title: Vitamin A deficiency and factors associated with retinol levels in public school students

description: ABSTRACT Objective To estimate the prevalence of vitamin A deficiency and determine the socioeconomic and demographic factors associated with serum retinol levels in public school students. Methods This cross-sectional study included 245 students from the urban and rural areas of the city of Teresina, Piauí, Brazil. Socioeconomic data were collected using a form. Serum retinol level was determined by high-performance liquid chromatography and classified according to the cut-off points provided by the World Health Organization. All statistical tests had a significance level of 5%. Results The prevalence of vitamin A deficiency (retinol level &lt;0.70µmol/L) was 9.8% (95%CI=7.9-10.0). The prevalences of low and acceptable retinol levels (&lt;1.05mol/L) were higher in students aged 12-14 years living in households without piped water supply (p&gt;0.05). Water well or other untreated water sources were the factors most strongly associated with low retinol levels (OR=3.28; 95%CI=1.48-7.28; p=0.003). Conclusion Vitamin A deficiency was characterized as a mild public health problem in the students, indicating the need of actions that address this issue in schools and of studies with larger samples to investigate the problem at the municipal and state levels. Untreated water intake, a possible source of waterborne illnesses, contributed to lower retinol levels.

title: Skipping breakfast and associated factors among Brazilian adolescents

description: ABSTRACT Objective To analyze the prevalence and factors associated with breakfast skipping among adolescents. Methods Cross-sectional study, with adolescents aged 10-17 years, evaluated between 2009 and 2011, belonging to a cohort study in the Central-West region of Brazil. Breakfast skipping was considered as not having breakfast every day. Demographic, socioeconomic, and lifestyle factors were evaluated through a questionnaire. Anthropometric assessment included measurement of weight and height, which were used to classify weight status using body mass index. Poisson regression was used to assess the association of breakfast skipping with demographic and socioeconomic variables, lifestyle factors, and weight status. Results Among 1,716 Brazilian adolescents evaluated, 36.2% reported not consuming breakfast every day, with the highest prevalence among girls (p=0.03). After adjusting for age and economic class, breakfast skipping was associated with not consuming breakfast with parents and morning shift at school, in both genders, and with obesity only in boys. Lifestyle factors such as alcohol consumption, physical activity, diet quality, and smoking were not associated with skipping breakfast. Conclusion The omission of breakfast was observed in more than a third of adolescents, being associated with demographic and lifestyle factors. In the public health perspective, the importance of encouraging the consumption of this meal is highlighted, with actions involving the school environment and the family.

title: Validation of the Online version of the Previous Day Food Questionnaire for schoolchildren

description: ABSTRACT Objective To evaluate the validity of the web-based version of the Previous Day Food Questionnaire Online for schoolchildren from the 2nd to 5th grades of elementary school. Methods Participants were 312 schoolchildren aged 7 to 12 years of a public school from the city of Florianópolis, Santa Catarina, Brazil. Validity was assessed by sensitivity, specificity, as well as by agreement rates (match, omission, and intrusion rates) of food items reported by children on the Previous Day Food Questionnaire Online, using direct observation of foods/beverages eaten during school meals (mid-morning snack or afternoon snack) on the previous day as the reference. Multivariate multinomial logistic regression analysis was used to evaluate the influence of participants’ characteristics on omission and intrusion rates. Results The results showed adequate sensitivity (67.7%) and specificity (95.2%). There were low omission and intrusion rates of 22.8% and 29.5%, respectively when all food items were analyzed. Pizza/hamburger showed the highest omission rate, whereas milk and milk products showed the highest intrusion rate. The participants who attended school in the afternoon shift presented a higher probability of intrusion compared to their peers who attended school in the morning. Conclusion The Previous Day Food Questionnaire Online possessed satisfactory validity for the assessment of food intake at the group level in schoolchildren from the 2nd to 5th grades of public school.

title: Food consumption pattern and obesity in preschool children in Feira de Santana, Bahia, Brazil

description: ABSTRACT Objective To evaluate the association between food consumption patterns and obesity in preschool children in Feira de Santana, Bahia, Brazil. Methods Cross-sectional, population-based nested within a live-birth cohort study of 813 children, which has started in 2004 in Feira de Santana, Bahia. The anthropometric status among children under four years of age was evaluated based on their body mass index; obesity/severe obesity was defined as a Z-score &gt;+2. The Food Frequency Questionnaire was used to identify dietary patterns using principal components analysis. The association between obesity and food consumption patterns was assessed using Pearson’s Chi-squared test and logistic regression, adopting p&lt;0.05 to denote statistical significance. Results Obesity was detected in 12.7% of the children investigated. Four food consumption patterns were identified: dietary pattern 1 (milk and other dairy products, vegetables and tubers, cereals, legumes, fruits, and fish); dietary pattern 2 (deep-fried or baked snacks, soft drinks/artificial fruit juices, oils and fats, sweets, and coffee/tea); dietary pattern 3 (encased meats, fast food, ketchup/mayonnaise, and eggs); and, dietary pattern 4 (chicken and red meats). Obesity was statistically associated with high adherence to the dietary pattern 3 (OR=1.92; 95%CI=1.01-3.66). Conclusion The results obtained showed that the high intake of energy-dense foods (dietary pattern 3) was a contributing factor to childhood obesity. These data reinforce the need for public policies and food education programs in health units and schools, aiming to change children’s eating habits, significant predictors of nutritional problems.

title: Purchase of family farm and organic foods by the Brazilian School Food Program in Santa Catarina state, Brazil

description: ABSTRACT Objective To describe the purchase of family farm and organic foods by the Brazilian School Food Program in the municipalities of the state of Santa Catarina, Brazil. Methods This is an analytic and descriptive study conducted from 2010 to 2011. An electronic survey was sent to all 293 Santa Catarina municipalities. The Chi-square test investigated the association between the study variables. Results Between 2010 and 2011, the number of municipalities that purchased family farm foods increased by 36%, with a total of 96% of Santa Catarina municipalities buying family farming foods in 2011. Of the 96%, 70% complied with Article 14 of Law nº 11,947/2009, which determines that at least 30% of the funds provided by the National Fund for the Development of Education should be spent on family farm products, and 48% purchased organic foods. The South was the state region that most complied with Article 14 (85%; p=0.02). However, as municipality size increased, compliance with Article 14 decreased (p=0.04). The municipalities that had the most difficulties buying family farm and organic foods were those with the lowest Municipal Human Development Index and number of students. Conclusion Most Santa Catarina municipalities purchased family farm foods in 2011, and most municipalities that complied with Article 14 of Law nº 11,947/2009 were in the South state region. Finally, municipalities with low Municipal Human Development Index and number of students had the most difficulties buying family farm foods.

title: Added sugars: Definitions, classifications, metabolism and health implications

description: ABSTRACT The sugars added to foods have been featured in recent scientific research, including the publication of the World Health Organization recommendation to limit consumption of added sugars, based on studies on weight gain and dental caries. However, it is possible that there is evidence of an association between excessive consumption and other pathologies, but scientific studies have yet to investigate these associations. Moreover, there is no consensus on the descriptions and definitions of these sugars, with several terms and components used to designate them. In Brazil, there are few studies investigating added sugars, identifying a lack of discussion on this subject. This paper presents a literature review of sugars added to foods, from their definitions and classifications to the metabolism and health effects. The search was performed without limiting dates in the following databases: Web of Science, Scopus, PubMed and SciELO, as well as in national and international official sites. Keywords in Portuguese and English related to sugars added to foods were used, in combination with terms related to systematic review and meta-analysis studies, in order to find research linking added sugars consumption with health damage. The literature indicates that there is a relationship between excessive consumption of added sugars and various health outcomes, including weight gain, type 2 diabetes Mellitus, cancer, and cardiovascular diseases. The different descriptions of sugars in foods may confuse both food consumers and researchers, since each term includes different components. Thus, it is suggested to use the standardized term “added sugar” as the most suitable term for the broader population to understand, because it indicates that those sugars are not natural food components.

title: Perception versus intake of fruit and vegetables

description: ABSTRACT Objective To compare perception and intake of fruit and vegetables, and to identify the factors associated with misperception of intake. Methods Cross-sectional study with 3,414 participants of the Health Academy Program from Belo Horizonte (MG), Brazil. Stages of change from Transtheoretical Model were used to evaluate perception of intake, and questions adapted from national surveys were used to assess intake of fruit and vegetables as separate groups. Individuals whose intake and perception were discordant were reclassified in pseudo-maintenance (wrongly believe their intake is adequate) or non-reflective action (wrongly believe their intake is inadequate). Results Insufficient intake of fruit and vegetables and misperception of intake were observed. Pseudo-maintenance was more prevalent, given that 45.1% of individuals were reclassified in this stage regarding their vegetable intake and 22.9% regarding fruit. According to multinomial logistic regression, pseudo-maintenance of fruit intake was associated with sex, schooling, food and nutrition security, weight satisfaction, and participation in nutrition interventions; pseudo-maintenance of vegetable intake was associated with schooling and weight satisfaction. Non-reflective action was associated with age. Conclusion An important discordance between perception and intake was found, with emphasis on pseudo-maintenance of vegetable intake. Misperception was associated with different factors regarding fruit and vegetables, including sociodemographic variables, participation in nutrition interventions, and weight satisfaction. These results can contribute to the design of interventions aligned with eating behavior, aimed to empower individuals for their food choices.
