Tracking of maternal self-efficacy for limiting young children's television viewing and associations with children's television viewing time: a longitudinal analysis over 15-months

BACKGROUND: Mothers' self-efficacy for limiting their children's television viewing is an important correlate of this behaviour in young children. However, no studies have examined how maternal self-efficacy changes over time, which is potentially important during periods of rapid child development. This study examined tracking of maternal self-efficacy for limiting young children's television viewing over 15-months and associations with children's television viewing time. METHODS: In 2008 and 2010, mothers (n = 404) from the Melbourne InFANT Program self-reported their self-efficacy for limiting their child's television viewing at 4- and 19-months of age. Tertiles of self-efficacy were created at each time and categorised into: persistently high, persistently low, increasing or decreasing self-efficacy. Weighted kappa and multinomial logistic regression examined tracking and demographic and behavioural predictors of change in self-efficacy. A linear regression model examined associations between tracking categories and children's television viewing time. RESULTS: Tracking of maternal self-efficacy for limiting children's television viewing was low (kappa = 0.23, p < 0.001). Mothers who had persistently high or increasing self-efficacy had children with lower television viewing time at 19-months (β = -35.5; 95 % CI = -54.4,-16.6 and β = 37.0; 95 % CI = -54.4,-19.7, respectively). Mothers of children with difficult temperaments were less likely to have persistently high self-efficacy. Mothers who met adult physical activity guidelines had 2.5 greater odds of increasing self-efficacy. CONCLUSIONS: Interventions to increase and maintain maternal self-efficacy for limiting children's television viewing time may result in lower rates of this behaviour amongst toddlers. Maternal and child characteristics may need to be considered when tailoring interventions.

BMI and healthcare cost impact of eliminating tax subsidy for advertising unhealthy food to youth

INTRODUCTION: Food and beverage TV advertising contributes to childhood obesity. The current tax treatment of advertising as an ordinary business expense in the U.S. subsidizes marketing of nutritionally poor foods and beverages to children. This study models the effect of a national intervention that eliminates the tax subsidy of advertising nutritionally poor foods and beverages on TV to children aged 2-19 years. METHODS: We adapted and modified the Assessing Cost Effectiveness framework and methods to create the Childhood Obesity Intervention Cost Effectiveness Study model to simulate the impact of the intervention over the 2015-2025 period for the U.S. population, including short-term effects on BMI and 10-year healthcare expenditures. We simulated uncertainty intervals (UIs) using probabilistic sensitivity analysis and discounted outcomes at 3% annually. Data were analyzed in 2014. RESULTS: We estimated the intervention would reduce an aggregate 2.13 million (95% UI=0.83 million, 3.52 million) BMI units in the population and would cost $1.16 per BMI unit reduced (95% UI=$0.51, $2.63). From 2015 to 2025, the intervention would result in $352 million (95% UI=$138 million, $581 million) in healthcare cost savings and gain 4,538 (95% UI=1,752, 7,489) quality-adjusted life-years. CONCLUSIONS: Eliminating the tax subsidy of TV advertising costs for nutritionally poor foods and beverages advertised to children and adolescents would likely be a cost-saving strategy to reduce childhood obesity and related healthcare expenditures.

Moving images effective teaching with film and television in management

This book will inspire academics, teachers and trainers to use film and television in their classrooms and to shows them how it might be done. It brings together respected international scholars who recount their experiences of how they have used moving images in their classrooms (defined widely to include distance-learning) with their explanations of why they chose this method of teaching and how they put their intentions into action. The book also illustrates how particular subjects might be taught using film and television as an inspiration to demonstrate the range of opportunities that these media offer. Finally, this book considers some of the practical issues in using film and television in the classroom such as copyright, technology, and the representation of reality and drama in films. This is a 'practical, how to' book that answers the questions of those people who have considered using film and television in their classroom but until now have shied away from doing so. The opportunity to see how others have used film effectively breaks down psychological barriers and makes it seem both realistic and worthwhile.

Advertising the 2015 Cricket World Cup: representing multicultural female sports fans

Intersectional accounts of how women sports fans from diverse cultural backgrounds are represented remain largely unconsidered in fandom literature. This article examines an Australian advertisement for the 2015 Cricket World Cup, which features as its main protagonists female cricket fans supporting a variety of countries. It makes use of a transnational feminist cultural studies paradigm to frame a discussion of how commercial sports media narratives situate these fans as ‘‘ordinary.’’ In considering how the multicultural female sports fan is configured as ordinary in the Australian sporting context, I demonstrate the ways In which narratives of gender and nation are mobilized to situate multicultural women as marginal to both the Australian nation and cricket, despite the prominence given to ethnically diverse women in the advertisement. This manoeuvre, I argue, responds to the cultural and economic transformations of cricket globally, simultaneously denying and universalizing difference as a mechanism to assuage the anxieties generated by the decentering of Western power in international cricket.

Eat, drink and gamble: marketing messages about 'risky' products in an Australian major sporting series

BACKGROUND: To investigate the alcohol, gambling, and unhealthy food marketing strategies during a nationally televised, free to air, sporting series in Australia. METHODS/APPROACH: Using the Australian National Rugby League 2012 State of Origin three-game series, we conducted a mixed methods content analysis of the frequency, duration, placement and content of advertising strategies, comparing these strategies both within and across the three games. RESULTS: There were a total of 4445 episodes (mean = 1481.67, SD = 336.58), and 233.23 minutes (mean = 77.74, SD = 7.31) of marketing for alcoholic beverages, gambling products and unhealthy foods and non-alcoholic beverages during the 360 minutes of televised coverage of the three State of Origin 2012 games. This included an average per game of 1354 episodes (SD = 368.79) and 66.29 minutes (SD = 7.62) of alcohol marketing; 110.67 episodes (SD = 43.89), and 8.72 minutes (SD = 1.29) of gambling marketing; and 17 episodes (SD = 7.55), and 2.74 minutes (SD = 0.78) of unhealthy food and beverage marketing. Content analysis revealed that there was a considerable embedding of product marketing within the match play, including within match commentary, sporting equipment, and special replays. CONCLUSIONS: Sport is increasingly used as a vehicle for the promotion of range of 'risky consumption' products. This study raises important ethical and health policy questions about the extent and impact of saturation and incidental marketing strategies on health and wellbeing, the transparency of embedded marketing strategies, and how these strategies may influence product consumption.

Physical activity, television viewing time and 12 year changes in waist circumference

PURPOSE: Both moderate-to-vigorous physical activity (MVPA) and sedentary behavior can be associated with adult adiposity. Much of the relevant evidence is from cross-sectional studies or from prospective studies with relevant exposure measures at a single time point prior to weight gain or incident obesity. This study examined whether changes in MVPA and television (TV) viewing time are associated with subsequent changes in waist circumference, using data from three separate observation points in a large population-based prospective study of Australian adults. METHODS: Data were obtained from the Australian Diabetes, Obesity and Lifestyle study collected in 1999-2000 (baseline), 2004-05 (Wave 2), and 2011-12 (Wave 3). The study sample consisted of adults aged 25 to 74 years at baseline who also attended site measurement at three time points (n=3261). Multilevel linear regression analysis examined associations of initial five-year changes in MVPA and TV viewing time (from baseline to Wave 2) with 12-year change in waist circumference (from baseline to Wave 3), adjusting for well-known confounders. RESULTS: As categorical predictors, increases in MVPA significantly attenuated increases in waist circumference (p for trend< 0.001). TV viewing time change was not significantly associated with changes in waist circumference (p for trend =0.06). Combined categories of MVPA and TV viewing time changes were predictive of waist circumference increases; compared to those who increased MVPA and reduced TV viewing time, those who reduced MVPA and increased TV viewing time had a 2cm greater increase in waist circumference (p=0.001). CONCLUSION: Decreasing MVPA emerged as a significant predictor of increases in waist circumference. Increasing TV viewing time was also influential, but its impact was much weaker than MVPA.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Extraordinary television time travel and the wonderful end to the working day

In this article I will present two arguments. First, the argument that the time travel television series historically provided viewers with a spectacular temporal and spatial alternative to the routine of everyday life, the regulation of television scheduling, and the small-world confines of domestic subjectivity. Taking the decades of the 1970s and 1980s, predominantly in a UK viewing environment, I will suggest that the special effect rendering of the time travel sequence expanded the viewer’s material universe, and affectively wrenched the television set free from the strictures of scheduling and realist programming. Further, the time travel series readily and regularly took the domestic space, the ordinary day and the everyman/ person into awesome environments and situations that suggested alternative lifestyles and behaviours, with a different existential tempo and rhythm. At a narrative, thematic, meta- textual, and aesthetically spectacular level, television time travel saw to the wonderful end of the working day. Case studies include Sapphire and Steal, Dr Who, and Quantum Leap. Second, the article will argue that rather than the contemporary time travel television series being an extraordinary alternative to ordinary life, they instead articulate convergence culture, deregulation, multiple channel viewing, and time-shift culture where there is no such thing as an ordinary working day or domestic viewing context.

Weaving a web: subaltern consumers, rising consumer culture, and television

Cultivation analysis suggests that television influences local cultures through its complex repertoire of images and narratives, which constitute a representation. Through a discursive analysis of television content in India we contend that rising material aspirations and consumer culture are significantly influenced by this medium. Dialectics of turmoil and tranquility mark this development for the working class population. On the one hand, there is domestication of unrest among subaltern groups, as they withdraw from collective political struggles to narrower and more tranquil forms of emulation and economism. On the other hand, these attempts at emulation have resulted in the poorer sections of society devoting their limited resources to aping a lifestyle well beyond their reach and further compromising their quality of life. The other pole of the dialectic is the increase in turmoil that results from tearing the traditional social fabric and support systems. This turmoil progressively manifests itself in increasing materialism and greater monetization of relationships for these subaltern groups.

Associations between physical activity, television viewing and postnatal depressive symptoms amongst healthy primiparous mothers

Background: Postnatal depression is a serious illness in new mothers. In the general population, physical activity (PA) has been found to reduce the risk of depression, whilst sedentary behaviour (SB; in particular television viewing) has been linked to higher levels of depressive symptoms, yet little is known regarding associations between PA, SB and postnatal depression. This study aimed to investigate associations between PA, television viewing and postnatal depressive symptoms in healthy primiparous mothers.. Methods: Cross-sectional survey data were provided by 406 first-time mothers (approximately 3-months postpartum) enrolled in the Melbourne InFANT Extend trial (2012/2013). Women self-reported PA (time spent walking for leisure and transport, and other moderate and vigorous PA), television viewing, and depressive symptoms (CES-D 10). Random intercept linear models examined associations between PA, television viewing and depressive symptoms. Results: In crude models total PA was inversely associated with risk of postnatal depressive symptoms (B = -0.122; 95% CI = -0.24, -0.01). In models adjusted for key sociodemographic and behavioural covariates the association did not remain statistically significant. No other associations between PA, television viewing and postnatal depressive symptoms were evident.. Conclusions: Postnatal depressive symptoms may not be related to PA and television viewing in the same way that these behaviours predict depressive symptoms in the general population. Further investigation of the specific domains of PA, as well as different types/contexts of SB and their respective associations with postnatal depressive symptoms is warranted in order to better inform development of targeted interventions aimed at enhancing postnatal mental health..

Can creativity be managed? An advertising agency case study

Despite the large amount of creativity research which exists the nature of the phenomenon and how it comes about remains contested. Mainstream research assumes creativity is the result of a creative individual's efforts and is an inherent feature of an artefact. An alternate view postulates that creativity is contextual, occurs due to social processes, is subjective and contingent. Lack of agreement has ramifications for practitioners who are faced with a dilemma as to how to approach creativity within organisations. This research looks at creativity within an advertising agency through an alternative lens to see if this is useful and to assess whether it is able to contribute to the debate by providing new insight into the phenomenon. Findings show a number of social processes involved in the construction of creativity in this environment. This paper concludes by arguing that having an in-depth understanding of how creativity happens can provide practitioners with a basis for reflection and the foundation for development of an action plan around the management of creativity.

It's not just the television: survey analysis of sedentary behaviour in New Zealand young people

BACKGROUND: Sedentary behaviour has been linked with adverse health outcomes in young people; however, the nature and context of being sedentary is poorly understood. Accurate quantification and description of sedentary behaviour using population-level data is required. The aim of this research was to describe sedentary behaviour among New Zealand (NZ) youth and examine whether sedentary behaviour differs by Body Mass Index (BMI) status in this population.

METHODS: A national representative cross-sectional survey of young people aged 5-24 years (n = 2,503) was conducted in 2008-2009. Data from this survey, which included subjectively (recall diary; n = 1,309) and objectively (accelerometry; n = 960) measured sedentary behaviour for participants aged 10-18 years were analysed using survey weighted methods.

RESULTS: Participants self-reported spending on average 521 minutes per day (standard error [SE] 5.29) in total sedentary behaviour, 181 minutes per day (SE 3.91) in screen-based sedentary activities (e.g., television and video games), and 340 minutes per day (SE 5.22) in other non-screen sedentary behaviours (e.g., school, passive transport and self-care). Accelerometer-measured total sedentary behaviour was on average 420 minutes per day (SE 4.26), or 53% (SE 0.42%) of monitored time. There were no statistically significant differences in time spent in sedentary behaviour among overweight, obese and healthy/underweight young people.

CONCLUSIONS: Both subjective and objective methods indicate that NZ youth spend much of their waking time being sedentary. No relationships were found between sedentary behaviour and BMI status. These findings extend previous research by describing engagement in specific sedentary activities, as well as quantifying the behaviour using an objective method. Differences in what aspects of sedentary behaviour the two methods are capturing are discussed. This research highlights the potential for future interventions to target specific sedentary behaviours or demographic groups.
