title: Hemoglobin concentrations and associated factors in adolescentes from Recife, Brazil

description: OBJECTIVE: To estimate the prevalence of anemia and associated factors in adolescents from the city of Recife in Pernambuco state. METHODS: This is a cross-sectional study, involving a random sample of 256 adolescents of both genders, aged 13 to 18, whose hemoglobin concentrations were evaluated, along with their nutritional status and socioeconomic and demographic characteristics. RESULTS: The prevalence of inadequate hemoglobin concentrations was 10.2% [CI95%=6.7-14.5], reaching levels considered as mild anemia (9 g/dL 0.05), nor with socioeconomic or demographic characteristics (p&gt;0.05). CONCLUSION: Although the prevalence of anemia was low and classified as a mild health problem, preventive nutrition education involving the dissemination of healthy eating habits in schools and encouraging the consumption of iron-rich foods are strongly recommended.

title: Long-term effects of neonatal malnutrition on microbicide response, production of cytokines, and survival of macrophages infected by Staphylococcus aureus sensitive/resistant to methicillin

description: OBJECTIVE: To assess microbicide function and macrophage viability after in vitro cellular infection by methicillin-sensitive/resistant Staphylococcus aureus in nourished rats and rats subjected to neonatal malnutrition. METHODS: Male Wistar rats (n=40) were divided in two groups: Nourished (rats suckled by dams consuming a 17% casein diet) and Malnourished (rats suckled by dams consuming an 8% casein diet). Macrophages were recovered after tracheotomy, by bronchoalveolar lavage. After mononuclear cell isolation, four systems were established: negative control composed exclusively of phagocytes; positive control composed of macrophages plus lipopolysaccharide; and two testing systems, macrophages plus methicillin-sensitive Staphylococcus aureus and macrophages plus methicillin-resistant Staphylococcus aureus. The plates were incubated in a humid atmosphere at 37 degrees Celsius containing 5% CO2 for 24 hours. After this period tests the microbicidal response, cytokine production, and cell viability were analyzed. The statistical analysis consisted of analysis of variance (p&lt;0.05). RESULTS: Malnutrition reduced weight gain, rate of phagocytosis, production of superoxide anion and nitric oxide, and macrophage viability. Production of nitrite and interleukin 18, and viability of macrophages infected with methicillin-resistant Staphylococcus aureus were lower. CONCLUSION: The neonatal malnutrition model compromised phagocyte function and reduced microbicidal response and cell viability. Interaction between malnutrition and the methicillin-resistant strain decreased the production of inflammatory mediators by effector cells of the immune response, which may compromise the immune system's defense ability.

title: Association of socioeconomic, labor and health variables related to Food Insecurity in workers of the Popular Restaurants in the city of Rio de Janeiro

description: Objective: This study aimed to analyze the prevalence of perceived food insecurity in households of employees of Popular Restaurants, as well as associate this perception with socioeconomic, labor and health variables. Methods: This is a cross-sectional study of 273 workers from seven restaurants located in the city of Rio de Janeiro, Brazil. We applied a questionnaire with different scales and anthropometric measurements were taken. Assessment of food insecurity was performed using the Brazilian Food Insecurity Scale, classifying individuals in food security and food insecurity. The analyses were performed by calculating the gross and adjusted odds ratio. The logistic regression was performed considering three groups of variables: socio-economic, employment and health. Results: The estimated prevalence of food insecurity was 53.7%. The variables: education (OR=2.39; 95%CI=1.38-4.16), time working in kitchens &lt;29 months (OR=2.72; 95%CI=1.44-5.16) and opinion on the satisfaction with food composition and regularity (OR=2.01; 95%CI=1.12-3.57) were significantly associated with food insecurity. Conclusion: Although the study population find themselves inserted into a social facility to promote food security, food insecurity results are worrying. Additionally, factors like lower education and less time working in restaurants increased the chance to realize their households in food insecurity.

title: School canteens in the Federal District, Brazil and the promotion of healthy eating

description: Objective: To characterize the school cafeterias in the Federal District of Brazil with respect to the promotion of healthy eating in schools. Methods: This is a descriptive, analytical, cross-sectional study, with a representative sample of schools with cafeterias in the Federal District, Brazil (n=202). The data were collected from April to November 2010 by means of on-site interviews and a structured questionnaire. The Pearson's chi-squared and Student's t tests were used. Results: A higher prevalence of outsourcing, and few employees and dieticians were observed. The prevailing foods were baked sausage, cheese, or chicken rolls or pastries. It was also found that 42.2% of the schools influence the menu of the cafeterias, and 58.6% of the representatives believe in the possibility of influencing the students' eating habits. However, 68.0% of the respondents do not believe in the economic feasibility of completely healthful school cafeterias. Approximately 30.0% of the respondents carry out activities to promote healthy eating. Conclusion: Most of the school cafeterias in the Federal District do not encourage healthful eating. The high prevalence of outsourced services with little interference from the school community gives high autonomy to the cafeteria's owner, whose priority is the pursuit of profit at the expense of the students' nutritional education. Improving the nutritional quality of school foods should be a continuous interactive effort of the food suppliers, principals, students, parents, and government authorities.

title: Food habits and risk of cardiovascular disease in schoolchildren from Ouro Preto, Minas Gerais

description: OBJECTIVE: To investigate the relationship between food habits and risk factors for cardiovascular disease in schoolchildren of the city Ouro Preto, Minas Gerais. METHODS: A cross-sectional study was conducted in a population-based sample of 738 schoolchildren aged 6-14 years. A semi-structured questionnaire was used for collecting demographic, socioeconomic, biochemical, clinical, and anthropometric data. Food intake was determined by a food-frequency questionnaire. Food habits were evaluated according to the adapted Recommended Food Score. Multiple linear regression models were constructed to assess how food consumption was associated with cardiovascular risk factors. RESULTS: The schoolchildren presented a dietary pattern characterized by low consumption of healthy foods. Association of cardiovascular risk factors showed that the consumption of foods according to the adapted Recommended Food Score was negatively and significantly associated with tetrapolar percentage of body fat (p=0.030) and systolic blood pressure (p=0.049) in children aged 6-9 years. CONCLUSION: Children's dietary patterns proved to be an important determinant of some of the cardiovascular risk factors studied. Thus, food intake assessment is a primary tool for the prevention and early intervention on cardiovascular risk factors during childhood.

title: Estimate of consumption of phenolic compounds by Brazilian population

description: OBJECTIVE: Estimate the intake of phenolic compounds by the Brazilian population. METHODS: To estimate the average per capita food consumption, micro data from the National Dietary Survey and from the Household Budget Survey from 2008 to 2009 was analyzed. The phenolic content in food was estimated from the base of Phenol-Explorer. It was chosen according to compatibility and variety of food items and usual method of preparation. RESULTS: The Brazilian population consumed, on average, 460.15 mg/day of total phenolic compounds, derived mainly from beverages (48.9%), especially coffee and legumes (19.5%). Since this analysis of classes of phenolics it was possible to observe an intake of 314 mg/day of phenolic acids, 138.92 mg/day of flavonoids and 7.16 mg/ day of other kinds of phenolics. Regarding the variables studied this present study shows that those men who live in the countryside and in the northeastern region of the country had a higher consumption of phenolic compounds. Besides, consumption was higher by adults and the elderly, the medium income classes, the population with incomplete and complete primary education and those with adequate nutrition and also overweight status. CONCLUSION: The intake of phenolic compounds can be considered low, especially where consumption of fruit and vegetables is insufficient. We can conclude that coffee and black beans were the best contributors to phenolic intake.

title: Education and work of dieticians from Family Health Support Centers

description: OBJECTIVE: The aim of this study was to analyze the education and work of dieticians from the Family Health Support Centers in the state of Goiás. METHOD: This is a descriptive, exploratory, cross-sectional study with dieticians from these centers. The dieticians answered a self-administered questionnaire with open and closed questions that characterized them, their education, and their work. RESEARCH: Twenty-two female dieticians from Family Health Support Centers participated in the study, representing 88.0% of the total. Of these, 59.1% had graduated less than three years ago; 13.6% specialized in family health; and only 27.3% felt capable of performing their job based on a reflection about the socioeconomic, political, and cultural reality of the territory. Regarding work, 80% had temporary job contracts, which can compromise the bond between the professionals and the population; 36.4% had been working for less than one year; 18.2% received training before they started working; and 59.1% did not feel sufficiently trained to work in the centers. Only 9.1% of the participants discussed matriciamento (support given by a multidisciplinary team to another multidisciplinary team) in the meetings and used tool-related references. Team work was considered a facilitator of their actions, and not knowing the role of Family Health Support Centers was considered a hindrance. CONCLUSION: Dieticians from the Family Health Support Centers in the state of Goiás have little professional experience, do not feel sufficiently trained to work in family health, and have difficulties understanding the local reality, as education did not give them confidence to work in the area and they have little knowledge about the centers.

title: Waist circumference percentiles in adolescents in the city of Rio de Janeiro, Brazil

description: OBJECTIVE: To determine waist circumference and present waist circumference critical values to classify the risk and high risk posed by excessive abdominal fat according to age and gender. METHODS: A probabilistic sample of adolescent students (n=3,175) from public schools in Rio de Janeiro was analyzed. Waist circumference measurements were performed at midpoint between the last rib and the top of the iliac crest. Waist circumference percentiles were estimated using the LMS (Lambda, Mu, Sigma) method proposed by Cole (1990). The cut-points used to determine the risk and high-risk posed by excessive abdominal fat were proposed by Jolliffe & Janssen (2007). RESULTS: Comparing the values estimated, it was observed that the girls had higher waist circumference than the boys at all percentiles (except for P90) and ages. The estimated percentiles were lower in girls and increased with age in both sexes. At all ages, (except for 17 year old boys) and both genders, the estimated values were lower than the reference values used. CONCLUSION: The results obtained confirm the importance of measuring waist circumference in adolescents. This study presents waist circumference critical values for the anthropometric classification of the group studied, which has not yet been reported in the literature with data of Brazilian adolescents.
