title: Preferences for menu labelling formats of young adults in Brazil and in the United Kingdom

description: ABSTRACT Objective This pilot study was aimed at exploring preferences of young adults in two different contexts on restaurant menu labelling formats. Methods Five focus groups were conducted with 36 participants, two focus groups with 11 participants in Brazil and three focus groups with 25 in the United Kingdom. Themes originating from the content analysis of the transcriptions were organised around four possible menu labelling formats: 1) numerical information on calories; 2) numerical information on calories and nutrients; 3) traffic light system plus Guideline Daily Amounts; 4) food information with ingredients list plus highlighted symbols. Results In both countries, participants preferred the ingredients list plus symbols format, considered more comprehensive and useful to make an informed food choice. Organic food and vegetarian symbols were the ones considered most important to appear on restaurant menu labels with ingredients list. However, most participants in Brazil and in the United Kingdom rejected the information restricted to calories and calories plus nutrients formats, saying that these would not influence their own choices. Conclusion This is the first multicultural qualitative study exploring preferences of people living in different countries with different eating habits, but where menu labelling is voluntary. Results evidenced similarities in participants’ likes and dislikes for menu labelling formats in these two different contexts. Discussions showed participants in both countries prefer qualitative information than numerical information, suggesting that ingredients list and symbols provide information that people want to see on the menu.

title: Internal consistency and content validity of a questionnaire aimed to assess the stages of behavioral lifestyle changes in Colombian schoolchildren: The Fuprecol study

description: ABSTRACT Objective To assess internal consistency and content validity of a questionnaire aimed to assess the stages of Behavioural Lifestyle Changes in a sample of school-aged children and adolescents aged 9 to 17 years-old. Methods This validation study involved 675 schoolchildren from three official school in the city of Bogota, Colombia. A self-administered questionnaire called Behavioural Lifestyle Changes has been designed to explore stages of change regarding to physical activity/exercise, fruit and vegetable consumption, alcohol abuse, tobacco use, and drug abuse. Cronbach-α, Kappa index and exploratory factor analysis were used for evaluating the internal consistency and validity of content, respectively. Results The study population consisted of 51.1% males and the participants’ average age was 12.7±2.4 years-old. Behavioural Lifestyle Changes scored 0.720 (range 0.691 to 0.730) on the Cronbach α and intra-observer reproducibility was good (Kappa=0.71). Exploratory factor analysis determined two factors (factor 1: physical activity/exercise, fruit and vegetable consumption, and factor 2: alcohol abuse tobacco use and drug abuse), explaining 67.78% of variance by the items and six interactions χ2/gL=11649.833; p&lt;0.001. Conclusion Behavioural Lifestyle Changes Questionnaire was seen to have suitable internal consistency and validity. This instrument can be recommended, mainly within the context of primary attention for studying the stages involved in the lifestyle behavioural changes model on a school-based population.

title: Associations between taste sensitivity, preference for sweet and salty flavours, and nutritional status of adolescents from public schools

description: ABSTRACT Objective This study aimed to investigate the associations between taste sensitivity, preference for sweet and salty flavours, and nutritional status of adolescents in public schools. Methods We used a cross-sectional study involving 1,036 adolescents of both sexes, aged 10-19 years. Preference for sweet or salty flavours and preference for foods high in sugar or sodium were evaluated. Measurements of body mass index and taste flavour intensity recognition were conducted. Results Most participants were unable to identify the flavours and/or intensities, and only 18.0% of participants were able to correctly identify both the flavour and intensity of the samples. Most participants (82.1%) preferring sweet foods had low sensitivity to this taste, just as a large proportion of individuals preferring saltiness (82.3%) were less sensitive to salt (p&lt;0.001). Preference for saltiness was associated with pre-obesity. Conclusion We found an association between a preference for sweet or salty flavours and nutritional status, highlighting the importance of poor food choices in the development of obesity and other chronic diseases.

title: Association between screen time and dietary patterns and overweight/obesity among adolescents

description: ABSTRACT Objective The association between screen time and dietary patterns and overweight/obesity among adolescents was analysed in this study. Methods In this cross-sectional study, 963 Brazilian adolescents, aged between 11 and 14 years were evaluated. Body mass index was used to assess overweight/obesity. Dietary patterns and screen time were assessed using qualitative questionnaires. Principal component analysis was used to obtain dietary patterns. Confounder variables were: type of school (public or private), sexual maturation, mother’s weight and mother’s education. The Chi-square test was used for the crude analysis; for the adjusted analysis was used Poisson regression with sample weighting. Results Overweight/obesity prevalence was 29.8% and statistically higher among boys (34.7%). Higher screen time prevalence was 39.1%. The dietary patterns obtained were: obesogenic; coffee and dairy products; traditional Brazilian meal; fruit and vegetables; bread and chocolate milk. The dietary pattern that more closely represented student food consumption was the obesogenic pattern. Screen time was not significantly associated with overweight/obesity. The obesogenic pattern (in both sexes), the coffee and dairy products pattern, and the bread and chocolate milk pattern (only in girls), were inversely associated with overweight/obesity. In this study, dietary patterns influenced overweight/obesity, although in some cases, in an inverse way from what expected. Conclusion A high prevalence of overweight/obesity and a high proportion of screen time activities among the adolescents were observed. Our results indicate a high consumption of unhealthy dietary pattern among adolescents.

title: Evaluation practices in the field of Food and Nutrition

description: ABSTRACT The objective of this study was to characterize and analyze the different existing methods for the evaluation of food and nutrition programs and services in Brazil, through a systematic review of the literature focused on complete articles published in national indexed journals. We searched the PubMed, MedLine and LILACS databases using the following search terms and Boolean operators: “evaluation and program”; “project”; “intervention”; “servisse”; “actions and nutrition”; “nutritional”. The research was restricted to articles written in Portuguese, English and Spanish and published between 2001 and 2015. Twenty-two studies were selected and the analysis indicates; most were carried out through quantitative approaches and external evaluations based on epidemiological theory; participatory evaluation strategies are still uncommon; Impact assessments and implementation were predominant; there is little diversity in terms of references to the theoretical framework in the field of evaluation of health care programs in the planning and execution of the evaluation processes analyzed. The results of this study indicate the need for a more comprehensive evaluation considering the complexity of the interventions evaluated using the theoretical-methodological apparatus available in the literature to understand the importance of the different perspectives of the agents involved in the evaluation processes.

title: Comparison of the effects of continuous versus intermittent enteral feeding on plasma leptin and ghrelin levels in Intensive Care Units

description: ABSTRACT Objective: The aim of this prospective randomized trial is to verify whether there is an association between the methods of administration of enteral nutrition and the leptin and ghrelin hormones, which have a major role in the regulation of energy metabolism. Methods: This study enrolled 38 enteral-fed patients aged 18 to 85 in the Intensive Care Unit. The patients were prospectively randomized to receive either continuous infusion (n=19) or intermittent feeding (n=18) of enteral nutrition. In addition to routine biochemical assays, blood samples were taken from the patients for leptin and ghrelin analyses on the 1th, 7th, and 14th days of enteral nutrition. Results: There was no statistically significant difference between the groups regarding descriptive statistics and categorical variables such as underlying diseases, complications, steroid use and others (p&gt;0.05). The decrease in the number of white blood cells and in creatinine and C-reactive protein levels over time were statistically significant (p=0.010, p=0.026, p&lt;0.001 respectively). There was no statistically significant difference between the groups with respect to leptin and ghrelin levels (p=0.982 and p=0.054). Leptin levels did not change over time; however, the ghrelin levels of both groups were significantly higher on the 7th and 14th days than on the first day of analysis (p=0.003). Conclusion: This study revealed that both continuous and intermittent enteral nutrition feeding regimens were well tolerated in Intensive Care Unit patients showing minor complications. The method of administration of enteral nutrition alone did not affect the leptin and ghrelin levels. Randomized controlled large cohort trials are needed to to compare intermittent and continuous enteral nutrition to determine which one is more adaptable to diurnal patterns of secretion metabolic hormones.

title: Body composition and metabolic profile in adults with vitamin D deficiency

description: ABSTRACT Objective: To investigate the body composition and metabolic profile in individuals in terms of different concentrations of serum vitamin D, ranging from deficiency to sufficiency. Methods: A cross-sectional study of 106 adults of both genders, who were divided into three groups according to vitamin D levels: deficiency: &lt;20ng/mL; insufficiency: 20-29.9ng/mL; and sufficiency: 30-100ng/mL. Anthropometric evaluation included weight, height, and body circumferences. Fat mass and lean mass were assessed using the Tetrapolar bioelectrical impedance method. Clinical and biochemical evaluations were also carried out. Insulin resistance was estimated using the Homeostasis Model Assessment Insulin index. Results: The analysis showed that the main alterations in individuals in the vitamin D deficiency group were higher triglycerides, very low density lipoprotein - cholesterol, fasting blood glucose, insulin, glycated hemoglobin, body mass index, body fat percentage, lean mass percentage, waist circumference, and Homeostasis Model Assessment Insulin than those of the vitamin D sufficient group (p&lt;0.05). Conclusion: It was found that vitamin D deficiency causes important body composition and metabolic changes, which may lead to diseases such as diabetes Mellitus and metabolic syndrome.
