Determinação do perfil dos usuários e da composição química e nutricional da alimentação oferecida no restaurante universitário da Universidade Estadual Paulista, Araraquara, Brasil

Este estudo teve como objetivos determinar o perfil e o estado nutricional da clientela e a composição química e nutricional das refeições oferecidas no restaurante universitário da Universidade Estadual Paulista de Araraquara, Brasil. Realizou-se a determinação química do teor de proteínas, lipídios, carboidratos, fibra, cinzas e umidade de amostras das refeições fornecidas. A amostra populacional foi constituída de 403 usuários (212 mulheres e 191 homens). em relação ao perfil do usuário, constatou-se que 82,60% encontravam-se na faixa etária de 18 a 25 anos e 75,44% dos indivíduos apresentaram índice de massa corporal dentro da faixa de normalidade. em média, as refeições continham 4,74% de proteínas, 10,84% de lipídeos, 24,32% de carboidratos, 3,30% de fibras, 1,00% de cinzas e 55,00% de umidade. Os dados mostraram que as refeições do restaurante universitário continham excesso de proteínas e de energia e que se faz necessário realizar ajustes na sua composição para adequá-la ao perfil da clientela atendida.

Nutritional intake according to injury extent in ulcerative colitis patients

Background: Ulcerative colitis (UC) is often associated with nutritional deficiency, which appears to contribute to the progression of UC severity. The present study aimed to evaluate nutritional status and dietary intake in UC remission patients. Methods: The present study comprised a cross-sectional study in which variables such as extent of disease (distal colitis, left-sided colitis, pancolitis), remission period, sex and age were recorded. Extent of disease was assessed by the results of a colonoscopy and dietary intake was evaluated by using 3-day, 24-h recalls. A Kruskall-Wallis test was used to compare the intake of macro- and micronutrients among the three study groups. The analysis was complemented by the Mann-Whitney test. A logistic regression analysis was performed to identify predictive factors of extent of disease (pancolitis versus left-sided colitis versus distal colitis). Results: The median (range) age of the 59 patients was 49.0 (37.0-63.0) years and 53.3% were female. Twenty-six (44.1%) patients had distal colitis, 11 (18.6%) patients had left-sided colitis and 22 (37.3%) patients had pancolitis. A high probability of an inadequate intake of fibre (100%), fat soluble vitamins (>40% for vitamin A and >95% for vitamin E), vitamin C (>34%), calcium (>90%) and magnesium (>50%) was identified in the study group. Vitamin D intake (odds ratio = 0.60; 95% confidence interval = 0.39-0.94; P < 0.05) was significantly associated with increased intestinal damage. Conclusions: A large number of individuals showed an inadequate intake of nutrients. In addition, the consumption of vitamin D was significantly associated with extent of disease. © 2013 The British Dietetic Association Ltd.

Protein-energy malnutrition as a consequence of the hospitalization of gastroenterologic patients

The effects of the clinical and dietetics in patient managements on the protein-energy status of hospitalized patients were retrospectively (four yr) investigated in 243 adult (49 +/- 16 yr), male (168) and female (75) patients suffering from chronic liver diseases (42%), intestinal diseases with diarrhea (14%), digestive cancers (11%), chronic pancreatitis (10%), stomach and duodenum diseases (7%), acute pancreatitis (7%), primary protein-energy malnutrition (3%), esophagus diseases (3%), intestinal diseases with constipation 14 (2%) and chronic alcoholism (2%). The protein-energy nutritional status assessed by combinations of anthropometric and blood parameters showed 75% of protein energy malnutrition at the hospital entry mostly (4/5) in severe and moderate grades. The overall average of hospitalization was 20 +/- 15 days being the shortest (13 +/- 5,7 days) for esophagus diseases and the longest (28 +/- 21 days) for the intestinal diseases with diarrhea patients which also received mostly (42%) of the enteral and/or parenteral feedings followed by acute pacreatitis (41%) and digestive cancers (31%) patients. When compared to the entry the protein-energy malnutrition rate at the discharge decreased only 5% despite the increasing of 30% found on the protein-energy intake. The main improvement of the protein-energy nutritional status were attained to those patients showing protein-energy malnutrition milder degrees at the entry which belonged mostly to primary protein-energy malnutrition, acute pancreatitis and intestinal diseases with diarrhea diseases. The later two groups showed protein-energy nutritional status improvement only after the second week of hospitalization. The digestive cancers patients had their protein-energy nutritional status worsened throughout the hospitalization whereas it happened only in the first week for the intestinal diseases with diarrhea and chronic liver diseases patients, improving thereafter up to the discharge. The protein-energy nutritional status improvement found in few patients could be attributed to some complementary factors such as theirs mild degree of protein-energy malnutrition at entry and/or non-invasive propedeutics and/or enteral-parenteral feddings and/or longer hospitalization staying. The institutional causes for the unexpected lack of nutritional responses by the patients were probably the high demand for the few available beds which favour the hospitalization of the most severed patients and the university-teaching pressure for the high rotation of the available beds. Both often resulting in early discharging. In persisting the current physical area and attendance demand one could suggest an aggressive support early at the entry preceding and/or accompanying the more invasive propedeutical procedures.
