Introducción: los cambios de conductas saludables a las no saludables ponen en riesgo la salud, los universitarios son una población muy vulnerable para adoptar estilos de vida que puedan favorecer su calidad de vida. El consumo de alcohol y tabaco como conducta es un tema importante en esta etapa de formación profesional. Objetivo: determinar las conductas de estilo de vida relacionados con la salud como el consumo de cigarrillos, alcohol y drogas, hábitos alimentarios, forma física, control del estrés y seguridad que realizan los estudiantes de la Licenciatura en Enfermería de la Universidad Juárez Autónoma de Tabasco, México. Metodología: estudio de tipo cuantitativo, descriptivo, transversal en una muestra de 666 estudiantes de la Licenciatura en Enfermería seleccionados por muestreo no probabilístico. Resultados: predominó el género femenino con 83%, el 62.8% presenta un buen estilo de vida, seguido del 30.3% que tiene un excelente estilo de vida; el 79.1% corresponde a los estudiantes que no fuman y el 37.8% de los estudiantes tiene una buena alimentación. Los estudiantes calificaron su forma física como regular en el 41% de los casos, seguida de mala con el 34.5%. En cuanto a la práctica de control del estrés calificaron como buena con un 50.8% y excelente con 26.1%. Conclusión: los estudiantes de Enfermería tienen un nivel de estilo de vida bueno relacionado con la salud, los más practicados corresponden a las dimensiones de consumo de alcohol, hábitos alimentarios, control de estrés y seguridad. Es importante considerar la dimensión relacionada con la forma física (práctica de ejercicio físico), ya que se practica ocasionalmente, lo que demuestra que los estudiantes llevan un estilo de vida sedentario.

Introduction: Changes from healthy to unhealthy behaviors put health at risk, so university students are a very vulnerable population to adopt lifestyles that can favor their quality of life. The consumption of alcohol and tobacco as conduct is an important issue at this stage of professional training. Objective: To determine the lifestyle behaviors related to health such as the consumption of cigarettes, alcohol and drugs, eating habits, physical fitness, stress control and safety carried out by the students of the Bachelor of Nursing at the Universidad Juárez Autónoma de Tabasco, in Mexico. Methodology: Quantitative, descriptive, cross-sectional study in a sample of 666 Nursing undergraduate students selected by non-probabilistic sampling. Results: The female gender predominated with 83%, 62.8% have a good lifestyle, followed by 30.3% who have an excellent lifestyle; 79.1% corresponds to students who do not smoke and 37.8% of students have a good diet. The students rated their physical fitness as fair in 41% of the cases, followed by poor with 34.5%. Regarding the practice of stress control, they qualified as good with 50.8% and excellent with 26.1%. Conclusion: Nursing students have a good level of lifestyle related to health, the most practiced correspond to the dimensions of alcohol consumption, eating habits, stress control and safety. It is important to consider the dimension related to physical fitness (practice of physical exercise), since it is only practiced occasionally, which shows that students lead a sedentary lifestyle.

Alteração na representação de subpopulações de neurônios no epitélio olfatório de camundongos Ric8b cKO / Altered representation of neuronal sub-populations in the olfactory epithelium of Ric8b conditional knock-out mice

O objetivo desse trabalho foi identificar as consequências moleculares e funcionais da falta da proteína Ric8b no epitélio olfatório de camundongos. Para esse fim, comparamos o transcriptoma de epitélio olfatório de camundongos knock-out tecido específico para a proteína RIC8B (Ric8b cKO) com o dos seus irmãos tipo selvagem (WT). Identificamos muitos genes que apresentaram expressão reduzida no epitélio olfatório do camundongo Ric8b cKO, mas também vários genes que apresentaram a sua expressão aumentada. A maioria dos genes com expressão reduzida corresponde a genes normalmente expressos em neurônios olfatórios maduros, como por exemplo os genes de receptores olfatórios, o que é compatível com o fato já conhecido de que os camundongos Ric8b cKO apresentam um menor número desses neurônios. Inesperadamente, apesar de a maioria dos genes de receptores olfatórios ter a sua expressão diminuída no camundongo Ric8b cKO, observamos que um grupo destes genes de receptores teve a sua expressão aumentada. Os camundongos Ric8b cKO apresentaram também genes marcadores de outros tipos celulares que não neurônios canônicos com expressão aumentada no seu epitélio olfatório. Dentre eles, os mais significativamente alterados foram os genes marcadores de neurônios Trpc2+ tipo B (que expressam a guanilato ciclase solúvel Gucy1b2). Sabe-se que este tipo de neurônio é responsável pela sensibilidade a diferentes gases, e concordantemente, observamos que os camundongos Ric8b cKO apresentaram um aumento da sensibilidade a gás carbônico. Como o olfato apresenta um papel importante na regulação de ingestão alimentar, analisamos como os camundongos Ric8b cKO se comportam frente a diferentes dietas. Interessantemente, observamos que esses animais não apresentam preferência por alimento rico em gorduras quando comparado aos seus irmãos tipo selvagem. Nossos resultados sugerem, portanto, que a ausência da proteína RIC8B resulta na alteração de representatividade de neurônios canônicos e não canônicos no epitélio olfatório de camundongos, o que por sua vez leva a alterações funcionais e comportamentais

The objective of this work was to identify the molecular and functional consequences of the lack of the RIC8B protein in the main olfactory epithelium of mice. To this end, we compared the olfactory epithelium transcriptome of Ric8b tissue-specific knock-out mice (Ric8b cKO) with that of their wild-type littermates (WT). We identified many genes with differential expression, many of which were downregulated and also some which were upregulated in the olfactory epithelium of the Ric8b cKO mice. Most of the downregulated genes correspond to genes normally expressed in mature olfactory sensory neurons, such as olfactory receptor genes. This is compatible with the already known fact that the Ric8b cKO mice have less of this kind of neuron. Unexpectedly, even though most of the olfactory receptor genes were downregulated, we observed a subset of these genes that had their expression upregulated in the Ric8b cKO mice. The Ric8b cKO mice also showed upregulation for genes that are markers for cell types other than canonic neurons in their olfactory epithelium. Among these, the most significantly altered were the markers for neurons Trpc2+ type B (that express the soluble guanylate cyclase Gucy1b2). It is known that this kind of neuron is responsible for sensitivity to different gases. Accordingly, we observed that the Ric8b cKO mice presented a higher sensitivity to carbon dioxide. Since olfaction has an important role in food intake, we analyzed how the Ric8b cKO mice behaved with different diets. Interestingly, we observed that the Ric8b cKO mice lack preference for high fat diet when compared to their wild-type littermates. Our results indicate, therefore, that the lack of the RIC8B protein results in altered representativity of canonic and non-canonic neurons in the olfactory epithelium of mice, which then leads to altered function and behavior

Temporal and spatial isotopic variability of marine prey species in south-eastern Australia: Potential implications for predator diet studies.

Stable isotope analyses, particularly of carbon (δ13C) and nitrogen (δ15N), are used to investigate ecological relationships among species. For marine predators, research has shown the main factors influencing their intra-specific and intra-individual isotopic variation are geographical movements and changes in the composition of diet over time. However, as the differences seen may be the result of changes in the prey items consumed, a change in feeding location or the combination of both, knowledge of the temporal and spatial consistency in the isotopic values of prey becomes crucial for making accurate inferences about predator diets. This study used an abundant marine predator, the Australasian gannet (Morus serrator), as prey sampler to investigate the annual variation in fish and squid prey isotope values over a four-year period (2012-2015) and the geographic variation between two sites with contrasting oceanographic conditions. Significant inter-annual variation was observed in δ13C and/or δ15N values of five of the eight prey species analysed. The strongest inter-annual variation in both δ13C and δ15N values occurred in 2015, which coincided with a strong El Niño-Southern Oscillation (ENSO). This may suggest a temporal fluctuation in the geographic source of prey or the origin of their nutrients. These results suggest that it is important to consider the potential significant differences in isotopic values within the prey assemblages that predators consume. This is important to improve the interpretation of marine predator isotope results when determining the influence of environmental variability on their diets.

Associations of maternal characteristics and dietary factors with anemia and iron-deficiency in pregnancy.

OBJECTIVE: Anemia and iron deficiency during pregnancy influence maternal and fetal health, birth outcomes, and the risk of chronic disease in offspring. This study aimed to examine the association with sociodemographic, maternal factors, supplement use and dietary intakes, and anemia and iron deficiency in pregnancy. METHODS: A cross-sectional study was conducted on 165 pregnant women aged between 19 and 45 years who were interviewed, and dietary intake was assessed by 24-hours dietary recall, supplement records and food frequency questionnaire. Learning Vector Quantization feature selection method which is one of the machine learning techniques was used to extract important variables from sociodemographic, maternal, and dietary factors. RESULTS: The prevalence of anemia was 15.2% and prevalence of iron deficiency was 65.5%. Total intake of iron, phosphorus, vitamin B1 and B2 were importance factors for iron deficiency while age, number of births, use of folic acid supplement, dietary folate equivalent and total iron intake were importance factors for anemia. CONCLUSIONS: Maternal and dietary characteristics were the most crucial risk factors for anemia while dietary factors were the most important risk factor for iron deficiency in pregnancy. The development of anemia and iron deficiency is associated with the coexistence of many nutrient deficiencies.

The Association Between Dietary Pattern Adherence, Cognitive Stimulating Lifestyle, and Cognitive Function Among Older Adults From the Quebec Longitudinal Study on Nutrition and Successful Aging.

OBJECTIVES: This study examined the effect of dietary patterns and engagement in cognitive stimulating lifestyle (CSL) behaviors on the trajectory of global cognition, executive function (EF), and verbal episodic memory (VEM). METHODS: Western and prudent dietary patterns were empirically derived using food frequency questionnaire responses from 350 community-dwelling older adults (mean age: 73.7 years) participating in the Quebec Longitudinal Study on Nutrition and Successful Aging. CSL was represented by a binary composite indicator based on education, occupational complexity, and social engagement. Global cognition, EF, and VEM were assessed prospectively. RESULTS: Primary effect models revealed an association between higher Western dietary pattern score and a greater rate of decline in global cognition and EF. Higher Western dietary pattern adherence was also associated with poorer baseline VEM. Primary effect models also revealed that CSL was independently associated with baseline global cognition and EF. Effect modification models suggested an interactive effect between Western dietary pattern and CLS on global cognition only. No associations were found for prudent dietary pattern score. DISCUSSION: Contributing to existing research supporting the negative impact of consuming an unhealthy diet on cognitive function, the current study suggests increased vulnerability among older adults who do not engage in a CSL. These findings can inform the development of lifestyle intervention programs that target brain health in later adulthood.

Protocol for a Binary Choice Feeding Assay Using Adult, Axenic Drosophila.

This protocol is designed to prepare adult axenic Drosophila before monitoring their behavior in a two-choice feeding assay, where flies are confronted with an axenic versus a dead or alive bacteria-contaminated feeding solution. Several aspects of the procedure, including raising and aging flies in axenic conditions, starving adult flies, and composing feeding solutions, are detailed. The bacterium used in this protocol, Erwinia carotovora carotovora-15 2141 (Ecc-15 2141 ), is commonly used to decipher the mechanisms controlling host-pathogen interactions in the Drosophila model. For complete details on the use and execution of this protocol, please refer to Charroux et al. (2020).

Profile of nursing students: quality of life, sleep and eating habits.

OBJECTIVE: to profile and analyze sleep quality, quality of life and eating habits of nursing students. METHODS: a cross-sectional, comparative and correlational study with the following variables: sociodemographic characteristics, Pittsburgh sleep quality index, quality of life and eating habits. One hundred ninety-five students participated in the study. RESULTS: participants were on average 24 years old. Results showed that females were prevalent (87.1%); 71.0% of the students had poor sleep quality; 98.9% used electronic devices before bedtime. Self-perception of quality of life was indifferent (38.3%), and self-perception of general health, 36.9% expressed satisfaction. Among the participants, 45.13% consumed one portion of fruit and 40.66% two to three portions of vegetables daily. CONCLUSION: the study allowed the profile of these students, sedentary, overweight and poor sleep quality young students who studied and worked.

Establishing a Foundation for Optimal Feeding Outcomes in the NICU.

Many infants in the NICU experience difficulties with oral feeding, which contribute to prolonged length of stay. Oral feeding is a complex task involving sensorimotor functioning of the face, mouth, and larynx, as well as coordination of sucking, swallowing, and breathing. The care provided in the NICU starting at birth sets the stage for future oral feeding. The purpose of this article is to describe strategies that will establish a positive foundation to support optimal oral feeding. Nurses can use these strategies to protect newborns from noxious stimuli and promote positive auditory, tactile, gustatory, and olfactory experiences to optimize neurodevelopment for the complex task of feeding.

Validation of a Deep Learning System for the Full Automation of Bite and Meal Duration Analysis of Experimental Meal Videos.

Eating behavior can have an important effect on, and be correlated with, obesity and eating disorders. Eating behavior is usually estimated through self-reporting measures, despite their limitations in reliability, based on ease of collection and analysis. A better and widely used alternative is the objective analysis of eating during meals based on human annotations of in-meal behavioral events (e.g., bites). However, this methodology is time-consuming and often affected by human error, limiting its scalability and cost-effectiveness for large-scale research. To remedy the latter, a novel "Rapid Automatic Bite Detection" (RABiD) algorithm that extracts and processes skeletal features from videos was trained in a video meal dataset (59 individuals; 85 meals; three different foods) to automatically measure meal duration and bites. In these settings, RABiD achieved near perfect agreement between algorithmic and human annotations (Cohen's kappa κ = 0.894; F1-score: 0.948). Moreover, RABiD was used to analyze an independent eating behavior experiment (18 female participants; 45 meals; three different foods) and results showed excellent correlation between algorithmic and human annotations. The analyses revealed that, despite the changes in food (hash vs. meatballs), the total meal duration remained the same, while the number of bites were significantly reduced. Finally, a descriptive meal-progress analysis revealed that different types of food affect bite frequency, although overall bite patterns remain similar (the outcomes were the same for RABiD and manual). Subjects took bites more frequently at the beginning and the end of meals but were slower in-between. On a methodological level, RABiD offers a valid, fully automatic alternative to human meal-video annotations for the experimental analysis of human eating behavior, at a fraction of the cost and the required time, without any loss of information and data fidelity.

Feeding habits of the cockfish, Callorhinchus callorynchus (Holocephali: Callorhinchidae) from off northern Argentina

The feeding habits of Callorhinchus callorynchus were investigated in coastal waters off northern Argentina. The effect of body size, seasons and regions was evaluated on female diet composition using a multiple-hypothesis modelling approach. Callorhinchus callorynchus fed mainly on bivalves (55.61% PSIRI), followed by brachyuran crabs (10.62% PSIRI) and isopods (10.13% PSIRI). Callorhinchus callorynchus females showed changes in the diet composition with increasing body size and also between seasons and regions. Further, this species is able to consume larger bivalves as it grows. Trophic level was 3.15, characterizing it as a secondary consumer. We conclude that C. callorynchus showed a behavior of crushing hard prey, mainly on bivalves, brachyuran, gastropods and anomuran crabs. Females of this species shift their diet with increasing body size and in response to seasonal and regional changes in prey abundance or distribution.(AU)

RESUMEN Los hábitos alimentarios de Callorhinchus callorynchus fueron investigados en las aguas costeras del norte de Argentina. Se evaluó el efecto del tamaño del cuerpo, la temporada y la región sobre la composición de la dieta de las hembras mediante un enfoque de modelado de múltiples hipótesis. Callorhinchus callorynchus se alimentó principalmente de bivalvos (55,61% PSIRI), seguido de cangrejos brachyuras (10,62% PSIRI) y de isópodos (10,13% PSIRI). Las hembras de C. callorynchus presentaron cambios en la dieta con incremento del tamaño del cuerpo, la temporada y la región. Además, esta especie es capaz de consumir bivalvos de mayor tamaño a medida que incrementa el tamaño del cuerpo. El nivel trófico fue calculado en 3,15, caracterizando a esta especie como un consumidor secundario. Concluimos que C. callorynchus presentó un comportamiento de triturador de presas duras, principalmente bivalvos, cangrejos y gasterópodos. Las hembras de esta especie cambian su dieta con el incremento del tamaño del cuerpo y en respuesta a cambios temporales y regionales en la abundancia y distribución de sus presas.(AU)

Convergent responses of fish belonging to different feeding guilds to sewage pollution

This study aimed to evaluate if the presence of pollutants promotes changes in feeding habits of fish species from different trophic guilds: the detritivorous species, Hypostomus francisci, and the piscivorous, Hoplias intermedius. Both species were sampled at 12 sites (with different degrees of pollution) in the Rio das Velhas basin, which is heavily polluted by domestic and industrial sewage from the Metropolitan Region of Belo Horizonte (MRBH). Stable isotope analyses of carbon (δ13C) and nitrogen (δ15N) of fish tissue and the main food resources were performed. Fishes from both trophic guilds altered their diets in degraded environments, but the detritivorous species showed greater trophic plasticity. The isotopic niche of both trophic guilds was broadest in unpolluted sites and more δ15N enriched in polluted regions. The detritivorous species presented high niche-breadth in unpolluted sites, probably due to the greater variety of resources consumed. In addition, the δ15N of the detritivorous was more enriched than the piscivorous species in polluted sites. In conclusion, fishes from both trophic guilds presented similar isotopic responses to environmental pollution. However, the detritivorous species was more sensitive to these alterations and therefore, is likely a better indicator of environmental condition than the piscivorous.(AU)

Este estudo teve como objetivo avaliar se a presença de poluentes promove mudanças nos hábitos alimentares de espécies de peixes de diferentes guildas tróficas: a espécie detritívora, Hypostomus francisci, e a piscívora, Hoplias intermedius. Ambas espécies foram amostradas em 12 locais (com diferentes níveis de poluição) na bacia do Rio das Velhas, que é altamente poluída por esgoto doméstico e industrial da Região Metropolitana de Belo Horizonte (RMBH). Foram realizadas análises de isótopos estáveis de carbono (δ13C) e nitrogênio (δ15N) dos tecidos dos peixes e dos principais recursos alimentares. Espécies de ambas guildas tróficas alteraram suas dietas em ambientes degradados, mas a espécie detritívora apresentou maior plasticidade trófica. O nicho isotópico de ambas as espécies foi mais amplo em locais menos perturbados e mais enriquecido em δ15N em regiões poluídas. A espécie detritívora apresentou grande amplitude em seu nicho isotópico em locais menos perturbados, provavelmente devido à maior variedade de recursos consumidos. Além disso, o δ15N da espécie detritívora foi mais enriquecido que a espécie piscívora em locais poluídos. Em conclusão, ambas as espécies apresentaram respostas isotópicas semelhantes à poluição ambiental. No entanto, a espécie detritívora foi mais sensível a essas alterações e, portanto, é provavelmente uma melhor indicadora de condição ambiental do que a espécie piscívora.(AU)

Food consumption and depression among Brazilian adults: results from the Brazilian National Health Survey, 2013 / Consumo alimentar e depressão entre adultos brasileiros: resultados da Pesquisa Nacional de Saúde, 2013 / Consumo alimentario y depresión entre adultos brasileños: resultados de la Encuesta Nacional de Salud, 2013

Abstract: Our study aimed to evaluate the association between food consumption and depression. We used data from the Brazilian National Health Survey; a cross-sectional study carried out in 2013 among 46,785 Brazilian adults. The exposures were regular consumption (≥ 5 times/week) of the markers of healthy (beans, vegetables, fruits, and natural fruit juices) and unhealthy food (sugar sweetened beverages; sweets and the substitution of lunch or dinner for snacks); and a nutritional score elaborated by combining the frequency of consumption of markers of healthy and unhealthy food, the higher the value, the better the diet. The outcome was depression, assessed through the PHQ-9 questionnaire answered by the participants. Those with PHQ-9 scores greater than or equal to 10 were classified as presenting depression. We performed logistic regression models adjusted for potential confounders. Regular consumption of sweets (OR = 1.53; 95%CI: 1.33-1.76) and regular replacement of meals for snacks (OR = 1.52; 95%CI: 1.21-1.90) were positively associated with depression. Regular consumption of sugar sweetened beverages was positively associated with depression among women (OR = 1.27; 95%CI: 1.10-1.48). Regular consumption of beans was negatively associated with depression (OR = 0.74; 95%CI: 0.65-0.84), consistent for both sexes. Comparing the top quintile of the nutritional score (healthier diet) to the bottom quintile (less healthy) we found a negative association with depression (OR = 0.63; 95%CI: 0.52-0.75). Our results add evidence on a possible role of food consumption in depression; future longitudinal studies should explore the mechanisms of these associations.

Resumo: O estudo teve como objetivo avaliar a associação entre consumo alimentar e depressão. Utilizamos dados da Pesquisa Nacional de Saúde, um inquérito transversal realizado em 2013 em uma amostra de 46.785 adultos brasileiros. As variáveis de exposição foram consumo regular (≥ 5 vezes/semana) de marcadores de alimentos saudáveis (feijão, verduras e hortaliças, frutas e sucos naturais) e não saudáveis (bebidas açucaradas, doces e substituição de almoço ou jantar por lanches); e uma pontuação nutricional elaborada pela combinação da frequência de consumo de marcadores de alimentos saudáveis e não saudáveis, em que valores mais altos indicam melhor qualidade da alimentação. A variável dependente foi depressão, avaliada pelo questionário PHQ-9, respondido pelos participantes. Aqueles com PHQ-9 igual ou maior que 10 foram classificados como apresentando depressão. Foram construídos modelos de regressão logística, ajustados para potenciais fatores de confusão. O consumo regular de doces (OR = 1,53; IC95%: 1,33-1,76) e substituição regular de refeições por lanches (OR = 1,52; IC95%: 1,21-1,90) mostraram associação positiva com depressão. O consumo regular de bebidas açucaradas mostrou associação positiva com depressão entre mulheres (OR = 1,27; IC95%: 1,10-1,48). O consumo regular de feijão mostrou associação negativa com depressão (OR = 0,74; IC95%: 0,65-0,84) em ambos os sexos. A comparação do quintil mais alto de pontuação nutricional (dieta mais saudável) com o quintil mais baixo (menos saudável) mostrou associação negativa com depressão (OR = 0,63; IC95%: 0,52-0,75). Os resultados fornecem evidências sobre o papel potencial do consumo alimentar na depressão. No futuro, estudos longitudinais devem explorar os mecanismos dessas associações.

Resumen: El objetivo de nuestro estudio fue evaluar la asociación entre el consumo de comida y la depresión. Usamos datos de la Encuesta Nacional de Salud para llevar a cabo un estudio transversal en 2013 entre 46.785 brasileños adultos. Las exposiciones fueron: consumo regular (≥ 5 veces/semana) de los marcadores de comida saludable (frijoles, vegetables, frutas, y zumos de fruta natural) y alimentos no saludables (bebidas azucaradas; dulces y la sustitución del almuerzo o cena por aperitivos); y un marcador nutricional creado, combinando la frecuencia de consumo de los marcadores de comida saludable y no saludable, cuanto mayor era el valor, mejor era la dieta. El resultado fue depresión, evaluado a través del cuestionario PHQ-9, respondido por parte de los participantes. Aquellos con puntuaciones PHQ-9 mayores o iguales a 10 fueron clasificados como depresivos. Realizamos una regresión logística con modelos ajustados a factores potenciales de confusión. El consumo regular de dulces (OR = 1,53; IC95%: 1,33-1,76) y la sustitución regular de comidas por aperitivos (OR = 1,52; IC95%: 1,21-1,90) estuvieron positivamente asociados con la depresión. El consumo regular de bebidas azucaradas estuvo positivamente asociado a la depresión entre mujeres (OR = 1,27; IC95%: 1,10-1,48). El consumo regular de frijoles estuvo negativamente asociado a la depresión (OR = 0,74; IC95%: 0,65-0,84), consistente para ambos sexos. Comparando la puntuación nutricional más alta del quintil (la dieta más sana) con la más baja del quintil (la menos sana) encontramos una asociación negativa con la depresión (OR = 0,63; IC95%: 0,52-0,75). Nuestros resultados añaden evidencias sobre el posible rol del consumo de comida en la depresión; estudios longitudinales futuros deberían explorar los mecanismos de estas asociaciones.

Psychometric properties of the eating loss of control scale among postbariatric patients.

BACKGROUND: Assessing the complexities of eating behaviors in patients who undergo bariatric surgery is challenging. The Eating Loss of Control Scale (ELOCS), a measure of loss-of-control (LOC) eating, has not yet been evaluated psychometrically among bariatric surgery patients. OBJECTIVE: This study presents a psychometric examination of the ELOCS in postoperative bariatric surgery patients. SETTING: Academic medical center in the United States. METHODS: One hundred seventy-one postbariatric treatment-seeking adults (82.5% female, 52.4% white) with LOC eating completed the ELOCS and measures assessing eating psychopathology and mood. Confirmatory factor analysis (CFA) was used to test fit for a 1-factor solution. Exploratory factor analysis (EFA) examined alternative factor structures. RESULTS: CFA revealed poor fit for a 1-factor structure (χ2 = 220.375, degrees of freedom = 135, P < .001, comparative fit index = .917, Tucker-Lewis index = .906, root mean square error of approximation = .067). EFA data suggested an alternative factor solution (χ2 = 157.76, degrees of freedom = 118, P = .009, comparative fit index = .965, Tucker-Lewis index = .955, root mean square error of approximation = .047). Factor 1 (α = .88) reflected behavioral aspects and factor 2 (α = .92) reflected cognitive/emotional aspects of LOC eating. Bivariate correlations with measures of eating and other psychopathology suggested good construct validity for factors. CONCLUSIONS: Findings suggest possible differences in the construct validity of the ELOCS among postbariatric patients. The 1-factor solution previously supported in clinical and nonclinical groups demonstrated poor fit. EFA revealed a possible alternative 2-factor solution that aligns with emerging literature, suggesting that LOC eating presents differently in postbariatric patients. Researchers interested in LOC eating among bariatric patients should consider use of the ELOCS and testing the proposed alternative factor structure.

Association of Assisted Reproductive Techniques with Infant Feeding Practices: A Community-Based Study in China.

Background: With births generated with assisted reproductive techniques (ARTs) increasingly, the effect of ARTs on infant feeding behaviors is an essential topic to explore. However, limited literature focused on this topic. The objective of this study is to examine the effect of ARTs on infant feeding behaviors. Materials and Methods: Participants, including 41 mothers who conceived with ARTs and 935 conceived spontaneously, were drawn from a prospective birth cohort between January 2015 and December 2015. The participants were followed up at 1, 3, 6, 8, and 12 months postpartum at their residences through a face-to-face interview. Feeding behaviors, including breastfeeding initiation, partial/exclusive breastfeeding duration and formula introduction were assessed using World Health Organization-recommended definitions. Cox and logistic regression models were applied to examine the association of assisted conception with feeding behaviors. Results: Breastfeeding initiation rates were comparable between women who conceived with and without ARTs (70.7% versus 76.0%). Breastfeeding duration and formula introduction were significantly shorter and earlier in assisted conceptions in univariate analyses at 6 months postpartum [crude hazard ratios (HRs), 95% confidence intervals (CIs) 2.02 (1.03-3.84), and 1.63 (1.09-2.44)]. However, after controlling for covariates, assisted conception was only associated with shorter breastfeeding duration at 6 months postpartum [adjusted HR 1.99, 95% CI 1.05-3.80], no significant differences were found in infant feeding outcomes at 12 months postpartum among women with ART conception versus general conception. Mothers who conceived through ARTs with cesarean deliveries were at the highest risks of shorter breastfeeding duration and earlier formula introduction than mothers who conceived spontaneously with vaginal deliveries. Conclusions: Mothers who conceive through ARTs are associated with shorter breastfeeding durations for the first 6 months, compare to mothers who conceive spontaneously. Furthermore, cesarean delivery has a joint effect with the treatment of ARTs on promoting the development of poor feeding behaviors.

Consumption of minimally processed and ultra-processed foods among students from public and private schools / Consumo de alimentos minimamente processados e ultraprocessados entre escolares das redes pública e privada

ABSTRACT Objective: To compare and analyze the consumption of minimally processed and ultra-processed foods among students from public and private schools. Methods: Study conducted in Uberlândia, MG, with fifth-grade students from three private and six public schools, selected by stratified cluster sampling. We collected data on food consumption using the 24-hour recall. Foods were classified into four groups (G) according to extent and purpose of processing: fresh/minimally processed foods (G1) culinary ingredients (G2), processed foods (G3), and ultra-processed foods (G4). Total energy intake (kcal) of each group, amount of sugar (g), sodium (mg), and fiber (g) were quantified and compared according to administrative affiliation (private or public). Results: Percentage of total energy intake was: G1 - 52%; G2 - 12%; G3 - 5%; e G4 - 31%. Energy intake from G1 (53 vs. 47%), G2 (12 vs. 9%), and G3 (6.0 vs. 0.1%), and amount of sodium (3,293 vs. 2,724 mg) and fiber (23 vs. 18 g) were higher among students from public schools. Energy intake from G4 (36 vs. 28%) and amount of sugar (20 vs. 14%) were higher among students from private schools. The consumption of foods from G1 in the school environment was higher among students from public schools (40 vs. 9%). Conclusions: Foods from G1 represent the highest percentage of total energy intake, while those from G4 constitute a third of calories consumed. Processed juice, sandwich cookie, processed cake, and breakfast cereals are more frequent among private school students; snacks and juice powder are more common for students from public schools.

RESUMO Objetivo: Comparar e analisar o consumo de alimentos minimamente processados e ultraprocessados entre escolares das redes pública e privada. Métodos: Estudo realizado em Uberlândia, MG, com escolares do quinto ano do ensino fundamental em nove escolas (três privadas e seis públicas), selecionados por amostragem estratificada por conglomerado. O consumo alimentar foi analisado utilizando recordatório de 24 horas. Os alimentos foram classificados segundo extensão e propósito do seu processamento em quatro grupos (G): alimentos in natura/minimamente processados (G1), ingredientes culinários (G2), alimentos processados (G3) e ultraprocessados (G4). Os valores energéticos totais (kcal) provenientes de cada grupo, quantidade de açúcar (g), sódio (mg) e fibras (g) foram quantificados e comparados segundo dependência administrativa. Resultados: O consumo de energia foi: G1, 52%; G2, 12%; G3, 5%; e G4, 31%. Os valores energéticos provenientes de G1 (53 vs. 47%), G2 (12 vs. 9%) e G3 (6,0 vs. 0,1%), a quantidade de sódio (3.293 vs. 2.724 mg) e a de fibras (23 vs. 18 g) foram superiores em escolares da rede pública. O valor percentual energético do G4 (36 vs. 28%) e a quantidade de açúcar (20 vs. 14%) foram superiores em escolares da rede privada. O consumo do G1 na escola foi superior nos escolares da rede pública (40 vs. 9%). Conclusões: Alimentos do G1 representam o maior percentual do valor energético total e do G4, um terço das calorias ingeridas. Suco pronto, biscoito recheado, bolo industrializado, cereais matinais são mais frequentes em escolares da rede privada e salgadinhos e suco em pó nos da rede pública.

CONSUMPTION OF MINIMALLY PROCESSED AND ULTRA-PROCESSED FOODS AMONG STUDENTS FROM PUBLIC AND PRIVATE SCHOOLS.

OBJECTIVE: To compare and analyze the consumption of minimally processed and ultra-processed foods among students from public and private schools. METHODS: Study conducted in Uberlândia, MG, with fifth-grade students from three private and six public schools, selected by stratified cluster sampling. We collected data on food consumption using the 24-hour recall. Foods were classified into four groups (G) according to extent and purpose of processing: fresh/minimally processed foods (G1) culinary ingredients (G2), processed foods (G3), and ultra-processed foods (G4). Total energy intake (kcal) of each group, amount of sugar (g), sodium (mg), and fiber (g) were quantified and compared according to administrative affiliation (private or public). RESULTS: Percentage of total energy intake was: G1 - 52%; G2 - 12%; G3 - 5%; e G4 - 31%. Energy intake from G1 (53 vs. 47%), G2 (12 vs. 9%), and G3 (6.0 vs. 0.1%), and amount of sodium (3,293 vs. 2,724 mg) and fiber (23 vs. 18 g) were higher among students from public schools. Energy intake from G4 (36 vs. 28%) and amount of sugar (20 vs. 14%) were higher among students from private schools. The consumption of foods from G1 in the school environment was higher among students from public schools (40 vs. 9%). CONCLUSIONS: Foods from G1 represent the highest percentage of total energy intake, while those from G4 constitute a third of calories consumed. Processed juice, sandwich cookie, processed cake, and breakfast cereals are more frequent among private school students; snacks and juice powder are more common for students from public schools.

Food consumption and depression among Brazilian adults: results from the Brazilian National Health Survey, 2013.

Our study aimed to evaluate the association between food consumption and depression. We used data from the Brazilian National Health Survey; a cross-sectional study carried out in 2013 among 46,785 Brazilian adults. The exposures were regular consumption (≥ 5 times/week) of the markers of healthy (beans, vegetables, fruits, and natural fruit juices) and unhealthy food (sugar sweetened beverages; sweets and the substitution of lunch or dinner for snacks); and a nutritional score elaborated by combining the frequency of consumption of markers of healthy and unhealthy food, the higher the value, the better the diet. The outcome was depression, assessed through the PHQ-9 questionnaire answered by the participants. Those with PHQ-9 scores greater than or equal to 10 were classified as presenting depression. We performed logistic regression models adjusted for potential confounders. Regular consumption of sweets (OR = 1.53; 95%CI: 1.33-1.76) and regular replacement of meals for snacks (OR = 1.52; 95%CI: 1.21-1.90) were positively associated with depression. Regular consumption of sugar sweetened beverages was positively associated with depression among women (OR = 1.27; 95%CI: 1.10-1.48). Regular consumption of beans was negatively associated with depression (OR = 0.74; 95%CI: 0.65-0.84), consistent for both sexes. Comparing the top quintile of the nutritional score (healthier diet) to the bottom quintile (less healthy) we found a negative association with depression (OR = 0.63; 95%CI: 0.52-0.75). Our results add evidence on a possible role of food consumption in depression; future longitudinal studies should explore the mechanisms of these associations.

A meta-analysis of early oral refeeding and quickly increased diet for patients with mild acute pancreatitis.

BACKGROUND/AIM: The objective of the study is to clarify whether early oral refeeding (EORF) and quickly increasing diet (QID) are of benefit to patients with mild acute pancreatitis compared with a traditional oral refeeding strategy. MATERIALS AND METHODS: Studies were searched in PubMed, Cochrane library, ScienceDirect, SpringerLink, China Biology Medicine disc and Embase. A meta-analysis was then performed, using relapse of abdominal pain, nausea/vomiting, and length of hospital stay (LOHS) as the evaluation indices. RESULTS: Eight trials met the inclusion criteria. For the oral refeeding time group, EORF could significantly decrease the LOHS (mean deviation [MD] -1.97; 95% confidence interval (CI) -3.32 to -0.62;P = 0.004), and there was no significant difference for relapse of abdominal pain (relative risk [RR] 1.17; 95% CI 0.69-2.00;P = 0.56) or nausea/vomiting (RR 1.30; 95% CI 0.19-8.82;P = 0.79) when compared with conventional oral refeeding. For the oral refeeding material group, there was no significant difference for relapse of abdominal pain (RR 0.86; 95% CI 0.53-1.40;P = 0.54), nausea/vomiting (risk difference -0.01; 95% CI -0.19-0.18;P = 0.94), or LOHS (MD -0.88; 95% CI -2.24-0.48;P = 0.20) between the QID and stepwise increasing diet groups. CONCLUSION: Pure EORF or QID caused no damage to patients with mild acute pancreatitis, and EORF could significantly decrease the LOHS.

Profile Resemblance in Health-Related Markers: The Portuguese Sibling Study on Growth, Fitness, Lifestyle, and Health.

The co-occurrence of health-related markers and their associations with individual, family, and environmental characteristics have not yet been widely explored in siblings. We aimed to identify multivariate profiles of health-related markers, analyze their associations with biological, sociodemographic, and built environment characteristics, and estimate sibling resemblance in these profiles. The sample includes 736 biological siblings aged 9⁻20 years. Body fat was measured with a portable bioelectrical impedance scale; biological maturation was assessed with the maturity offset; handgrip strength, standing long jump, one-mile run, and shuttle run were used to mark physical fitness. Health behaviors, sociodemographic, and built environmental characteristics were recorded by questionnaire. Latent profile analysis and multilevel logistic regression models were used; sibling resemblance was estimated with the intraclass correlation (ρ). Two multivariate profiles emerged: "P1 = fit, lower fat and poorer diet" (86.7%) and "P2 = higher fat and lower fit, but better diet" (13.3%). Siblings whose fathers were less qualified in their occupation were more likely to belong to P2 (OR = 1.24, p = 0.04); those whose fathers with Grade 12 and university level education were more likely to fit in P2 compared to peers living with fathers having an educational level below Grade 12 (OR = 3.18, p = 0.03, and OR = 6.40, p = 0.02, Grade 12 and university level, respectively). A moderate sibling profile resemblance was found (0.46 ≤ ρ ≤ 0.55). In conclusion, youth health-related markers present substantial differences linked with their body composition, physical fitness and unhealthy diet. Furthermore, only father socio-demographic characteristics were associated with profile membership. Sibling´s profile resemblance mirrors the effects of genetics and shared characteristics.
