Efeito do treinamento aquático no perfil lipídico e na hipertrofia ventricular esquerda de camundongos hiperlipidêmicos

This study assessed the effects of Water training on the lipid profile and left ventricular structures in hyperlipidemic mice. Twenty-eight male LDLr-/- mice were randomly separated into 4 groups: sedentary, fed a standard diet (C); exercising, fed a standard diet (C+TRE); sedentary, fed a hyperlipidic diet (C+HL); and exercising, fed a hyperlipidic diet (E+HL). The exercising mice trained daily for 60 minutes during 60 days. After 48 hours of the end of the training period and 12 hours of rest fasting the animals were underwent euthanasia and the blood was collected for measuring the plasma levels of triglycerides, total cholesterol and its fractions (LDL, HDL, VLDL). The heart was removed and the left ventricle was weighed fresh to calculate the ratio left-ventricle weight (mg)/body weight (g). The results showed that the training was more effective in improving lipid plasma levels when combined with a balanced diet, thereby confirming that it is essential to associate physical exercise and diet. The training protocol resulted in eccentric left ventricular hypertrophy in the standard-diet group and decreased interstitial collagen deposition in the myocardium of the high-fat-diet animals, which may indicate an improved diastolic function with consequent improvement in the systolic function. It was concluded that regular moderate aerobic exercise induce beneficial and prophylactic adaptations to heart which promoted a better health condition and prevention to diseases.

Polyphenols in fruits and vegetables and its effect on human health

Polyphenols represent a group of chemical substances common in plants, structurally characterized by the presence of one or more phenol units. Polyphenols are the most abundant antioxidants in human diets and the largest and best studied class of polyphenols is flavonoids, which include several thousand compounds. Numerous studies confirm that they exert a protective action on human health and are key components of a healthy and balanced diet. Epidemiological studies correlate flavonoid intake with a reduced incidence of chronic diseases, such as cardiovascular disease, diabetes and cancer. The involvement of reactive oxygen species (ROS) in the etiology of these degenerative conditions has suggested that phytochemicals showing antioxidant activity may contribute to the prevention of these pathologies. The present review deals with phenolic compounds in plants and reports on recent studies. Moreover, the present work includes information on the relationships between the consumption of these compounds, via feeding, and risk of disease occurrence, i.e. the effect on human health. Results obtained on herbs, essential oils, from plants grown in tropical, subtropical and temperate regions, were also reported.

Nutrient Intake of Women 3 Years After Roux-en-Y Gastric Bypass Surgery

Nutritional deficiencies, especially micronutrient deficiencies, can occur in obese individuals. Surgical treatment may aggravate or cause these deficiencies, depending on the type of procedure, food intake and the use of multivitamins, minerals or other supplements. The objective of the study was to evaluate the nutrient intake of women who had undergone Roux-en-Y gastric bypass (RYGB) surgery. A cross-sectional, controlled study was conducted among 44 women after RYGB (operated-group, OG; mean years post-operation = 3.4) and a control group of 38 healthy women (non-operated group, NOG) matched by age and economic condition. The women reported their dietary intake using a 4-day record. The Dietary Reference Intakes was used as a reference. The macronutrient contributions to dietary energy intake presented an acceptable distribution for proteins and carbohydrates. Lipid intake was high among women in the OG and the NOG (43.2 and 55.3 %, respectively). In the evaluation of micronutrients, a statistically significant difference was observed between the groups for iron, zinc and vitamins B1 and B12. Both groups were at high risk for inadequate calcium intake, and the OG was at risk for inadequate zinc, iron and vitamin B1 intake. The nutrient intake of women who had undergone RYGB is very similar to that of non-operated women, with the exception of a reduced intake of iron, zinc and vitamins B1 and B12, which may be due to the difficulty of consuming meat and a balanced diet. The findings of this study emphasize the importance of appropriate nutritional intervention and the regular use of multivitamin and mineral supplements for these patients.

Metabolizable energy values of diets supplemented with xylanase determined with laying hens

The objective of this study was to evaluate the effect of the supplementation of xylanase in diets with reduced energy level on the apparent metabolizable energy corrected for nitrogen, determined with laying hens at 14, 36, 60 and 80 weeks of age. Four digestibility trials were conducted, using 80 Hy-line W36 laying hens aged 14, 36, 60 and 80 weeks of age. Birds were distributed in a completely randomized design in 2 x 2 factorial arrangement (energy level x inclusion of xylanase), totaling four treatments with 10 replicates of two birds each. Treatments were: positive control (balanced diet for their age); positive control + xylanase; negative control (diet with reduction of 100 kcal/kg in the level of metabolizable energy); and negative control + xylanase. Xylanase, produced by microorganism Trichoderma reesei, was added to the diets at 100 g/t (16,000 BXU/kg) for diets fed at 14 weeks and 75 g/t for diets of 36, 60 and 80 weeks (12,000 BXU/kg). The data obtained were subjected to analysis of variance at 5% probability. Supplementation of xylanase promoted higher values for AME (apparent metabolizable energy) and AME(n) (apparent metabolizable energy corrected for nitrogen) determined with 80-week-old laying hens, subjected to diet with energy level according to the nutritional requirements for their age. Supplementation of xylanase increases the matabolizability coefficient of the dietary crude protein and improves the nitrogen retention of laying hens at 14 weeks. In addition, xylanase associated with adequate levels of dietary energy promotes higher values for AME and AME(n) determined with laying hens at 80 weeks of age.

Neutron activation analysis for assessing chemical composition of dry dog foods

Brazil holds the second largest population of domestic dogs in the world, with 33 million dogs, only behind the United States. The annual consumption of dog food in the country is 1.75 million tons, corresponding to the World's sixth in trade turnover. Dog food is supposed to be a complete and balanced diet, formulated with high quality ingredients. All nutrients and minerals required for an adequate nutrition of dogs are added to the formulation to ensure longevity and welfare. In this context, the present study aimed at assessing the chemical composition of dry dog foods commercialized in Brazil. Thirty-four samples were acquired in the local market of Piracicaba and analyzed by instrumental neutron activation analysis (INAA) to determine the elements As, Br, Ca, Co, Cr, Cs, Fe, K, La, Na, Rb, Sb, Sc, Se, U, and Zn. In general, the concentrations of Ca, Fe, K, Na, and Zn complied with the values required by the Association of American Feed Control Officials (AAFCO). To evaluate the safety of dog food commercialized in Brazil, further investigation is necessary to better understand the presence of toxic elements found in this study, i.e. Sb and U. INAA was useful for the screening analysis of different types and brands of dry dog foods for the determination of both essential and toxic elements.

Análisis de los efectos de un programa nutricional y de ejercicio físico sobre el perfil lipídico en personas con sobrepeso y obesidad

Introducción. Las enfermedades cardiovasculares (ECV) son la principal causa de muerte en nuestro país. Entre los factores independientes más importantes para el desarrollo de ECV se encuentran en primer lugar las alteraciones del perfil lipídico como el aumento del colesterol total (TC), las lipoproteínas de baja densidad (LDL) y los triglicéridos (TG) y/o la disminución de las lipoproteínas de alta densidad (HDL). Entre las diferentes formas de abordar el problema para prevenir y tratar estas patologías se encuentra la modificación de los hábitos de vida a través de un programa combinado de dieta y ejercicio. La evidencia confirma la efectividad de la primera variable, sin embargo, en el empleo del ejercicio se encuentran discrepancias acerca de cuál es el modo más eficaz para mejorar el perfil lipídico. Objetivo. Estudiar los cambios en las variables del perfil lipídico y los índices lipoproteicos comparando cuatro tipos de intervención que combinan dieta y diferentes modos de ejercicio, así como, analizar otras variables independientes (género, edad y genotipo ApoE) que pueden tener influencia sobre estos cambios. Diseño de la investigación. Los datos analizados en esta tesis forman parte del estudio “PROgramas de Nutrición y Actividad Física para el tratamiento de la obesidad” (PRONAF). Se trata de un estudio clínico desarrollado en España entre el 2008 y el 2011. La metodología del estudio nos permite comparar cuatro tipos de intervención para la pérdida de peso y evaluar su impacto sobre el perfil lipídico. El diseño fue experimental aleatorizado donde a todos los participantes se les sometió a un programa de dieta equilibrada hipocalórica junto a uno de los tres modos de ejercicio (grupo de entrenamiento de fuerza, grupo de entrenamiento de resistencia y grupo de entrenamiento combinado de los modos anteriores; los cuales fueron igualados en volumen e intensidad) o grupo de recomendaciones de actividad física. Las principales variables analizadas en los estudios que comprende esta tesis doctoral fueron: HDL, LDL, TG y TC, los índices derivados de estas y variables de la composición corporal y del entrenamiento. Conclusiones. Los cuatro tipos de intervención mostraron ser favorables para mejorar las variables del perfil lipídico y los índices lipoproteicos, sin diferencias significativas entre ellos. Tras la intervención, los varones mostraron una respuesta más favorable en los cambios del perfil lipídico. El genotipo ApoE2 obtuvo una reducción mayor en la concentración de TG y TC que el genotipo ApoE3 y ApoE4. Por último, los índices lipoproteicos mejoraron tras un programa de pérdida de peso, obteniéndose mayores cambios en el grupo de dieta más entrenamiento aeróbico para los índices ApoB/ApoA-1, TG/HDL y LDL/ApoB. ABSTRACT Introduction. The main cause of death in our country is cardiovascular disease (CVD). The most important independent factors for the development of CVD are the lipid profile alterations: increased total cholesterol (TC), low density lipoprotein (LDL) and triglycerides (TG) and/or decreased high-density lipoprotein (HDL). Among the different approaches to prevent and treat these diseases is modifying the lifestyle combining a diet and exercise program. The evidence confirms the effectiveness of the first variable, however, there is still controversy about the most effective mode of exercise combined with diet to achieve improvements. Objective. To study changes in lipoprotein profile comparing four types of intervention combining diet with different modes of exercise, and to analyze the independent variables (gender, age, and ApoE genotype) that can influence these changes. Research design. The data analized in this thesis are part of the study Nutrition and Physical Activity Programs for Obesity Treatments (the PRONAF study according to its Spanish initials). This is a clinical research carried out in Spain between 2008 and 2011. The aim of this study was to compare four types of intervention to weight loss with diet combining exercise. The design was experimental randomized where all participants were subjected to follow a hypocaloric balanced diet along one of the three modes of exercise (strength training group, resistance training group and combined training group of the above modes, which were matched by volume and intensity) or physical activity recommendations group. The main variables under investigation in this thesis were: HDL, LDL, TG and TC, the lipoprotein ratios, body composition and training variables. Main outcomes. The four types of interventions shown to be favorable to improve the lipid profile and lipoprotein level, with no significant differences between intervention groups. After the intervention, the men showed a more favorable respond in lipid profile changes. The genotype ApoE2 obtained more positive changes in the concentration of TG and TC than ApoE3 and ApoE4 genotype. Last, the lipoprotein ratios improve after weight loss treatment with diet combined different modes exercise. Our results reflected greater changes for E group in apoB/ApoA1, TG/HDL and LDL/ApoB compared within different intervention groups.

Contribution towards intelligent service management in wearable and ubiquitous devices

Hoy en día asistimos a un creciente interés por parte de la sociedad hacia el cuidado de la salud. Esta afirmación viene apoyada por dos realidades. Por una parte, el aumento de las prácticas saludables (actividad deportiva, cuidado de la alimentación, etc.). De igual manera, el auge de los dispositivos inteligentes (relojes, móviles o pulseras) capaces de medir distintos parámetros físicos como el pulso cardíaco, el ritmo respiratorio, la distancia recorrida, las calorías consumidas, etc. Combinando ambos factores (interés por el estado de salud y disponibilidad comercial de dispositivos inteligentes) están surgiendo multitud de aplicaciones capaces no solo de controlar el estado actual de salud, también de recomendar al usuario cambios de hábitos que lleven hacia una mejora en su condición física. En este contexto, los llamados dispositivos llevables (weareables) unidos al paradigma de Internet de las cosas (IoT, del inglés Internet of Things) permiten la aparición de nuevos nichos de mercado para aplicaciones que no solo se centran en la mejora de la condición física, ya que van más allá proponiendo soluciones para el cuidado de pacientes enfermos, la vigilancia de niños o ancianos, la defensa y la seguridad, la monitorización de agentes de riesgo (como bomberos o policías) y un largo etcétera de aplicaciones por llegar. El paradigma de IoT se puede desarrollar basándose en las existentes redes de sensores inalámbricos (WSN, del inglés Wireless Sensor Network). La conexión de los ya mencionados dispositivos llevables a estas redes puede facilitar la transición de nuevos usuarios hacia aplicaciones IoT. Pero uno de los problemas intrínsecos a estas redes es su heterogeneidad. En efecto, existen multitud de sistemas operativos, protocolos de comunicación, plataformas de desarrollo, soluciones propietarias, etc. El principal objetivo de esta tesis es realizar aportaciones significativas para solucionar no solo el problema de la heterogeneidad, sino también de dotar de mecanismos de seguridad suficientes para salvaguardad la integridad de los datos intercambiados en este tipo de aplicaciones. Algo de suma importancia ya que los datos médicos y biométricos de los usuarios están protegidos por leyes nacionales y comunitarias. Para lograr dichos objetivos, se comenzó con la realización de un completo estudio del estado del arte en tecnologías relacionadas con el marco de investigación (plataformas y estándares para WSNs e IoT, plataformas de implementación distribuidas, dispositivos llevables y sistemas operativos y lenguajes de programación). Este estudio sirvió para tomar decisiones de diseño fundamentadas en las tres contribuciones principales de esta tesis: un bus de servicios para dispositivos llevables (WDSB, Wearable Device Service Bus) basado en tecnologías ya existentes tales como ESB, WWBAN, WSN e IoT); un protocolo de comunicaciones inter-dominio para dispositivos llevables (WIDP, Wearable Inter-Domain communication Protocol) que integra en una misma solución protocolos capaces de ser implementados en dispositivos de bajas capacidades (como lo son los dispositivos llevables y los que forman parte de WSNs); y finalmente, la tercera contribución relevante es una propuesta de seguridad para WSN basada en la aplicación de dominios de confianza. Aunque las contribuciones aquí recogidas son de aplicación genérica, para su validación se utilizó un escenario concreto de aplicación: una solución para control de parámetros físicos en entornos deportivos, desarrollada dentro del proyecto europeo de investigación “LifeWear”. En este escenario se desplegaron todos los elementos necesarios para validar las contribuciones principales de esta tesis y, además, se realizó una aplicación para dispositivos móviles por parte de uno de los socios del proyecto (lo que contribuyó con una validación externa de la solución). En este escenario se usaron dispositivos llevables tales como un reloj inteligente, un teléfono móvil con sistema operativo Android y un medidor del ritmo cardíaco inalámbrico capaz de obtener distintos parámetros fisiológicos del deportista. Sobre este escenario se realizaron diversas pruebas de validación mediante las cuales se obtuvieron resultados satisfactorios. ABSTRACT Nowadays, society is shifting towards a growing interest and concern on health care. This phenomenon can be acknowledged by two facts: first, the increasing number of people practising some kind of healthy activity (sports, balanced diet, etc.). Secondly, the growing number of commercial wearable smart devices (smartwatches or bands) able to measure physiological parameters such as heart rate, breathing rate, distance or consumed calories. A large number of applications combining both facts are appearing. These applications are not only able to monitor the health status of the user, but also to provide recommendations about routines in order to improve the mentioned health status. In this context, wearable devices merged with the Internet of Things (IoT) paradigm enable the proliferation of new market segments for these health wearablebased applications. Furthermore, these applications can provide solutions for the elderly or baby care, in-hospital or in-home patient monitoring, security and defence fields or an unforeseen number of future applications. The introduced IoT paradigm can be developed with the usage of existing Wireless Sensor Networks (WSNs) by connecting the novel wearable devices to them. In this way, the migration of new users and actors to the IoT environment will be eased. However, a major issue appears in this environment: heterogeneity. In fact, there is a large number of operating systems, hardware platforms, communication and application protocols or programming languages, each of them with unique features. The main objective of this thesis is defining and implementing a solution for the intelligent service management in wearable and ubiquitous devices so as to solve the heterogeneity issues that are presented when dealing with interoperability and interconnectivity of devices and software of different nature. Additionally, a security schema based on trust domains is proposed as a solution to the privacy problems arising when private data (e.g., biomedical parameters or user identification) is broadcasted in a wireless network. The proposal has been made after a comprehensive state-of-the-art analysis, and includes the design of a Wearable Device Service Bus (WDSB) including the technologies collected in the requirement analysis (ESB, WWBAN, WSN and IoT). Applications are able to access the WSN services regardless of the platform and operating system where they are running. Besides, this proposal also includes the design of a Wearable Inter-Domain communication Protocols set (WIDP) which integrates lightweight protocols suitable to be used in low-capacities devices (REST, JSON, AMQP, CoAP, etc...). Furthermore, a security solution for service management based on a trustworthy domains model to deploy security services in WSNs has been designed. Although the proposal is a generic framework for applications based on services provided by wearable devices, an application scenario for testing purposes has been included. In this validation scenario it has been presented an autonomous physical condition performance system, based on a WSN, bringing the possibility to include several elements in an IoT scenario: a smartwatch, a physiological monitoring device and a smartphone. In summary, the general objective of this thesis is solving the heterogeneity and security challenges arising when developing applications for WSNs and wearable devices. As it has been presented in the thesis, the solution proposed has been successfully validated in a real scenario and the obtained results were satisfactory.

Qualidade nutricional de rações para cães: Influência de Zn na absorção de Cu e na prevenção de doença hepática

As rações comerciais devem ser um alimento balanceado que supra todas as exigências nutricionais nas diferentes fases da vida do animal. Sua formulação deve conter ingredientes de qualidade, em proporções adequadas. É de fundamental importância o conhecimento do valor nutricional das rações, para assegurar que o cão esteja ingerindo diariamente quantidades corretas dos nutrientes. O desbalanço de elementos essenciais e a presença de elementos tóxicos podem causar desequilíbrios nutricionais, doenças e, até mesmo, consequências fatais aos cães. O cobre é um dos vários elementos de importância a ser estudado quanto aos defeitos metabólicos nos cães. O acúmulo de cobre no fígado pode ocasionar lesões progressivas nas organelas dos hepatócitos, resultando em hepatite crônica e cirrose. Diante disso, este trabalho teve como objetivos (I) quantificação dos elementos químicos com função nutricional e com potencial tóxico presentes nas rações para cães adultos e filhotes, (II) avaliação da composição centesimal das rações amostradas, (III) avaliação da variação dos elementos químicos entre as amostras de ração de um mesmo lote de produção (IV), estudo da representatividade de pequenas porções-teste, (V) avaliação da bioacessibilidade de cobre em rações, com experimento in vitro. Os elementos químicos Al, As, Br, Ca, Cl, Co, Cr, Cs, Cu, Fe, I, K, La, Mg, Mn, Na, P, Rb, Sb, Sc, Se, Ti, U e Zn foram determinados pela análise por ativação neutrônica instrumental (INAA). A composição centesimal foi avaliada de acordo com os métodos recomendados da AOAC. A homogeneidade de distribuição dos elementos químicos nas rações foi avaliada pela análise de amostras grandes (LS-NAA). A bioacessibilidade de cobre nas rações foi estimada por meio da simulação da digestão gastrointestinal in vitro. Foi possível determinar por INAA todos os nutrientes minerais, isto é, Ca, P, K, Na, Cl, Mg, Fe, Cu, Mn, Zn, I e Se, com limites estabelecidos pela Association of American Feed Control Officials. Foram notadas em algumas rações altas concentrações de Al, Sb e U, elementos com grande potencial tóxico. Cerca de 16 % das amostras de ração apresentaram, pelo menos, um parâmetro não conforme quanto à composição centesimal. Os resultados obtidos por LS-NAA e NAA convencional mostraram variação na composição entre os sacos de ração para Br, Ca, Na e Zn, com boa concordância entre ambos os métodos. O emprego da LS-NAA combinada com NAA convencional permitiu observar que pequenas porções-teste (350 mg) de ração são representativas comparadas com aquelas de 1 kg para Br, Ca, K, Na e Zn. Em todas as rações para cães, 50 % do cobre presente estava sob a forma bioacessível

Análise nutricional de dietas publicadas em revistas não científicas destinadas ao público feminino

A procura do corpo ideal está fortemente ligada à perda de peso, sendo insistentemente abordada na comunicação social, a imagem corporal, têm conotações mais relacionadas com a moda do que com verdadeiros riscos para a saúde das pessoas. A sociedade atual cultiva a boa aparência física, "o conhecido estar em forma", associada a um ideal estético de magreza e, ao mesmo tempo, apela ao consumo de alimentos de elevada densidade calórica. Na busca do corpo ideal, as dietas de emagrecimento publicadas nas revistas poderão ser uma ajuda na concretização deste objetivo. É fácil encontrar em qualquer quiosque, papelaria ou supermercado estrategicamente colocadas, inúmeras revistas que atribuem à imagem corporal honras de primeira página. Na verdade, estas revistas não científicas divulgam dietas para todos os gostos e situações: dietas específicas para emagrecimento localizado, dietas de preparação para a praia ou para corrigir excessos cometidos em épocas festivas. Embora sabendo-se que estas “auto –dietas” constituem um dos métodos mais utilizados para a perda de peso corporal, não se sabe o número de seguidores que elas têm atualmente. Neste contexto, uma vez que a maior delas não contêm informação nutricional, é importante estar alerta para alguns problemas que podem resultar da ingestão recorrente e sem supervisão deste tipo de dietas. Neste âmbito e dada a pertinência do tema, constituiu objetivo principal do presente trabalho, a análise nutricional de dietas publicadas em revistas não científicas, destinadas ao público feminino em termos de macronutrientes e micronutrientes, sendo também considerado o número de refeições/dia e a variedade de alimentos recomendados. Assim, foram analisadas 15 dietas (497 refeições) publicadas em revistas destinadas ao público feminino, adquiridas entre o ano de 2009 e 2011. A conversão de alimentos em nutrientes foi feita através dos programas informáticos MedPoint e FatSecret. As dietas apresentaram valores energéticos totais (V.E.T.) médios diários, compreendidos entre 378,0 ± 53,8 Kcal e 2335,0 ± 135,0 Kcal. A avaliação dos macronutrientes revelou um teor proteico entre os 32,0 ± 3,6 % e os 12,0 ± 0,1% do total energético Os hidratos de carbono oscilaram entre 63,0 ± 0,1% e 43,0 ± 3,6%. Já a dieta mais rica em lípidos totais apresentava um valor médio de 32,0 ± 9,3% contra os 14,0 ± 0,1% do valor mais baixo encontrado. Nenhuma das dietas assegurava o valor recomendado de ingestão de fibra quando comparada com a dose diária recomendável (DDR). Relativamente à análise dos micronutrientes (vitamina D, vitamina E; vitamina C; vitamina B2, Ácido fólico, cálcio, fósforo, ferro, zinco), somente um tipo de dieta apresentou valores médios diários concordantes com as recomendações preconizadas. Considerando que as dietas analisadas tinham como objetivo a perda rápida de peso, estas revelaram-se maioritariamente hipocalóricas apresentando desequilíbrios e carências de determinados macronutrientes e micronutrientes que poderão, quando mantidas num período de tempo alargado ter consequências graves no desenvolvimento de carência ou outras patologias.

Exploring attitudes towards dietary modification and nutritional supplementation in people with and without age-related macular degeneration

Age-related macular degeneration (AMD) is the leading cause for visual impairment and blindness registration in the developed world. Due to the large amounts of conflicting AMD research on the role of nutrition and antioxidant intake, it is difficult for patients and practitioners to determine which measures can be taken to slow down the disease progression. The aim of this research was to determine the beliefs and knowledge that patients with AMD have about nutrition, to identify whether their condition is preventing them from eating a healthy diet, and to discover what their diet consists of. For the initial study, 158 participants with AMD (mean age 79 ± 7.8 years) and 50 participants without AMD (mean age 67 ± 8 years) were recruited from the Macular Society helpline, or from optometric practice. Participants had a 25 minute telephone interview where a 36-question survey was completed. The survey elicited demographic information, and questions covered the knowledge that participants had on nutrition and their current diet. The results from this survey uncovered three major findings: 1) 100% of AMD participants felt that they do not have enough information and support from eye-care practitioners regarding nutrition, 2) AMD patients are confused over, and display a lack of knowledge of, which foods are beneficial for eye health and when and what nutritional supplements to take, evidenced by 65% of participants not taking the correct dosage 3) AMD patients are not eating enough nutrients that would be beneficial for their condition - consuming an average of 1.4mg of lutein and zeaxanthin rather than the recommended 10mg. A clinical decision-making aid was created as an intervention based upon these findings. The aim of the aid was to help eye-care practitioners give the correct nutritional advice to their patients. Founded on the AREDS 2 inclusion and exclusion criteria, practitioners are able to identify which patients could benefit from a nutritional supplement, and which patients could benefit from dietary modification. An evaluation of the aid with 72 qualified eye-care practitioners exhibited a statistically significant increase in confidence after using the aid for two weeks. An evaluation using 51 student optometrists showed a statistically significant increase in confidence and a statistically significant increase in appropriate management of patients after using the aid. This project has elicited findings that are significant for AMD patient education. It is hoped that through these studies, patients will receive consistent advice about the risk factors for AMD, the link between AMD and nutrition, and the importance of maintaining a healthy, well-balanced diet.

RELIGIOSIDADE E ESTILO DE VIDA DE UMA POPULAÇÃO ADULTA

Objetivo: Caracterizar o perfil de religiosidade e estilo de vida de uma população adulta e analisar a associação entre essas variáveis. Métodos: Pesquisa descritiva, transversal e quantitativa, realizada com participantes (n=206) de duas Feiras de Saúde na cidade de São Paulo, em 20/10/2013 e 04/05/2014. Aplicaram-se dois instrumentos, o Duke University Religion Index (DUREL, subdividido nas dimensões Religiosidade Organizacional, Não Organizacional e Intrínseca) e o Estilo de Vida FANTÁSTICO. Realizaram-se os testes Rho de Spearman para associação das variáveis “estilo de vida” e “religiosidade”, e Qui- Quadrado para análise bivariada entre sexo e religiosidade. Resultados: Encontrou-se perfil de religiosidade predominantemente bom nas três dimensões, com destaque para a Religiosidade Intrínseca, que alcançou 83,5% (n=167) nos três quesitos. Quanto ao estilo de vida (FANTÁSTICO), obteve-se a classificação de: 26,6% (n=34) “Bom”, 48,4% (n=62) “Muito Bom” e 12,5% (n=16) “Excelente”. Das 125 análises bivariadas, 13 (11,3%) apresentaram correlação fraca (ρ< 0,30), porém significativa (p<0,05). Nas associações do Qui-Quadrado, a religiosidade se relacionou às dimensões do estilo de vida quanto ao uso de álcool e drogas, alimentação equilibrada e saúde mental. Conclusão: A religiosidade na população estudada, considerando-se as três dimensões analisadas, caracterizou-se como “boa” e “muito boa”; e o estilo de vida, segundo escore total do questionário FANTÁSTICO, pôde ser considerado saudável. Apesar de fraca, confirmou-se associação entre a religiosidade e o estilo de vida.
