Abstract

Neste número da Acta Portuguesa de Nutrição voltamos a dar conta da diversidade de temas de atualidade nas Ciências da Nutrição, uma diversidade que exige dos profissionais uma constante atualização relativa a conhecimentos e práticas. A desnutrição é certamente uma das temáticas que mais deve preocupar todos aqueles que se se importam com a saúde dos outros, individual e coletivamente. Embora o espectro da fome generalizada tenha, por ora, praticamente desaparecido das sociedades modernas e a sua lembrança seja já distante, deparamo-nos presentemente com um outro tipo de problema. A desnutrição presente em doentes internados em Hospitais constitui um fator de sério agravamento quer da sua condição clínica quer dos custos a suportar pela comunidade. O artigo de Santo Amaro e colaboradores, aqui publicado, dá exatamente conta da dimensão do problema num Hospital do Serviço Nacional de Saúde e revela números preocupantes e que incidem particularmente na população idosa doente, sendo que os dados da desnutrição no momento de admissão ao Hospital se revelam especialmente graves.

Fica assim evidente que não só é fundamental a implementação universal das ferramentas de rastreio da desnutrição na admissão hospitalar como é absolutamente necessário um melhor acompanhamento destas pessoas na comunidade.

Numa sociedade de abundância e em que os problemas que a sociedade normalmente associa à má alimentação são aqueles que resultam do excesso, o caminho do reconhecimento da desnutrição como importantíssimo fator de agravamento do estado de saúde de muitos indivíduos é certamente difícil. Cabe à comunidade científica e profissional esta tarefa, pois acreditamos que sem o reconhecimento geral dificilmente se poderá atenuar o problema de forma significativa. O direito à alimentação adequada é universal e válido para jovens e idosos, saudáveis e doentes: faça-se pois da boa prática um instrumento de igualdade e justiça.

Estado nutricional e risco de doença de Alzheimer

Nutritional status and risk of Alzheimer’s disease
Maria Janaina Bernarda da Silva; Marcela Paloro; Mike Yoshio Hamasaki;
Abstract

ABSTRACT

Alzheimer’s disease is a neurodegenerative disorder characterized by deposits of extracellular amyloid-beta peptides and intracellular neurofibrillary tangles. In symptomalogical terms, alterations of cognitive functions are the most frequently encountered conditions in individuals with Alzheimer’s disease, dementia being the main one. Amongst the diverse risk factors for Alzheimer’s disease, age is widely recognized as the principal one. According to the American, Brazilian, British and Canadian Alzheimer’s associations, environmental factors of risk, associated with lifestyle, are equally important for the development of Alzheimer’s disease. These above-mentioned Alzheimer’s associations and several scientific articles suggest that obesity is among the factors associated with lifestyle that may increase the incidence of this disease. Nonetheless, a recently published study points to conflicting results as to the true role of obesity in promoting it. Taking into account the clash of opinions present in scientific literature on the influence of obesity and malnutrition on the genesis of dementia, this scientific paper aims to speculatively investigate physiopathological aspects which confirm whether obesity or malnutrition may or may not be considered risk factors for Alzheimer’s disease.

Abstract

ABSTRACT

Introduction: Obesity is one of the more serious health problems worldwide. Finding solutions to the designated epidemic of the twenty-first century persists, and the relationship between the consumption of sweetened beverages and body weight became a relevant issue.

Objectives: To evaluate the impact of an awareness strategy about the content of simple sugars present on a range of drinks available in the cafeteria.

Methodology: The sales of a range of beverages were analyzed, before and after intervention. The intervention was based on the exposure of a framework with drinks and the representation of the amount of simple sugars, in sugar, under the motto “The sugar that you eat when you drink”. An analysis of proportion of sales, with a confidence interval of 95% was performed.

Results: After statistical analysis of the ratios was observed a statistically significant reduction in the number of units sold of soft drinks, coca-cola and carbonated drinks. In addition, there was an increase in the number of units sold, with statistical significance, of fruit nectars, tea / infusions and chocolate milk.

Conclusions: The intervention in the cafeteria of the Escola de Hotelaria e Turismo de Coimbra was successful with an effective reduction in sales of sweetened beverages.

Alimentos com e sem glúten – análise comparativa de preços de mercado

Gluten and Gluten-Free Products – Price Difference
Daniela Afonso; Rita Jorge; Ana Catarina Moreira;
Abstract

ABSTRACT

Celiac disease is an autoimmune chronic disease characterized by gluten sensitivity, which manifests in genetically susceptible individuals. When people with celiac disease consume gluten, their body mounts an immune response that attacks the small intestine. Being so, the only known treatment for celiac disease is a lifelong strict gluten-free diet that should be complete, balanced and varied.

The objetives of these study were compare prices between categories of gluten-free products and equivalents with gluten, assess costs in a family income of a gluten-free diet and compare the results with a previous study.

The price per kilogram of gluten and gluten-free products was collected through online search. Prices were analyzed by product type, among seven categories (bread, pasta, flour, breakfast cereals, cookies/ cakes, cereal bars and ready meals) of all gluten-free products, and the same prices of equivalents gluten products were collected. The food prices included in the essential food basket with gluten, developed by Portuguese nutritionists association, were posteriorly adjusted to the gluten-free diet.

In all categories of products analyzed gluten-free products were more expensive. Largest differences were observed in food categories such as pasta, bread and cookies categories. It was found a difference of 26% in prices when comparing gluten-free essential food basket and the gluten equivalent. The added cost for a family to follow a gluten-free diet for one month is 110€ and weekly per person is 8,6€.

The present study demonstrates that, in all categories, gluten-free products studied are more expensive than equivalents gluten products. The price of the gluten-free essential food basket is greater than the equivalent with gluten, it represents more than a half of a family budget, of national minimum salary. Compared to a previous study the difference between prices of gluten-free and gluten products decreased in most categories.

Avaliação do risco de desnutrição num serviço de Medicina do Hospital Distrital de Santarém (Medicina IV)

Evaluation of risk of malnutrition in the “Medicine IV” service of Hospital Distrital de Santarém

Abstract

ABSTRACT

Malnutrition is a common health issue during hospitalization.

This article present the results of a descriptive and observational study from patients hospitalized in the “Medicina IV” service at of Hospital Distrital de Santarém, completed with the purpose of identifying the degree of malnutrition risk and measure the patients nutritional evolution as well the sources of the same parameter, in order to measure if there is any significant difference in prevalence. 150 individuals were measured with an average of 80 years of both sexes, an anthropometry evaluation was realized by indirect (estimated weight and height) and direct methods (height knee, calf and arm circumferences) to calculate body mass index, one of the parameters needed to determine the risk of malnutrition. Upon hospital admission, it was identified by the Malnutrition Universal Screening Tool (MUST), 29.3 % (N = 44) of patients with high risk of malnutrition and 70.7 % (N = 106) with high risk of malnutrition.

In conclusion, the rate of malnutrition in hospitalized patients is high, which can compromise the clinical outcomes. In this context, it is essential the frequent nutritional assessment of hospitalized patients, allowing for an early identification and nutritional intervention.
