Alimentação e estado nutricional de grupos da população do concelho de Lisboa

RESUMO - Objectivo: descrever o estado nutricional e o padrão alimentar de grupos da população de Lisboa. Delineamento, locais e participantes: estudo transversal do estado nutricional e do padrão alimentar de homens com 38 anos e mulheres e homens com 50-65 anos que vivem na freguesia do Lumiar, do concelho de Lisboa; estudo transversal dos hábitos alimentares e do estado nutricional de adolescentes com 12 a 19 anos estudantes de escolas secundárias de Lisboa; estudo transversal da excreção de sódio em urina de 24 horas de rapazes de 7 a 8 anos de escolas primárias do Lumiar. Métodos: o estado nutricional foi avaliado com metodologias padronizadas tal como propostas pela OMS. A ingestão alimentar foi medida pelo método das 24 horas anteriores no primeiro estudo e pelo método da história alimentar no segundo estudo. Resultados: nas crianças, a excreção urinária de sódio foi uma das mais altas da Europa. Nos adolescentes, a prevalência de excesso de peso/obesidade foi de 19% nos rapazes e 16% nas raparigas. 16% dos adolescentes não tomam pequeno-almoço, mas mais de 30% comem bolos a meio da manhã. A proporção de adolescentes com uma ingestão diária de certos alimentos é de 44% para guloseimas, 43% para bolos, 29% para refrigerantes e 16% para chocolates e gelados. Por outro lado, a frequência de ingestão diária de fruta e produtos hortícolas é baixa, principalmente nos adolescentes de menor nível sócio-económico. Nos adultos, 57% dos homens com 38 anos e 80% e 74% dos homens e mulheres com 50-65 anos, respectivamente, têm excesso de peso ou obesidade. A hipertensão arterial foi detectada em mais de 20% dos homens jovens e a sua prevalência aumenta com a idade. Foi observado um colesterol sérico superior a 200 mg/dL em perto de metade dos adultos e maior do que 240 mg/dL em 28% dos homens com 38 anos, em 24% dos homens com 50-65 anos e 44% das mulheres do mesmo grupo etário. 20% dos adultos jovens têm colesterol HDL inferior a 35 mg/dL, mais do que um terço são fumadores e a ingestão de álcool representa 13% da sua ingestão calórica total. Conclusões: foram observados estilos de vida não saudáveis, nomeadamente padrões alimentares não equilibrados, uma elevada prevalência de obesidade, hipertensão e dislipidemias, e, por isso, uma percentagem relativamente elevada da população de Lisboa tem um risco elevado de doenças cárdio-vasculares e outras doenças crónicas, bem como de morte prematura.

Hypertensives' Knowledge About High-Sodium Foods and Their Behavior

Abstract Background: In Brazil, the prevalence of systemic arterial hypertension (SAH) is approximately 30% of the total population. In 2010, SAH was the cause of death of about 9.4 million people worldwide. A healthy dietary pattern is important to maintain proper blood pressure levels and, consequently, disease control. Objectives: To describe the knowledge and practices of hypertensive patients cared for at a public hypertension outpatient clinic, and its relationship with high-sodium food. Methods: We applied a questionnaire to patients with questions related to sociodemographics, dietary pattern, frequency of ingestion of certain foods, and knowledge about their own disease. Results: We studied 221 patients, 56.1% of whom were women, and 53.8% had only elementary education. Their mean age was 57.7 ±13.5 years, and 75.6% of them reported having high blood pressure, and 11.3%, diabetes mellitus. Regarding dietary pattern, 62% used ready-to-use seasonings, but 94.1% reported not adding extra salt to their ready meals. Regarding patients' knowledge about high-sodium foods and SAH, only 8 patients had 100% of right answers, 37 patients had 73.8%, and 42 patients, 57% of right answers. Conclusion: Knowledge about SAH prevention and high-sodium foods was insufficient. Based on this study's findings, more effective educational strategies targeted at this population can be developed.

Novo gênero de nematóide do solo da família Actinolaimidae

Caryboca paranaensis n.g., n.sp. (Nemata, Actinolaimidae) was found inhabiting soil around coffee roots sent in from Cornélio Procópio, State of Paraná, Brazil. Definition of the new genus: Actinolaimidae, Actinolaiminae. Lip region distinctly offset by a constriction and showing a cuticularized basket-like structure provided with lateral denticles and two rather strong teeth pointing forwards. Cuticular rod-like thickenings extending back from the basket-like structure to the guiding-ring. Anterior part of oesophagus a non-muscular, narrow tube; posterior part wider and provided with strongly developed radial musculature. Gonads paired and reflexed. Tail attenuated, pointed. Males and food habits unknown. Caryboca n.g. differs from Actinolaimus Cobb, 1913, by having a labial basket-like structure as well as by the non-muscular nature of the anterior part of oesophagus. Caryboca n.g. differs from Carcharolaimus Thome, 1939, by having two strong pharingeal teeth and pointed tail.

Trophic ecology of Lontra longicaudis (Carnivora, Mustelidae) in lotic and semilotic environments in southeastern Brazil

Lontra longicaudis (Olfers, 1818) (Carnivora, Mustelidae) is a semi-aquatic animal spread through the Central and South America, except in Chile. The implantation of a hydroelectric power plant along a river alters the dynamics of the watercourse, transforming a lotic environment into a lentic or semilotic one, what can damage the otter's feeding. From April 2008 to March 2009 we analysed the otter's food habits in lotic (streamlet) and semilotic (hydroelectric reservoir) environments of Paranapanema Valley, in southeastern Brazil. Aiming to compare the otter's diet of these two environments, we analyzed statistically the frequency of occurrence of main items in the scats. Fishes represent the base of the diet both in the reservoir and in the streamlet and, despite of the total otter's diet showing up similarities in the two environments, the results evidenced modifications on the fish species consumed between them. In the reservoir the otters ate more exotic fish Oreochromis niloticus (Linnaeus, 1758) probably because it is an easy capture prey in this place. The fact that the otters get established and feed in the reservoir doesn't mean that this structure is benefic to the species because the food supplied for it consists mainly of exotic fish species.

The diet of the South American sea lion (Otaria flavescens) at Río Negro, Patagonia, Argentina, during the winter-spring period

The South American sea lion, Otaria flavescens (Shaw, 1800) population is steadily expanding along the Patagonian coast of Argentina in the last decades. However, little is known about the feeding ecology of the species in the area. The aim of this study was to analyze the food habits of O. flavescens from 91 scats collected at Río Negro province, during the winter and spring of 2005. Fish occurred in 96% of scats containing prey remains, followed by cephalopods (26%). Raneya brasiliensis (Kaup, 1856) was the most frequent and abundant species occurring in 58.6% of samples and constituting almost 50% of fish predated. Second in importance were Porichthys porosissimus (Cuvier, 1829) and Cynoscion guatucupa (Cuvier, 1830) in terms of occurrence (%FO 20.7) and numbers (29.6%) respectively. The squid Loligo gahi (d'Orbigny, 1835) was the most frequent cephalopod prey (42.1%), whereas Octopus tehuelchus (d'Orbigny, 1834) was the most abundant (77%). The higher amount and diversity of prey found in the spring in comparison with the winter season might be related to a higher feeding activity of seals or to a seasonal increase in food availability in the area.

Determinació de diferents compostos bioactius en ingredients naturals per a l'elaboració de bombons funcionals amb beneficis cardiovasculars

Durant les darreres dècades, i degut, principalment, a un canvi en els hàbits alimentaris, hi ha hagut un augment a nivell mundial de malalties cròniques (l’obesitat, malalties cardiovasculars, etc.). En els països mediterranis hi ha menys incidència d’aquestes malalties i sembla ser que això es deu a l’anomenada dieta mediterrània. La dieta mediterrània es caracteritza per una combinació d’oli d’oliva com a grassa principal, verdures, hortalisses i fruites en abundància, lleguminoses, fruits secs, formatges i iogurt, peix, pa, pasta, cereals i els seus derivats i un consum moderat de vi i carns. Aquest model alimentari, ric en tocoferols, fitosterols i fitoestanols que ajuden a reduir el contingut de colesterol en sang, fa que en les poblacions mediterrànies hi hagi menys incidència de malalties cardiovasculars. Aquests compostos inhibeixen el deteriorament oxidatiu dels olis, actuen com agent antipolimerització per olis de fregir. Tenen capacitat de reduir els nivells de colesterol, evitant la incidència de malalties cardiovasculars. Els fitoesterols y fitoestanols es poden trobar en forma lliure o esterificada amb àcids grassos, àcids fenòlics i glucosa. Els objectius d’ aquest treball han estat, primer en el desenvolupament de mètodes d'anàlisi ràpids, fiables i robusts dels tocoferols, fitoesterols i fitoestanols i la seva aplicació en fruits sec, oli de segó, oli de pinyol de raïm i productes que els continguin. El primer mètode va estar basat en la cromatografía líquida (HPLC-DAD) amb extracció en fase sòlida (SPE) com tècnica alternativa a la saponificació para la determinació de fitoesterols lliures. Aquest mètode va estar aplicada a mostres de bombons que contenia fitoesterols. El segon mètode va estar basat en la cromatografia de gasos (GCFID) amb aponificació i SPE per quantificar fitoesterols i fitoestanols lliures, esterificats i totals. En els documents annexos es descriuen a profunditat els mètodes desenvolupats.

Estudi epidemiològic de l'obesitat de 1r d'ESO de l'IES Pedraforca

Treball de recerca realitzat per una alumna d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l'any 2009. L'obesitat és una malaltia crònica que es caracteritza per un augment de la massa grassa i en conseqüència per un augment de pes. En el segle XXI aquesta malaltia, considerada epidèmia, està arribant a la població infantil i adolescent, i ha cridat l'atenció de totes les institucions de salut pública que estan lluitant per evitar aquesta alta prevalença d'obesitat i sobrepès. Aquest estudi confirma que existeix un alt percentatge d'obesitat i sobrepès en l'edat infantil i que està relacionat amb factors de risc (alguns modificables) que poden ser clau per a evitar aquesta malaltia. El mètode emprat és la realització d’un estudi epidemiològic transversal sobre una mostra de nens compresa en 39 individus de 12 a 14 anys d'edat. Es van determinar el pes, la talla, el plec bicipital i tricipital, l'ample del canell i del colze, a més de la realització d'una enquesta sobre hàbits alimentaris en l’esmorzar i dades socioculturals. L'obesitat i el sobrepès es van definir com resultats de IMC iguals als percentils 85 i 97 de les taules Orbegozo, respectivament. Els resultats van mostrar una prevalença de sobrepès i obesitat en la nostra mostra de població que va ser de 28,2%, la de només sobrepes del 15,4% i la de només obesitat del 12,8%. La prevalença d'obesitat és major en nens amb un 13,6% que en nenes 12,5% igual que el sobrepès. L'obesitat i sobrepès és major quan els estudis materns són inferiors als universitaris, també quan existeixen famílies amb 3 o més fills i quan es veu la TV més de 3 hores al dia.

Diet diversity and the risk of laryngeal cancer: a case-control study from Italy and Switzerland.

Diet diversity (defined as the number of different foods consumed) has been considered an indicator of a healthy diet, and favorably related to the risk of several digestive tract cancers. We analyzed the relation between diet diversity and the risk of laryngeal cancer using data from a case-control study carried out between 1992 and 2000 in Italy and Switzerland. The subjects of the study were 527 patients with histologically confirmed incident cancers of the larynx and 1297 patients admitted for acute, non-neoplastic diseases, unrelated to tobacco or alcohol consumption. Total diversity was computed as the number of different foods (overall and within four food groups, i.e., vegetables, fruit, meat, and cereals) consumed at least once per week. A significant inverse association was observed for vegetable diversity (OR=0.41, 95% CI: 0.28-0.59, for the highest versus the lowest quartile) and fruit diversity (OR=0.40, 95% CI: 0.27-0.59). Conversely, a direct association was found for meat diversity (OR=1.67, 95% CI: 1.11-2.50), while no meaningful association was found for total diet and cereal diversity. The results were consistent across strata of age, alcohol drinking and tobacco smoking. This study suggests that a diet not only rich but also varied in fruit and vegetables is related to a decreased risk of laryngeal cancer risk.

Healthy lunchboxes

Good food habits set early in childhood can last a lifetime. Lunches provide around one third of our daily nutritional needs, so it’s important to put some thought and planning into them. Here are some tips on how to prepare a healthy lunchbox. Sevensteps to creatinghealthy, varied and interestinglunchboxes Include a wide variety of foods - starchy foods, protein, dairy, and fruit and vegetables Try to offer different foods every day - no one wants to be eating a ham sandwich five days a week! Vary the types of bread e.g. pitta bread, bagels, wholemeal rolls - - keep a stock in the freezer Cook extra rice/pasta in the evening - these can make interesting salads Theme your lunchbox on a different country, e.g. Italian - try a pasta salad, Mexican fill flour tortillas Home-made soup (in a Thermos flask) is great for cold days, while salads are light and refreshing for warmer weather. Both are packed with essential vitamins and minerals Fluids are important for children - up to 6 cups of fluid should be encouraged daily. Milk and water are the best options. Straws and brightly coloured drinks bottles can make rehydrating more interesting!

Weight Reduction Service

The aim of this intervention is to offer support to overweight and obese patients, particularly those with co-morbidities to make changes to lifestyle in food habits and physical activity.

Sugar Reduction: Responding to the Challenge

In ‘Sugar Reduction: Responding to the Challenge’, PHE is calling on charities, non-governmental organisations (NGOs), academics, businesses, retailers and consumers to work together to reduce the amount of sugar we eat as a nation. By analysing dietary data and discussing food habits with stakeholders, we have identified a range of areas that need exploring further. PHE already runs successful marketing campaigns designed to promote healthy living. To build on this, we also want to look at the way foods are being advertised to children, financial measures that relate to sugar sweetened drinks, food procurement across the public sector and education and training. Today, PHE received a draft report from the Scientific Advisory Committee on Nutrition (SACN): ‘Carbohydrates and Health’. PHE is particularly interested in SACN’s research because it is clear that the nation is consuming more sugar than the UK’s current recommendations. Diets high in sugar can contribute to excess calorie intake, which can lead to weight gain and obesity.

Obesity prevention opinions of school stakeholders: a qualitative study.

BACKGROUND: In general, schools are an important setting to implement current recommendations for obesity prevention in children because the vast majority of children attend school. This study investigated the opinions of different school stakeholders on the feasibility and acceptability of current obesity prevention strategies that could be implemented in Swiss schools. METHODS: Research methods were comprised of a qualitative study which included school directors, physical education teachers, catering staff, school nurses and health educators, parents of young adolescents, and young adolescents interviewed (N = 40) categorized into 6 focus groups. Open-ended questions were used to determine the participants' opinion regarding current obesity prevention recommendations, and healthy eating and physical activity promotion strategies. RESULTS: All participants approved the implementation of nutritional standards for food and drinks sold in schools, but thought that increasing the attractiveness of healthy options was the best strategy to improve eating habits. Enjoying participation in physical activity classes or after-school activities was stressed. Participants suggested offering classes for all students with poor physical condition, independent of weight status. Stakeholders called for governmental support and global coordination of interventions balanced with providing schools with enough autonomy to adapt programs relevant to their individual circumstances. They recommended integrating all school stakeholders in obesity prevention initiatives, with special attention to students and local authorities. CONCLUSIONS: Participants agreed that schools are a crucial setting to implement childhood obesity prevention strategies. They called on school stakeholders to join efforts aiming to encourage healthy behaviors and to support and reinforce parents' efforts by spreading consistent and coherent health messages.

Concentrations of resveratrol and derivatives in foods and estimation of dietary intake in a Spanish population: European Prospective Investigation into Cancer and Nutrition (EPIC)-Spain cohort

Resveratrol has been shown to have beneficial effects on diseases related to oxidant and/or inflammatory processes and extends the lifespan of simple organisms including rodents. The objective of the present study was to estimate the dietary intake of resveratrol and piceid (R&P) present in foods, and to identify the principal dietary sources of these compounds in the Spanish adult population. For this purpose, a food composition database (FCDB) of R&P in Spanish foods was compiled. The study included 40 685 subjects aged 35–64 years from northern and southern regions of Spain who were included in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Spain cohort. Usual food intake was assessed by personal interviews using a computerised version of a validated diet history method. An FCDB with 160 items was compiled. The estimated median and mean of R&P intake were 100 and 933 μg/d respectively. Approximately, 32 % of the population did not consume R&P. The most abundant of the four stilbenes studied was trans-piceid (53·6 %), followed by trans-resveratrol (20·9 %), cis-piceid (19·3 %) and cis-resveratrol (6·2 %). The most important source of R&P was wines (98·4 %) and grape and grape juices (1·6 %), whereas peanuts, pistachios and berries contributed to less than 0·01 %. For this reason the pattern of intake of R&P was similar to the wine pattern. This is the first time that R&P intake has been estimated in a Mediterranean country.
