Self-reported type 2 diabetes Mellitus is associated with abdominal obesity and poor perception of health in shift workers
ABSTRACT Objective: To investigate factors that are associated with type 2 diabetes Mellitus in shift workers of a slaughterhouse in Southern Brazil. Methods: This cross-sectional study included 1,194 18- to 50-year-old workers of both sexes. The presence of type 2 diabetes Mellitus was self-reported and confirmed by the use of hypoglycemic drugs or insulin. The independent variables were sex, age, skin color, marital status, education level, family income, leisure time physical activity, smoking, and self-reported health and nutritional status (body mass index and waist circumference). Multivariate analysis was performed from an a priori conceptual model. Results: The prevalence of diabetes was 1.3% (95%CI=0.6-1.9). Type 2 diabetes Mellitus was associated with poor or regular self-reported health (OR)=3.72; 95%CI=1.28-10.78) and level II abdominal obesity ³102 for men and ³88 for women (OR=5.76; 95%CI=1.07-29.10). Conclusion: The prevalence of type 2 diabetes Mellitus was low. Moreover, the study evidenced the importance of using waist circumference to surveil and screen for metabolic diseases, such as type 2 diabetes Mellitus, and to monitor the low quality of life in the study individuals given the poor self-perceived health of workers with the said disease.

Conjugated linoleic acid supplementation does not maximize motor performance and abdominal and trunk fat loss induced by aerobic training in overweight women
ABSTRACT Objective: To analyze the effect of eight weeks of conjugated linoleic acid supplementation on physical performance, and trunk and abdominal fat in overweight women submitted to an aerobic training program. Methods: Twenty-eight overweight women (body mass index ³25 kg/m2) were divided randomly and double-blindly to receive conjugated linoleic acid or placebo, both associated with an aerobic exercise program (frequency = three times a week, duration=30 min/session, intensity=80% of maximum heart rate). Conjugated linoleic acid (3.2 g) and placebo (4.0 g) supplements were consumed daily (four capsules) for eight weeks. Maximum speed and time to exhaustion were determined in incremental treadmill test. Trunk fat was estimated by dual-energy X-Ray absorptiometry. Waist circumference was used as indicator of abdominal fat. Results: Main effect of time (p<0.05) showed increased maximum speed (conjugated linoleic acid=+6.3% vs. placebo=+7.5%) and time to exhaustion (conjugated linoleic acid=+7.1% vs. placebo=+8.6%) in the incremental treadmill test, with no differences between the groups (p>0.05). Similarly, significant reductions (p<0.05) in trunk fat (conjugated linoleic acid=-1.7% vs. placebo=-1.5%) and abdominal fat (conjugated linoleic acid=-4.7% vs. placebo=-4.0%) were found after eight weeks of intervention, with no differences between the groups (p>0.05). Conclusion: The results of this study suggest that conjugated linoleic acid supplementation does not maximize motor performance, and loss of body and abdominal fat induced by aerobic training in overweight women.

Cross-cultural equivalence and psychometric proprieties of the social support scale for healthy eating habits
ABSTRACT Objective: To assess the cross-cultural equivalence and psychometric proprieties of the Brazilian version of the Eating Habits Social Support Scale. Methods: The scale was administered to 381 subjects aged 24 to 86 years from Recife and Belo Horizonte, Brazil. Cross-cultural equivalence was evaluated by expert agreement. The psychometric proprieties were assessed by factor validity (factor analysis), internal consistency (Cronbach's alpha), and reproducibility (intraclass correlation coefficient), using a test-retest with an interval of seven days. Results: Factor analysis identified two factors for each social support group (friends and family). The questions were clustered by type of social support (positive or negative comments). The eigenvalues for family social support were 3.22 and 3.00, corresponding to 62.2% of the total variance. For friend social support, the eigenvalues were 3.02 and 2.95, explaining 59.7% of the total variance. In the internal consistency analysis, the alpha values ranged from 0.83 to 0.75. The reproducibility intraclass correlation coefficient ranged from 0.676 to 0.873. All these values were acceptable, indicating the validity and reliability of the scale. Conclusion: The Brazilian version of the Eating Habits Social Support Scale presented cross-cultural equivalence and psychometric characteristics that were appropriate for Brazilian adults and older adults. This scale is easy to use and obtained high scores for question clarity and answer options.

Healthy eating at school: consensus among experts
ABSTRACT Objective: To identify attributes that promote healthy eating in order to support a study for the Quality Index for School Meal Menus content validity. Methods: This study used the Delphi technique to consult school nutrition experts in Brazil. These experts were selected among the authors of articles published between 2010 and 2015 that were identified by searching the Web of Science database, using the keywords 'school feeding', 'school nutrition program', and 'school food program', as well as the authors of official documents on this topic. The Likert method was used to record respondent perceptions in two analytical dimensions: foods that are part of a healthy menu for school feeding, and composition of an indicator of nutritional quality for school feeding menus. Results: Most respondents (n=27) were affiliated with public institutions (92.59%) and had over six years of experience in the area (70.36%). Assertions resulted in consensus according to the analysis criteria. A consensus was established for fresh food, fruits and vegetables, dairy products, beans, meat and eggs, and a schedule compatible with the meal as promoters of healthy eating, and processed foods, sweets, and fat excess as risk attributes. Conclusion: Since a consensus was not reached in the first round, there is a need to broaden the debate on issues related to foods rich in sugar, replacement of meals by sweets, and foods rich in fat.

Analysis of the presence of nutrient claims on labels of ultra-processed foods directed at children and of the perception of kids on such claims
ABSTRACT Objective: To characterize the presence of nutrient claims on the front-of-pack labels of ultra-processed foods directed at children and gain insight on children' views about the presence of marketing strategies and nutrient claims on labels of ultra-processed foods. Methods: Analysis of images (front panel, nutrition facts table, and ingredients list) of labels from 535 packaged foods with marketing strategies directed at children obtained in an audit-type survey conducted at a Brazilian large supermarket store. Food products with ultra-processed characteristics were identified, and the nutrient claims were quantified and described. Focus groups were conducted with children aged 8-10 years. Results: A total of 472 (88.0%) of the 535 packaged foods directed at children were classified as ultra-processed. Of these, 220 (46.6%) had one or more nutrient claims on their front-of-pack label (n=321), most (n=236, 73.5%) claiming the presence/increased quantities of vitamins and minerals. The most common 'free/reduced' content claim regarded trans fat content (n=48). The focus groups allowed the identification of a noticeable influence of nutrition claims on children, who considered the emphasis important but were confused by the meaning and focus of such claims. Conclusion: Highlighted nutrient claims on the packages of ultra-processed foods were common and seemed to influence the children's perception of the products' quality as a whole. The results indicate the need of thoroughly reviewing the legislation on nutrient claims on the packages of ultra-processed foods.

Impact of the Bolsa Família Program on energy, macronutrient, and micronutrient intakes: Study of the Northeast and Southeast
ABSTRACT Objective: To assess the impact of the Bolsa Família Program on the energy and nutrient intakes of beneficiaries from the Brazilian Northeast and Southeast regions. Methods: The study used data from the 2008-2009 Pesquisa de Orçamento Famíliar, which assessed individual food intake on two nonconsecutive days of individuals aged more than 10 years. Based the personal information booklet, food intake values were transformed into nutritional values (energy and nutrients). Analysis of the impact measure was preceded by propensity score matching, a technique that matches some socioeconomic characteristics of beneficiaries and nonbeneficiaries. Once the score was calculated, the impact of the Bolsa Família Program was estimated by nearest neighbor matching. Results: The program increased energy and macronutrient intakes and decreased calcium and vitamin A, D, E, and C intakes of adolescent beneficiaries in both regions. Adult beneficiaries from the Southeast region increased their fiber, iron, and selenium intakes, and those from the Northeast region decreased their energy, lipid, added sugar, sodium, zinc, vitamin E, and pyridoxine intakes. Conclusion: The results show a positive impact of the program on the energy and macronutrient intakes, and a negative impact on the intakes of most study micronutrients, especially in adolescents, which reinforce the importance of implementing intersectoral actions to improve the nutritional quality of the Bolsa Família Program beneficiaries' diet.

Demographic and socioeconomic conditions associated with food insecurity in households in Campinas, SP, Brazil
ABSTRACT Objective: To evaluate the association of food insecurity with demographic and socioeconomic conditions in households in Campinas, São Paulo state, Brazil. Methods: This is a cross-sectional study conducted on a representative sample of the urban population of the Southern, Southwestern, and Northwestern Health Districts of Campinas, between 2011-2012. Characteristics of the head of household, family history and household patterns were investigated. The dependent variable was food security condition, categorized as food security, mild food insecurity, and moderate/severe food insecurity. All independent variables with p-value <0.20 in the bivariate multinomial logistic regression were included in the final model of multiple multinomial logistic regression, adjusted to household head age; the remaining variables had p-value <0.05. Results: In the 691 households analyzed, there was 65% of food security, 27.9% of mild food insecurity, and 7.1% of moderate/severe food insecurity. The conditions associated with mild food insecurity were monthly per capita income less than the minimum wage, household head unemployed for more than six months between 2004-2010, living in properties given to the family/occupied/other, and density higher than two people per bedroon. The moderate/severe food insecurity was associated with informal employment condition of the household head and the presence of a beneficiary of the Bolsa Família (Family Allowance Program), a cash transfer-type program, in the household. The higher the score of the consumer goods, the lower the probability of mild food insecurity or moderate/severe food insecurity. There was a higher probability of mild food insecurity and moderate/severe food insecurity in unfinished masonry-built houses/other. Conclusion: More than one third of the households investigated experienced some form of food insecurity. Mild food insecurity was associated with demographic conditions, while moderate/severe food insecurity was associated with socioeconomic conditions, especially those related to the household head.

Oilseeds native to the Cerrado have fatty acid profile beneficial for cardiovascular health
ABSTRACT Objective: To assess and compare the fatty acid composition of edible seeds and a nut native to the Cerrado (Brazilian savannah) to that of traditional oilseeds. Methods: Baru almonds, Cerrado cashew nuts, and pequi almonds were extracted from the fruits using appropriate equipment. All edible seeds and nuts were roasted, except for the Brazil nut. The sample lipids were extracted via cold pressing. The fatty acids were esterified, and the fatty acid esters were analyzed by gas chromatography. Results: The native and traditional edible seeds and nuts contain mostly monounsaturated fatty acids (42.72 g to 63.44 g/100 g), except for the Brazil nut, which showed predominance of polyunsaturated fatty acids (45.48 g/100 g). Pequi almond had the highest saturated fatty acid content (36.14 g/100 g). The fatty acids with the highest concentration were oleic and linoleic acids, and palmitic acid was also found in considerable concentration in the oilseeds studied. The Cerrado cashew nut and the traditional cashew nut have similar fatty acid profiles. As for the ratio of ω-6 to ω-3, the baru almond showed the highest ratio, 9:1, which was the closest to the recommended intake of these fatty acids. Conclusion: The fatty acid profile of the edible seeds and nuts native to the cerrado is similar to those of traditional oilseeds. We suggest the inclusion of native oilseeds in the diet aiming at reducing the risk of cardiovascular disease, especially the baru almond and the cerrado cashew nut, due to the fact they have high ratio of monounsaturated fatty acids to saturated fatty acids.

Multidisciplinary programs for obesity treatment in Brazil: A systematic review
ABSTRACT This study aimed to conduct a systematic review of publications addressing the multidisciplinary treatment of obesity in Brazil and analyze their main results. A search was conducted in the databases SciELO, Lilacs, and Pubmed/Medline using the following search terms: 'obesidade', 'intervenção', 'tratamento', 'Brasil', for the search in Portuguese, and 'obesity', 'intervention', 'treatment', 'Brazil', for the search in English. Based on these terms, the following combination of words was used: 'Intervenção multiprofissional da obesidade', 'tratamento multidisciplinar da obesidade, tratamento multiprofissional da obesidade' and 'multidisciplinary obesity intervention', 'multidisciplinary obesity treatment', 'Multiprofessional obesity treatment'. Inclusion criteria were as follows: original studies carried out in Brazil involving human beings and that reported an intervention including two or more health care professionals. Articles published between January 2005 and July 2015 were analyzed independently by two reviewers. At the end of the analysis, out of 355 articles initially selected, 26 met all inclusion criteria. The following results were found: 23 studies involved children and adolescents and 03 involved adults 20-60 years of age. It was also found that the 26 studies analyzed had an impact on anthropometric parameters, 10 on physical fitness parameters, 16 on biochemical parameters, 10 on the reduction in comorbidities, 6 on nutritional parameters, and 4 on the psychological/social aspects. Based on evidence presented in the studies reviewed, it can be said that the multidisciplinary treatment for obesity greatly contributed to the reduction in the anthropometric indicators, especially BMI and the biochemical, social, and psychological parameters. Thus, these findings demonstrate that there is a need to expand the range of this type of treatment since it has proven to be effective in the fight against obesity and its comorbidities.

Analysis of nutrition (and food) education syllabus of nutrition undergraduate courses
ABSTRACT Objective: To analyze the Nutrition Education discipline syllabus in Nutrition undergraduate courses in Brazil. Methods: This is a qualitative, exploratory, descriptive cross-sectional study, carried out in the form of survey. A letter of invitation was sent to higher education institutions that had at least one class that graduated by the end of the first semester of 2010 and provided the Nutrition education discipline syllabus. The software Analyse Lexicale par Contexte d'un Ensemble de Segments de Texte (Image, Toulouse, França) version 4.7 was used in the textual data analysis of the syllabuses, and the social representation theory was adopted as the theoretical model. Results: Data were obtained from 46 participant higher education institutions (11.7%), of which 18 were public institutions. Lexical analysis revealed the formation of two independent axes, which were composed respectively of words from the reference list of relevant books and articles included in the discipline syllabus and words related to the discipline program, indicating a lack of association between "reference list" and "text". As for the syllabus content, it was observed that the educational process should be composed of analysis, planning, and implementation, but these three steps (defined by classes) do not seem to be related or connected to each other, demonstrating a nutrition (and food) education teaching gap. Conclusion: This analysis revealed the need to restructure the nutrition education syllabuses to promote greater integration between theory and practice. However, in order to ensure higher qualification and competence of future professionals, it is suggested deeper consideration including the political-pedagogical projects of nutrition undergraduate programs and the Diretrizes Curriculares Nacionais (National Curriculum Guidelines).

Binge eating under a complex reading: Subsidies for the praxis of food and nutrition education
ABSTRACT Binge eating disorder is characterized by the consumption of large amounts of food in a short time, accompanied by the feeling of lack of control, remorse and guilt. binge eating disorder has a close interface with the obesity problem, a matter of great dimensions for health services, especially for the high comorbidity. Although this disorder is closely linked to obesity, a matter of great dimensions for healthcare, especially due to it high comorbidity, this disorder is still poorly known in its symbolic dimension, compromising actions directed to this dimension, among them those included in the scope of food and nutrition education. The purpose of this article is to delimitate the issue of binge eating disorder, under a lens based on complex thinking, in order to discuss and support the scope of the nutritional eating education, illustrating, with life experiences, the multidimensionality inherent to eating disorders. The analysis aims to highlight the challenge of working in educational practices focused on these complex disorders. Therefore, we articulated the theoretical with the empirical levels, revisiting, through a reflexive exercise, the discursive material obtained in a broad research carried out by the authors, guided by phenomenological-hermeneutics approach focusing on the understanding of binge eating disorder, with obese women who have also received this diagnosis. The analysis highlights binge eating disorder as an intense experience of suffering, which compromises the ability to innovate and reinvent behavior, in which food operates as an emotional cushion. In this context, healing requires taking an active and engaged place, feeling an active part in the self-transformation process. Thus, food and nutritional education should be conceived in the scope of a comprehensive care, as a fundamental and strategic space due to the specific nature of the practice, in potential terms.

Pictorial instrument of food and nutrition education for promoting healthy eating
ABSTRACT To trace the course of building a pictorial instrument that explores semiotic resources about food and nutrition education. The instrument is directed at the treatment and prevention of obesity, considering the food and nutrition problems of the Brazilian population. The criteria for photo production were: images that could cause visual impact and transmit applied nutrition information, insinuating positive and negative eating practices for promoting healthy eating, and preventing and treating obesity. Themes were created to guide photo production, and preparations, food composition tables, and food labels were used for composing the images. Focus groups were conducted with nonobese and obese women, and dietitians to evaluate image comprehension. The pictorial instrument totaled to 20 photos, with 5 photos in each of the following themes: 'Sweet life, being aware of sugar', about sugar content in sweets and drinks; 'Tasty food with little fat', about fat content in foods; 'Eating well by making the best choices', about food replacements; and 'I take care of myself by eating healthy food, about encouraging fruit and vegetable intakes. The photos contain food, meals, and semiotic resources. The pictorial instrument describes four relevant themes to approach food problems in the Brazilian population. It can easily be used for both preventing and treating obesity, and for promoting healthy eating.

International cooperation for food and nutrition security: Systematization of the participatory, contextualized, and intersectoral educational practices
ABSTRACT The present study systematized the experience gained with the project Construindo capacidades em segurança alimentar e nutricional no Brasil, Canadá e Angola (2004-2010, Building food and nutrition security skills in Brazil, Canada, and Angola), whose objective was to qualify actions that promote food and nutrition security in the three countries using different educational practices. The activities were organized in the following subprojects: (a) online distance learning courses; (b) workshops to train managers, government technicians, representatives of civil society organizations, and social subjects who offered to act as a link between communities; and (c) local pilot projects. The present study reports this experience. The educational practices implemented in the municipalities of Araçuaí (MG), Juazeiro (BA), and Fortaleza (CE) were analyzed based on systematized information in the project reports and activity records (texts and photographs). The analytical reference was based on the concept of food and nutrition education, guided by the fundamentals of Popular Education and Paulo Freire; on the concept of food and nutrition security; and on the following analytical dimensions: participation, contextualization of educational practices, and intersectoriality. The results evidenced how educational practices contributed to the construction of shared concepts of food and nutrition security from an intersectoral and participatory perspective that values the peculiarities of diet in different socioeconomic and cultural contexts, and highlights daily situations and local traditions. They also expose the limits and potentialities of an experience of this magnitude, conducted from an interdisciplinarity perspective and using participatory methods.

Nutritional care during prenatal and postpartum periods: A report of experiences in a city on São Paulo's coast
ABSTRACT The purpose of this study is to present a report of the experiences of the adoption of the Approach to Nutritional Care during Prenatal and Postpartum Periods, resulting from a partnership between the university and the municipal primary health care system of Santos, SP, Brazil. This approach was developed through joint work plans based on the need to incorporate nutritional care into the prenatal and postpartum care. All stages of design and implementation and the results of this strategy were documented in a field diary. This approach was adopted in two basic health units between 2010 and 2014. The stages of this process were planned in conjunction with health care teams and consisted of putting together interdisciplinary groups for nutrition education during the prenatal period. Interdisciplinary educational group meetings were held focusing on listening to the needs of pregnant women, the provision of prenatal nutritional care, and on the project to monitor the nutritional status of newborns through home visits up to the 15 days of postpartum. The interdisciplinary activities strengthened the bond between the users and the health care team members, contributing to the provision of effective care and promoting integrality. Home visiting contributed to encourage exclusive breastfeeding.

Scenario of research on Food Service in Brazil
ABSTRACT Objective: The present study aims to investigate the scenario of research on Food Service in Brazil based on the Stricto Sensu Graduate Programs in Nutrition, research groups, and scientific production. Methods: A search of the research lines including studies related to this topic and the researchers engaged in those studies was conducted. The research groups were identified on the Directory of Research Groups in Brazil website and the profile of the scientific production was based on articles included in the Scientific Electronic Library Online database. Articles published in international journals that were related to research lines focused on food production were also searched and analyzed. Results: The search identified only two graduate programs with research lines that describe the food production as the object of study although 13 graduate programs carry out research related to Food Service, especially focused on nutritional and sanitary aspects of food. The same trend was observed in the national articles. The internationalization of these two research line results from the academic publication in 22 different journals over the past 5 years. Thirty five professors were identified and most of them hold a PhD in Food Science and Technology. The number of research groups increased from two in 2000 to twenty nine in 2010. Conclusion: The inclusion of Food Service in graduate programs is still limited. The main trend observed is towards a closer relationship with Food Science and Technology in terms of the lines of research, professional qualification, and published studies.

Intestinal absorption of iron and calcium from soy and cow's milk-based infant formulas in weanling rats pups
ABSTRACT Objective: This study aimed to compare the intestinal absorption of iron and calcium between soy-based and cow's milk-based infant formulas in weanling rats. Methods: Twenty male Wistar rats, twenty-one days old on the first day of weaning, were used in this experiment, divided in two Groups, one Group was fed soy protein-based infant formula the other, cow's milk protein-based infant formula. During the study period (ten consecutive days) the animals received food and water ad libitum. Hematocrit and hemoglobin were evaluated on the first, fifth, and tenth days by the Wintrobe and cyanomethemoglobin methods. Feces and urine were collected, beginning on the fifth day, for three consecutive days. On the tenth day, hepatic iron content was also analyzed. Hepatic iron as well as fecal and urinary iron and calcium analyses were performed using an atomic absorption spectrophotometer. At thirty-one days of age, the animals were anesthetized with ketamine and xylazine and sacrificed by exsanguination via the vena cava. Results: The final concentration of hemoglobin in the group soy-based infant formula and milk-based infant formula were: 10.3±1.3g/dL and 10.9±1.0g/dL (p=0.310). The apparent absorption of iron and calcium, in that order, were: 73.4±10.2% and 70.2±9.5%; 97.2±0.7% and 97.6±1.0% (p=0.501; p=0.290). The apparent calcium retention was: 88.4% ±2.2 and 88.6±2.6% (p=0.848). Hepatic iron content was: 522.0±121.1mg/g and 527.8±80.5mg/g (p=0.907) . Conclusion: Intestinal iron and calcium absorption from soy-based infant formula is similar to that from milk-based infant formula in weanling rats.

Vitamin C decreases the obesogenic and hyperglycemic effect of invert sugar in prediabetic rats
ABSTRACT Objective: To evaluate whether vitamin C can help to prevent obesity and hyperglycemia in Wistar rats treated with excess invert sugar to induce prediabetes. Methods: One hundred-day-old Male Wistar rats with a mean weight of 336.58±23.43g were randomly assigned to the following groups: (1) control, receiving water (C); (2) invert sugar control, receiving a 32% watery solution of invert sugar; (3) vitamin C control, receiving a watery solution of vitamin C (60mg/L), and (4) vitamin C plus invert sugar, receiving a watery solution of vitamin C and invert sugar. All animals had access to chow and water ad libitum and were treated for 17 weeks. Prediabetes was assessed according to two criteria: obesity (based on body mass indexand peritoneal fat content) and impaired glucose tolerance (assessed by the intraperitoneal glucose tolerance test and expressed as area under the curve) . Results: Group invert sugar control gained significantly more weight (p=0.035) and visceral fat (p<0.001) than groups vitamin C control and vitamin C plus invert sugar. Consequently, groups vitamin C control and vitamin C plus invert sugar had gained as little body mass index as group C by the end of the experiment. Vitamin C decreased the fasting glycemia of both groups supplemented with vitamin C and normalized the glucose tolerance of group vitamin C plus invert sugar, whose area under the curve matched that of group C. Conclusion: Vitamin C has anti-obesogenic and glycemia-lowering effects in Wistar rats, which might be promising to prediabetics. Future studies are needed to understand the anti-obesogenic and anti-hyperglycemic mechanisms of vitamin C in prediabetes.

Associated factors of malnutrition among African children under five years old, Bom Jesus, Angola
ABSTRACT Objective: To identify the determinants of wasting and stunting in children under five years old in the commune of Bom Jesus, Angola Methods: A population-based cross-sectional study was conducted with 742 children in 2010, and nutritional deficits were defined by World Health Organization criteria. Prevalence ratios and associated factors of wasting and stunting were estimated using Poisson regression with robust variance, using a conceptual hierarchical model Results: For both deficits, there were significant differences in the prevalence ratios according to the children's neighborhood and age. Boys and those children living in households whose water supply came from the river or lake, as well those with recent expulsion of parasites and infections were more likely to present stunting. Children of fathers with higher number of children or that which the fathers were not living at home and whose mothers were 25-34 years old were less likely to have wasting Conclusion: It was identified independent variables from different levels of determination of malnutrition, standing out the basic sanitation conditions and family structure as important predictors of the nutritional deficits. The knowledge of the associated factors of malnutrition may contribute for subside public policies in planning interventions to improve the childhood nutrition status in Bom Jesus and communes with similar characteristics in Angola.

Excess weight in preschool children: The role of food intake
ABSTRACT Objective: The study aimed to compare the food intake of overweight/obese and normal weight preschoolers and to verify whether excess weight is associated with low birth weight, catch-up growth, early weaning, and physical activity/inactivity Methods: This case-control study was conducted in family healthcare units of the city of Olinda, Pernambuco, from May to August 2014 Results: A total of 253 children were studied, 84 with 'excess weight' and 164 with 'normal weight'. In the 'overweight/obese' and 'normal weight' groups, 77% and 43% of the children, respectively, had high calorie intake. The 'overweight/obese' group had lower fruit intake, higher maternal education level, higher family income, higher maternal excess weight, and presence of catch-up growth and inactivity Conclusion: The results suggest that food intake has an important role, but that other variables contribute to excess weight in children. Recognition of the problem's many causes should guide the public policies directed at this age group to prevent this nutritional disorder.

Nutritional status variation and intestinal and extra intestinal symptomatology in patients with celiac disease and non-celiac gluten sensitivity given specialized dietary advice
ABSTRACT Objective: To investigate the nutritional status variation and symptomatology of patients with celiac disease and non-celiac gluten sensitivity after specialized dietary advice Methods: This prospective study included 80 patients with celiac disease and non-celiac gluten sensitivity. Clinical, metabolic, and nutritional variables were collected from medical records, and the symptomatology was investigated by the Metabolic Screening Questionnaire. The variables were assessed on two occasions (T1 - before dietary advice and T2 - after dietary advice) with an interval of three months between T1 and T2 Results: The median age was 42 years. The prevalences of celiac disease and non-celiac gluten sensitivity were 66.2% and 33.8%, respectively. Normal weight prevailed at T1 (58.8%) and T2 (56.3%), but 30.0% of the patients at T1 and 34.9% of the patients at T2 had excess weight. The two conditions had similar symptomatology. The most frequent signs and symptoms on both occasions involved the gastrointestinal tract, followed by energy/activity and emotions. All symptoms decreased significantly after the introduction of a proper diet Conclusion: The patients were normal weight on both study occasions (T1 and T2), and the symptoms improved after dietary advice. Thus, we reinforce the importance of proper dietary management in both clinical conditions to make dietary adjustments that improve these individuals' symptomatology.
