A respiração oral em crianças e suas repercussões no estado nutricional

PURPOSE: identify nutritional state, masticatory function, respiratory mode, sense of smell and sense of taste among mouth breathing children. METHODS: nasal aeration, mastication, nutritional state of 77 mouth breathing children and 154 nasal breathers children between six and ten years were evaluated. RESULTS: mouth breathers exhibited alterations in the masticatory pattern when compared to the nasal-breathers, but did not have statistical significance in nutritional state. CONCLUSION: the oral-breathing children had more alteration in sleep, reduction in the ingestion of carbohydrate and increase in ingestion of lipids, however, no consistent data were found pointing out the association between mouth breathing and nutritional condition.

Effects of different concentrations of sugarcane alcohol on food intake and nutritional status of male and female periadolescent rats.

The present study evaluated the effects of food and alcohol intake on the nutritional and metabolic status of male and female periadolescent rats submitted to single (15%) and multiple (10%, 20%, 30%) concentrations of hydroalcoholic solutions of sugar-based alcohol associated with a feed mixture. Thirty-six periadolescent Wistar rats were used and randomly arranged into three groups: Group A (control; 0% ethanol; six males and six females), Group B (15% ethanol; six males and six females), and Group C (10%, 20%, and 30% ethanol; six males and six females). Food consumption, body weight, water intake (mL), ethanol intake (g/kg/day), ethanol preference in relation to water and different concentrations, and serum biochemical dosages (glucose, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol, very low-density lipoprotein fraction, triglycerides, cholesterol/HDL [CT/HDL], albumin) were analyzed. Males from Group C ingested more feed than females, which consumed reducing amounts throughout the weeks studied. Males also had heavier body weight, which increased throughout the experimental period. The animals ingested more water (females ingested more than males) in the first experimental week. Group C had a higher ethanol intake and greater preference for ethanol over water in both genders than Group B, which decreased over the subsequent weeks. Serum glucose was lower in Group A, whereas the CT/HDL ratio was lower in Group C. These findings allow the conclusion that nutritional and metabolic impact resulting from alcohol intake is different between genders and between the different forms in which the drug is offered. It is important to warn the population about the concentrations of alcohol intake, which may influence the growth and development of adolescents, thereby compromising their quality of life.

Valor nutricional de dietas veiculadas em revistas não científicas - doi: 10.5020/18061230.2010.p349

Objective: To assess the nutritional value of weight-loss diets disclosed in non-scientific magazines. Methods: A quantitative cross-sectional study carried out in two phases (first investigation in 2007; second investigation in 2009), in which 120 weight-loss diets were randomly selected from 24 magazines divided into three groups based on cost. The menus were evaluated with regard to calories, macronutrients and fiber, using the Diet Pro 2 program. The SPSS program (version 15.0) was used for statistical analysis, with the results expressed as mean, standard deviation and confidence intervals. Two-way analysis of variance (ANOVA) with Tukey’s paired post hoc comparison was used for the quantitative study of the nutrients in each group of magazines and each phase of the study. The Student’s t-test was used for the comparisons of mean values obtained with the diets and established recommendations. The level of significance was set at 5.0%. Results: The energy supply was higher in 2007. Over time, mean protein content in the diets diminished, lipid content remained similar and glucose content increased. Based on the recommended values, the diets were characterized as hypoglycemic, high-protein and normolipidemic. The content of micronutrients was lower than recommended amounts in both years assessed. The fiber content increased in the second year in relation to the first, but did not reach the recommended level. Conclusion: Diets showed inadequacies of macro and micronutrients in the two studied years, with an imbalance between their components.
