Estilos de vida relacionados con la salud en estudiantes de Enfermería / Lifestyles health related in Nursing students

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.

Introducción: Los hábitos de vida adquiridos y el mediouniversitario se convierten en importantes factores que influencian los comportamiento relacionados con la actividad física y la alimentación en los jóvenes.Objetivo: identificar los hábitos relacionados con las prácticas alimentarias y de actividad física en adultos jóvenes universitarios en el caribe colombiano.Materiales y Métodos: Estudio descriptivo transversal,en estudiantes universitarios de cuatro ciudades de la regióncaribe colombiana. Se aplicó un cuestionario autoadministrado, que indagaba sobre características sociodemográficas yacadémicas, entre tanto para cuantificar los estilos de vida seempleó el cuestionario PEVP-II. Para el análisis de esta publicación se observó la información correspondiente a las dimensiones nutrición y actividad física.Resultados: El 61,26% de los participantes fueron mujeres, el rango de edad con mayor predominio fue entre 15 y26 años, con mayor representación de estudiantes de lasciencias de la salud, de estrato socioeconómico bajo. El sexoguarda relación con los hábitos nutricionales asociados a mayor consumo de carbohidratos, azúcares, así como escasoconsumo de frutas y vegetales. Se observó relación entre elsexo y la escasa práctica de actividad física. Conclusión: la falta de hábitos saludables en la juventudestá dada por las conductas aprehendidas e influenciadas porel entorno en el cual crece y se desarrolla el ser humano enetapas tempranas de la vida. Es importante pensar las formasen que el ámbito universitario podría influir de manera positiva en mejores actitudes y comportamientos relacionadoscon el bienestar general del joven.(AU)

Introduction: Life habits have an important influence onthe environment in which the young person develops. Theuniversity environment becomes an environment thatinfluences behaviors related to physical activity and food.Objective: to identify habits related to eating and physicalactivity practices in young university adults in the Colombian Caribbean. Materials and Methods: Cross-sectional descriptivestudy in university students from four cities in the ColombianCaribbean region. A self-administered questionnaire wasapplied, which inquired about sociodemographic andacademic characteristics, while the PEVP-II questionnaire wasused to quantify lifestyles. For the analysis of this publication,the information corresponding to the dimensions of nutritionand physical activity was observed.Results: 61.26% of the participants were women, therange of age with the highest predominance was between 15and 26 years, with greater representation of of the healthsciences, of low socioeconomic stratum. Sex is related to thenutritional habits associated with higher consumption ofcarbohydrates, sugars, as well as low consumption of fruitsand vegetables. A relationship was observed between sex andthe low practice of physical activity. Conclusion: the lack of healthy habits in youth is given bythe behaviors apprehended and influenced by theenvironment in which the human being grows and developsin early stages of life. It is important to think about the waysin which the university environment could positively influencebetter attitudes and behaviors related to the general well-being of the young person.(AU)

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).

¿Es más cara la alimentación saludable? / Is healthy food more expensive?

INTRODUCCIÓN: En ocasiones se ha relacionado el precio de los alimentos con su calidad nutritiva, de forma que los alimentos de menor valor nutritivo resultan los más baratos. Así, la alta disponibilidad de alimentos de bajo coste, podría ser un factor a considerar entre los responsables del aumento de la frecuencia de la obesidad que se observa. OBJETIVO: Realizar una comparativa económica entre el coste de una dieta saludable y otra no saludable. MÉTODO: Estudio descriptivo, transversal. Muestra constituida por 15 sujetos entre 18 y 57 años. Se recogieron los hábitos alimentarios de 3 días, mediante recordatorio de 24 horas y diario dietético. El criterio de dietas saludables o no, se estableció en función de la Guía Alimentaria SENC de diciembre de 2016. Se realizó un cálculo económico del coste diario de la cesta de la compra, un análisis de la media de 3 días del coste de la cesta de la compra y el coste de las comidas realizadas fuera del hogar. Se compararon los costes de la cesta de la compra de quienes tenían una Dieta Saludable y No Saludable. También se tuvo en cuenta en el estudio el IMC de los sujetos. RESULTADOS: Los resultados obtenidos confirman que es más económica una dieta saludable que una no saludable, y que el IMC no tiene una correlación directa y exclusiva con el hecho de seguir una dieta de mayor o menor calidad nutricional. CONCLUSIONES: Si consideramos que el factor económico no es uno de los factores más importante en el hecho de llevar unas pautas nutricionales saludables, sería interesante un estudio posterior con una muestra más amplia y una actuación educativo-nutricional para dar herramientas a la población que les posibilite unas elecciones más adecuadas de alimentos y mayor implicación personal en tiempo, conocimiento de técnicas, etc., más allá del aspecto puramente económico

INTRODUCTION: Occasionally, the price of food has been linked to its nutritional quality so that foods with lower nutritional value are the cheapest. Thus, the high availability of low-priced food could be a factor to consider among the ones responsible for the increased frequency of obesity that is now been observed. OBJECTIVE: The main objective of this study was to make an economic comparison between the cost of healthy eating vs unhealthy eating. METHODS: A cross-sectional descriptive study. The sample was made up of 15 individuals aged 18-57. Eating habits were collected for 3 days via 24- hour dietary recall and diet diary. The criteria for a healthy or unhealthy diet was stablished according to the SENC Food Guidance- December 2016. Daily cost of shopping basket, analysis of the average shopping basket for three days and the cost of food eating outside were made. The cost of shopping basket was compared between healthy and unhealthy eaters. The BMI was also considered in this study. RESULTS: The results obtained confirm that a healthy diet is cheaper than an unhealthy one and that there is not direct and exclusive correlation between the BMI and healthy or unhealthy eating. CONCLUSIONS: If we consider that the economic factor is the most important one regarding healthy eating patterns, further study based on a wider simple and an educational-nutritional intervention would be interesting in order to provide individuals with tools to make possible the most adequate election of the food and a greater personal involvement in time, technical knowledge, etc. beyond the economic aspect

Valoración del documento de consenso sobre alimentación en centros educativos para evaluar menús escolares / Assessment of the consensus document on food in educational centres to evaluate school menus

OBJETIVO: Explorar la aplicabilidad del Documento de Consenso sobre Alimentación en los Centros Educativos (DCSECE) para evaluar la adecuación de los menús escolares a las recomendaciones de una alimentación saludable. MÉTODO: Estudio transversal en el que se analizaron menús mensuales de 28 centros de educación infantil y primaria de Andalucía y Canarias. Los datos se extrajeron mediante un protocolo ad hoc basado en las recomendaciones del DCSECE, las cuales se dividieron en categorías y subcategorías de alimentos. Se estudió la oferta semanal de cada una de las categorías y subcategorías de alimentos y se comparó con las recomendaciones del DCSECE. RESULTADOS: La mayoría de los centros presentó una oferta superior a la recomendación para la categoría de hortalizas y verduras, otras guarniciones y otros postres; inferior para la de arroz, pasta, elaborados y ensaladas; y ajustada para la de legumbres, carnes, pescado y huevos. Por subcategorías, se observó el predominio de vegetales cocidos en la categoría de hortalizas y verduras, en perjuicio de las ensaladas, y una oferta elevada de carnes procesadas en la categoría de carnes. CONCLUSIONES: El DCSECE puede ser un instrumento útil para evaluar la oferta alimentaria en los menús escolares, pero precisa una mayor especificidad en las recomendaciones para identificar la adecuación de los menús a una alimentación saludable

OBJECTIVE: To explore the applicability of the Consensus Document on School Food Programmes in Educational Centres (DCSECE) to evaluate the adaptation of school menus to healthy eating recommendations. METHOD: Transversal study that analyzes monthly school menus from 28 early-childhood education and primary education centres in Andalusia and Canary Islands (Spain). Data were collected using an ad-hoc protocol based on the DCSECE recommendations and divided into food categories and subcategories. We studied the weekly menu offering of each of the foods by category and subcategory and compared them to the DCSECE recommendations. RESULTS: The majority of the schools offered better meals than as specified by the recommendations, in terms of vegetables, other garnishes and other deserts. They offered poorer quality meals in the categories of rice, pasta, prepared foods and salads, and had an equivalent offering in terms of pulses, meats, fish and eggs. By subcategory, we observed the predominance of cooked vegetables in the vegetable category as compared to salads, and the predominance of processed meats in the meats category. CONCLUSIONS: The DCSECE could be a useful instrument for evaluating the nutritional offering of school menus. However, there is a need for greater specificity in the recommendations, in order to identify whether these menus adhere to healthy eating recommendations

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.

Economía del comportamiento para mejorar estilos de vida y reducir factores de riesgo / Behavioral economics to improve lifestyle choices and to reduce risk factors

Una parte importante de la morbimortalidad se debe a hábitos de vida y factores de riesgo modificables. Una estrategia prometedora para promover el cambio de tales factores pasa por la aplicación de intervenciones de salud pública basadas en la economía del comportamiento, rama del conocimiento que combina principios psicológicos y económicos. Este artículo se centra en un tipo de intervención conocida como nudge (traducida habitualmente como «empujón» o «acicate»), que modifica la conducta sin restringir la capacidad de elección de las personas. Se analizan las diferentes propiedades que caracterizan a los nudges y diversos ámbitos en los que se han aplicado con éxito: vacunación, alimentación, actividad física, cesación tabáquica y prescripción de medicamentos. En conclusión, la economía del comportamiento y los nudges tienen un gran potencial para su aplicación en la esfera de la salud pública en España

A large part of morbimortality is caused by lifestyle habits and modifiable risk factors. A promising strategy to promote the change of such factors is the implementation of public health interventions based on behavioral economics, a discipline that combines psychological and economic principles. In the present article, we focus on a type of intervention known as "nudge" (that has been translated into Spanish as empujón or acicate), that changes behaviour without limiting the individual's choice. We analyze the properties that characterize nudges, and several areas in which they have been successfully implemented: vaccination, nutrition, physical activity, smoking cessation and drug prescription. We conclude that behavioural economics and nudges have great potential for their implementation in the public health sphere in Spain

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.

Evaluación del estado nutricional y comportamientos de salud en escolares de San Miguel de Tucumán, Argentina / Evaluation of nutritional status and health behaviors in schoolchildren from San Miguel de Tucumán, Argentina

INTRODUCCIÓN: La infancia y adolescencia son etapas cruciales de la vida en los cuales comienzan a formarse y adquirirse los hábitos que se van a sostener en el desarrollo hacia la adultez. OBJETIVOS: Determinar el estado nutricional y comportamientos de salud de los alumnos en escuelas y jardines municipales de San Miguel de Tucumán. MÉTODOS: Se realizó un estudio descriptivo, de corte transversal. La muestra estuvo conformada por escolares de 3 a 18 años de edad de ambos sexos (1239). Las variables estudiadas fueron edad, sexo, hábitos alimentarios, sedentarismo, peso, talla e índice de masa corporal. Se pesaron y midieron a los alumnos y los datos fueron tomados a partir de una encuesta estructurada. En el nivel inicial y primario se realizó una entrevista personal, los niños menores de 6 años fueron encuestados junto a sus padres o cuidadores, quienes colaboraron en las respuestas. En el nivel secundario el cuestionario fue autoadministrado. Se solicitó autorización a los alumnos más grandes y en el caso de menores de edad se pidió consentimiento informado a los padres. RESULTADOS: La prevalencia de sobrepeso y obesidad fue del 25,6 % y el 22,2 % respectivamente. Durante el último mes el 85,6 % de los estudiantes consumió 1 o más veces al día bebidas azucaradas, el 19,8% consumió verduras en almuerzo y cena, el 57,9% incluyó menos de dos frutas al día. El 73% consumió menos de 3 porciones al día de lácteos y el 14% incluyó 8 vasos diarios de agua. CONCLUSIONES: Se observó sedentarismo, exceso de peso y hábitos alimentarios inadecuados en relación a las recomendaciones de las nuevas "Guías Alimentarias para la población Argentina", lo que puede llevar a la aparición de Enfermedades Crónicas no Transmisibles de manera más acelerada

INTRODUCTION: Childhood and adolescence are crucial stages of life in which the habits that will be sustained in the development towards adulthood begin to form and acquire. OBJECTIVES: To determine the nutritional status and health behaviors of students in schools and municipal gardens of San Miguel de Tucumán. METHODS: A descriptive, cross-sectional study was carried out. The sample was made up of schoolchildren from 3 to 18 years of age of both sexes (1239). The variables studied were age, sex, eating habits, sedentary lifestyle, weight, height, and body mass index. The students were weighed and measured and the data was taken from a structured survey. At the initial and primary level, a personal interview was carried out. Children under 6 years of age were surveyed together with their parents or caregivers, who collaborated in the responses. At the secondary level, the questionnaire was selfadministered. Authorization was requested from older students and in the case of minors, informed consent was requested from parents. RESULTS: The prevalence of overweight and obesity was 25.6% and 22.2% respectively. During the last month 85.6% of the students consumed sugary drinks 1 or more times a day, 19.8% consumed vegetables at lunch and dinner, 57.9% included less than two fruits a day. 73% consumed less than 3 servings a day of dairy and 14% included 8 glasses of water daily. CONCLUSIONS: Sedentary lifestyle, excess weight and inadequate eating habits were observed in relation to the recommendations of the new "Dietary Guidelines for the Argentine population", which can lead to the appearance of Chronic Non-Communicable Diseases more rapidly. This information is useful for knowing the current situation of municipal schools and executing health promotion policies in the school environment
