title: Association between sociodemographics factors and dietary patterns during pregnancy

description: OBJECTIVE:To investigate the association between socio-demographic factors and dietary patterns in pregnancy.METHODS:Cross-sectional study with baseline data from a cohort of 421 postpartum women aged 18 and 45 years resident in Rio de Janeiro,Brazil. Dietary intake was evaluated with a validated food frequency questionnaire at 15 days following delivery, having as time frame the second and third pregnancy trimesters. Dietary patterns were identified using factor analysis for principal components analysis. The association between socio-demographic factors and the identified dietary patterns was assessed with multiple linear regression analysis.RESULTS:Two dietary patterns were identified: i) healthy: fruits; green vegetables; vegetables; fish; roots, corn and potato; milk and dairy and herbal tea mate, and negatively loadings for alcohol and coffee and ii) mixed: rice; bean; flour and pasta; breads; cake and cookies; soda and juice; sugar and sweets; fatty foods; meats; chicken; and eggs. The linear regression showed that the income (β=0.0002; 95%CI: 0.0002-0.0004) and schooling (β=0.0491; 95%CI: 0.0264-0.0718) were positively associated with healthy pattern, and parity (β=-0.1044; 95%CI: -0.1665- -0.0423) and skin color (β=-0.3102; 95%CI: -0.5256- -0.0947) were negatively associated. Skin color (β=0.1647; 95%CI: 0.0378- 0.2916) and marital status (β=0.1065; 95%CI: 0.0062- 0.2067) were positively associated with mixed pattern and income (β=-0.0001; 95%CI:-0.0002- -0.0001) and schooling (β=-0.0281; 95%CI: -0.0417- -0.0146) were negatively associated.CONCLUSION:Socio-demographic factors such as income, schooling, skin color, marital status and parity were associated with dietary patterns in this sample of postpartum women residents in Rio de Janeiro.

title: Resveratrol reduces chronic inflammation and improves insulin action in the myocardium of high-fat diet-induced obeserats

description: OBJECTIVE:To evaluate the effects of resveratrol on insulin signaling and inflammation pathway in the myocardium of high-fat diet-induced obese rats.METHODS:Thirty Wistar rats were divided into a control group (n=10, standard diet), obese group (n=10, high-fat diet), and obese supplemented with resveratrol group (n=10, 20 mg/kg/day) for eight weeks. An insulin tolerance test was performed at the end of the study period "0" (without insulin), 5, 10, 15, 20, 25, and 30 minutes after an intraperitoneal injection of insulin (2 U/kg). Body and epididymal adipose tissue were weighed. Fragments of the myocardium were extracted for Western blot analyses of insulin pathway and proinflammatory molecules.RESULTS:Resveratrol increased the rate of glucose disappearance, phosphorylation of the insulin receptor, insulin receptor substrate 1, and protein kinase B; and reduced expression of tumor necrosis factor alpha and of the molecules involved in proinflammatory signal transduction, namely Ikappa B kinase and nuclear factor kappa B complex. The results also suggest that higher insulin sensitivity and lower levels of proinflammatory molecules occurred regardless of weight and epididymal adipose tissue loss.CONCLUSION:Resveratrol increases insulin action and reduces inflammatory molecules in the myocardium.

title: Effect of actions promoting healthy eating on students' lipid profile: A controlled trial

description: OBJECTIVE:To assess the effect of nutrition intervention actions on the lipid profile of children and adolescents enrolled in public elementary schools.METHODS:This nine-month, controlled, intervention study included 202 students aged 7 to 14 years attending two schools (intervention/control) located in a poor neighborhood of the municipality of Salvador, Bahia, Brazil. Actions were implemented in the intervention school to promote healthy eating habits, presented as "Ten steps to healthy eating". The effect of these actions was assessed by subjecting the students at baseline and end of the follow-up to biochemical, maturation, and anthropometric measurements and a produce intake survey. The dependent variables were the changes in the study biochemical parameters: total cholesterol, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol, and triglycerides. Analysis of covariance assessed the changes that occurred over the study period.RESULTS:The mean total cholesterol, low-density lipoprotein-cholesterol, and triglycerides of the intervention students decreased 13.18 mg/dL (p=0.001), 7.41 mg/dL (p=0.038), and 12.37 mg/dL (p=0.029), respectively, compared with the control students.CONCLUSION:Actions of this nature have a positive impact on lipid profile. This study adds to those that use effective and viable public health strategies implementable at the primary care level.

title: Household food availability in Pelotas, Brazil: An approach to assess the obesogenic environment

description: OBJECTIVE:To identify household food availability according to socioeconomic and demographic factors.METHODS:A cross-sectional, population-based study was carried out in the city of Pelotas, Southern Brazil to determine household food availability in the 30 days that preceded the interview. Availability was considered high when food was "always" or "usually" available at home. The independent variables were: age and education level of the household head, number of household members, presence of children or adolescents, National Wealth Score, and family income.RESULTS:Data were collected from 1,555 households. A high availability of fruits and vegetables (80%) was more prevalent than that of soft drinks, processed meats, and sweets (40%). Whole grains and frozen foods were never available in half of the households. High-sugar and high-fat foods were positively related and fruits and whole grains were negatively related to the presence of children or adolescents in the household. National Wealth Score, family income, and age and education level of the household head were associated with household food availability.CONCLUSION:Socioeconomic factors and demographic characteristics were associated with household food availability. High household availability of fruits and vegetables, together with sweets, processed meats, and soft drinks suggests the complex eating practices of a household, impairing classifying the environment as obesogenic.

title: School Gardens in the Distrito Federal, Brazil

description: OBJECTIVE:The aim of the present study was to identify experiences with gardens in public schools in the Distrito Federal, Brazil, and to analyze factors involved in their use to promote healthy eating habits.METHODS:This is an analytical cross-sectional study with data collection in two phases: (1) telephone contact with all public schools in the Distrito Federal; (2) interviews conducted with a sample of schools with a garden (n=105).RESULTS:Of the 582 schools in the Distrito Federal, 453 (77.8%) participated in phase 1 and 37.7% of these had a garden. Rural schools had a higher prevalence of gardens (p=0.003). Among the schools which had no garden, 75.2% (n=212) had interest in creating one. The main reason for the deactivation of gardens was a lack of manpower to maintain them. The main reason for creating a garden was to supplement school food (56.2%). The garden was used as an educational space to promote healthy eating habits by 60.8% of the schools.CONCLUSION:An expressive percentage of schools with gardens (37.7%) was identified in the Distrito Federal. A number of factors were associated with the presence of a garden, including the location and size of the school, as well as the level of education. A significant percentage of schools reported using the garden as a space to promote healthy eating habits. This result must be refined by assessing the use and impact of gardens as a tool to promote healthy eating habits in the school community.

title: Nutritional adequacy of meals offered and consumed by soldiers of the Brazilian Army

description: OBJECTIVE:The purpose of this research is to evaluate the nutritional adequacy of meals served and consumed by soldiers in a construction unit (army and civil employees) of the Brazilian Army Construction.METHODS:Body mass index, fat percentage (bioimpedance) and the physical activity level were evaluated. Furthermore, the nutritional evaluation of meals offered and consumed by soldiers was evaluated, in relation to the macronutrients, sodium, fibers and total energetic value.RESULTS:Through the results, we verified that 76% of the soldiers were eutrophic, and that the population's energetic requirement was approximately 3.600 kcal. We verified that the energetic consumption of this population was below the required value (3.200 kcal) and with inadequacy regarding the distribution of macronutrients: percentage of carbohydrates above the recommended one, percentage of lipid below the minimum value recommended and percentage of proteins within the recommendation. Moreover, the amount of fibers was in accordance to the standards; however, there was an excessive amount of sodium, which may put this population in danger.CONCLUSION:We concluded that it is necessary to improve the quality of the meals offered in relation to the nutritional aspect, by promoting the adequacy to the soldiers' needs. Other types of quality were not studied, but they are important when evaluating acceptability of meals.

title: Incidence of overweight/obesity in preschool children during a two-year follow-up

description: OBJECTIVE:To analyze the incidence of overweight/obesity and associated factors in children aged six years or less during a two-year follow-up.METHODS:This longitudinal cohort study followed 242 preschoolers from Florianópolis, Santa Catarina, from 2008 to 2010. The outcome was overweight/obesity (Z-score &gt;+2) measured by accumulated incidence. The Chi-square test measured the differences between the study factors. The association between overweight/obesity and associated factors was analyzed by adjusted and crude rate ratios.RESULTS:Nine (4.00%) of the 222 non-overweight/obese children in 2008 were overweight/obese in 2010, indicating an accumulated incidence of overweight/obesity of 4.05% (1.4-6.7). The study accumulated incidence of overweight/obesity was 20.25/year/1000, similar to the incidence density of 20.65/year/1000.CONCLUSION:After adjustment, none of the study factors were associated with overweight/obesity. However, the lack of studies that investigate the incidence of overweight and obesity in preschoolers calls for longitudinal studies with larger samples that analyze not only the incidence of overweight/obesity but also other factors, such as the influence of parents' nutritional status on their offspring's nutritional status.

title: Organic foods from family farms in the National School Food Program: Perspectives of social actors from Santa Catarina, Brazil

description: OBJECTIVE:To analyze suggestions that facilitate the use of organic foods produced by family farms made by the social actors responsible for Santa Catarina's school meals.METHODS:This qualitative and exploratory study used an electronic questionnaire for surveying 293 municipalities in the state of Santa Catarina in 2010 and identified the percentage of organic school foods purchased from family farms. The social actors from 52 municipalities who were responsible for organic food acquisition were interviewed in person. Their suggestions were categorized and analyzed by content analysis.RESULTS:A total of 446 social actors made 684 suggestions categorized into four themes: Awareness strategies for the use of organic foods (n=286) were proposed by principals and dieticians, who emphasized the need of educating social actors and community and raising community awareness; Better Programa Nacional de Alimentação Escolarmanagement (n=148) was suggested by principals and family farmers, who wanted less bureaucracy and outsourcing, fewer taxes, and more management involvement; Better coordination between the demand and supply of organic foods (n=130) was suggested by principals, family farmers, and cooks because of logistic and supply problems; and Better management ofschool food production(n=120) was suggested by principals and cooks, who reported problems with the supply of specific foods, low organic food diversity, and lack of certification.CONCLUSION:For the social actors, the use of organic foods in the schools of Santa Catarina requires the education of those involved (technical support, educational strategies, and community awareness), government support, coordination between demand and supply, and better management of organic food production.
