    The role of breakfast as an essential part of an healthy diet has been only recently promoted even if breakfast practices were known since the Middle Age. The growing scientific evidences on this topic are extremely sector-based nevertheless breakfast could be regarded from different point of views and from different expertises. This approach, that take into account history, sociology, anthropology, medicine, psychology and pedagogy, is useful to better understand the value of this meal in our culture. The aim of this paper was to analyse breakfast-related issues based on a multidisciplinary approach with input by specialists from different fields of learning. Breakfast is now recommended as part of a diet because it is associated with healthier macro- and micronutrient intakes, body mass index and lifestyle. Moreover recent studies showed that breakfast improves cognitive function, intuitive perception and academic performance. Research demonstrates the importance of providing breakfast not only to children but in adults and elderly too. Although the important role breakfast plays in maintaining the health, epidemiological data from industrialised countries reveal that many individuals either eat a nutritionally unhealthy breakfast or skip it completely. The historical, bio-psychological and educational value of breakfast in our culture is extremely important and should be recognized and stressed by the scientific community. Efforts should be done to promote this practice for the individual health and well-being.

    OBJECTIVE: To investigate (i) associations between adolescents' frequency of breakfast and family functioning (close relations to parents, quality of family communication and family support) and (ii) if any observed associations between breakfast frequency and family functioning vary...... (n 3054) from a random sample of forty-one schools. RESULTS: Nearly one-quarter of the adolescents had low breakfast frequency. Low breakfast frequency was associated with low family functioning measured by three dimensions. The OR (95 % CI) of low breakfast frequency was 1·81 (1·40, 2......·33) for adolescents who reported no close relations to parents, 2·28 (1·61, 3·22) for adolescents who reported low level of quality of family communication and 2·09 (1·39, 3·15) for adolescents who reported low level of family support. Joint effect analyses suggested that the odds of low breakfast frequency among...

    From 1997 to 2000, Philip Morris implemented Project Sunrise. This paper discusses the impact of this project on national and Philip Morris's cigarette unit sales, public opinion about smoking and secondhand tobacco smoke, and national prevalence trends for tobacco use. A qualitative archival content analysis of Project Sunrise from 1997 to 2000, and a descriptive statistical analysis of cigarette unit sales and operating profits, acceptability of smoking and secondhand tobacco smoke, and national prevalence trends for tobacco use from 1996 to 2006. Qualitative data sources related to Project Sunrise found on WebCat, Pubmed.com, LexisNexis Academic and Philip Morris's website, and archived tobacco industry documents were analysed using NVivo Version 9.0. A descriptive statistical analysis of cigarette unit sales, public opinion about smoking and secondhand tobacco smoke, and national prevalence trends for tobacco use was undertaken. Project Sunrise was a high-level strategic corporate plan to maintain profits that included four possible scenarios resulting in seven interwoven strategies. However, national prevalence rates for tobacco use declined, sales of national and Philip Morris cigarettes declined, operating profits remained at substantially lower levels after 2000 from 2001 to 2006, and a large majority of Americans agreed that there were significant health dangers associated with smoking and secondhand tobacco smoke. The impact of Project Sunrise, including countering the anti-tobacco movement, was less than successful in the USA. Copyright © 2012 The Royal Society for Public Health. Published by Elsevier Ltd.

  7. Breakfast and performance.

    Cueto, S

    2001-12-01

    Evidence suggests that the effect of fasting on performance is not uniform, but it is dependent on the basal nutritional status of the subject. Breakfast consumption has a short-term effect in improving selected learning skills, especially work memory. School breakfast programmes have a positive effect on the nutritional status of children, on school attendance and probably on dropout rates. The effect of breakfast consumption on school performance depends on the interaction between the programme, student characteristics (malnutrition) and school organisation. Unless the school setting guarantees a minimum quality standard, the benefits of breakfast consumption will not be evident in performance in complex areas like language or maths.

    Smith, A P

    1998-09-01

    The objective of the present investigation was to study the relationship between breakfast consumption and subjective reports of mental health and health-related behaviours in a general population sample (126 subjects aged between 20 and 79 years). Individuals who consumed a cereal breakfast each day were less depressed, less emotionally distressed and had lower levels of perceived stress than those who did not eat breakfast each day. Those who consumed breakfast had a healthier lifestyle than the others in that they were less likely to be smokers, drank less alcohol and had a healthier diet. However, the relationship between cereal breakfast consumption and mental health did not reflect these differences in the smoking, alcohol consumption and diet. In conclusion, there is an association between breakfast consumption and well-being which cannot entirely be accounted for by differences in other aspects of diet or smoking and alcohol consumption. Further intervention studies are now needed to establish whether causal relationships and mechanisms underlie the associations seen in this study.

    The Sun Radio Interferometer Space Experiment (SunRISE) is a NASA Heliophysics Explorer Mission of Opportunity currently in Phase A. SunRISE is a constellation of spacecraft flying in a 10-km diameter formation and operating as the first imaging radio interferometer in space. The purpose of SunRISE is to reveal critical aspects of solar energetic particle (SEP) acceleration at coronal mass ejections (CMEs) and transport into space by making the first spatially resolved observations of coherent Type II and III radio bursts produced by electrons accelerated at CMEs or released from flares. SunRISE will focus on solar Decametric-Hectometric (DH, 0.1 space before major SEP events, but cannot be seen on Earth due to ionospheric absorption. This talk will describe SunRISE objectives and implementation. Presented on behalf of the entire SunRISE team.

  12. What Time Is Sunrise? Revisiting the Refraction Component of Sunrise/set Prediction Models

    Wilson, Teresa; Bartlett, Jennifer L.; Hilton, James Lindsay

    2017-01-01

    Algorithms that predict sunrise and sunset times currently have an error of one to four minutes at mid-latitudes (0° - 55° N/S) due to limitations in the atmospheric models they incorporate. At higher latitudes, slight changes in refraction can cause significant discrepancies, even including difficulties determining when the Sun appears to rise or set. While different components of refraction are known, how they affect predictions of sunrise/set has not yet been quantified. A better understanding of the contributions from temperature profile, pressure, humidity, and aerosols could significantly improve the standard prediction. We present a sunrise/set calculator that interchanges the refraction component by varying the refraction model. We then compare these predictions with data sets of observed rise/set times to create a better model. Sunrise/set times and meteorological data from multiple locations will be necessary for a thorough investigation of the problem. While there are a few data sets available, we will also begin collecting this data using smartphones as part of a citizen science project. The mobile application for this project will be available in the Google Play store. Data analysis will lead to more complete models that will provide more accurate rise/set times for the benefit of astronomers, navigators, and outdoorsmen everywhere.

    2015-06-01

    Full Text Available In recent years the provision of school breakfast has increased significantly in the UK. However, research examining the effectiveness of school breakfast is still within relative stages of infancy, and findings to date have been rather mixed. Moreover, previous evaluations of school breakfast schemes have been predominantly quantitative in their methodologies. Presently there are few qualitative studies examining the subjective perceptions and experiences of stakeholders, and thereby an absence of knowledge regarding the sociocultural impacts of school breakfast. The purpose of this study was to investigate the beliefs, views and attitudes, and breakfast consumption behaviors, among key stakeholders, served by a council-wide universal free school breakfast initiative, within the North West of England, UK. A sample of children, parents and school staff were recruited from three primary schools, participating in the universal free school breakfast scheme, to partake in semi-structured interviews and small focus groups. A Grounded Theory analysis of the data collected identified a theoretical model of breakfast behaviors, underpinned by the subjective perceptions and experiences of these key stakeholders. The model comprises of three domains relating to breakfast behaviors, and the internal and external factors that are perceived to influence breakfast behaviors, among children, parents and school staff. Findings were validated using triangulation methods, member checks and inter-rater reliability measures. In presenting this theoretically grounded model for breakfast behaviors, this paper provides a unique qualitative insight into the breakfast consumption behaviors and barriers to breakfast consumption, within a socioeconomically deprived community, participating in a universal free school breakfast intervention program.

    2018-05-01

    Full Text Available Breakfast is often referred to as the most important meal of the day and in recent years has been implicated in weight control, cardio-metabolic risk factors and cognitive performance although, at present, the literature remains inconclusive as to the precise health benefits of breakfast. There are extensive reports of breakfast’s contributions to daily food and nutrient intakes, as well as many studies that have compared daily food and nutrient intakes by breakfast consumers and skippers. However, significant variation exists in the definitions of breakfast and breakfast skippers, and in methods used to relate breakfast nutrient intakes to overall diet quality. The present review describes a novel and harmonised approach to the study of the nutritional impact of breakfast through The International Breakfast research Initiative involving national dietary survey data from Canada, Denmark, France, Spain, the UK and the USA. It is anticipated that the analysis of such data along harmonised lines, will allow the project to achieve its primary goal of exploring approaches to defining optimal breakfast food and nutrient intakes. Such data will be of value to public health nutrition policy-makers and food manufacturers and will also allow consistent messaging to help consumers to optimize food choices at breakfast.

    2017-01-01

    Smartphones, with their ever increasing capabilities, are becoming quite instrumental for data acquisition in a number of fields. Understanding refraction and how it affects what we see on the horizon is no exception. Current algorithms that predict sunrise and sunset times have an error of one to four minutes at mid-latitudes (0° - 55° N/S) due to limitations in the atmospheric models they incorporate. At higher latitudes, slight changes in refraction can cause significant discrepancies, even including difficulties determining when the Sun appears to rise or set. A thorough investigation of the problem requires a substantial data set of observed rise/set times and corresponding meteorological data from around the world, which is currently lacking. We have developed a mobile application so that this data can be taken using smartphones as part of a citizen science project. The app allows the viewer to submit a video of sunrise/set and attaches geographic location along with meteorological data taken from a local weather station. The project will help increase scientific awareness in the public by allowing members of the community to participate in the data-taking process, and give them a greater awareness of the scientific significance of phenomenon they witness every day. The data from the observations will lead to more complete rise/set models that will provide more accurate times to the benefit of astronomers, navigators, and outdoorsmen. The app will be available on the Google Play Store.

    In the SUNRISE-project, the unemployment benefit office refers long-term unemployed clients (25-49 years old) to medical and psychological specialists of an addiction clinic, if substance-related problems are suspected as an obstacle for job placement. The present study aims at characterizing these clients with respect to educational qualifications, vocational training, diagnosed addictive disorders, and other mental disorders. Of special interest is the temporal sequence of unemployment and addictive disorders. Officials referred clients to medical examination if substance abuse was suspected. The examination was based on Europ-ASI, diagnosis of mental disorders based on SCID-I and SCID-II. In 87 out of the first 100 examined persons, an addictive disorder was diagnosed, most frequently alcohol-related disorders, and often multiple addictive disorders. These 87 clients were on average 40 years old (SD 8.5), and mostly male (73 out of 87 clients). About one-third had very low school qualification, and 55.2% had not completed vocational training. An additional psychiatric diagnosis was made in 51.7%. Addictive disorders had commenced during adolescence or early adulthood in most cases. The longest duration of continuous employment was 3 years (median). In only a few cases (7.4%), the current period of unemployment had started before regular substance use. Many long-term unemployed clients examined here showed deficits in schooling and vocational training, early onset of regular substance use, and additional mental disorders. In most cases, the addictive disorder did not emerge as a consequence of unemployment, but had existed before. Programs combining the efforts of unemployment benefit offices and the healthcare system are needed for these clients to help them gain access to the regular job market. © Georg Thieme Verlag KG Stuttgart · New York.

    The USNO is responsible for providing information through its website on various types of natural phenomena, including times of sunrise and sunset for any given day and location. Alternative websites were explored to see what options are available in case the USNO can no longer support this on-line tool in the future. Websites with sunrise/sunset calculators were examined to see what algorithm they cited, if any. A large percentage of the websites took their calculations from three main sources (USNO, Meeus, and Schlyter). For ease of comparison, one website with an Application Programming Interface (API) for each algorithm was used to generate sunrise/sunset times for 2 dates per year for 24 years at latitudes from the equator to each pole along the prime meridian. Additionally, dates on which only one phenomenon was expected (first and last day of polar day and night) were tested to examine how each algorithm would perform for these extreme edge cases. At mid-latitudes, all of the algorithms agreed within 1 minute of each other but their predictions began to diverge as they approached the poles. Close to the poles, all three differed by more than a minute. While the algorithms diverged well before reaching the poles, Schlyter did so at much lower latitudes compared to the other two. In the edge cases, Schlyter and Meeus did not correctly document the missing sunrise/sunsets. Until a set of arctic or antarctic observations of sunrise and sunset times can be analyzed, we cannot ascertain which algorithm is the most accurate. However, the USNO algorithm handled cases of continuous day and night better than the others. There currently seems to be no better alternative to provide robust sunrise/set times than the USNO Complete Sun and Moon Data for One Day (http://aa.usno.navy.mil/data/docs/RS_OneDay.php).

  1. The two-loop sunrise integral and elliptic polylogarithms

    2016-07-01

    In this talk, we present a solution for the two-loop sunrise integral with arbitrary masses around two and four space-time dimensions in terms of a generalised elliptic version of the multiple polylogarithms. Furthermore we investigate the elliptic polylogarithms appearing in higher orders in the dimensional regularisation ε of the two-dimensional equal mass solution. Around two space-time dimensions the solution consists of a sum of three elliptic dilogarithms where the arguments have a nice geometric interpretation as intersection points of the integration region and an elliptic curve associated to the sunrise integral. Around four space-time dimensions the sunrise integral can be expressed with the ε{sup 0}- and ε{sup 1}-solution around two dimensions, mass derivatives thereof and simpler terms. Considering higher orders of the two-dimensional equal mass solution we find certain generalisations of the elliptic polylogarithms appearing in the ε{sup 0}- and ε{sup 1}-solutions around two and four space-time dimensions. We show that these higher order-solutions can be found by iterative integration within this class of functions.

    2016-05-01

    Breakfast is thought to be beneficial for cognitive and academic performance in school children. However, breakfast is the most frequently skipped meal, especially among adolescents. The aim of the current article was to systematically review the evidence from intervention studies for the effects of breakfast on cognitive performance in children and adolescents. The effects of breakfast were evaluated by cognitive domain and breakfast manipulation. A total of 45 studies reported in 43 articles were included in the review. Most studies considered the acute effect of a single breakfast (n = 34). The acute studies looked at breakfast compared with no breakfast (n = 24) and/or comparisons of breakfast type (n = 15). The effects of chronic school breakfast program interventions were evaluated in 11 studies. The findings suggest that breakfast consumption relative to fasting has a short-term (same morning) positive domain-specific effect on cognition. Tasks requiring attention, executive function, and memory were facilitated more reliably by breakfast consumption relative to fasting, with effects more apparent in undernourished children. Firm conclusions cannot be made about the acute effects of breakfast composition and the effects of chronic breakfast interventions because there are too few studies and these largely report inconsistent findings. This review also highlights methodologic limitations of the existing research. These include a lack of research on adolescents, few naturalistic breakfast manipulations or testing environments, small samples, and insensitive cognitive tests. © 2016 American Society for Nutrition.

    2017-12-01

    We present an update on the Sun Radio Interferometer Space Experiment (SunRISE) mission concept, which was selected for a Step 2 study as part of the Small Explorer (SMEX) Mission of Opportunity (MoO) call. SunRISE is space-based sparse array, composed of six 6U CubeSats, designed to localize the radio emission associated with coronal mass ejections (CMEs) from the Sun. Radio emission from CMEs is a direct tracer of the particle acceleration in the inner heliosphere and potential magnetic connections from the lower solar corona to the larger heliosphere. Furthermore, CME radio emission is quite strong such that only a relatively small number of antennas is required, and a small mission would make a fundamental advancement. Indeed, the state-of-the-art for tracking CME radio emission is defined by single antennas (Wind/WAVES, Stereo/SWAVES) in which the tracking is accomplished by assuming a frequency-to-density mapping. This type of Heliophysics mission would be inherently cost prohibitive in a traditional spacecraft paradigm. However, the use of CubeSats, accompanied by the miniaturization of subsystem components, enables the development of this concept at lower cost than ever before. We present the most recent updates on this mission concept, starting from the concept's performance as compared to the required science and driving technical requirements. We then focus on the SunRISE mission concept of operations, which consists of six 6U CubeSats placed in a GEO graveyard orbit for 6 months to achieve the aforementioned science goals. The spacecraft fly in a passive formation, which allows them to form an interferometer while minimizing the impact on operations complexity. We also present details of the engineering design and the key trades being performed as part of the Step 2 concept study.

  7. Towards Using Smartphones to Refine Sunrise and Sunset Time Models

    Science.gov (United States)

    Wilson, Teresa; Bartlett, Jennifer L.

    2015-01-01

    Current atmospheric models used to predict the times of sunrise and sunset have a minimum error of about one minute. Particularly at higher latitudes, slight changes in refraction may result in significant discrepancies, such as causing the Sun to appear to set several minutes prematurely or remain continuously above the horizon for an unexpectedly long time. Atmospheric models could be better constrained by a substantial collection of observed sunset times with associated meteorological data such temperature, pressure and height of observer. We report on the development of a project recording the necessary data with a few smartphones that will then be the groundwork of a citizen science project.

  8. Stress, breakfast cereal consumption and cortisol.

    Science.gov (United States)

    Smith, A P

    2002-04-01

    Recent research has shown that regular consumption of breakfast cereal is associated with lower stress levels and reports of better physical and mental health. The present study examined this issue using an objective indicator of stress, salivary cortisol. The results showed that stress was associated with higher cortisol levels and daily consumption of breakfast cereal was associated with lower cortisol levels. Although it was not possible to rule out all the alternative explanations of the association between breakfast cereal consumption and cortisol, analyses did show that the effect could not be accounted for by general health or nutritional status. The effects of breakfast cereal consumption and stress were also independent, which shows that the effects of breakfast found here cannot be due to stress buffering. Further research manipulating the nutrient content of the breakfast cereal is now required to provide further information about the mechanisms underlying this effect.

  10. Does school breakfast benefit children's educational performance?

    Science.gov (United States)

    Fernald, L; Ani, C C; Grantham-mcgregor, S

    1997-09-01

    This article reviews several research studies on the impact of the lack of breakfast among students. Recent data reveal that about 20% of Nigerian children were wasted or had weight-for-height measurements under the 5th percentile of the US National Center for Health Statistics (NCHS) standard. In Ghana, 41% of children were underweight or had a weight-for-age under -2 standard deviations of the NCHS standards. In Tanzania, about 34% of children were underweight. Many more students in Africa are attending school, but many are leaving primary school early or failing secondary school examinations. It is argued that poor nutritional status affects children's ability to learn. Research reveals several hypotheses about how breakfast affects children's cognition, behavior, and school performance. Children may not attend school at all due to the inability to purchase food to eat at school, or insufficient food resources at home to provide sufficient energy to walk long distances to school. In four studies, two in the USA and the others in Peru and Jamaica, findings reveal that when undernourished children missed breakfast, they performed worse in tests of cognition. Adequately nourished children's performance was unaffected by missing breakfast. A study in four Jamaican schools found that children had more creative ideas when they received a breakfast for 2 weeks than when they did not receive breakfast. Two Swedish studies found that children with a high-calorie breakfast improved in cognition compared to those receiving a low-calorie breakfast. One study found that children in well-equipped classrooms paid more attention in class after having breakfast. Children in overcrowded classes and poorly equipped schools were less likely to pay attention after breakfast. Long-term effects are less well studied, but findings clearly support the benefits of breakfast.

    Full Text Available Bien qu’il y ait eu du croquant et du croustillant dans l’alimentation des Français avant l’époque contemporaine (pain, gâteaux, fruits frais ou secs sa place a augmenté récemment à la suite des changements intervenus dans le petit déjeuner. Le but de cet article est d’analyser historiquement la pénétration et la diffusion du croquant et du croustillant dans le petit déjeuner français. Celle ci s’est faite d’abord dans les villes sous l’influence de modèles étrangers et principalement Anglo-Saxons qui font une place importante au croustillant. Les partisans des nouveaux petits déjeuners à base de lait, de céréales et de fruits ne cherchaient pas seulement à promouvoir le végétarisme mais aussi à lutter contre la « dégénérescence » qui menaçait à leurs yeux la société moderne. Après avoir rappelé la naissance du petit déjeuner français, on étudiera le rôle des modèles étrangers dans l’évolution de la consommation d’aliments croustillants.Though crispy items were present in French food before the contemporary period (what with bread, cakes, fresh or dried fruits, they have recently played a more important part as breakfast underwent a series of changes. The aim of this article is to make an historical analysis of the emergence and spread of crispy food in the French breakfast. The influence of foreign and more especially Anglo-Saxon models contributed to increasing its importance. Those who advocated these new breakfasts at the beginning of the XXth century were convinced to fight also against “degeneracy” which they thought was a threat to modern society. I shall first briefly explain how the French breakfast was born, then I shall focus on the influence and impact of foreign models.

    Full Text Available Background: Adolescence is a time of rapid development that requires higher nutrient intake levels than in adulthood. However the habit of skipping breakfast has become very popular among adolescents. Skipping breakfast has negative effects such as difficulty in concentrating, growth impairment and decrease academic performance. Therefore, this study was conducted to identify the breakfast composisition of early adolescents in Jatinangor, Sumedang, Indonesia. Methods: A cross sectional study with non-probability sampling method, was conducted in a junior high school Jatinangor during the month of July 2013. Ninety six participants were included in this study. All the participants underwent an interview about the food intake for breakfast in seven days using eating pattern recall guidelines. Results: Overall, 37% of the respondents skipped breakfast. The mean of total calories among the adolescents who consumed breakfast was 286.06 (187.89 kcal. The amount of carbohydrate, fat and protein consumed was 29.23 (19.93 gram, 13.93 (13.29 gram and 8.78 (6.11 gram accordingly. The main reason for adolescent to skip breakfast was lack of time. Conclusions: Majority of the respondents have their breakfast before they go to school. Overall, the total calories comsumed is sufficient however the amount of protein consumed is low.

    To determine whether nutrient intake and academic and psychosocial functioning improve after the start of a universal-free school breakfast program (USBP). Information was gathered from 97 inner city students prior to the start of a USBP and again after the program had been in place for 6 months. Students who had total energy intakes of breakfast at school than children who were not at nutritional risk. Six months after the start of the free school breakfast programs, students who decreased their nutritional risk showed significantly greater: improvements in attendance and school breakfast participation, decreases in hunger, and improvements in math grades and behavior than children who did not decrease their nutritional risk. Participation in a school breakfast program enhanced daily nutrient intake and improvements in nutrient intake were associated with significant improvements in student academic performance and psychosocial functioning and decreases in hunger.

    Magneto-static models may overcome some of the issues facing force-free magnetic field extrapolations. So far they have seen limited use and have faced problems when applied to quiet-Sun data. Here we present a first application to an active region. We use solar vector magnetic field measurements gathered by the IMaX polarimeter during the flight of the Sunrise balloon-borne solar observatory in 2013 June as boundary conditions for a magneto-static model of the higher solar atmosphere above an active region. The IMaX data are embedded in active region vector magnetograms observed with SDO /HMI. This work continues our magneto-static extrapolation approach, which was applied earlier to a quiet-Sun region observed with Sunrise I. In an active region the signal-to-noise-ratio in the measured Stokes parameters is considerably higher than in the quiet-Sun and consequently the IMaX measurements of the horizontal photospheric magnetic field allow us to specify the free parameters of the model in a special class of linear magneto-static equilibria. The high spatial resolution of IMaX (110–130 km, pixel size 40 km) enables us to model the non-force-free layer between the photosphere and the mid-chromosphere vertically by about 50 grid points. In our approach we can incorporate some aspects of the mixed beta layer of photosphere and chromosphere, e.g., taking a finite Lorentz force into account, which was not possible with lower-resolution photospheric measurements in the past. The linear model does not, however, permit us to model intrinsic nonlinear structures like strongly localized electric currents.

    Breakfast is often thought to be the most important meal of the day as it is known to provide energy for the brain and improve learning. It is also known to contribute significantly to the total daily energy and nutrient intake. Skipping breakfast may affect performance during the rest of the day. To determine the level of breakfast skipping among medical students and its effect on their attention span and level of fatigue during clinical sessions. A descriptive cross-sectional study of breakfast eating habits among medical students at the University of Ghana Medical School, Korle Bu-Accra. The University of Ghana Medical School, Korle Bu-Accra. Questionnaires were distributed to second year (pre-clinical) medical students studying the basic sciences and clinical students in ophthalmology to be self-administered. Interview data was captured and analyzed using SPSS version 17.0. The total number of pre-clinical students recruited was 154 and clinical students 163 bringing to a total of 317 students made up of 203 males and 114 females (M: F=1.8:1). The overall breakfast skipping among the students was 71.92%. The prevalence among the pre-clinical students was 76.62% and clinical students 67.48%. Generally, breakfast skipping was significantly related to fatigue and poor attention during clinical sessions. This study suggests that the medical students, both pre-clinical and clinical, skip breakfast and this may affect their studies adversely.

    Radio emission from coronal mass ejections (CMEs) is a direct tracer of particle acceleration in the inner heliosphere and potential magnetic connections from the lower solar corona to the larger heliosphere. Energized electrons excite Langmuir waves, which then convert into intense radio emission at the local plasma frequency, with the most intense acceleration thought to occur within 20 R_S. The radio emission from CMEs is quite strong such that only a relatively small number of antennas is required to detect and map it, but many aspects of this particle acceleration and transport remain poorly constrained. Ground-based arrays would be quite capable of tracking the radio emission associated with CMEs, but absorption by the Earth's ionosphere limits the frequency coverage of ground-based arrays (nu > 15 MHz), which in turn limits the range of solar distances over which they can track the radio emission (concept: A constellation of small spacecraft in a geostationary graveyard orbit designed to localize and track radio emissions in the inner heliosphere. Each spacecraft would carry a receiving system for observations below 25 MHz, and SunRISE would produce the first images of CMEs more than a few solar radii from the Sun. Part of this research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.

    Breakfast is thought to be beneficial for cognitive and academic performance in school children. However, breakfast is the most frequently skipped meal, especially among adolescents. The aim of the current article was to systematically review the evidence from intervention studies for the effects of breakfast on cognitive performance in children and adolescents. The effects of breakfast were evaluated by cognitive domain and breakfast manipulation. A total of 45 studies reported in 43 articles were included in the review. Most studies considered the acute effect of a single breakfast (n = 34). The acute studies looked at breakfast compared with no breakfast (n = 24) and/or comparisons of breakfast type (n = 15). The effects of chronic school breakfast program interventions were evaluated in 11 studies. The findings suggest that breakfast consumption relative to fasting has a short-term (same morning) positive domain-specific effect on cognition. Tasks requiring attention, executive function, and memory were facilitated more reliably by breakfast consumption relative to fasting, with effects more apparent in undernourished children. Firm conclusions cannot be made about the acute effects of breakfast composition and the effects of chronic breakfast interventions because there are too few studies and these largely report inconsistent findings. This review also highlights methodologic limitations of the existing research. These include a lack of research on adolescents, few naturalistic breakfast manipulations or testing environments, small samples, and insensitive cognitive tests. PMID:27184287

    Extensive literature has addressed the acute cognitive effects of breaking a fast. Recent reviews in this line of work have synthesized available research on the cognitive consequences of fasting compared with nutrient intake and the cognitive effects of macronutrient consumption. These largely have been inconclusive, possibly in part because of selection criteria limiting the scope of studies covered. The purpose of the current review is to integrate the results of the literature examining the cognitive effects of breakfast and breakfast composition in adults with the use of a flexible definition of breakfast, specifically, any caloric intake after a fasting period of ≥8 h. This review includes 38 studies that examine the acute cognitive impact of breakfast and 16 studies that examine the effects of breakfast composition. Results suggest that healthy adults show a small but robust advantage for memory (particularly delayed recall) from consuming breakfast. Largely equivocal results emerge for attention and motor and executive function; there were no effects from breakfast on language. Regarding breakfast composition, a smaller number of studies and widely disparate methodology addressing this question preclude definitive conclusions about the effects of cognition. A subset of this literature examines these questions in the context of glucoregulation; the findings emphasize the importance of considering differences in glucoregulation in research designs, even among healthy cohorts. The limitations of this literature include methodologic differences, such as the use of different tests to measure cognitive constructs, as well as the effects of timing in test administration.

    At polar sunrise, gaseous elemental mercury (GEM) undergoes an exceptional dynamic exchange in the air and at the snow surface during which GEM can be rapidly removed from the atmosphere (the so-called atmospheric mercury depletion events (AMDEs)) as well as re-emitted from the snow within a few hours to days in the Polar Regions. Although high concentrations of total mercury in snow following AMDEs is well documented, there is very little data available on the redox transformation processes of mercury in the snow and the fluxes of mercury at the air/snow interface. Therefore, the net gain of mercury in the Polar Regions as a result of AMDEs is still an open question. We developed a new version of the global mercury model, GRAHM, which includes for the first time bidirectional surface exchange of GEM in Polar Regions in spring and summer by developing schemes for mercury halogen oxidation, deposition, and re-emission. Also for the first time, GOME satellite data-derived boundary layer concentrations of BrO have been used in a global mercury model for representation of halogen mercury chemistry. Comparison of model simulated and measured atmospheric concentrations of GEM at Alert, Canada, for 3 years (2002-2004) shows the model's capability in simulating the rapid cycling of mercury during and after AMDEs. Brooks et al. (1) measured mercury deposition, reemission, and net surface gain fluxes of mercury at Barrow, AK, during an intensive measurement campaign for a 2 week period in spring (March 25 to April 7, 2003). They reported 1.7, 1.0 +/- 0.2, and 0.7 +/- 0.2 microg m(-2) deposition, re-emission, and net surface gain, respectively. Using the optimal configuration of the model, we estimated 1.8 microg m(-2) deposition, 1.0 microg m(-2) re-emission, and 0.8 microg m(-2) net surface gain of mercury for the same time period at Barrow. The estimated net annual accumulation of mercury within the Arctic Circle north of 66.5 degrees is approximately 174 t with +/-7 t of

    To test the hypothesis that participation in the School Breakfast Program by low-income children is associated with improvements in standardized achievement test scores and in rates of absence and tardiness, children in grades 3 through 6 were studied in the Lawrence, Mass, public schools, where the School Breakfast Program was begun at the start of the second semester 1986-1987 school year. The changes in scores on a standardized achievement test and in rates of absence and tardiness before and after the implementation of the School Breakfast Program for children participating in the program were compared with those of children who also qualified but did not participate. Controlling for other factors, participation in the School Breakfast Program contributed positively to the 1987 Comprehensive Tests of Basic Skills battery total scale score and negatively to 1987 tardiness and absence rates. These findings suggest that participation in the School Breakfast Program is associated with significant improvements in academic functioning among low-income elementary school children.

    2016-01-01

    Current atmospheric models used to predict the times of sunrise and sunset have an error of one to four minutes at mid-latitudes (0° - 55° N/S). At higher latitudes, slight changes in refraction may cause significant discrepancies, including determining even whether the Sun appears to rise or set. While different components of refraction are known, how they affect predictions of sunrise/set has not yet been quantified. A better understanding of the contributions from temperature profile, pressure, humidity, and aerosols, could significantly improve the standard prediction. Because sunrise/set times and meteorological data from multiple locations will be necessary for a thorough investigation of the problem, we will collect this data using smartphones as part of a citizen science project. This analysis will lead to more complete models that will provide more accurate times for navigators and outdoorsman alike.

    2014-09-01

    Full Text Available Acquired brain injury (ABI often compromises the ability to carry out instrumental activities of daily living such as cooking. ABI patients’ difficulties with executive functions and memory result in less independent and efficient meal preparation. Accurately assessing safety and proficiency in cooking is essential for successful community reintegration following ABI, but in vivo assessment of cooking by clinicians is time-consuming, costly, and difficult to standardize. Accordingly, we examined the usefulness of a computerized meal preparation task (the Breakfast Task; Craik & Bialystok, 2006 as an indicator of real life meal preparation skills. Twenty-two ABI patients and 22 age-matched controls completed the Breakfast Task and the Rehabilitation Activities of Daily Living Survey (RADLS; Salmon, 2003. Patients also prepared actual meals, and were rated by members of the clinical team. As expected, the ABI patients had significant difficulty on all aspects of the Breakfast Task (failing to have all their foods ready at the same time, over- and under-cooking foods, setting fewer places at the table, and so on relative to controls. Surprisingly, however, patients’ Breakfast Task performance was not correlated with their in vivo meal preparation. These results indicate caution when endeavoring to replace traditional evaluation methods with computerized tasks for the sake of expediency.

    Ellerman Bombs are signatures of magnetic reconnection, which is an important physical process in the solar atmosphere. How and where they occur is a subject of debate. In this paper, we analyze Sunrise/IMaX data, along with 3D MHD simulations that aim to reproduce the exact scenario proposed for the formation of these features. Although the observed event seems to be more dynamic and violent than the simulated one, simulations clearly confirm the basic scenario for the production of EBs. The simulations also reveal the full complexity of the underlying process. The simulated observations show that the Fe i 525.02 nm line gives no information on the height where reconnection takes place. It can only give clues about the heating in the aftermath of the reconnection. However, the information on the magnetic field vector and velocity at this spatial resolution is extremely valuable because it shows what numerical models miss and how they can be improved.

    2013-07-02

    The objective was to examine the effect of consuming breakfast on subsequent energy intake. Participants who habitually ate breakfast and those who skipped breakfast were recruited for two studies. Using a randomized crossover design, the first study examined the effect of having participants consume either (a) no breakfast, (b) a high carbohydrate breakfast (335 kcals), or (c) a high fiber breakfast (360 kcals) on three occasions and measured ad libitum intake at lunch. The second study again used a randomized crossover design but with a larger, normal carbohydrate breakfast consumed ad libtum. Intake averaged 624 kcals and subsequent food intake was measured throughout the day. Participants ate only foods served from the Cornell Human Metabolic Research Unit where all foods were weighed before and after consumption. In the first study, neither eating breakfast nor the kind of breakfast consumed had an effect on the amount consumed at lunch despite a reduction in hunger ratings. In the second study, intake at lunch as well as hunger ratings were significantly increased after skipping breakfast (by 144 kcal), leaving a net caloric deficit of 408 kcal by the end of the day. These data are consistent with published literature demonstrating that skipping a meal does not result in accurate energy compensation at subsequent meals and suggests that skipping breakfast may be an effective means to reduce daily energy intake in some adults.

    Full Text Available Abstract Background Previous studies have shown that fasting increases lead absorption in the gastrointestinal tract of adults. Regular meals/snacks are recommended as a nutritional intervention for lead poisoning in children, but epidemiological evidence of links between fasting and blood lead levels (B-Pb is rare. The purpose of this study was to examine the association between eating a regular breakfast and B-Pb among children using data from the China Jintan Child Cohort Study. Methods Parents completed a questionnaire regarding children's breakfast-eating habit (regular or not, demographics, and food frequency. Whole blood samples were collected from 1,344 children for the measurements of B-Pb and micronutrients (iron, copper, zinc, calcium, and magnesium. B-Pb and other measures were compared between children with and without regular breakfast. Linear regression modeling was used to evaluate the association between regular breakfast and log-transformed B-Pb. The association between regular breakfast and risk of lead poisoning (B-Pb≥10 μg/dL was examined using logistic regression modeling. Results Median B-Pb among children who ate breakfast regularly and those who did not eat breakfast regularly were 6.1 μg/dL and 7.2 μg/dL, respectively. Eating breakfast was also associated with greater zinc blood levels. Adjusting for other relevant factors, the linear regression model revealed that eating breakfast regularly was significantly associated with lower B-Pb (beta = -0.10 units of log-transformed B-Pb compared with children who did not eat breakfast regularly, p = 0.02. Conclusion The present study provides some initial human data supporting the notion that eating a regular breakfast might reduce B-Pb in young children. To our knowledge, this is the first human study exploring the association between breakfast frequency and B-Pb in young children.

  2. Does breakfast make a difference in school?

    Science.gov (United States)

    Pollitt, E

    1995-10-01

    This article reviews selectively the literature on the effects of breakfast on cognition and school performance. The focus is on studies published in refereed journals after 1978 that tested those effects on well-nourished and nutritionally at-risk children. In at-risk subjects (defined by clinical history and anthropometry), a morning and overnight fast had adverse effects on cognition, particularly the speed of information retrieval in working memory. Contradictions in the data from different studies prevent definitive conclusions on whether well-nourished children experience similar functional deficits. Nonetheless, available information suggests that brain function is sensitive to short-term variations in the availability of nutrient supplies. Moreover, well-conducted evaluations suggest that the availability of feeding programs in public schools throughout the academic year increases the probability that children will eat breakfast and improve their educational status.

    To determine predictors of fluid milk waste in a Breakfast in the Classroom School Breakfast Program. Cross-sectional with 3 repeated measures/classroom. Elementary schools in a medium-sized, low-income, urban school district. Twenty third- through fourth-grade classrooms across 6 schools. Dependent variables include percentage of total and served milk wasted. Independent variables included observed daily menu offerings, program factors, and teacher and student behavior. Descriptive statistics were used to characterize variables across classrooms and schools. Multilevel mixed-effects models were used to test associations between predictors and outcomes of interest. P ≤ .05 was considered statistically significant. Total milk waste increased 12% when juice was offered and 3% for each additional carton of unserved milk. Teacher encouragement to take and/or consume breakfast was associated with a 5% and 9% increase in total and served milk waste, respectively. When students were engaged in other activities in addition to eating breakfast, total milk waste decreased 10%. Beverage offerings were predictive of greater total milk waste. Teacher and student behavior also appeared to influence milk consumption. Findings suggest that specific changes to School Breakfast Program implementation policies and practices could have an important role in waste mitigation.

    To experimentally compare the effects of eating or skipping breakfast on energy expenditure, activity levels and dietary habits. A randomised cross-over trial, lasting 2 weeks. Participants were provided breakfast during one week and were required to fast until mid-day during the other week. University campus. Forty-nine participants (twenty-six female and twenty-three male participants) were recruited. Food intake was monitored using food diaries, and energy expenditure was assessed using pedometers and heart rate monitors. Morningness-eveningness, physical activity and health were assessed using validated questionnaires. Across all participants, daily energy expenditure did not differ between the two experimental conditions. Total energy intake over 24 h did not vary with condition (male participants: 8134 (sd 447) kJ/d and 7514 (sd 368) kJ/d; female participants: 7778 (sd 410) kJ/d and 7531 (sd 535) kJ/d, for the breakfast and no-breakfast conditions, respectively). However, when comparing habitual breakfast eaters with those with irregular or breakfast-skipping habits, it was found that male non-habitual breakfast eaters consumed significantly (P = 0·029) more energy during the breakfast condition. Furthermore, female participants who were habitual breakfast eaters were found to eat significantly (P = 0·005) more and later in the day under the no-breakfast condition. Although the suggestion that breakfast is a behavioural marker for appropriate dietary and physical activity patterns is not refuted by the present findings, our data suggest that the effect of breakfast may vary as a function of gender and morning eating habits, and thus there may be other mechanisms that link BMI and breakfast consumption behaviour.

    Full Text Available There is limited evidence in Australia that compares the nutritional impact of a breakfast cereal breakfast to a non-cereal breakfast, and includes the type of cereal. This study investigated the impact of breakfast choice and the total sugar content of breakfast cereal on nutrient intakes and anthropometric measures among Australian children and adolescents. Data from 2 to 18-year-old in the 2011–2012 National Nutrition and Physical Activity Survey were used (n = 2821. Participants were classified as breakfast cereal consumers (minimally pre-sweetened (MPS or pre-sweetened (PS, non-cereal breakfast consumers, or breakfast skippers. Foods consumed for breakfast, foods added to the cereal bowl, and the impact of breakfast choice on daily nutrient intakes and anthropometric measures were determined. Although only 9% of children skipped breakfast, 61% of skippers were aged 14–18 years. Among breakfast consumers, 49% had breakfast cereal, and 62% of these exclusively consumed MPS cereal. Breakfast skippers had a higher saturated fat intake than breakfast cereal consumers, and lower intakes of dietary fibre and most micronutrients (p < 0.001. Compared with non-cereal breakfast consumers, breakfast cereal consumers had additional free sugars intake, lower sodium, and higher total sugars, carbohydrate, dietary fibre, and almost all other micronutrients (p < 0.001. The only difference in nutrient intakes between MPS and PS cereal consumers was higher folate among PS consumers. No associations between anthropometric measures and breakfast or breakfast cereal choice were found. The highest prevalence of breakfast skipping was among 14–18-year old. Breakfast cereal consumers had higher intakes of dietary fibre and most micronutrients compared with non-cereal breakfast consumers and skippers, and almost no differences were found between MPS and PS cereal consumers.

    It has been suggested that breakfast omission, as opposed to breakfast consumption, has the detrimental effects on cognitive function. However, the effects of acute exercise following breakfast omission on cognitive function are poorly understood, particularly during exercise. The purpose of this study was to examine the interactive effects of breakfast and exercise on cognitive function. Ten participants completed cognitive tasks at rest and during exercise in the breakfast consumption or omission conditions. Blood glucose concentration was measured immediately after each cognitive task. We used cognitive tasks to assess working memory [Spatial Delayed Response (DR) task] and executive function [Go/No-Go (GNG) task]. The participants cycled ergometer for 30 min while keeping their heart rate at 140 beats·min(-1). Accuracy of the GNG task was lower at rest in the breakfast omission condition than that in the breakfast consumption condition (Go trial: P=0.012; No-Go trial: P=0.028). However, exercise improved accuracy of the Go trial in the breakfast omission condition (P=0.013). Reaction time in the Go trial decreased during exercise relative to rest in both conditions (P=0.002), and the degree of decreases in reaction time was not different between conditions (P=0.448). Exercise and breakfast did not affect the accuracy of the Spatial DR task. The present results indicate that breakfast omission impairs executive function, but acute exercise improved executive function even after breakfast omission. It appears that beneficial effects of acute exercise on cognitive function are intact following breakfast omission. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The aim of the study was to evaluate the frequency of breakfast and other meal consumption by adolescents and to assess the relationship between the first and the last meal consumption and sex, body mass index (BMI, and middle school and high school students’ education level. The study was conducted in 2013–2014 among 3009 students (1658 girls and 1351 boys from middle s and high schools in Krakow and Silesia (Poland. The data was obtained from questionnaires that were analyzed with a logistic regression model for measurable and dichotomous variables. Breakfast consumers were seen to eat other meals (second breakfast, lunch, dessert, supper significantly more often than breakfast skippers. The main meal consumption habits depend on sex and change as adolescents age. Being a girl and a high school student predisposed participants to skip breakfast and supper more often. The BMI of breakfast consumers does not differ significantly from the BMI of breakfast skippers, so BMI might thus not be a sufficient marker of breakfast consumption regularity and dietary habits in an adolescent group. The importance of regularly eaten meals, especially breakfast, together with adequate daily dietary energy intake are beneficial for physical and psychological development and cannot be overestimated in nutritional education and it is necessary to promote healthy eating behavior for well-being in later adult life.

    Rosemeyre França de Paula FIUZA

    Full Text Available ABSTRACT Objective To analyze the prevalence and factors associated with breakfast skipping among adolescents. Methods Cross-sectional study, with adolescents aged 10-17 years, evaluated between 2009 and 2011, belonging to a cohort study in the Central-West region of Brazil. Breakfast skipping was considered as not having breakfast every day. Demographic, socioeconomic, and lifestyle factors were evaluated through a questionnaire. Anthropometric assessment included measurement of weight and height, which were used to classify weight status using body mass index. Poisson regression was used to assess the association of breakfast skipping with demographic and socioeconomic variables, lifestyle factors, and weight status. Results Among 1,716 Brazilian adolescents evaluated, 36.2% reported not consuming breakfast every day, with the highest prevalence among girls (p=0.03. After adjusting for age and economic class, breakfast skipping was associated with not consuming breakfast with parents and morning shift at school, in both genders, and with obesity only in boys. Lifestyle factors such as alcohol consumption, physical activity, diet quality, and smoking were not associated with skipping breakfast. Conclusion The omission of breakfast was observed in more than a third of adolescents, being associated with demographic and lifestyle factors. In the public health perspective, the importance of encouraging the consumption of this meal is highlighted, with actions involving the school environment and the family.

    Algorithms that predict sunrise and sunset times currently have an uncertainty of one to four minutes at mid-latitudes (0° - 55° N/S) due to limitations in the atmospheric models they incorporate. At higher latitudes, slight changes in refraction can cause significant discrepancies, including difficulties determining whether the Sun appears to rise or set. While different components of refraction are known, how they affect predictions of sunrise/set has not yet been quantified. A better understanding of the contributions from temperature profile, pressure, humidity, and aerosols could significantly improve the standard prediction.We present a sunrise/set calculator that interchanges the refraction component by varying the refraction model. We, then, compared these predictions with data sets of observed rise/set times taken from Mount Wilson Observatory in California, University of Alberta in Edmonton, Alberta, and onboard the SS James Franco in the Atlantic. A thorough investigation of the problem requires a more substantial data set of observed rise/set times and corresponding meteorological data from around the world.We have developed a mobile application, Sunrise & Sunset Observer, so that anyone can capture this astronomical and meteorological data using their smartphone video recorder as part of a citizen science project. The Android app for this project is available in the Google Play store. Videos can also be submitted through the project website (riseset.phy.mtu.edu). Data analysis will lead to more complete models that will provide higher accuracy rise/set predictions to benefit astronomers, navigators, and outdoorsmen everywhere.

    Breakfast consumption can entail nutritional advantages positively affecting food choices. This study investigated the effect of minor changes in breakfast composition on the perceived attributes of foods, both at breakfast and at lunchtime. Four breakfasts were defined considering nutritional and perceptual factors. Three breakfasts varied just for a single cereal-based chocolate-containing food item, while a control breakfast mimicked fasting conditions. Breakfast perception was assessed before and after consumption. Subjects rated breakfast energy content on the basis of single items, while judged breakfast healthiness as a whole, suggesting that the combination of different ingredients can modify the perceived health value of foods. Additionally, 4 h after breakfast, a perceptual evaluation of lunch-related food images was performed, without differences among breakfasts. This study extends current knowledge on the relationship between subjective perceptual attributes and objective energy value and food composition, as well as on breakfast impact on food perception at lunchtime.

    The Sun Radio Interferometer Space Experiment (SunRISE) is a NASA Heliophysics Explorer Mission of Opportunity that was recently awarded phase A funding. SunRISE's main science goals are to localize the source of particle acceleration in coronal mass ejections to 1/4th of their width, and trace the path of electron beams along magnetic field lines out to 20 solar radii. These processes generate cascading Type II and III bursts that have ever only been detected in low frequencies with single spacecraft antenna. These bursts emit below the ionospheric cutoff of 10 MHz past 2 solar radii, so a synthetic aperture made from multiple space antennae is needed to pinpoint the origin of these bursts. In this work, we create an end to end simulation of the data processing pipeline of SunRISE, which uses 6 small satellites to do this localization. One of the main inputs of the simulation is a ground truth of what we want the array to image. We idealized this as an elliptical Gaussian offset from the sun, which previous modeling suggests is a good approximation of what SunRISE would see in space. Another input is an orbit file describing the positions of all the spacecraft. The simulated orbit determinations are made with GPS sidelobes and have an error associated with the recovered positions. From there we compute the Fourier coefficients every antenna will see, then apply the correct phase lags and multiply each pair of coefficients to simulate the process of correlation. We compute the projected UVW coordinates and put these along with the correlated visibilities into a CASA MS file. The correlated visibilities are compared to CASA's simulated visibilities at the same UVW coordinates, verifying the accuracy of our method. The visibilities are then subjected to realistic thermal noise, as well as phase noise from uncertainties in the spacecraft position. We employ CASA's CLEAN algorithm to image the data, and CASA's imfit algorithm to estimate the parameters of the imaged

    The Bath Breakfast Project is a series of randomised controlled trials exploring the effects of extended morning fasting on energy balance and health. These trials were categorically not designed to answer whether or not breakfast is the most important meal of the day. However, this review will philosophise about the meaning of that question and about what questions we should be asking to better understand the effects of breakfast, before summarising how individual components of energy balance and health respond to breakfast v. fasting in lean and obese adults. Current evidence does not support a clear effect of regularly consuming or skipping breakfast on body mass/composition, metabolic rate or diet-induced thermogenesis. Findings regarding energy intake are variable, although the balance of evidence indicates some degree of compensatory feeding later in the day such that overall energy intake is either unaffected or slightly lower when breakfast is omitted from the diet. However, even if net energy intake is reduced, extended morning fasting may not result in expected weight loss due to compensatory adjustments in physical activity thermogenesis. Specifically, we report that both lean and obese adults expended less energy during the morning when remaining in the fasted state than when consuming a prescribed breakfast. Further research is required to examine whether particular health markers may be responsive to breakfast-induced responses of individual components of energy balance irrespective of their net effect on energy balance and therefore body mass.

    Full Text Available Background: Breakfast skipping was related to obesity and obesity has been associated with psychological disorders, but limited data are available linking breakfast consumption to psychological symptoms. Objective: The association between breakfast consumption and psychological disorders, including depression and anxiety, was studied among Iranian adults. Methods: This cross-sectional study was conducted on 4378 healthy adults in Isfahan, Iran. Breakfast consumption was assessed using a validated detailed dietary habits’ questionnaire; and depression and anxiety using an Iranian validated Hospital Anxiety and Depression Scale (HADS questionnaire. Psychological distress was also examined by means of Iranian validated version of General Health Questionnaire. Findings: Overall, 611 numbers (13.95% of study participants had anxiety, 1253 numbers (28.62% depression, and 1015 numbers (23.18% probable mental disorders symptoms. After controlling for the confounding variables, participants with every day breakfast consumption had lower odds for depression symptoms (OR: 0.49; 95% CI: 0.36-0.66 compared with those with the least frequent intake of breakfast, even after further adjustment for BMI (OR: 0.47; 95% CI: 0.34- 0.63. Frequent breakfast consumption was inversely associated with anxiety before and after controlling for BMI (P<0.001. The same findings were obtained for probable mental disorders (P<0.001. Conclusion: This study showed an inverse relation between breakfast consumption and symptoms of depression, anxiety, and probable mental disorders among Iranian adults. Further prospective studies are needed to confirm these findings.

    Skipping breakfast can be potentially harmful because breakfast consumption is considered one of the important health-related behaviors that benefit physical and mental health. As the rate of depression has increased recently, we investigated the association between the frequency of eating breakfast and depression in adults. We obtained the data from the 2013 Korean Community Health Survey; a total of 207,710 survey participants aged 20 years or over were studied. Participants were categorized into three groups by the frequency of breakfast consumption as follows: "seldom," "sometimes," and "always." We performed a multiple logistic regression to investigate the association between breakfast consumption and depressive mood. Subgroup analyses were conducted by stratifying socioeconomic variables controlling for variables known to be associated with depressive symptoms. Participants who had breakfast seldom or sometimes had higher depressive symptoms than those who always ate breakfast ("seldom": OR = 1.43, 95% CI 1.36-1.52; "sometimes": OR = 1.32, 95% CI 1.23-1.40). Subgroup analyses showed that this association was more marked in those who were 80 years or older, those who had low household income, or those with elementary school education level or less. The result of this study suggests that lack of breakfast consumption is associated with depression among adults with different socioeconomic factors. Copyright © 2017 Elsevier Ltd.

    2017-12-15

    Most of the studies investigating the effects of breakfast on cognitive performance have compared performance in subjects who have or have not consumed this meal. However, characteristics of breakfast itself may influence mental abilities. Moreover, as far as the positive effects of having breakfast is more evident, research may focus on the specific characteristics of an adequate breakfast. To update an existing systematic review, published at the beginning of 2014, on the role of nutrient composition and/or energy intake at breakfast on the accomplishment of school-related tasks and cognition, we carried out a systematic review of the literature through PUBMED database. From the literature search, we identified 39 papers, of which 2 were eligible according to our inclusion criteria. Both the selected papers concerned randomized crossover studies on the acute effect of breakfast carried out in a school setting in the United Kingdom. Both studies compared 2 iso-energetic breakfasts with a similar macronutrient composition; however, the alternative breakfasts were meant to differ in terms of glycemic index or glycemic load. The effects of breakfast composition were investigated on memory, attention, and information processing in both studies. However, different tests and subdomains were considered. Studies on these issues are still inconsistent and quantitatively insufficient to draw firm conclusions. While the hypothesis of a better mental performance with breakfast>20% daily energy intake still needs confirmation, there does appear to be extra evidence that a lower postprandial glycemic response is beneficial to mental performance.

    We consider the scalar integral associated to the 3-loop sunrise graph with a massless line, two massive lines of equal mass M, a fourth line of mass equal to Mx, and the external invariant timelike and equal to the square of the fourth mass. We write the differential equation in x satisfied by the integral, expand it in the continuous dimension d around d=4 and solve the system of the resulting chained differential equations in closed analytic form, expressing the solutions in terms of harmonic polylogarithms. As a byproduct, we give the limiting values of the coefficients of the (d-4) expansion at x=1 and x=0

    We show that configuration space techniques can be used to efficiently calculate the complete Laurent series ε-expansion of sunrise-type diagrams to any loop order in D-dimensional space-time for any external momentum and for arbitrary mass configurations. For negative powers of ε the results are obtained in analytical form. For positive powers of ε including the finite ε 0 contribution the result is obtained numerically in terms of low-dimensional integrals. We present general features of the calculation and provide exemplary results up to five-loop order which are compared to available results in the literature. (orig.)

    1982-10-01

    Breakfast habits by using questionnaires, were established in a total of 4717 South African pupils of 16 to 18 yr. In the groups of rural and urban Black, Indian, European-African-Malay, and white pupils studied, respective proportions who had no solid breakfast (both sexes combined) were approximately 21, 19, 13, 13, and 14%. Proportions who had only porridge or bread (or toast) plus drink were 77, 73, 61, 71, and 56%. Such breakfast provided ranges of means of 223 to 345 kcal, 9 to 14 g protein, 7 to 18 g fat, 51 to 185 mg calcium, and 3.2 to 5.1 mg iron. Proportions who had a cooked breakfast (including egg, meat, fish), eaten with or without a cereal food, were 1, 4, 17, 8, and 29%. Such meals contributed means of 495 to 704 kcal, 11 to 26 g protein, 24 to 39 g fat, 110 to 225 mg calcium, and 3.9 to 5.5 mg iron. In the South African groups studied, the issue of breakfast or no breakfast had no clear-cut bearing on weight, height, class position, or frequency of absence from school. The degree by which, in a given community, nutrition in general and breakfast in particular, regulates health and/or academic performance, needs proper research in prospective studies.

    The aim of the present study was to examine the combined effects of breakfast glycaemic index (GI) and a mid-morning bout of exercise on adolescents' cognitive function. Participants were randomly allocated to a high or low GI breakfast group in a mixed research design, where each participant completed two experimental trials (exercise and resting). Forty-two adolescents (12.4±0.5 years old), undertook a bout of exercise (ten repeats of level one of the multi-stage fitness test; exercise trial) or continued to rest (resting trial) following consumption of either a high or low GI breakfast. A battery of cognitive function tests (visual search test, Stroop test and Sternberg paradigm) was completed 30 min before and 45 min following the exercise. Average heart rate during exercise was 170±15 beats·min(-1). On the complex level of the Stroop test, response times improved across the morning following the low GI breakfast on both the exercise and resting trials, though the improvement was greatest on the exercise trial. However, response times only improved on the resting trial following the high GI breakfast (p=0.012). On the 5 letter level of the Sternberg paradigm, response times improved across the morning following the low GI breakfast (regardless of exercise) and only on the exercise trial following the high GI breakfast (p=0.019). The findings of the present study suggest that the combined effects of breakfast GI and exercise in adolescents depend upon the component of cognitive function examined. A low GI breakfast and mid-morning bout of exercise were individually beneficial for response times on the Sternberg paradigm, whereas they conferred additional benefits for response times on the Stroop test.

    This article reviews the history of the US Department of Agriculture School Breakfast Program (SBP) and provides a synthesis of factors influencing participation rates. Certain children are more likely to participate than others, such as those in lower grades and those from low-income households, and African American, Hispanic, and male students. A few studies in the past 25 y have examined the effectiveness of the SBP in improving the diets and nutritional status of children. The overall pattern that emerges from these studies is that the SBP contributes to improved nutrient intake in program participants. Less attention has been devoted to assessing the effects of SBP on cognitive development. Some of the evidence reviewed here suggests that the SBP significantly improves school performance and reduces absenteeism and tardiness. Future directions for research and operation of the SBP are discussed in light of the changing dietary profile of American children.

    Despite the fact that the total energy intake of Japanese people has decreased, the percentage of obese people has increased. This suggests that the timing of meals is related to obesity. The purpose of the study was to investigate the relationship between the timing of meals and obesity, based on analyses of physical measurements, serum biochemical markers, nutrient intake, and lifestyle factors in the context of Chrononutrition. We analyzed data derived from 766 residents of Toon City (286 males and 480 females) aged 30 to 79 years who underwent detailed medical examinations between 2011 and 2013. These medical examinations included. (1) physical measurements (waist circumference, blood pressure, etc.); (2) serum biochemical markers (total cholesterol, etc.); (3) a detailed questionnaire concerning lifestyle factors such as family structure and daily habits (22 issues), exercise and eating habits (28 issues), alcohol intake and smoking habits; (4) a food frequency questionnaire based on food groups (FFQg); and (5) a questionnaire concerning the times at which meals and snacks are consumed. The values for body mass index (BMI) and waist circumference were higher for participants who ate dinner less than three hours before bedtime (3-h group). The Chi-square test showed that there was a significant difference in eating habits, e.g., eating snacks, eating snacks at night, having dinner after 8 p.m., and having dinner after 9 p.m., between the 3-h group. Multiple linear regression analysis showed that skipping breakfast significantly influenced both waist circumference (β = 5.271) and BMI (β = 1.440) and that eating dinner influenced BMI (β = 0.581). Skipping breakfast had a greater influence on both waist circumference and BMI than eating dinner <3-h before going to bed.

    In order to examine the effect of energy intake at breakfast on school performance, 151 grade three school children from four classes of two schools were sampled for this study. Children were randomly assigned to breakfast A or B on any given day. They were provided with breakfast with either high or low energy content at school over a period of 5 successive days. The remained foods were collected and weighed. Performance tests including addition, multiplication, number checking, logic, creativity, physical endurance, visual-analogue scales were applied at the third or fourth period of courses in the morning on Tuesday through Friday during the experimental week. The teachers involved in the study were blind to the kind of treatment. No significant effect of energy intake at breakfast on these performance indicators was found in this study.

    To reduce the amount of sodium chloride in breakfast cereals without changing their properties, it is necessary to understand the role of this salt. Hence, a model system was developed. This model, composed of native waxy maize starch, glucose and a mixture of amino-acids generated similar colour and residual volatiles after heating compared to commercial breakfast cereals. Systematically designed experiments used this model to study the influence of NaCl concentration (0 % to 5.44 %) on colo...

    Breakfast models among children are an issue of public health concern given the association between breakfast and school performance and its potential relationship with obesity. Food intake, energy, and nutrients in the breakfast of 32 school aged children (11-years olds) and its relationship with body mass index (BMI, kg/m2) were examined. The analysis was made by means of anthropometric measurements and a record of weekly food intake using the accurate weighed amount method. The percentage of studied children with overweight/obesity reached 46.9 (weight for height > 90 percentile). The proportional calorie intake in breakfast was lower than that recommended (16.6%). The association observed between caloric percentage of breakfast regarding daily energy and BMI was not significant. Nevertheless, significant correlations were found between fruit group (Pearson r = 0.6286) and protein foods (Pearson r = -0.7653) with BMI. The amount of total lipids (34.4%) and saturated lipids (19.4% in breakfast exceed the recommendations. Further studies are necessary to confirm these data and serve as basis for the design of nutritional education programs.

    Full Text Available Tourist ascents of mountain peaks before sunrise are increasingly popular. Babia Góra (Western Carpathians is a peak on the Polish-Slovak border frequently visited by a great number of tourists at sunrise. The main objective of our research, based on the case study of Babia Gora, was to answer a more general question whether the sunrise can be considered a tourist attraction. The research included the observation and description of every sunrise at summer holiday weekends during 2012 from the peak of Babia Góra as well as the collection of data on the number of tourists and weather conditions. Survey interviews, using questionnaire, with randomly selected hikers present on the peak of Babia Góra at sunrise (269 were conducted. The investigation showed that during summer holiday sunrises there were a maximum of 130 people on the summit of Babia Góra at the same time. Most of the surveyed people (84% agreed that the opportunity to observe the sunrise was one of the pull factors for them. This confirms the hypothesis that sunrise constitutes a tourist attraction.

    To test (1) whether children will consume low-sugar ready-to-eat (RTE) cereals and (2) the effects of serving high- versus low-sugar cereals on the consumption of cereal, refined sugar, fresh fruit, and milk. Using an experimental design, we randomly assigned children (n = 91) who were attending summer day camp to receive a breakfast that included either the choice of 1 of 3 high-sugar cereals (high-sugar condition) or low-sugar cereals (low-sugar condition), as well as low-fat milk, orange juice, bananas, strawberries, and sugar packets. Participants served themselves and completed a background questionnaire after eating. Researchers measured the amount and calories consumed of each food. In both conditions, children reported "liking" or "loving" the cereal they chose. Children in the low-sugar cereal condition consumed, on average, slightly more than 1 serving of cereal (35 g), whereas children in the high-sugar condition consumed significantly more (61 g) and almost twice the amount of refined sugar in total (24.4 vs 12.5 g). Milk and total calories consumed did not differ significantly between conditions, but children in the low-sugar condition were more likely to put fruit on their cereal (54% vs 8%) and consumed a greater portion of total calories from fresh fruit (20% vs 13%). Compared with serving low-sugar cereals, high-sugar cereals increase children's total sugar consumption and reduce the overall nutritional quality of their breakfast. Children will consume low-sugar cereals when offered, and they provide a superior breakfast option.

    In facing future developments in health care, scenario planning offers a complementary approach to traditional strategic planning. Whereas traditional strategic planning typically consists of predicting the future at a single point on a chosen time horizon and mapping the preferred plans to address such a future, scenario planning creates stories about multiple likely potential futures on a given time horizon and maps the preferred plans to address the multiple described potential futures. Each scenario is purposefully different and specifically not a consensus worst-case, average, or best-case forecast; nor is scenario planning a process in probabilistic prediction. Scenario planning focuses on high-impact, uncertain driving forces that in the authors' example affect the field of radiology. Uncertainty is the key concept as these forces are mapped onto axes of uncertainty, the poles of which have opposed effects on radiology. One chosen axis was "market focus," with poles of centralized health care (government control) vs a decentralized private market. Another axis was "radiology's business model," with one pole being a unified, single specialty vs a splintered, disaggregated subspecialty. The third axis was "technology and science," with one pole representing technology enabling to radiology vs technology threatening to radiology. Selected poles of these axes were then combined to create 3 scenarios. One scenario, termed "entrepreneurialism," consisted of a decentralized private market, a disaggregated business model, and threatening technology and science. A second scenario, termed "socialized medicine," had a centralized market focus, a unified specialty business model, and enabling technology and science. A third scenario, termed "freefall," had a centralized market focus, a disaggregated business model, and threatening technology and science. These scenarios provide a range of futures that ultimately allow the identification of defined "signposts" that can

    Most studies showing that children consuming breakfast have better nutrient intakes, diet quality, and lower weight than breakfast skippers have the incorrect premise that breakfast meals are homogeneous. The purpose of this study was to classify breakfast meals into patterns and determine the association of the breakfast patterns with daily and breakfast nutrient intakes, diet quality, and weight. Data from children (2-18 years of age; N = 14,200) participating in the National Health and Nutrition Examination Survey 2001-2008 were used. Intake was determined from one day 24-hour dietary recalls. Diet quality was measured using the Healthy Eating Index-2005 (HEI-2005). Body mass index (BMI) z-scores were determined. Twelve patterns (including No Breakfast [∼19% of population]), explaining 63% of the variance in energy from breakfast, were examined. Covariate adjusted general linear models were used to compare outcome variables of consumers of different patterns with breakfast skippers. The p value was Bonferroni corrected (eat Cereal (RTEC)/ LFM, RTEC/LFM, Cooked Cereal/Milk/FJ, and Whole Fruit patterns had higher total HEI-2005 scores than breakfast skippers; those consuming the MPF/ Grain/FJ pattern had lower diet quality than breakfast skippers. Consumption of the Grain/ LFM/Sweets/FJ, PSRTEC/whole milk, Soft Drinks/ FJ/Grain/Potatoes, RTEC/whole milk, and Cooked Cereal/ Milk/ FJ patterns was associated with lower BMI z-scores than seen in breakfast skippers. There are dietary and weight advantages of consuming breakfast, especially breakfasts that include grains, cereals, LFM, and fruit/ FJ, in contrast to the potential adverse effects of skipping breakfast.

    Gaseous elemental mercury (Hg0) is a globally distributed air toxin with a long atmospheric residence time. Any process that reduces its atmospheric lifetime increases its potential accumulation in the biosphere. Our data from Barrow, AK, at 71 degrees N show that rapid, photochemically driven...... oxidation of boundary-layer Hg0 after polar sunrise, probably by reactive halogens, creates a rapidly depositing species of oxidized gaseous mercury in the remote Arctic troposphere at concentrations in excess of 900 pg m(-3). This mercury accumulates in the snowpack during polar spring at an accelerated...... rate in a form that is bioavailable to bacteria and is released with snowmelt during the summer emergence of the Arctic ecosystem. Evidence suggests that this is a recent phenomenon that may be occurring throughout the earth's polar regions. Udgivelsesdato: 2002-Mar-15...

    2018-06-01

    We introduce a class of iterated integrals that generalize multiple polylogarithms to elliptic curves. These elliptic multiple polylogarithms are closely related to similar functions defined in pure mathematics and string theory. We then focus on the equal-mass and non-equal-mass sunrise integrals, and we develop a formalism that enables us to compute these Feynman integrals in terms of our iterated integrals on elliptic curves. The key idea is to use integration-by-parts identities to identify a set of integral kernels, whose precise form is determined by the branch points of the integral in question. These kernels allow us to express all iterated integrals on an elliptic curve in terms of them. The flexibility of our approach leads us to expect that it will be applicable to a large variety of integrals in high-energy physics.

    This November 13, 1995, photograph of the F-15 Advanced Controls Technology for Integrated Vehicles (ACTIVE) at NASA's Dryden Flight Research Center, Edwards, California, shows the aircraft on a test stand at sunrise. Not shown in this photograph are the aircraft's two new Pratt & Whitney nozzles that can turn up to 20 degrees in any direction. These nozzles give the aircraft thrust control in the pitch (up and down) and yaw (left and right) directions. This will reduce drag and increase fuel economy or range as compared with conventional aerodynamic controls, which increase the retarding forces (drag) acting upon the aircraft. These tests could result in significant performance increases for military and commercial aircraft. The research program is the product of a collaborative effort by NASA, the Air Force's Wright Laboratory, Pratt & Whitney, and McDonnell Douglas Aerospace. The aircraft was originally built as an F-15B (Serial #71-0290).

    Breakfast skipping (BS) is closely associated with overeating (in the evening), weight gain and obesity. It is unclear whether the addition of breakfast, with emphasis on dietary protein, leads to better appetite and energy intake regulation in adolescents. The purpose of the study was to examine the impact of addition of a normal-protein (PN) breakfast vs protein-rich (PR) breakfast on appetite and food intake in 'breakfast-skipping' adolescents. A total of 13 adolescents (age 14.3+/-0.3 years; body mass index percentile 79+/-4 percentile; skipped breakfast 5+/-1 x per week) randomly completed 3 testing days that included a PN (18+/-1 g protein), PR (48+/-2 g protein) or BS. Breakfast was 24% of estimated daily energy needs. Appetite, satiety and hormonal responses were collected over 5 h followed by an ad libitum lunch and 24-h food intake assessments. Perceived appetite was not different following PN vs BS; PR led to greater reductions vs BS (PLunch energy intake was not different following PN vs BS; PR led to fewer kcal consumed vs BS (PDaily food intake was not different among treatments. Breakfast led to increased satiety through increased fullness and PYY concentrations in 'breakfast skipping' adolescents. A breakfast rich in dietary protein provides additional benefits through reductions in appetite and energy intake. These findings suggest that the addition of a protein-rich breakfast might be an effective strategy to improve appetite control in young people.

    a healthy breakfast is the one that includes a balanced portion of every nutrient qualitatively and quantitatively. Although it should supply the 20-25% calories of the day, it is usually insufficient or even absent. to study the food habits of schoolchildren and to participate in a health educational intervention of a Pharmaceutical Care Program with them. only the 36.6% of students have a healthy breakfast every day. The health education achieves favorable changes in the behavior and opinions of the schoolchildren participating. the percentage of students that have C group food is higher than in other studies. We can consider the fact that the School is located in a rural area with many vegetable gardens, and that can help students to eat more fruits. Another remarkable data is that the percentage of alumni that achieve a healthy breakfast is also higher than in other researchers. the breakfast of students of Fifth and Six Degree of Primary School is imbalanced. Health education by an educative and practical intervention benefits positive changes in the students' breakfast. It supports the effort of promoting Heath Education in Primary Schools.

    Very little is known about the differences in breakfast of children performing physical activity in the morning. This paper analyzed the breakfast habits of 747 boys and 455 girls, distributed in 2 homogeneous age groups, 6-10 and 11-14 year-old, participating in a Summer Sport School. Children were asked whether, when, where, how and with whom they consumed breakfast; who prepared meals; what they ate and drank; what they did during breakfast. Weight, height and BMI were recorded. Seventy-eight percent of children usually had breakfast, but 22% reported skipping breakfast. In the non-breakfast consumer subjects, 27.5% were overweight and 9.6% obese vs 9.1 and 4.5% respectively in breakfast eaters. Bakery products (76%) and milk (71%) were the most frequently consumed foods. Only 15% of parents encouraged their children to consume additional foods at breakfast before exercising, and 42% of children believed that this extra nutrition was unnecessary. In 80% of cases, the chief decision-maker for breakfast was the mother, the father played little part (1%). During breakfast, 48% of children ate and drank in silence, 26% played with brothers and sisters, 18% watched television and only 8% talked with parents. A high prevalence of over-weight and obesity was found among non-breakfast consumer children. Breakfast omission in children exercising conflicts with their increased energy requirements and may be connected to the trend of parents and children to under-estimate the importance of breakfast for nutritional balance and for environment promotion of physical performance.

    Breakfast has been labeled the most important meal of the day, but are there data to support this claim? We summarized the results of 47 studies examining the association of breakfast consumption with nutritional adequacy (nine studies), body weight (16 studies), and academic performance (22 studies) in children and adolescents. Breakfast skipping is highly prevalent in the United States and Europe (10% to 30%), depending on age group, population, and definition. Although the quality of breakfast was variable within and between studies, children who reported eating breakfast on a consistent basis tended to have superior nutritional profiles than their breakfast-skipping peers. Breakfast eaters generally consumed more daily calories yet were less likely to be overweight, although not all studies associated breakfast skipping with overweight. Evidence suggests that breakfast consumption may improve cognitive function related to memory, test grades, and school attendance. Breakfast as part of a healthful diet and lifestyle can positively impact children's health and well-being. Parents should be encouraged to provide breakfast for their children or explore the availability of a school breakfast program. We advocate consumption of a healthful breakfast on a daily basis consisting of a variety of foods, especially high-fiber and nutrient-rich whole grains, fruits, and dairy products.

    Breakfast is recommended as part of a healthy diet because it is associated with healthier macro- and micronutrient intakes, BMI and lifestyle. Breakfast is also widely promoted to improve cognitive function and academic performance, leading to the provision of breakfast initiatives by public health bodies. Despite this positive and intuitive perception of cognitive benefits, there has been no systematic review of the evidence. Systematic review methodology was employed to evaluate the effects of breakfast on cognitive performance in well-nourished children and nutritionally at-risk or stunted children. Acute experimental studies, school feeding programmes and studies of habitual breakfast intake are reviewed. Comparisons of breakfast v. no breakfast and breakfasts differing in energy and macronutrient composition are discussed. Included are forty-five studies described in forty-one papers published between 1950 and 2008. The evidence indicates that breakfast consumption is more beneficial than skipping breakfast, but this effect is more apparent in children whose nutritional status is compromised. There is a lack of research comparing breakfast type, precluding recommendations for the size and composition of an optimal breakfast for children's cognitive function. Few studies examined adolescents. Studies of school breakfast programmes suggest that such interventions can have positive effects on academic performance, but this may be in part explained by the increased school attendance that programmes encourage. The present systematic review considers methodological issues in this field and makes recommendations for future research design and policy priorities.

    The aim of the present study was to attempt to replicate and extend a recent result which showed that breakfast cereal consumption was associated with better mental health. The general population sample studied here (262 volunteers aged between 21 and 85 years, mean age: 60.9 years) was older than the sample in the previous study. The results showed that those who consumed breakfast cereal every day reported better mental and physical health than those who consumed it less frequently. This association was still present when demographic factors, indicators of lifestyle, such as smoking, or other aspects of diet were covaried. Further research is now required to elucidate the mechanisms underlying this robust association between daily breakfast cereal consumption and well-being.

  16. Can the provision of breakfast benefit school performance?

    Grantham-McGregor, Sally

    2005-06-01

    Studies of an association between school performance (enrollment, attendance, achievement, classroom behavior, and school drop-out) and nutritional status are discussed and the evidence of an effect of school meals evaluated. Many studies have shown associations between hunger, poor dietary intakes, stunting, underweight, and poor school performance after controlling for socioeconomic conditions. However, it remains possible that unmeasured socioeconomic variables could explain the relationship. Rigorous short-term studies of missing breakfast have generally found detrimental effects on children's cognition whereas studies of providing breakfast have shown benefits particularly in malnourished children. Classroom conditions may modify the effects of breakfast on behavior. There are extremely few longer term studies of the effects of giving school meals. Nearly all involved breakfast and very few had randomized controlled designs. Studies comparing participants with non-participants or comparing matched schools have found benefits (but bias due to self-selection) of receiving breakfast; inadequate matching of schools also remains possible. One longer term randomized controlled trial found benefits associated with attendance and arithmetic performance. In conclusion, most studies of giving breakfast have found benefits to school performance but many had serious design problems, were short-term, and were not conducted in the poorest countries. In order to advise policy makers correctly, there is an urgent need to run long-term randomized controlled trials of giving school meals in poor countries and to determine the effects of age and nutrition status of the children, the quality of the school, and the timing of the meal. The special needs of orphans should also be considered.

    Breakfast consumption has been shown to be an important indicator of a healthy lifestyle. Little is known however about factors influencing breakfast consumption and food choices at breakfast in adolescents. The aim of the present study was therefore to describe breakfast habits, and factors influencing food choices at breakfast within the framework of the EU-funded HELENA Study, in 3528 adolescents from ten European cities. Additionally, socio-demographic differences in breakfast habits and in influencing factors were investigated. Half of the adolescents (and fewer girls than boys) indicated being regular breakfast consumers. Girls with mothers with a high level of education, boys from 'traditional' families and boys who perceived low family affluence were positively associated with breakfast consumption. Boys whose parents gave encouragement and girls whose peers ate healthily were more likely to be regular breakfast consumers. 'Hunger', 'taste', 'health concerns' and 'parents or guardian' were the most important influences on the adolescents' food choices at breakfast. Adolescents from southern Europe and girls reported to be more influenced by personal and socio-environmental factors. Socio-demographic differences, in particular regional and gender differences, need to be considered in discussions surrounding the development of nutritional intervention programs intended for adolescents.

    The evolution of small magnetic features in quiet regions of the Sun provides a unique window for probing solar magneto-convection. Here we analyze small-scale magnetic features in the quiet Sun, using the high resolution, seeing-free observations from the Sunrise balloon borne solar observatory. Our aim is to understand the contribution of different physical processes, such as splitting, merging, emergence and cancellation of magnetic fields to the rearrangement, addition and removal of magnetic flux in the photosphere. We have employed a statistical approach for the analysis and the evolution studies are carried out using a feature-tracking technique. In this paper we provide a detailed description of the feature-tracking algorithm that we have newly developed and we present the results of a statistical study of several physical quantities. The results on the fractions of the flux in the emergence, appearance, splitting, merging, disappearance and cancellation qualitatively agrees with other recent studies. To summarize, the total flux gained in unipolar appearance is an order of magnitude larger than the total flux gained in emergence. On the other hand, the bipolar cancellation contributes nearly an equal amount to the loss of magnetic flux as unipolar disappearance. The total flux lost in cancellation is nearly six to eight times larger than the total flux gained in emergence. One big difference between our study and previous similar studies is that, thanks to the higher spatial resolution of Sunrise, we can track features with fluxes as low as 9 × 1014 Mx. This flux is nearly an order of magnitude lower than the smallest fluxes of the features tracked in the highest resolution previous studies based on Hinode data. The area and flux of the magnetic features follow power-law type distribution, while the lifetimes show either power-law or exponential type distribution depending on the exact definitions used to define various birth and death events.

    Full Text Available Most studies showing that children consuming breakfast have better nutrient intakes, diet quality, and lower weight than breakfast skippers have the incorrect premise that breakfast meals are homogeneous. The purpose of this study was to classify breakfast meals into patterns and determine the association of the breakfast patterns with daily and breakfast nutrient intakes, diet quality, and weight. Data from children (2-18 years of age; N = 14,200 participating in the National Health and Nutrition Examination Survey 2001-2008 were used. Intake was determined from one day 24-hour dietary recalls. Diet quality was measured using the Healthy Eating Index-2005 (HEI-2005. Body mass index (BMI z-scores were determined. Twelve patterns (including No Breakfast [~19% of population], explaining 63% of the variance in energy from breakfast, were examined. Covariate adjusted general linear models were used to compare outcome variables of consumers of different patterns with breakfast skippers. The p value was Bonferroni corrected (< 0.05/12 = < 0.0042. Consumers of the Eggs/Grain/Meat, Poultry, Fish (MPF/Fruit Juice (FJ and MPF/Grain/FJ patterns showed higher daily intakes of saturated fats, solid fats, and sodium and lower daily intakes of added sugars than breakfast skippers. Consumers of most breakfast patterns showed higher daily intakes of some nutrients of public health concern (dietary fiber, vitamin D, calcium, and potassium; however, those consuming the Grain or MPF/Grain/FJ pattern did not. Consumers of the Grain/Lower Fat Milk (LFM/Sweets/FJ, Presweetened (PS Ready-to-eat Cereal (RTEC/LFM, RTEC/LFM, Cooked Cereal/Milk/FJ, and Whole Fruit patterns had higher total HEI-2005 scores than breakfast skippers; those consuming the MPF/Grain/FJ pattern had lower diet quality than breakfast skippers.

    We have investigated a time series of continuum intensity maps and corresponding Dopplergrams of granulation in a very quiet solar region at the disk center, recorded with the Imaging Magnetograph eXperiment (IMaX) on board the balloon-borne solar observatory SUNRISE. We find that granules frequently show substructure in the form of lanes composed of a leading bright rim and a trailing dark edge, which move together from the boundary of a granule into the granule itself. We find strikingly similar events in synthesized intensity maps from an ab initio numerical simulation of solar surface convection. From cross sections through the computational domain of the simulation, we conclude that these granular lanes are the visible signature of (horizontally oriented) vortex tubes. The characteristic optical appearance of vortex tubes at the solar surface is explained. We propose that the observed vortex tubes may represent only the large-scale end of a hierarchy of vortex tubes existing near the solar surface.

    We characterize waves in small magnetic elements and investigate their propagation in the lower solar atmosphere from observations at high spatial and temporal resolution. We use the wavelet transform to analyze oscillations of both horizontal displacement and intensity in magnetic bright points found in the 300 nm and the Ca ii H 396.8 nm passbands of the filter imager on board the Sunrise balloon-borne solar observatory. Phase differences between the oscillations at the two atmospheric layers corresponding to the two passbands reveal upward propagating waves at high frequencies (up to 30 mHz). Weak signatures of standing as well as downward propagating waves are also obtained. Both compressible and incompressible (kink) waves are found in the small-scale magnetic features. The two types of waves have different, though overlapping, period distributions. Two independent estimates give a height difference of approximately 450 ± 100 km between the two atmospheric layers sampled by the employed spectral bands. This value, together with the determined short travel times of the transverse and longitudinal waves provide us with phase speeds of 29 ± 2 km s −1 and 31 ± 2 km s −1 , respectively. We speculate that these phase speeds may not reflect the true propagation speeds of the waves. Thus, effects such as the refraction of fast longitudinal waves may contribute to an overestimate of the phase speed.

    2017-03-01

    Background: Mexico has experienced shifts in food availability and consumption patterns over the past few decades from traditional diets to those containing more high-energy density foods, resulting in the development of unhealthful dietary patterns among children and adults. However, to our knowledge it is not known whether breakfast consumption patterns contribute to the overall daily diet of Mexican children. Objective: We examined total-day diet among breakfast consumers compared with breakfast skippers, identified and investigated breakfast dietary patterns in relation to energy and nutrient intakes at breakfast and across the day, and examined these patterns in relation to sociodemographic characteristics. Methods: With the use of nationally representative dietary data (one 24-h recall) from the 2012 Mexican National Health and Nutrition Survey, 3760 children aged 4-13 y were categorized into mutually exclusive breakfast patterns with the use of cluster analysis. The association between breakfast patterns and breakfast skippers with dietary intake at breakfast and for the total day was investigated with the use of multivariate linear regression. Results: Most children (83%) consumed breakfast. Six breakfast dietary patterns were identified (milk and sweetened breads, tortillas and beans, sweetened beverages, sandwiches and quesadillas, eggs, and cereal and milk) and reflected both traditional and more Westernized dietary patterns. Sugar-sweetened beverages were consumed across all patterns. Compared with all breakfast dietary patterns, breakfast skippers had the lowest intake of several nutrients of public health concern. Nutrients to limit that were high at breakfast tended to be high for the total day and vice versa for nutrients to encourage. Conclusions: There was not a single pattern that complied perfectly with the Mexican School Breakfast Guidelines, but changes such as increasing dietary fiber by encouraging more whole grains, fruits, vegetables, and

    With the creation of Mount Rainier National Park (MORA) in 1899 came the active management of the park's landscapes and a heavy emphasis on fire suppression. Today, managers at MORA seek to better manage current fire activity; however, this requires an improved understanding of past fire activity on the mountain. In this study high-resolution macroscopic charcoal analysis and pollen analysis of lake sediment records was used to reconstruct the postglacial fire and vegetation history for the Sunrise Ridge area of MORA. Fire activity was lowest during the Late Glacial when vegetation was sparse and climate was cool and dry. Fire activity increased during the early Holocene as the regional climate warmed and dried, and burnable biomass became more abundant. Fire activity continued to increase into the middle Holocene (until ca. 6600 cal yr BP) even as the regional climate became wetter and eventually cooler; the modern-day mesic forest and subalpine meadow landscapes of the park established at this time. Fire activity was generally highest and mean fire return intervals were lowest on Sunrise Ridge during the late Holocene, and are consistent with tree-ring based estimates of fire frequency. The similarity between the Sunrise Ridge and other paleofire records in the Pacific Northwest suggests that broad-scale climatic shifts, such as the retreat of the Cordilleran ice sheet and changes in annual insolation, as well as increased interannual climate variability (i.e., drought) particularly in the middle to late Holocene, were responsible for changes in fire activity during the postglacial period. However, abundant and increasing archaeological evidence from Sunrise Ridge during the middle to late Holocene suggests that humans may have also influenced the landscape at this time. It is likely that fires will continue to increase at MORA as drought becomes a more frequent occurrence in the Pacific Northwest.

    2017-02-15

    Bread and breakfast cereals are a major constituents of the human diet, yet their Cr(VI) content is not known. Chromium(VI) was determined in these products by high resolution continuum source atomic absorption spectrometer (HR-CS AAS) after leaching Cr(VI) with 0.10molL(-1) Na2CO3. The results showed that 33-73% of total Cr (58.17±5.12μgkg(-1)-156.1±6.66μgkg(-1)) in bread exist as Cr(VI) and the highest total Cr content was found in brown bread. It was shown that Cr(III) is oxidized to Cr(VI) during toasting of bread. Chromium(VI) content in breakfast cereals ranged between 20.4±4μgkg(-1) and 470.4±68μgkg(-1). Therefore, it can be concluded that bread and breakfast cereals contains Cr(VI) which does not exceed maximum acceptable concentration (MAC) of 0.003mgkg(-1)bw(-1)day(-1) through daily consumption of half a bowl (65g) of breakfast cereal and four slices of toasted (122g) or untoasted bread (160g).

    Breakfast skipping increases during adolescence and is associated with lower levels of physical activity and weight gain. Theory-based interventions promoting breakfast consumption in adolescents report mixed findings, potentially because of limited research identifying which determinants to target. This study aimed to: (i) utilise the Theory of Planned Behaviour (TPB) to identify the relative contribution of attitudes (affective, cognitive and behavioural) to predict intention to eat breakfast and breakfast consumption in adolescents and (ii) determine whether demographic factors moderate the relationship between TPB variables, intention and behaviour. Questionnaires were completed by 434 students (mean 14±0.9 years) measuring breakfast consumption (0-2, 3-6 or 7 days), physical activity levels and TPB measures. Data were analysed by breakfast frequency and demographics using hierarchical and multinomial regression analyses. Breakfast was consumed everyday by 57% of students, with boys more likely to eat a regular breakfast, report higher activity levels and report more positive attitudes towards breakfast than girls (Pbehaviours (Pbehaviour relationship for girls. Findings confirm that the TPB is a successful model for predicting breakfast intentions and behaviours in adolescents. The potential for a direct effect of attitudes on behaviours should be considered in the implementation and design of breakfast interventions.

    Breakfast is an important source of micronutrients in the diet and its consumption has been linked to positive health outcomes. The present analysis investigated the contribution that breakfast cereals make to the nutrient intakes of the materially deprived (low income) UK population. Data for 3728 respondents aged 2 years and over from the UK Low Income Diet and Nutrition Survey (2003-2005) were analysed. Nutrient intakes of consumers and non-consumers of breakfast cereal were compared. Breakfast cereals were consumed by 49% of men, 58% of women, 80% of boys and 80% of girls, and median intakes were: 35, 25, 29 and 21 g/d, respectively. Consumers of breakfast cereals had higher intakes of thiamin, riboflavin, niacin, biotin, folate, vitamin B(6), vitamin B(12), iron and zinc than non-consumers. Breakfast cereal consumption was also related to higher intakes of calcium, attributable to higher milk consumption. The intake of wholegrain and high-fibre breakfast cereals was associated with a higher intake of non-starch polysaccharides. Intakes of niacin, biotin, calcium and zinc were higher but that of vitamin B(6) was lower among consumers of exclusively wholegrain and high-fibre breakfast cereals compared with consumers of other breakfast cereals. There were no significant differences observed in intakes of non-milk extrinsic sugars according to type of breakfast cereal consumed. Breakfast cereals make a significant contribution to the micronutrient intake of the low-income UK population.

    Intiful, F D; Lartey, A

    2014-06-01

    Breakfast is considered the most important meal of the day, yet many people skip breakfast. Studies indicate that school age children who regularly skip breakfast are not likely to concentrate in class, thus affecting school performance. This study determined the breakfast habits and nutrient contributions of the breakfast meal to the days' nutrient intake. A cross sectional study was conducted among school children (n=359) between the ages of 6-19 years in Manya Krobo in the Eastern Region of Ghana. Questionnaires were used to collect information on background characteristics and breakfast consumption habits. The 24-hour dietary recall method was used to obtain information on the children's food intake. T-test was used to compare differences between means of variables of breakfast consumers and skippers. About 85.5% of the children had breakfast on the day of interview. More boys (87.8%) consumed breakfast compared to the girls (83.1%). For those who skipped breakfast, lack of food at home or lack of no money (36.5%) was the main reason. Breakfast consumers had significantly higher energy and nutrient intakes than those who skipped breakfast (energy 2259 verses 1360 kcal, p-0.039; vitamin A 1534 verses 662 ug/RE, p=0.001; iron 22.9 verses 13.9 mg, p=0.017, zinc 9.9 verses 5.6 mg, p=0.034). The breakfast meal contributed between 32-41% of the day's energy intake, and between 30-47% of micronutrient intake. Encouraging breakfast consumption among school children is a way to ensure that they meet their daily nutrient and energy intakes.

    TO know the relationship between breakfast, from a qualitative perspective, and school performance. The study was performed in 141 students (70 males and 71 females) with ages ranging 12-13 years, of 1st grade of Mandatory Secondary Education (ESO) from an institute of Saragossa, by means of recalling the breakfast of the day before. Breakfast quality has been assessed according to criteria of the Kid study: GOOD QUALITY: contains at least one food from each one of dairy, cereals, or fruit groups. IMPROVABLE QUALITY: lacks one of the groups. INSUFFICIENT QUALITY: lacks two groups. POOR QUALITY: does not have breakfast. We considered that quality was improved only when a mid-morning snack with a different food from those taken with breakfast was added. Average mark at the end of the school year has been the criterion used to assess school performance. Statistical analysis of data gathered for the present study has been done with SPSS software. This analysis comprises descriptive and inferential statistics. For analysis of global significance between the differences the Analysis of Variance method has been applied, followed by post hoe tests with Bonferroni's and Turkey's methods to detect specific groups explaining global significance. Average mark systematically increases as breakfast quality increases from an average score of 5.63 in the group with poor quality breakfast to 7.73 average score in the group with a good quality breakfast. An analysis of variance has been performed to study the statistical significance of the mean differences between both groups. The outcomes yield significant global differences between groups (p value = 0.001), i.e., the average mark significantly varies according to breakfast quality. When pooled quality of breakfast and mid-morning snack is analyzed, the average mark systematically increases as breakfast-snack quality increases, from an average mark of 5,77 in the group with poor or insufficient quality up to 7.61 in the group with

    A recent analysis demonstrates that the Saturnian C ring and essential features of the B and A rings agrees with the plasma cosmogony approach with an accuracy of about 1% or even better. This starts a transition of cosmogony from speculation to real science. Based on the monographs by Alfven and Arrhenius on the evolution of the solar system a cosmogonic scenario is tentatively proposed. This outlines the evolution of an interstellar cloud and the formation of stars surrounded by solar nebulae under the combined action of gravitational and electromagnetic forces. Further, matter falling in from the solar nebula towards the sun is processed by newly clarified electromagnetic processes and a plasma-planetesimal transition (PPT) occurs. Planetesimals accrete to planets and around some of them the same process in miniature leads to the formation of satellites. Also the origin of comets is discussed. (author)

    Full Text Available Objective: this study aimed to evaluate the association of breakfast intake with cardiometabolic risk factors in a nationally-representative sample of Iranian pediatrics. Methods: the study participants considered of 5,625 school students aged 10-18 years, studied in the third survey of the national school-based surveillance system (CASPIAN-III. They were classified into three groups based on the number of days they ate breakfast: “regular breakfast eater” (6-7days/week, “often breakfast eater” (3-5days/week, and “seldom breakfast eater” (0-2 days/week. Metabolic syndrome (MetS was defined based on the Adult Treatment Panel III (ATP III criteria modified for the pediatric age group. Moreover, high total cholesterol, high low-density lipoprotein cholesterol (LDL-C and generalized obesity were included as other cardiometabolic risk factors. Multiple logistic regression analyses were used to evaluate the association between the breakfast intake category and cardiometabolic risk factors. Results: the number of subjects classified as “regular”, “often” and “seldom” breakfast eaters were 2,653(47.3%, 1,327(23.7% and 1,624(29.0%, respectively. The average of triglycerides (TG, LDL-C, systolic blood pressure (SBP and body mass index (BMI were higher in the “seldom breakfast eater” group (P for trend<0.001, whereas the mean of high-density lipoprotein cholesterol (HDL-C was lower in this group than their other counterparts. Seldom breakfast eaters had an increased risk of obesity, elevated TG and LDL-C, as well as low HDL-C compared to “regular breakfast eaters”. The risk of MetS was significantly increased in subjects who seldom ate breakfast (OR 1.96, 95% CI 1.18-3.27. Conclusions: skipping breakfast is associated with increased risk of MetS and other cardiometabooic factors in children and adolescents. Promoting the benefit of eating breakfast could be a simple and important implication to prevent these risk factors

    We present observations of transverse oscillations in slender Ca ii H fibrils (SCFs) in the lower solar chromosphere. We use a 1 hr long time series of high- (spatial and temporal-) resolution seeing-free observations in a 1.1 Å wide passband covering the line core of Ca ii H 3969 Å from the second flight of the Sunrise balloon-borne solar observatory. The entire field of view, spanning the polarity inversion line of an active region close to the solar disk center, is covered with bright, thin, and very dynamic fine structures. Our analysis reveals the prevalence of transverse waves in SCFs with median amplitudes and periods on the order of 2.4 ± 0.8 km s{sup −1} and 83 ± 29 s, respectively (with standard deviations given as uncertainties). We find that the transverse waves often propagate along (parts of) the SCFs with median phase speeds of 9 ± 14 km s{sup −1}. While the propagation is only in one direction along the axis in some of the SCFs, propagating waves in both directions, as well as standing waves are also observed. The transverse oscillations are likely Alfvénic and are thought to be representative of magnetohydrodynamic kink waves. The wave propagation suggests that the rapid high-frequency transverse waves, often produced in the lower photosphere, can penetrate into the chromosphere with an estimated energy flux of ≈15 kW m{sup −2}. Characteristics of these waves differ from those reported for other fibrillar structures, which, however, were observed mainly in the upper solar chromosphere.

    We characterize waves in small magnetic elements and investigate their propagation in the lower solar atmosphere from observations at high spatial and temporal resolution. We use the wavelet transform to analyze oscillations of both horizontal displacement and intensity in magnetic bright points found in the 300 nm and the Ca ii H 396.8 nm passbands of the filter imager on board the Sunrise balloon-borne solar observatory. Phase differences between the oscillations at the two atmospheric layers corresponding to the two passbands reveal upward propagating waves at high frequencies (up to 30 mHz). Weak signatures of standing as well as downward propagating waves are also obtained. Both compressible and incompressible (kink) waves are found in the small-scale magnetic features. The two types of waves have different, though overlapping, period distributions. Two independent estimates give a height difference of approximately 450 ± 100 km between the two atmospheric layers sampled by the employed spectral bands. This value, together with the determined short travel times of the transverse and longitudinal waves provide us with phase speeds of 29 ± 2 km s{sup −1} and 31 ± 2 km s{sup −1}, respectively. We speculate that these phase speeds may not reflect the true propagation speeds of the waves. Thus, effects such as the refraction of fast longitudinal waves may contribute to an overestimate of the phase speed.

    Breakfast cereals exhibit a wide variability in nutritional quality, and differences are not easily grasped by consumers. A simplified nutritional information system might contribute to help consumers make healthier food choices. A five-category colour label based on the Food Standards Agency Nutrient profiling system (FSA score) has been proposed in France to be implemented on the front-of-pack of foods (the five-colour nutrition label - 5-CNL). Objectives were to evaluate the ability of the 5-CNL to discriminate nutritional quality between types of breakfast cereals, within a category and in equivalent products, as well as its ability to change through product reformulation. Nutritional information was collected through an Internet and supermarket research for N = 433 breakfast cereals (N = 380 complete data included in the analyses). Breakfast cereals were categorized according to common attributes in terms of processing and/or ingredients used. The FSA score and 5-CNL category allocation were computed for each cereal. Nutrient content and FSA score were compared across types of cereals. Distribution within the 5-CNL categories was assessed across types of cereals and for equivalent products. Impact of reformulation (reduction of 5 and 10% in simple sugar, saturated fat and sodium) on the 5-CNL category allocation was compared to original allocation with Bapkhar's tests of homogeneity of marginal distribution. Variability in nutritional quality of breakfast cereals was high, as reflected by the FSA score (range -7- 22 for a theoretical range of -15-40) and the 5-CNL (all five categories represented). The 5-CNL allowed for discrimination across types of cereals, within categories of breakfast cereals and for equivalent products (at least 3 categories of the 5-CNL represented). Reformulation scenarios allowed for significant change in 5-CNL allocation: 5% reduction in sugar lead to a modification of the label for 4.21% of products while a reduction of 10

    The relationship between breakfast composition and cognitive performance was examined in elementary school children. Two experiments compared the effects of two common U.S. breakfast foods and no breakfast on children's cognition. Using a within-participant design, once a week for 3 weeks, children consumed one of two breakfasts or no breakfast and then completed a battery of cognitive tests. The two breakfasts were instant oatmeal and ready-to-eat cereal, which were similar in energy, but differed in macronutrient composition, processing characteristics, effects on digestion and metabolism, and glycemic score. Results with 9 to 11 year-olds replicated previous findings showing that breakfast intake enhances cognitive performance, particularly on tasks requiring processing of a complex visual display. The results extend previous findings by showing differential effects of breakfast type. Boys and girls showed enhanced spatial memory and girls showed improved short-term memory after consuming oatmeal. Results with 6 to 8 year-olds also showed effects of breakfast type. Younger children had better spatial memory and better auditory attention and girls exhibited better short-term memory after consuming oatmeal. Due to compositional differences in protein and fiber content, glycemic scores, and rate of digestion, oatmeal may provide a slower and more sustained energy source and consequently result in cognitive enhancement compared to low-fiber high glycemic ready-to-eat cereal. These results have important practical implications, suggesting the importance of what children consume for breakfast before school.

    To determine whether breakfast consumption or content affects academic achievement measured by standardized tests. Baseline data were collected in fall of 2011 from 698 students (50.5% female, age = 7.5 ± 0.6 years) living in the state of Kansas. Academic achievement was assessed using 3 components from the Wechsler Individual Achievement Test (WIAT-III). Prior to taking the WIAT-III, participants completed a breakfast recall of all foods and drinks consumed that morning, which was analyzed using Nutrition Data System for Research (NDS-R). WIAT-III scores were compared between breakfast and non-breakfast consumers in a sample (n = 162) matched for age, sex, race, education level of both parents, household income, body mass index (BMI), and cardiovascular fitness, and Pearson correlations were calculated from all breakfast eaters (n = 617) between test performance and components of the breakfast. When compared to non-breakfast consumers, the breakfast consumers had significantly higher scores in all 3 WIAT-III components (all p breakfast consumers, servings of fruit juice were negatively correlated with reading comprehension and fluency standard score and mathematics standard score (both p breakfast consumption and the content may be associated with improved standardized test performance in elementary school students.

    We tested the hypothesis that cessation of habitual ingestion of breakfast cereals would be associated with elevated plasma homocyst(e)ine concentrations. We anticipated that those subjects who reported consuming breakfast cereals containing 100 to 400 ,microg of folic acid per serving before entering the study would achieve higher plasma homocyst(e)ine concentrations if, in addition to their regular diet, they began ingesting a daily serving of breakfast cereal that contained less than 10 microg of folic acid per serving. Seventy-nine subjects consumed a daily serving of breakfast cereal containing either ine elevation. Breakfast cereal containing 200 microg folic acid per day was sufficient to maintain the homocyst(e)ine lowering effects of commercial cereals. Habitual consumption of commercially available fortified breakfast cereals, usually containing 100 to 400 microg folic acid per serving, had significant homocyst(e)ine lowering effects as shown by the homocyst(e)ine increase after cessation of habitual intake of commercial breakfast cereal. Substitution of breakfast cereal containing only 200 microg folic acid per day was sufficient to maintain the homocyst(e)inelowering effects of commercial cereals.

    Breakfast consumption has been consistently associated with health outcomes and cognitive functioning in schoolchildren. Evidence of direct links with educational outcomes remains equivocal. We aimed to examine the link between breakfast consumption in 9-11-year-old children and educational outcomes obtained 6-18 months later. Data on individual-level free school meal entitlement and educational outcomes (Statutory Assessment Tests (SATs) at Key Stage 2) were obtained via the SAIL databank and linked to earlier data collected on breakfast consumption. Multilevel modelling assessed associations between breakfast consumption and SATs. Trial of the Primary School Free Breakfast Initiative in Wales. Year 5 and 6 students, n 3093 (baseline) and n 3055 (follow-up). Significant associations were found between all dietary behaviours and better performance in SATs, adjusted for gender and individual- and school-level free school meal entitlement (OR=1·95; CI 1·58, 2·40 for breakfast, OR=1·08; CI 1·04, 1·13 for healthy breakfast items). No association was observed between number of unhealthy breakfast items consumed and educational performance. Association of breakfast consumption with educational performance was stronger where the measure of breakfast consumption was more proximal to SATs tests (OR=2·02 measured 6 months prior to SATs, OR=1·61 measured 18 months prior). Significant positive associations between self-reported breakfast consumption and educational outcomes were observed. Future research should aim to explore the mechanisms by which breakfast consumption and educational outcomes are linked, and understand how to promote breakfast consumption among schoolchildren. Communicating findings of educational benefits to schools may help to enhance buy-in to efforts to improve health behaviours of pupils.

    Breakfast consumption has been recommended as part of a healthy diet. Recently, ready-to-eat cereals (RTEC) became more popular as a breakfast item. Our aim was to analyse the dietary characteristics of an RTEC breakfast in European adolescents and to compare them with other breakfast options. From the European multi-centre HELENA study, two 24-h dietary recalls of 3137 adolescents were available. Food items (RTEC or bread, milk/yoghurt, fruit) and macro- and micronutrient intakes at breakfast were calculated. Cross-sectional regression analyses were adjusted for gender, age, socio-economic status and city. Compared to bread breakfasts (39 %) and all other breakfasts (41.5 %), RTEC breakfast (19.5 %) was associated with improved nutrient intake (less fat and less sucrose; more fibre, protein and some micronutrients like vitamin B, calcium, magnesium and phosphorus) at the breakfast occasion. Exceptions were more simple sugars in RTEC breakfast consumers: more lactose and galactose due to increased milk consumption, but also higher glucose and fructose than bread consumers. RTEC consumers had a significantly higher frequency (92.5 vs. 50.4 and 60.2 %) and quantity of milk/yoghurt intake and a slightly higher frequency of fruit intake (13.4 vs. 10.9 and 8.0 %) at breakfast. Among European adolescents, RTEC consumers showed a more favourable nutrient intake than consumers of bread or other breakfasts, except for simple sugars. Therefore, RTEC may be regarded as a good breakfast option as part of a varied and balanced diet. Nevertheless, more research is warranted concerning the role of different RTEC types in nutrient intake, especially for simple sugars.

    Universal access to the School Breakfast Program (SBP) is intended to help low-income and food-insecure students overcome barriers to eating breakfast. However, SBP participation is often still low despite universal access. Further information is needed with regard to these children's breakfast behaviors, and in particular breakfast behaviors among youth from food-insecure families, to inform effective breakfast interventions. The objective of this study was to examine breakfast behaviors among a large sample of urban students with universal access to the SBP and to identify differences in breakfast behaviors among children from food-secure compared with food-insecure households. A cross-sectional study of 821 fourth- through sixth-grade students and their parents from 16 schools was conducted. Students reported the foods/drinks selected and location of obtaining food/drink on the morning of data collection, parents reported household food security status using the 6-item Food Security Survey Module, and the school district provided SBP participation data during the fall semester of 2013. Multivariable linear regression models accounting for school-level clustering were used to examine differences in breakfast behaviors across 3 levels of household food security: food secure, low food secure, and very low food secure. Students participated in the SBP 31.2% of possible days, with 13% never participating in the SBP. One-fifth (19.4%) of students purchased something from a corner store for breakfast, and 16.9% skipped breakfast. Forty-six percent of students were food insecure; few differences in breakfast behaviors were observed across levels of food security. Despite universal access to the SBP, participation in the SBP is low. Breakfast skipping and selection of foods of low nutritional quality in the morning are common, regardless of household food security status. Additional novel implementation of the SBP and addressing students' breakfast preferences may be

    During the advanced stage of the Maillard reaction (MR) in food processing and cooking, Amadori rearrangement products undergo dehydration and fission and fluorescent substances are formed. Free and total (free + linked to the protein backbone) fluorescence (FIC) due to Maillard compounds in 60 commercial breakfast cereals was evaluated. Pronase was used for efficient release of linked fluorescent Maillard compounds from the protein backbone. Results were correlated with some heat-induced markers of the extent of the MR or sugar caramelisation during cereal processing, such as hydroxymethylfurfural, furfural, glucosilisomaltol and furosine. The effect of sample composition (dietary-fibre added, protein, etc.) on levels of FIC, expressed as fluorescence intensity (FI) per milligram of sample, is discussed. FIC is significantly correlated to the protein content of the sample and fluorescent Maillard compounds are mainly linked to the protein backbone. The ratio of total-FIC to free-FIC was 10.4-fold for corn-based, wheat-based and multicereal-based breakfast cereals but significantly higher in rice-based samples. Addition of dietary fibre or honey increased the FIC values. Data support the usefulness of FIC measurement as an unspecific heat-induced marker in breakfast cereals.

    This functional magnetic resonance imaging (fMRI) pilot study identified whether breakfast consumption would alter the neural activity in brain regions associated with food motivation and reward in overweight "breakfast skipping" (BS) adolescent girls and examined whether increased protein at breakfast would lead to additional alterations. Ten girls (Age: 15 ± 1 years; BMI percentile 93 ± 1%; BS 5 ± 1×/week) completed 3 testing days. Following the BS day, the participants were provided with, in randomized order, normal protein (NP; 18 ± 1 g protein) or higher protein (HP; 50 ± 1 g protein) breakfast meals to consume at home for 6 days. On day 7 of each pattern, the participants came to the laboratory to consume their respective breakfast followed by appetite questionnaires and an fMRI brain scan to identify brain activation responses to viewing food vs. nonfood images prior to lunch. Breakfast consumption led to enduring (i.e., 3-h post breakfast) reductions in neural activation in the hippocampus, amygdala, cingulate, and parahippocampus vs. BS. HP led to enduring reductions in insula and middle prefrontal cortex activation vs. NP. Hippocampal, amygdala, cingulate, and insular activations were correlated with appetite and inversely correlated with satiety. In summary, the addition of breakfast led to alterations in brain activation in regions previously associated with food motivation and reward with additional alterations following the higher-protein breakfast. These data suggest that increased dietary protein at breakfast might be a beneficial strategy to reduce reward-driven eating behavior in overweight teen girls. Due to the small sample size, caution is warranted when interpreting these preliminary findings.

    Bright points (BPs) in the solar photosphere are thought to be the radiative signatures (small-scale brightness enhancements) of magnetic elements described by slender flux tubes or sheets located in the darker intergranular lanes in the solar photosphere. They contribute to the ultraviolet (UV) flux variations over the solar cycle and hence may play a role in influencing the Earth's climate. Here we aim to obtain a better insight into their properties by combining high-resolution UV and spectro-polarimetric observations of BPs by the Sunrise Observatory with 3D compressible radiation magnetohydrodynamical (MHD) simulations. To this end, full spectral line syntheses are performed with the MHD data and a careful degradation is applied to take into account all relevant instrumental effects of the observations. In a first step it is demonstrated that the selected MHD simulations reproduce the measured distributions of intensity at multiple wavelengths, line-of-sight velocity, spectral line width, and polarization degree rather well. The simulated line width also displays the correct mean, but a scatter that is too small. In the second step, the properties of observed BPs are compared with synthetic ones. Again, these are found to match relatively well, except that the observations display a tail of large BPs with strong polarization signals (most likely network elements) not found in the simulations, possibly due to the small size of the simulation box. The higher spatial resolution of the simulations has a significant effect, leading to smaller and more numerous BPs. The observation that most BPs are weakly polarized is explained mainly by the spatial degradation, the stray light contamination, and the temperature sensitivity of the Fe i line at 5250.2 Å. Finally, given that the MHD simulations are highly consistent with the observations, we used the simulations to explore the properties of BPs further. The Stokes V asymmetries increase with the distance to the

    A new class of identities for Feynman graph amplitudes, dubbed Schouten identities, valid at fixed integer value of the dimension d is proposed. The identities are then used in the case of the two-loop sunrise graph with arbitrary masses for recovering the second-order differential equation for the scalar amplitude in d=2 dimensions, as well as a chained set of equations for all the coefficients of the expansions in (d−2). The shift from d≈2 to d≈4 dimensions is then discussed

    Besides genetic and environmental factors, the breakfast meal and the frequency in which it is eaten may influence appetite control, dietary intake and composition, and chronic disease risk. Breakfast skipping may lead to up-regulation of appetite, possibly leading to weight gain over time and deleterious changes in risk factors for diabetes and cardiovascular disease. Breakfast skipping has also been linked to poorer overall diet quality. Regular breakfast consumption, on the other hand, may reduce the risk of chronic diseases due to the potential impact on the composition of the overall diet, and is also associated with improved learning abilities and better school performance in children. Considering the trend to skip, or to have nutritionally inadequate breakfast, suggestions to promote and support breakfast in children and adolescents will be considered.

    The goal of this study is to study optimized satellite configurations for observation of the radiation balance of the earth. We present a literature survey of earth radiation budget missions and instruments. We develop a parametric tool to simulate realistic multiple satellite mission scenarios. This tool is a modular computer program which models satellite orbits and scanning operation. We use Meteosat data sampled at three hour intervals as a database to simulate atmospheric scenes. Input variables are satellite equatorial crossing time and instrument characteristics. Regional, zonal and global monthly averages of shortwave and longwave fluxes for an ideal observing system and several realistic satellite scenarios are produced. Comparisons show that the three satellite combinations which have equatorial crossing times at midmorning, noon and midafternoon provide the best shortwave monitoring. Crossing times near sunrise and sunset should be avoided for the shortwave. Longwave diurnal models are necessary over and surfaces and cloudy regions, if there are only two measurements made during daylight hours. We have found in the shortwave inversion comparison that at least 15% of the monthly regional errors can be attributed to the shortwave anisotropic models used. (orig.) 68 refs.

    Breakfast consumption is associated with positive outcomes for diet quality, micronutrient intake, weight status and lifestyle factors. Breakfast has been suggested to positively affect learning in children in terms of behavior, cognitive, and school performance. However, these assertions are largely based on evidence which demonstrates acute effects of breakfast on cognitive performance. Less research which examines the effects of breakfast on the ecologically valid outcomes of academic performance or in-class behavior is available. The literature was searched for articles published between 1950-2013 indexed in Ovid MEDLINE, Pubmed, Web of Science, the Cochrane Library, EMBASE databases, and PsychINFO. Thirty-six articles examining the effects of breakfast on in-class behavior and academic performance in children and adolescents were included. The effects of breakfast in different populations were considered, including undernourished or well-nourished children and adolescents from differing socio-economic status (SES) backgrounds. The habitual and acute effects of breakfast and the effects of school breakfast programs (SBPs) were considered. The evidence indicated a mainly positive effect of breakfast on on-task behavior in the classroom. There was suggestive evidence that habitual breakfast (frequency and quality) and SBPs have a positive effect on children's academic performance with clearest effects on mathematic and arithmetic grades in undernourished children. Increased frequency of habitual breakfast was consistently positively associated with academic performance. Some evidence suggested that quality of habitual breakfast, in terms of providing a greater variety of food groups and adequate energy, was positively related to school performance. However, these associations can be attributed, in part, to confounders such as SES and to methodological weaknesses such as the subjective nature of the observations of behavior in class.

    Breakfast skipping is associated with obesity and an increased risk of type 2 diabetes. Later chronotypes, individuals who have a preference for later bed and wake times, often skip breakfast. The aim of the study was to explore the relationships among breakfast skipping, chronotype, and glycemic control in type 2 diabetes patients. We collected sleep timing and 24-h dietary recall from 194 non-shift-working type 2 diabetes patients who were being followed in outpatient clinics. Mid-sleep time on free days (MSF) was used as an indicator of chronotype. Hemoglobin A1C (HbA1C) values were obtained from medical records. Hierarchical linear regression analyses controlling for demographic, sleep, and dietary variables were computed to determine whether breakfast skipping was associated with HbA1C. Additional regression analyses were performed to test if this association was mediated by chronotype. There were 22 participants (11.3%) who self-reported missing breakfast. Breakfast skippers had significantly higher HbA1C levels, higher body mass indices (BMI), and later MSF than breakfast eaters. Breakfast skipping was significantly associated with higher HbA1C values (B = 0.108, p = 0.01), even after adjusting for age, sex, race, BMI, number of diabetes complications, insulin use, depressive symptoms, perceived sleep debt, and percentage of daily caloric intake at dinner. The relationship between breakfast skipping and HbA1C was partially mediated by chronotype. In summary, breakfast skipping is associated with a later chronotype. Later chronotype and breakfast skipping both contribute to poorer glycemic control, as indicated by higher HbA1C levels. Future studies are needed to confirm these findings and determine whether behavioral interventions targeting breakfast eating or sleep timing may improve glycemic control in patients with type 2 diabetes.

The rationale for this approach was that the beneficial effects of any intervention with regard to cognitive function may be more readily apparent when more demands are placed on the system. Furthermore, as skipping breakfast is particularly prevalent within this age group, thus, we ...

    Elderly people are becoming more prevalent in our country, which studies in this group are relevant. Moreover, the health impact of breakfast consumption is demonstrated in school groups. To determine whether breakfast consumption is associated with better quality of life in self-sufficient Chilean elderly. We interviewed 1,285 elderly (> 60 years) of both sexes. We applied two surveys (food and healthy lifestyles surveys), then an anthropometric evaluation was conducted. 5.6% of older adults does not consume breakfast. Those who consume breakfast had a better quality of life (p = 0.004), specifically in men breakfast intake is associated with lower body mass index (BMI) (p=0.002). Moreover, the results indicate that the proportion of elderly who smokes and does not take breakfast is higher, as well as, greater responsibility in health, nutrition, stress management are greater in those that take breakfast. Finally there was an association between breakfast consumption and better nutrition (p = 0.01) and self-realization (p = 0.005).

    The objective of this study was to examine the effect of self-reported breakfast size, daily eating, and other health habits on body mass index (BMI). We hypothesized that a consumption of a substantial breakfast compared with skipping or small breakfasts would be associated with lower BMI. Three independent, cross-sectional, screening surveys were conducted by Sydney Adventist Hospital in 1976, 1986, and 2005 in the surrounding community. The archived survey forms of 384 men and 338 women in 1976, 244 men and 229 women in 1986, and 270 men and 62 women in 2005 were randomly selected. Body mass index was determined from height and weight measured by hospital staff. The reported amount consumed at breakfast was one of several eating habits that predicted BMI for men but not women. It explained 5% to 6% of the variance in male BMI in all 3 years examined. As the reported breakfast amount increased, men's BMI decreased. Lifestyle confounders including vegetarianism and physical activity did not affect this relationship. However, the consumption of breakfast was significantly positively associated with consumption of cereals, bread, fruit, and spreads, while coffee consumption was significantly associated with smaller breakfasts or breakfast skipping. The consumption of relatively large breakfasts may influence BMI in men, and its promotion may help reduce the prevalence of obesity in Australia and elsewhere. Copyright 2010 Elsevier Inc.

    Breakfast consumption has been associated with better mental health in adulthood, but the relationship between breakfast and mental health in adolescence is less well known. The aims of the present study were to evaluate breakfast quality in a cohort of adolescents and to investigate associations with mental health. Cross-sectional population-based study. Breakfast quality was assessed by intake of core food groups at breakfast, as determined from 3 d food diaries. Mental health was assessed using the Child Behaviour Checklist (CBCL), with higher scores representing poorer behaviour. The Western Australian Pregnancy Cohort (Raine) Study, Perth, Western Australia. Eight hundred and thirty-six males and females aged between 13 and 15 years. Mean mental health score as assessed by the CBCL was 45.24 (sd 11.29). A high-quality breakfast consisting of at least three food groups was consumed by 11 % of adolescents, while 7 % of adolescents did not consume any items from core food groups on average over the 3 d period. The two most common core food groups consumed at breakfast in this population were dairy products followed by breads and cereals. For every additional food group eaten at breakfast, the associated total mental health score decreased by 1.66 (95 % CI -2.74, -0.59) after adjustment for potential confounding factors, representing an improvement in mental health score. These findings support the concept that breakfast quality is an important component in the complex interaction between lifestyle factors and mental health in early adolescence.

    Previous studies suggest skipping breakfast is associated with lower diet quality, but possible reasons underlying this relationship are not clear. Our aim was to determine the relationship between chronic stress and variations in diet quality in the context of breakfast eating or breakfast skipping. Based on morning eating habits, 40 breakfast eaters and 35 breakfast skippers participated in a cross-sectional study. Diet assessment was based on unannounced 24-hour recalls. Women, ages 18 to 45 years, with a body mass index (calculated as kg/m 2 ) Healthy Eating Index 2010 (HEI-2010). Stress and executive function were evaluated with validated questionnaires and a computer-based task, respectively. Diet characteristics of breakfast eating and breakfast skipping were evaluated as nutrient densities (amounts per 1,000 kcal) and compared using a one-way analysis of covariance, with body mass index as covariate. Diet and stress variable associations were assessed using Pearson correlations. Despite no observed differences in daily energy intake between breakfast skipping and breakfast eating, overall diet quality (P=0.001), whole grains (P=0.002), fruit (P=0.002), empty calories (P=0.050), fiber (P=0.001), calcium (P=0.001), potassium (P=0.033), and folate (P=0.013) intakes were higher in breakfast eating. In the evening, breakfast skipping consumed more added sugars (P=0.012) and saturated fat (P=0.006). In breakfast skipping, reported stress was associated with empty calories (r=-0.39; P=0.027) and evening intake of added sugars (r=0.501; P=0.005). These relationships were not observed in breakfast eating. Breakfast skippers were less likely to meet the Dietary Guidelines for Americans and consumed more empty calories at night. Chronic stress was related to evening eating choices and overall empty calories in the diet of breakfast skippers, whereas breakfast eaters' dietary intake did not appear to be affected by chronic stress.

    Breakfast skipping is a potentially modifiable behavior that has negative effects on health and is socioeconomically patterned. This study aimed to examine the intrapersonal (health, behavioral, and cognitive) and social factors associated with breakfast skipping. Nonpregnant women (n = 4123) aged 18-45 y from socioeconomically disadvantaged neighborhoods throughout Victoria, Australia, completed a postal questionnaire. Sociodemographic characteristics, diet, physical activity, sedentary behaviors, and cognitive and social factors were assessed by self-report. Breakfast skipping was defined in 2 ways: 1) "rarely/never" eating breakfast (n = 498) and 2) eating breakfast ≤2 d/wk (includes those who rarely/never ate breakfast; n = 865). Poisson regression was used to calculate prevalence ratios and linear trends, adjusting for covariates. The P values for linear trends are reported below. Compared with breakfast consumers, women who reported rarely/never eating breakfast tended to have poorer self-rated health (P-trend pay less attention to health (P-trend lower proportion were trying to control their weight (P-trend lower leisure-time physical activity (P-trend = 0.012) and less self-efficacy for eating a healthy diet (P-trend women living in socioeconomically disadvantaged areas. Acknowledging the cross-sectional design and need for causal confirmation, programs that aim to promote breakfast consumption in this population group should consider targeting family-related barriers to healthy eating and nutrition knowledge.

    The effect of different breakfast consumption patterns on nutrient intake, diet quality, and weight/adiposity status is unknown. To compare nutrient intake, diet quality, and weight/adiposity measures of consumers assigned to different breakfast patterns with breakfast skippers. These associations were assessed in adults 19+ years (N=18,988) participating in the 2001-2008 National Health and Nutrition Examination Survey. Intake was determined from 1-day 24-hour dietary recall. Diet quality was quantified using the Healthy Eating Index-2005. Body mass index (calculated as kg/m(2)) and waist circumferences were determined. Twelve patterns (including No Breakfast [approximately 19% of population]), explaining 58% of the variance in energy from the breakfast meal, were examined. Covariate adjusted general linear models were used to compare nutrient intakes, Healthy Eating Index-2005 scores, and body mass index/waist circumference of consumers of different patterns with breakfast skippers. The P value was Bonferroni corrected (Juice and Presweetened Ready-to-Eat Cereal (RTEC)/Lower-Fat Milk patterns had lower daily intakes of nutrients to limit (added sugars, saturated fatty acids, solid fats, cholesterol, and sodium) than breakfast skippers.

    Breakfast provides the necessary energy and nutrients to achieve an optimal physical and mental performance. OBJECTIVE. To find out breakfast frequency, factors that influence breakfast habit and skipping, breakfast quality and snack intake in children from public schools in the city of Santa Fe. POPULATION AND METHODS. Descriptive, cross-sectional study. A total of 637 students were assessed using a closed-ended question survey. RESULTS. Seventy five percent of children had breakfast on a daily basis; only 1.6% had a good quality breakfast. Eating breakfast every day or some days did not depend on having the company of a family member. In the case of first to fifth grade children, the weekly frequency depended on having a family member who made it (p= 0.04). The main cause for skipping breakfast was lack of time. Twenty-three percent of children in sixth and seventh grade indicated feeling unwell when having breakfast. More than 50% of children watched television while having breakfast. Most students in first to third grade had breakfast that could be improved (41%) and which was insufficient (41%). An insufficient quality breakfast was more common among fourth and fifth grade students (50%). A remarkable piece of information is the number of sixth and seventh grade children who had a poor quality breakfast (16%). Very few children had a snack that was appropriate to supplement the final quality of breakfast. CONCLUSIONS. Although a high percentage of school-aged children are used to having breakfast, most have an incomplete breakfast. Very few manage to supplement their breakfast with snacks at mid-morning.

    The current study assessed the interactive effect of breakfast and exercise on cognition and mood. Twelve active males completed four trials; no breakfast-rest, breakfast-rest, no breakfast-exercise or breakfast-exercise in a randomized, cross-over design. The trials consisted of; breakfast or fast, a 2h rest, exercise (treadmill run) or equivalent rest, a chocolate milk drink, a 90 min rest and an ad libitum lunch. Cognitive performance and mood were recorded frequently throughout each trial. Data was analysed as pre-exercise/rest, during and immediately post exercise/rest and post-drink. No effects were found prior to consumption of the drink. Post-drink, fasting before exercise increased mental fatigue compared to consuming breakfast before exercise and fasting before rest. Tension increased when breakfast was consumed at rest and when exercise was undertaken fasted compared to omitting breakfast before rest. Breakfast before rest decreased rapid visual information processing task speed and impaired Stroop performance. Breakfast omission improved Four Choice Reaction Time performance. To conclude, breakfast before exercise appeared beneficial for post-exercise mood even when a post-exercise snack was consumed. Exercise reversed post-breakfast cognitive impairment in active males.

    School breakfast consumption can improve children's nutrition, but the implications of breakfast at school for children's weight remains unclear. The aim of this study was to determine whether receiving breakfast at school is related to changes in children's weight between the fifth and eighth grades, and whether the relationship between school breakfasts and obesity varies for children of different socioeconomic backgrounds. This was a longitudinal study of children observed in the fifth and eighth grades. Data are from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99, a nationally representative prospective cohort of children in the United States. The analytic sample consisted of 6,495 children interviewed in the fifth and eighth grades. Standard thresholds from the Centers for Disease Control and Prevention were used to classify children as not obese or obese based on direct-measured height and weight. Difference-in-difference propensity score matching and fixed-effect logistic regression models were used to estimate the relationship between receipt of school breakfast and change in obesity between the fifth and eighth grades, adjusting for child, household, and school characteristics. School breakfast receipt was not associated with a change in obesity status between the fifth and eighth grades for children overall (odds ratio=1.31; P=0.129). In the propensity score model, receiving school breakfasts more than doubled the odds of becoming obese (odds ratio=2.31; P=0.0108) for children from families below the federal poverty line compared with children of similar socioeconomic backgrounds who did not regularly receive school breakfasts. School breakfast receipt was not independently related to obesity for most children. Receiving school breakfasts in the fifth grade may be associated with weight gain between the fifth and eighth grades for children from families below the federal poverty line compared with children of similar socioeconomic

    The cognitive and behavioural effects of a school breakfast were explored in a study of 55 children in Grade II and Standard 1 at a farm school outside Johannesburg. A previous study had confirmed widespread undernutrition and micronutrient deficiencies among the children. For comparative purposes, 55 children at an inner-city school, among whom no signs of undernutrition were found, were assessed in the same way. Three different types of measures of attention, distractibility, short-term memory and activity level were used: psychometric testing of the children; teacher ratings of children's classroom behaviour, and coded video-recorded classroom behaviour. A pre- and post-test design was employed to assess the effects of a school breakfast, continually in place in the experimental school for a period of 6 weeks. The results indicated significant change from pre- to post-test assessment among the experimental children in respect of the psychometric measures, teacher-rated hyperactivity and video-recorded classroom behaviour. With regard to the latter measure, the children showed a decline in both the occurrence and duration of off-task and out-of-seat behaviour, and an increase in active participation in class and positive peer interaction. While the children in the comparison group also showed some changes from pre- to post-test, probably attributable to the effects of observation, familiarity with the test materials and developmental change, the changes were not generalised or consistent. The findings support the conclusion that a school breakfast programme had a beneficial effect on the cognitive and behavioural performance of socially disadvantaged, undernourished children in their first 2 years of school.

    Objective To determine if breakfast consumption or content affects academic achievement measured by standardized tests. Methods Baseline data was collected in fall of 2011 from 698 students (50.5% female, age=7.5±0.6 yrs.) living in the state of Kansas. Academic achievement was assessed using three components from the Wechsler Individual Achievement Test (WIAT-III). Prior to taking the WIAT-III, participants completed a breakfast recall of all the foods and drinks consumed that morning, which was analyzed using NDS-R. WIAT-III scores were compared between breakfast and non-breakfast consumers in a sample (n=162) matched for age, sex, race, education level of both parents, household income, BMI, and cardiovascular fitness, and Pearson correlations were calculated from all breakfast eaters (n=617) between test performance and components of the breakfast. Results When compared to non-breakfast consumers, the breakfast consumers had significantly higher scores in all three WIAT-III components (all pbreakfast consumers, servings of fruit juice were negatively correlated with reading comprehension and fluency standard score and mathematics standard score (both pbreakfast consumption and the content may be associated with improved standardized test performance in elementary school students.

    Skipping breakfast is associated with adverse child health profiles including obesity, higher blood pressure, higher serum cholesterol, and poor cognitive function. We aimed to explore the association between breakfast with school performance and the metabolic syndrome (MetS) in Taiwanese children. Participants were enrolled from the representative Elementary School Children's Nutrition and Health Survey in Taiwan (2001-2002). Diet, waist circumference, blood pressure, blood glucose, triglyceride, and high-density lipoprotein cholesterol concentrations were assessed in 1287 boys and 1114 girls. Their school and social performances were examined using the modified Scale for Assessing Emotional Disturbance questionnaire. Logistic and linear regression analyses were used to estimate the risk of MetS and also the association between breakfast consumption frequency and school or social performance. When breakfast consumption was regular, overall dietary quality was better. Children who consumed breakfast daily exhibited lower risks of high blood pressure (OR=0.37, 95% CI=0.19-0.71) and of MetS (OR=0.22, 95% CI=0.09-0.51) compared with children who consumed breakfast 0-4 times per week. Furthermore, children who consumed breakfast daily exhibited a higher overall competence (OC) score (β=0.71, pschool performance, a lower risk of high blood pressure, and MetS independent of overall dietary quality. Thus, breakfast on school days is a factor in school performance and health. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Recent reports have suggested that a low glycemic index (GI) diet may have a role in the management of obesity through its ability to increase the satiety value of food and modulate appetite. To date, no long-term clinical trials have examined the effect of dietary GI on body weight regulation. The majority of evidence comes from single-day studies, most of which have been conducted in adults. The purpose of this study was to investigate the effect of 3 test breakfasts-low-GI, low-GI with 10% added sucrose, and high-GI-on ad libitum lunch intake, appetite, and satiety and to compare these with baseline values when habitual breakfast was consumed. A 3-way crossover study using block randomization of breakfast type was conducted in a school that already ran a breakfast club. A total of 37 children aged 9 to 12 years (15 boys and 22 girls) completed the study. The proportion of nonoverweight to overweight/obese children was 70:30. Children were divided into 5 groups, and a rolling program was devised whereby, week by week, each group would randomly receive 1 of 3 test breakfasts for 3 consecutive days, with a minimum of 5 weeks between the test breakfasts. Participants acted as their own control. The 3 test breakfasts were devised to match the energy and nutritional content of an individual's habitual breakfast as far as possible. All test breakfasts were composed of fruit juice, cereal, and milk with/without bread and margarine; foods with an appropriate GI value were selected. After each test breakfast, children were instructed not to eat or drink anything until lunchtime, except water and a small serving of fruit supplying approximately 10 g of carbohydrate, which was provided. Breakfast palatability, satiation after breakfast, and satiety before lunch were measured using rating scales based on previously used tools. Lunch was a buffet-style meal, and children were allowed free access to a range of foods. Lunch was served in the school hall where the rest of the

    The composite Sunrise Butte pluton, in the central part of the Blue Mountains Province, northeastern Oregon, preserves a record of subduction-related magmatism, arc-arc collision, crustal thickening, and deep-crustal anatexis. The earliest phase of the pluton (Desolation Creek unit) was generated in a subduction zone environment, as the oceanic lithosphere between the Wallowa and Olds Ferry island arcs was consumed. Zircons from this unit yielded a 206Pb/238U age of 160.2 ± 2.1 Ma. A magmatic lull ensued during arc-arc collision, after which partial melting at the base of the thickened Wallowa arc crust produced siliceous magma that was emplaced into metasedimentary rocks and serpentinite of the overthrust forearc complex. This magma crystallized to form the bulk of the Sunrise Butte composite pluton (the Sunrise Butte unit; 145.8 ± 2.2 Ma). The heat necessary for crustal anatexis was supplied by coeval mantle-derived magma (the Onion Gulch unit; 147.9 ± 1.8 Ma).The lull in magmatic activity between 160 and 148 Ma encompasses the timing of arc-arc collision (159–154 Ma), and it is similar to those lulls observed in adjacent areas of the Blue Mountains Province related to the same shortening event. Previous researchers have proposed a tectonic link between the Blue Mountains Province and the Klamath Mountains and northern Sierra Nevada Provinces farther to the south; however, timing of Late Jurassic deformation in the Blue Mountains Province predates the timing of the so-called Nevadan orogeny in the Klamath Mountains. In both the Blue Mountains Province and Klamath Mountains, the onset of deep-crustal partial melting initiated at ca. 148 Ma, suggesting a possible geodynamic link. One possibility is that the Late Jurassic shortening event recorded in the Blue Mountains Province may be a northerly extension of the Nevadan orogeny. Differences in the timing of these events in the Blue Mountains Province and the Klamath–Sierra Nevada Provinces suggest that

    Although existing evidence links breakfast frequency to better dietary quality, little is known specifically in regard to the benefits associated with eating breakfast together with one's family. The present study describes the prevalence and experience of having family meals at breakfast among rural families and examines associations between meal frequency and adolescent diet quality. Data were drawn from Project BreakFAST, a group-randomized trial aimed at increasing school breakfast participation in rural Minnesota high schools, USA. Linear mixed models were used to examine associations between student reports of family breakfast frequency and Healthy Eating Index 2010 (HEI-2010) scores while accounting for clustering within schools, demographics and household food security. Adolescent students from sixteen schools completed online surveys, height and weight measurements, and dietary recalls at baseline in 2012-2014. The sample included 827 adolescents (55·1 % girls) in grades 9-10 who reported eating breakfast on at most three days per school week. On average, adolescents reported eating breakfast with their family 1·3 (sd 1·9) times in the past week. Family breakfast meals occurred most frequently in the homes of adolescents who reported a race other than white (P=0·002) or Hispanic ethnicity (P=0·02). Family breakfast frequency was directly associated with adolescent involvement in preparing breakfast meals (Pfood patterns at breakfast. Additional research is needed to better inform and evaluate strategies.

    Most studies that assess the effects of breakfast on subsequent mental abilities compared performance in subjects who had or had not consumed this meal. However, characteristics of breakfast itself may induce metabolic and hormonal alterations of the gastrointestinal tract and potentially modify cognitive performance. Moreover, as far as the evidence on the positive effects of having breakfast is becoming more robust, interest may shift to the specific characteristics of an adequate breakfast. The objective was to summarize existing evidence on the role of nutrient composition or energy intake at breakfast on the accomplishment of school-related tasks and cognition. We conducted a systematic review of the literature through the PubMed database. From the literature search, we identified 102 articles, 15 of which met the inclusion criteria. Of these, 3 studies provided information on the relation between cognitive and academic performance and energy intake at breakfast, 11 provided the same information for the macronutrient composition of breakfast, and 1 investigated both the aspects. Eleven studies considered breakfast meals differing in glycemic index/load. Selected studies were generally carried out in well-nourished children and adults of both sexes from general education. They were mostly experimental studies of short duration and had a limited number of subjects. Cognitive and academic performance was investigated by looking at multiple domains, including memory, attention, reasoning, learning, and verbal and math abilities, with a variety of test batteries scheduled at different time points in the morning. Breakfast options differed in terms of included foods and place and time of administration. There is insufficient quantity and consistency among studies to draw firm conclusions. However, whereas the hypothesis of a better and more sustained performance with a breakfast providing >20% daily energy intake still needs substantiation, there does appear to be

    Breakfast has been shown to be beneficial for cognitive and academic performance in school children. However, there is a paucity of studies which examine the relationship between breakfast consumption and academic performance and a complete absence of studies in UK school children. The aim of this study, therefore, was to examine the association between habitual breakfast consumption frequency and Cognitive Abilities Test (CAT) performance, a reasoning test routinely used in UK schools. Adolescents aged 11-13 years (n = 292; males: 53.8%) completed a questionnaire to report usual weekly breakfast intake frequency. Breakfast was subjectively defined by the participants. Habitual weekly breakfast consumption frequency was categorized as rare (0-2 days), occasional (3-4 days), or frequent (5-7 days). Participants' CAT performance was used as a proxy measure of academic performance. The CAT has three components: verbal, non-verbal, and quantitative reasoning. Normative standard age scores (SAS) for verbal, non-verbal, quantitative reasoning, and overall mean SAS were obtained from school records and hierarchical linear regression models were applied, adjusting for the confounders: gender, ethnicity, socio-economic status, English as an Additional Language, and body mass index. Habitual breakfast consumption frequency did not significantly predict any CAT SAS in all models (crude and adjusted). However, methodological considerations which could account for this disagreement with previous research, were identified. These included the isolation of school-day breakfast consumption, use of a standard definition of breakfast, and measurement of actual academic performance. The findings of the current study suggest more comprehensive ways in which future studies might investigate the relationship between habitual breakfast consumption and academic performance.

    The objective of this study was to explore parents', children's, and experts' beliefs and experiences about breakfast motivation, opportunity, and ability and elicit their thoughts on effective interventions to encourage healthy breakfast consumption. The setting was a disadvantaged neighbourhood in Rotterdam, the Netherlands. Focus groups with mothers and children and semi-structured individual interviews with experts were conducted. Interview guides were developed based on the motivation, opportunity, and ability consumer psychology model. Thirty-two mothers of primary school children participated in five group discussions, eight focus groups were conducted with 44 children, and nine experts participated in interviews. Data from expert interviews and group discussions were coded and thematically analysed. The following themes emerged from the focus groups: (1) generally high motivation to have breakfast, (2) improved performance at school is key motivator, (3) limited time hinders breakfast, and (4) lack of nutritional knowledge about high quality breakfast. Experts mentioned lack of effort, knowledge, and time; financial constraints; and environmental issues (food availability) as barriers to breakfasting healthily. Several ways to encourage healthy breakfasting habits were identified: (1) involvement of both children and parents, (2) role models inspiring change, and (3) interactive educational approaches. Experts perceived more problems and challenges in achieving healthy breakfast habits than did mothers and children. Lack of opportunity (according to the children and experts) and ability (according to the experts) were identified, although the motivation to eat a healthy breakfast was present. Predominant barriers are lack of time and nutritional knowledge. Overall, findings suggest educational and social marketing approaches as interventions to encourage healthy breakfast consumption.

    The aim of the current study was to investigate the effect of breakfast consumption on cognitive performance and mood in adolescents, and any interaction that breakfast consumption might have with cognitive load. The rationale for this approach was that the beneficial effects of any intervention with regard to cognitive function may be more readily apparent when more demands are placed on the system. Furthermore, as skipping breakfast is particularly prevalent within this age group, thus, we focused on adolescents who habitually skip breakfast. Cognitive load was modulated by varying the level of difficulty of a series of cognitive tasks tapping memory, attention, and executive functions. Mood measured with Bond-Lader scales (1974) as well as measures of thirst, hunger, and satiety were recorded at each test session both at baseline and after the completion of each test battery. Forty adolescents (mean age = 14:2) participated in this within-subjects design study. According to treatment, all participants were tested before and after the intake of a low Glycaemic index breakfast (i.e., a 35 g portion of AllBran and 125 ml semi-skimmed milk) and before and after no breakfast consumption. Assessment time had two levels: 8.00 am (baseline) and 10.45 am. The orders of cognitive load tasks were counterbalanced. Overall it appeared that following breakfast participants felt more alert, satiated, and content. Following breakfast consumption, there was evidence for improved cognitive performance across the school morning compared to breakfast omission in some tasks (e.g., Hard Word Recall, Serial 3's and Serial 7's). However, whilst participants performance on the hard version of each cognitive task was significantly poorer compared to the corresponding easy version, there was limited evidence to support the hypothesis that the effect of breakfast was greater in the more demanding versions of the tasks.

    The distributions, correlations, and source apportionment of aromatic acids, aromatic ketones, polycyclic aromatic hydrocarbons (PAHs), and trace metals were studied in Canadian high Arctic aerosols. Nineteen PAHs including minor sulfur-containing heterocyclic PAH (dibenzothiophene) and major 6 carcinogenic PAHs were detected with a high proportion of fluoranthene followed by benzo[k]fluoranthene, pyrene, and chrysene. However, in the sunlit period of spring, their concentrations significantly declined likely due to photochemical decomposition. During the polar sunrise from mid-March to mid-April, benzo[a]pyrene to benzo[e]pyrene ratios significantly dropped, and the ratios diminished further from late April to May onward. These results suggest that PAHs transported over the Arctic are subjected to strong photochemical degradation at polar sunrise. Although aromatic ketones decreased in spring, concentrations of some aromatic acids such as benzoic and phthalic acids increased during the course of polar sunrise, suggesting that aromatic hydrocarbons are oxidized to result in aromatic acids. However, PAHs do not act as the major source for low molecular weight (LMW) diacids such as oxalic acid that are largely formed at polar sunrise in the arctic atmosphere because PAHs are 1 to 2 orders of magnitude less abundant than LMW diacids. Correlations of trace metals with organics, their sources, and the possible role of trace transition metals are explained.

    The role of boundary layer mixing is increasingly recognized as an important factor in determining the concentrations of ozone and other trace gases near the surface. While the concentrations at the surface can vary widely due to horizontal transport of chemical plumes, the boundary layer is also characterized by turbulence that follows a diurnal cycle in height and intensity. Surface oxidant concentrations can therefore undergo significant changes even in the absence of photochemistry. A central goal of the Phoenix 2001 Field Campaign was to study vertical mixing with the onset of convection and to quantify the effect of this mixing on chemistry within an urban boundary layer. As part of this study, a series of low altitude aircraft sampling flights were made over the Greater Phoenix area between June 16-30, 2001. The resulting observations, in conjunction with a series of surface measurements and meteorological observations, are being used to study the vertical transport and reactivity of ozone and ozone-precursors shortly after sunrise. Additional details of this campaign are given in Doran, et al. (2002). It was anticipated that turbulence over Phoenix at night would be suppressed as a result of cooling of the boundary layer over the city. By sampling shortly after sunrise, we hoped to collect measurements above the residual nocturnal stable layer and to continue sampling through the developmental period of a convectively active boundary layer. We report here on the first analysis of these observations, made from a Gulstream-1 (G-1) aircraft operated by the U.S. Department of Energy

    We review recently developed new powerful techniques to compute a class of Feynman diagrams at any loop order, known as sunrise-type diagrams. These sunrise-type topologies have many important applications in many different fields of physics and we believe it to be timely to discuss their evaluation from a unified point of view. The method is based on the analysis of the diagrams directly in configuration space which, in the case of the sunrise-type diagrams and diagrams related to them, leads to enormous simplifications as compared to the traditional evaluation of loops in momentum space. We present explicit formulae for their analytical evaluation for arbitrary mass configurations and arbitrary dimensions at any loop order. We discuss several limiting cases in their kinematical regimes which are e.g. relevant for applications in HQET and NRQCD. We completely solve the problem of renormalization using simple formulae for the counterterms within dimensional regularization. An important application is the computation of the multi-particle phase space in D-dimensional space-time which we discuss. We present some examples of their numerical evaluation in the general case of D-dimensional space-time as well as in integer dimensions D = D 0 for different values of dimensions including the most important practical cases D 0 = 2, 3, 4. Substantial simplifications occur for odd integer space-time dimensions where the final results can be expressed in closed form through elementary functions. We discuss the use of recurrence relations naturally emerging in configuration space for the calculation of special series of integrals of the sunrise topology. We finally report on results for the computation of an extension of the basic sunrise topology, namely the spectacle topology and the topology where an irreducible loop is added

    Studies have documented a positive relationship between regular breakfast consumption and cognitive outcomes in youth. However, most of these studies have emphasized specific measures of cognition rather than cognitive performance as a broad construct (e.g., IQ test scores) and have been limited to Western samples of school-age children and adolescents. This study aims to extend the literature on breakfast consumption and cognition by examining these constructs in a sample of Chinese kindergarten-age children. This cross-sectional study consisted of a sample of 1269 children (697 boys and 572 girls) aged 6 years from the Chinese city of Jintan. Cognition was assessed with the Chinese version of the Wechsler preschool and primary scale of intelligence-revised. Breakfast habits were assessed through parental questionnaire. Analyses of variance and linear regression models were used to analyze the association between breakfast habits and IQ. Socioeconomic and parental psychosocial variables related to intelligence were controlled for. Findings showed that children who regularly have breakfast on a near-daily basis had significantly higher full scale, verbal, and performance IQ test scores (all pbreakfast. This relationship persisted for VIQ (verbal IQ) and FIQ (full IQ) even after adjusting for gender, current living location, parental education, parental occupation, and primary child caregiver. Findings may reflect nutritional as well as social benefits of regular breakfast consumption on cognition, and regular breakfast consumption should be encouraged among young children.

    We sought to determine if perceived barriers, benefits, and modifiable behaviors support or interfere with breakfast consumption in a racially and economically diverse rural high school population. The participants were 832 Minnesota adolescents from 16 rural high schools. We used baseline data from a group randomized trial aimed at increasing school breakfast participation through policy and environmental-level school changes. Students completed an online survey asking about demographics, breakfast eating behaviors, and the barriers and benefits of eating as it relates to school performance. Bivariate and multivariate logistic regression, accounting for clustering by school, was performed using SAS. Each scale was modeled independently. Participants were 9th and 10th grade students, 36% free/reduced-price lunch (FRL), 30% non-White, and 55% female. Breakfast skippers compared to nonbreakfast skippers reported fewer school related benefits and beliefs and more barriers to eating breakfast (p breakfast. Future intervention research should focus on alleviating barriers and enhancing education around the school related benefits of eating breakfast. © 2016, American School Health Association.

  14. Breakfast and Snacks: Associations with Cognitive Failures, Minor Injuries, Accidents and Stress

    Full Text Available One strategy for examining effects of nutrients on cognitive function is to initially investigate foods that contain many different nutrients. If effects are demonstrated with these foods then further studies can address the role of specific nutrients. Breakfast foods (e.g., cereals, dairy products and fruit provide many important nutrients and consumption of breakfast has been shown to be associated with beneficial effects on cognitive function. Isolating effects of specific constituents of breakfast has proved more difficult and it is still unclear what impact breakfast has on real-life performance. The present study provided initial information on associations between breakfast consumption and cognitive failures and accidents. A second aim was to examine associations between consumption of snacks which are often perceived as being unhealthy (chocolate, crisps and biscuits. A sample of over 800 nurses took part in the study. The results showed that frequency of breakfast consumption (varied breakfasts: 62% cereal was associated with lower stress, fewer cognitive failures, injuries and accidents at work. In contrast, snacking on crisps, chocolate and biscuits was associated with higher stress, more cognitive failures and more injuries outside of work. Further research requires intervention studies to provide a clearer profile of causality and underlying mechanisms.

    To investigate dietary knowledge and beliefs of schoolchildren, in relationship to breakfast choices, with specific attention to fat and fiber content. Food choice and perceptions were studied by interviews using the "stacking box methodology". Youth (n = 181) aged 11-15 years were instructed to select food items among photographs of breakfast foods. In addition to choosing their own typical breakfasts, they were asked to exchange foods in hypothetical breakfasts to create meals with less fat and more fiber. The interview also dealt with recent changes in breakfast habits, and perceptions of healthy breakfasts, dietary fat, and foods rich in fiber. Data were analyzed by logistic regression. Knowledge concerning sources and health attributes of dietary fiber was associated with usual consumption of bread and breakfast cereals rich in fiber. In a similar way, a positive attitude toward limited fat intake predicted consumption of reduced-fat milk products. However, no association was observed between food choices and knowledge of a food-packaging symbol indicating low-fat and fiber-enriched foods. Lack of awareness of, and knowledge about, healthy eating may be important barriers to the development of health promoting food habits by schoolchildren.

    Full Text Available The principal aims of this study are to describe breakfast consumption patterns of south-eastern Spanish adolescents, examine the relationship between breakfast consumption and feelings of well-being and fitness and compare breakfast behaviour between men and women to identify if there is a gender gap. Design: A cross-sectional research with cluster sampling in two primary schools and seven secondary schools. The instrument used was a modified version of the Kidscreen-27 questionnaire. Sample: 2,125 students aged between 10 and 19 years old from different nationalities, mainly Romanian, Moroccan and Spanish. Results: The study identifies some youngsters who skip breakfast and no have no food intake over the course of the morning. About 35% of the teenagers skip daily breakfast before they leave for school, and a worrying 1,8% do not eat any food during the whole morning. Questionnaire outcomes also expresses that the amount of biscuits ingested increased as the number of times that adolescents have breakfast at home decreases. There are significant gender differences, women it less foods than men. Differences are especially significant in case of milk, bread or cereals and butter or oil. Finally, chisquare contrast analysis show students that have breakfast before leaving to school perceive better feelings about how well and fit they are than those student who do not have breakfast daily. Conclusions. Findings supports the need for further enhance health education programs focused on breakfast habits, especially with women.

    Addressing high-risk dietary patterns among postpartum teens may help reduce weight retention and prevent intergenerational obesity. The objective of this study was to describe the relationship between breakfast consumption and outcomes of snack and beverage intake and body mass index (BMI) among postpartum teens. During 2007-2009, 1,330 postpartum teens across 27 states participated in a cross-sectional, baseline assessment of a group-randomized, nested cohort study. Participants were enrolled in the Parents as Teachers Teen Program and completed a 7-day recall of breakfast, snack, and beverage consumption. BMI was calculated from heights and weights obtained by on-site staff. Sample descriptives were compared across breakfast consumption frequency groupings by one-way analysis of variance tests or χ² tests. General linear models assessed relationships between breakfast consumption and measures of snack and sweetened beverage intake, water consumption, and BMI-for-age percentile. Almost half (42%) of the sample consumed breakfast fewer than 2 days per week. Those who ate breakfast 6 to 7 days/week consumed 1,197 fewer kilocalories per week from sweet and salty snacks, 1,337 fewer kilocalories per week from sweetened drinks, and had a lower BMI compared to those who ate breakfast fewer than 2 days per week (P teens is low, those who regularly consume breakfast had healthier snacking behaviors and weight. Interventions are needed to encourage breakfast consumption among teen mothers. Copyright © 2011 American Dietetic Association. Published by Elsevier Inc. All rights reserved.

  18. More than just a meal: Breakfast club attendance and children’s social relationships

    Full Text Available The health benefits of school food have been widely promoted in recent years while the social opportunities that surround eating occasions at school have received little attention. Breakfast clubs, which take place at the start of the school day, offer a unique opportunity for children to consume a breakfast meal on their school premises in the company of their peers. Alternatively, after school clubs, which take place on school premises at the end of the school day, whilst also providing children with social opportunities tend to focus on sports engagement and skill development. The aim of the current paper is to investigate whether attendance at breakfast clubs and after school clubs has an impact on children’s friendship quality and experiences of peer victimization. Breakfast club attendees, after-school club attendees and non-attendees completed the Friendship Qualities Scale (FQS and the Multidimensional Peer Victimization Scale (MPVS at two time points. Time 1 data were collected two months after the introduction of school clubs. Time 2 data were then collected on the same measures again six months later. Results of the analyses of Time 1 data showed no significant differences between groups on any of the measures at Time 1. However, at Time 2 breakfast club attendees showed improved levels of friendship quality compared to the other two groups. Moreover, analysis of the MPVS data at Time 2 showed that children who attended breakfast club or after school club experienced a decline in victimization across time. The current findings suggest that breakfast club attendance facilitates the quality of children’s relationships with their best friend over time. Additionally, attendance at a breakfast or after school club was associated with a reduction in victimization over time. The results have implications for utilization of breakfast and after school clubs to aid children’s social relationships in school over time.

    The satiating effects of cow dairy have been thoroughly investigated; however, the effects of goat dairy on appetite have not been reported so far. Our study investigates the satiating effect of two breakfasts based on goat or cow dairy and their association with appetite related hormones and metabolic profile. Healthy adults consumed two breakfasts based on goat (G-Breakfast) or cow (C-Breakfast) dairy products. Blood samples were taken and VAS tests were performed at different time points. Blood metabolites were measured and Combined Satiety Index (CSI) and areas under the curves (AUC) were calculated. Desire to eat rating was significantly lower (breakfast & time interaction p cow dairy products, and pointed to a potential association of GLP-1 and triglyceride levels with the mechanisms by which dairy products might affect satiety after the G-Breakfast and C-Breakfast, respectively.

    The primary aim was to examine the daily glycemic response to normal-protein (NP) vs higher-protein (HP) breakfasts in overweight adolescents who habitually skip breakfast (H-BS). The secondary aim examined whether the glycemic response to these meals differed in H-BS vs habitual breakfast consumers (H-BC). Thirty-five girls (age: 19 ± 1 year; body mass index: 28.4 ± 0.7 kg/m(2)) participated in the semi-randomized crossover-design study. The participants were grouped according to habitual breakfast frequency. H-BS (n = 20) continued to skip breakfast (BS) or consumed a NP (12 g protein) or HP (32 g protein) breakfast for 3 days, whereas the H-BC (n = 15) completed the NP and HP breakfast conditions for 3 days. On day 4 of each pattern, an 8 h testing day was completed. The respective breakfast and a standard lunch meal were provided, and plasma was collected to assess morning, afternoon, and total glucose and insulin area under the curves (AUC). In H-BS, the addition of a HP breakfast increased total glucose AUC vs BS (P < 0.05), whereas NP breakfast increased total insulin AUC vs BS (P < 0.05). In H-BC, the HP breakfast reduced morning, afternoon and total glucose AUCs vs NP (all, P < 0.05). No differences in insulin were detected. When comparing the HP-NP differential glycemic responses between groups, H-BS experienced greater afternoon and total glucose AUCs following HP vs NP breakfasts (both, P<0.05). No differences in insulin responses were observed between groups. Novel differences in the glucose response to HP vs NP breakfasts were observed and were influenced by the frequency of habitual breakfast consumption in overweight adolescents.

    2016-01-01

    The study examined the feasibility of utilizing functional magnetic resonance imaging (fMRI) with a group of adolescent boys and girls to assess modifications in cognitive function, dependent upon the nutritional state of the participants. Twenty children aged 12-14 years completed two cognitive trials, in a randomized counterbalanced order, one under fasting condition, one after consuming breakfast, during which continuous fMRI data were acquired. Although no statistically significant (P > 0.05) improvement in task performance was determined, significantly higher activation was recorded in the frontal, premotor, and primary visual cortex areas in the breakfast trial relative to the fasting condition. Such a finding may have important implications in the examination of the role of diet, and specifically breakfast, in determining children's performance within the school environment.

    The purpose of this study was to further explore the association between bullying victimization and breakfast skipping in children and adolescents. Compared to the previous study, we have used a larger and representative sample of middle and high school students, examined the effect of gender, different forms (physical, verbal, theft/vandalism and cyber) and severity of bullying on breakfast eating behaviour. Data from students (2286 boys and 2859 girls) aged 11 to 19 years (mean ± SD age: 14.6 ± 1.9 years) from the 2013 Ontario Student Drug Use and Health Survey (OSDUHS) were analysed using self-reports of being bullied, diet, psychological distress, demographics, socio-economic status, weight status, and substance use. Results revealed greater odds of breakfast skipping in girl victims of physical, verbal, and cyber bullying, and in boy victims of verbal and cyber bullying. There was a dose-response relationship between experience of both school and cyber bullying victimization and breakfast skipping behaviour for both genders. Mediation analysis indicated that psychological distress fully mediated the relationship between both verbal and physical bullying victimization and breakfast skipping in girls, and partially mediated the relationship between verbal bullying victimization and breakfast skipping in boys. Psychological distress also partially mediated the link between cyber bullying victimization and breakfast skipping in both boys and girls. These results corroborate previous findings on the association between bullying victimization and breakfast skipping in children and adolescents. The strong and consistent associations with different forms of bullying victimization, the dose-response relationship, and the mediating role of psychological distress suggest a causal relationship.

    Full Text Available Abstract Background The majority of food expenditures are made in supermarkets and this environment influences our purchasing and food intake. Breakfast cereals are frequently marketed as healthy food choices. The objective of this study was to examine the frequency of in–store promotions for cold breakfast cereals in Canadian supermarkets and to determine whether healthier or less healthy breakfast cereals are promoted more frequently. Methods Data was collected once per week over a four-week period from a convenience sample of the five largest Canadian supermarkets in the Ottawa/Gatineau area. Data collection included the number of shelf facings, promotional displays, and the cost of cereals/100 g. The UK Nutrient Profiling Model was used to determine the healthfulness of each breakfast cereal. Results 29.8% (n = 67 of the 225 unique cereals were classified as healthier and 70.2% (n = 158 were classified as less healthy. Less healthy cereals were displayed at eye level, in the profitable middle shelves, 2.9 times more frequently than healthier cereals. There were 5.3 times more breakfast cereal shelf facings, 4.2 more end cap displays, 1.7 more mid-aisle displays and 3.3 more special pricing signage for less healthy cereals compared to healthier cereals. Less healthy cereals had a significantly higher average total number of shelf facings compared to healthier cereals (t = −4.28 (280.8, p < .001. Conclusions Breakfast cereal manufacturers need to consider reformulation of their breakfast cereals to improve their healthfulness and supermarkets need to increase the marketing of healthy breakfast cereals within their stores.

  12. The Effects of Breakfast Consumption and Composition on Metabolic Wellness with a Focus on Carbohydrate Metabolism.

    2016-05-01

    Findings from epidemiologic studies indicate that there are associations between breakfast consumption and a lower risk of type 2 diabetes mellitus (T2DM) and metabolic syndrome, prompting interest in the influence of breakfast on carbohydrate metabolism and indicators of T2DM risk. The objective of this review was to summarize the available evidence from randomized controlled trials assessing the impact of breakfast on variables related to carbohydrate metabolism and metabolic wellness. Consuming compared with skipping breakfast appeared to improve glucose and insulin responses throughout the day. Breakfast composition may also be important. Dietary patterns high in rapidly available carbohydrate were associated with elevated T2DM risk. Therefore, partial replacement of rapidly available carbohydrate with other dietary components, such as whole grains and cereal fibers, proteins, and unsaturated fatty acids (UFAs), at breakfast may be a useful strategy for producing favorable metabolic outcomes. Consumption of fermentable and viscous dietary fibers at breakfast lowers glycemia and insulinemia. Fermentable fibers likely act through enhancing insulin sensitivity later in the day, and viscous fibers have an acute effect to slow the rate of carbohydrate absorption. Partially substituting protein for rapidly available carbohydrate enhances satiety and diet-induced thermogenesis, and also favorably affects lipoprotein lipids and blood pressure. Partially substituting UFA for carbohydrate has been associated with improved insulin sensitivity, lipoprotein lipids, and blood pressure. Overall, the available evidence suggests that consuming breakfast foods high in whole grains and cereal fiber, while limiting rapidly available carbohydrate, is a promising strategy for metabolic health promotion. © 2016 American Society for Nutrition.

    2014-08-01

    Breakfast skipping is a health concern that has well-known negative consequences physically and psychologically. It is therefore important to understand why children skip breakfast. The purpose of this study was to establish whether the experience of bullying and cyberbullying impacts upon breakfast skipping and to further evaluate whether the inability for youths to cope with bullying victimization affects their mental health (depression), and in turn predicts breakfast skipping. Data were obtained from the Eastern Ontario 2011 Youth Risk Behaviour Survey, a cross-sectional regional school-based survey of middle and high school students (11-20 years old) across the five counties of Eastern Ontario, Canada (N = 3035). Self-reported data about children's experiences of bullying victimization, breakfast eating habits, socio-economical status, depression, and other risk behaviours were analysed. Approximately half of the participants (50.4%) reported not eating breakfast on a regular basis: 26.3% and 24.1% reported often (usually eat breakfast three times or more per week) and frequent (usually eat breakfast twice a week or less) breakfast skipping behaviour, respectively. Victims of both cyberbullying and school bullying presented greater likelihood of often (adjusted relative risk ratio (RR) = 1.55; 95% confidence interval (CI) = 1.17-2.06) and frequent (RR = 1.97; 95% CI = 1.28-3.03) breakfast skipping. Mediation analysis further showed that depression fully mediated the relationship between school bullying victimization and frequent breakfast skipping. Moreover, depression partially mediated the associations between both cyberbullying and school bullying with frequent breakfast skipping. These findings highlight the potential interrelationships between cyberbullying, school bullying and depression in predicting unhealthy breakfast skipping behaviour in children.

    2010-09-01

    The aim of this study was to assess how the glycaemic potency (blood glucose (BG)-raising potential) of breakfast is associated with cognitive function (CF) in school children, taking into account important confounders, including iron status, underlying physiological adaptations and socio-economic status. Sixty children aged 11-14 years were selected on the basis of having breakfast habitually. Their breakfast and any snacks eaten on the morning of the study were recorded. They were categorized into four groups according to the glycaemic index (GI) and glycaemic load (GL) of the breakfast: low-GI, high-GL; high-GI, high-GL; low-GI, low-GL and high-GI, low-GL above or below the median for GI=61 and GL=27.

    Breakfast omission may reduce daily energy intake. Exercising fasted impairs performance compared with exercising after breakfast, but the effect breakfast omission has on evening exercise performance is unknown. This study assessed the effect of omitting breakfast on evening exercise performance and within-day energy intake. Ten male, habitual breakfast eaters completed two trials in a randomized, counterbalanced order. Subjects arrived at the laboratory in an overnight-fasted state and either consumed or omitted a 733 ± 46 kcal (3095 ± 195 kJ) breakfast. Ad libitum energy intake was assessed at 4.5 h (lunch) and 11 h (dinner). At 9 h, subjects completed a 30-min cycling exercise at approximately 60% VO2peak, followed by a 30-min maximal cycling performance test. Food was not permitted for subjects once they left the laboratory after dinner until 0800 h the following morning. Acylated ghrelin, GLP-1(7-36), glucose, and insulin were assessed at 0, 4.5, and 9 h. Subjective appetite sensations were recorded throughout. Energy intake was 199 ± 151 kcal greater at lunch (P daily energy intake but may impair performance later that day, even after consuming lunch.

    Preschool Mexican children consume 7% of their total energy intake from processed breakfast cereals. This study characterized the nutritional quality and labelling (claims and Guideline Daily Amount (GDA)) of the packaged breakfast cereals available in the Mexican market. Photographs of all breakfast cereals available in the 9 main food retail chains in the country were taken. The nutrition quality of cereals was assessed using the United Kingdom Nutrient Profiling Model (UKNPM). Claims were classified using the International Network for Food and Obesity/non-communicable Diseases Research, Monitoring and Action Support (INFORMAS) taxonomy and the GDA was defined according to the Mexican regulation, NOM-051. Overall, a total of 371 different breakfast cereals were analysed. The nutritional profile showed that 68.7% were classified as "less healthy". GDAs and claims were displayed more frequently on the "less healthy" cereals. Breakfast cereals within the "less healthy" category had significantly higher content of energy, sugar and sodium ( p < 0.001). Most of the claims were displayed in the "less healthy" cereals ( n = 313). This study has shown that there is a lack of consistency between the labelling on the front of the pack and the nutritional quality of breakfast cereals.

  18. Psychosocial, behavioural, pedagogical, and nutritional proposals about how to encourage eating a healthy breakfast

    2014-01-01

    Background Even if more and more evidences have highlighted the importance of breakfast in the growth and development of children, from 10 to 30% of US and European children and adolescents regularly skip breakfast. Thus, there is still a lot to be done before breakfast becomes a daily habit. The aim of this paper is to try and understand how it is possible to overcome the real or imaginary difficulties associated with skipping breakfast by psychosocial, behavioural, pedagogical and nutritional proposals. Discussion Schools are the best context where perform healthy interventions because it is here that children learn about the importance of good health at an age when the school still plays a major role in their education. Some school interventions, based on solid theories as the Self Determination Theory and the Behaviour Analysis, have been implemented in the last years to promote health behaviour such as intake of fruit and vegetables and physical activities. Cognitive behaviour therapy is the most closely monitored type of treatment/cure for obesity in randomised controlled trials. Moreover some associations such as the National Association of Food Science Specialists have drawn an own method to encourage food education at school and promote the importance of prevention. These projects could be used as starting point to perform interventions focus on breakfast. Summary Increase the consumption of breakfast between children is very important. Efforts should be done to drawn new school projects based on scientific-evidences. PMID:25125024

    During the recovery phase of the 22-23 June 2015 superstorm multiple DMSP spacecraft observed two separate and short-lived (~ 30 minutes) events of localized cooling in the topside equatorial ionosphere (~840 km) in the post-sunrise region (between 6:15 and 7:30 local time). The ion temperatures dropped from the nominal 2000-3000° observed in these regions to 1000 to 1500°. This cooling effect was not observed on the corresponding duskside equatorial crossings of the DMSP spacecraft during this storm. Further, these cooling events do not normally occur during major storms; no such phenomenon was observed by DMSP during the March 2015 superstorm. Flow data from DMSP and the CINDI instruments on the C/NOFS spacecraft indicate these cooling events are associated with short-lived vertical flows bringing up cooler plasma from lower altitudes. The two cooling events correspond to large northward turnings of the IMF during the storm and these are being explored as a possible trigger mechanism.

    Quantitative scenarios from energy-economic models inform decision-making about uncertain futures. Now, research shows the different ways these scenarios are subsequently used by users not involved in their initial development. In the absence of clear guidance from modellers, users may place too much or too little confidence in scenario assumptions and results.

    The evolution of the physical parameters of magnetic bright points (MBPs) located in the quiet Sun (mainly in the interwork) during their lifetime is studied. First, we concentrate on the detailed description of the magnetic field evolution of three MBPs. This reveals that individual features follow different, generally complex, and rather dynamic scenarios of evolution. Next, we apply statistical methods on roughly 200 observed MBP evolutionary tracks. MBPs are found to be formed by the strengthening of an equipartition field patch, which initially exhibits a moderate downflow. During the evolution, strong downdrafts with an average velocity of 2.4 km s{sup –1} set in. These flows, taken together with the concurrent strengthening of the field, suggest that we are witnessing the occurrence of convective collapses in these features, although only 30% of them reach kG field strengths. This fraction might turn out to be larger when the new 4 m class solar telescopes are operational as observations of MBPs with current state of the art instrumentation could still be suffering from resolution limitations. Finally, when the bright point disappears (although the magnetic field often continues to exist) the magnetic field strength has dropped to the equipartition level and is generally somewhat weaker than at the beginning of the MBP's evolution. Also, only relatively weak downflows are found on average at this stage of the evolution. Only 16% of the features display upflows at the time that the field weakens, or the MBP disappears. This speaks either for a very fast evolving dynamic process at the end of the lifetime, which could not be temporally resolved, or against strong upflows as the cause of the weakening of the field of these magnetic elements, as has been proposed based on simulation results. It is noteworthy that in about 10% of the cases, we observe in the vicinity of the downflows small-scale strong (exceeding 2 km s{sup –1}) intergranular upflows

    Skipping breakfast has been considered a representative unhealthy behavior, but there is little information about the combined effects of breakfast skipping and other unhealthy health habits, especially smoking. First this cross-sectional study investigated unhealthy behaviors among breakfast skippers, and then examined the impact of the combined association of skipping breakfast and smoking on health. A total of 1,200 adults living in one Japanese community were sent questionnaires to elicit data on age, gender, breakfast-eating frequency, and other lifestyle habits. A total 603 of people returned their questionnaires (response rate: 50.3%), and 493 (230 men and 263 women) questionnaires were considered appropriate for analysis. Smoking rate in men (mean age, 53.7 years) and women (mean age, 50.4 years) was 41.3%, and 9.5%, respectively. Skipping breakfast was more prevalent in people under age 50 years (p related to other unhealthy behaviors. Binary logistic regression identified current smoking as the most significant factor related to breakfast skipping (3.10, 95%CI 1.50-6.39). Other factors included, age younger than 50 years (3.04, 95%CI 1.31-7.06) and poor sleeping quality (2.06, 95%CI 1.00-4.25). After examining the combined impact of skipping breakfast and smoking, the highest odds ratio for a diagnosis of diabetes mellitus was found among those who smoked and skipped breakfast (4.68, 95% CI: 1.46-15.05). Moreover, skipping breakfast among non-smokers showed a high association with perceived stress (2.83, 95% CI: 1.05-7.61). In conclusion, the combined unhealthy behaviors of skipping breakfast and smoking are associated with the prevalence of diabetes mellitus.

    This study investigated the associations of breakfast skipping with obesity and health-related quality of life (QOL). We also tested the hypothesis that there is a dose-dependent relationship between frequency of breakfast consumption and prevalence of obesity. This cross-section study used a national representative sample (n=15 340) from the 2005 Taiwan National Health Interview Survey. Breakfast skippers were defined as those who ate breakfast about once a week or less often and those who never ate breakfast. Individuals were classified as 'obese' if their body mass index was >or=27. Health-related QOL was assessed using the Medical Outcome Studies 36-Item Short-Form (SF-36) Health Survey. Logistic regression was used to examine the odds ratio of obesity and associated 95% confidence intervals (CIs) in breakfast skippers compared with breakfast eaters. Multivariable logistic regression modeling was used to adjust all risk estimates for covariates. The unadjusted odds ratio of obesity in breakfast skippers was 1.23 (95% CI: 1.06, 1.43). The odds of developing obesity for breakfast skippers was 1.34 (95% CI: 1.15, 1.56) controlling for age, sex, marital status, educational level, monthly income, smoking, alcohol, betel nut chewing and exercise habit. The Cochran-Armitage trend test revealed that the prevalence rate of obesity decreased as the frequency of breakfast consumption increased (P=0.005). Breakfast skippers had significantly worse health-related QOL than breakfast eaters (Pbreakfast skippers had significantly lower scores in 5 out of 8 domain scores of the SF-36, namely general health perceptions (Pmental health (Pbreakfast eating in obesity prevention.

    As an introduction to this special issue 'Worlds of difference: Scenarios's for the economy, energy and the environment 1990-2015', an outline is given of the future of the world and the Netherlands, based on four scenarios. These scenarios are published in 'Scanning the future' in May 1992 by the CPB, the Dutch Central Planning Bureau. The Global Shift (GS) scenario is characterized by a very dynamic technological development, the free market perspective, strong economic growth in the Asian economies, and a relative economic regression in Western Europe. In the European Renaissance (ER) scenario the technological development is less dynamic and more gradual than in the GS scenario. The Balanced Growth (BG) scenario is dominated by a sustainable economic development and a strong technological dynamic development. The Global Crisis (GC) scenario shows a downward spiral in many areas, stagnating developments and fragile economies as results of the trends in the eighties. The first three scenarios are elaborated for the Netherlands. Also attention is paid to the aims and meaning of long-term scenarios. 2 figs., 2 tabs., 3 refs

    There have been no comprehensive reviews of the relation of breakfast cereal consumption to nutrition and health. This systematic review of all articles on breakfast cereals to October 2013 in the Scopus and Medline databases identified 232 articles with outcomes related to nutrient intake, weight, diabetes, cardiovascular disease, hypertension, digestive health, dental and mental health, and cognition. Sufficient evidence was available to develop 21 summary evidence statements, ranked from A (can be trusted to guide practice) to D (weak and must be applied with caution). Breakfast cereal consumption is associated with diets higher in vitamins and minerals and lower in fat (grade B) but is not associated with increased intakes of total energy or sodium (grade C) or risk of dental caries (grade B). Most studies on the nutritional impact are cross-sectional, with very few intervention studies, so breakfast cereal consumption may be a marker of an overall healthy lifestyle. Oat-, barley-, or psyllium-based cereals can help lower cholesterol concentrations (grade A), and high-fiber, wheat-based cereals can improve bowel function (grade A). Regular breakfast cereal consumption is associated with a lower body mass index and less risk of being overweight or obese (grade B). Presweetened breakfast cereals do not increase the risk of overweight and obesity in children (grade C). Whole-grain or high-fiber breakfast cereals are associated with a lower risk of diabetes (grade B) and cardiovascular disease (grade C). There is emerging evidence of associations with feelings of greater well-being and a lower risk of hypertension (grade D), but more research is required. PMID:25225349

    To carry out a descriptive study on the breakfast model in a college population and to analyze the energy and nutrients provided, in connection with established nutritional requirements. Registry of food intake for breakfast (on rising and mid-morning snack) of a school day in a sample of 740 college students (286 men and 454 women) with ages ranging 19-24 years. Gender, age, weight, height, and body mass index, and type of residence were collected from each interviewee. Percentages intakes of nutrients have been calculated in proportion to established dietary recommendations (%IR). 93.2% had breakfast on rising and 83.8% took a mid-morning snack daily, and 53.5% do both intakes. The most common foods were dairy products (92.6%), cereals (58.8%) and sweet food (57.9%) at breakfast, and cereals (46.6%), fruits (40.7%) and sausages (34.9%) at mid-morning. The %IR of the calorie intake was 24.4% in males and 24.6% in females (n.s.). The %IR of the cholesterol intake was 38.2% in males and 23.9% in females (p breakfast. This breakfast model differs from the prototype of a healthy diet through an excessive consumption of sweet foods (early breakfast) and meat and derivatives (snack). Half of interviewee did not a mid-morning snack and the morning caloric intake was below recommended.

In a randomized crossover design, 12 healthy individuals (6M/6F; BMI 22.2 ± 0.4 kg/m2; 27 ± 1.3 years, mean ± SEM underwent 50 g OGTT (A and 3 breakfasts (B1: milk and cereals; B2: milk, apple, and chocolate cream-filled sponge cake; B3: milk, apple, bread, and hazelnut chocolate cream to assess plasma glucose-, insulin-, and ghrelin excursions. An electroencephalography was performed before and 100 min after consumption of each load to measure the latency of frontal P300 evoked potentials as index of cognitive performance. Breakfasts B1 and B2 exhibited significantly lower glycemic and insulinemic responses as compared to A. Breakfast B3 exhibited significantly lower glycemic, but not insulinemic response, as compared to A. Final plasma ghrelin inhibition was more pronounced, albeit not significantly, in all breakfasts with respect to A. P300 latency tended to decrease following each of the three breakfasts, but B3 was the only breakfast capable to elicit a statistically significant reduction in P300 latency with respect to A (p<0.01, suggesting ameliorated cognitive performance. Such amelioration was correlated with the 2-hour final inhibition of plasma ghrelin concentration (r=0.61, p=0.01.

    The supplementation of a breakfast by 10 g of guar, pectin, agar or locust bean gum in powder form in 13 maturity onset, non-insulin dependent diabetics failed to decrease significantly the post-prandial rise in plasma glucose and insulin seen after a similar meal without the supplement. The values of one hour post-prandial increment in blood glucose seen with guar powder were, for control meal (mean +/- SEM) 5.8 %/- 0.4 mmol/l, for test, 5.7 +/- 0.5; with pectin powder, control 6.4 +/- 0.8 mmol/l, test 5.0 +/- 1.2 mmol/l; with agar powder, control 7.5 +/- 1.0, test 7.0 +/- 0.5; with locust bean gum powder, control 5.9 +/- 1.0, test 5.0 +/- 0.7. The equivalent values for one hour insulin (microU/ml, mean +/- SEM) were, for guar powder, 51 +/0 21 and 51 +/- 16; for pectin powder 60 +/- 24 and 63 +/- 17; for agar powder, 27 +/- 9 and 36 +/- 11 and, for locust bean gum powder 53 +/- 26 and 62 +/- 18. The guar, pectin and locust gum tended to form lumps, and all the substances tested were unpalatable in powder form producing feelings of abdominal discomfort and abnormal fullness. Administering the same quantity of guar or pectin in a well hydrated form (but not premixed with the carbohydrate portion of the food) to the same people under identical conditions did not enhance its effectiveness. Supplementing diets with any of these sources of dietary fibre in either of these forms and in these amounts is unlikely to be beneficial in the management of non-insulin dependent diabetes.

    Few studies examined the association between time-of-day of nutrient intake and the metabolic syndrome. Our goal was to compare a weight loss diet with high caloric intake during breakfast to an isocaloric diet with high caloric intake at dinner. Overweight and obese women (BMI 32.4 ± 1.8 kg/m(2) ) with metabolic syndrome were randomized into two isocaloric (~1400 kcal) weight loss groups, a breakfast (BF) (700 kcal breakfast, 500 kcal lunch, 200 kcal dinner) or a dinner (D) group (200 kcal breakfast, 500 kcal lunch, 700 kcal dinner) for 12 weeks. The BF group showed greater weight loss and waist circumference reduction. Although fasting glucose, insulin, and ghrelin were reduced in both groups, fasting glucose, insulin, and HOMA-IR decreased significantly to a greater extent in the BF group. Mean triglyceride levels decreased by 33.6% in the BF group, but increased by 14.6% in the D group. Oral glucose tolerance test led to a greater decrease of glucose and insulin in the BF group. In response to meal challenges, the overall daily glucose, insulin, ghrelin, and mean hunger scores were significantly lower, whereas mean satiety scores were significantly higher in the BF group. High-calorie breakfast with reduced intake at dinner is beneficial and might be a useful alternative for the management of obesity and metabolic syndrome. Copyright © 2013 The Obesity Society.

The aim of our study was to investigate the relationship between the variation of hormonal and metabolic postprandial parameters induced by breakfast consumption or fasting and cognitive performance in obese children. Cross-sectional study for repeated measures. Memory and attention assessment tests, hormones and nutrient oxidation were measured before and after consuming breakfast vs fasting in 10 prepubertal obese children. Fasting induced a significant (PContinuous Performance Test II (a global index of inattention) and the Test of Memory and Learning Word Selective Reminding (a test of verbal memory), whereas no changes were found after breakfast. Fasting was associated with a reduction of insulin and an increase in glucagon, with no changes in glucose. The increase in inattention was associated with a reduction of carbohydrate oxidation (ρ=-0.66, Pbreakfast or fasting, whereas Ghrelin was significantly lower. No association between postprandial hormone variation and cognitive performance was found. Attention and visual memory performance in the morning were reduced when the children skipped breakfast. No association was found with hormones or metabolic changes, but we did find an association with a reduction of carbohydrate oxidation. Nevertheless, these preliminary findings need confirmation in larger sample size.

    Breakfast is the most important daily meal, but neglected more than other meals by children and adolescents. The aim of this study was to evaluate the effectiveness of an educational intervention, based on the Theory of Reasoned Action (TRA) to increase breakfast consumption among school children in Bandar Abbas, Iran. In this quasi experimental study which was conducted in 2012, 88 students of four secondary schools in Bandar Abbas, south of Iran, were enrolled. Multi-stage cluster sampling was performed with random allocation of interventional and control groups. The study tool was a questionnaire which was filled by the students before and two months after the educational intervention. For data analysis, statistical tests including paired-samples t-test, independent samples t-test, Wilcoxon test, and Mann-Whitney test were used through SPSS v.18 software. The result of the study showed that application of TRA significantly increased scores of behavior of breakfast consumption (p<0.01). After the intervention, a significant increase was revealed in all nutrition intakes, except for fat and sugar (p<0.01). The findings support application of the TRA in improving the intention and behavior of breakfast consumption. Applying this theory for designing interventions to increase breakfast eating is recommended.

In this cross-sectional web-based study, all students of Qazvin University of Medical Sciences in Iran who attended course classes were invited to participate in the study. Five hundred forty-one students filled out the web-based questionnaire which included questions related to measurement of happiness, breakfast, fruit and vegetable consumption and socio-economic and demographic information. Analysis of covariance was used to assess the relationship between happiness and breakfast, fruit and vegetable consumption by adjustments for covariates. Measure of happiness was positively associated with eating breakfast, number of meals eaten daily and the amount of fruit and vegetable consumption (P values were breakfast every day, more than 8 servings of fruit and vegetables daily, and had 3 meals in addition to 1-2 snacks per day had the highest happiness score. Healthier behavior pattern was associated with higher happiness scores among medical students.

    To examine the relationship between mental distress, academic performance and regular breakfast consumption across gender and immigration status. Cross-sectional population-based study. Two four-page questionnaires were filled in during two school sessions. All junior high schools in Oslo, Norway using the classroom as the setting for the study. All 10th grade students 15-16 years olds in 2000 and 2001. Of 8316 eligible students, 7343 (88.3%) participated in the study. All immigrant groups, except the Western countries group, are skipping breakfast more often than Norwegian students, and girls more often than boys (27 versus 19%). After adjustment for possible confounding factors, the odds ratio (OR) for being mentally distressed when eating breakfast seldom/never compared with every day was 3.0 (2.0-4.5) for boys, 1.6 (1.2-2.1) for girls and 1.6 (1.5-2.6) for the immigrant group. The comparable OR for having low school grades was similar for boys and girls, 2.0 (1.3-3.0), and 1.6 (1.5-2.6) for the immigrant groups. Skipping breakfast is a common feature among 10th grade students. The implications of skipping breakfast on mental distress and academic performance are stronger for boys than girls and stronger for Norwegians compared with immigrants.

    Food intake and exercise have been shown to alter body satisfaction in a state-dependent manner. One-time consumption of food perceived as unhealthy can be detrimental to body satisfaction, whereas an acute bout of moderate-intensity aerobic exercise can be beneficial. The current study examined the effect of exercise on state body image and appearance-related self-esteem following consumption of isocaloric foods perceived as healthy or unhealthy in 36 female college students (18-30 years old) in the Northeastern United States. Using a randomized-controlled design, participants attended six study sessions with breakfast conditions (healthy, unhealthy, no food) and activity (exercise, quiet rest) as within-participants factors. Body image questionnaires were completed prior to breakfast condition, between breakfast and activity conditions, and following activity condition. Results showed that consumption of an unhealthy breakfast decreased appearance self-esteem and increased body size perception, whereas consumption of a healthy breakfast did not influence appearance self-esteem but increased body size perception. Exercise did not influence state body image attitudes or perceptions following meal consumption. Study findings suggest that morning meal type, but not aerobic exercise, influence body satisfaction in college-aged females. Copyright © 2018. Published by Elsevier Ltd.

    This study aimed to observe the influence of the monotonous consumption of two types of fibre-enriched bread at breakfast on hedonic liking for the bread, subsequent hunger and energy intake. Two groups of unrestrained normal weight participants were given either white sandwich bread (WS) or multigrain sandwich bread (MG) at breakfast (the sensory properties of the WS were more similar to the usual bread eaten by the participants than those of the MG). In each group, two 15-day cross-over conditions were set up. During the experimental condition the usual breakfast of each participant was replaced by an isocaloric portion of plain bread (WS or MG). During the control condition, participants consumed only 10 g of the corresponding bread and completed their breakfast with other foods they wanted. The results showed that bread appreciation did not change over exposure even in the experimental condition. Hunger was lower in the experimental condition than in the control condition. The consumption of WS decreased energy intake while the consumption of MG did not in the experimental condition compared to the corresponding control one. In conclusion, a monotonous breakfast composed solely of a fibre-enriched bread may decrease subsequent hunger and, when similar to a familiar bread, food intake. Copyright © 2011.

    To measure fluid milk waste in a US School Breakfast in the Classroom Program and estimate its nutritional, economic, and environmental effects. Fluid milk waste was directly measured on 60 elementary school classroom days in a medium-sized, urban district. The US Department of Agriculture nutrition database, district cost data, and carbon dioxide equivalent (CO 2 e) emissions and water footprint estimates for fluid milk were used to calculate the associated nutritional, economic, and environmental costs. Of the total milk offered to School Breakfast Program participants, 45% was wasted. A considerably smaller portion of served milk was wasted (26%). The amount of milk wasted translated into 27% of vitamin D and 41% of calcium required of School Breakfast Program meals. The economic and environmental costs amounted to an estimated $274 782 (16% of the district's total annual School Breakfast Program food expenditures), 644 893 kilograms of CO 2 e, and 192 260 155 liters of water over the school year in the district. These substantial effects of milk waste undermine the School Breakfast Program's capacity to ensure short- and long-term food security and federal food waste reduction targets. Interventions that reduce waste are urgently needed.

    Full Text Available Background: The elimination of breakfast and the high consumption of low-value snacks are becoming more frequent and common among adolescents. Nutrition is a complex behavioral phenomenon that is associated with the specific cultural and environmental issues of each society as well as psychological features.This qualitative research was conducted to identify factors affecting breakfast consumption behavior in adolescents using the social marketing framework. Materials and Methods: A qualitative research based on the social marketing framework was conducted through directed content analysis in the high schools of Isfahan and Khorramabad, Iran, in 2016. Data were collected through seven focus group discussions and 33 in-depth, semi-structured; interviews conducted in person with both male and female students, the parents, and the teachers and were analyzed simultaneously in three phases, namely preparation, organization and reporting. Results: The results obtained in the present study within the social marketing framework were coded into the four categories of product, place, price and promotion. The product category had four subcategories, including favorite taste sought in breakfast, breakfast preparation, breakfast serving style, variety and the healthful features of breakfast. The price category had four subcategories, including time, psychological, social and financial prices. The promotion category had three subcategories, including official channels, unofficial channels, and educational materials and equipment. The place category had two subcategories, including having breakfast at school or having breakfast in an outdoor space. Conclusion: The promotion of healthy breakfast as a product, requires that first its important features be considered, including the favorite taste sought in breakfast, second that it be promoted through channels most popular with students, and most importantly, that its price be reduced by using incentives such as

    Full Text Available Scenarios are employed to address a large number of future environmental and socioeconomic challenges. We present a conceptual framework for the development of scenarios to integrate the objectives of different stakeholder groups. Based on the framework, land-use scenarios were developed to provide a common base for further research. At the same time, these scenarios assisted regional stakeholders to bring forward their concerns and arrive at a shared understanding of challenges between scientific and regional stakeholders, which allowed them to eventually support regional decision making. The focus on the integration of views and knowledge domains of different stakeholder groups, such as scientists and practitioners, required rigorous and repeated measures of quality control. The application of the integrative concept provided products for both stakeholder groups, and the process of scenario development facilitated cooperation and learning within both the scientist and practitioner groups as well as between the two groups.

    Full Text Available Childhood diet is important for brain development. Furthermore, the quality of breakfast is thought to affect the cognitive functioning of well-nourished children. To analyze the relationship among breakfast staple type, gray matter volume, and intelligence quotient (IQ in 290 healthy children, we used magnetic resonance images and applied voxel-based morphometry. We divided subjects into rice, bread, and both groups according to their breakfast staple. We showed that the rice group had a significantly larger gray matter ratio (gray matter volume percentage divided by intracranial volume and significantly larger regional gray matter volumes of several regions, including the left superior temporal gyrus. The bread group had significantly larger regional gray and white matter volumes of several regions, including the right frontoparietal region. The perceptual organization index (POI; IQ subcomponent of the rice group was significantly higher than that of the bread group. All analyses were adjusted for age, gender, intracranial volume, socioeconomic status, average weekly frequency of having breakfast, and number of side dishes eaten for breakfast. Although several factors may have affected the results, one possible mechanism underlying the difference between the bread and the rice groups may be the difference in the glycemic index (GI of these two substances; foods with a low GI are associated with less blood-glucose fluctuation than are those with a high GI. Our study suggests that breakfast staple type affects brain gray and white matter volumes and cognitive function in healthy children; therefore, a diet of optimal nutrition is important for brain maturation during childhood and adolescence.

    Full Text Available Abstract Background Immigrant children face an increased risk of being overweight. Little is known about how immigrant families perceive school programs that may help prevent obesity, such as walking to school and school breakfast. Methods Six focus groups (n = 53 were conducted with immigrant parents of school-aged children, two each in three languages: Vietnamese, Spanish, and Somali. A facilitator and translator conducted the focus groups using a script and question guide. Written notes and audio transcripts were recorded in each group. Transcripts were coded for themes by two researchers and findings classified according to an ecological model. Results Participants in each ethnic group held positive beliefs about the benefits of walking and eating breakfast. Barriers to walking to school included fear of children's safety due to stranger abductions, distrust of neighbors, and traffic, and feasibility barriers due to distance to schools, parent work constraints, and large families with multiple children. Barriers to school breakfast participation included concerns children would not eat due to lack of appealing/appropriate foods and missing breakfast due to late bus arrival or lack of reminders. Although some parents acknowledged concerns about child and adult obesity overall, obesity concerns did not seem personally relevant. Conclusion Immigrant parents supported the ideals of walking to school and eating breakfast, but identified barriers to participation in school programs across domains of the ecological model, including community, institution, and built environment factors. Schools and communities serving immigrant families may need to address these barriers in order to engage parents and children in walking and breakfast programs.

    The majority of food expenditures are made in supermarkets and this environment influences our purchasing and food intake. Breakfast cereals are frequently marketed as healthy food choices. The objective of this study was to examine the frequency of in-store promotions for cold breakfast cereals in Canadian supermarkets and to determine whether healthier or less healthy breakfast cereals are promoted more frequently. Data was collected once per week over a four-week period from a convenience sample of the five largest Canadian supermarkets in the Ottawa/Gatineau area. Data collection included the number of shelf facings, promotional displays, and the cost of cereals/100 g. The UK Nutrient Profiling Model was used to determine the healthfulness of each breakfast cereal. 29.8% (n = 67) of the 225 unique cereals were classified as healthier and 70.2% (n = 158) were classified as less healthy. Less healthy cereals were displayed at eye level, in the profitable middle shelves, 2.9 times more frequently than healthier cereals. There were 5.3 times more breakfast cereal shelf facings, 4.2 more end cap displays, 1.7 more mid-aisle displays and 3.3 more special pricing signage for less healthy cereals compared to healthier cereals. Less healthy cereals had a significantly higher average total number of shelf facings compared to healthier cereals (t = -4.28 (280.8), p supermarkets need to increase the marketing of healthy breakfast cereals within their stores.

    The effect of eating speed at a meal on appetite gut hormone responses and future food consumption is not clear. This study examined the effect of eating speed at breakfast on postprandial gut hormone responses, subjective appetite, and daily food consumption. Twenty-five participants [68% men; age, 25.9 (8.1) years; body mass index, 25.0 (3.2) kg/m] were recruited. Each participant consumed the same breakfast at a slow (30 minutes) and fast (10 minutes) speed, on 2 separate days, in a randomized crossover design. Blood samples were collected in the fasting state and 3 hours postprandially during each eating condition. Appetite was assessed over the same period using visual analog scales. Blood concentrations of orexigenic hormone, ghrelin, and anorexigenic hormones, glucagon-like peptide-1 (GLP-1) and peptide YY (PYY), were determined. Daily food intake was measured, by food recall, after the slow and fast breakfast. Mixed-model repeated-measures analysis showed no eating condition or eating condition by time interaction effect on ghrelin, GLP-1, PYY, hunger, or fullness. Significant eating speed by time interaction effect on desire to eat was found (P=0.007). Desire to eat was lower at 60 minutes (P=0.007) after breakfast began during the slow versus fast eating condition. Eating speed at breakfast did not affect daily energy and macronutrient intake. Eating speed at breakfast did not affect postprandial ghrelin, GLP-1, PYY, hunger, and fullness values or daily energy and macronutrient intake. Desire to eat was lower at 60 minutes in the slow versus fast eating condition, but this result could not be explained by the changes in meal-related hormones measured in the study.

    Despite the importance of breakfast, especially for students, unfortunately, this meal is usually ignored in daily routine. The aim of this study was to identify determinants among female high school students of Yazd province based on the Pender Health Promotion Model. This was a cross-sectional study conducted to examine 200 female high school students of Yazd, selected by cluster sampling method in 2016. A researcher-made questionnaire, based on Pender's Health Promotion Model, was used as a data collection tool. A panel of experts and Cronbach's alpha coefficient were used to confirm the questionnaire validity and reliability. In order to analyze descriptive data, SPSS version 22 was used. AMOS software (v.23) was employed for path analysis. Direct impact of activity -related affect (0.300), interpersonal influences (0.276), and perceived barriers to eating breakfast (-0.223) were approved at significance level p<0.000. By influencing perceived barriers, perceived self-efficacy and previous related behavior indirectly affected breakfast consumption. These components determined 33% of breakfast consumption. By planning to create a positive feeling in students to have breakfast, to involve family and friends to encourage students to eat breakfast, to reduce barriers to have breakfast by increasing students' self-efficacy, the behavior of having breakfast among students can be improved.

Blood samples were collected at 60 and 120 min after each breakfast to determine glucose and insulin levels. Vascular parameters were measured at 15 min intervals. Augmentation index (AIx was studied as a primary outcome. Secondary outcomes comprised glucose, insulin, heart rate (HR and pulse pressures (PPs. We found a trend toward increased AIx, HR and PPs for the HGI versus the LGI breakfast. A significant interaction between the type of breakfast consumed and all measured parameters was identified (p < 0.05 except for central PP. Stratifying data by sex, this interaction remained significant for AIx and augmentation pressure only in males (p < 0.05. In conclusion, breakfast GI could affect postprandial vascular responses in young healthy adults.

    To study the relationship between the breakfast quality and skipping it on academic performance of a population of adolescents. A nutritional study on the breakfast quality has been performed in a population of adolescents from Guadalajara (467 young people; age: 12-17 years) by means of questionnaires of seven-day consumption frequency. Besides, we have collected socio-demographic data and academic scores of these people. Most of the students interviewed take a deficient breakfast since only 4.88% have a complete breakfast. The girls aged 15-17 years are those taking the poorest quality breakfast since 8.33% of them skip this meal. 68.29% take breakfasts which quality may be improved. The breakfast quality is directly related with the mean score obtained during the course 2003-04. This relationship is not so clear-cut when the different mandatory subjects in the different academic orientations are considered since it depends on the type of subject (comprehension, memory, concentration, physical activity...). The population studied consumes a poor breakfast, which may affect the academic outcomes, especially those for certain subjects.

    Background: In the United States, 17% of children are currently obese. Increasing feelings of fullness may prevent excessive energy intake, lead to better diet quality, and promote long-term maintenance of healthy weight. Objective: The purpose of this study was to develop a fullness-rating tool (aim 1) and to determine whether a high-protein (HP), high-fiber (HF), and combined HP and HF (HPHF) breakfast increases preschoolers' feelings of fullness before (pre) and after (post) breakfast and pre-lunch, as well as their diet quality, as measured by using a composite diet quality assessment tool, the Revised Children's Diet Quality Index (aim 2). Methods: Children aged 4 and 5 y ( n = 41; 22 girls and 19 boys) from local Head Start centers participated in this randomized intervention trial. Sixteen percent of boys and 32% of girls were overweight or obese. After the baseline week, children rotated through four 1-wk periods of consuming ad libitum HP (19-20 g protein), HF (10-11 g fiber), HPHF (19-21 g protein, 10-12 g fiber), or usual (control) breakfasts. Food intake at breakfast was estimated daily, and for breakfast, lunch, and snack on day 3 of each study week Student's t tests and ANOVA were used to determine statistical differences. Results: Children's post-breakfast and pre-lunch fullness ratings were ≥1 point higher than those of pre-breakfast (aim 1). Although children consumed, on average, 65 kcal less energy during the intervention breakfasts ( P diet quality (12%) was calculated for the HP and HF breakfasts ( P diet quality. Serving HP or HF breakfasts may be valuable in improving diet quality without lowering feelings of satiation or satiety.

    In 1993, in Peru, the Institute of Nutritional Research conducted two studies in Huaraz in the Andean region to evaluate the educational and nutritional impact of the government's School Breakfast Program. The school breakfast included a small cake and a glass of Amilac (similar in taste and color to milk), which provided 30% of each child's energy requirements, 60% of recommended dietary allowances for minerals and vitamins, and 100% of dietary iron needs. A case control study examined the effects of breakfast on cognition among 54 elementary schoolchildren 9-11 years old. It found that the school breakfast did not have a significant effect on the children's performance in the Number Discrimination, Peabody Picture Vocabulary Test, Raven Progressive Matrices, or Reaction Time tests. Children nutritionally at risk who received the placebo had significantly slower short-term memory scanning than their counterparts who received the breakfast. The no-risk placebo group exhibited more rapid discrimination between visual stimuli than the no-risk breakfast group. A field evaluation of the program in 10 rural schools, which were randomly assigned to a treatment or control condition, was conducted. In terms of energy, protein, and iron intake, the children in the case and control conditions were not significantly different. The children tended to be either very stunted or overweight. School attendance increased 0.58 points in the experimental group, while it decreased by 2.92 points in the control group (p 0.05). When both groups received the breakfast, attendance rates increased significantly in both groups (p 0.05). Vocabulary was sensitive to the effects of the breakfast. Specifically, the greater the child's weight, the higher his/her vocabulary test scores (p 0.05). These findings suggest that the brain is sensitive to decreases in the short-term availability of nutrients, and that an overnight and morning fast produces a physiological state accompanied by changes in

    Food volume could influence both the portions that people take and the amount that they eat, but these effects have had little investigation. The influence of food volume was tested by systematically reducing the flake size of a breakfast cereal so that the cereal was more compact and the same weight filled a smaller volume. In a crossover design, 41 adults ate cereal for breakfast once a week for four weeks during 2011-2012. The cereal was either standard wheat flakes or th...

    Two surface base build-up scenarios are presented in order to help visualize the mission and to serve as a basis for trade studies. In the first scenario, direct manned landings on the Martian surface occur early in the missions and scientific investigation is the main driver and rationale. In the second scenario, early development of an infrastructure to exploite the volatile resources of the Martian moons for economic purposes is emphasized. Scientific exploration of the surface is delayed at first, but once begun develops rapidly aided by the presence of a permanently manned orbital station

    School-based breakfast provision is increasingly being seen as a means of improving educational performance and dietary behaviour amongst children. Furthermore, recognition is growing that breakfast provision offers potential as a means of addressing social inequalities in these outcomes. At present however, the evidence base on the effectiveness of breakfast provision in bringing about these improvements is limited. This paper describes the research design of a large scale evaluation of the effectiveness of the Welsh Assembly Government's Primary School Free Breakfast Initiative. A cluster randomised trial, with school as the unit of randomisation was used for the outcome evaluation, with a nested qualitative process evaluation. Quantitative outcome measures included dietary habits, attitudes, cognitive function, classroom behaviour, and school attendance. The study recruited 111 primary schools in Wales, of which 56 were randomly assigned to control condition and 55 to intervention. Participants were Year 5 and 6 students (aged 9-11 years) in these schools. Data were collected for all 111 schools at each of three time points: baseline, 4 month and 12 month follow-up. This was achieved through a repeated cross-sectional survey of approximately 4350 students on each of these occasions. Of those students in Year 5 at baseline, 1975 provided data at one or both of the follow-ups, forming a nested cohort. The evaluation also included a nested process evaluation, using questionnaires, semi-structured interviews and case studies with students, school staff, and local authority scheme coordinators as key informants. An overview of the methods used for the evaluation is presented, providing an example of the feasibility of conducting robust evaluations of policy initiatives using a randomised trial design with nested process evaluation. Details are provided of response rates and the flow of participants. Reflection is offered on methodological issues encountered at

    Full Text Available A considerable amount of research suggests that breakfast omission and the frequent use of caffeinated energy drinks may be associated with undesirable effects, and particularly so in children and adolescents. The current paper presents cross-sectional and longitudinal data from the Cornish Academies Project to investigate the effects of consuming energy drinks and missing breakfast on stress, anxiety, and depression in a cohort of secondary school children from the South West of England. Questionnaires were administered at two time-points (spaced six months apart to collect information relating to diet and lifestyle over the previous six months, demographic and school data were acquired through the School Information Management System, and single-item measures of stress, anxiety, and depression were administered at the second time-point only. Associations between breakfast and energy drink consumption and stress, anxiety, and depression were investigated, and a multivariate approach was taken so that additional variance from diet, demography, and lifestyle could be controlled for statistically. Cross-sectional analyses showed that breakfast omission was consistently associated with negative outcomes, and that this was largely observed for both those who frequently consumed energy drinks and those who did not. However, cross-lag analyses showed that neither breakfast omission or energy drink consumption, alone or in combination, was predictive of stress, anxiety, or depression at six-month follow-up. This suggests that associations between breakfast and mental health may be bi-directional rather than breakfast being the causal factor.

    The purpose of this study was to examine whether the frequency of breakfast consumption was related to academic performance in healthy Korean adolescents. We analyzed data from the seventh Korea Youth Risk Behavior Web-based Survey conducted in 2011, in which 75,643 adolescents from school grades 7-12 participated. We assessed the association between the frequency of breakfast consumption (per week) and academic performance using multivariate logistic regression analysis after adjusting for covariates such as age, body mass index, frequency of smoking, frequency of drinking, parents' education level, family economic status, frequency of vigorous physical activity (PA), frequency of moderate PA, frequency of muscular strength exercises, and level of mental stress. For male adolescents, the odds ratios (ORs) for achieving average or higher academic performance according to the breakfast frequency per week were once per week, 1.004 (P=0.945); twice per week, 0.915 (P=0.153); 3 days per week, 0.928 (P=0.237); 4 days per week, 1.087 (P=0.176); 5 days per week, 1.258 (Pacademic performance according to the breakfast frequency were once per week, 1.068 (P=0.320); twice per week, 1.140 (P=0.031); 3 days per week, 1.179 (P=0.004); 4 days per week, 1.339 (Pacademic performance in both male and female healthy adolescents in Korea.

    Research on young healthy samples suggests that low glycaemic load foods can confer benefits for cognitive performance. The aim was to examine the effects of type 2 diabetes on cognitive function, and to investigate whether consumption of low glycaemic load breakfasts affects cognitive function in adults with type 2 diabetes. Memory, psychomotor skill and executive function were examined at two morning test sessions in 24 adults with type 2 diabetes and 10 adults with normal glucose tolerance (NGT) aged 45-77 years without dementia after water, low, and high glycaemic load breakfasts were consumed in accordance with a crossover, counterbalanced design. The type 2 diabetes and NGT groups were matched for education, depression, and IQ. Type 2 diabetes was associated with impairments in verbal memory, spatial memory, psychomotor skill, and executive function compared to adults with NGT. Consumption of the three breakfast conditions did not impact on cognitive performance in the type 2 diabetes or NGT participants. Abnormalities in glucose tolerance such as type 2 diabetes can have demonstrable negative effects on a range of cognitive functions. However, there was no evidence that low GL breakfasts administered acutely could confer benefits for cognitive function (ClincalTrials.gov identifier, NCT01047813).

    Full Text Available Patients on treatment with levothyroxine (T4 are informed to take this drug in the morning, at least 30 min before having breakfast. A significant decrease of T4 absorption was reported, in fact, when T4 solid formulations are taken with food or coffee. According to preliminary clinical study reports, administration of T4 oral solution appears to be less sensitive to the effect of breakfast beverages on oral bioavailability. In the present study, stability of T4 oral solution added to breakfast beverages was investigated. A 1 mL ampoule of single-dose Tirosint® oral solution (IBSA Farmaceutici Italia, Lodi, Italy was poured into defined volumes of milk, tea, coffee, and coffee with milk warmed at 50 °C, as well as in orange juice at room temperature. Samples were sequentially collected up to 20 min and analyzed by validated liquid chromatography-tandem mass spectrometry (LC-MS/MS methods. The results of the study demonstrated that T4 is stable in all beverages after 20 min incubation. Demonstration of T4 stability is a prerequisite for a thorough evaluation of the effect of breakfast beverages on the bioavailability of T4 given as oral solution and for a better understanding of the reasons underlying a decreased T4 bioavailability administered as solid formulations.

    To examine the association between breakfast skipping and type of breakfast consumed with overweight/obesity, abdominal obesity, other cardiometabolic risk factors and the metabolic syndrome (MetS). Cross-sectional. Three breakfast groups were identified, breakfast skippers (BS), ready-to-eat-cereal (RTEC) consumers and other breakfast (OB) consumers, using a 24 h dietary recall. Risk factors were compared between the breakfast groups using covariate-adjusted statistical procedures. The 1999–2006 National Health and Nutrition Examination Survey, USA. Young adults (20–39 years of age). Among these young adults (n 5316), 23.8% were BS, 16.5% were RTEC consumers and 59.7% were OB consumers. Relative to the BS, the RTEC consumers were 31%, 39%, 37%, 28%, 23%, 40% and 42% less likely to be overweight/obese or have abdominal obesity, elevated blood pressure, elevated serum total cholesterol, elevated serum LDL-cholesterol, reduced serum HDL-cholesterol or elevated serum insulin, respectively. Relative to the OB consumers, the BS were 1.24, 1.26 and 1.44 times more likely to have elevated serum total cholesterol, elevated serum LDL-cholesterol or reduced serum HDL-cholesterol, respectively. Relative to the OB consumers, the RTEC consumers were 22%, 31% and 24% less likely to be overweight/ obese or have abdominal obesity or elevated blood pressure, respectively. No difference was seen in the prevalence of the MetS by breakfast skipping or type of breakfast consumed. Results suggest that consumption of breakfast, especially that included an RTEC, was associated with an improved cardiometabolic risk profile in U.S. young adults. Additional studies are needed to determine the nature of these relationships.

    Short-term impacts of breakfast consumption on diet quality and cognitive functioning have been reported, but more evidence is needed to draw causal inferences about long-term impacts of school breakfast on indicators of school engagement and academic achievement. To estimate the impact of a Breakfast in the Classroom (BIC) program on School Breakfast Program participation, school attendance, and academic achievement. This quasi-experimental study included a sample of 446 public elementary schools from a large, urban US school district that served predominantly low-income, racial/ethnic minority students. A total of 257 schools (57.6%) implemented a BIC program during the 2012-2013 academic year, whereas 189 (42.4%) did not. School- and grade-level data from 2012-2013 and grade-level achievement data from the prior year were collected from school district records across the elementary schools. Hypotheses that a BIC program would improve school breakfast participation at the school level, school attendance at the grade level (kindergarten through sixth grade), and academic achievement at the grade level (second through sixth grades) were tested using propensity score weights to adjust for demographic differences between the BIC and non-BIC schools. The BIC program was linked with increased breakfast participation during the academic year (F10,414=136.90, Pperforming attendance analyses in the subset of grade levels for which achievement data were available, results were mostly consistent, although there was a group × time interaction (F10,1891=1.94, P=.04) such that differences between least squares means in the BIC vs non-BIC groups did not reach statistical significance at every month. There were no group differences in standardized test performance in math (57.9% in the BIC group vs 57.4% in the non-BIC group; F1,1890=0.41, P=.52) or reading (44.9% in the BIC group vs 44.7% in the non-BIC group; F1,1890=0.15, P=.70).

    Full Text Available Scenario Planning has been increasingly used, from its introduction to the decision process as effective tools to test decisions, and improve performance in a dynamic environment (Chermack, 2005. The purpose of this article is to demonstrate the potential of an experimental Scenario Planning Model to mobilize, encourage and add more content to the organization’s decision making process – mainly with respect to Strategic Plans of two governmental institutions, a pharmaceutical company and a technology education foundation.  This study describes the application stages of a hybrid scenario-planning model – herein referred to as Planning as Learning – via action-research, showing the scenarios resulting from the experiment and describes the main results of an assessment of such practice. In order to do that, two well-established Scenario Planning models (Prospective school and Shell’s model were analyzed. They were used as a reference for the proposition and application of an experimental model in the two study objects. A questionnaire was used to assess the technique impact. It was possible to obtain high levels of reliability. In-depth interviews were also conducted with the participants. At the end, the results confirmed the model efficiency as a basis for decision making in the competitive environment in which the two institutions are inserted, also to encourage the learning process as a group, as observed throughout the work.

  11. Scenarios for Gluino Coannihilation

    Ellis, John; Luo, Feng; Olive, Keith A

    2016-01-01

    We study supersymmetric scenarios in which the gluino is the next-to-lightest supersymmetric particle (NLSP), with a mass sufficiently close to that of the lightest supersymmetric particle (LSP) that gluino coannihilation becomes important. One of these scenarios is the MSSM with soft supersymmetry-breaking squark and slepton masses that are universal at an input GUT renormalization scale, but with non-universal gaugino masses. The other scenario is an extension of the MSSM to include vector-like supermultiplets. In both scenarios, we identify the regions of parameter space where gluino coannihilation is important, and discuss their relations to other regions of parameter space where other mechanisms bring the dark matter density into the range allowed by cosmology. In the case of the non-universal MSSM scenario, we find that the allowed range of parameter space is constrained by the requirement of electroweak symmetry breaking, the avoidance of a charged LSP and the measured mass of the Higgs boson, in parti...

The other scenario is an extension of the MSSM to include vector-like supermultiplets. In both scenarios, we identify the regions of parameter space where gluino coannihilation is important, and discuss their relations to other regions of parameter space where other mechanisms bring the dark matter density into the range allowed by cosmology. In the case of the non-universal MSSM scenario, we find that the allowed range of parameter space is constrained by the requirement of electroweak symmetry breaking, the avoidance of a charged LSP and the measured mass of the Higgs boson, in particular, as well as the appearance of other dark matter (co)annihilation processes. Nevertheless, LSP masses m{sub χ}≲8 TeV with the correct dark matter density are quite possible. In the case of pure gravity mediation with additional vector-like supermultiplets, changes to the anomaly-mediated gluino mass and the threshold effects associated with these states can make the gluino almost degenerate with the LSP, and we find a similar upper bound.

  13. Regional climate change scenarios

    Because studies of the regional impact of climate change need higher spatial resolution than that obtained in standard global climate change scenarios, developing regional scenarios from models is a crucial goal for the climate modelling community. The zoom capacity of ARPEGE-Climat, the Meteo-France climate model, allows use of scenarios with a horizontal resolution of about 50 km over France and the Mediterranean basin. An IPCC-A2 scenario for the end of the 21. century in France shows higher temperatures in each season and more winter and less summer precipitation than now. Tuning the modelled statistical distributions to observed temperature and precipitation allows us to study changes in the frequency of extreme events between today's climate and that at the end of century. The frequency of very hot days in summer will increase. In particular, the frequency of days with a maximum temperature above 35 deg C will be multiplied by a factor of 10, on average. In our scenario, the Toulouse area and Provence might see one quarter of their summer days with a maximum temperature above 35 deg C. (author)

    The School Breakfast Program is an important component of the nutritional safety net and has been linked to positive changes in meal patterns and nutritional outcomes. By offering a breakfast, which for low-income children is available either at no cost or reduced price, the program also has the potential to increase household food security. This study examined the relationship between availability of the School Breakfast Program and household food security among low-income third-grade students by using data from the Early Childhood Longitudinal Survey-Kindergarten Cohort. The primary sample included 3010 students. Availability of school breakfast was assessed by surveys of school administrators. Food security was assessed by parents' reports by using the standard 18-item food security scale and considering 2 different food security thresholds. A probit model was estimated to measure the relationship between school breakfast availability and household food security while controlling for a range of other characteristics. Access to school breakfast reduced the risk of marginal food insecurity but not the risk of food insecurity at the standard threshold. That is, the program appeared beneficial in offsetting food-related concerns among at-risk families, although not necessarily in alleviating food insecurity once hardships had crossed the food insecurity threshold. Increasing the availability of school breakfast may be an effective strategy to maintain food security among low-income households with elementary school children.

    The macronutrient composition of a breakfast that could facilitate performance after an overnight fast remains unclear. As glucose is the brain's major energy source, the interest is in investigating meals differing in their blood glucose-raising potential. Findings vary due to unaccounted differences in glucoregulation, arousal and cortisol secretion. We investigated the effects of meals differing in glycaemic index (GI) and glycaemic load (GL) on cognition and mood in school children. A total of seventy-four school children were matched and randomly allocated either to the high-GL or low-GL group. Within each GL group, children received high-GI and low-GI breakfasts. Cognitive function (CF) and mood were measured 95-140 min after breakfast. Blood glucose and salivary cortisol were measured at baseline, before and after the CF tests. Repeated-measures ANOVA was used to identify differences in CF, mood, glucose and cortisol levels between the breakfasts. Low-GI meals predicted feeling more alert and happy, and less nervous and thirsty (P breakfast, and high-GI meals increased cortisol levels (P breakfast may help to improve learning, and of potential value in informing government education policies relating to dietary recommendations and implementation concerning breakfast.

    The objective of this study was to compare the nutritional content and healthfulness of child-targeted and "not child-targeted" breakfast cereals and to assess the predominance of added sugar in these products. We collected data on the nutritional content of 262 unique breakfast cereals found in the five largest grocery store chains in Ottawa (Ontario) and Gatineau (Quebec). We noted the first five ingredients and the number of added sugars present in each cereal from the ingredients list. The various cereal brands were then classified as either "healthier" or "less healthy" using the UK Nutrient Profile Model. We assessed each cereal to determine if it was child-targeted or not, based on set criteria. Statistical comparisons were made between child and not child-targeted cereals. 19.8% of all breakfast cereals were child-targeted, and these were significantly lower in total and saturated fat. Child-targeted cereals were significantly higher in sodium and sugar and lower in fibre and protein, and were three times more likely to be classified as "less healthy" compared to not child-targeted cereals. No child-targeted cereals were sugar-free, and sugar was the second most common ingredient in 75% of cereals. Six breakfast cereal companies had child-targeted product lines that consisted entirely of "less healthy" cereals. There is a need for regulations that restrict food marketing to children and youth under the age of 17 on packaging to reduce their appeal to this age group. Children's breakfast cereals also need to be reformulated through government-set targets, or through regulation should compliance be deemed unacceptable.

    To study the effect of breakfast timing on selected cognitive functions of elementary school students. A 2-week randomized control intervention trial. Five elementary schools. The subjects comprised 569 children, 51% of them boys, aged 11 to 13 years; the children were in grades 5 through 6 (17 classes). The subjects lived in different areas and had different socioeconomic backgrounds. Each subject was tested twice, by 2 versions of the Rey Auditory-Verbal Learning Test, 2 alternative forms of the logical memory subtest of the revised Wechsler Memory Scale, and 2 versions of the Benton Visual Retention Test. On the first test, before any nutritional intervention, the subjects were asked to complete a questionnaire about their food intake on the day of testing. Two thirds of the subjects received 200 ml of 3%-fat milk and 30 g of sugared cornflakes for the next 14 days, and all the subjects were reexamined on the 15th day. Scoring on the different tests was compared with baseline scores. After 15 days, children who ate breakfast at school scored notably higher on most of the test modules than did children who ate breakfast at home and children who did not at breakfast. Our results indicate that routinely eating breakfast 2 hours prior to being tested does not improve cognitive functions in 11- to 13-year-old elementary school students, but food supplementation 30 minutes prior to taking a test notably improves scoring. We suggest further studies on the relationship between meal content, feeding time, and scholastic performance.

    Full Text Available ABSTRACT Objective: To characterize breakfast eating among Brazilian adolescents. Methods: Food intake was estimated based on a 1-day food record of adolescents aged 10-19 years, according to the first National Diet Survey (2008-2009. Breakfast was considered as the first meal of the day eaten between 4 and 11 am. Results: Ninety-three percent of adolescents reported eating breakfast. This meal contributed to 17.7% of the daily energy intake. The most commonly consumed food groups were: coffee and tea, breads, butter/margarine, milk, cakes and cookies, packaged snacks, corn-based dishes, cheese, processed meats, and fruit juice. In the Northern region there was a higher frequency of coffee and tea and roots and tubers intake and lower frequency of milk intake than that in the other regions in the country. In the Northeastern region, the intake of corn and eggs was high; in the Southern region, there was high intake of processed meats and fruits. Adolescents from families in the first income quartile reported higher intake of coffee and tea, packaged snacks, corn, and roots and tubers intake, and lower intake of milk and dairy products. Adolescents from families in the highest income quartile reported higher intake of milk, fruit juice, cheese, and sugar-added beverages. Conclusion: In Brazil, the contribution of breakfast to daily energy intake among adolescents is low. The nutritional quality of breakfast improved with increased income. The three most frequently consumed items were coffee and tea, breads, and butter/margarine.

    Hypertension is a major public health problem. While many dietary factors affect the risk of developing hypertension, limited data are available on the association between consumption of breakfast cereal and incident hypertension. We examined the association between breakfast cereal consumption and the risk of hypertension. We prospectively analyzed data from 13,368 male participants of the Physicians' Health Study I. Consumption of breakfast cereals was estimated using an abbreviated food frequency questionnaire and incident hypertension was ascertained through yearly follow-up questionnaires. The average age of study participants was 52.4 ± 8.9 years (range 39.7-85.9) during the initial assessment of cereal intake (1981-1983). During a mean follow up of 16.3 years, 7267 cases of hypertension occurred. The crude incidence rates of hypertension were 36.7, 34.0, 31.7, and 29.6 cases/1000 person-years for people reporting breakfast cereal intake of 0, ≤1, 2-6, and ≥7 servings/week, respectively. In a Cox regression model adjusting for age, smoking, body mass index, alcohol consumption, fruit and vegetable consumption, physical activity, and history of diabetes mellitus, hazard ratios (95% CI) for hypertension were 1.0 (reference), 0.93 (0.88-0.99), 0.88 (0.83-0.94), and 0.81 (0.75-0.86) from the lowest to the highest category of cereal consumption, respectively (p for trend cereals and was observed in lean as well as overweight or obese participants. The results of this longitudinal cohort study suggest that whole grain breakfast cereal consumption confers a lower risk of hypertension in middle-aged adult males.

    The provision of school breakfast has become increasingly popular in the UK in recent years. However, UK-based studies highlighting the views of parents, children, and school staff on school breakfast clubs are lacking. The current study set out to address this dearth in the literature by investigating the views of these key user and stakeholder groups on breakfast clubs within the North East of England. Fourteen parents, 21 children, and 17 school staff were recruited from four primary schools where breakfast clubs were available on site. Parents and school staff took part in semistructured interviews and children participated in focus groups, through which the advantages and disadvantages of breakfast clubs were discussed. Thematic analysis revealed that breakfast clubs provided children with a settled and enjoyable start to the school day. As well as providing children with a healthy and varied breakfast meal and unique opportunities for social interaction, breakfast clubs were recognized as an integral part of the school system that offered support to parents, particularly those who worked and relied on breakfast clubs as a means of affordable and reliable childcare. The few disadvantages identified related to practical issues such as a lack of adherence to school food standards, breakfast club staff missing class preparation time and concerns that some children were being excluded from participating in breakfast clubs particularly due to costs associated with attendance. The findings are discussed in relation to the School Food Plan, and areas for further investigation are proposed.

    Possible future climate changes in California are investigated from a varied set of climate change model simulations. These simulations, conducted by three state-of-the-art global climate models, provide trajectories from three greenhouse gas (GHG) emission scenarios. These scenarios and the resulting climate simulations are not “predictions,” but rather are a limited sample from among the many plausible pathways that may affect California’s climate. Future GHG concentrations are uncertain because they depend on future social, political, and technological pathways, and thus the IPCC has produced four “families” of emission scenarios. To explore some of these uncertainties, emissions scenarios A2 (a medium-high emissions) and B1 (low emissions) were selected from the current IPCC Fourth climate assessment, which provides several recent model simulations driven by A2 and B1 emissions. The global climate model simulations addressed here were from PCM1, the Parallel Climate Model from the National Center for Atmospheric Research (NCAR) and U.S. Department of Energy (DOE) group, and CM2.1 from the National Oceanic and Atmospheric Administration (NOAA) Geophysical Fluids Dynamics Laboratory (GFDL).

    The U.S. Geological Survey and several partners operate a program called Science Application for Risk Reduction (SAFRR) that produces (among other things) emergency planning scenarios for natural disasters. The scenarios show how science can be used to enhance community resiliency. The SAFRR Tsunami Scenario describes potential impacts of a hypothetical, but realistic, tsunami affecting California (as well as the west coast of the United States, Alaska, and Hawaii) for the purpose of informing planning and mitigation decisions by a variety of stakeholders. The scenario begins with an Mw 9.1 earthquake off the Alaska Peninsula. With Pacific basin-wide modeling, we estimate up to 5m waves and 10 m/sec currents would strike California 5 hours later. In marinas and harbors, 13,000 small boats are damaged or sunk (1 in 3) at a cost of $350 million, causing navigation and environmental problems. Damage in the Ports of Los Angeles and Long Beach amount to $110 million, half of it water damage to vehicles and containerized cargo. Flooding of coastal communities affects 1800 city blocks, resulting in $640 million in damage. The tsunami damages 12 bridge abutments and 16 lane-miles of coastal roadway, costing $85 million to repair. Fire and business interruption losses will substantially add to direct losses. Flooding affects 170,000 residents and workers. A wide range of environmental impacts could occur. An extensive public education and outreach program is underway, as well as an evaluation of the overall effort.

    Full Text Available Shift work is a risk factor for chronic diseases such as Type 2 diabetes. Food choice may play a role, however simply eating at night when the body is primed for sleep may have implications for health. This study examined the impact of consuming a big versus small snack at night on glucose metabolism. N = 31 healthy subjects (21–35 y; 18 F participated in a simulated nightshift laboratory study that included one baseline night of sleep (22:00 h-07:00 h and one night awake with allocation to either a big snack (2100 kJ or small snack (840 kJ group. The snack was consumed between 00:00–00:30 h and consisted of low fat milk, a sandwich, chips and fruit (big snack or half sandwich and fruit (small snack. Subjects ate an identical mixed meal breakfast (2100 kJ at 08:30 h after one full night of sleep and a simulated nightshift. Interstitial glucose was measured continuously during the entire study using Medtronic Continual Glucose Monitors. Only subjects with identical breakfast consumption and complete datasets were analysed (N = 20. Glucose data were averaged into 5-minute bins and area under the curve (AUC was calculated for 90 min post-breakfast. Pre-breakfast, glucose levels were not significantly different between Day1 and Day2, nor were they different between snack groups (p > 0.05. A snack group by day interaction effect was found (F1,16 = 5.36, p = 0.034 and post-hocs revealed that in the big snack group, AUC response to breakfast was significantly higher following nightshift (Day2 compared to Day1 (p = 0.001. This translated to a 20.8% (SEM 5.6 increase. AUC was not significantly different between days in the small snack group. Consuming a big snack at 00:00 h impaired the glucose response to breakfast at 08:30 h, compared to a smaller snack. Further research in this area will inform dietary advice for shift workers, which could include recommendations on how much to eat as well as content.

    Full Text Available Abstract Background School-based breakfast provision is increasingly being seen as a means of improving educational performance and dietary behaviour amongst children. Furthermore, recognition is growing that breakfast provision offers potential as a means of addressing social inequalities in these outcomes. At present however, the evidence base on the effectiveness of breakfast provision in bringing about these improvements is limited. Methods/Design This paper describes the research design of a large scale evaluation of the effectiveness of the Welsh Assembly Government's Primary School Free Breakfast Initiative. A cluster randomised trial, with school as the unit of randomisation was used for the outcome evaluation, with a nested qualitative process evaluation. Quantitative outcome measures included dietary habits, attitudes, cognitive function, classroom behaviour, and school attendance. The study recruited 111 primary schools in Wales, of which 56 were randomly assigned to control condition and 55 to intervention. Participants were Year 5 and 6 students (aged 9–11 years in these schools. Data were collected for all 111 schools at each of three time points: baseline, 4 month and 12 month follow-up. This was achieved through a repeated cross-sectional survey of approximately 4350 students on each of these occasions. Of those students in Year 5 at baseline, 1975 provided data at one or both of the follow-ups, forming a nested cohort. The evaluation also included a nested process evaluation, using questionnaires, semi-structured interviews and case studies with students, school staff, and local authority scheme coordinators as key informants. Discussion An overview of the methods used for the evaluation is presented, providing an example of the feasibility of conducting robust evaluations of policy initiatives using a randomised trial design with nested process evaluation.

    Full Text Available Objective: To review systematically the evidence on breakfast cereal consumption and obesity in children and adolescents and assess whether the regular consumption of breakfast cereals could help to prevent excessive weight gain. Methods: A systematic review and meta-analysis of studies relating breakfast cereal consumption to BMI, BMI z-scores and prevalence of obesity as the outcomes. Results: 14 papers met the inclusion criteria. The computed effect size for mean BMI between high consumers and low or non-consumers over all 25 study subgroups was -1.13 kg/m2 (95% CI -0.81, -1.46, p Conclusion: Overall, the evidence reviewed is suggestive that regular consumption of breakfast cereals results in a lower BMI and a reduced likelihood of being overweight in children and adolescents. However, more evidence from long-term trials and investigations into mechanisms is needed to eliminate possible confounding factors and determine causality.

    The gamma irradiation as treatment for control of the immature stages of fruit flies, C. capitata and A. fraterculus in papaya fruits, cultivar Sunrise Solo is studied. The gamma rays attenuation was observed by one and two papaya fruits placed between source and infested fruit, and this changed the radiation doses required to obtain mortality in eggs and larvae of the Medfly. The efficacy of irradiation was higher when the infested papayas were packed in paper box. The radiation dose determined using the Probit 9 concept, for immature stages mortality of C. capitata was 107,74 Gy and for A. fraterculus was 50,82 Gy. The sterilizing doses for adults of C. capitata and D. fraterculus, irradiated as pupae, was 60 Gy and 40 Gy, respectively. (author)

    Regular consumption of a well balanced breakfast is a pre-requisite for normal growth and child development, along with the acquisition of proper eating habits. The family environment is crucial place where children learn such patterns of behaviour that form the basis for their development. To determine how family factors affect the regular eating of breakfast and types of foodstuffs consumed in primary school pupils, including food purchases made from vending machines and school tuck shops. Subjects were 836 pupils (435 girls and 401 boys, aged 6 - 13) from Warsaw and the surrounding areas. Appropriate socio-demographic data and relevant eating habits were obtained from direct interviewing of the subjects by means of a custom designed questionnaire. Statistical analyses were performed by the Kohonen type cluster analysis model and Chi-square test (Chi(2)); (p≤0.05). Three clusters of pupils were identified by their differing socio-demographics and eating habits (eg. rates of breakfast consumption, buying from vending machines or school tuck shops). The first and third clusters were mainly pupils from two-parent families with parents proportionally spending similar times at work, where respective breakfast (87% and 91%) and second breakfast (77% and 72%) consumption rates were also similar together with food shopping rates during school time (respectively 69% and 63%). Pupils with single-parents, multi-generation families or if both parents were profession- ally active, predominated in the second cluster. These ate breakfast (73%) and second breakfast (67%) more rarely, but more frequently shopped for food at school (84%). A small number of pupils had a packed second breakfast from home, rarely ate sandwiches, fruit and/or vegetables and dairy products but ate more sweets, sweet rolls and savoury snacks. However, a large number of subjects bought sandwiches, fresh fruit and/or vegetables and fast-food at school. Family factors were found to affect eating habits

    This report documents the results of two Hanford groundwater scenario studies. The first study examines the hydrologic impact of increased groundwater recharge resulting from agricultural development in the Cold Creek Valley located west of the Hanford Reservation. The second study involves recovering liquid radioactive waste which has leaked into the groundwater flow system from a hypothetical buried tank containing high-level radioactive waste. The predictive and control capacity of the onsite Hanford modeling technology is used to evaluate both scenarios. The results of the first study indicate that Cold Creek Valley irrigationis unlikely to cause significant changes in the water table underlying the high-level waste areas or in the movement of radionuclides already in the groundwater. The hypothetical tank leak study showed that an active response (in this case waste recovery) can be modeled and is a possible alternative to passive monitoring of radionuclide movement in the unlikely event that high-level waste is introduced into the groundwater

    Full Text Available Unhealthy dietary pattern increases the risk of obesity and metabolic disorders in growing children and adolescents. However, the way the habitual pattern of breakfast consumption influences body composition and risk of obesity in adolescents is not well defined. Thus, the aim of the present study was to assess any associations between breakfast consumption practices and body composition profiles in 236 apparently healthy adolescents aged 12 to 19 years. A self-administered questionnaire on dietary behaviour and lifestyle practices and a dietary food frequency questionnaire were used. Body composition and adiposity indices were determined using standard anthropometric measurement protocols and dual energy χ-ray absorptiometry (DXA. Mean age of the participants was 15.3±1.9 years. The majority of participants (71.2% fell in the normal body mass index (BMI ranges. Breakfast consumption patterns showed that only half of the participants (50% were consuming breakfast daily. Gender-specific multivariate analyses (ANCOVA showed that in both boys and girls, those eating breakfast at least 5 times a week had significantly lower body weight, body mass index (BMI, BMI z-scores, waist circumference, body fat mass and percent body fat (%BF compared to infrequent breakfast eaters, after adjustment for age, household income, pubertal status, eating-out and snacking practices, daily energy intakes, and daily physical activity levels. The present findings indicate that infrequent breakfast consumption is associated with higher body adiposity and abdominal obesity. Therefore, daily breakfast consumption with healthy food choices should be encouraged in growing children and adolescents to prevent adiposity during these critical years of growth.

    This study examined the association of breakfast consumption, and the type of breakfast consumed, with body mass index (BMI; kg/m(2)) and prevalence rates and odds ratios (OR) of overweight/obesity among Canadian adults. These associations were examined by age group and sex. We used data from non-pregnant, non-lactating participants aged ≥ 18 years (n = 12,377) in the Canadian Community Health Survey Cycle 2.2, a population-based, nationally-representative, cross-sectional study. Height and weight were measured, and BMI was calculated. Breakfast consumption was self-reported during a standardized 24-h recall; individuals were classified as breakfast non-consumers, consumers of breakfasts that included ready-to-eat cereal (RTEC) or as other breakfast consumers. Mean BMI and prevalence and OR of overweight/obesity (BMI ≥ 25) were compared among breakfast groups, with adjustment for sociodemographic variables (including age, sex, race, marital status, food security, language spoken at home, physical activity category, smoking, education level and supplement use). For the entire sample, mean BMI was significantly lower among RTEC-breakfast consumers than other breakfast consumers (mean ± SE 26.5 ± 0.2 vs. 27.1 ± 0.1 kg/m(2)), but neither group differed significantly from breakfast non-consumers (27.1 ± 0.3 kg/m(2)). Similar results were seen in women only, but BMI of men did not differ by breakfast category. Overweight/obesity prevalence and OR did not differ among breakfast groups for the entire sample or for all men and women separately. When examined by sex and age group, differences were inconsistent, but tended to be more apparent in women than men. Among Canadian adults, breakfast consumption was not consistently associated with differences in BMI or overweight/obesity prevalence.

  5. Ontario demand response scenarios

    2005-09-01

    Strategies for demand management in Ontario were examined via 2 scenarios for a commercial/institutional building with a normal summertime peak load of 300 kW between 14:00 and 18:00 during a period of high electricity demand and high electricity prices. The first scenario involved the deployment of a 150 kW on-site generator fuelled by either diesel or natural gas. The second scenario involved curtailing load by 60 kW during the same periods. Costs and benefits of both scenarios were evaluated for 3 groups: consumers, system operators and society. Benefits included electricity cost savings, deferred transmission capacity development, lower system prices for electricity, as well as environmental changes, economic development, and a greater sense of corporate social responsibility. It was noted that while significant benefits were observed for all 3 groups, they were not substantial enough to encourage action, as the savings arising from deferred generation capacity development do not accrue to individual players. The largest potential benefit was identified as lower prices, spread across all users of electricity in Ontario. It was recommended that representative bodies cooperate so that the system-wide benefits can be reaped. It was noted that if 10 municipal utilities were able to have 250 commercial or institutional customers engaged in distributed response, then a total peak demand reduction of 375 MW could be achieved, representing more than 25 per cent of Ontario's target for energy conservation. It was concluded that demand response often involves the investment of capital and new on-site procedures, which may affect reactions to various incentives. 78 refs., 10 tabs., 5 figs

    Existing methods are inadequate for developing aggregate (regional and global) and long-term (several decades) passenger transport demand scenarios, since they are mainly based on simple extensions of current patterns rather than causal relationships that account for the competition among transport modes (aircraft, automobiles, buses and trains) to provide transport services. The demand scenario presented in this paper is based on two empirically proven invariances of human behavior. First, transport accounts for 10 to 15 percent of household total expenditures for those owning an automobile, and around 5 percent for non-motorized households on average (travel money budget). Second, the mean time spent traveling is approximately one hour per capita per day (travel time budget). These two budgets constraints determine the dynamics of the scenario: rising income increases per capita expenditure on travel which, in turn, increase demand for mobility. Limited travel time constraints travelers to shift to faster transport systems. The scenario is initiated with the first integrated historical data set on traffic volume in 11 world regions and the globe from 1960 to 1990 for all major modes of motorized transport. World average per capita traffic volume, which was 1,800 kilometers in 1960 and 4,2090 in 1990, is estimated to rise to 7,900 kilometers in 2020 - given a modest average increase in Gross World Product of 1.9% per year. Higher economic growth rates in Asian regions result in an increase in regional per capita traffic volume up to a factor of 5.3 from 1990 levels. Modal splits continue shifting to more flexible and faster modes of transport. At one point, passenger cars can no longer satisfy the increasing demand for speed (i.e. rising mobility within a fixed time budget). In North America it is estimated that the absolute traffic volume of automobiles will gradually decline starting in the 2010s. (author) 13 figs., 6 tabs., 35 refs.

    Lack of breakfast has been implicated as a factor contributing to children's poor diets and school performance. Breakfast-club schemes, where children are provided with breakfast in school at the start of the school day, have been initiated by the Department of Health in schools throughout England, UK. The aim of the present study was to compare the energy and nutrient intakes of schoolchildren who attended breakfast clubs (attendee subjects) with those who did not (control subjects). Three different schools were studied, involving a total of 111 children aged between 9 and 15 years. There were fifty-nine attendee and fifty-two control subjects. The two groups were matched for eligibility for school meals. All subjects completed a 3 d weighed food diary for estimation of nutrient intake. Height and weight were measured and BMI calculated. Nutrient intake data were analysed using a general linear model with age as a covariate. The demographic and anthropometric characteristics of the attendee and control subjects were similar. Children who attended breakfast clubs had significantly greater intakes of fat (% energy), saturated fat (% energy) and Na than control subjects. Thus, in these schools breakfast-club participation was not associated with superior nutrient intake or improvements in dietary pattern.

    The main objective of the study is to analyze whether students of Compulsory Secondary Education (ESO) of Badajoz city known foods that are part of a healthy breakfast. It also intends to see the relationship of this knowledge with lifestyle habits and academic performance. A representative sample of 1197 secondary students in the city of Badajoz (Spain) (50.1% female) was calculated their Body Mass Index (BMI) and were asked to fill in a questionnaire, previously validated in a pilot study, which included sociodemographic items as well as others related with life style habits. They were also asked to choose among a series of food, which of them were a part of a healthy breakfast. 49.2% of adolescents know foods which are a part of a healthy breakfast. Very low correlations were obtained between all the variables analyzed and knowledge of foods that make up a healthy breakfast. However, within a few variables are significant differences (Phabit, passing lot of time with friends, who have been on a diet, make less than 3 meals a day and spend less than 10minutes for breakfast and know the amount of fruit that should be consumed daily. Life style habits of adolescents are not related to the knowledge about the foods that are part of a healthy breakfast. Copyright © 2013 SEEN. Published by Elsevier Espana. All rights reserved.

    Fast food consumption and skipping breakfast has been increasingly prevalent among high school adolescents in recent years. These unhealthy food habits are considered as risk factors of chronic diseases among adolescents and adults. To determine the consumption amount of fast food, breakfast, and some associated factors in adolescents. In this cross-sectional study in 2015, 553 adolescent students aged 14-18 years were randomly selected among high schools of Sanandaj, Iran. Demographic data and also consumption amount of fast food and breakfast in adolescents in addition to the related factors were studied. Data were collected using a researcher-made questionnaire which its reliability and validity were measured by five experts and analyzed with SPSS-16 by Chi-square test and ANOVA. The results show that 69.8 % of subjects consume fast food at least once a week. Fast food and breakfast consumption is related significantly to subjects' fathers' occupation respectively (p=0.005), (p=0.006). Eating breakfast is significantly higher among boys than girls (pfast food consumption are: their own and their families and friends' interest and accompaniment, advertisement, close proximity of school and home to fast food stores. The consumption of fast food is high among Iranian adolescents. It correlates significantly with variables including father's occupation and all of the associated factors. Breakfast consumption correlates significantly with adolescents' age and gender, as well as parents' occupation and educational level.

    Breakfast consumption is recommended, despite inconclusive evidence of health benefits. The study's aim was to ascertain whether eating breakfast (EB) or omitting breakfast (OB) affects energy intake, energy expenditure, and circulating insulin, glucose, and lipid concentrations in healthy women. In a randomized crossover trial, 10 women [x+/-SD body mass index (BMI; in kg/m2): 23.2+/-1.4] underwent two 14-d EB or OB interventions separated by a 2-wk interval. In the EB period, subjects consumed breakfast cereal with 2%-fat milk before 0800 and a chocolate-covered cookie between 1030 and 1100. In the OB period, subjects consumed the cookie between 1030 and 1100 and the cereal and milk between 1200 and 1330. Subjects then consumed 4 additional meals with content similar to usual at predetermined times later in the day and recorded food intake on 3 d during each period. Fasting and posttest meal glucose, lipid, and insulin concentrations and resting energy expenditure were measured before and after each period. Reported energy intake was significantly lower in the EB period (P=0.001), and resting energy expenditure did not differ significantly between the 2 periods. OB was associated with significantly higher fasting total and LDL cholesterol than was EB (3.14 and 3.43 mmol/L and 1.55 and 1.82 mmol/L, respectively; P=0.001). The area under the curve of insulin response to the test meal was significantly lower after EB than after OB (P<0.01). OB impairs fasting lipids and postprandial insulin sensitivity and could lead to weight gain if the observed higher energy intake was sustained.

    Dietary components may affect brain function and influence behaviour by inducing the synthesis of neurotransmitters. The aim of the present study was to examine the influence of consumption of a whey protein-containing breakfast drink v. a carbohydrate drink v. control on subjective and physiological responses to mental workload in simulated work. In a randomised cross-over design, ten healthy subjects (seven women, median age 26 years, median BMI 23 kg/m(2)) participated in a single-blinded, placebo-controlled study. The subjects performed demanding work-like tasks after having a breakfast drink high in protein (HP) or high in carbohydrate (HC) or a control drink on separate sessions. Subjective states were assessed using the NASA Task Load Index (NASA-TLX), the Karolinska sleepiness scale (KSS) and the modified Profile of Mood States. Heart rate was recorded during task performance. The ratio of plasma tryptophan (Trp) to the sum of the other large neutral amino acids (LNAA) and salivary cortisol were also analysed. The plasma Trp:LNAA ratio was 30 % higher after the test drinks HP (median 0·13 (μmol/l)/(μmol/l)) and HC (median 0·13 (μmol/l)/(μmol/l)) than after the control drink (median 0·10 (μmol/l)/(μmol/l)). The increase in heart rate was smaller after the HP (median 2·7 beats/min) and HC (median 1·9 beats/min) drinks when compared with the control drink (median 7·2 beats/min) during task performance. Subjective sleepiness was reduced more after the HC drink (median KSS - 1·5) than after the control drink (median KSS - 0·5). There were no significant differences between the breakfast types in the NASA-TLX index, cortisol levels or task performance. We conclude that a breakfast drink high in whey protein or carbohydrates may improve coping with mental tasks in healthy subjects.

    To understand perspectives of stakeholders during initial district-wide implementation of a Breakfast in the Classroom (BIC) model of the School Breakfast Program. Qualitative data were collected from twenty-nine focus groups and twenty interviews with stakeholders in a school district early in the process of implementing a BIC model of the School Breakfast Program. Ten elementary schools within a large, urban school district in the USA that served predominantly low-income, racial/ethnic minority students. Purposively selected stakeholders in elementary schools that had implemented BIC for 3-6 months: students (n 85), parents/guardians (n 86), classroom teachers (n 44), cafeteria managers (n 10) and principals (n 10). Four primary themes emerged, which were interpreted based on the Diffusion of Innovations model. School staff had changed their perceptions of both the relative disadvantages and costs related to time and effort of BIC over time; the majority of each stakeholder group expressed an appreciation for BIC; student breakfast consumption varied from day to day, related to compatibility of foods with child preferences; and stakeholders held mixed and various impressions of BIC's potential impacts. The study underscores the importance of engaging school staff and parents in discussions of BIC programming prior to its initiation to pre-emptively address concerns related to cost, relative disadvantages and compatibility with child preferences and school routines/workflow. Effectively communicating with stakeholders about positive impacts and nutritional value of the meals may improve support for BIC. These findings provide new information to policy makers, districts and practitioners that can be used to improve implementation efforts, model delivery and outcomes.

    Full Text Available In the last decade the provision of school breakfast has increased significantly in the UK. However, there is an absence of knowledge regarding senior stakeholder views on the processes and potential outcomes on different groups, within the communities served by school breakfast programs. The purpose of this study was to examine the views and experiences of senior level stakeholders and thereby provide an original qualitative contribution to the research. A sample of senior level stakeholders were recruited, including senior officers, directors and elected members, from within a Local Authority (LA involved in the leadership, implementation and delivery of a council-wide universal free school breakfast (USFB program, and from the senior staff body of mainstream primary and special schools, participating in the program. A grounded theory analysis of the data collected identified issues encountered in the implementation and delivery, and views on the funding and future of a USFB program, in addition to perceived outcomes of children, parents, families, schools and the wider community. The results refer to both positive and negative issues and implications associated with the program, according to the perspectives of senior level stakeholders. Perceived positive outcomes included benefits to children, families, schools and the community. For instance, alleviating hunger, improving health outcomes, and conferring financial benefits, with the potential to cumulate in overall improvements in educational, social and behavioral outcomes. Reported negative implications included the absence of an effective communication strategy in implementing the USFB program; in addition to concerns about the impacts of ‘double-breakfasting’ on obesity levels among children, particularly in less deprived communities. Findings were validated using theoretical sampling and saturation, triangulation methods, member checks, and inter-rater reliability measures. In

    The health benefits of school food have been widely promoted in recent years while the social opportunities that surround eating occasions at school have received little attention. Breakfast clubs (BCs), which take place at the start of the school day, offer a unique opportunity for children to consume a breakfast meal on their school premises in the company of their peers. Alternatively, after-school clubs (ASCs), which take place on school premises at the end of the school day, whilst also providing children with social opportunities tend to focus on sports engagement and skill development. The aim of the current paper is to investigate whether attendance at BCs and ASCs has an impact on children's friendship quality and experiences of peer victimization. BC attendees, ASC attendees, and non-attendees completed the Friendship Qualities Scale and the Multidimensional Peer Victimization Scale (MPVS) at two time points. Time-1 data were collected 2 months after the introduction of school clubs. Time-2 data were then collected on the same measures again 6 months later. Results of the analyses of Time-1 data showed no significant differences between groups on any of the measures at Time-1. However, at Time-2, BC attendees showed improved levels of friendship quality compared to the other two groups. Moreover, analysis of the MPVS data at Time-2 showed that children who attended BC or ASC experienced a decline in victimization across time. The current findings suggest that BC attendance facilitates the quality of children's relationships with their best friend over time. Additionally, attendance at a breakfast or ASC was associated with a reduction in victimization over time. The results have implications for utilization of breakfast and ASCs to aid children's social relationships in school over time.

    Data from the 2002, 2006 and 2010 Scottish Health Behaviour in School-aged Children (HBSC) surveys were analysed using logistic multilevel regression for outcome variable irregular breakfast consumption (IBC). IBC prevalence in Scotland was higher among young people from reconstituted and single parent families, and particularly single father families. Family characteristics, found previously to be associated with breakfast consumption, such as number of siblings, perceived parenting, parental involvement and family affluence, differed by family structure. Family structure inequalities in IBC existed, also after adjustment for year and child's sex, age, grade and ethnicity. Across all family structures, IBC was more prevalent at the older age groups, among those who had difficult communication with their parents, and where household routines were infrequent. Greater number of siblings and lower family affluence were associated with higher odds of IBC in single mother and both parent families, while having a second home was associated with higher odds in reconstituted households. Fair parenting and being close to at least one parent was associated with reduced odds of IBC in single mother households, while being close to all parents was in single father households. In single mother homes, having a working mother was also positively associated with IBC. Family structure differences should be considered when addressing irregular breakfast consumption in adolescence. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The impact of breakfasts of different glycaemic loads on the performance of nineteen children, aged six to seven years, was explored. Over a four week period, children attended a school breakfast club each day and ate one of three meals. Each meal offered a similar amount of energy but differed in their glycaemic load. When working individually, the behaviour of a child was rated in the classroom every ten seconds for 30 min to produce a measure of time spent on task. Memory was assessed by asking for the recall of a series of objects. The ability to sustain attention was measured by asking for a response after various delays. The incidence of negative behaviour was recorded when playing a video game that was too difficult to allow success. Two to three hours after a low glycaemic load breakfast had been consumed, performance on the tests of memory and the ability to sustain attention were better, fewer signs of frustration were displayed and initially more time was spent on task when working individually in class. The importance of the results was discussed in the context of the wide range of factors that influence behaviour in school.

    Full Text Available The objective of this work was to develop an extruded breakfast product containing broken rice and split old beans and to verify the influence of the extrusion process on their physicochemical, technological, and sensory characteristic. The final product had a protein content of 9.9 g.100 g-1, and therefore it can be considered a good source of proteins for children and teenagers. The dietary fiber content of the final edible product was 3.71 g.100 g-1. Therefore, the breakfast meal may be considered as a source of dietary fiber according to Brazilian law . As for the technological properties, the extruded product presented an expansion index of 8.89 and apparent density of 0.25 g.cm-3. With regard to the sensory analysis, the acceptance average was ranked between 6.8 and 7.7, corresponding to the categories "liked slightly" and "liked very much". With regard to purchase intention, 79% of the panelists said they would certainly or possibly purchase the product. Broken rice and split old beans are interesting alternatives for the elaboration of extruded breakfast products presenting good nutritional, technological, and sensory qualities.

    Food volume could influence both the portions that people take and the amount that they eat, but these effects have had little investigation. The influence of food volume was tested by systematically reducing the flake size of a breakfast cereal so that the cereal was more compact and the same weight filled a smaller volume. In a crossover design, 41 adults ate cereal for breakfast once a week for 4 weeks during 2011 and 2012. The cereal was either standard wheat flakes or the same cereal crushed to reduce the volume to 80%, 60%, or 40% of the standard. A constant weight of cereal was provided in an opaque container and participants poured the amount they wanted into a bowl, added fat-free milk and noncalorie sweetener as desired, and consumed as much as they wanted. Results from a mixed linear model showed that as flake size was reduced, subjects poured a smaller volume of cereal, but still took a greater amount by weight and energy content (both P values breakfast energy intake increased from a mean±standard error of the mean of 286±18 kcal to 358±19 kcal, an increase of a mean±standard error of the mean 34%±7% (Pportion served, which in turn affects energy intake.

    This project aims primarily to give a basis for the joint R and D program for the Swedish electric utility industry, in the form of pictures of the future up to 2020. The work was performed during four seminars in a group of managers and R and D planners. The four scenarios differ mainly in the assumptions of high or low economic growth and on market or political rule. Assumptions on essential uncertainties about the future have been combined in a consistent manner, e.g. on the structure of the utility industry, the role of nuclear power, the importance of the greenhouse gas issue, the influence of new technology developments and on changes of values in society. Certain other development appear in all scenarios, e.g. the impact of information technology throughout society, the internationalization of business in general and industrial production in particular, considerations for the environment and care for natural resources. The four scenarios are: 'Technology on the throne' (market rule/high growth); 'Intense competition' (market rule/low growth); 'Monopoly takes over' (political rule/high growth); and 'Green local society' (political rule/low growth). Some of the important factors pointed out by the study are: Increased customer mobility between regions and countries; The impact of information technology; Societal value changes; Sustainable development as an important driving force; Structure of the utility industry. Diversifying into new services. New players; Access to knowledge and competence; Ways for handling the greenhouse gas problem; Preparedness for nuclear power phase-out. 12 figs, 6 tabs

    Research has shown that adolescents who frequently share evening meals with their families experience more positive health outcomes, including diets of higher nutritional quality. However, little is known about families eating together at breakfast. This study examined sociodemographic differences in family meal frequencies in a population-based adolescent sample. In addition, this study examined associations of family breakfast meal frequency with dietary quality and weight status. Cross-sectional data from EAT 2010 (Eating and Activity in Teens) included anthropometric assessments and classroom-administered surveys completed in 2009-2010. Participants included 2,793 middle and high school students (53.2% girls, mean age=14.4 years) from Minneapolis/St Paul, MN, public schools. Usual dietary intake was self-reported on a food frequency questionnaire. Height and weight were measured. Regression models adjusted for sociodemographic characteristics, family dinner frequency, family functioning, and family cohesion were used to examine associations of family breakfast frequency with dietary quality and weight status. On average, adolescents reported having family breakfast meals 1.5 times (standard deviation=2.1) and family dinner meals 4.1 times (standard deviation=2.6) in the past week. There were racial/ethnic differences in family breakfast frequency, with the highest frequencies reported by adolescents of black, Hispanic, Native American, and mixed race/ethnicity. Family breakfast frequency was also positively associated with male sex, younger age, and living in a two-parent household. Family breakfast frequency was associated with several markers of better diet quality (such as higher intake of fruit, whole grains, and fiber) and lower risk for overweight/obesity. For example, adolescents who reported seven family breakfasts in the past week consumed an average of 0.37 additional daily fruit servings compared with adolescents who never had a family breakfast meal

    The ILC Technical Design Report documents the design for the construction of a linear collider which can be operated at energies up to 500 GeV. This report summarizes the outcome of a study of possible running scenarios, including a realistic estimate of the real time accumulation of integrated luminosity based on ramp-up and upgrade processes. The evolution of the physics outcomes is emphasized, including running initially at 500 GeV, then at 350 GeV and 250 GeV. The running scenarios have been chosen to optimize the Higgs precision measurements and top physics while searching for evidence for signals beyond the standard model, including dark matter. In addition to the certain precision physics on the Higgs and top that is the main focus of this study, there are scientific motivations that indicate the possibility for discoveries of new particles in the upcoming operations of the LHC or the early operation of the ILC. Follow-up studies of such discoveries could alter the plan for the centre-of-mass collision energy of the ILC and expand the scientific impact of the ILC physics program. It is envisioned that a decision on a possible energy upgrade would be taken near the end of the twenty year period considered in this report.

  8. Erosion scenarios for Wellenberg

    1993-09-01

    The proposed Wellenberg site for a radioactive waste repository is located between Altzellen in the Engelberger valley and the Oberrickenbach valley, in a thick Valanginian marl series. The marl is generally overlaid with unconsolidated rocks but reaches to the surface in some places. In contrast to the situation in the Oberbauenstock region this marl complex is not protected by an overlying erosion resistant series and exhibits a marked relief. The question therefore arises with respect to the Wellenberg site, to what extent will the marl (i.e. the repository host rock formation) be removed by erosion processes during the 100,000 years interval under consideration and what overburden will remain at the end of this period. This report presents the results of an investigation of the longterm behaviour of the proposed site in respect of those processes of erosion and deposition which can lead to changes in the terrain surface and its location relative to the repository. A wide range of possible scenarios encompassing different developments of climatic conditions during the 100,000 year period of interest, was investigated. In addition to the continuation of the present climate and the occurrence of a new ice age on the scale of the Wuerm glaciation the consequences of altered climatic conditions on erosion removal of the repository overburden were considered. Within the 100,000 year period of interest none of the scenarios considered leads to the exposure of the repository. (author) figs., tabs, refs

    To examine the association between skipping breakfast, daily energy, macronutrients and food intakes, and BMI in pre-school children. A cross-sectional study using information on children's food consumption and measured height and weight. Energy and macronutrient intakes of the children were derived from parent/day-care attendant's responses to 24 h recall interviews and eating behaviour questionnaires. Data obtained from a representative sample (n 2,103) of children born in Quebec (Canada) in 1998. One thousand five hundred and forty-nine children, with a mean age of 49 (sd 3.12) months. Ten per cent of children ate breakfast on fewer than 7 days per week. This behaviour was associated with a lower diet quality and concentrated energy intakes through higher protein intakes at lunch and the consumption of snacks higher in energy and carbohydrate in the afternoon and evening; yet total daily energy intakes were not significantly different from those of pre-school children who ate breakfast every day. Breakfast skippers' mean BMI increased as intake of energy, carbohydrates or servings of grain products increased; however, this was not the case for breakfast eaters. When Cole's cut-off for overweight/obesity was used, overweight/obesity in breakfast skippers was related to the dinner-time consumption of approximately 3,000 kJ (700 kcal) or more for energy intake, approximately 100 g or more of carbohydrates, or approximately 3 servings or more of grain products. Eating breakfast every day is associated with having a healthy body weight, likely due to a more even distribution of energy intake across meals throughout the day.

    To evaluate whether consumption of breakfast cereals is associated with BMI in a sample of Greek adolescents. A cross-sectional health and nutrition survey. During 2004-5, 2008 schoolchildren aged 12-17 years were selected from twelve schools located in Vyronas region (Athens metropolitan area). Height and weight were measured and BMI was calculated. A semiquantitative FFQ was applied and multiple logistic regression analysis was used. Overall, 4.7% of boys and 1.7% of girls were obese, whereas 19.4% of boys and 13.2% of girls were overweight. Only 20.7% of boys and 15.5% of girls reported that they consume cereals as a first choice for breakfast. Consumption of breakfast cereals was associated with lower BMI in boys (P=0.08) and girls(P=0.019), irrespective of age and physical activity status. More prominent results were observed for daily cereal consumption or for more than two daily servings of cereals consumed for breakfast. Consumption of pre-sweetened breakfast cereals was associated with lower BMI compared with non-pre-sweetened or no intake of cereals, in both genders (PConsumption of breakfast cereals was associated with 33% (95% CI 14%, 48%) lower likelihood of overweight/obesity, irrespective of age, sex and physical activity status. Consumption of breakfast cereals was associated with lower BMI levels and a lower likelihood of overweight/obesity in both genders; thus a solid basis for public health professionals could be built when issuing advice on weight management.

    Full Text Available Background and Objectives: Despite associating regular breakfast consumption habits with a range of health benefits, the rate of skipping the meal is high. The present study was conducted to determine the factors associated with breakfast consumption among female students of Hamadan University of Medical Sciences based on the Social Cognitive Theory (SCT. Materials and Methods: The present cross-sectional study was carried out on 423 female students in different faculties of Hamadan University of Medical Sciences. Participants were selected through multistage random sampling. The frequency of breakfast consumption and SCT variables, including knowledge, hope, outcome expectancies, observational learning, social support and self-efficacy, was measured using a self-administered questionnaire. Data were analyzed in SPSS-16 using the chi-square test, the correlation test and the linear regression analysis. Results: 24% of the students stated that they always ate breakfast. 10% of the students skipped breakfast. On average, the students ate breakfast 4.2 times a week. Self-efficacy (p<0.001 and social support (p<0.001 were good predictors of breakfast consumption in the students. These two variables were able to predict 64% of the variance in breakfast habits. Conclusion: The results show that self-efficacy and social support should be targeted in the design of interventions intending to increase breakfast consumption among female university students.

    To evaluate the relationship between eating pattern (regular breakfast, lunch and dinner) and dialysis sessions, laboratory and sociodemographic characteristics in hemodialysis (HD) patients. In this cross-sectional study eating patterns, sociodemographic, laboratory and clinical parameters, depressive symptoms, quality of life, cognitive function and appetite status were assessed. Eighty-two HD patients on morning session and 60 patients on midday HD session schedules were included. Ten patients had only breakfast, 17 patients had only lunch, 26 patients had only dinner, 5 patients had breakfast and lunch but not dinner, 28 patients had breakfast and dinner but not lunch, 29 patients had lunch and dinner but not breakfast, and 19 patients had neither breakfast, nor lunch, nor dinner. In the whole group, only 8 patients reported that they had regularly eaten breakfast, lunch or dinner in all days of the week. Midday HD session, better appetite, and higher income were independently associated with having breakfast. Morning HD session, better appetite score, and higher income were independently associated with having lunch. Morning session versus midday session, nPNA, presence of hypertension, and the Mental Component Summary Score of SF-36 were independently associated with having dinner. The majority of HD patients eat one or two meals per day. Having breakfast (or lunch) is associated with midday dialysis session (or morning dialysis session, respectively), better appetite, and satisfactory income. Eating dinner was associated with morning dialysis session, hypertension, higher protein intake and higher SF-36 mental component summary score.

    Gastrin, secretin and cholecystokinin were determined by a radioimmunoassay in healthy persons (19) and in patients with peptic ulcer (13) on an empty stomach and after test breakfasts with different nutrients. In the healthy persons the blood concentration of regulatory peptides was lower than in the patients. Breakfasts increased the concentrations of gastrin, secretin and cholecystokinin in the patients much more than in the controls. Some differences in changes of the blood concentration of peptides were noted with regard to a type of test breakfast. However differentiated reactions of the endocrine apparatus of the gastroduodenal complex in response to the breakfasts were not a reliable functional and diagnostic criterion

    Understanding the development of the biofuels industry in the United States is important to policymakers and industry. The Biomass Scenario Model (BSM) is a system dynamics model of the biomass-to-biofuels system that can be used to explore policy effects on biofuels development. Because of the complexity of the model, as well as the wide range of possible future conditions that affect biofuels industry development, we have not developed a single reference case but instead developed a set of specific scenarios that provide various contexts for our analyses. The purpose of this report is to describe the scenarios that comprise the BSM scenario library. At present, we have the following policy-focused scenarios in our library: minimal policies, ethanol-focused policies, equal access to policies, output-focused policies, technological diversity focused, and the point-of-production- focused. This report describes each scenario, its policy settings, and general insights gained through use of the scenarios in analytic studies.

    The causal nature of associations between breakfast and health remain unclear in obese individuals. We sought to conduct a randomized controlled trial to examine causal links between breakfast habits and components of energy balance in free-living obese humans. The Bath Breakfast Project is a randomized controlled trial with repeated measures at baseline and follow-up among a cohort in South West England aged 21-60 y with dual-energy X-ray absorptiometry-derived fat mass indexes of ≥13 kg/m(2) for women (n = 15) and ≥9 kg/m(2) for men (n = 8). Components of energy balance (resting metabolic rate, physical activity thermogenesis, diet-induced thermogenesis, and energy intake) were measured under free-living conditions with random allocation to daily breakfast (≥700 kcal before 1100) or extended fasting (0 kcal until 1200) for 6 wk, with baseline and follow-up measures of health markers (e.g., hematology/adipose biopsies). Breakfast resulted in greater physical activity thermogenesis during the morning than when fasting during that period (difference: 188 kcal/d; 95% CI: 40, 335) but without any consistent effect on 24-h physical activity thermogenesis (difference: 272 kcal/d; 95% CI: -254, 798). Energy intake was not significantly greater with breakfast than fasting (difference: 338 kcal/d; 95% CI: -313, 988). Body mass increased across both groups over time but with no treatment effects on body composition or any change in resting metabolic rate (stable within 8 kcal/d). Metabolic/cardiovascular health also did not respond to treatments, except for a reduced insulinemic response to an oral-glucose-tolerance test over time with daily breakfast relative to an increase with daily fasting (P = 0.05). In obese adults, daily breakfast leads to greater physical activity during the morning, whereas morning fasting results in partial dietary compensation (i.e., greater energy intake) later in the day. There were no differences between groups in weight change and most

    It remains unknown whether sustained daily feeding-fasting patterns modify the acute response to specific feedings on a given day. We conducted a randomized controlled trial to establish if daily breakfast consumption or fasting until noon modifies the acute metabolic and appetitive responses to a fixed breakfast and ad libitum lunch. With the use of a parallel group design, we randomly assigned 31 healthy, lean men and women (22-56 y) to 6 wk of either consuming ≥700 kcal of self-selected items before 1100 or fasting (0 kcal) until 1200 daily. Following 48 h of diet and physical activity standardization, we examined metabolic and appetite responses to a standardized breakfast and ad libitum lunch before and after the intervention. Data were analyzed using 3- and 2-way ANCOVA. Systemic concentrations of energy balance regulatory hormones total and acylated ghrelin, leptin, and peptide tyrosine-tyrosine) responded similarly to breakfast and lunch before and after 6 wk of either morning fasting or regular breakfast, with the exception of a tendency for increased glucagon-like peptide-1 concentrations from baseline to follow-up in the Breakfast Group compared with a decrease over that period in the Fasting Group [P = 0.06, partial eta squared value (ƞ2) = 0.16]. Subjective appetite sensations also did not differ over the course of the day, and ad libitum energy intake at lunch was not systematically affected by either intervention, decreasing by 27 kcal (95% CI: -203, 149 kcal) with fasting and by 77 kcal (95% CI: -210, 56 kcal) with breakfast. Similarly, glycemic, insulinemic, lipemic, and thermogenic responses to breakfast and lunch were very stable at baseline and follow-up and, thus, did not differ between treatment groups. Our results indicate that a sustained period of either extended morning fasting or eating a daily breakfast has minimal effect upon acute metabolic and appetite responses in lean adults.

    Across the UK, 1.3 million children access free school meals for around 38 weeks of the year. However, during school holidays, many families face considerable difficulties in providing a consistent and nutritious supply of food for their children, particularly during the extended summer break. In an effort to address this issue, a number of community-based breakfast clubs were set-up across the North West of England and in Northern Ireland where people could access a free breakfast meal during the summer holidays. Qualitative interviews were carried out with 17 children, 18 adult attendees, and 15 breakfast club staff to determine the uses and impacts associated with holiday breakfast club participation and to investigate potential areas for future development of holiday food provision. Findings highlighted a need for holiday food provision and revealed a multitude of nutritional, social, and financial benefits for those who accessed holiday breakfast clubs.

    Scenario planning may assist us in harnessing the benefits of nanotechnology and managing the associated risks for the good of the society. Scenario planning is a way to describe the present state of the world and develop several hypotheses about the future of the world, thereby enabling discussions about how the world ought to be. Scenario planning thus is not only a tool for learning and foresight, but also for leadership. Informed decision making by experts and political leaders becomes possible, while simultaneously allaying the public's perception of the risks of new and emerging technologies such as nanotechnology. Two scenarios of the societal impact of nanotechnology are the mixed-signals scenario and the confluence scenario. Technoscientists have major roles to play in both scenarios.

  6. Storytelling Permutations in the Performance of Life Narrative Betty Roland's Caviar for Breakfast.

    Directory of Open Access Journals (Sweden)

    Maureen Clark

    2013-11-01

    Full Text Available Throughout her life, Australian storyteller and playwright Betty Roland (1903-1996 was haunted by the lure of travel. Roland's extensive body of work reflects experiences in Joseph Stalin's Soviet Union in the 1930s, the UK in the 1950s and Greece in the 1960s and charts the evolution of a personal and political philosophy marked by world-wide social upheaval. Caviar for Breakfast (1979 revised 1989, the second volume of Roland's autobiographical trilogy, is the subject of this paper. When taken together, the three books provide a fascinating insight into the values and ideas of the mushrooming modern cultures in which Roland travelled, worked and lived. Caviar for Breakfast retraces Roland's adventures in Joseph Stalin's Soviet Union where she spent fifteen months during 1933-34 with her then lover, Guido Baracchi, a wealthy Marxist scholar. The narrative takes its life from the contents of a diary maintained by Roland during that time and her introductory remarks convey the notion that, what follows, is not a literary enterprise of the imagination. The author insists that Caviar for Breakfast is a first-hand account of past realities and not only does her diary hold the ordering of events together, but is the purveyor of truth. The truth status of the diary as a mode of representation is widely accepted in Western culture. This paper argues, however, that it is impossible for any transcription of a life to enjoy a one-to-one ratio with 'what actually happened' as it is for a ghost to re-enter a world which fully resembles the one it left. It is well within the capacity of any imaginative storyteller to construct a counterfeit, or simulated, sense of reality whether or not s/he works with the diary mode of representation.

    The sweetpotato [Ipomoea batatas (L.) Lam], an important industry in the United States, has been selected as a candidate crop to be grown on future long-duration space missions by NASA. Raw sweetpotato roots were processed into flour, which was used to formulate ready-to-eat breakfast cereal (RTEBC). Twelve trained panelists evaluated the sensory attributes of the extruded RTEBC using descriptive analysis. The samples were significantly different (Psensory attributes, which could be used to differentiate the appearance, texture, and flavor of sweetpotato RTEBC, were described. The data could be used to optimize the RTEBC and for designing studies to test its consumer acceptance.

    Nursing facilities often provide enhanced or fortified foods as part of a "food-first" approach to increasing nutrient intakes in residents with inadequate intakes or who are experiencing weight loss. The study objective was to determine whether energy and protein enhancement of a small number of menu items would result in increased three-meal (breakfast, lunch, and supper) calorie and protein intakes in long-term care residents. A randomized cross-over design was used to compare investigator-weighed food intakes under three menu conditions: control (no meals enhanced); lunch only enhanced; and both breakfast and lunch enhanced. Two breakfast foods (juice and hot cereal) and two lunch foods (soup and potato side dish) were chosen for enhancement. Participants were 33 nursing home residents from a facility in South Florida (average age=87.3 years). Repeated-measures analysis of variance was used to test the effects of the within-subjects factor (control, lunch enhanced, breakfast and lunch enhanced conditions), the between-subjects factor (smaller vs bigger eater), and the interaction on intakes (gram, kilocalories, and protein). Results revealed that bigger eaters consumed considerably more calories when breakfast foods, but not lunch foods, were enhanced. Smaller eaters achieved an increase in energy intake when either breakfast or lunch was enhanced. Overall daily protein intakes were not substantially increased by food enhancement. These data suggest that for an enhanced food program to be most effective for smaller eaters, who are at greatest risk for undernutrition and weight loss, it should include several enhanced foods at more than one meal.

    To understand stakeholders' perspectives on food waste in a universal free School Breakfast Program implementing a Breakfast in the Classroom model. Semi-structured focus groups and interviews were conducted with school district stakeholders. Inductive methods were used to code resulting transcripts, from which themes were identified. The analysis provides a thematic analysis of stakeholders' perspectives on food waste in the School Breakfast Program. Ten elementary schools in a large urban school district implementing a universal free Breakfast in the Classroom model of the US national School Breakfast Program. Elementary-school students (n 85), parents (n 86), teachers (n 44), cafeteria managers (n 10) and school principals (n 10). Stakeholders perceived food waste as a problem and expressed concern regarding the amount of food wasted. Explanations reported for food waste included food-related (palatability and accessibility), child-related (taste preferences and satiation) and programme-related (duration, food service policies, and coordination) factors. Milk and fruit were perceived as foods particularly susceptible to waste. Several food waste mitigation strategies were identified by participants: saving food for later, actively encouraging children's consumption, assisting children with foods during mealtime, increasing staff support, serving smaller portion sizes, and composting and donating uneaten food. Stakeholders recognized food waste as a problem, reported myriad contributing factors, and have considered and employed multiple and diverse mitigation strategies. Changes to the menu and/or implementation logistics, as well as efforts to use leftover food productively, may be possible strategies of reducing waste and improving the School Breakfast Program's economic, environmental and nutritional impact.

    Full Text Available Evidence indicates that breakfast consumption is associated with a cluster of health-related behaviors, yet studies in mainland China are scarce. This study is conducted to describe the frequency of breakfast consumption among Chinese adolescents and examine its associations with other dietary, physical activity, sedentary, sleep, cigarette-smoking, and alcohol-drinking behaviors. Breakfast consumption and other health-related behaviors data was collected via a self-administered questionnaire in a cross-sectional study in Zhejiang Province, China. A total of 19,542 school-aged adolescents were recruited in this survey. The associations between breakfast consumption and other health-related behaviors were examined using logistic regression models. A significantly higher prevalence of daily breakfast consumption was found among students who were younger (p for trend <0.001, from urban schools (p < 0.001, and academic high schools (p < 0.001. More frequent vegetable and milk consumption, greater physical activity, and longer sleep duration were positively associated with daily breakfast consumption, while soft drinks and fast food consumption, computer use, cigarette-smoking and alcohol-drinking behaviors were inversely associated. The prevalence of irregular breakfast consumption was relatively high among Chinese adolescents in Zhejiang Province. Daily breakfast consumption was associated with a constellation of health-related behaviors.

    The past seven decades have seen remarkable shifts in the nutritional scenario in India. Even up to the 1950s severe forms of malnutrition such as kwashiorkar and pellagra were endemic. As nutritionists were finding home-grown and common-sense solutions for these widespread problems, the population was burgeoning and food was scarce. The threat of widespread household food insecurity and chronic undernutrition was very real. Then came the Green Revolution. Shortages of food grains disappeared within less than a decade and India became self-sufficient in food grain production. But more insidious problems arising from this revolution were looming, and cropping patterns giving low priority to coarse grains and pulses, and monocropping led to depletion of soil nutrients and 'Green Revolution fatigue'. With improved household food security and better access to health care, clinical manifestations of severe malnutrition virtually disappeared. But the decline in chronic undernutrition and "hidden hunger" from micronutrient deficiencies was slow. On the cusp of the new century, an added factor appeared on the nutritional scene in India. With steady urban migration, upward mobility out of poverty, and an increasingly sedentary lifestyle because of improvements in technology and transport, obesity rates began to increase, resulting in a dual burden. Measured in terms of its performance in meeting its Millennium Development Goals, India has fallen short. Despite its continuing high levels of poverty and illiteracy, India has a huge demographic potential in the form of a young population. This advantage must be leveraged by investing in nutrition education, household access to nutritious diets, sanitary environment and a health-promoting lifestyle. This requires co-operation from all the stakeholders, including governments, non government organizations, scientists and the people at large.

    Scenarios of global greenhouse gas emissions have played a key role in climate change analysis for over twenty years. Currently, several research communities are organizing to undertake a new round of scenario development in the lead-up to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). To help inform this process, we assess a number of past efforts to develop and learn from sets of global greenhouse gas emissions scenarios. We conclude that while emissions scenario exercises have likely had substantial benefits for participating modeling teams and produced insights from individual models, learning from the exercises taken as a whole has been more limited. Model comparison exercises have typically focused on the production of large numbers of scenarios while investing little in assessing the results or the production process, perhaps on the assumption that later assessment efforts could play this role. However, much of this assessment potential remains untapped. Efforts such as scenario-related chapters of IPCC reports have been most informative when they have gone to extra lengths to carry out more specific comparison exercises, but in general these assessments do not have the remit or resources to carry out the kind of detailed analysis of scenario results necessary for drawing the most useful conclusions. We recommend that scenario comparison exercises build-in time and resources for assessing scenario results in more detail at the time when they are produced, that these exercises focus on more specific questions to improve the prospects for learning, and that additional scenario assessments are carried out separately from production exercises. We also discuss the obstacles to better assessment that might exist, and how they might be overcome. Finally, we recommend that future work include much greater emphasis on understanding how scenarios are actually used, as a guide to improving scenario production.

    Three energy scenarios have been formulated for New Zealand. They concentrate on those aspects of society which have a direct bearing on energy, emphasizing three important issues: major shifts in society's values in relation to material wealth, pollution, and resources. The scenarios make assumptions that certain overall social conditions would prevail so that all decisions of government, the private sector, and individuals would be governed by the requirement to conform to the scenario theme in a way not possible under existing social and political conditions. The 3 scenarios are known as Continuation, Low New Zealand Pollution, and Limited Growth.

    1997-01-01

    In order to examine the effect of energy intake at breakfast on school performance the same morning, the parents of ten parallel school classes of 10-year-old school children at five different schools were persuaded to alter their child's breakfast regimen at home over a period of 4 successive days. A total of 195 families were provided with standard breakfasts with either low or high energy content. Uneaten food was returned and weighed. Individual children were randomly assigned to breakfast alternative on any given day. The teachers who carried out the performance assessments at school were blind to treatment condition. Voluntary physical endurance and the performance of a creativity test were significantly better after a breakfast from which children derived over 20% of their recommended daily energy intake than after a breakfast from which they obtained less than 10% of recommended values. The error rate in an addition task was negatively correlated and the rate of working in a number checking task was positively correlated with individual energy intake from the low-energy breakfast. Significantly fewer children reported feeling bad and self-estimates of hunger sensation were lower during the morning at school after the high energy breakfast. Estimates of energy intake at breakfast based on 24-h dietary recall interviews with the children carried out by telephone at their homes showed good correlation with estimates based on returned food (r = 0.89). Energy intake at breakfast as estimated from returned food had no significant effect on energy intake at school lunch as estimated by dietary recall.

    Suboptimal health status (SHS) is the intermediate health state between health and disease, refers to medically undiagnosed or functional somatic syndromes, and has been a major global public health challenge. However, both the etiology and mechanisms associated with SHS are still unclear. Breakfast eating behavior is a dietary pattern marker and previous studies have presented evidence of associations between failure to consume breakfast and increased diseases. Accordingly, in view of the significance of breakfast eating behaviors with respect to health status, the associations between breakfast eating habits and healthy lifestyle, SHS require further elucidation. A cross-sectional survey was conducted within a clustered sample of 24,159 individuals aged 12-80 years in 2012-13 within the population of Southern China. Breakfast eating habits were categorically defined by consumption frequency ('scarcely, sometimes or always'). Health-promoting lifestyle was assessed via the health-promoting lifestyle profile (HPLP-II). SHS was evaluated using the medical examination report and Sub-health Measurement Scale V1.0 (SHMS V1.0). Of the 24,159 participants, the prevalence rates for the 'health' , 'SHS' , and 'disease' were 18.8%, 46.0%, and 35.2%, respectively. Overall, 19.6% of participants reported 'scarce' breakfast eating habits, with frequent breakfast eaters scoring higher on both HPLP-II and SHMS V1.0. After demographic adjustment, regression analyses revealed a significant association between breakfast eating habits and healthy lifestyle (p eating habits are significantly associated with a healthy lifestyle, and appear to be a useful predictor of a healthy lifestyle. Irregular breakfast eating habits are related to an increased risk of SHS; increased breakfast eating frequency may contribute to lowering the prevalence of SHS in Southern China.

Methods A total of 264 participants aged 25–45 years will be recruited from Shenyang and Chongqing. Self-administered questionnaires will be used to collect information on age, gender, marital status, education level, occupation, smoking habits, drinking habits, and breakfast behaviours. The participants will be randomly assigned to 3 equal-sized groups (Groups A, B, and C and will be provided with a nutrition-adequate breakfast, a nutrition-inadequate breakfast, or no breakfast, respectively. Each participant will receive the breakfast treatment on the basis of assignment to one of three sequences (ABC/BCA/CAB. Each participant will complete a battery of cognitive tests assessing short-term memory, attention, and working memory 120 minutes after breakfast. Mood will be measured through a self-administered questionnaire assessing the dimensions of positive and negative frames of mind. Additionally, fasting blood glucose and postprandial 2-hour blood glucose levels will be tested with a blood-glucose meter (Roche ACCU-CHEK®-Performa. All the participants will take all the tests in three successive weeks, and the order of presentation will be counter-balanced across groups. Discussion The present study will be the first investigation of the effect of breakfast food type and quality on cognitive function amongst white-collar workers in China. We predict that a nutrition-adequate breakfast, compared with a nutrition-inadequate breakfast and no breakfast, will significantly improve short-term cognitive function. The results of this study should provide scientific evidence of the effect of

    The Sunrise balloon-borne solar observatory, consisting of a 1 m aperture telescope that provides a stabilized image to a UV filter imager and an imaging vector polarimeter, carried out its second science flight in 2013 June. It provided observations of parts of active regions at high spatial resolution, including the first high-resolution images in the Mg ii k line. The obtained data are of very high quality, with the best UV images reaching the diffraction limit of the telescope at 3000 Å after Multi-Frame Blind Deconvolution reconstruction accounting for phase-diversity information. Here a brief update is given of the instruments and the data reduction techniques, which includes an inversion of the polarimetric data. Mainly those aspects that evolved compared with the first flight are described. A tabular overview of the observations is given. In addition, an example time series of a part of the emerging active region NOAA AR 11768 observed relatively close to disk center is described and discussed in some detail. The observations cover the pores in the trailing polarity of the active region, as well as the polarity inversion line where flux emergence was ongoing and a small flare-like brightening occurred in the course of the time series. The pores are found to contain magnetic field strengths ranging up to 2500 G, and while large pores are clearly darker and cooler than the quiet Sun in all layers of the photosphere, the temperature and brightness of small pores approach or even exceed those of the quiet Sun in the upper photosphere.

    Although previous research has associated the glycaemic load (GL) of a meal with cognitive functioning, typically the macro-nutrient composition of the meals has differed, raising a question as to whether the response was to GL or to the energy, nutrients or particular foods consumed. Therefore, the present study contrasted two breakfasts that offered identical levels of energy and macro-nutrients, although they differed in GL. Using a repeated-measures, double-blind design, 75 children aged 5-11 years, from socially deprived backgrounds, attended a school breakfast club and on two occasions, at least a week apart, they consumed a meal sweetened with either isomaltulose (Palatinose™) (GL 31.6) or glucose (GL 59.8). Immediate and delayed verbal memory, spatial memory, sustained attention, reaction times, speed of information processing and mood were assessed 1 and 3 h after eating. The nature of the meals did not influence any measure of cognition or mood after an hour; however, after 3 h, children's memory and mood improved after the lower-GL breakfast. If children had eaten the lower-GL meal on the second day of testing, they were able to process information faster and had better spatial memory later in the morning. Towards the end of a morning in school, having consumed a lower-GL breakfast resulted in better mood and aspects of cognitive functioning.

    Full Text Available Meals with low glycemic index (GI may suppress short-term appetite and reduce subsequent food intake compared with high-GI meals. However, no meta-analysis has been conducted to synthesize the evidence. This meta-analytic study was conducted to assess the effect of high- and low-GI breakfast on subsequent short-term food intake. Trials were identified through MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled trials, and manual searches of bibliographies until May 2015. Randomized controlled and cross-over trials comparing the effect of low- with high-GI breakfast on subsequent energy intake among healthy people were included. Nine studies consisting of 11 trials met the inclusion criteria. Only one trial was classified with high methodological quality. A total of 183 participants were involved in the trials. The meta-analytic results revealed no difference in breakfast GI (high-GI vs. low-GI on subsequent short-term energy intake. In conclusion, it seems that breakfast GI has no effect on short-term energy intake among healthy people. However, high quality studies are still warranted to provide more concrete evidence.

    Merely contemplating one's death improves retention for entirely unrelated material learned subsequently. This "dying to remember" effect seems conceptually related to the survival processing effect, whereby processing items for their relevance to being stranded in the grasslands leads to recall superior to that of other deep processing control conditions. The present experiments directly compared survival processing scenarios with "death processing" scenarios. Results showed that when the survival and dying scenarios are closely matched on key dimensions, and possible congruency effects are controlled, the dying and survival scenarios produced equivalently high recall levels. We conclude that the available evidence (cf. Bell, Roer, & Buchner, 2013; Klein, 2012), while not definitive, is consistent with the possibility of overlapping mechanisms.

    Full Text Available Abstract Background Skipping breakfast was found to be associated with abdominal obesity in primary school children. The aim of this research was to examine factors associated with skipping breakfast in primary school children in order to develop targeted preventive measures. Methods Baseline data assessment (2010 of a cluster-randomized controlled trial for the evaluation of a school-based health promotion program in primary school children in the state of Baden-Württemberg, Germany. Anthropometric measures of 1,943 primary school children aged 7.1 ± 0.6 years (51.2% boys were conducted according to ISAK-standards (International Standard for Anthropometric Assessment by trained staff. Further information on the health and living conditions of the children and their parents were assessed in parental questionnaires. Generalized linear mixed regression analysis was calculated to define correlates for skipping breakfast in terms of odds ratios (OR and 95% confidence intervals (CI. Results According to the final regression models, significant correlates of skipping breakfast can be divided into modifiable behavioral components (high consumption of soft drinks (OR 2.49, 95% CI 1.81; 3.43, screen media (OR 2.48, 95% CI 1.77; 3.46 and high levels of physical activity (OR 0.64, 95% CI 0.44; 0.93 on the one hand, and more or less static socio-economic factors (migration background (OR 2.81, 95% CI 2.02; 3.91, single parenting (OR 2.13, 95% CI 1.34; 3.40, and high family education level (OR 0.42, 95% CI 0.28; 0.64 on the other hand, and finally individual factors (female gender (OR 1.43, 95% CI 1.03; 1.99 and having a percentage of body fat at or above the 95th percentile (OR 1.47, 95% CI 1.00; 2.17. Conclusion Targeted prevention should aim at health-related behaviors accompanying the habit of skipping breakfast.

    There are very few studies on the frequency of breakfast and snack consumption and its relation to fruit and vegetable intake. This study aims to fill that gap by exploring the relation between irregular breakfast habits and snack consumption and fruit and vegetable intake in Tuscan adolescents. Separate analyses were conducted with an emphasis on the potentially modifying factors of sex and age. Data was obtained from the 2010 Tuscan sample of the Health Behaviour in School-aged Children (HBSC) study. The HBSC study is a cross-sectional survey of 11-, 13- and 15-year-old students (n = 3291), selected from a random sample of schools. Multivariate logistic regression was used for analyzing the food-frequency questionnaire. A significant relation was found between low fruit and vegetable intake and irregular breakfast habits. Similarly, low fruit intake was associated with irregular snack consumption, whereas vegetable intake did not prove to be directly related to irregular snack consumption. Different patterns emerged when gender and age were considered as modifying factors in the analyses. A statistically significant relation emerged only among female students for irregular breakfast habits and fruit and vegetable intake. Generally, older female participants with irregular breakfast habits demonstrated a higher risk of low fruit and vegetable intake. Age pattern varied between genders, and between fruit and vegetable consumption. Results suggest that for those adolescents who have an irregular consumption of breakfast and snacks, fruit intake occurs with a lower frequency. Lower vegetable consumption was associated with irregular breakfast consumption. Gender and age were shown to be moderators and this indicated the importance of analyzing fruit and vegetable intake and meal types separately. This study also confirmed that health-promotion campaigns that aim to promote regular meal consumption and consumption of fruits and vegetables need to take into account

Results from an initial field pilot study showed that higher energy intake at breakfast was associated with lower fatigue and higher overall mood and alertness post-exercise (all p < 0.05. In a follow-up, randomised, controlled trial, 24 active women completed three trials in a balanced, cross-over design. At 0815 h participants completed baseline cognitive tasks, mood and appetite visual analogue scales (VAS and were administered a cereal breakfast (providing 118 or 236 kcal or no breakfast. After 45 min, they completed a 30 min run at 65% heart rate reserve (HRR. Parameters were re-assessed immediately after exercise, then hourly until lunch (~1240 h, immediately post-lunch and at 1500 and 1900 h via a mobile phone. Breakfast enhanced feelings of relaxation before lunch (p < 0.05, d > 0.40, though breakfast was detrimental for working memory mid-afternoon (p = 0.019, d = 0.37 and mental fatigue and tension later in the day (all p < 0.05, d > 0.038. Breakfast was also beneficial for appetite control before lunch irrespective of size (all p < 0.05, d > 0.43. These data provide information on pre-exercise nutritional practices for active females and suggest that a small breakfast eaten prior to exercise can benefit post-exercise mood and subjective appetite ratings.

    Background : The association between different types of breakfast meals and nutrient intakes has been studied to a lesser extent. Objective : This study compared nutrient intakes at breakfast and throughout the day between Malaysian children who consumed ready-to-eat cereals (RTEC) and those who did not. Methods : Anthropometric and dietary data for 1955 children aged 6-12 years from the MyBreakfast study were used in the analysis. Results : Overall, 18% of the children consumed RTEC at breakfast on at least one of the recall days. RTEC consumption was associated with younger age, urban areas, higher income and education level of parents. Among consumers, RTEC contributed 10% and 15% to daily intakes of calcium and iron respectively and ≥20% to daily intakes of vitamin C, thiamin, riboflavin and niacin. RTEC consumers had significantly higher mean intakes of vitamin C, thiamin, riboflavin, niacin, calcium, iron and sugar but lower intakes of fat and sodium than non-RTEC consumers at breakfast and for the total day. Conclusion : Consumption of fortified RTEC at breakfast was associated with lower fat and sodium intakes and higher intakes of several micronutrients both at breakfast and for the total day. However, total sugar intakes appeared to be higher.

    Few studies have investigated the association between adolescents' socio-economic status (SES) and health behaviours in developing countries. Socio-economic differences in breakfast eating, fruit and vegetable consumption and physical activity were investigated among Ghanaian adolescents. A school-based survey of 12-18-year-olds (n 1195, response rate 89·7 %) was conducted in 2008. Logistic regression analyses were applied to study the associations between breakfast eating, fruit and vegetable consumption and physical activity, and SES. Southern Ghana, West Africa. School pupils aged 12-18 years. Of all adolescents, 31 % took breakfast less than 4 d/week, over half (56 %) and 48 %, respectively, rarely ate fruits and vegetables. Younger adolescents (12-15-year-olds) consumed fruits and vegetables frequently compared with older ones (16-18-year-olds). Boys were more likely to participate in physical activity than girls. The probability of frequent breakfast eating was higher in adolescents from more affluent backgrounds than in those from less affluent ones. Compared with those whose mothers were illiterate, both tertiary and primary maternal educational attainment increased the probability of frequent fruit intake. Similarly, tertiary educational attainment increased the likelihood of frequent vegetable intake. Compared with those with unemployed mothers, mothers' low employment grade was related to higher probability of frequent fruit intake. High school performance was associated with frequent fruit intake, whereas high or medium school performance increased the likelihood of vegetable intake compared with low school performance. Interventions are needed to improve breakfast intake, fruit and vegetable consumption and physical activity in order to prevent degenerative diseases among Ghanaian adolescents.

    Breakfast skipping is associated with increased risk of weight gain and obesity in young adults, possibly due to increased snacking later in the day. Recent research suggests that providing and animal versus a plant source of protein at breakfast can reduce snack intake later in the day. In addition, providing nutrition information via a nutrition label, front-of-pack information, or via text messaging has been shown to help individuals make healthier food choices. The objective of this study was to determine if educational nutrition messaging and protein source influenced snack intake 2 h following the breakfast meal. Participants (n = 33) were randomly assigned to one of two groups: educational nutrition messaging (EM; n = 16) or no messaging (NM; n = 17) group. The study was conducted using a randomized, cross-over design in which each participant received each of two breakfast beverages, whey protein- (WP) and pea protein (PP)- based. Appetite was assessed at 0, 15, 30, 60, 90, and 120 min after each test breakfast using visual analog scales. Participants were then provided with a selection of healthy and unhealthy snacks for 60 min. There was no effect of protein source on appetite or snack intake. However, participants presented with EM had reduced snack intake over the snacking period compared to NM (P = 0.058) and, of the snacks consumed, the EM group consumed a higher percentage of healthy versus unhealthy snacks compared to NM (P snack intake, but EM may help play a role in reducing snack intake between meals.

    The aim of this study was to assess energy, saturated fat and fibre intakes at breakfast among Dutch youngsters aged 10-19 years and the extent to which they meet nutritional value recommendations and the educational messages on food group intake by the Netherlands Nutrition Centre (NNC). A cross-sectional design was used and data were collected through an online questionnaire among 2380 students attending 71 Dutch schools for primary and secondary education. Energy intake at breakfast was, on average, 15.8% of daily recommended energy intake; mean saturated fat intake was 7.5 en% and mean fibre intake 1.0 g per 100 kcal. Of the participants, 67.2% met the saturated fat intake recommendation and 35.3% the fibre intake recommendation. In addition, 25.5% were assessed to have an adequate energy intake based on daily recommended, but not individually measured, age- and gender-specific energy intake. Most participants consumed products from the grains food group, in combination with products from one or two other food groups. Consumption from two or more food groups resulted in less favourable intake. Our study found generally inadequate fibre intake at breakfast as well as an indication of inadequate energy intake at breakfast among Dutch youngsters. The educational message of the NNC to consume at least (wholemeal) bread or another fibre-rich product (cereals) at breakfast seems realistic in terms of compliance and favourable in terms of the resulting nutritional value. The educational message to preferably eat from each of the five main food groups should be reconsidered.

Regular breakfast skipping has been associated with poor diets, higher body mass index, and adverse effects on children's behaviour and academic performance. Research suggests that regular breakfast consumption can improve academic performance, nutrition and behaviour. This paper describes the protocol for a stepped wedge cluster randomised trial of a free school breakfast programme. The aim of the trial is to determine the effects of the breakfast intervention on school attendance, achievement, psychosocial function, dietary habits and food security. Methods/Design Sixteen primary schools in the North Island of New Zealand will be randomised in a sequential stepped wedge design to a free before-school breakfast programme consisting of non-sugar coated breakfast cereal, milk products, and/or toast and spreads. Four hundred children aged 5-13 years (approximately 25 per school will be recruited. Data collection will be undertaken once each school term over the 2010 school year (February to December. The primary trial outcome is school attendance, defined as the proportion of students achieving an attendance rate of 95% or higher. Secondary outcomes are academic achievement (literacy, numeracy, self-reported grades, sense of belonging at school, psychosocial function, dietary habits, and food security. A concurrent process evaluation seeks information on parents', schools' and providers' perspectives of the breakfast programme. Discussion This randomised controlled trial will provide robust evidence of the effects of a school breakfast programme on students' attendance, achievement and nutrition.

  9. Bed, Breakfast and Friendship: Intimacy and Distance in Small-Scale Hospitality Businesses

    2010-09-01

    Full Text Available Through an analysis of the narrative of a Bed and Breakfast (B & B and art gal-lery owner, the emergence of intimacy as a commercial value in the hospitality industry is illustrated. This is a formation of economic value where economic ra-tionality as a motive for commercial activity is rejected. Simultaneously though, a different set of market attitudes are performed by hospitality practitioners in the course of everyday interactions with customers, and a tension between emotional, spatial and temporal intimacy and distance is uncovered and discussed. It is con-cluded that commercial friendship is a more complex issue than what has been acknowledged so far in the hospitality literature.

    There are many complex phenomena that are so familiar to us that we forget to ask whether or not they are understood. In this lecture, I will discuss several familiar cases of effects that are so ubiquitous that we hardly realize that they defy our normal intuition about why they happen. The examples of poorly understood classical physics that I will choose can all be viewed at a breakfast table. I will mention the long tendrils left behind by honey spooned from one dish to another, the anomalous flow behavior of granular material, and the annoying rings deposited by spilled coffee on a table after the liquid evaporates. These are all nonlinear hydrodynamic phenomena which not only are of technological importance but can also lead the inquisitive into new realms of physics. copyright 1999 American Association of Physics Teachers

    Full Text Available The study aimed to evaluate the yield and fruit quality of papaya ‘Sunrise Solo’ as function of nitrogen and boron fertilization. The experiment had a randomized block design with four replications, two plants per plot with a single border. To make up the treatments, we used the experimental array Plan Puebla III, which set the rates for nitrogen (0.0 to 111.2 - 200 – 288.9 - 400 g plant-1, and B (0.0 – 0.83 - 1.5 – 2.16 - 3.0 g plant-1, in a total of ten treatments. The addition of nitrogen increased the yield, average fruit weight and number of fruits per plant. The nitrogen and boron increased the diameter and length of the fruit, amount of seeds and content of soluble solids. The pH of the pulp decreased linearly with increasing doses of nitrogen and boron. It was observed a significant effect of N rates on the level of vitamin C.O trabalho teve como objetivo avaliar a produtividade e a qualidade de frutos de mamoeiro ‘Sunrise Solo’ em função de doses de nitrogênio e boro.

    Breakfast cereals represent the most highly advertised packaged food on child-targeted television, and most ads are for cereals high in sugar. This study examined whether children's TV exposure to child-targeted, high-sugar breakfast cereal (SBC) ads was associated with their consumption of those SBC brands. Parents of 3- to 5-year-old children were recruited from pediatric and Women, Infants, and Children (WIC) clinics in Southern New Hampshire, USA, and completed a cross-sectional survey between April-December 2013. Parents reported their child's consumption of SBC brands; whether their child had watched any of 11 kids' channels in the past week; their child's TV viewing time; and socio-demographics. Children's exposure to child-targeted SBC TV ads was calculated by combining TV channel and viewing time with advertising data for SBC ads aired on kids' TV channels during the same timeframe. Five hundred forty-eight parents completed surveys; 52.7% had an annual household income of $50,000 or less. Children's mean age was 4.4 years, 51.6% were female, and 72.5% were non-Hispanic white. In the past week, 56.9% (N = 312) of children ate SBCs advertised on kids' channels. Overall, 40.6% of children were exposed to child-targeted SBC TV ads in the past week. In fully adjusted analyses, the number of SBC brands children consumed was positively associated with their exposure to child-targeted SBC ads. Children consumed 14% (RR = 1.14, 95% CI: 1.02, 1.27) more SBC brands for every 10 SBC ads seen in the past 7 days. Exposure to child-targeted SBC TV advertising is positively associated with SBC brand consumption among preschool-aged children. These findings support recommendations to limit the marketing of high-sugar foods to young children. Copyright © 2016 Elsevier Ltd. All rights reserved.

  15. Finite element simulation of the compression behaviour of airy breakfast cereals

    KAUST Repository

    Mamlouk, Hedi

    2013-07-01

    In this paper we are concerned by the fragmentation study of five breakfast cereals from the market exhibiting differences in shape, formulation and texture. The experimental part of the study encompasses compression testing and fragment size evaluation using 2D image analysis. Structural information about the airy structure is then determined using X-ray tomography and related 3D image analysis. The numerical part has the ambition of assessing the fragmentation process using a damage-based mechanical model that simulates solid material rupture events as onset and growth of damage up to brittle failure. The model is based on a finite element scheme in which direct information of the 3D airy structure is encoded in the solid meshing. The force-displacement signature well shows competition between bending and compression driven failure depending on cereal shape. Our results show also large dispersion in the porous structure that affects significantly the result of the fragmentation. The numerical model is able to simulate the result of fragmentation at the cost of identifying two mechanical parameters, namely Young\\'s modulus and critical stress. These two quantities are proved to be product dependent and display a large range of variation. Industrial relevance The design of new food product becomes more and more based on functionality criteria. In a typical chewing process the need to understand the deformation mechanisms leading to fragmentation helps in understanding the role of the structure and, in turn, the processing conditions for building new transformed products. There is an increasing industrial demand in that sense especially knowing that some of the cereal products can be designed to meet these criteria for specific populations (old people with dental problems, infant feeding). Our work is, within this context, an attempt to set a numerical and experimental framework for studying the fragmentation of five selected breakfast cereals from the market.

    Energy drinks are widely consumed, and concerns have been raised about possible negative outcomes. The aim of the present research was to examine associations between consumption of energy drinks, caffeine and junk food, and academic attainment in a sample of UK secondary school students. A total of 3071 students agreed to participate in the study; 2677 completed the survey on one occasion (52.4% female, 47.6% male; approximately 20% of the sample from each school year) and 1660 (49.6% female, 50.4% male) completed the survey a second time, approximately six months later. The academic attainment measure was based on Key Stage 3 and Key Stage 4 grades for Maths and English. In the cross-sectional analyses, logistic regressions showed that consumption of energy drinks was associated with a greater likelihood of being in the low academic achievement group. This was not found for other sources of caffeine. The effect of energy drinks was still significant when demographic, academic and health/lifestyle variables were covaried. However, inclusion of an unhealthy diet variable (junk food) removed the significant effect of energy drinks. Similar observations were made in the longitudinal study, with the poorer attainment of those who consumed energy drinks reflecting breakfast omission and depression. The present findings indicate that consumption of energy drinks is associated with an increased likelihood of poor academic attainment that reflects energy drink consumption being part of an unhealthy diet or being associated with skipping breakfast rather than a more specific effect, such as being a source of caffeine. Although the current study extends previous research by utilising a longitudinal design, intervention studies are now required to better answer questions relating to causality and direction of effect.

    Objective To investigate associations of family-related factors with children’s breakfast consumption and BMI-z-score and to examine whether children’s breakfast consumption mediates associations between family-related factors and children’s BMI-z-score. Subjects Ten- to twelve-year-old children (n = 6374; mean age = 11.6±0.7 years, 53.2% girls, mean BMI-z-score = 0.4±1.2) and one of their parents (n = 6374; mean age = 41.4±5.3 years, 82.7% female, mean BMI = 24.5±4.2 kg/m2) were recruited from schools in eight European countries (Belgium, Greece, Hungary, the Netherlands, Norway, Slovenia, Spain, and Switzerland). The children self-reported their breakfast frequency per week. The body weight and height of the children were objectively measured. The parents responded to items on family factors related to breakfast (automaticity, availability, encouragement, paying attention, permissiveness, negotiating, communicating health beliefs, parental self-efficacy to address children’s nagging, praising, and family breakfast frequency). Mediation analyses were performed using multi-level regression analyses (child-school-country). Results Three of the eleven family-related variables were significantly associated with children’s BMI-z-score. The family breakfast frequency was negatively associated with the BMI-z-score; permissiveness concerning skipping breakfast and negotiating about breakfast were positively associated with the BMI-z-score. Children’s breakfast consumption was found to be a mediator of the two associations. All family-related variables except for negotiating, praising and communicating health beliefs, were significantly associated with children’s breakfast consumption. Conclusions Future breakfast promotion and obesity prevention interventions should focus on family-related factors including the physical home environment and parenting practices. Nevertheless, more longitudinal research and intervention studies to

    2009-01-01

    The amount of natural gas resources accessible via proven production technology and existing infrastructure is declining. Therefore, smaller and less accessible gas fields are considered for commercial exploitation. The research project Enabling production of remote gas builds knowledge and technology aiming at developing competitive remote gas production based on floating LNG and chemical gas conversion. In this project, scenarios are used as basis for directing research related to topics that affect the overall design and operation of such plants. Selected research areas are safety, environment, power supply, operability and control. The paper summarises the scenario building process as a common effort among research institutes and industry. Further, it documents four scenarios for production of remote gas and outlines how the scenarios are applied to establish research strategies and adequate plans in a multidisciplinary project. To ensure relevance of the scenarios, it is important to adapt the building process to the current problem and the scenarios should be developed with extensive participation of key personnel.

    Full Text Available En este trabajo presentamos un ejercicio narrativo acerca de la acción social y las teorías hermenéuticas que han intentado definir o hablar acerca de la misma. Se recogen propuestas diversas: desde las que abogan por considerar a la acción social como un texto hasta las consideraciones más pragmatistas acerca del para qué de la acción. En este relato se pone en juego, en el más puro sentido gadameriano, una ficción que tiene la virtud de tematizar y poner en acto, simultáneamente, un concepto que teóricamente ha sido elusivo. Este abordaje asume la sutil noción de narración ficticia que, de acuerdo a Paul Ricoeur, tiene la característica paradójica de que entre más irreal se sitúa una lectura, es más profunda y lejana su influencia sobre la realidad social. Por otro lado, coincidimos con Alfred Schutz en que, al abandonarnos a la risa, hay un ámbito de significado que otorga realidad al mundo ficticio y resignifica el mundo de la vida cotidiana.

  4. Scenario development methods and practice

    International Nuclear Information System (INIS)

    2001-01-01

    The safe management of radioactive waste is an essential aspect of all nuclear power programmes. Although a general consensus has been reached in OECD countries on the use of geological repositories for the disposal of high-level radioactive waste, analysis of the long-term safety of these repositories, using performance assessment and other tools, is required prior to implementation. The initial stage in developing a repository safety assessment is the identification of all factors that may be relevant to the long-term safety of the repository and their combination to form scenarios. This must be done in a systematic and transparent way in order to assure the regulatory authorities that nothing important has been forgotten. Scenario development has become the general term used to describe the collection and organisation of the scientific and technical information necessary to assess the long-term performance or safety of radioactive waste disposal systems. This includes the identification of the relevant features, events and processes (FEPs), the synthesis of broad models of scientific understanding, and the selection of cases to be calculated. Scenario development provides the overall framework in which the cases and their calculated consequences can be discussed, including biases or shortcomings due to omissions or lack of knowledge. The NEA Workshop on Scenario Development was organised in Madrid, in May 1999, with the objective of reviewing developments in scenario methodologies and applications in safety assessments since 1992. The outcome of this workshop is the subject of this book. It is a review of developments in scenario methodologies based on a large body of practical experience in safety assessments. It will be of interest to radioactive waste management experts as well as to other specialists involved in the development of scenario methodologies. (author)

    In recent years an increasing interest is observed with respect to subcritical, accelerator driven systems (ADS), for their possible role in perspective future nuclear energy scenarios, as actinide (Pu and MA) incinerators, and/or claimed energy plants with potential enhanced safety characteristics. Important research programs are devoted to the various related fields of research. Extensive studies on the ADS behavior under incidental conditions are in particular made, for verifying their claimed advantage, under the safety point of view, with respect to the corresponding critical reactors. Corresponding medium and long range scenarios are being studied to cope with a number of concerns associated with the safety (power excursions. residual heat risk), as well as with the fuel flow (criticality accidents, fuel diversion, radiological risk, proliferation). In the present work we shall try to review current lines of research in this field, and comment on possible scenarios so far envisaged. (author)

  8. Scenarios of future energy intensities

    International Nuclear Information System (INIS)

    Anon.

    1992-01-01

    In this chapter, the authors present scenarios of potential change in energy intensities in the OECD countries and in the Soviet Union. These scenarios are meant to illustrate how intensities might evolve over the next 20 years given different conditions with respect to energy prices, energy-efficiency policies, and other key factors. Changes in intensity will also be affected by the rates of growth and stock turnover in each sector. They have not tried to forecast how activity levels and structure will evolve. However, the OECD scenarios assume a world in which GDP averages growth in the 2-3%/year range, with some differences among countries. For the Soviet Union, the degree and pace of intensity decline will be highly dependent on the success of the transition to a market economy; each scenario explicitly envisions a different degree of success. They have not constructed comparable scenarios for the developing countries. The scenarios presented in this chapter do not predict what will happen in the future. They believe, however, that they illustrate a plausible set of outcomes if energy prices, policies, programs, and other factors evolve as described in each case. With higher energy prices and vigorous policies and programs, intensities in the OECD countries in 2010 could be nearly 50% less on average than the level where trends seem to be point. In the former Soviet Union, a combination of rapid, successful economic reform and extra effort to improve energy efficiency might result in average intensity being nearly 40% less than in a slow reform case. And in the LDCs, a mixture of sound policies, programs, and energy pricing reform could also lead to intensities being far lower than they would be otherwise. 8 refs., 10 figs., 1 tab

    The aim of the present study was to investigate the effects of long-term intervention of low-glycaemic-index (GI) v. high-GI breakfasts on energy and macronutrient intakes in children aged 8-11 years. Preadolescent children were assigned to one of two groups in a random cross-over design. Each group was given low-GI and high-GI breakfasts on two non-consecutive days per week for 10 weeks per breakfast type. Each breakfast provided approximately 1273 kJ (300 kcal) and was closely matched for macronutrient and dietary fibre content. Subsequent food intake at an ad libitum buffet lunch was recorded and daily energy and macronutrient intakes were measured by 24 h recall and 3 d food diaries. There was a tendency towards a reduced energy intake at lunch following the low-GI breakfast compared with the high-GI breakfast, although the mean difference of 75 kJ (18 kcal) was not significant (P = 0.406). In particular, there was a trend towards a reduced energy intake in the low-GI arm compared with the high-GI arm among boys. In addition, data from the 3 d food diaries showed that there was a tendency towards a reduced energy intake during the low-GI compared with the high-GI study period. In conclusion, although the difference in energy intake following the low-GI and high-GI breakfasts was not statistically significant, the reduced energy intake following the low-GI breakfast is encouraging. Both dietary fibre and carbohydrate type may affect GI, thus their potential and relative modulating effect on appetite requires further investigation.

    Fibre-rich rye products have been shown to have superior effects on self-reported appetite compared to white wheat bread and some studies have shown lower energy intake after subsequent meal. The aim of the present study was to evaluate the effects of whole grain rye crisp bread (RB) versus refined wheat bread (WB) on appetite in two studies using different portion sizes and total energy intakes. Two randomised cross-over pre-load studies were conducted in 20 and 21 subjects, respectively. Appetite was rated by visual analogue scale (VAS) for 4 h. In both studies, participants were 39 ± 14 years old and had BMI 23 ± 3. The studies differed in terms of energy content of the breakfasts and proportion of energy from the treatment product as well as amount of test products. Differences between treatments within the two studies were evaluated using mixed models with repeated measures appropriate for cross-over designs. In Study one, hunger and desire to eat were significantly lower (P portion size was lower than in Study one and the test product constituted a larger proportion of the breakfast. Fullness was significantly higher after RB compared with WB (P portion was smaller and accounted for a larger proportion of the total energy intake of the breakfast.

    2017-01-01

    Computerized cognitive assessment is becoming increasingly more common in clinical neuropsychological assessment and cognitive neuropsychological research. A number of computerized tasks now exist to assess multitasking abilities that are essential for everyday tasks such as cooking, shopping, or driving, but little is known about whether these tasks are appropriate for assessing older adults' multitasking. The present study directly compared age effects on multitasking when assessed using a computerized and a prop-based version of Craik and Bialystok's ( 2006 ) Breakfast task. Twenty participants aged 18 to 24 years and 20 participants aged 60 to 79 years were assessed on both versions of the Breakfast task. While age-related decrements in multitasking performance were found using the computerized task, significant age differences were not found on the majority of measures when the prop-based version was administered. The results suggest that age-related deficits in multitasking will be less when more contextualized, noncomputer based tasks are used.

    The goal was to determine whether breakfast had effects on the cognitive performance and mood of high school students. A crossover trial was performed in boarding schools, involving 104 students between 13 and 20 years of age. The participants were randomly assigned to 2 equal-size groups on the morning of the first testing day. One half of the total sample received a standardized breakfast, whereas the other half received no breakfast. Seven days later, the treatment order was reversed. Measurements of cognitive function included standardized tests of attention and concentration, as well as tests of verbal and spatial memory. In addition, mood was rated with a self-administered questionnaire covering the dimensions of positive and negative affect, information uptake, arousal, and alertness. Statistical analysis consisted of repeated-measures analysis of variance. Breakfast had no effect on sustained attention among high school students. Visuospatial memory was improved in male students. Self-reported alertness improved significantly in the entire study population. Male students reported feeling more positive after consuming breakfast, compared with the fasting condition. This crossover trial demonstrated positive short-term effects of breakfast on cognitive functioning and self-reported alertness in high school students.

    The beneficial effect of dietary fiber (DF) consumption has long been recognized. The global economy and open market trade policies have increased the availability of food products in Mexican markets, resulting in a wide variety of ready-to-eat commercial breakfast cereals classified as 'high fiber'. This research was aimed to evaluate the total dietary fiber contents, its fractions (soluble and insoluble) and β-glucan in 13 commercial 'high-fiber' breakfast cereals, as well as to evaluate their protein quality by rat bioassays. Commercial 'high-fiber' breakfast cereals had 7.42-39.82% insoluble dietary fiber, 2.53-12.85% soluble dietary fiber, and 0.45-4.96% β-glucan. These ready-to-eat commercial 'high-fiber' breakfast cereals differed significantly in their total dietary fiber, their soluble and insoluble DF fractions, and also in their β-glucan contents. When supplied as experimental diets, in 14-day rat feeding trials, the 'high-fiber' breakfast cereals showed an adverse effect on the % N digestibility but protein utilization, as measured as net protein ratio (NPR), was not significantly affected. The consumption of these commercial breakfast cereals, especially those made of oats as the basic ingredient, is highly recommended, since these products, being a concentrated source of dietary fiber, do not affect their protein quality.

    Few studies exist that have systematically examined the role of protein, and egg protein in particular, in appetite and energy intake regulation in children. The aim of this study was to compare the effects of three different types of breakfast on appetite and energy intake at subsequent meals in children. Forty children, ages 8-10, were served a compulsory breakfast (egg, cereal, or oatmeal) and lunch, consumed ad libitum, once a week for three weeks. Children's appetite ratings were assessed repeatedly throughout the morning. On each test day, caregivers completed food records, which captured children's intake for the remainder of the day. There was a significant main effect of breakfast condition on energy intake at lunch (P=0.02) indicating that children consumed ~70 fewer calories at lunch following the egg breakfast (696 ± 53 kcal) compared to the cereal (767 ± 53 kcal) and oatmeal (765 ± 53 kcal) breakfasts. Calories consumed for the remainder of the day and daily energy intake did not differ across conditions (P>0.30). There also were no significant differences in children's appetite ratings between conditions (P>0.43). Consuming an egg-based breakfast significantly reduced short-term, but not longer-term, energy intake in children in the absence of differences in appetite ratings. Copyright © 2015 Elsevier Ltd.

    Whey proteins have insulinotropic effects and reduce the postprandial glycemia in healthy subjects. The mechanism is not known, but insulinogenic amino acids and the incretin hormones seem to be involved. The aim was to evaluate whether supplementation of meals with a high glycemic index (GI) with whey proteins may increase insulin secretion and improve blood glucose control in type 2 diabetic subjects. Fourteen diet-treated subjects with type 2 diabetes were served a high-GI breakfast (white bread) and subsequent high-GI lunch (mashed potatoes with meatballs). The breakfast and lunch meals were supplemented with whey on one day; whey was exchanged for lean ham and lactose on another day. Venous blood samples were drawn before and during 4 h after breakfast and 3 h after lunch for the measurement of blood glucose, serum insulin, glucose-dependent insulinotropic polypeptide (GIP), and glucagon-like peptide 1 (GLP-1). The insulin responses were higher after both breakfast (31%) and lunch (57%) when whey was included in the meal than when whey was not included. After lunch, the blood glucose response was significantly reduced [-21%; 120 min area under the curve (AUC)] after whey ingestion. Postprandial GIP responses were higher after whey ingestion, whereas no differences were found in GLP-1 between the reference and test meals. It can be concluded that the addition of whey to meals with rapidly digested and absorbed carbohydrates stimulates insulin release and reduces postprandial blood glucose excursion after a lunch meal consisting of mashed potatoes and meatballs in type 2 diabetic subjects.

    Many children do not eat enough whole grains, which may have negative health consequences. Intervention research is increasingly focusing on nudging as a way to influence food choices by affecting unconscious behavioural processes. The aim of this field study was to examine whether the shape of bread rolls is able to shift children's bread choices from white to whole wheat during breakfast to increase whole grain intake. In a between-subjects experiment conducted at twelve primary schools in the Netherlands, with school as the unit of condition assignment, children were exposed to an assortment of white and whole wheat bread rolls, both varying in shape (regular versus fun). Children were free to choose the type and number of bread rolls and toppings to eat during breakfast. Consumption of bread rolls was measured at class level via the number of bread rolls before and after breakfast. In addition, children (N = 1113) responded to a survey including questions about the breakfast. Results of the field experiment showed that about 76% of bread consumption consisted of white bread rolls. Consumption of white bread rolls did not differ according to shape (all P-values > 0.18). However, presenting fun-shaped whole wheat bread rolls almost doubled consumption of whole wheat bread (P = 0.001), particularly when the simultaneously presented white bread rolls had a regular shape (interaction P = 0.02). Survey results suggest that slight increases in perceived pleasure and taste are associated with these effects. Overall, presenting whole wheat bread in fun shapes may be helpful in increasing consumption of whole wheat bread in children. Future research could examine how improving the visual appeal of healthy foods may lead to sustained behaviour changes.

  9. Shell energy scenarios to 2050

    International Nuclear Information System (INIS)

    2008-01-01

    Shell developed two scenarios that describe alternative ways the energy future may develop. In the first scenario (Scramble) policymakers pay little attention to more efficient energy use until supplies are tight. Likewise, greenhouse gas emissions are not seriously addressed until there are major climate shocks. In the second scenario (Blueprints) growing local actions begin to address the challenges of economic development, energy security and environmental pollution. A price is applied to a critical mass of emissions giving a huge stimulus to the development of clean energy technologies, such as carbon dioxide capture and storage, and energy efficiency measures. The result is far lower carbon dioxide emissions. Both these scenarios can help Shell to test their strategy against a range of possible developments over the long-term. However, according to Shell, the Blueprints' outcomes offer the best hope for a sustainable future, whether or not they arise exactly in the way described. However, with the right combination of policy, technology and commitment from governments, industry and society globally, Shell believes it can be realized. But achieving the targets will not be easy, and time is short. Clear thinking, huge investment, and effective leadership are required

    Among adults, skipping meals is associated with excess body weight, hypertension, insulin resistance, and elevated fasting lipid concentrations. However, it remains unknown whether specific eating habits regardless of dietary composition influence coronary heart disease (CHD) risk. The objective of this study was to prospectively examine eating habits and risk of CHD. Eating habits, including breakfast eating, were assessed in 1992 in 26 902 American men 45 to 82 years of age from the Health Professionals Follow-up Study who were free of cardiovascular disease and cancer. During 16 years of follow-up, 1527 incident CHD cases were diagnosed. Cox proportional hazards models were used to estimate relative risks and 95% confidence intervals for CHD, adjusted for demographic, diet, lifestyle, and other CHD risk factors. Men who skipped breakfast had a 27% higher risk of CHD compared with men who did not (relative risk, 1.27; 95% confidence interval, 1.06-1.53). Compared with men who did not eat late at night, those who ate late at night had a 55% higher CHD risk (relative risk, 1.55; 95% confidence interval, 1.05-2.29). These associations were mediated by body mass index, hypertension, hypercholesterolemia, and diabetes mellitus. No association was observed between eating frequency (times per day) and risk of CHD. Eating breakfast was associated with significantly lower CHD risk in this cohort of male health professionals.

    Full Text Available Background. Levothyroxine is commonly used in the treatment of patients with hypothyroidism. Levothyroxine is most often administered in the morning, on an empty stomach, in order to increase its oral absorption. However, many patients have difficulties taking levothyroxine in the morning. Aim. The aim of this study was evaluating the effect of changing levothyroxine administration time from before breakfast to before dinner on the serum levels of TSH and T4. Subjects and Methods. Fifty patients between 18 and 75 years old with hypothyroidism were included in the study and were randomly divided into two groups. Each group received two tablets per day (one levothyroxine tablet and one placebo tablet 30 minutes before breakfast and 1 hour before dinner. After two months, the administration time for the tablets was changed for each group, and the new schedule was continued for a further two-month period. The serum TSH and T4 levels were measured before and after treatment in each group. Results. Changing the levothyroxine administration time resulted in 1.47 ± 0.51 µIU/mL increase in TSH level (p=0.001 and 0.35 ± 1.05 µg/dL decrease in T4 level (p=0.3. Conclusions. Changing the levothyroxine administration time from before breakfast to before dinner reduced the therapeutic efficacy of levothyroxine.

    Nutritional aspects of breakfast, plasma levels of glucose and beta-hydroxybutyrate, body mass index and academic performance have been studied in urban and rural children (Extremadura, Spain). Representative samples of schoolchildren (3 to 12 years old, random cluster-sampling in schools). Children's mean caloric intake with breakfast was 331 kcal. Rural population ingested more carbohydrates (46,9 +/- 12,3% versus 43,3 +/- 13,2% of the total caloric intake) and fewer lipids (40,5 +/- 11,8% versus 43,9 +/- 12,8% of the total caloric intake) than the urban population. Academic performance was significantly better in the children inhabiting the rural zone than in those of the urban zone. The glycaemia was higher in the urban than in the rural children, and that the contrary was the case for the beta-hydroxybutyrate values. Neither glucose nor beta-hydroxybutyrate levels were correlated with academic performance values. BMI was significantly increased in the urban versus rural children. The present results emphasize the importance of breakfast and life style in the weight and the academic performance of children.

    School breakfast programs are widespread and serve varying objectives regarding youth health promotion. Evidence-based guidelines for breakfast programs may be important in maximizing their effectiveness related to student outcomes, yet it is unclear what is available in Canada. A systematic review was conducted to identify and compare Canadian guidelines related to breakfast programs. Data sources included grey literature databases, customized search engines, targeted websites, and content expert consultations. Eligible guidelines met the following criteria: government and nongovernment sources at the federal and provincial/territorial levels, current version, and intended for program coordinators. Recommendations for program delivery were extracted, categorized, and mapped onto the 4 environments outlined in the ANGELO framework, and they were classified as "common" or "inconsistent" across guidelines. Fifteen sets of guidelines were included. No guidelines were available from federal or territorial governments and 4 provincial governments. There were few references to peer-reviewed literature within the guidelines and despite many common recommendations for program delivery, conflicting recommendations were also identified. Potential barriers to program participation, including a lack of consideration of allergies and other dietary restrictions, were identified. Future research should identify how guidelines are implemented and evaluate what effect their implementation has on program delivery and student outcomes.

    Humans can be exposed to multiple chemicals, but current risk assessment is usually carried out on one chemical at a time. Mycotoxins are commonly found in a variety of foods including those intended to consumption by children namely breakfast cereals. The present study aims to perform, the risk assessment of single and multiple mycotoxins present in breakfast cereals consumed by children (1-3 years old) from Lisbon region, Portugal. Daily exposure of children to ochratoxin A, fumonisins and trichothecenes showed no health risks to the children population considering individual mycotoxins, while exposure to aflatoxin B1 (AFB1) suggested a potential health concern for the high percentiles of intake (P90, P95 and P99). The combined exposure to fumonisins and trichothecenes are not expected to be of health concern. The combined margin of exposure (MoET) for the aflatoxins group could constitute a potential health concern and AFB1 was the main contributor for MoET. Legal limits and control strategies regarding the presence of multiple mycotoxins in foodstuffs is an urgent need. To the best of our knowledge, this is the first time a cumulative risk assessment was performed on multiple mycotoxins present in breakfast cereals consumed by children.

    Full Text Available Background: Obesity has become a worldwide epidemic and its prevalence continues to increase at a rapid rate in various populations and across all age-group. The effect of meal skipping, both behaviorally and physiologically, may have an impact on the outcome of weight-loss efforts. Aims and Objectives: Therefore, the aim of this study was to examine the prevalence of breakfast skipping and obesity in subjects. Materials and Methods: A retrospective analysis of the patients visited to a metabolic clinic of the city was done. Results: One hundred and eighty-six eligible subjects were included for the study. A questionnaire was used for data collection which included information regarding dietary factors and exercise schedule/physical activity. A 24-hour dietary recall method was used to assess the amount of food consumed. Anthropometric measurements were taken. Results: Overweight is generally higherin females than males. The prevalence of overweight was higher among those who consumed more than recommended calories than those who were taking recommended or fewer calories per day. The average intake of fat and protein by the study subjects was quite different than the recommended intake of these food items. There was positive association between fat (oil intake and overweight status and a negative association between protein intake and overweight status which was statistically significant. Conclusion: The higher prevalence of overweight and obesity in the present study could be because of imbalance in the diet and faulty food habits prevalent in the region.

    ABSTEACT Despite the reported poor dietary habits and risk of weight gain in college students, they remain understudied in Mexico. Mexican college students are in a rapidly changing economic environment; a shift from a traditional, homemade cuisine to a diet more heavily influenced by an industrialized culture seems to be occurring, potentially affecting the quality of their dietary intake. A health and nutrition survey was conducted among 450 Mexican college students to study the relationship between sociodemographic factors and diet quality. Dietary data were used to build macro- and micronutrient scores, dichotomized as low and normal quality. Adjusted odds (OR [95% CI]) were computed to determine the probability of low dietary quality. Breakfast skipping (5.3 [1.2, 22.7]) and risk of anxiety (2.3 [1.3, 4.4]) were associated with a greater risk of low macronutrient quality, and caloric intake exercise ≤ 1 h/wk (2.6 [1.3, 5.2]), and soda consumption > 250 mL/d (2.0 [1.2, 3.3]) with low micronutrient quality.

    The combined effect of natural antioxidants and packaging materials on the quality decay of breakfast cereals during storage was evaluated. Corn flakes were produced on industrial scale, using different packages and adding natural tocopherols to the ingredients, and stored for 1 year. The samples were then submitted to sensory analysis and HS-solid phase microextraction/gas chromatography/mass spectrometry (SPME/GC/MS) analysis. The packaging had a significant influence on the sensory profile of the aged product: metallized polypropylene gave the highest levels of oxidation compounds and sensory defects. The sensory profile was improved using polypropylene and especially high-density polyethylene. Natural tocopherols reduced the sensory decay of the flakes and the oxidative evolution of the volatile profile. They gave the most remarkable improvement in polypropylene (either metallized or not) packs. Polypropylene showed a barrier effect on the scalping of volatiles outside of the pack. This led to higher levels of oxidation volatiles and faster rates of the further oxidative processes involving the volatiles.

    Full Text Available Objective: To assess the school breakfast program (SBP in two schools with high Aboriginal student populations in rural Western Australia, their contribution to holistic support, nutritional health education and possibilities for improvement. Methods: The operations and functioning of one regional and one remote SBP were assessed by stakeholder inquiry related to process and challenges, observations and documentary review. An intervention to increase health education, social interaction and learning about nutrition and food origins implemented in one school was assessed. Results: Strengths, system and structural factors that impeded realisation of optimal outcomes of the SBPs were identified. The SBPs focussed on serving food rather than building nutritional understanding or on social interactions and support. Systems for delivery and management of the programs largely relied on staff with limited time. When offered a more interactive and social environment, children enjoyed learning about food. Conclusions: Opportunities for SBPs to offer holistic support and educational enhancement for disadvantaged children are limited by the realities of pressures on staff to support them and a view constraining their primary role as food delivery. The lack of volunteer support in disadvantaged schools limits the potential benefits of SBPs in providing psychosocial support. Health education resources which exist for use in SBPs are not necessarily used.

    Various eating behaviors have been linked with body weight management. However, combined effects of major eating behaviors are not fully understood. This study aimed to clarify the association of the combination of eating quickly (EQ), late evening meals (LEM), and skipping breakfast (SB) with being overweight. A cross-sectional study with standardized questions for EQ, LEM, and SB was conducted. Stratified random sampling of 5% of residents aged 20 to 80years was surveyed in a city in northeast Japan in 2011, and 4249 (84.9%) residents were analyzed. Association of combinations of eating behaviors on being overweight (BMI (kg/m(2)≥25.0)) was estimated by using logistic analysis, and odds ratio (OR) and 95% confidential interval were calculated after adjustment for potential covariates. LEM, SB, or a combination of LEM and SB was not significantly associated with being overweight. However, the combination of EQ or only EQ was significantly associated with being overweight. As the number of eating behavior practices increased, there was a linear increase in OR for being overweight. The OR of all three combined eating behaviors was higher than that of any combined two behaviors or of each behavior. This study result supports the evidence that EQ increases the risk of being overweight whether by itself or in combinations with LEM and/or SB. However, only LEM or only SB did not increase the risk of being overweight. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To assess the school breakfast program (SBP) in two schools with high Aboriginal student populations in rural Western Australia, their contribution to holistic support, nutritional health education and possibilities for improvement. The operations and functioning of one regional and one remote SBP were assessed by stakeholder inquiry related to process and challenges, observations and documentary review. An intervention to increase health education, social interaction and learning about nutrition and food origins implemented in one school was assessed. Strengths, system and structural factors that impeded realisation of optimal outcomes of the SBPs were identified. The SBPs focussed on serving food rather than building nutritional understanding or on social interactions and support. Systems for delivery and management of the programs largely relied on staff with limited time. When offered a more interactive and social environment, children enjoyed learning about food. Opportunities for SBPs to offer holistic support and educational enhancement for disadvantaged children are limited by the realities of pressures on staff to support them and a view constraining their primary role as food delivery. The lack of volunteer support in disadvantaged schools limits the potential benefits of SBPs in providing psychosocial support. Health education resources which exist for use in SBPs are not necessarily used.

    Low-glycaemic index diets reduce glycated Hb (HbA1c) in patients with type 2 diabetes, but require intensive dietary support. Using a liquid meal replacement with a low glycaemic response (GR) may be an alternative dietary approach. In the present study, we investigated whether breakfast replacement with a low-GR liquid meal would reduce postprandial glycaemia and/or improve long-term glycaemia. In the present randomised, controlled, cross-over design, twenty patients with type 2 diabetes consumed either a breakfast replacement consisting of an isoenergetic amount of Glucerna SR or a free-choice breakfast for 3 months. Postprandial AUC levels were measured using continuous glucose measurement at home. After the 3-month dietary period, meal profiles and oral glucose tolerance were assessed in the clinical setting. The low-GR liquid meal replacement reduced the AUC of postprandial glucose excursions at home compared with a free-choice control breakfast (estimated marginal mean 141 (95 % CI 114, 174) v. estimated marginal mean 259 (95 % CI 211, 318) mmol × min/l; P= 0·0002). The low-GR liquid meal replacement also reduced glucose AUC levels in the clinical setting compared with an isoenergetic control breakfast (low GR: median 97 (interquartile range (IQR) 60-188) mmol × min/l; control: median 253 (IQR 162-386) mmol × min/l; Pmeal replacement did not affect fasting plasma glucose, HbA1c or lipid levels, and even slightly reduced oral glucose tolerance. In conclusion, the low-GR liquid meal replacement is a potential dietary approach to reduce postprandial glycaemia in patients with type 2 diabetes. However, clinical trials into the effects of replacing multiple meals on long-term glycaemia in poorly controlled patients are required before a low-GR liquid meal replacement can be adopted as a dietary approach to the treatment of type 2 diabetes.

  4. Base case and perturbation scenarios

    This report describes fourteen energy factors that could affect electricity markets in the future (demand, process, source mix, etc.). These fourteen factors are believed to have the most influence on the State's energy environment. A base case, or most probable, characterization is given for each of these fourteen factors over a twenty year time horizon. The base case characterization is derived from quantitative and qualitative information provided by State of California government agencies, where possible. Federal government databases are nsed where needed to supplement the California data. It is envisioned that a initial selection of issue areas will be based upon an evaluation of them under base case conditions. For most of the fourteen factors, the report identities possible perturbations from base case values or assumptions that may be used to construct additional scenarios. Only those perturbations that are plausible and would have a significant effect on energy markets are included in the table. The fourteen factors and potential perturbations of the factors are listed in Table 1.1. These perturbations can be combined to generate internally consist.ent. combinations of perturbations relative to the base case. For example, a low natural gas price perturbation should be combined with a high natural gas demand perturbation. The factor perturbations are based upon alternative quantitative forecasts provided by other institutions (the Department of Energy - Energy Information Administration in some cases), changes in assumptions that drive the quantitative forecasts, or changes in assumptions about the structure of the California energy markets. The perturbations are intended to be used for a qualitative reexamination of issue areas after an initial evaluation under the base case. The perturbation information would be used as a "tiebreaker;" to make decisions regarding those issue areas that were marginally accepted or rejected under the base case. Hf a

    Major projection studies by international organizations and senior analysts have been compared with reference to individual key parameters (population, energy demand/supply, resources, technology, emissions and global warming) to understand trends and implications of the different scenarios. Then, looking at the long term (i.e., 2050 and beyond), parameters and trends have been compared together to understand and quantify whether and when possible crisis or market turbulence might occur due to shortage of resources or environmental problems [it

    After a brief analysis of the history of global energy consumption, this paper discusses a plausible scenario of energy needs and related carbon emissions for the rest of the century. The global outlook and the probable evolution of several factors that impact on energy policy considerations - even on the local scale - demonstrate the great complexity and planetary dimension of the problems, as well as the almost certain sterility of out-of-context domestic energy-policy measures [it

    In thermonuclear fusion research using magnetic confinement, the tokamak is the leading candidate for achieving conditions required for a reactor. An international experiment, ITER is proposed as the next essential and critical step on the path to demonstrating the scientific and technological feasibility of fusion energy. ITER is to produce and study plasmas dominated by self heating. This would give unique opportunities to explore, in reactor relevant conditions, the physics of {alpha}-particle heating, plasma turbulence and turbulent transport, stability limits to the plasma pressure and exhaust of power and particles. Important new results obtained in experiments, theory and modelling, enable an improved understanding of the physical processes occurring in tokamak plasmas and give enhanced confidence in ITER achieving its goals. In particular, progress has been made in research to raise the performance of tokamaks, aimed to extend the discharge pulse length towards steady-state operation (advanced scenarios). Standard tokamak discharges have a current density increasing monotonically towards the centre of the plasma. Advanced scenarios on the other hand use a modified current density profile. Different advanced scenarios range from (i) plasmas that sustain a central region with a flat current density profile (zero magnetic shear), capable of operating stationary at high plasma pressure, to (ii) discharges with an off axis maximum of the current density profile (reversed magnetic shear in the core), able to form internal transport barriers, to increase the confinement of the plasma. The physics of advanced tokamak discharges is described, together with an overview of recent results from different tokamak experiments. International collaboration between experiments aims to provide a better understanding, control and optimisation of these plasmas. The ability to explore advanced scenarios in ITER is very desirable, in order to verify the result obtained in

  8. Scenarios for the LHC Upgrade

    2008-01-01

    The projected lifetime of the LHC low-beta quadrupoles, the evolution of the statistical error halving time, and the physics potential all call for an LHC luminosity upgrade by the middle of the coming decade. In the framework of the CARE-HHH network three principal scenarios have been developed for increasing the LHC peak luminosity by more than a factor of 10, to values above 1035 cm−2s−1. All scenarios imply a rebuilding of the high-luminosity interaction regions (IRs) in combination with a consistent change of beam parameters. However, their respective features, bunch structures, IR layouts, merits and challenges, and luminosity variation with β∗ differ substantially. In all scenarios luminosity leveling during a store would be advantageous for the physics experiments. An injector upgrade must complement the upgrade measures in the LHC proper in order to provide the beam intensity and brightness needed as well as to reduce the LHC turnaround time for higher integrated luminosity.

    Full Text Available The effects of blast waves generated by energetic and non-energetic sources are of continuing interest to the ballistics research community. Modern conflicts are increasingly characterised by asymmetric urban warfare, with improvised explosive devices (IEDs often playing a dominant role on the one hand and an armed forces requirement for minimal collateral effects from their weapons on the other. These problems are characterised by disparate length- and time-scales and may also be governed by complex physics. There is thus an increasing need to be able to rapidly assess and accurately predict the effects of energetic blast in topologically complex scenarios. To this end, this paper presents a new QinetiQ-developed advanced computational package called EAGLE-Blast, which is capable of accurately resolving the generation, propagation and interaction of blast waves around geometrically complex shapes such as vehicles and buildings. After a brief description of the numerical methodology, various blast scenario simulations are described and the results compared with experimental data to demonstrate the validation of the scheme and its ability to describe these complex scenarios accurately and efficiently. The paper concludes with a brief discussion on the use of the code in supporting the development of algorithms for fast running engineering models.

    In 2011, IRENA will start developing scenarios and strategies for Africa. This is a pilot study for a project that will ultimately encompass the whole world. The selection of Africa first indicates the priority that the IRENA work programme places on the continent. In the framework of the 2011 IRENA work programme, the analysis of scenarios and strategies will feed into the renewables readiness assessment, which will assess policy priorities and best practices in renewable energy policy-making. This, in turn, will be the basis for financing investment and capacity building activities. Energy policy advice must consider issues, such as the structure of energy supply and demand, the past and future energy trends, renewable energy resources, energy economics and technology access. Scenarios and strategies are key tools for such an analysis. Regional and national differences must be considered and individual sectors and end-use categories further analysed. These include power generation, cooking, heating, industrial process heat, and transport. Urban and rural solutions will be dealt with separately, as well as centralised and decentralised solutions. The analysis will cover issues, such as potentials, technology, supply chains and investment needs.

    Few studies on impact of meals served in school have been published. However, implications of school meals are an actual issue of both public and political concern in several countries. The objective of this study was to evaluate if breakfast served in a lower secondary school could improve dietary habits and school performance among the students. All students in 10th grade in a lower secondary school, consisting of two school classes, were invited to participate in a controlled study. The students in one class were offered a free breakfast at the beginning of each school day for 4 months, while the students in the second class were controls. Both classes were educated in the importance of healthy eating, and a data program enabling them to evaluate dietary intake was introduced. The students answered two questionnaires, one on school performance and one short food frequency questionnaire, four weeks before study start and one week after. Body weight and height were measured by the school nurse at the beginning and end of the study. Because of few students in each group, non-parametrical statistic analyses were used. All students in the intervention group had breakfast at school during the intervention. One week after the intervention the students in the class who received breakfast had returned to their normal breakfast pattern. In the control group the frequency of a lunch intake had increase, as compared to before study start (p school performance following school breakfast was not found, but the males in the intervention group reported a significant increase in school contentment (p school class served breakfast for 4 months, dietary intake changed to a more healthy profile and weight gain was reduced.

    Full Text Available The effects of an enzyme-hydrolyzed arabinoxylan from wheat (AXOS versus an intact arabinoxylan from flax (FLAX added to a ready-to-eat cereal (RTEC on the postprandial appetitive, hormonal, and metabolic responses in overweight women (BMI 25.0–29.9 kg/m2 were evaluated. Subsequent meal energy intake was also assessed. Two randomized, double-blind, crossover design studies were completed. For trial 1, the participants consumed the following RTEC breakfast, matched for total weight and varied in energy content: low-fiber (LF, 4 g; high-fiber (HF, 15 g as either AXOS or FLAX. For trial 2, the participants consumed LF, HF-AXOS, and HF-FLAX RTECs but also consumed another LF breakfast that was isocaloric (LF-iso to that of the HF breakfasts. Perceived appetite and blood samples (trial 2 only were assessed before and after breakfast. An ad libitum lunch was offered 4 h post-breakfast. No differences in postprandial appetite responses were observed among any breakfasts in either trial. The HF-AXOS and HF-FLAX led to increased postprandial GLP-1 and peptide YY (PYY concentrations vs. LF-iso. No differences were observed in lunch meal energy intake among breakfast meals in either trial. Collectively, these data suggest that 15 g of low molecular weight fiber added to RTECs did not affect perceived appetite or subsequent energy intake despite differences in satiety hormone signaling in overweight females.

    Eating breakfast is crucial for adolescents to be healthy. It also improves students' capacity of learning and doing school homework. Although healthy habits such as eating breakfast, weight control, and regular sleep increase the lifespan in adults, the effects of healthy habits on school-age children have not been studied much. The present study aimed at investigating the impact of an educational program based on Theory of Planned Behavior (TPB) on eating breakfast among middle school students. This interventional study was conducted on sixth-grade students in Qom City during the academic year 2012-2013. First, 97 students were randomly assigned to the experimental group and 97 other students were assigned to the control group. Then, a questionnaire was developed on eating breakfast by the researchers according to the TPB. A pilot study was conducted to assess the reliability of the questionnaire. To assess the validity of the questionnaire, advice by a panel of experts was sought. To carry out a pre-test, both groups answered the questions. After analyzing the pre-test results, the required content was developed for the experimental group. Educational methods included delivering speech, discussion groups, pamphlets, and posters. The required educationalcontent was provided for students during five sessions and for parents in one session. To determine the effect of educational intervention, a post-test study was carried out 2 months after the intervention. Collected data were analyzed using independent t-test, χ,([2]) and repeated measures. In the experimental group, 36.7% of students were eating breakfast at least in a day of a week, before educational intervention. After implementation of the educational program, only 32.7% of them were continuing their past habit. There was a significant difference between themean scores of attitudes, perceived behavioral control, intention, and practice of eating breakfast in the experimental and control groups (P students

    Full Text Available Recognizing the importance of nutrition as part of the grand challenges faced by humanity—the current epidemic of non-communicable diseases (NCDs, sustainability and maintenance of Planetary Health—the United Nations (UN has declared 2016–2025 the Decade of Nutrition. Research continues to underscore the extent to which ultra-processed foods dominate the contemporary nutritional landscape. Moreover, the dual role played by food technology and marketing in the expansion of ultra-processed foods is under increased scrutiny. As public health experts and clinicians contend with a crisis of NCDs, attempting to untangle a knotted assortment of interrelated strands of causation, an examination of the early origins of highly-marketed ultra-processed foods can provide valuable lessons. Here, we illuminate a little-known piece of history in the annals of ultra-processed nutritional science and childhood welfare. Astrofood was a commercially-marketed, collaborative government-industry effort that brought soy protein-enriched Twinkies as a nutritive breakfast cake to disadvantaged children; its concept and delivery demonstrated an unwillingness to deal with root-cause challenges. Although its official tenure was only about 7 years, we argue that Astrofood and its total food engineering still resonate throughout the global ultra-processed nutritional landscape. New scientific advances in nutritional psychiatry and the microbiome are on a collision course with the profits, marketing and intellectual dishonesty of the ultra-processed food industry. Solutions to the grand challenges of the Decade of Nutrition may be found in lessons from Astrofood. They provide clues to undoing the tangled knots which otherwise maintain an untenable status quo.

    This project aims primarily to give a basis for the joint R and D program for the Swedish electric utility industry, in the form of pictures of the future up to 2020. The work was performed during four seminars in a group of managers and R and D planners. The four scenarios differ mainly in the assumptions of high or low economic growth and on market or political rule. Assumptions on essential uncertainties about the future have been combined in a consistent manner, e.g. on the structure of the utility industry, the role of nuclear power, the importance of the greenhouse gas issue, the influence of new technology developments and on changes of values in society. Certain other development appear in all scenarios, e.g. the impact of information technology throughout society, the internationalization of business in general and industrial production in particular, considerations for the environment and care for natural resources. The four scenarios are: `Technology on the throne` (market rule/high growth); `Intense competition` (market rule/low growth); `Monopoly takes over` (political rule/high growth); and `Green local society` (political rule/low growth). Some of the important factors pointed out by the study are: Increased customer mobility between regions and countries; The impact of information technology; Societal value changes; Sustainable development as an important driving force; Structure of the utility industry. Diversifying into new services. New players; Access to knowledge and competence; Ways for handling the greenhouse gas problem; Preparedness for nuclear power phase-out. 12 figs, 6 tabs

    This study reports on the results of an assignment from the DOE Office of Civilian Radioactive Waste Management to evaluate of the effects of different scenarios for receipt of spent fuel on the potential performance of the waste packages in the proposed Yucca Mountain high-level waste repository. The initial evaluations were performed and an interim letter report was prepared during the fall of 1988. Subsequently, the scope of work was expanded and additional analyses were conducted in 1989. This report combines the results of the two phases of the activity. This study is a part of a broader effort to investigate the options available to the DOE and the nuclear utilities for selection of spent fuel for acceptance into the Federal Waste Management System for disposal. Each major element of the system has evaluated the effects of various options on its own operations, with the objective of providing the basis for performing system-wide trade-offs and determining an optimum acceptance scenario. Therefore, this study considers different scenarios for receipt of spent fuel by the repository only from the narrow perspective of their effect on the very-near-field temperatures in the repository following permanent closure. This report is organized into three main sections. The balance of this section is devoted to a statement of the study objective, a summary of the assumptions. The second section of the report contains a discussion of the major elements of the study. The third section summarizes the results of the study and draws some conclusions from them. The appendices include copies of the waste acceptance schedule and the existing and projected spent fuel inventory that were used in the study. 10 refs., 27 figs

    Increasing either protein or fiber at mealtimes has relatively modest effects on ingestive behavior. Whether protein and fiber have additive or interactive effects on ingestive behavior is not known. Fifteen overweight adults (5 female, 10 male; BMI: 27.1 ± 0.2 kg/m²; aged 26 ± 1 year) consumed four breakfast meals in a randomized crossover manner (normal protein (12 g) + normal fiber (2 g), normal protein (12 g) + high fiber (8 g), high protein (25 g) + normal fiber (2 g), high protein (25 g) + high fiber (8 g)). The amount of protein and fiber consumed at breakfast did not influence postprandial appetite or ad libitum energy intake at lunch. In the fasting-state, visual food stimuli elicited significant responses in the bilateral insula and amygdala and left orbitofrontal cortex. Contrary to our hypotheses, postprandial right insula responses were lower after consuming normal protein vs. high protein breakfasts. Postprandial responses in other a priori brain regions were not significantly influenced by protein or fiber intake at breakfast. In conclusion, these data do not support increasing dietary protein and fiber at breakfast as effective strategies for modulating neural reward processing and acute ingestive behavior in overweight adults.

    Dietary therapy is the mainstay of treatment for diabetes. This study examined the effect of a low glycemic index (GI) multi-nutrient supplement, consumed in place of breakfast, on glycemic control in patients with type 2 diabetes mellitus (T2DM). A total of 71 participants were randomized at a 2:1 ratio into either a breakfast replacement group or a normal breakfast group for a 12-week interventional study. The primary outcome measure was change in hemoglobin A1c (HbA1c). Nutrition status and somatometry were studied as secondary outcomes. The breakfast replacement group displayed a -0.2% absolute reduction in HbA1c (95% CI (confidence interval), -0.38% to -0.07%, p = 0.004), while the HbA1c of the control group increased 0.3% (95% CI, 0.1% to 0.5%, p = 0.005). The baseline Mini Nutritional Assessment score for both groups was 26.0 and no significant changes occurred following intervention. However, there was a statistically significant difference in body mass index between the treatment and control groups (p = 0.032) due to the weight gain in the control group (increased 0.5 kg, 95% CI was 0.2 to 0.9, p = 0.007). These data suggest that breakfast replacement with a low GI multi-nutrient supplement can improve glycemic and weight control in T2DM.

    This study examined the effects of breakfast eating and eating frequency on objectively assessed BMI and weight loss outcomes among adults enrolled in obesity treatment. Participants completed measures of breakfast eating and eating frequency before and after treatment and had their height and weight measured. Baseline breakfast eating and eating frequency were not associated with baseline BMI (p = .34, p = .45, respectively) and did not predict weight loss during treatment (p = .36, p = .58, respectively). From pre- to post-treatment, there was no significant change in eating frequency (p = .27) and changes in eating frequency had no impact on weight loss (r = -.08, p = .23). However, increases in breakfast eating during treatment were associated with significantly better weight loss outcomes (r = .26, p eating, those who had either no change or a decrease in daily eating frequency were more likely to achieve a 5% weight loss compared to those who had an increase in daily eating frequency (p = .04). These results suggest that increasing breakfast eating, while simultaneously reducing or keeping eating frequency constant, may improve outcomes in obesity treatment. Experimental studies are needed to further elucidate these effects.

  20. Comparing recent uranium supply scenarios

    For more than one decade – even after the Fukushima accidents - an increase in global nuclear energy generation capacity is widely expected. At the same time a variety of uranium supply scenarios were published by industry, academics or international organizations, drawing different pictures of future uranium supply. They were created with the background of a uranium market facing several challenges. First an excursion in the uranium market price, in 2007, then reduced nuclear growth expectations after 2011, at least in non-Asian countries, also implying considerable changes to the supply side. For this publication a meta-study was carried out identifying, evaluating and comparing different recent scenarios on the availability of uranium. While there are some differences in the frame conditions (e.g. the expected uranium demand, the time fame, the considered mining projects,..), there are also notable similarities in these scenarios. This concerns long lead times for mine openings as well as the dependence on large mining projects (e.g. Olympic Dam, Cigar Lake). Generally, a decline in production in about 10 years is assumed, and thus the necessity of the timely development of mining projects is pointed out. In addition the omission of uranium from Russian nuclear weapons and the chances of keeping the changes in secondary supplies in balance with primary production have been widely discussed. Here, the production growth in Kazakhstan but also the role of the current market situation are central aspects. As another aspect the possible contribution from unconventional resources is of interest, particularly against the background of rising production costs for conventional resources. Finally, it shall be reflected how well older scenarios were able to map the reality and which trends could or could not be anticipated. It is relevant to identify which aspects in the development of mining capacities are essential for security of supply, and can therefore be regarded
