A systematic review of environmental correlates of obesity-related dietary behaviors in youth

There is increasing interest in the role the environment plays in shaping the dietary behavior of youth, particularly in the context of obesity prevention. An overview of environmental factors associated with obesity-related dietary behaviors among youth is needed to inform the development of interventions. A systematic review of observational studies on environmental correlates of energy, fat, fruit/ vegetable, snack/fast food and soft drink intakes in children (4–12 years) and adolescents (13–18 years) was conducted. The results were summarized using the analysis grid for environments linked to obesity. The 58 papers reviewed mostly focused on sociocultural and economical–environmental factors at the household level. The most consistent associations were found between parental intake and children’s fat, fruit/vegetable intakes, parent and sibling intake with adolescent’s energy and fat intakes and parental education with adolescent’s fruit/ vegetable intake. A less consistent but positive association was found for availability and accessibility on children’s fruit/vegetable intake. Environmental factors are predominantly studied at the household level and focus on sociocultural and economic aspects. Most consistent associations were found for parental influences (parental intake and education).More studies examining environmental factors using longitudinal study designs and validated measures are needed for solid evidence to inform interventions.

Political information choices in a media saturated environment : credibility or convenience?

This thesis examines the ways in which citizens find out about socio-political issues. The project set out to discover how audience characteristics such as scepticism towards the media, gratifications sought, need for cognition and political interest influence information selection. While most previous information choice studies have focused on how individuals select from a narrow range of media types, this thesis considered a much wider sweep of the information landscape. This approach was taken to obtain an understanding of information choices in a more authentic context - in everyday life, people are not simply restricted to one or two news sources. Rather, they may obtain political information from a vast range of information sources, including media sources (e.g. radio, television, newspapers) and sources from beyond the media (eg. interpersonal sources, public speaking events, social networking websites). Thus, the study included both media and non-news media information sources. Data collection for the project consisted of a written, postal survey. The survey was administered to a probability sample in the greater Brisbane region, which is the third largest city in Australia. Data was collected during March and April 2008, approximately four months after the 2007 Australian Federal Election. Hence, the study was conducted in a non-election context. 585 usable surveys were obtained. In addition to measuring the attitudinal characteristics listed above, respondents were surveyed as to which information sources (eg. television shows, radio stations, websites and festivals) they usually use to find out about socio-political issues. Multiple linear regression analysis was conducted to explore patterns of influence between the audience characteristics and information consumption patterns. The results of this analysis indicated an apparent difference between the way citizens use news media sources and the way they use information sources from beyond the news media. In essence, it appears that non-news media information sources are used very deliberately to seek socio-political information, while media sources are used in a less purposeful way. If media use in a non-election context, such as that of the present study, is not primarily concerned with deliberate information seeking, media use must instead have other primary purposes, with political information acquisition as either a secondary driver, or a by-product of that primary purpose. It appears, then, that political information consumption in a media-saturated society is more about routine ‘practices’ than it is about ‘information seeking’. The suggestion that media use is no longer primarily concerned with information seeking, but rather, is simply a behaviour which occurs within the broader set of everyday practices reflects Couldry’s (2004) media as practice paradigm. These findings highlight the need for more authentic and holistic contexts for media research. It is insufficient to consider information choices in isolation, or even from a wider range of information sources, such as that incorporated in the present study. Future media research must take greater account of the broader social contexts and practices in which media-oriented behaviours occur. The findings also call into question the previously assumed centrality of trust to information selection decisions. Citizens regularly use media they do not trust to find out about politics. If people are willing to use information sources they do not trust for democratically important topics such as politics, it is important that citizens possess the media literacy skills to effectively understand and evaluate the information they are presented with. Without the application of such media literacy skills, a steady diet of ‘fast food’ media may result in uninformed or misinformed voting decisions, which have implications for the effectiveness of democratic processes. This research has emphasized the need for further holistic and authentically contextualised media use research, to better understand how citizens use information sources to find out about important topics such as politics.

Adolescent experiences of 'family meals' in Australia

Popular discourse laments the decline of the ‘family meal’, leading to family fragmentation and nutritional compromise. This article reports findings of a study investigating beliefs and practices surrounding the ‘family meal’, using data drawn from an on-line survey completed by 625 adolescents in Perth, Western Australia. The results challenge current concerns about the loss of the ‘family meal’, demonstrating that, for a majority, meals are eaten together rather than in isolation; are home-made rather than store bought or fast food; and are sites of conversation regardless of the presence of a television. Adolescents are divided, however, on the value of the ‘family meal’, with half seeing it as a positive experience of family togetherness and half regarding it negatively or as unimportant. The findings go some way to dispelling the notion that the ‘family meal’ no longer exists in Australia.

The Select Committee Report on Obesity (2004): The significant omission of parental views of their children's eating

Many studies have reported increasing levels of obesity and overweight in children. Recent policy developments have examined a range of influences on children's eating habits but have left largely unexamined the role of parents in general and mothers in particular. In this study we examined mothers’ understandings of healthy eating and of their influence on their children's eating patterns. Semi-structured interviews were conducted with nine mothers of children aged between 4 and 12 years of age. Interviewees displayed knowledge of recommended eating practices for their children but distinguished this knowledge from actual eating practices. Avoidance of negative social perceptions, pleasure in eating and opportunities for fast food were regarded as more important than eating in accordance with recommended nutritional guidelines. Moreover, the food choices made were viewed as positive alternatives to eating based on nutritional balance. These views pose a challenge for policy initiatives to address obesity and excess weight in children. Future initiatives should have increased regard for the everyday contexts within which children's eating patterns are understood and justified.

Transitions in taste in Vietnam and the diaspora

This paper argues that food and styles of eating have become the predominant markers of social change for the Vietnamese in both Vietnam and in the diaspora. In post-socialist Vietnam the transition to a market economy has allowed for a huge growth in the number of restaurants and cafes, and in the north, a return to an earlier style of cooking. The intense interest and emphasis on food as embodied pleasure has meant that it has come to stand for the transition away from a heavily state-controlled economy. The new configurations of family and friendship are being framed by newly available ways of ‘eating out’, which are both a means of social display and distinction as well as an indicator of the tensions between reform and festivity within an authoritarian nation-state struggling to define itself in a globalising world. At the same time as food in Vietnam is undergoing rapid transformation so too has the Vietnamese diaspora enerationally changed its eating patterns. Although there as been a focus in the literature on food in the diaspora that emphasises the nostalgic and recuperative elements of ‘migrant food’, I argue that food is the prime mechanism of intercultural engagement for each diasporic generation. For older Vietnamese, Vietnamese restaurants and barbecues have been the sites of interplay between cultural tradition’ and innovation, and between Australianness and Vietnameseness, and these interstitial places continue to be important for younger Vietnamese. Within this established framework of cross-cultural interaction, for Vietnamese youth, the social settings of ‘ethnic food’, eaten at home and shared with family, have been grafted onto a sociality of eating fast food. This melding together of both invention and convention, of transgression and ordinariness provides the background against which young people from migrant backgrounds are reinvigorating the social spaces of food consumption and in the process both e-enchanting and destabilising the notion of migrant food.

University students and their working pathways

This paper examines the working pathways of young full-time university students in Australia. It draws on some of the data from a three year research project funded by the Australian Research Council. The project was called ‘Changing the way that Australian enter the workforce: Part-time working careers of young full-time school and tertiary students’. The project had three industry partners: Service Skills Australia (the Industry Skills Council for the service industries), McDonalds Australia (a fast food company) and The Reject Shop (a discount chain). Much of the research took place inside companies, in schools and with national stakeholders (eg Smith & Patton, 2011; Smith & Patton, 2013), but this paper reports on the research that took place with students in universities. In the project we were keen to explore the notion of part-time working while studying as a medium-term career, especially in the context of the need for career flexibility and adaptability (Poehnell & Amundson, 2002).

Videogames: Dispelling myths and tabloid headlines that videogames are bad

Videogamers are often portrayed as adolescent overweight males eating fast food in their bedroom, and videogames often blamed in the media for violent crime, obesity, social isolation and depression. However videogaming is a mainstream activity. In Australia 65% of the population play videogames (Digital Australia 2014), and humanity as a species play about 3 billion hours of videogames a week. This paper dispels the myths and sensationalised negative tabloid headlines that videogames are bad by presenting the latest research showing that videogames can help fight depression, improve brain function and stimulate creativity; that gamers have higher levels of family closeness and better attachment to school; and that videogames help boys and young men to relax, cope and socialise. Children and adolescents deliberately choose to play videogames in the knowledge that they will feel better as a result, and videogame play allow players to express themselves in ways they may not feel comfortable doing in real life because of their appearance, gender, sexuality, and/or age. The potential benefits of videogames to the individual and to society are yet to be fully realised. However already videogames are helping many gamers to flourish in life.

How does commuting behavior change due to incentives? An empirical study of the Beijing Subway System

This study examines the impact of incentives on commuters' travel behavior based upon a questionnaire survey conducted with respect to the Beijing Subway System. Overall, we find that offering incentives to commuters, particularly fast food restaurant-related services and reduced ticket fares, has a positive influence on avoiding the morning rush hour. Furthermore, by using an interaction analysis, we discover that a flexible work schedule has an impact on commuters' behavior and the efficiency of the subway system. Finally, we recommend two possible policies to maximize the utility of the subway system and to reduce congestion at the peak of morning service: (1) a set of incentives that includes free wireless internet service with a coupon for breakfast and a discount on ticket fares before the morning peak, and; (2) the introduction of a flexible work schedule.

Applications of Treatment Effects Models and Semiparametric Estimation

This thesis is composed of an introductory chapter and four applications each of them constituting an own chapter. The common element underlying each of the chapters is the econometric methodology. The applications rely mostly on the leading econometric techniques related to estimation of causal effects. The first chapter introduces the econometric techniques that are employed in the remaining chapters. Chapter 2 studies the effects of shocking news on student performance. It exploits the fact that the school shooting in Kauhajoki in 2008 coincided with the matriculation examination period of that fall. It shows that the performance of men declined due to the news of the school shooting. For women the similar pattern remains unobserved. Chapter 3 studies the effects of minimum wage on employment by employing the original Card and Krueger (1994; CK) and Neumark and Wascher (2000; NW) data together with the changes-in-changes (CIC) estimator. As the main result it shows that the employment effect of an increase in the minimum wage is positive for small fast-food restaurants and negative for big fast-food restaurants. Therefore, it shows that the controversial positive employment effect reported by CK is overturned for big fast-food restaurants and that the NW data are shown, in contrast to their original results, to provide support for the positive employment effect. Chapter 4 employs the state-specific U.S. data (collected by Cohen and Einav [2003; CE]) on traffic fatalities to re-evaluate the effects of seat belt laws on the traffic fatalities by using the CIC estimator. It confirms the CE results that on the average an implementation of a mandatory seat belt law results in an increase in the seat belt usage rate and a decrease in the total fatality rate. In contrast to CE, it also finds evidence on compensating-behavior theory, which is observed especially in the states by the border of the U.S. Chapter 5 studies the life cycle consumption in Finland, with the special interest laid on the baby boomers and the older households. It shows that the baby boomers smooth their consumption over the life cycle more than other generations. It also shows that the old households smoothed their life cycle consumption more as a result of the recession in the 1990s, compared to young households.

Análisis sobre imagen y posicionamiento de restaurantes de comida rápida (Alemania)

El trabajo comienza con una introducción al mercado de restaurantes de comida rápida, en la que se analizará la situación actual y se definirán diversos conceptos, como imagen y posicionamiento, que serán importantes para comprender mejor este estudio. A continuación, se plantearán los objetivos y subobjetivos del trabajo y se describirá la metodología utilizada. En este trabajo se analizarán las percepciones sobre siete restaurantes de comida rápida: McDonald’s, Burger King, Domino’s Pizza, Döner Kebab, Subway, Nordsee y KFC. Después de explicar el proceso de obtención de los datos y detallar los problemas surgidos al realizar el trabajo de campo, se analizarán los datos recogidos. En primer lugar, a través del análisis de la varianza hemos podido comprobar que existen diferencias significativas entre los restaurantes de comida rápida en cuanto a cómo son percibidos. A continuación, mediante el análisis cluster hemos agrupado en distintos grupos a los restaurantes similares. Asimismo, se ha realizado un análisis de componentes principales para describir el posicionamiento de los restaurantes estudiados. Por último, una vez tratados los datos obtenidos en los cuestionarios, se procederá a analizar la apertura de un restaurante de comida rápida que ofrezca comida mediterránea, planteando su estrategia de marketing. En este sentido, se define el posicionamiento de la nueva marca y las características del público objetivo. También se detallan diversas acciones del marketing mix (políticas de producto, precio, distribución y comunicación).

Consumo alimentar e associação com ganho de peso em adolescente: Estudo Longitudinal de Avaliação Nutricional de Adolescentes (ELANA).

Essa tese teve como objetivo avaliar a associação do consumo de padrões alimentares e produtos alimentícios ultraprocessados (UP) sobre indicadores antropométricos e sua variação entre adolescentes. Para tal, foram analisados os dados de 1.031 estudantes de quatro escolas privadas e duas escolas públicas da região metropolitana do Rio de Janeiro que foram acompanhados por três anos consecutivos (2010 a 2012) no Estudo Longitudinal de Avaliação Nutricional de adolescentes (ELANA). Os resultados estão apresentados em três manuscritos que compõem a tese. O primeiro manuscrito identificou três padrões alimentares: Ocidental, composto por massas, embutidos e bacon, carnes, doces, bebidas açucaradas, salgados e fast food, biscoito, pães e cereais, leite e derivados e ovos, o Saudável, caracterizado por peixes, hortaliças, verduras, raízes e feculentos, frutas e sucos e o Arroz/Feijão, composto pelo consumo de arroz, feijão e café. Na análise dos dados na linha de base o padrão Ocidental associou-se a um menor índice de massa corporal (IMC) e não foi observada associação estatisticamente significativa em relação ao percentual de gordura corpórea (%GC) e o padrão em questão. Adicionalmente, foi verificada uma associação negativa entre o padrão Arroz/Feijão e ambos os indicadores antropométricos sugerindo que esse padrão de consumo tradicional possa ser protetor para a obesidade. No segundo manuscrito avaliou-se a relação entre o consumo de UP e indicadores de qualidade da dieta. O consumo de UP foi avaliado em gramas por dia e em gramas/total de calorias. Observou-se um aumento das variáveis marcadoras de alimentação não saudável e saudável com o aumento do consumo de UP. No entanto, quando relacionados ao aumento de consumo de UP/energia observou-se um aumento de marcadores de alimentação não saudável e, com exceção da vitamina C, uma redução de marcadores de alimentação saudável. Assim, a densidade do consumo de UP mostrou-se um bom indicador de qualidade da dieta entre adolescentes. No terceiro manuscrito avaliou-se a associação entre o consumo de UP e a evolução temporal do IMC e %GC. A análise longitudinal por modelos lineares mistos, que levam em conta todas as observações ao longo do tempo, indicou que nas análises não ajustados havia uma associação negativa entre consumo de UP e o IMC e %GC, porém nas análises de UP/energia e nas análises ajustadas por atividade física e uma variável de controle para a qualidade do relato não mais foram observadas associações com o consumo de UP e as medidas antropométricas de adiposidade. Pode-se concluir que não evidenciamos associação do consumo de UP com medidas antropométricas de obesidade uma vez que o consumo elevado de UP associado ao crescimento do %GC nas análises transversais, não se manteve nas análises longitudinais. A discrepância entre os achados dos estudos seccionais e os longitudinais pode decorrer de confundimento residual nos estudos seccionais. Conclui-se, que para redução do ganho excessivo de peso, orientações relativas exclusivamente a um padrão de alimentação saudável que incorpora a ideia de UP, devem ser acompanhadas de redução da quantidade de alimentos consumidos.

Collaborative artistic laboratories. Transfrontier spaces of cultural production

The appearance of the open code paradigm and the demands of social movements have permeated the ways in which today’s cultural institutions are organized. This article analyzes the birth of a new critical and cooperative spatiality and how it is transforming current modes of cultural research and production. It centers on the potential for establishing the new means of cooperation that are being tested in what are defined as collaborative artistic laboratories. These are hybrid spaces of research and creation based on networked and cooperative structures producing a new societal-technical body that forces us to reconsider the traditional organic conditions of the productive scenarios of knowledge and artistic practice.

Caught in a 'spiral': barriers to healthy eating and dietary health promotion needs from the perspective of unemployed young people and their service providers

The number of young people in Europe who are not in education, employment or training (NEET) is increasing. Given that young people from disadvantaged backgrounds tend to have diets of poor nutritional quality, this exploratory study sought to understand barriers and facilitators to healthy eating and dietary health promotion needs of unemployed young people aged 16-20 years. Three focus group discussions were held with young people (n=14). Six individual interviews and one paired interview with service providers (n=7). Data were recorded, transcribed verbatim and thematically content analysed. Themes were then fitted to social cognitive theory (SCT). Despite understanding of the principles of healthy eating, a ‘spiral’ of interrelated social, economic and associated psychological problems was perceived to render food and health of little value and low priority for the young people. The story related by the young people and corroborated by the service providers was of a lack of personal and vicarious experience with food. External, environmental factors such as the proliferation and proximity of fast food outlets and the high perceived cost of ‘healthy’ compared to ‘junk’ food rendered the young people low in self-efficacy and perceived control to make healthier food choices. Agency was instead expressed through consumption of junk food and substance abuse. Both the young people and service providers agreed that for dietary health promotion efforts to succeed, social problems needed addressed and agency encouraged through (individual and collective) active engagement of the young people themselves.
