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

Sanches, Michele 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.

Objetivo: Evaluar la asociación entre mayor uso de cepillo dental, pasta dental y frecuencia de cepillado en los niños menores de 12 años afiliados al programa Qali Warma en el Perú durante el 2018. Metodología: Se realizó un estudio observacional, retrospectivo, transversal y analítico de 17556 niños < 12 años que participaron de la Encuesta Nacional Demográfica y de Salud Familiar 2018. Las variables dependientes fueron el uso de cepillo dental, pasta dental y la frecuencia de cepillado, e independiente fue la afiliación al programa Qali Warma. Se utilizó el programa STATA® v16 para el análisis descriptivo, bivariado y multivariado con pesos estadísticos. Se compararon las variables categóricas, calculando prevalencias con la prueba chi cuadrado y para las numéricas, las medias mediante la prueba T student. Para la asociación de variables, se calcularon las razones de prevalencia e intervalos de confianza al 95% utilizando modelos de regresión de Poisson. Resultados: La prevalencia de niños afiliados a Qali Warma que se cepillan dos veces o más al día fue de 82.3%. No se encontró una asociación entre el uso del cepillo dental, pasta dental ni frecuencia de cepillado con la afiliación de los niños menores de 12 años al programa Qali Warma al controlar por todas las covariables. Conclusiones: El estar afiliado al programa Qali Warma no tiene asociación sobre el uso de cepillo dental, pasta dental y el cepillado de dos veces o más al día en los niños peruanos menores de 12 años. / Objective: To evaluate the association between greater use of toothbrush, toothpaste, and frequency of brushing in children under 12 years old affiliated to the Qali Warma program in Peru during 2018. Methodology: An observational, retrospective, cross-sectional and analytical study was carried out on 17,556 children < 12 years old who participated in the 2018 National Demographic and Family Health Survey. The dependent variables were the use of toothbrush, toothpaste and brushing frequency and the independent, affiliation to the Qali Warma program. The STATA® v16 program was used to perform descriptive, bivariate, and multivariate analysis with statistical weights. Categorical variables were compared, calculating prevalence with the chi square test and for numerical variables, the means were calculated using the T student test. For the association of variables, prevalence ratios and 95% confidence intervals were calculated using Poisson regression models. Results: The prevalence of children affiliated to Qali Warma brushing 2 or more times a day was 82.3%. No association was found between the use of toothbrush, toothpaste or brushing frequency with the affiliation of children under 12 years old to the Qali Warma program when controlling for all covariates. Conclusions: Being affiliated to the Qali Warma program has no association with the use of toothbrush, toothpaste, and brushing twice or more a day in Peruvian children under 12 years old. / Tesis
