It is not always the case that recipe disaggregation is performed in dietary surveys. This investigation aimed to assess the influence of recipe disaggregation in the 2020-2021 national dietary survey in Saint Kitts and Nevis, and provide recommendations for future assessments. A total of 1,004 individuals provided information on their food consumption obtained using 24-h dietary recalls, and 442 recipes were reported. Some recipes were reported as single ingredients at the data collection stage ( n = 65). In most cases, the respondent provided a standard recipe without disaggregation ( n = 377). A simple and pragmatic recipe disaggregation methodology was developed. The procedure of recipe disaggregation comprised nine steps, including identifying recipes, ingredients, quantities, conversion factors, and the presence of visible fluid, among others. Seventy-eight non-disaggregated standard recipes were post-disaggregated (21% of recipes) to identify ingredient weights. Either the chi-square or Fisher's exact tests were applied to assess the significance of differences in frequency of food group consumption before and after disaggregation. The proportion of consumers across the different food groups increased dramatically for some food groups after recipe disaggregation, with significant differences (all p < 0.01) for cereals and their products (81.3% before and 94.7% after), eggs and their products (21.7% before and 34.6% after), fats and oils (6.9% before and 44.5% after), fish, shellfish and their products (26.7% before and 38.5% after), meat and meat products (59.7% before and 71.4% after), milk and milk products (30.4% before and 46.1% after), pulses, seeds, nuts and their products (18.6% before and 49.2% after), spices and condiments (34.0% before and 68.5% after, and vegetables and their products (49.9% before and 76.6% after). Consequently, most of the reported intakes in grams were also influenced across all food groups. Recipes are an important source of food consumption, and their disaggregation should be carefully considered in dietary assessment., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Crispim, Elias, Matthew-Duncan, Francis-Grandeson, Jean, de Quadros, Balcerzak, de Sousa, Frauches, Almeida, Hutchinson, Charrondière and Holmes.)

Next-generation sequencing (NGS), comprising targeted panels (TP), exome sequencing (ES), and genome sequencing (GS) became robust clinical tools for diagnosing hereditary ataxia (HA). Determining their diagnostic yield (DY) is crucial for optimal clinical decision-making. We conducted a comprehensive systematic literature review on the DY of NGS tests for HA. We searched PubMed and Embase databases for relevant studies between 2016 and 2022 and manually examined reference lists of relevant reviews. Eligible studies described the DY of NGS tests in patients with ataxia as a significant feature. Data from 33 eligible studies showed a median DY of 43% (IQR = 9.5-100%). The median DY for TP and ES was 46% and 41.9%, respectively. Higher DY was associated with specific phenotype selection, such as episodic ataxia at 68.35% and early and late onset of ataxia at 46.4% and 54.4%. Parental consanguinity had a DY of 52.4% (p = 0.009), and the presumed autosomal recessive (AR) inheritance pattern showed 62.5%. There was a difference between the median DY of studies that performed targeted sequencing (tandem repeat expansion, TRE) screening and those that did not (p = 0.047). A weak inverse correlation was found between DY and the extent of previous genetic investigation (rho = - 0.323; p = 0.065). The most common genes were CACNA1A and SACS. DY was higher for presumed AR inheritance pattern, positive family history, and parental consanguinity. ES appears more advantageous due to the inclusion of rare genes that might be excluded in TP., (© 2023.

Acute leukemia commonly occurs in young children with peak incidence at the age of 2-5 years. However, the etiology is still unclear and many preventable risk factors still deserve to be reviewed. The focus of this systematic review and meta-analysis is to summarize the evidence concerning early life nourishment (breastfeeding, early life diet), neonatal vitamin K administration and the risk of acute leukemia. All epidemiological studies published up to June 2023 and assessing diet-related risk factors for childhood acute leukemia were identified in two electronic databases (PubMed and Web of Science), with no limits on publication year or language. A total of 38 studies (37 case-control studies and 1 study with pooled analysis) were included. The published risk estimates were combined into a meta-analysis using the Generic Inverse Variance method. The current evidence shows that breastfeeding (yes vs. no) has a protective effect against acute lymphoblastic leukemia (odds ratio = 0.85; 95% CI, 0.76-0.94). Evidence related to the role of other studied factors (foods and supplements) is inconclusive. Further research into the potential role of diet in early life and the risk of acute leukemia is needed to develop prevention strategies at population level.

The dietary exposure of six food azo-colours was assessed in a sample of pre-schoolers from Guaratuba-Paraná, Brazil. Consumption data of 323 children aged 2 to 5 years was collected through 3-day food records. Dietary exposure, is expressed by milligrams of food colour by kilogram of body weight per day, as compared to the Acceptable Daily Intake (ADI). Three exposure scenarios were developed to account for uncertainties around consumption estimates. Intakes of Amaranth (INS 123) described in means, 50th and 95th percentiles exceeded ADI levels in the two most conservative scenarios, with the highest percentiles exceeding about four times the ADI. High intakes of Sunset Yellow FCF (INS 110) were also observed, of up to 85% of the ADI in the worst-case scenario. Findings suggest high exposure levels to azo-dyes in the survey population, with children likely exceeding the ADI for Amaranth (INS 123) and concerns for Sunset Yellow FCF (INS 110). Major food contributors were beverages (juice powders and soft drinks), dairy and sweets. Further studies on dietary exposure assessment are needed at the national level. The authors highlight the need of controlling the use of such additives through national policies that are aligned with the consumption patterns observed in the country.

Objective: The present study aimed to evaluate the effects of GH treatment on the body composition of children born with SGA., Methods: This study is a systematic review of the literature. CINAHL, Embase; Medline/Pubmed, Scopus and Web of Science were searched from inception to March 2022., Results: Four studies met the inclusion criteria, with an intervention time of 1 to 3 years, using doses from 0.03 to 0.07 mg/kg/day of GH. Bone densitometry by dual-energy X-ray absorptiometry (DXA) with whole-body scans was the most used method to assess body composition. Most studies (n = 3) had SGA children as a control group with the same characteristics as the case group; the mean age was similar between the groups (minimum of 5.1 ± 1.4 years and maximum of 6.7 ± 1 0.8 years) and all participants had an average height ≤ -3DP. The Lean Mass (LM) and Fat Mass (FM) outcomes of the studies were not presented in a standardized manner; thus, they cannot be compared. There was a significant increase in LM in the group treated with GH in relation to the pre-treatment period and in comparison, to the untreated control group. Three studies showed a significant decrease in FM at the end of the intervention period, and in two studies, this decrease occurred in the control group., Conclusions: Despite the differences in the presentation of results and in the evaluation periods, the results of the studies showed that growth hormone favors the gain and maintenance of lean mass, and it also affects fat mass reduction and redistribution., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2022 Sociedade Brasileira de Pediatria.

Many studies have investigated the etiology of acute leukemia, one of the most common types of cancer in children; however, there is a lack of clarity regarding preventable risk factors. This systematic review and meta-analysis aimed to summarize the current evidence regarding the role of maternal dietary factors in the development of childhood leukemia. All epidemiological studies published until July 2022 that evaluated maternal dietary risk factors for childhood acute leukemia were identified in two electronic databases (PubMed and Web of Science) without limits of publication year or language. A total of 38 studies (1 prospective cohort study, 34 case-control studies and 3 studies with pooled analysis) were included. The published risk estimates were combined into a meta-analysis, using the Generic Inverse Variance method. The maternal consumption of fruits (two or more daily servings vs. less) was inversely associated with acute lymphoblastic leukemia (odds ratio = 0.71; 95% CI, 0.59-0.86), whereas maternal coffee intake (higher than two cups per day vs. no consumption) was associated with an increased risk of acute lymphoblastic leukemia (odds ratio = 1.45; 95% CI, 1.12-1.89). Despite these findings, more high-quality research from cohort studies and the identification of causal factors are needed to develop evidence-based and cost-effective prevention strategies applicable at the population level.

(1) Measuring usual iodine intake is a complex task due to the food consumption variability and its natural concentration in food. Therefore, the use of covariates to adjust statistical methods to estimate usual intake could improve the estimates obtained through dietary surveys. This study aims to evaluate the influence of salt and seasoning usage covariates on the estimates of usual iodine intake and the prevalence of its inadequacy. (2) A cross-sectional study was conducted with Brazilian pregnant women's food consumption data obtained with 24-h recall ( n = 2247). The usual iodine intake was adjusted for intraindividual variability, supplement use, temporal effects, data collection methods, and sociodemographic characteristics with the tool UCD/NCI SIMPLE in the SAS software. Then, salt and seasoning usage covariates were used to adjust the distribution. The harmonized intake reference values for populations were used to assess intake adequacy. (3) The adjustments for salt and seasoning usage yielded a higher mean of usual iodine intakes. The only exception was the adjustment for the "habit of adding salt to meals after preparing/cooking", which produced a lower mean of usual intake and increased the prevalence of insufficient intake. (4) Salt and seasoning usage covariates affect the estimates evaluated. However, more studies are necessary to evaluate the influence observed.

The dietary exposure to low-calorie sweeteners (LCS) was estimated in a sample of pregnant Brazilian women. Consumption data were obtained with a 24-h Dietary Recall interview. Because of the uncertainty in assessing foods with LCS, they were classified into three scenarios to ensure inclusion of the 15 LCS allowed for use in Brazil: ranging from a less to a more conservative scenario. The concentration of LCS was estimated using the amount declared on the label or the maximum permitted levels and analytical determination data for table-top sweeteners. The frequency of consumption was higher for acesulfame-K, aspartame, and cyclamate. The food groups contributing the most to the consumption of LCS were non-alcoholic beverages, table-top sweeteners, confectionary and desserts. The level of dietary exposure to LCS was within the safety limit. However, continued efforts to monitor their dietary exposure are necessary given the limitations highlighted in this study.

Objective: To identify the dietary patterns and associated factors of children aged between 6 and 23 months, born prematurely and assisted at a University Hospital in Curitiba, state of Paraná, Brazil., Methods: The parents or guardians of the 135 children were asked about their children's eating habits and the family's socioeconomic and demographic conditions. Information regarding birth and health history were obtained from medical records. Data on food consumption were subjected to exploratory factor analysis and the principal component analysis method was used to estimate the factor loads. Multiple linear regression was performed to verify possible associations., Results: Two dietary patterns were observed: "unhealthy" and "healthy." The "unhealthy" pattern was significantly associated with maternal age, the child's corrected age, and gestational age at birth. The "healthy pattern" was associated with the child's corrected age. Maternal age and child's corrected age remained significant after multiple regression analyses. For the "unhealthy" pattern, a positive effect was observed, suggesting that the consumption of this pattern is higher as the child's age increases and less intense for children with mothers aged 30 years or older. For the "healthy" dietary pattern, the same two variables showed statistical significance. The authors observed a direct proportion between the age and consumption of food groups in both patterns., Conclusions: These results indicate the importance of nutritional education for younger mothers regarding their children's eating practices, especially as the child grows.

Objective: To assess the consumption of food groups among children aged 6 to 23 months in day care centers and at home and its associated factors., Methods: This is a population-based cross-sectional study conducted with children from nursery schools in Guaratuba, Paraná. Parents answered a socioeconomic and demographic questionnaire. Food consumption was assessed by directly weighing the meals offered at the day care center. At home, parents filled an estimated food record. The reported foods were classified into seven food groups. Minimum dietary diversity was calculated by the proportion of children who consumed foods from four or more groups. Data were analyzed by simple and multiple logistic regression, presented as odds ratios., Results: A total of 213 children participated in this study. The average number of food groups consumed was 4.2±1.0 at home and 4.2±1.2 in day care centers. At the day care center, all children consumed grains, roots, and tubers, while at home, this rate was 99.1%. The egg group was the least consumed both at day care (6.6%) and at home (2.8%). At home, more than 60% of children consumed sweets and sugar-sweetened beverages. Children aged 12 to 23 months were more likely to consume milk and dairy products, as well as flesh foods. Higher income was associated with the consumption of legumes, and older maternal age with the consumption of fruits and vegetables., Conclusions: At home, children had a predominantly dairy-based diet and a high intake of ultra-processed foods. In day care centers, the consumption of healthy foods was higher, indicating the need for families to participate in the formation of healthy eating habits.

Objective: The objective of the review is to evaluate the effectiveness of green tea extract (Camellia sinensis) capsule supplementation compared with placebo for post-exercise muscle pain and muscle recovery in healthy adults., Introduction: Green tea extract is popularly consumed by athletes and practitioners of physical activity, as it is easily accessible in supermarkets and health food stores. It is a source of catechins, which assist the endogenous antioxidant system in combating free radicals produced during exercise that can lead to oxidative stress and, therefore, muscle damage and delayed-onset muscle pain. However, there is no consensus on the effect of green tea extract and the ideal and safe dosage to promote muscle recovery., Inclusion Criteria: Studies on the effectiveness of supplementation with green tea extract capsules compared with placebo in post-exercise muscle pain and muscle recovery in healthy adults will be included. Studies that are associated with any other source of polyphenols with green tea extract will be excluded., Methods: Studies will be identified using the following databases: Cochrane Library, PubMed, Embase, Web of Science, Virtual Health Library, SPORTDiscus, Science Direct, and Scopus. OpenGrey, DART-Europe, and Google Scholar will be used to identify unpublished studies. Studies published in English, French, Spanish, or Portuguese will be included. There will be no restriction on the date of publication. Two authors will independently screen titles and abstracts following previously defined eligibility criteria. After excluding irrelevant studies, the authors will read the full texts of any articles potentially eligible for further evaluation. Any disagreements will be resolved by discussion or by consulting a third author. The included studies will be assessed on their methodological quality using the appropriate JBI critical appraisal checklist, and the data will be extracted by the two authors. A meta-analysis will be performed using a random effects or fixed effects model. The heterogeneity of the data will be calculated. This review will follow the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) to classify the certainty of the evidence., Systematic Review Registration Number: PROSPERO CRD42020138772., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 JBI.)

Identifying dietary patterns in different environments attended by children is relevant to guide public politics. The aim of this study was to analyse the factors associated with dietary patterns of children under 2 years of age in childcare centres and at homes. This transversal study was enrolled in municipal childcare centres of Guaratuba, Paraná, Brazil. Food consumption data from 256 children were obtained by the food record method. From the consumption data, four dietary patterns were identified by factor analysis using the principal component method in each environment. 'Traditional' patterns were observed in both environments; the 'less healthy' pattern was found only at homes. Other patterns identified in childcare centres include 'snacks', 'nutritive' and 'pasta and meats'; at homes, it was possible to identify patterns such as 'milk and cereals' and 'mixed'. Children over 12 months presented higher scores for all the patterns in both environments. Obese children had lower scores for all the patterns in childcare centres. There was an association between maternal age below 21 years and higher adherence to a 'less healthy' pattern, maternal level of education less than 8 years and lower adherence to the 'mixed' pattern and lower familiar income per capita and higher adherence to the 'snacks' and 'traditional' patterns in childcare centres. In conclusion, adherence to dietary patterns was associated with socio-economic, demographic variables and nutritional status and further studies are needed, especially those with a longitudinal design, enabling the monitoring of dietary patterns., (© The Author(s) 2021.)

Objective: To compare the values of the markers for volumetric capnography and spirometry and their ability to classify children and adolescents with asthma, cystic fibrosis (CF), and healthy controls., Methods: This was a cross-sectional study that included 103 patients with controlled persistent allergic asthma, 53 with CF and a healthy control group with 40 volunteers (aged 6 to 15 years), of both sexes. The individuals underwent volumetric capnography and spirometry., Results: Phase III slope (SIII), SIII standardized by exhaled tidal volume (SIII/TV) and capnographic index (SIII/SII)×100 (KPIv) were different among the three groups assessed, with highest values for CF. The relation between the forced expiratory volume in one second and the forced vital capacity (FEV 1 /FVC) was the only spirometric marker that presented difference on the three groups. On individuals with normal spirometry, KPIv and FEV 1 /FVC were different among the three groups. The ROC curve identified the individuals with asthma or CF from the control group, both through volumetric capnography (better to identify CF in relation to the control using KPIv) and through spirometry (better to identify asthma in relation to the control). KPIv was the best parameter to distinguish asthma from CF, even in individuals with normal spirometry., Conclusion: Volumetric capnography and spirometry identified different alterations in lung function on asthma, CF, and healthy controls, allowing the three groups to be distinguished., (Copyright © 2018 Sociedade Brasileira de Pediatria.

Objective Evaluate the efficacy of Noninvasive Mechanical Ventilation (NIV) in preventing Endotracheal Intubation (ETI) in a heterogeneous pediatric population and identify predictive factors associated with NIV failure in Pediatric Intensive Care Unit (PICU). Methods Prospective non-randomized clinical trial conducted with patients aged 0-10 years, hospitalized in a PICU with NIV indication, who presented acute or chronic respiratory failure. Demographic data and clinical and cardiorespiratory parameters were evaluated, and patients who did not progress to ETI in 48 h after withdrawal of NIV were classified as "success group", whereas those who progressed to ETI were included in the "failure group". Multivariate logistic regression was performed to identify the predictive factors of failure to prevent ETI. Results Fifty-two patients, 27 (51.9%) males, with median age of 6 (1-120) months were included in the study. When evaluating the effectiveness of NIV, 36 (69.2%) patients were successful, with no need for ETI. After analyzing the predictive factors associated with failure, patients with tachypnea after 2 h of NIV were 4.8 times more likely to require ETI in 48 h. Regardless of outcome, heart (p<0.001) and respiratory (p<0.001) rates decreased and oxygen saturation (p<0.001) increased after 2 h of NIV. Conclusion We concluded that use of NIV was effective in the studied population, with significant improvement in cardiorespiratory parameters after 2 h of NIV, and that tachypnea was a predictive factor of failure to prevent ETI.

Introduction: Cardiovascular diseases are the main cause of mortality and disability worldwide, so the prevention becomes a priority in terms of public health. Therefore, it is necessary to use validated strategies to adequately identify these patients in daily clinical practice. The objective of this scope review is to comprehend and comprehensively describe the anthropometric indicators used in studies, such as such as weight, height, circumferences, lengths and skin folds, that address its association with coronary artery calcification to identify cardiovascular risk in the adult population., Methods and Analysis: Using Arksey and O'Malley's scoping review methodology as a guide, our scoping review of published reviews begins by searching several databases: Cochrane Central Register of Controlled Trials in the Cochrane Library, Medline Complete (EbscoHost), Embase, LILACS (Literatura Latino-Americana e do Caribe em Ciências da Saúde-BIREME Literatura Latino-Americana e do Caribe em Ciências da Saúde)and Web of Science and Scielo. As well as, it will be searched in the International Platform of the Registry of Clinical Trials of the WHO (www.who.int/ictrp); ClinicalTrials.gov; Transforming Research into Practice. Our team has formulated search strategies and two reviewers will independently screen eligible studies for final study selection. Bibliographic data and abstract content will be collected and analysed using a tool developed iteratively by the research team., Ethics and Dissemination: This protocol reports a comprehensive, rigorous and transparent methodology. This scoping review will be the first study to compare anthropometric measurements and coronary artery calcification, and thereby will contribute to the design and comparison of future studies in this field. This protocol reports a comprehensive, rigorous and transparent methodology. The results will be disseminated through a peer-reviewed publication. By identifying gaps in the current body of literature, this study can guide future research., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Although digital photos have the potential to improve the precision of reported portions in dietary assessment, there are few studies investigating its accuracy in comparison to printed photos. The aim of this study was to evaluate the perception of adults in quantifying food portion sizes using printed and digital photos, displayed on computer-screens and tablets. In total, 1165 evaluations were performed for 60 photos of portion sizes in Brazil. Each participant ( n = 58) attended two sessions in the study center, with an interval of at least one week. In each session, twelve food portions were prepared and randomly evaluated by each participant in its printed and digital forms. The mean error (difference between the estimated and true portions) was not significantly different between the printed photos (2.1 g ± 47.2) and the digital ones (-6.4 g ± 53.7). The agreement on using the printed and digital photos was 91% and 90%, respectively. Furthermore, the use of the tablet was more prone to underestimation when compared to printed and computer-screen photos ( p < 0.001). Overall, participants did not present major difficulties in perceiving the portion sizes using the printed and digital photos, but the use of tablets led to less accurate results, indicating that this needs to be further evaluated.

Breastfeeding is a multifaceted phenomenon involving the complexity of the social world, the roles assumed by women, their attributes and social expectations. This theoretical essay proposes a reflection on motherhood, problematizing the experience of breastfeeding and the construction of social identity in line with Anselm Levi Strauss's sociological concepts of interactionism. This article sought to make associations between body, identity, and socialization processes in adulthood, generated by new social demands in fulfilling the roles of woman and mother, focusing on the breastfeeding experience. The way motherhood is conceived in contemporary society and the register of breastfeeding as a phenomenon of nature are problematized to give the woman a vocation to motherhood and breastfeeding, producing a social expectation of the innate ability to perform them.

Background: Invasive mechanical ventilation (IMV) is a common practice in pediatric intensive care unit (PICU). However, the role of oxygenation (OI) and ventilation (VI) indices regarding the time on IMV has not been fully understood., Basic Procedures: The study was conducted with infants up to 24 months of age, hospitalized in PICU for two consecutive years. The values of ventilatory parameters, OI, VI, and blood gas of infants, collected in the first seven days in IMV, were associated with the time on IMV. IMV was classified into: short (≤seven days) and long time (>seven days). The comparison was made from the first to the seventh day. Alpha=0.05., Main Findings: Of 142 infants [mean age=7.51±6.33 months], 59 (41.5%) remained on IMV for a short time and 83 (58.5%) for a long time. Differences in PaO 2 values were found on the second day, and PaO 2 /FiO 2 ratio on the second, third and fourth days, with higher values in the short-term IMV. For FiO 2 from the second to the fifth day; Pinsp from the first to the seventh day; PEEP from the second to the sixth day; mechanical respiratory frequency from the second to the seventh day, PaCO 2 on the second day; Paw from the first to the seventh day, OI from the second to the sixth day, and VI from the first to the seventh day, the values were higher in the long-term IMV., Conclusions: The OI and VI can be considered as potential predictors of long-term IMV, along with other markers obtained during the IMV., (Copyright © 2017 Sociedade Portuguesa de Pneumologia.

This paper is an integrative review of the literature that sought to identify the factors that influence the adhesion and acceptance of school food among Brazilian and American students, and to show the main differences between the programs of these two countries. the following databases were consulted: Latin American and Caribbean Health Sciences (Lilacs); Pubmed; Scientific Electronic Library Online (Scielo); and Science Direct. Data were collected between July and August 2015, using the following key words in Portuguese and English: "adherence to school food" (adesão à alimentação escolar), "accepting of school feeding" (aceitação à alimentação escolar) and the "National School Lunch Program" ("Programa Nacional de Alimentação Escolar"). The search resulted in 7 Brazilian articles and 7 Americans articles published between 2004 and 2014, besides the current laws of each program, selected in the electronic sites of agencies responsible for administrating them. After descriptive and comparative analysis, the results revealed that adherence and acceptance are low in both programs, and they are influenced by socioeconomic factors, competitive foods present in the school environment and students' food preferences.

Background: Acute viral bronchiolitis is the leading cause of hospitalization among infants during the first year of life. Most infants hospitalized for bronchiolitis do not present risk factors and are otherwise healthy. Our objective was to determine the genetic features associated with the risk and a severe course of bronchiolitis., Methods: We prospectively evaluated 181 infants with severe bronchiolitis admitted at three hospitals over a 2-year period, who required oxygen therapy. The control group consisted of 536 healthy adults. Patients were evaluated for the presence of comorbidities (premature birth, chronic respiratory disease, and congenital heart disease), underwent nasopharyngeal aspirate testing for virus detection by multiplex-PCR, and SNPs identification in immune response genes. Patient outcomes were assessed., Results: We observed association between SNP rs2107538*CCL5 and bronchiolitis caused by respiratory syncytial virus(RSV) and RSV-subtype-A, and between rs1060826*NOS2 and bronchiolitis caused by rhinovirus. SNPs rs4986790*TLR4, rs1898830*TLR2, and rs2228570*VDR were associated with progression to death. SNP rs7656411*TLR2 was associated with length of oxygen use; SNPs rs352162*TLR9, rs187084*TLR9, and rs2280788*CCL5 were associated with requirement for intensive care unit admission; while SNPs rs1927911*TLR4, rs352162*TLR9, and rs2107538*CCL5 were associated with the need for mechanical ventilation., Conclusions: Our findings provide some evidence that SNPs in CCL5 and NOS2 are associated with presence of bronchiolitis and SNPs in TLR4, TLR2, TLR9, VDR and CCL5 are associated with severity of bronchiolitis., (Copyright © 2017 Elsevier B.V.

This study aimed to estimate the prevalence of adherence to school meals and associated factors among adolescent schoolchildren (N = 1,569). The adolescents completed an on-line questionnaire on adherence to school meals, and their parents answered another questionnaire on socioeconomic data. The chi-square test was used to assess the association between adherence to school meals and gender, nutritional status, per capita family income, maternal schooling, adolescents' opinions on the dining hall layout, whether they considered school meals healthy, and consumption of other foods. Variables with statistical significance for adherence to school meals were included in the multilevel proportional odds logistic regression model. The covariates for comprising the final model were defined by backward selection methods. The results of the adjusted model were presented as odds ratios with respective 95% confidence intervals (95%CI). Prevalence of adherence to school meals was low, especially effective adherence (19.8%). Adherence was associated with per capita family income less than one minimum wage, lower consumption of foods outside of school meals, the fact that adolescents considered the dining hall space adequate, and believing that school meals are healthy. Adherence to school meals in this study falls short of universal coverage for the program. Different factors contribute to incomplete program implementation, which may hinder achieving the food and nutritional security policy under the Brazilian National School Feeding Program (PNAE).
