Initially, 165 vegetable gardens were identified spread over the city, of which, 57 were randomly chosen to have 5 unit samples examined, reaching a total of 285 vegetable units analyzed from each vegetable garden from July/99 to May/00. A unit sample was considered the whole plant independent of the size or weight. The parasite search was done through the spontaneous sedimentation in water and the centrifugal-flotation on zinc sulfate used to wash the units. A questioner was used to obtain the epidemiological data. In 100% of the vegetable gardens, at least one unit was contaminated. The following parasites were found on 73.3% of lettuces: Strongyloides sp (66,7%), ancylostomideous (17.5%), Ascaris lumbricoides (3.2%), Entamoeba sp, Trichuris sp, Isospora sp, Iodameba butschi (1.1%); Taenia sp, Toxocara sp (0.7%) and Shistosoma mansoni (0.4%). Among the positive samples, 54.4% had one single species and 18.9% had 2 or 3 different parasites identified. The Strongyloides prevalence presented statistical significance (p<0.05) for the absence of vegetables cleaning before exit and for worker’s age, and income. The other risk factors such as untreated irrigation water, proximity to pools and pollutes, accentuated ground sloping, the usage of untreated organic fertilizer, the presence of flying vectors and domestic animals, and the inexistence of inappropriate place for fecal evacuation by the workers, reached no statistic significance, despite the possible contribution to the elevated numbers that were found; that was probably related to the homogeneous ecologic conditions observed in the majority of the kitchen gardens studied. / O presente trabalho teve como objetivo determinar a prevalência de enteroparasitos em hortaliças, mais especificamente a alface (Lactuca sativa) de hortas comerciais e de uso coletivo no município de Fortaleza-CE e associá-la aos fatores ambientais, higiênico-sanitários e sócio-econômicos locais. Inicialmente foram cadastradas, através de um censo, 165 hortas em Fortaleza, dentre as quais 57 foram escolhidas aleatoriamente para o estudo. Cinco unidades de alface (Lacuta sativa) foram obtidas por horta, totalizando uma amostra de 285 hortaliças. Considerou-se como unidade amostral, 01 pé ou touceira, independente do peso ou tamanho, colhidas ao acaso. O exame parasitológico das unidades foi realizado através do método de sedimentação espontânea em água e o de centrífugo-flutuação em sulfato de zinco empregados ao lavado das hortaliças e um questionário foi utilizado para obtenção dos dados epidemiológicos. Em 100% das hortas estudadas, uma ou mais amostras estavam contaminadas com enteroparasitos. Foi encontrada uma positividade em 73,3% das amostras de alface examinadas, sendo diagnosticados ovos e larvas de helmintos e cistos de protozoários, dentre estes: Strongyloides sp (66,7%), Ancilostomídeos (17,5%), Ascaris lumbricoides (3,2%), Entamoeba sp, Trichuris sp, Isospora sp, e Iodameba butschilii (1,1%); Taenia sp e Toxocara sp (0,7%); e Shistosoma mansoni (0,4%). Dentre as amostras parasitadas, 54,4% apresentaram uma espécie de parasito, enquanto que 18,9% apresentaram duas ou três. A prevalência de Strongyloides sp apresentou significância estatística (p<0,05) apenas para idade e renda dos trabalhadores das hortas. Os demais fatores como uso de água não tratada na irrigação, proximidades com coleções hídricas e poluentes, solos com declives acentuados, uso de adubo orgânico sem nenhum tipo de tratamento, presença de vetores e animais domésticos e inexistência de local adequado para os trabalhadores das hortas evacuarem, apesar de poderem ter contribuído para a elevada prevalência observada, não atingiram significância estatística. Tal fato pode ser explicado pela homogeneidade das condições ecológicas que foram precárias na maioria das hortas.

Objetivo: Evaluar el consumo de frutas y verduras en una población peruana mayor de 15 años en adelante. Diseño: Se realizará un estudio exploratorio, que consiste en realizar un análisis secundario de la base de datos del estudio poblacional tipo transversal que proviene de la Encuesta Demográfica y de Salud Familiar (ENDES), realizada en los últimos años.

Belo Horizonte, MG, Brasil / O consumo adequado de frutas e hortaliças (FH) tem sido apontado como um dos fatores de proteção de doenças crônicas não transmissíveis, como enfermidades cardiovasculares, diabetes e obesidade. Apesar das evidências e orientações para a ingestão deste grupo de alimentos, o seu consumo é ainda bastante limitado. Esta situação expõe a necessidade de investigar os determinantes do consumo de FH visando o melhor delineamento das práticas educativas e de promoção da saúde. Para cumprir este objetivo, realizou-se uma pesquisa qualitativa em seis polos do Programa Academia da Saúde em Belo Horizonte, Minas Gerais. Participaram da pesquisa 62 usuários maiores de 20 anos e responsáveis pela aquisição e/ou preparo dos gêneros alimentícios no domicílio. Os dados foram coletados por entrevista semiestruturada, incluindo questões relativas às práticas alimentares na família, consumo e aquisição de FH. As entrevistas foram gravadas, transcritas na íntegra e tiveram duração média de 30 minutos. A análise de conteúdo foi desenvolvida com auxílio do software NVivo10. O consumo de FH era estimulado principalmente pelo seu efeito benéfico sobre a saúde, capacidade em prevenir/controlar doenças e paladar. Já os facilitadores para o consumo de hortaliça relatados foram: ser considerada como parte da refeição, criação e origem familiar, melhoria da situação financeira, comércio próximo e desenvolvimento de estratégias de compra. Com relação aos fatores dificultadores do consumo, destacaram-se: comércio inadequado, baixo poder aquisitivo, preço, carência de iniciativas públicas, falta de tempo, preguiça, fruta ser considerada apenas como uma alternativa alimentar e não realizar o jantar. As FH eram adquiridas em comércios de bairros, havendo necessidade de melhoria desses estabelecimentos em relação à distribuição geográfica, qualidade dos produtos, preço e higiene. Verificou-se que, quando os aspectos nutricionais das FH eram valorizados pelos entrevistados, o conhecimento básico que possuíam sobre alimentação e saúde era considerado insuficiente, surgindo a demanda pelo aprofundamento dos saberes. A dificuldade em lidar com a multiplicidade de informações sobre o tema gerava sentimentos de desconfiança, incompetência para selecionar os alimentos e desejo por orientação especializada individual. Estes resultados apontam para a necessidade de estimular a construção de sentidos para o consumo de FH que não se restrinjam ao discurso saúde-doença; problematizar questões sobre o consumo de FH que geram inquietações, desconfianças e insegurança; estabelecer canais de comunicação confiáveis; ampliar habilidades culinárias para o preparo de receitas baratas, práticas e palatáveis; qualificar o comércio local; e ampliar o acesso às FH pelo desenvolvimento ou fortalecimento de políticas públicas e tecnologias que promovam conveniência. / Consumption of adequate amounts of fruits and vegetables (FV) has been considered as one of the protective factors of chronic diseases such as cardiovascular diseases, diabetes and obesity. However, despite the evidence and guidelines to encourage the intake of this food group, its consumption has been very limited. This exposes the need to investigate the determinants of FV consumption for a better design of educational and health promotion practices. To fulfill this goal, a qualitative study was made in six groups of the Health Academy Program in Belo Horizonte, Minas Gerais. There were 62 participants. Data was collected through semi-structured interview, whose script included questions relating to eating habits in the family, consumption and acquisition of FV. The interviews were recorded, transcribed and had an average duration of 30 minutes. The content analysis was developed with the use of NVivo10 software. The consumption of fruits and vegetables was mainly stimulated by the beneficial health effects, ability to prevent / control diseases, taste, vegetable be considered as part of the meal, creation and family background, improving the financial situation, next trade and development purchasing strategies. Regarding the barriers, the highlights were: inadequate trade, low purchasing power, price, lack of public enterprises, lack of time, laziness, fruit be considered only as a food alternative and not do dinner. Fruits and vegetables were acquired in trades neighborhoods, and it is necessary improvement of these establishments in the geographical distribution, product quality, price and hygiene. It was found that as the nutritional aspects of FV gain value among respondents, existing knowledge about the relationship between health and FV consumption is seen as insufficient, resulting in the demand for the deepening of knowledge. The difficulty in dealing with this information generates feelings of distrust, inability to select foods and desire for individual expert guidance. Considering the results, there was the need to stimulate the construction of meaning for consume FV that are not limited to discourse of health and disease; discuss issues on the FV consumption that generate uneasiness, mistrust and insecurity; establish channels of reliable sources; enlarge culinary skills to prepare cheap, practical and palatable recipes; qualifying local businesses; expand access to FH through the development or strengthening of public policies and investment in technologies that ensure convenience.

Sólo el 5% de ellas consumía 5 o más porciones diarias, la mayoría (61,3%) consumía 1 a 2 porciones. Principales motivaciones para comer 5 porciones fueron: “me gustan”, “para perder peso”. Principal barrera “se me olvida comerlas”. En actividad física, el 33,1% señaló encontrarse en la etapa de mantenimiento y el 18,9% en acción. Principales motivaciones: “me hace sentir bien”, “para perder peso”. Principal barrera: “no tengo tiempo”. Se sugiere que las intervenciones educativas consideren las actitudes y creencias de las madres, para ser más efectivas / In order to design effective interventions for childhood obesity prevention, the stages of change, motivations and barriers related to the consumption of five daily portions of fruit and vegetables and physical activity were determined in 323 preschool mothers attending Primary Health Centers, through the application of a previously validated survey. Only 5% of them consumed 5 or more portions, the majority (61.3%) consumed 1 to 2 portions. The main motivations to eat 5 portions were: “I like them” and “To lose weight”. The main barrier was “I forget to eat them”. With respect to physical activity, 33.1% considered themselves on the maintenance stage and 18.9% on the action stage. Main motivations were: “Makes me feel good”, “To lose weight”. Main barrier: “I don’t have time”. It is suggested that educational interventions consider the mother attitudes and beliefs, to be more effective.

El análisis del efecto de las variables individuales y contextuales fue medido a partir de la utilización de un modelo multinivel, construido en tres niveles de análisis: para la conformación del primer nivel se consideró la información relacionada a las características socioeconómicas y demográficas de los individuos seleccionados por la ENFR, como segundo nivel las variables provinciales provenientes de los censos nacionales y de la ENFR y en el tercer nivel las variables agrupadas a nivel de región, disponibles en la ENFR. (...) Conclusión: En este análisis fue posible observar un efecto, aunque pequeño, de la variabilidad explicada a nivel provincial y regional en el consumo de frutas y verduras, a pesar de que las variables socioeconómicas y demográficas provinciales elegidas no tuvieron gran poder explicativo sobre el resultado encontrado. El ejercicio aquí planteado abre una futura línea de investigación que ahondará en los determinantes de esa variabilidad, siendo necesario explorar que variables de nivel 2 y 3, o incluso variables con menor nivel de desagregación (departamental, municipal o barrial), pueden ayudar a recoger características de estos contextos y cuya presencia pueden contribuir a la reducción de la variabilidad de consumo de frutas y verduras no explicada hasta el momento.

The analysis of the effect of both individual and contextual variables was measured by using a multilevel model, built on three analysis levels: for the conformation of the first level, it has been considered the information related to the socio-economic and demographic characteristics from the individuals selected by the ENFR; for the second level, the provincial variables from the national census and the ENFR; and for the third level, the variables gathered at regional level from the ENFR. (...) Conclusion: From this analysis, it could be observed the effect, even though low, of the variability observed at provincial and regional level on fruits and vegetables consumption, despite the fact that the selected socioeconomic and demographic provincial variables did not have a great explanatory power on the results. The hereby proposed exercise opens a future research line that can deepen those variables determinants, making it necessary to explore which variables at levels 2 and 3, or also variables with a lower disaggregation level (at departmental, municipal or neighborhood level) can help to gather those context features and whose presence can contribute to the reduction of the variability of fruits and vegetables consumption not explained until the moment.

No. of bitstreams: 1 Oliveira_GiovannaPisanelliRodriguesde_D.pdf: 765185 bytes, checksum: 9235741dc430626ebbcdfbedd46a07ad (MD5) Previous issue date: 2011 / Abstract: Carotenoids are among the phytochemicals of greater interest in terms of human health benefits. Brazil has the largest database on carotenoid concentrations, but studies on bioavailability are lacking. Chapter 1 is a review of the literature describing the mechanism of digestion, transport and absorption of carotenoids, the factors that can affect bioavailability and the in vivo and in vitro methods used for determining bioavailability. In vitro methods have been developed to determine bioaccessibility of carotenoids rapidly and inexpensively, but comparative evaluation of the different methods has not been carried out. Chapter 2 presents a comparison of the results obtained by a methodology for the determination of bioaccessibility in vitro and with modifications suggested to simulate human physiology better. The bioaccessibility of the carotenoids of carrot, tomato, and raw and cooked New Zealand spinach was, in general, significantly greater when the method of Reboul et al. (2006) was used. The oral phase proposed to integrate the digestion in vitro before the gastric phase did not alter the bioaccessibility of the carotenoids of the samples studied, but the addition of lipase and carboxyl ester lipase increased the bioaccessibility. The homogeneization time also affects significantly the percent micelarization of the carotenoids. Chapter 3 presents the bioaccessibility of commercial and native leafy vegetables, aside from the evaluation of the effect of cooking on bioaccessibility. Among the raw samples analyzed, New Zealand spinach had the highest bioaccessibility for ß-carotene (14%) and lutein (46%), correlating with its low fiber content (2.1 g/100g). The native leaf ¿caruru¿, richer in fiber (4.5 g/100g) had the lowest bioaccessibility for ß-caroteno (2.3%) and for lutein (6.9%). Cooking increased the bioaccessibility for ß-carotene (3.3 to 16% and 14 to 15%, respectively) and lutein (18 to 38% and 46 to 59%, respectively) in kale and New Zealand spinach. The bioaccessibility of carotenoids in fruits and their processed derivatives was studied in Chapter 4. Among the raw fruits, the papaya 'Solo¿ had the highest bioaccessibility for ß-carotene (36%) and ß-cryptoxanthin (39%) and pitanga had the lowest bioaccessibility for these carotenoids (6.3% e 10%, respectively). The percent micelarization of carotenoids was higher in the processed products. In mango, the bioaccessibility for ß-carotene increased from 19% in the raw fruit to 57% in the juice, and in guava , the bioaccessibility of lycopene increased from 1.4% to 27% in ¿goiabada¿. Chapter 5 deals with the bioaccessibility of the Amazonian fruits ¿buriti¿, ¿tucuma¿ and pupunha (raw and cooked). Aside from being excellent sources of provitamin A carotenoids (150, 142, 48 µg/g of ß-carotene for ¿tucuma¿, ¿buriti¿ and ¿pupunha¿, respectively), all three fruits presented greater bioaccessibility of ß-carotene than those of the fruits analyzed in the previous chapter, the cooked¿pupunha¿ having the highest percentage (40%). Chapter 6 provides inforrmation about the bioaccessibility of pitanga pulp and pitanga microencapsulated with different wall materials to protect the carotenoids from oxidative degradation. Lycopene had low bioaccessibility (1%) in all samples analyzed. Lutein was the most bioaccessible carotenoid in all samples (6 a 21%). Micelarization with maltodextrin substantially decreased the bioaccessibilitiy of all the carotenoids, while there was practically no loss of bioaccessibility with gum Arabic. The modified starch had an intermediate effect / Doutorado / Doutor em Ciência de Alimentos

Introdução: Frutas, legumes e verduras (FLV) contêm vários nutrientes com efeitos favoráveis para a saúde humana. Dentre estes, o folato é um dos nutrientes chaves envolvido na manutenção da saúde, com um potencial papel na redução das concentrações plasmáticas de homocisteína (hcy), reconhecido marcador de doença cardiovascular. Objetivos: Investigar o consumo de FLV, segundo características sóciodemográficas, antropométricas e de estilo de vida e relacionar o consumo de FLV e de folato com os níveis sanguíneos de hcy em adolescentes. Métodos: Este estudo utilizou dados de adolescentes de ambos os sexos, faixa etária de 12 a 19 anos, obtidos no Inquérito de Saúde ISA - Capital, realizado periodicamente no Município de São Paulo. O consumo de FLV foi estimado no estudo realizado em 2003, cuja amostra foi de 812 participantes. Para avaliação das relações entre FLV, folato e hcy, foram utilizados dados coletados no segundo ISA-Capital, entre os anos de 2008-2010 com amostra de 183 adolescentes. O consumo de FLV e de equivalentes de folato dietético (DFE), bem como o consumo de folato natural e ácido fólico, foram estimados por um recordatório de 24h. A análise bioquímica das concentrações plasmáticas de hcy foi realizada pelo método de cromatografia líquida. O ponto de corte de hcy plasmática utilizado foi de <8 mol/L para indivíduos com menos de 15 anos e <12 mol/L para indivíduos entre 15 e 19 anos. A concentração média de hcy plasmática foi descrita de acordo com os tercis de consumo de FLV, segundo as características sócio-demográficas, antropométricas e de estilo de vida. Todas as análises estatísticas foram realizadas no STATA® versão 10.0 considerando o nível de significância 5 por cento . Resultados: No primeiro estudo (2003) 20 por cento dos adolescentes não consumiram FLV no dia relatado e 6,5 por cento apresentaram consumo adequado. Renda, escolaridade do chefe da família e tabagismo influenciaram este consumo. Já no segundo estudo (2008-2010), 56 por cento não consumiram FLV e somente 4,9 por cento atingiram as recomendações. A prevalência de hiperhomocisteinemia na população estudada foi de 9,2 por cento . Adolescentes de 12 a 15 anos apresentaram menores valores de hcy (6,9mol/L) em comparação com os de 16 a 19 anos (8,4mol/L). Não foram encontradas diferenças significativas nos níveis plasmáticos de hcy analisados por tercis de consumo de FLV segundo características sócio-demográficas, de estilo de vida e antropométricas. Os alimentos que mais contribuíram com o consumo de DFE foram: pães (38,4 por cento ), seguidos pelo feijão (11,7 por cento ) e massas (10,1 por cento ). Para folato natural os alimentos de maior contribuição foram: feijão (30,3 por cento ), FLV (14,9 por cento ) e pães (14,6 por cento ); e, para o ácido fólico, se destacaram pães (53,3 por cento ), massas (14,6) e biscoitos (9,8 por cento ). Conclusão: O consumo de FLV por adolescentes está muito abaixo das recomendações nas duas amostras estudadas e não influenciou as concentrações plasmáticas de hcy / Background: Fruits and vegetables (FV) contains multiple nutrients with beneficial effects for human health. Among these, folate is one of the key nutrients involved in maintaining health, with a potential role in reducing plasma concentrations of homocysteine (hcy), recognized marker of cardiovascular disease. Objectives: To investigate the FV intake, according to socio-demographic, anthropometric and lifestyle characteristics and to relate the FV and folate intake with blood levels of hcy in adolescents. Methods: This study used data from adolescents of both sexes, aged 12 to 19, enrolled in the Health Survey ISA - Capital, periodically held in São Paulo. The FV intake was estimated in the study conducted in 2003, comprising 812 participants. To assess the relationship between FV, folate and hcy, we used data collected in the ISA Capital, conducted between the years 2008-2010 with a sample of 183 adolescents. The FV intake and dietary folate equivalents (DFE), as well as natural folate and folic acid intake, were estimated by a 24-hour recall. Biochemical analysis of plasma hcy was performed by liquid chromatography. The cutoff point for plasma hcy was <8 mmol/L for individuals younger than 15 years and <12 mmol/L for individuals aged between 15 and 19 years. The average concentration of plasma hcy was described into tertiles of FV intake, according to the socio-demographic, anthropometric and lifestyle characteristics. All statistical analyzes were performed in STATA ® version 10.0 with 5 per cent of significance level. Results: In the first study (2003) 20 per cent of adolescents not consumed FV on day evaluated and only 6.5 per cent had adequate intake. Per capita household income, head of familys level and smoking habit influenced this consumption. In the second study (2008-2010), 56 per cent not consumed FV and only 4.9 per cent met the recommendations. The prevalence of hyperhomocysteinemia was 9.2 per cent . Adolescents aged 12 to 15 years had lower levels of hcy (6.9 mmol/L) compared with 16 to 19 years (8.4 mmol/L). No significant differences were found in plasma levels of hcy into tertiles of FV intake according to socio-demographic, lifestyle and anthropometric characteristics. Foods that most contributed to DFE intake were bread (38.4 per cent ), followed by beans (11.7 per cent ) and pasta (10.1 per cent ). For natural folate, the foods that most contributed were: beans (30.3 per cent ), FV (14.9 per cent ) and breads (14.6 per cent ), and for folic acid, breads (53.3 per cent ), pasta (14.6) and biscuits (9.8 per cent ). Conclusion: FV intake by adolescents is below the recommendations and not influenced plasma concentrations of hcy
