Influence of intervention on the menu's nutritional and sensory qualities and on the food waste of children's education center / Influência da intervenção na qualidade nutricional e sensorial de cardápios e resto-ingestão de centro de educação infantil

Abstract The aim was to evaluate the influence of an intervention on the nutritional and sensory quality of the menus and on the food waste of a Children's Educational Center. It is a quasi-experimental study that used the Qualitative Assessment of the Menu Preparations method and performed the waste-ingestion quantities and clean leftovers. The intervention was characterized by the inclusion of new recipes and adequacy of portions according to recommendations for the children's age group. Data were analyzed using the Mann Whitney test with a significance level of p < 0.05. The intervention resulted in a reduction in the occurrence of the side dish supply, color monotony, presence of sweets, presence of fried foods, sweets associated with fried foods, and repetition of the main dish cooking technique. In addition, there was a significant reduction in the average quantities of waste-ingestion/child (from 69.02 ± 11.87g to 37.06 ± 15.57g), clean leftovers /child (from 161.47 ± 44.12g to 35.23 ± 33.73 g) and clean leftovers percentage (from 39.56 ± 7.96 to 21.01 ± 17.15). The positive influence of intervention reinforces the importance of adjustments in recipes and portioning of preparations to meet the nutritional recommendations and to control food waste.

Resumo O objetivo do estudo foi avaliar a influência de uma intervenção na qualidade dos cardápios e no desperdício de alimentos em um Centro de Educação Infantil. Trata-se de um estudo quase-experimental que utilizou o método de Avaliação Qualitativa de Preparações de Cardápios e avaliou quantidades de resto-ingestão e sobra limpa. A intervenção foi caracterizada pela inclusão de receituários e adequação do porcionamento das preparações segundo recomendações para a faixa etária. Os dados foram analisados pelo teste de Mann Whitney, nível de significância de p < 0,05. A intervenção proporcionou redução na ocorrência de oferta de guarnição, monotonia de cores, presença de doce, presença de frituras e de doce associado a fritura e repetição da técnica de cocção do prato principal. Além disso, observou-se redução significativa nas quantidades médias de resto-ingestão/criança (de 69,02 ± 11,87g para 37,06 ± 15,57g), de sobra limpa/criança (de 161,47 ± 44,12g para 35,23 ± 33,73 g) e do percentual de sobra limpa (de 39,55 ± 7,96 para 21,01 ± 17,15). A influência positiva da intervenção reforça a importância de adequações nos receituários e no porcionamento, para o atendimento das recomendações nutricionais e controle do desperdício de alimentos no ambiente escolar.

Adequação nutricional e desperdício de alimentos em Centros de Educação Infantil / Nutritional adequacy and food waste in Early Childhood Education Centers

Resumo Analisar aspectos quantitativos e qualitativos da alimentação escolar constitui-se de etapa primordial para fazer do Programa Nacional de Alimentação Escolar (PNAE) um espaço efetivo para a promoção da alimentação saudável e formação de sujeitos de direitos. O objetivo deste estudo foi avaliar a adequação nutricional das refeições servidas e consumidas e quantificar o desperdício de alimentos em Centros de Educação Infantil de Maceió/AL. Foram analisadas por três dias não consecutivos, pelo método de pesagem direta, as refeições de 359 crianças (17 e 63 meses). O desperdício de alimentos foi determinado pelo índice de resto-ingestão e o valor nutricional das refeições servidas e consumidas foram comparadas com os valores de referência do PNAE para energia, carboidrato, proteína, lipídio, vitaminas A e C, ferro, cálcio, zinco, magnésio e fibra. Dos 85 alimentos/preparações presentes no cardápio, 58 (68%) apresentaram percentual de resto-ingestão, superior a 10%. As refeições servidas e consumidas atenderam aproximadamente 50% do recomendado para energia e macronutrientes. A diferença entre as médias dos nutrientes ofertados e consumidos foi estatisticamente significante (p < 0,05) para fibra, vitamina A, vitamina C, cálcio, ferro e zinco.

Abstract Analyzing quantitative and qualitative aspects of school meals represents the initial stage to ensure that the National School Food Program (PNAE) is an effective space for the promotion of healthy eating habits and establishing individual rights. The objective of this study was to evaluate the nutritional adequacy of meals served and consumed, as well as quantifying food waste in Child Daycare Centers in Maceió, in the state of Alagoas. All meals served and consumed by 359 children (aged 17 to 63 months) were analyzed by the direct weighing method for three non-consecutive days in all institutions. Food waste was determined by the leftover factor and the nutritional value of meals served and consumed was compared to the PNAE reference values regarding energy, carbohydrates, protein, lipids, vitamins A and C, iron, calcium, zinc, magnesium and fiber. Of the 85 meals/preparations featured on the menu, 58 (68%) revealed a high leftover percentage; in excess of 10%. The meals served and consumed met approximately 50% of the recommended energy and macronutrient values. The difference between the averages of the nutrients offered and consumed was statistically significant (p < 0.05) for fiber, vitamin A, vitamin C, calcium, iron and zinc.

Insulin therapy waste produced in the households of people with diabetes monitored in Primary Care / Los residuos de la terapia con insulina en las viviendas de personas con diabetes asistidas en atención primaria / Resíduos de insulinoterapia produzidos no domicílio de diabéticos acompanhados na Atenção Primária

ABSTRACT Objective: To analyze the insulin therapy waste disposal produced in the households of people with diabetes mellitus (DM). Method: Cross-sectional study with 105 Primary Care patients. Socio-demographic and clinical variables and insulin therapy practice were analyzed through the absolute and relative frequencies, Fisher's exact test and prevalence ratio (PR). Results: The association between types of insulin (60.0%), administered with a disposable syringe attached to a needle (80.9%), and a high percentage of reuse and disposal in normal household waste (57.1%) stood out. The professionals who most frequently provided guidance to people with diabetes were the nurses. Patients who had received instructions about disposal were 21 times more likely to dispose of waste properly than those who had not (PR 21.5; P < 0.0001). Age, gender, skin color, education, marital status, occupational status and type of DM did not interfere in the disposal (P > 0.05). Conclusion: People with diabetes served in Primary Health Care require guidance and material resources to carry out the appropriate disposal of insulin therapy waste.

RESUMEN Objetivo: Analizar la eliminación de los residuos de la terapia con insulina en las viviendas de personas con diabetes mellitus (DM). Método: Estudio transversal, del cual participaron 105 pacientes asistidos en atención primaria. Se analizaron las variables sociodemográficas, clínicas y la administración de la terapia con insulina a través de las frecuencias absoluta y relativa, la prueba exacta de Fisher y la razón de prevalencias (RP). Resultados: Se destacaron la asociación entre insulinas (60,0%) aplicadas con jeringuillas desechables pegadas a la aguja (80,9%), su elevado porcentaje de reutilización y su eliminación en la basura doméstica común (57,1%). Los enfermeros fueron los profesionales que más orientaron a los pacientes con diabetes. Los pacientes orientados presentaron más de 21 posibilidades de eliminar correctamente los residuos que los que no recibieron orientación (RP 21,5; p<0,0001). La edad, sexo, etnia, nivel de instrucción, estado civil, situación laboral y tipo de DM no influyeron en los resultados para la eliminación de estos residuos (p>0,05). Conclusión: Las personas con diabetes asistidas en atención primaria carecen de recomendaciones y recursos materiales que les informen la correcta eliminación de los residuos de la terapia con insulina.

Hospital waste: can we reduce the environmental impact of a large university hospital?

Introduction: As technology advances, society must reflect on the destination of materials which are no longer needed. Hospital waste requires special attention due to the associated risk of disease transmission and biological accidents. Also, it tends to increase proportionally to the economic development and is associated with increased use of disposable material. The purpose of this study is to analyze the management of hospital waste at the Hospital de Clínicas de Porto Alegre (HCPA) and to evaluate the effectiveness and feasibility of the measures adopted by the institution to mitigate the impact of its waste on the environment. Methods: Observational study with field research. Hospital waste management is divided into generation, disposal, storage and final destination. Results: Between 2010 and 2015, the HCPA produced 21.4 tons of biological and sharps waste, 23,000 liters of chemical waste and 113,9 tons of solid waste per month. The main improvements include the implementation of a inspection of the hospital's waste bins every 2 months, a reduction from 29.42% to 2.79% in the rate of inappropriate disposal of hazardous waste, a 313% increase in investments in staff training, the expansion and adaptation of external areas for temporary storage of hospital waste and the collection of more than 1 ton of waste generated by the local community (sharps, X-ray films, kitchen oil, batteries), as well as the establishment of contracts which will guarantee the appropriate treatment of all types of health care waste. Conclusions: These results demonstrate that mitigating the impact of hospital waste on the environment is possible and should encourage the adoption of similar measures at other institutions (AU)

[Evaluating the quantity and composition of solid waste generated in Kashan during 2009-10]

Solid waste management is considered to be one of the most immediate and serious environmental problems confronting urban governments in developing countries. Qualitative and quantitative variety of waste composition, uncontrolled urban development and the lack of appropriate waste management technology cause particular problems that solving them needs a careful study and the coordination of science and experience in the form of a proper management. This descriptive study was carried out on solid wastes generated in Kashan over a limited timeframe of 12 months during 2009-10. One sample was randomly taken per month according to the standard instruction and subsequently the physical analysis of it was performed. The average daily waste generation rate in Kashan is 185 tons, of which 75.5% are putrescible materials. The average daily waste generation is tantamount to 638 g/capita while the average density of the waste 194 kg/m[3] at transfer station. The most frequent metal measured in the leachate solid waste was iron. According to the results high percentages of solid wastes in Kashan were allocated to plastic and corruptible materials, and then the paper and cardboard. Considering that the prevention of adverse environmental effects of solid waste is a priority and applying proper management techniques can help to achieve this, public education for the waste separation at the source, waste reduction and subsequently reduction of the leachate volume as well as the proper manner of recycling, collection and disposal of the waste are recommended

Digestibility of fish silage and fish meal by nile tilapia [oreochromis niioticus]

Two digestibility trials were conducted. The first trial determined the digestibility coefficients of the local fish meal [low quality], fish meal [medium quality], fish silage made from fish processing waste and fish silage made from unusable fish for human consumption which were fed as single ingredients for 5 days. The apparent digestibility coefficient of protein, lipid, calcium and phosphorus were higher for the fish silage [which was made from unusable fish for human consumption] followed by the other fish products. The second trial determined the digestibility coefficient of four diets, whereas, each diet contained one source of fish silage made from unusable fish for human consumption and fish silage made from fish processing waste. The present data also indicated that the nutritional value of fish silage was improved by storing the ingredients at -5C prior to ensiling, and the diets done using these silages contained more intact protein and less free amino acids than diets done using conventional fish products
