Aplicação da técnica de grupo focal em pesquisa da Rede-SANS sobre as ações de alimentação e nutrição na atenção básica em saúde

Focus groups are seen as important tools in qualitative research for evaluating projects aimed at articulating social networks and movements. Six focus groups were held as one of the stages in research as part of the Food Safety and Sustainable Nutrition Project (SANS). This social network articulates the academic world with social movements and government in defense of the human right to suitable nutrition. This report is aimed at discussing the experience of applying focus groups to the investigation of perceptions by health professionals of activities related to food and nutrition in basic health care. These groups made it possible to bring together 52 professionals from 13 municipalities in the State of São Paulo, Brazil, and they exchanged experiences and debated issues related to food safety in the area of health care. The group discussions identified eating, nutrition vigilance and intersectoriality as emerging topics. The focus group technique proved to be a suitable tool for investigating the topic quickly and in depth, with a large number of professionals working in different contexts. In fact, the discussions went beyond the objectives of the research, since the group work made it possible to strengthen the process of articulation carried out by a network that promoting local measures in food safety and sustainable nutrition.

Improvements of nutrition behavior fitness and body fatness with a short-term after school intervention program

The prevalence of childhood obesity has been increasing worldwide and lifestyle changes are the most important strategies in managing this prevalence. This study aimed to describe the intervention effects of nutrition and physical activities offered as an after school short-term on outcomes of healthy nutrition practices, fitness and lowering fatness. This quasi-experimental study was conducted with a convenience sample of 59 caucasian children, aged 7.7 ± 1.4 years old (52.5% girls) registered on a private school of a middle-size town located in Sao Paulo State, Brazil. The school-based 12-week intervention consisted of 2 weekly 60 minutes section, during 3 months, including a nutritional education and a physical activity curriculum. Anthropometric data was measured for all children at baseline and after 12 weeks. All parents were contacted and requested to complete questionnaire about child’s eating behavior at baseline and after the 12-week program. After the intervention, children showed an increasing in the intake of fruits (64.3%), vegetables (61.9%), and water (52.0%). Overall, 83.3% of the children changed eating behavior according to the questionnaire responded by the parents. Waist circumference was significantly lower and abdominal strength improved after participating in the intervention program. Mean height and weight were significantly higher in boys and girls after a 12-week intervention. Although mean values of BMI remained the same after the intervention it was observed a decreasing in the prevalence of obesity among the children. Thus our study showed that a school-based intervention program focused on nutritional education and physical activity program promoted waist circumference reduction and decreased obesity without affecting the height growth along with improved fitness and healthy eating behavior. This intervention program would be feasible and replicable in others schools around the country.

Sewage sludge levels on the development and nutrition of sunflower plants

This study aimed to evaluate the effect of substituting chemical nitrogen (N) fertilization for equivalent N levels from sewage sludge of Wastewater Treatment Plant (WTP) on sunflower plant development. Nutrient levels in physiologically mature leaves and seeds, besides nutrient exportation during a 130-day assay, were also assessed. The experiment was carried out in 100 m(2) permanent plots at Sao Manuel Farm, which belongs to School of Agronomical Sciences, São Paulo State University-UNESP, Botncatu, São Paulo State, Brazil. The farm is located in the municipality of Sao Manuel, São Paulo State. Experimental design was in randomized blocks including 5 treatments and 5 replicates. Treatments were: T1 - chemical N fertilization according to the recommendation for the culture; T2 - 50% N from sewage sludge and 50% N from chemical fertilization; T3 - 100% N from sewage sludge; T4 - 150% N from sewage sludge; T5 - 200% N from sewage sludge. For all treatments, equal amounts of P and K fertilization were applied. Treatments differed for plant height from 21 to 64 days, stern diameter from 28 to 57 days, and leaf number from 21 to 38 days. Seed nutrient levels slightly varied; however, the quantities of exported N, P, Mg, Fe and Zn varied as sewage sludge levels increased.

Occurrence of coagulase-positive Staphylococcus in various food products commercialized in Botucatu, SP, Brazil and detection of toxins from food and isolated strains

The aim of this work was to assess the microbiological quality of commercialized desserts, sandwiches and finger food in Botucatu, SP, for human consumption. A total of 172 food samples were analyzed for fecal coliforms and coagulase-positive Staphylococcus and 69 (40.1%) were in disagreement with the standards established by Decree No. 12 (Brazilian Food Sanitation Standard, 2001). Coagulase-positive Staplylococcus was isolated from 26 (15.1%) samples. Toxins were not isolated directly from foods but 27 (54%) coagulase-positive Staphylococcus strains were enterotoxigenic, and toxin type C was the most frequently detected. These results suggest that these products may act as an important vehicle of transmission for well-established pathogens. (c) 2006 Elsevier Ltd. All rights reserved.

Theoretical estimates of consumable food and probability of acquiring food in larvae of Chrysomya putoria (Diptera: Calliphoridae)

An indirect estimate of consumable food and probability of acquiring food in a blowfly species, Chrysomya putoria, is presented. This alternative procedure combines three distinct models to estimate consumable food in the context of the exploitative competition experienced by immature individuals in blowfly populations. The relevant parameters are derived from data for pupal weight and survival and estimates of density-independent larval mortality in twenty different larval densities. As part of this procedure, the probability of acquiring food per unit of time and the time taken to exhaust the food supply are also calculated. The procedure employed here may be valuable for estimations in insects whose immature stages develop inside the food substrate, where it is difficult to partial out confounding effects such as separation of faeces. This procedure also has the advantage of taking into account the population dynamics of immatures living under crowded conditions, which are particularly characteristic of blowflies and other insects as well.

Solids rheology for dehydrated food and biological materials

Mechanical properties of food products and biological materials are greatly affected by the drying process and are considered one of the most important quality attributes of dehydrated products. The aim of this work was to review theoretical principles and mathematical modeling, analyzing the measurement techniques and major experimental results that exist in the literature about rheological properties of dehydrated foods and biological materials. Different methods of measuring rheological parameters (fundamental and empiric or imitative) are discussed and major experimental results, as well as the rheological models used in their analysis, published in recent years are presented.

Analysis of pesticides in food and environmental samples by enzyme-linked immunosorbent assays

Enzyme-linked immunosorbent assays (ELISAs) are the most extensively studied types of immunoassay and their application in pesticide residue monitoring is an area with enormous potential for growth. In comparison with classical analytical methods, ELISA methods offer the possibility of highly sensitive, relatively rapid, and cost-effective measurements. This review introduces the general ELISA formats used, focusing on their use in pesticide analysis. Identifying and studying the effects of interferences in immunoassays is an active area of research and we discuss the matrix effects observed in several studies involving e.g. food, crop and environmental samples. The procedures to eliminate the matrix interferences are briefly discussed. (C) 1998 Elsevier B.V. B.V.
