Hortaliças: consumo e preferências de escolares. / Vegetables: consumption and students preferences.

Michele Sanches 14 January 2003 (has links)
Análises elaboradas nas últimas três décadas, tendo por base dados obtidos por pesquisas nacionais revelam que houve redução do consumo, pela população brasileira, de alimentos de origem vegetal. Também tem sido destacado por diversos autores que o baixo consumo de frutas e hortaliças está associado ao maior risco do desenvolvimento de doenças cardiovasculares e diversos tipos de câncer. Pesquisas envolvendo crianças e adolescentes brasileiros revelam que os mesmos consomem, de forma geral, reduzida quantidade desses alimentos. Com o objetivo de estimular o consumo dos alimentos de origem vegetal, têm sido buscadas alternativas e, entre essas, a incorporação de maior quantidade e variedade dos referidos alimentos nas refeições dos programas alimentares dirigidos, por exemplo, aos escolares. Uma alternativa que se revela promissora é a utilização dos alimentos minimamente processados, também considerados de "conveniência" ou de "fácil preparo". A presente pesquisa, realizada no município de Piracicaba – SP e tendo por base amostra de 210 escolares, matriculados em escolas públicas, visou conhecer: a aceitabilidade das hortaliças minimamente processadas; a análise do consumo de alimentos, com destaque para a contribuição de energia e nutrientes provenientes das hortaliças e frutas e, também, a avaliação do estado nutricional dos alunos. Foram analisados os indicadores antropométricos (escore Z de altura para idade – ZAI e escore Z de peso para idade – ZPI) e a distribuição do Índice de Massa Corporal – IMC. As informações relativas ao consumo alimentar (análises quantitativas e qualitativas) foram obtidas por meio da realização de entrevistas, adotando-se o método de registro de alimentos (Recordatório 24 horas). Para o cálculo e as análises do conteúdo de energia e nutrientes presentes na alimentação dos escolares utilizou-se o software Virtual Nutri (Philippi et al., 1996). Para conhecer a opinião do grupo de alunos sobre as hortaliças minimamente processadas, realizou-se teste de análise sensorial, adotando-se a escala hedônica facial de três pontos. Os resultados revelaram que dos alunos entrevistados, 35,2% das meninas e 32,4% dos meninos apresentaram sobrepeso enquanto apenas 1,9% dos escolares revelaram condição oposta, ou seja, baixo peso. Verificou-se que 50% da população estudada possui dieta cujo conteúdo energético não atingiu o valor mínimo recomendado e, somente 36,19% dos escolares apresentaram adequada participação dos macronutrientes (carboidratos, proteínas e lipídios) no Valor Energético Total – VET. Observou-se também, que 58,10% dos participantes da pesquisa gostaram muito das hortaliças minimamente processadas, e apenas 10,47% reprovaram os vegetais. verificou-se que 17,14% das meninas e apenas 3,81% dos meninos, afirmaram "não gostar" das hortaliças minimamente processadas. Ressalta-se que 61% dos escolares que revelaram "gostar muito" dos vegetais minimamente processados, pertencem a famílias com menor renda per capita. Há possibilidades que uma maior oferta e consumo de hortaliças, pelos alunos, seja assegurada com a devida incorporação de alimentos minimamente processados às refeições dos programas alimentares, que vigoram atualmente no Brasil. / Analysis elaborated in the last three decades, based on information obtained through national researches reveal that there was reduction of the consumption, for the Brazilian population, of foods of vegetable origin. It has also been highlighted by several authors that the low consumption of fruits and vegetables is associated to a larger risk of development of cardiovascular diseases and several cancer types. Researches involving children and Brazilian teenagers reveal that they consume, in general, reduced amount of those foods. With the objective of stimulating the consumption of the foods of vegetable origin, alternatives have been looked for and, among those, the incorporation of a larger amount and variety of the referred foods in the meals of the alimentary programs driven to the scholars, for instance. An alternative, which seems promising, is the use of the minimally processed vegetables, also considered of "convenience" or "easy to prepare". This research, accomplished in the municipal district of Piracicaba – SP, based on a sample of 210 students, enrolled in public schools, aimed to know: the acceptability of the minimally processed vegetables; analyze the consumption of foods; highlighting the contribution of energy and nutrients coming from vegetables and fruits and, also, the students' nutritional status. The anthropometrical indicators were analyzed (Z - scores of height to age – ZAI and Z – scores of weight for age - ZPI) as well as the distribution of the Body Mass Index - BMI. The information concerning the alimentary consumption (quantitative and qualitative analysis) was obtained through interviews, being adopted the method of registration of foods (Reminding 24 hours). For the calculation and analysis of the content of energy and nutrients present in the students feeding it was used the software Virtual Nutri (Philippi et al., 1996). To know the opinion of the students' group on the minimally processed vegetables, a sensorial analysis took place, adopting the three points facial hedonic scale. The results revealed that, among the interviewed students, only 35,2% of the girls and 32,4% of the boys presented overweight while 1,9% of the students revealed the opposite condition, that is, low weight. It was verified that 50% of the studied population have a diet in which energy content didn't reach the recommended minimum value and, only 36,19% of the students presented appropriate participation of the macronutrients (carbohydrates, proteins and lipids) in the Total Energy Value – TEV. It was also observed that 58,10% of the participants of the research enjoyed a lot the minimally processed vegetables, and only 10,47% didn't enjoy the vegetables. It was verified that 17,14% of the girls and only 3,81% of the boys stated not to "enjoy" the minimally processed vegetables. It is important to say that 61% of the students who revealed to "enjoy a lot" the minimally processed vegetables, belong to families that have a smaller family income per capita. There are possibilities that a larger offer and consumption of vegetables, among the students, is guaranteed with the incorporation of minimally processed foods to the meals of the alimentary programs in place in Brazil today.

A Study Of The Relationship Between Second-order Change Leadership Behaviors Of Principals And School Grades Of Florida Title I Elementary Schools

La Cava, Gonzalo 01 January 2009 (has links)
The purpose of this study was to determine the relationship between second-order change leadership behaviors and the grade assigned to schools in large urban districts by the Florida Department of Education (FLDOE). A total of 101 Title I elementary school principals from large urban school districts with 60+% students on Free and Reduced School Lunch participated in the study. Specifically, this study analyzed 7 of the 21 second-order change factor responsibilities. They include (a) knowledge of curriculum, instruction, assessment, (b) optimizer, (c) intellectual stimulation, (d) change agent, (e) monitoring/evaluating, (f) flexibility, and (g) ideals/beliefs. The findings of this study were delineated through an examination of the data as it was related to the following questions: (a) What are the differences, if any, in the Principal Actions Survey scores of Title I elementary principals based on the 2008 school grade, according to the FLDOE? (b) What relationship, if any, exists among professional demographics of the principals (years at the school, years as an educator, years as an administrator prior to becoming a principal, years as a principal, highest degree earned, age, gender) and the second-order change leadership behaviors? (c) What are the differences, if any, in the second-order change leadership behavior subgroup scores based on the 2008 school grade according to the FLDOE? Although Research Question 1 had no statistical significance, principals who had a higher mean on the Principal Actions Survey led A and B-rated schools. Statistical significance was found in Research Question 2 for the second-order change leadership behavior of Change Agent and Ideals/Beliefs. Though statistical significance was not found in Research Question 3, each mean score for each sub-group in each grade group indicated consistent answers between Strongly Agree and Agree, which demonstrated a large degree of agreement. Additionally, comments from telephone interviews with selected principals determined that these leadership behaviors could positively impact elementary schools and the field of education. Recommendations of the study were to: (a) Conduct a follow-up study to gather the perceptions of teachers from the same Title I schools regarding their principals' second-order change leadership behaviors, (b) conduct a similar study with principals in Title I middle and high school settings, (c) conduct a qualitative study on second-order change leadership behaviors of non-Title I elementary, middle, and high school principals, (d) engage in further research to investigate professional development activities that may assist principals in enhancing second-order change leadership behaviors and improve instruction, (e) investigate the relationship between principals' second-order change leadership behaviors and achievement of Adequate Yearly Progress (f) replicate the study in states other than Florida (g) explore the relationship between second-order change leadership behaviors of district administrators and their district's academic success.

Hygiene and nutritional content of the National School Nutrition Programme in Bloemfontein, South Africa

Nhlapo, Nthabiseng January 2013 (has links)
Thesis (M. Tech. (Environmental Health)) -- Central University of technology, Free State, 2013 / Malnutrition and concomitant infections are major contributing factors to child morbidity and mortality in developing countries such as South Africa. Globally, children benefiting from school feeding programmes are generally from communities with low socio-economic statuses. The meals provided through feeding schemes, such as the National School Nutrition Programme (NSNP) in South Africa, are aimed at significantly supplementing the beneficiaries’ daily energy and nutrient requirements. The possible nutrient deficiency of meals provided through such programmes compromises the nutritional well-being of children, promotes malnutrition and renders children more susceptible to infectious diseases. Furthermore, illness, particularly caused by diarrhoeal and infectious diseases, is a major factor contributing to child malnutrition as the human body is unable to efficiently digest foods and absorb nutrients during illness. Therefore, the microbiological safety of the foods served to children via feeding schemes is essential. In an effort to contribute towards the safety and wholesomeness of foodstuffs served through the NSNP, the present study was conducted with a view to assess the nutritional quality and safety of the foodstuffs. The knowledge, attitudes and practises (KAP) of food handlers and NSNP representatives/committee members at the schools were also investigated in order to assess origins of potential food contamination. Data collected via nutritional analyses of meals served to school children were compared to the nutrient-based standards set by the United Kingdom as guidelines for an average school lunch. The carbohydrate, energy, calcium and zinc contents of the school meals were below the standards, the majority of the meals met the protein and iron standards and all meals complied with the standards for lipid and vitamin C contents. During the microbiological analysis study, preparation surfaces yielded higher counts of all detected organisms (total coliforms, Escherichia coli, Staphylococcus aureus and yeasts and moulds) compared to the hands of food handlers. Therefore possible sources of contamination may be foodstuffs, animal pests and environmental elements such as dust. However, significant differences of surface microbial counts could not be established (P > 0.05) and thus cross-contamination may have resulted among surfaces, possibly augmented by shortfalls in cleaning regimes. The majority of the participants of the questionnaire survey reportedly washed their hands and cleaned all surfaces several times during the day with water and detergent. In addition, a disinfectant was used by some of the food preparers during cleaning. Furthermore, participants stated that their aprons were washed daily. These claims were in agreement with the findings of the surface microbial study with regards to the hands, however, they did not match the findings of the preparation surfaces which contained the highest counts of total coliforms, E. coli and S. aureus of the three surfaces analysed, and aprons responsible for the highest yeast and mould counts. Improper storage and food preparation methods, such as the application of high temperatures, excessive exposure to UV light and oxygen, and high moisture conditions, may result in the deterioration of nutrients. Storage conditions which may permit pest infestation may also increase the risk of food-related illnesses and risk could be further elevated by application of improper cleaning and sanitation practices. In order for the NSNP to operate effectively, it is essential that the national and provincial Departments of Basic Education, which are responsible for the overall administration of the NSNP, and schools’ personnel function in an integrated manner through support structures and effective communication. Infrastructural limitations (lack of proper kitchen facilities and ventilation) and shortage of resources while administering the NSNP were the main challenges observed during the present study. Due to these hurdles, adhering to food safety practices and maintaining nutritional quality of foods may be a challenge. Continuous training in personal and general hygiene is also a necessity in preserving food safety. Furthermore, nutritional quality of foodstuffs may be preserved through proper storage practices and application of preparation methods which minimize loss of nutrients.

Comportements alimentaires de jeunes utilisateurs de boîte à lunch, selon des mères québécoises

Mondou, Julie-Michèle 05 1900 (has links)
Objectif. Étudier les comportements alimentaires des enfants utilisateurs de boîte à lunch tels que décrits par les mères, en s’inspirant des descripteurs de comportements alimentaires de Jean-Pierre Poulain. Méthodes. Des entrevues individuelles et de groupes eurent lieu avec 18 mères. Une analyse de données qualitatives a été réalisée en utilisant les dimensions de Poulain comme cadre de référence. Une considération additionnelle fut intégrée dans l’analyse, celle de la dimension matérielle de la boîte à lunch. Résultats. Dimension spatiale : Les repas ont lieu dans des classes ou dans de grandes salles communes. Dimension temporelle : Le moment et la durée de la consommation du repas varient selon différents facteurs. Le moment de préparation de la boîte est aussi d’intérêt. Environnement social : Les pairs et les médias ont une grande influence dans les comportements liés à la boîte à lunch. Logique de choix : La mère est le principal décideur et acteur à l’égard du contenu. Structure de la prise : Les mères précisent des contenus associés aux repas de la veille ou des mets froids. Des desserts et des à-côtés accompagnent le repas principal. L’étude de la dimension matérielle de la boîte révèle que la facilité d’entretien est le principal critère de choix des boîtes alors que l’apparence visuelle est celui de l’enfant. L’écologie devient de plus en plus une priorité. Conclusion. Cette nouvelle approche pour l’étude des comportements alimentaires du jeune utilisateur de boîte à lunch fournit aux intervenants une autre perspective selon laquelle étudier cette activité quotidienne et/ou élaborer des projets promotionnels en santé publique. / Objective. To improve the understanding of the eating behaviour of children, relative to lunch boxes, as described by their mothers and taking into consideration the contribution of Jean-Pierre Poulain’s six descriptors of human food behaviour. Methods. Individual and group interviews were conducted with 5 dietitians and 13 mothers. Qualitative analysis has been done using Poulain’s descriptors, on the eating behaviour of children and their lunch boxes. The material dimension of the lunch box was also considered. Results. Space dimension : Meals are eaten into classrooms or in large areas designed for that matter. Temporal dimension : The time and the duration of the activity varies, depending on different factors. Moment and time involve preparing the lunch box is also of interest. Social environment : Peers and media in general have an important influence on the behaviour of lunch baggers. Logic of choice : The mother is the key decision maker and actor with regards to the lunch box content. Content : Lunch can be related to last meals leftovers or home made sandwiches, side dishes and desserts are also of interest. Analysis of comments associated to the lunch box material dimension reveals the importance of ease of cleaning as a key factor for the mothers. Visuals appearance is the most important factor for the kids. Environment becomes a growing concern. Conclusion. This new way of looking at the food behaviour of young lunch box users may help public health educators to inform and assist the actors involve in this daily activity and/or develop public health promotion program.

Současné problémy školního stravování v ČR a vize jeho dalšího vývoje / Current problems of school meals in the Czech republic and the vision of its future development

Strosserová, Alena January 2017 (has links)
Abstracts This thesis will address current problems in terms of school feeding in the Czech Republic. Its purpose is to summarize the situation from the point of view of the heads of school cafeterias and to determine the greatest difficulties for further functioning of the system. School feeding system is a part of educational and learning process and its effects relate to proper fulfilling of schools' educational programmes. At the same time, it is an environment for application of informal learning in terms of correct eating habits and social interactions during meals. By participating in the process, the pupils gain socio-psychological competences for entire life. Not only they gain practical knowledge in terms of nutrition, they learn as well how to interact during meals in an unforced way. Using the questionnaire method, some of the problems of school feeding system were identified. Some of the most severe problems might become a risk to this whole unique system. The outcome of the research are findings which point out the problems, such as old age of the personnel in the school feeding system, as well as the absence of new young people, who would continuously take on the experiences and replace the retiring workers. The results of the research revealed that the case of these problems are mainly...

Essays in Applied Microeconomics

Simroth, Dora 06 August 2015 (has links)
Die erste Arbeit untersucht die Einschulungseffekte des indischen Midday Meal Scheme, das größte Schulessenprogramm der Welt. Um die kausalen Effekte der Strategie zu isolieren, benutzen wir die schrittweise Implementierung des Programms in Indiens Staaten in öffentlichen, aber nicht privaten Schulen. Wir finden einen substanziellen Zuwachs der Einschulung an Grundschulen. Die zweite Arbeit untersucht die Korrelation zwischen unternehmerischem Versuch und Startup und lokaler religiöser Diversität. Wir finden heraus, dass die Orte mit höherer religiöser Diversität mit einer höheren individuellen Wahrscheinlichkeit assoziiert sind, ein neues Unternehmen zu versuchen zu gründen, aber nicht es zum Erfolg zu führen. Die dritte Arbeit modelliert einen Markt in dem Konsumenten gegenüber den Arbeitern Altruismus empfinden und ein wohliges Gefühl davon ableiten, Produkte von Firmen zu kaufen, die zumindest einen Mindestlohn bezahlen. Symmetrische reine Strategie Equilibria werden analyisiert in einem Zufalls-Nutzenmodell mit einem Kontinuum an Konsumenten und n Firmen. / The first paper is a large-scale assessment of the enrollment effects of India''s midday meal scheme, the largest school feeding program in the world. To isolate the causal effect, we make use of staggered implementation across Indian states in public but not private schools. We find a substantial increase in primary school enrollment. The second paper studies the correlation between entrepreneurial trial and startup and local religious diversity. We find that localities with higher religious diversity are associated with a higher individual probability of trying to set up a new venture, but not of setting it up. The third paper models a market where consumers feel altruism towards workers and derive a warm-glow from buying products of firms that pay at least a minimum wage. Symmetric pure-strategy equilibria are analyzed in a random utility model with a continuum of consumers and n firms.
