16.6 (8.1) microIU/ml and 3.7 (1.9), respectively. Hyperinsulinemia and insulin resistance were observed in 40.2% and 57.1% of the subjects, respectively. Adolescents with insulin resistance had higher BMI and body trunk fat. There was a trend towards higher leptin concentration in obese individuals with insulin resistance. Insulin resistance was positively correlated with body trunk fat, BMI, body fat mass (kg), leptin and body fat percentage. Furthermore, there was a negative correlation between HOMA-IR and lean body mass. The body composition predicted 30% of the HOMA-IR levels, according to linear regression models. CONCLUSION: Body trunk fat was significantly associated with insulin resistance, demonstrating the clinical importance of abdominal obesity during adolescence.

A systematic review of nutritional and sociodemographic characteristics of nursing mothers, using the published literature from 2004 to 2014 in the Biblioteca Virtual de Saúde and Medline databases. Using the following key words, 561 articles were identified: "Human Milk" and "Milk Banks"; keywords: "Profile," "Nutritional," "Milk Donor," "Nursing Mother" and "Nursing Mothers"; available abstracts; date and language. From these, 84.1% were excluded for not dealing with the established subject, 1.8% for being a review and 7.5% for the unavailability of abstracts for study. Thirty-seven articles were selected, of which 18.9% analyzed the profile of the HM donor. Of the total, 89.2% reported age, the majority between 20 and 30 years of age. The level of schooling was mentioned in 32.4% ranging from elementary school and higher education. With respect to income, a higher prevalence of low socioeconomic status was observed. About the nutritional status, 45.9% of the studies measured the body mass index and 29.4% reported the predominance of excess weight. There were deficiencies, particularly of vitamin A, with frequencies between 9% and 26%. A majority of young adult mothers, varied schooling, low income and nutritional deficiencies were noted, demanding interventions to improve health and increase HM donations.

Resumo: Este artigo busca analisar os efeitos isolado e combinado de medidas objetivas relativas à segurança da vizinhança, alimentação e ambientes de atividade física sobre a obesidade de crianças em idade escolar. Este estudo transversal foi realizado com crianças de 9 e 10 anos de idade que estavam matriculadas na rede municipal de ensino de uma metrópole brasileira. As medidas objetivas ambientais incluíram a insegurança nos bairros (índices anuais de criminalidade e acidentes de trânsito), disponibilidade de logradouros e espaços públicos para a prática de atividade física e o índice de estabelecimentos que comercializam majoritariamente alimentos ultraprocessados. Um buffer euclidiano de 1.000m em torno da casa das crianças foi tomado como unidade geográfica elegível. Nossa análise englobou os modelos de Análise de Componentes Principais e de Estimação de Equação Generalizada. Análises estratificadas foram realizadas com base na insegurança da vizinhança e na renda familiar da família da criança. Avaliamos 717 estudantes, 12,2% dos quais eram obesos. A variável latente ambiente obesogênico (deduzida das taxas de insegurança ambiental e do índice de estabelecimentos que comercializam majoritariamente alimentos ultraprocessados) constituiu o fator de risco para obesidade em crianças em famílias de baixa renda (OR = 2,37; IC95%: 1,06-5,19). Parques e espaços públicos para a prática de atividade física foram fatores de proteção contra a obesidade infantil apenas nos locais que registraram as menores taxas de insegurança ambiental (OR = 0,30; IC95%: 0,09-0,94). Com base em nossos achados, a condição social modifica o efeito do ambiente sobre a obesidade infantil e reforça a relevância de políticas e estratégias intersetoriais para prevenir a obesidade infantil.

Los parques y espacios públicos para la práctica de actividad física fueron factores de protección contra la obesidad infantil solo en los lugares que registraron las menores tasas de inseguridad ambiental (OR = 0,30; IC95%: 0,09-0,94). Sobre la base de nuestros hallazgos, la condición social modifica el efecto del ambiente sobre la obesidad infantil y refuerza la relevancia de las políticas y estrategias intersectoriales para prevenir la obesidad infantil.

[Healthcare and gestational factors associated with anemia in nursing mothers attended in a human milk bank]. / Fatores assistenciais e gestacionais associados à anemia em nutrizes atendidas em um banco de leite humano.

Anemia is a public health problem that affects about 30% of Brazilian women, which may cause deleterious effects on the health and quality of life of mother and child. This article seeks to evaluate the healthcare and gestational factors associated with anemia among mothers receiving care at a human milk bank (HMB) of reference. It is a cross-sectional study with secondary data about sociodemographic and pregnancy information on 12283 nursing mothers from 2009 to 2012. The Kolmogorov-Smirnov and chi-square or Fisher's exact tests were applied. The prevalence ratios (PR) and their 95% confidence intervals were estimated by Poisson regression with robust variance. Anemia was identified in 29.2% of the sample and the prevalence was higher among mothers who did not have prenatal appointments (PR = 3.84; 95% CI 3.26 to 4.54); those who made 3 or less antenatal visits (PR = 1.92; 95% CI 1.21 to 3.06) and those who have had multiple pregnancies (OR = 2.29, 95% CI 1.25 to 4.19). The results showed a higher prevalence of anemia among women who did not have the appropriate prenatal care and who have had multiple pregnancies, highlighting the importance of healthcare as a factor in the prevention of anemia and other complications during pregnancy.

A anemia é um problema de saúde pública que acomete cerca de 30% das gestantes brasileiras, podendo acarretar efeitos deletérios à saúde e qualidade de vida do binômio mãe-filho. O objetivo deste artigo é avaliar os fatores assistenciais e gestacionais associados à anemia entre nutrizes atendidas em um banco de leite humano (BLH) de referência. Estudo transversal com dados secundários referentes a informações sociodemográficas e gestacionais de 12283 nutrizes no período de 2009 a 2012. Aplicaram-se os testes Kolmogorov-Smirnov e Qui-quadrado ou exato de Fisher. Estimaram-se as Razões de Prevalência (RP) e respectivos Intervalos de Confiança-IC95%, por meio da Regressão de Poisson com variância robusta. Identificou-se a prevalência de anemia em 29,2% da amostra, sendo maior entre as mães que não realizaram o pré-natal (RP = 3,84; IC95% 3,26-4,54); as que realizaram até 3 consultas pré-natais (RP = 1,92; IC95% 1,21-3,06) e aquelas que tiveram gestação múltipla (RP = 2,29; IC95% 1,25-4,19). Os resultados apontaram maior prevalência de anemia entre as mulheres que não realizaram o pré-natal apropriado e as que tiveram gestações múltiplas, destacando-se a importância da assistência à saúde como fator de prevenção à anemia e demais intercorrências gestacionais.

Weight retention 12 months postpartum: association with sociodemographic, gestational and puerperal factors / Retenção de peso 12 meses pós-parto: associação com fatores sociodemográficos, gestacionais e puerperais

Abstract Objectives: to investigate the association between sociodemographic, gestational/puerperal factors and postpartum weight retention (PPWR) after 12 months in Brazilian women at a university hospital. Methods: prospective cohort with puerperal women recruited at the maternity ward of a university hospital in a Brazilian metropolis. At baseline (n=260), sociodemographic and anthropometric information on the mother-child binomial and data related to the gestational period were collected. Maternal dietary patterns were measured using a food frequency questionnaire and subsequently determined by Principal Component Analysis. Results: 75 women, with a mean age of 28.4 years (CI95%= 27.0-29.7), 25.3% with excessive PPPR, with an average of 3.6 kg (CI95%= 1.7) continued in the follow-up. -5.4). Higher gestational weight gain (GWG) (ß= 0.36; CI95%= 0.18-0.70) and lower maternal age (ß= -0.41; CI95%= -0.92--0.22) were PRPP predictors (p=0.001) (adjusted for per capita income, parity, type of delivery, number of prenatal visits, baby's birth weight, breastfeeding and physical activity). Conclusion: there was a high occurrence of excessive PPPR, favored by higher GPG and lower maternal age. This highlights the importance of monitoring women's health during the reproductive period, with guidance on ways of life (diet and physical activity), to favor better outcomes for mother-child.

Resumo Objetivos: investigar a associação entre fatores sociodemográficos, gestacionais/puerperais com a retenção de peso pós-parto (RPPP) após 12 meses em mulheres brasileiras em hospital universitário. Métodos: coorte prospectiva com puérperas recrutadas na maternidade do hospital universitário de uma metrópole brasileira. Na linha de base (n=260) foram coletadas informações sociodemográficas, antropométricas do binômio mãe-filho e dados relativos ao período gestacional. O padrão alimentar materno foi mensurado por meio do questionário de frequência alimentar e posteriormente determinado pela Análise de Componentes Principais. A RPPP foi classificada como risco para obesidade se ≥7,5Kg. Resultados: 75 mulheres continuaram no seguimento, com média de 28,4 anos de idade (IC95%= 27,0−29,7), 25,3% com RPPP excessiva, sendo em média 3,6 Kg (IC95%= 1,7−5,4). Maior ganho de peso gestacional (GPG) (β= 0,36; IC95%= 0,18-0,70) e menor idade materna (β= −0,41; IC95%= −0,92--0,22) foram preditores da RPPP (p≥0,001) (ajustado pela renda per capita, paridade, tipo de parto, número de consultas pré-natal, peso ao nascer do bebê, aleitamento materno e atividade física). Conclusão: evidenciou-se elevada ocorrência de RPPP excessiva, favorecida pelo maior GPG e menor idade materna. Aponta-se assim a importância do monitoramento da saúde da mulher durante o período reprodutivo, com orientações sobre modos de vida (alimentação e atividade física), para favorecer melhores desfechos para mãe-filho.

Comparison between two assessment tools for fruit and vegetable intake relative to the 24-h recall.

OBJECTIVE: The aim of this study was to evaluate the validity of methods assessing fruit and vegetable (FV) intake among Brazilian users of the Primary Attention Health Care Program. METHODS: The present study included 299 participants (age ≥20 y) from a representative sample from a randomized controlled community trial performed as part of a health promotion program in a Brazilian metropolis. All participants completed three methods for the assessment of FV consumption: brief questionnaire of FV (QBrief-FV), food frequency questionnaire of FV, and a 24-h dietary recall. Medians and terciles of FV consumption were compared. Spearman's coefficient, κ, and Wilcoxon's test stratified by sociodemographic and nutritional characteristics were calculated. RESULTS: The population sample was composed of 86.6% women (median age 57 y; range 48-65). Stronger correlations were observed for the evaluation of fruit consumption according to QBrief-FV (r = 0.437) and the median values were comparable to those presented by the 24-h dietary recall (P ≥ 0.05). This comparison also resulted in a higher proportion of terciles with exact concordance (46.1%). All test methods overestimated the consumption of combined FV. CONCLUSIONS: None of the methods tested was very accurate for the assessment of FV consumption. However, the strongest correlation was found for the QBrief-FV evaluation of fruit intake, indicating that it is an appropriate tool for the investigation of fruit consumption.
