Alcohol advertising in sport and non-sport TV in Australia, during children's viewing times

Estimate the amount of alcohol advertising in sport vs. non-sport programming in Australian free-to-air TV and identify children's viewing audience composition at different times of the day. Alcohol advertising and TV viewing audience data were purchased for free-to-air sport and non-sport TV in Australia for 2012. We counted alcohol advertisements in sport and non-sport TV in daytime (6 am-8.29 pm) and evening periods (8.30 pm-11.59 pm) and estimated viewing audiences for children and young adults (0-4 years, 5-13 years, 14-17 years, 18-29 years). During the daytime, most of the alcohol advertising (87%) was on sport TV. In the evening, most alcohol advertising (86%) was in non-sport TV. There was little difference in the mean number of children (0-17 years) viewing TV in the evening (N = 273,989), compared with the daytime (N = 235,233). In programs containing alcohol advertising, sport TV had a greater mean number of alcohol adverts per hour (mean 1.74, SD = 1.1) than non-sport TV (mean 1.35, SD = .94). Alcohol advertising during the daytime, when large numbers of children are watching TV, is predominantly in free-to-air sport TV. By permitting day-time advertising in sport programs and in any programs from 8.30 pm when many children are still watching TV, current regulations are not protecting children from exposure to alcohol advertising.

What influences urban Indian secondary school students' food consumption? - a qualitative study

Indian adolescents' over reliance on foods such as nutrient-poor snacks, sugar-sweetened beverages and take-away foods puts them at significant risk of obesity and several diet-related chronic diseases. Therefore, the factors that influence their dietary behaviours need to be better understood in order to develop effective nutrition promotion strategies. The purpose of this qualitative inquiry was to investigate adolescents', parents', teachers', and school principals' perceptions of the main influences on adolescent eating behaviours. Fifteen adolescents aged 14-15 years, 15 parents, 12 teachers and 10 principals from 10 private English-speaking schools in Kolkata, India, participated in semi-structured interviews. The digitally-recorded conversations were transcribed verbatim and analysed thematically. The 52 interviews revealed a number of factors that may influence adolescents' eating habits including parent and peer influences, home and school food environments, and the mass media. Emerging evidence suggests that future health and nutrition promotion interventions need to target the different influences on Indian teenagers' food consumption.

Effect of flour processing on the quality characteristics of a soy-based beverage

Four treatments (roasting, germination, autoclaving and an application of 0.5% EDTA+0.5% sodium hydroxide) were used to reduce the beany flavour of soya beans to produce a soy-based beverage. While germination significantly increased the protein level as compared to the other treatments, the maximum reduction of the beany flavour was achieved by the 0.5% EDTA+0.5% sodium hydroxide application. The soya beans that underwent this treatment were used during the second phase for optimized beverage formulation. During the second phase, a beverage was prepared according to different formulations and analysed for chemical composition and total viable count during a two-month storage period. During storage, the beverage samples exhibited variations in several parameters. The acidity, reducing sugars and total sugars increased, while the ascorbic acid, total soluble solids and pH decreased. Overall, chemical and microbial analyses showed the stability of the product during the storage period.

Mediating effects of dietary intake on associations of TV viewing, body mass index and metabolic syndrome in adolescents

OBJECTIVE: Evidence suggests that TV viewing is associated with body mass index (BMI) and metabolic syndrome (MetS) in adolescents. However, it is unclear whether dietary intake mediates these relationships.

METHODS: A cross-sectional analysis was conducted in adolescents (12-19 years) participating in the 2003-2006 United States National Health and Nutrition Examination Survey. BMI z scores (zBMI) (n = 3,161) and MetS (n = 1,379) were calculated using age- and sex-specific criteria for adolescents. TV viewing (h/day) was measured via a self-reported questionnaire, and dietary intake was assessed using two 24-h recalls. Using the MacKinnon method, a series of mediation analyses were conducted examining five dietary mediators (total energy intake, fruit and vegetable intake, discretionary snacks, sugar-sweetened beverages and diet quality) of the relationships between TV viewing and zBMI and MetS.

RESULTS: Small positive relationships were observed between TV viewing and zBMI (β = 0.99, p < 0.001) and TV viewing and MetS (OR = 1.18, p = 0.046). No dietary element appeared to mediate the relationship between TV viewing and zBMI. However, sugar-sweetened beverage consumption and fruit and vegetable intake partially mediated the relationship between TV viewing and MetS, explaining 8.7% and 4.1% of the relationship, respectively.

CONCLUSIONS: These findings highlight the complexity of the relationships between TV viewing, dietary intake and cardiometabolic health outcomes, and that TV viewing should remain a target for interventions.

L’objectif de modifier ou de contrôler son poids chez les adolescents : vecteur de promotion des saines habitudes de vie ou facteur de risque à la santé ?

L’objectif de modifier son poids est associé à certains comportements potentiellement dangereux, mais ses retombées sur les saines habitudes de vie des adolescents sont peu connues. L’objectif du mémoire est de quantifier les associations entre l’objectif relatif au contrôle du poids et la consommation de fruits et légumes, de boissons sucrées et d’aliments de restauration rapide, la prise du déjeuner et la pratique d’activité physique. Des régressions logistiques ont été effectuées sur les données de l’Enquête québécoise sur la santé des jeunes du secondaire 2010-2011. Respectivement, 25 %, 34 %, 12 % et 29 % des adolescents essayaient de perdre, maintenir, gagner du poids et ne rien faire à propos de leur poids. Chez les garçons et les filles, essayer de perdre du poids était associé à une probabilité plus faible de déjeuner quotidiennement (RC garçons = 0,72 ; 95%IC = 0,61 - 0,84, RC filles = 0,61 ; 95%IC = 0,56 -0,70) et chez les filles, cela était aussi associé à une probabilité plus élevée de consommer au moins cinq portions de fruits et légumes par jour (RC = 1,20 ; 95%IC = 1,04 - 1,37) et une probabilité plus faible de consommer des boissons sucrées quotidiennement (RC = 0,77 ; 95%IC = 0,66 - 0,90). Essayer de maintenir son poids et de gagner du poids étaient minimalement associés à une habitude plus délétère. L’objectif de contrôler son poids n’est donc pas strictement positif ou négatif. Il semble plus prudent de promouvoir directement les saines habitudes de vie plutôt que d’encourager l’adoption d’un objectif de contrôle du poids.

High-performance liquid chromatography (HPLC) and high-performance liquid chromatography mass spectrometry (HPLC/MS) for the analysis of date rape drugs

The drugs studied in this work have been reportedly used to commit drug-facilitated sexual assault (DFSA), commonly known as "date rape". Detection of the drugs was performed using high-performance liquid chromatography with ultraviolet detection (HPLC/UV) and identified with high performance-liquid chromatography mass spectrometry (HPLC/MS) using selected ion monitoring (SIM). The objective of this study was to develop a single HPLC method for the simultaneous detection, identification and quantitation of these drugs. The following drugs were simultaneously analyzed: Gamma-hydroxybutyrate (GHB), scopolamine, lysergic acid diethylamide, ketamine, flunitrazepam, and diphenhydramine. The results showed increased sensitivity with electrospray (ES) ionization versus atmospheric pressure chemical ionization (APCI) using HPLC/MS. HPLC/ES/MS was approximately six times more sensitive than HPLC/APCI/MS and about fifty times more sensitive than HPLC/UV. A limit of detection (LOD) of 100 ppb was achieved for drug analysis using this method. The average linear regression coefficient of correlation squared (r2) was 0.933 for HPLC/UV and 0.998 for HPLC/ES/MS. The detection limits achieved by this method allowed for the detection of drug dosages used in beverage tampering. This method can be used to screen beverages suspected of drug tampering. The results of this study demonstrated that solid phase microextraction (SPME) did not improve sensitivity as an extraction technique when compared to direct injections of the drug standards.

Burnout syndrome and alcohol consumption in prison employees

Objective: The aims of this study were to estimate the association between an at‑risk drinking pattern and sociodemographic variables, and to compare the mean scores of the factors associated with the Burnout Syndrome, according to the alcohol consumption pattern in staff members from two Brazilian prisons. Methods: A cross‑sectional study was developed with 339 participants (response rate = 63.8%). The instruments used were a sociodemographic questionnaire, the Alcohol Use Disorders Identification Test (AUDIT), and the Maslach Burnout Inventory – General Survey (MBI‑GS). Results: The participants’ average age was 40.2 (SD = 8.8) years, and 81.0% were male. Among 78.5% of participants (95%CI 74.1 – 82.8) reported consuming alcoholic beverages. The prevalence of at‑risk drinking behavior in the sample was 22.4% (95%CI 18.0 – 26.9), and of the Burnout Syndrome was 14.6% (95%CI 10.8 – 18.4). We observed a significant association between at‑risk drinking behavior with gender, higher risk for men (OR = 7.32, p < 0.001), smoking, increased risk for smokers (OR = 2.77, p < 0.001), and religious practice, showing lower risks for religion practitioners (OR = 0.364, p < 0.001). We noticed significantly higher mean scores (p < 0.001) of emotional exhaustion and cynicism, and lower scores of professional achievement among individuals who reported consuming alcoholic beverages. Conclusion: Men who smoke were more likely to develop an at‑risk drinking pattern, while religion is presented as a protective factor. Individuals who consume alcohol were more affected by the different factors of the Burnout Syndrome.

Participation of portuguese manufacturing industry in global value chains

Portugal’s manufacturing sector has a significant importance both in national income and employment. As has been pointed out by several researchers, the traditional methods of analysis fail to grasp all the dimensions of economic competitiveness. This dissertation is then, at its core, an analysis of Portugal’s manufacturing industry in terms of the latter’s value added to production and impact to employment under the framework of global value chains. The current dissertation seeks to study in which way the Portuguese manufacturing industry, and its respective sectors, has a direct and indirect impact on the creation of value added and employment and how this impact can be measured. For development of this work the input-output approach for calculation of multipliers and the new framework proposed by Timmer et al. (2013) for calculation of GVC income and GVC jobs indicators were used, elaborated on the basis of the WIOD project dataset. Moreover, to illustrate the application of the provided methodology the Portuguese textile industry was used as an example. It was found that the changes in final demand of such sectors as Pulp, Paper, Printing and Publishing; Machinery, Nec and Textiles and Textile Products would have a larger impact on generated value added than other manufacturing sectors. At the same time, employment created by the changes in final demand would be more impacted by such sectors as Food, Beverages and Tobacco; Wood and Products of Wood and Cork and Textiles and Textile Products. In this regard, the number of low-skilled workers in Portugal seems to be more effected by changes in final demand, than those occupied by higher -skilled individuals. Moreover, it was found that the distribution of GVC income and GVC jobs for the Portuguese manufacturing industry shares a similar outlook. However, upon closer inspection of GVC labour distribution by skill levels there seems to exist a general progression in which low-skilled jobs requirements are met by local resources, while the need for higher skilled jobs require a greater “off-shoring” of work The results obtained through calculations of presented multipliers provide a powerful tool for policy makers in strategic planning of development of national economy. Using the provided methodology and obtained results, a government and supranational organizations could define which industry would have the greatest impact for an additional unit of output generated through the economy, and thus define the sectors for further investments.

New trends in food science: the use of nutraceuticals as an antiinflammatory therapeutic tool in exercise

Prolonged high-intensity training seems to result in increased systemic inflammation, which might explain muscle injury, delayed onset muscle soreness, and overtraining syndrome in athletes. Furthermore, an impaired immune function caused by strenuous exercise leads to the development of upper respiratory tract infections in athletes. Nutraceuticals might help counteract these performance-lowering effects. The use of nanotechnology is an interesting alternative to supply athletes with nutraceuticals, as many of these substances are insoluble in water and are poorly absorbed in the digestive tract. The present chapter starts with a brief review of the effects of exercise on immunity, followed by an analysis on how nutraceuticals such as omega-3 fatty acids, glutamine, BCAAs, or phytochemicals can counteract negative effects of strenuous exercise in athletes. Finally, how nanostructured delivery systems can constitute a new trend in enhancing bioavailability and optimizing the action of nutraceuticals will be discussed, using the example of food beverages.

Erosão dentária na adolescência

Com o presente trabalho, pretende-se perceber qual a relação do estilo de vida, hábitos alimentares e doenças sistémicas dos adolescentes com a erosão dentária, e quais são as melhores formas de prevenção e tratamento. É na fase da adolescência que começa a haver uma maior preocupação com o corpo e que começam a surgir alguns extremos de consumo alimentar, que podem caracterizar-se em desordens alimentares afetando diretamente a saúde oral, podendo causar erosão dentária. É também na adolescência que a prática de atividade desportiva aumenta, podendo também ter impacto no desenvolvimento desta patologia. A erosão dentária começa com a desmineralização das camadas superficiais do esmalte, podendo evoluir para perda significativa da estrutura dentária. Os ácidos responsáveis pela erosão dentária podem ter origem extrínseca ou intrínseca. Enquanto os fatores extrínsecos estão relacionados com hábitos alimentares e estilo de vida, os fatores intrínsecos podem ser provocados por doenças sistémicas. O fator fundamental da prevenção da erosão dentária é a diminuição da frequência e da severidade do ataque ácido. No entanto, pela sua etiologia multifatorial, muitas vezes este controlo torna-se difícil. Em relação ao tratamento, existem diferentes opções dependendo do grau da lesão, mas um diagnóstico precoce é o fator chave neste processo. É importante referir que a monitorização e o controlo periódico do paciente deverão ser realizados com o objetivo de promover a sua saúde e prevenir o aparecimento de novas lesões.

Saccharomyces cerevisiae in the production of whisk(e)y

Whisky is a major global distilled spirit beverage. Whiskies are produced from cereal starches that are saccharified, fermented and distilled prior to spirit maturation. The strain of Saccharomyces cerevisiae employed in whisky fermentations is crucially important not only in terms of ethanol yields, but also for production of minor yeast metabolites which collectively contribute to development of spirit flavour and aroma characteristics. Distillers must therefore pay very careful attention to the strain of yeast exploited to ensure consistency of fermentation performance and spirit congener profiles. In the Scotch whisky industry, initiatives to address sustainability issues facing the industry (for example, reduced energy and water usage) have resulted in a growing awareness regarding criteria for selecting new distilling yeasts with improved efficiency. For example, there is now a desire for Scotch whisky distilling yeasts to perform under more challenging conditions such as high gravity wort fermentations. This article highlights the important roles of S. cerevisiae strains in whisky production and describes key fermentation performance attributes sought in distiller's yeast, such as high alcohol yields, stress tolerance and desirable congener profiles. We hope that the information herein will be useful for whisky producers and yeast suppliers in selecting new distilling strains of S. cerevisiae, and for the scientific community to stimulate further research in this area.

Antioxidant and angiotensin-converting enzyme inhibitory activity of eucalyptus camaldulensis and litsea glaucescens infusions fermented with Kombucha Consortium

Physicochemical properties, consumer acceptance, antioxidant and angiotensin-converting enzyme (ACE) inhibitory activities of infusions and fermented beverages of Eucalyptus camaldulensis and Litsea glaucescens were compared. Among physicochemical parameters, only the pH of fermented beverages decreased compared with the unfermented infusions. No relevant changes were reported in consumer preference between infusions and fermented beverages. Phenolic profi le measured by UPLC MS/MS analysis demonstrated signifi cant concentration changes of these compounds in plant infusions and fermented beverages. Fermentation induced a decrease in the concentration required to stabilize 50 % of DPPH radical (i.e. lower IC50). Additionally, it enhanced the antioxidant activity measured by the nitric oxide scavenging assay (14 % of E. camaldulensis and 49 % of L. glaucescens); whereas relevant improvements in the fermented beverage were not observed in the lipid oxidation assay compared with unfermented infusions. The same behaviour was observed in the inhibitory activity of ACE; however, both infusions and fermented beverages had lower IC50 than positive control (captopril). The present study demonstrated that fermentation has an infl uence on the concentration of phenolics and their potential bioactivity. E. camaldulensis and L. glaucescens can be considered as natural sources of biocompounds with antihypertensive potential used either as infusions or fermented beverages.

Estado nutricional y etapas de cambio comportamental frente a la actividad física niños y adolescentes de Bogotá, Colombia: Estudio FUPRECOL

Objetivo: El propósito del estudio fue relacionar la etapa en el cambio en el comportamiento frente a la actividad física y el estado nutricional en escolares entre 9 y 17 años de Bogotá- Colombia, pertenecientes al estudio FUPRECOL. Método: Se trata de un estudio transversal, en 6.606 niños y adolescentes entre 9 y 17 años, pertenecientes a 24 instituciones educativas, de Bogotá-Colombia. Se aplicó de manera auto-diligenciada el cuestionario de cambio de comportamiento en función a la intensión de realizar actividad física (CCC-Fuprecol) y se midió el peso y la estatura para determinar el estado nutricional con el índice de masa corporal (IMC). Resultados: El porcentaje de respuesta fue 94% y se consideraron válidos 6,606 registros, siendo 58.3 % (n=3.850) niñas con un promedio de edad de 12,7±2,3 años. En la población general, el 5,3 % de los escolares se encontraban en etapa de pre-contemplación, 31,8 % en contemplación, el 26,7 % en acción y el 36,2 % en etapa de mantenimiento. Al comparar la etapa de cambio con el estado nutricional por IMC, los escolares clasificados en obesidad mostraron mayor frecuencia de respuesta en la etapa de pre-contemplación, mientras que los escolares con peso saludable acusaron mayores porcentajes en la etapa de mantenimiento. Conclusión: En escolares de Bogotá, Colombia, se encontró una relación estadísticamente significativa entre a la intensión de realizar actividad con el estado nutricional medido con el IMC. Fomentar la promoción de la actividad física y monitorear el estado nutricional, deberá ser una prioridad en las agendas y políticas públicas dentro del ámbito escolar.
