title: Factors associated with serum lipids of adolescents from the Brazilian South

description: OBJECTIVE: This study analyzes factors associated with serum lipids in adolescents from southern Brazil. METHODS: This is a school-based cross-sectional study with a probabilistic sample composed of 660 adolescents aged 14 to 19 years from the city of Três de Maio, Rio Grande do Sul state, Brazil. The following independent variables were analyzed: body mass index; waist-to-height ratio; moderate to vigorous level of physical activity; sedentary behaviour; lipid, total saturated fatty acid, cholesterol, sodium, and fiber intakes; smoking; and alcohol abuse. Linear regression analysis tested the association between the independent variables and total cholesterol and high density lipoprotein-cholesterol. RESULTS: Body mass index was directly associated with total cholesterol (β=0.96, p=0.001) and reversely associated with high density lipoprotein-cholesterol (β=-0.45, p&lt;0.001). CONCLUSION: High body mass index may have a negative impact on the lipid profile of adolescents. Thus, monitoring nutritional status is important to prevent and control dyslipidemia in adolescents. We suggest multidisciplinary and intersectoral actions that encourage teenagers to acquire a healthy lifestyle, with emphasis on the adoption of an active lifestyle and balanced diet.

title: Clustering of physical inactivity and low fruit and vegetables intake and associated factors in young adults

description: OBJECTIVE: To investigate the cluster of physical inactivity and low fruit and vegetable intake and the associated factors in university students. METHODS: This cross-sectional study included a representative sample (n=717) of Universidade Federal Rural de Pernambuco students. Low fruit and vegetable intake was defined as an intake of less than five servings a day and physical inactivity was defined as exercising less than 150 minutes a week. The independent variables were gender, age, socioeconomic status, school year, shift, and study time. Clustering was determined by comparing the observed prevalence with the expected prevalence for all possible risk-factor combinations. Logistic regression analysis, performed by the software Statistical Package for the Social Sciences 17.0 with a significance level of 5% (p&lt;0.05), considered the presence of both risk behaviors adjusted to the independent variables. RESULTS: The prevalence of low fruit and vegetable intake was 81.7% (CI95%=78.1-84.3) and of physical inactivity was 65.8% (CI95%=62.2-69.4). Most students (58.6%, CI95%=55.3-62.2) were exposed to both risk factors simultaneously, while 11.0% (CI95%=8.9-13.5) were exposed to neither. Full-time students have a risk 1.45 times greater of simultaneous exposure. Juniors and seniors are, respectively, 1.88 and 2.80 times more likely to present both risk behaviors. CONCLUSION: Although complex, the behaviors are modifiable, and both the healthy and the unhealthy behaviors tend to cluster. The implementation of an intervention that targets both risk behaviors is needed. Different strategies can be used, such as providing areas for physical activity and for learning about healthy and risk behaviors.

title: Impact assessment of an intervention on the consumption of fruits and vegetables by students and teachers

description: OBJECTIVE: To evaluate the impact of an intervention that promoted the consumption of fruits and vegetables on the intake of these products by students and teachers in Rio de Janeiro (RJ), Brazil. METHODS: This is a one-group pretest-posttest study of students and teachers from elementary public schools in Rio de Janeiro. The intervention included a training course for promoting healthy eating; distribution of educational materials; and holding of a one-day health fair. We assessed the activities that had been carried out, teachers' habitual fruits and vegetables intake, students' fruits and vegetables intake at school, and intervention-related issues. RESULTS: Before the intervention, 65.1% of the students consumed the school lunch and most (&gt;79.4%) accepted and consumed the fruits and vegetables served. Most teachers (&gt;75.0%) consumed fruits and other vegetables regularly, but only 36.4% consumed leaf vegetables regularly. The intervention was implemented only moderately (52.7%) but was well accepted by the teachers. The students of schools that implemented the intervention more extensively showed better acceptance of vegetables (p=0.009). Teachers' fruits and vegetables intake did not change. CONCLUSION: Students' fruits and vegetables intake changed modestly. This study contributes to the design of intervention studies for Brazilian schools because it coordinated the National School Food Program with educational activities.

title: Diversity of eating patterns in older adults: A new scenario?

description: OBJECTIVE: To identify eating patterns and their distribution in a representative sample of older adults from the municipality of Botucatu, São Paulo, Brazil. METHODS: This cross-sectional study used food frequency and sociodemographic questionnaires to collect the respective data from 355 older users, selected by stratified sampling, of Botucatu's primary health care units from March to June 2011. Principal component analysis extracted six eating patterns. Individual food intake scores were divided into tertiles, classifying individual adherence to each eating pattern as low, moderate, or high, to measure the relationship between adherence tertiles and sociodemographic variables. RESULTS: Six eating patterns were identified and named as follows: healthy foods; snacks and weekend meals; fruits; light and whole foods; soft diet; and traditional diet. Individuals with elementary school adhered highly to the patterns 'healthy foods' and 'fruits'. On the other hand, men and individuals with the highest education levels adhered highly to the pattern 'snacks and weekend meal'. Females adhered more often to the patterns 'light and whole foods' and 'soft diet'. The pattern 'soft diet' was also preferred by the oldest subgroup. CONCLUSION: The study population presented a diversity of eating patterns influenced by sociodemographic characteristics.

title: Factors associated with exclusive breastfeeding in the Legal Amazon and Northeast regions, Brazil, 2010

description: OBJECTIVE: The objective of this study was to identify the factors associated with exclusive breastfeeding in children aged less than six months from the Brazilian Legal Amazon and Northeast regions. METHODS: The study used data from a survey that assessed prenatal and infant (&lt;1 year) care in 2010. Sociodemographic, prenatal, delivery, and puerperium care factors with p&lt;0.05 in multivariate analysis were associated with exclusive breastfeeding. RESULTS: For both regions, the prevalence of exclusive breastfeeding decreased with age, which was the main variable associated with early weaning. In the Legal Amazon, exclusive breastfeeding prevailed among: mothers aged 35 years or more; mothers living in state capitals; and mothers who breastfed on the first hour of life. In the Northeast, the probability of exclusive breastfeeding was greater for mothers aged 35 years or more. CONCLUSION: The factors associated with exclusive breastfeeding were child's and mother's age in both regions; and residence location and breastfeeding in the first hour of life in the Legal Amazon, suggesting the need of differentiated strategies for the promotion of exclusive breastfeeding.

title: Effect of fatty Amazon fish consumption on lipid metabolism

description: OBJECTIVE: The present study aimed to evaluate the effect of feeding diets enriched with fatty fish from the Amazon basin on lipid metabolism. METHODS: Male Wistar rats were divided into four groups: control group treated with commercial chow; Mapará group was fed diet enriched with Hypophthalmus edentatus; Matrinxã group was fed diet enriched with Brycon spp.; and, Tambaqui group was fed diet enriched with Colossoma macropomum. Rats with approximately 240g±0.60 of body weight were fed ad libitum for 30 days, and then were sacrificed for collection of whole blood and tissues. RESULTS: The groups treated with enriched diets showed a significant reduction in body mass and lipogenesis in the epididymal and retroperitoneal adipose tissues and carcass when compared with the control group. However, lipogenesis in the liver showed an increase in Matrinxã group compared with the others groups. The levels of serum triglycerides in the treated groups with Amazonian fish were significantly lower than those of the control group. Moreover, total cholesterol concentration only decreased in the group Matrinxã. High Density Lipoprotein cholesterol levels increased significantly in the Mapará and Tambaqui compared with control group and Matrinxã group. The insulin and leptin levels increased significantly in all treatment groups. CONCLUSION: This study demonstrated that diets enriched with fatty fish from the Amazon basin changed the lipid metabolism by reducing serum triglycerides and increasing high density lipoprotein-cholesterol in rats fed with diets enriched with Mapará, Matrinxã, and Tambaqui.

title: Research potential of food and nutrition in the Family Health Strategy: A structured review

description: OBJECTIVE: Determine the profile of research groups and publications with food and nutrition-related actions promoted by the Family Health Strategy in Brazil since 1994. METHODS: Two procedures were used: structured review and research group search. The former searched the databases Web of Science, Medline, Lilacs, SciELO and Embase, and followed the principles that guide systematic reviews in the Cochrane Collaboration. The references of the selected articles were also consulted. The research groups were searched in the Research Group Directory of the National Council for Scientific and Technological Development. RESULTS: A total of 54 articles published between 2002 and 2012 in 20 different journals were identified. Ten of these were retrieved from the references section of other articles. Focusing mostly on children from the Southeast region, these studies were coordinated by dieticians, nurses, and physicians. Diabetes Mellitus, high blood pressure, and breastfeeding were the most common topics (n=23). The quantitative methodology was employed by 42 articles, most about diagnoses. Only five research groups studied the Family Health Strategy, despite the growing number of studies in the area over the years. CONCLUSION: Despite the growing scientific production, the findings of this structured review indicate that few studies focused on food and nutrition in the Family Health Strategy, probably because of the existence of few research groups in the country. More comprehensive and consistent studies on the topic are needed.

title: Acute caffeine intake lowers glycemia before and after acute physical exercise in diabetic rats

description: OBJECTIVE:The present study investigated the effects of caffeine supplementation combined with acute physical exercise on the glycemic response of diabetic rats.METHODS:Thirty-two 60-day-old rats with a mean weight of 238±3 g were divided into four groups: control, control caffeine, diabetes, and diabetes/caffeine. Diabetes was induced by 60 mg/kg of streptozotocin intraperitoneally. The control groups received an acute dose of caffeine (6 mg) or saline 60 minutes before exercise. The animals were then forced to swim for 60 minutes carrying a ballast weighing 6% of their body weight, producing lactacidemia compatible with the maximum lactate production during the steady state (5.5 mmol/L). After the acute exercise session, the animals were sacrificed and their blood collected for glucose analysis. The cardiovascular responses were measured before and after supplementation by tail cuff plethysmography. The one-way Analysis of Variance (Anova) was realized with post hoc of Student-Newman-Keuls to analyse the statistical differences between the supplementations, considering p&lt;0.05.RESULTS:Caffeine at a dose of 6 mg/kg did not change the cardiovascular responses. However, compared with the control groups, caffeine reduced the blood glucose (42%, p&lt;0.05) of diabetic rats after 60 minutes of exercise.CONCLUSION:Acute caffeine ingestion together with exercise can increase glucose uptake without changing cardiovascular responses in animal models.
