Alcohol advertising: the last chance saloon

Research has established that alcohol advertising,1-3 like that for tobacco4 and fast food,5-7 influences behaviour. It encourages young people to drink alcohol sooner and in greater quantities. From a public health perspective, advertising of alcohol should clearly be limited. The United Kingdom has opted for a system of self regulatory controls that focuses primarily on the content of advertisements, with some limitations on the channels that can be used. This is overseen by the Advertising Standards Authority, through the Committee of Advertising Practice, which represents the interests of advertisers, agencies, and media owners.As part of its alcohol inquiry, the House of Commons health select committee wanted to explore the success of self regulation. It obtained a large number of internal marketing documents from alcohol producers and their communications agencies in order to examine the thinking and strategic planning that underpin alcohol advertising and hence show not just what advertisers are saying, but why they are saying it. Here we present the key insights to emerge

Multilevel interpolation of divergence-free vector fields

We introduce a multilevel technique for interpolating scattered data of divergence-free vector fields with the help of matrix-valued compactly supported kernels. The support radius at a given level is linked to the mesh norm of the data set at that level. There are at least three advantages of this method: no grid structure is necessary for the implementation, the multilevel approach is computationally cheaper than solving a large one-shot system and the interpolant is guaranteed to be analytically divergence-free. Furthermore, though we will not pursue this here, our multiscale approach is able to represent multiple scales in the data if present. We will prove convergence of the scheme, stability estimates and give a numerical example

A systematic review of digital interventions for improving the diet and physical activity behaviors of adolescents

Many adolescents have poor diet and physical activity behaviors, which can lead to the development of noncommunicable diseases in later life. Digital platforms offer inexpensive means of delivering health interventions, but little is known about their effectiveness. This systematic review was conducted to synthesize evidence on the effectiveness of digital interventions to improve diet quality and increase physical activity in adolescents, to effective intervention components and to assess the cost-effectiveness of these interventions. Following a systematic search, abstracts were assessed against inclusion criteria, and data extraction and quality assessment were performed for included studies. Data were analyzed to identify key features that are associated with significant improvement in behavior. A total of 27 studies met inclusion criteria. Most (n = 15) were Web site interventions. Other delivery methods were text messages, games, multicomponent interventions, emails, and social media. Significant behavior change was often seen when interventions included education, goal setting, self-monitoring, and parental involvement. None of the publications reported cost-effectiveness. Due to heterogeneity of studies, meta-analysis was not feasible.It is possible to effect significant health behavior change in adolescents through digital interventions that incorporate education, goal setting, self-monitoring, and parental involvement. Most of the evidence relates to Web sites and further research into alternate media is needed, and longer term outcomes should be evaluated. There is a paucity of data on the cost-effectiveness of digital health interventions, and future trials should report these data

"They'll drink bucket loads of the stuff": An analysis of internal alcohol industry documents

First paragraph: As part of its 2009 investigation into the conduct of the UK alcohol industry, the House of Commons Health Select Committee obtained access to internal marketing documents from both producers and their advertising agencies. These reveal major shortcomings in the current self regulatory codes covering alcohol advertising. Specifically, the codes do not, as they are supposed to, protect young people from alcohol advertising; prevent the promotion of drunkenness and excess; or the linking of alcohol with social and sexual success. Nor do they even attempt to address sponsorship, and the documents show this is being systematically used to undermine rules prohibiting the linking of alcohol with youth culture and sporting prowess. Finally, the codes are extremely weak in their treatment of new media which are rapidly become the biggest channel for alcohol promotion. The result is a regulatory system that is impossible to police and vulnerable to exploitation

Cardiovascular risk and systemic inflammation in male professional rugby: a cross-sectional study

Objective: To investigate cardiovascular risk factors’ prevalence and association with systemic inflammation in professional male rugby players (RP). Methods: A cross-sectional investigation of 46 professional male RP (26.1±4.1 years) cardiovascular risk factors were compared by position. Inflammatory markers were compared with healthy controls (n=13) and patients with rheumatoid arthritis (RA) (n=10). Results: Twenty-six per cent of RP had no risk factors, 49% had 1–2 cardiovascular risk factors and 25% had 3–4 risk factors. Forwards had greater body fat (p<0.001), visceral fat (p<0.001), glucose (p=0.025), and C reactive protein (CRP) (p=0.023) compared with backs. RP demonstrated more favourable lipid and glucose profiles than reference values for the general population. Most RP (n=28, 61%) had elevated blood pressure (≥140/90 mm Hg). RP had higher vascular adhesion molecule-1 (VCAM-1) (p=0.004) and intracellular adhesion molecule-1 (ICAM-1) (p=0.002) than healthy controls. RP had lower CRP than patients with RA (p=0.009), while one-third (n=15) displayed equivalent ICAM-1 and VCAM-1 levels. Multivariate clustering and principal component analysis biplots revealed higher triglycerides, inflammatory markers, and worse body composition were associated with forwards. Conclusions: Despite athletic status, most of this rugby cohort had at least one cardiovascular risk factor. Concomitantly, these RP demonstrated increased levels of inflammation, with one-third, primarily forwards, displaying equivalent levels to patients with inflammatory disease. Further studies are needed to unravel the prognostic implications of increased inflammation in RP because unchecked, chronic inflammation may lead to increased cardiovascular disease risk

Physical and technical demands and preparatory strategies in female field collision sports: a scoping review

Women’s participation in field collision sports is growing world- wide. Scoping reviews provide an overview of scientific litera- ture in a developing area to support practitioners, policy, and research priorities. Our aim is to explore published research and synthesise information on the physical and technical de- mands and preparation strategies of female field collision sports. We searched four databases and identified relevant published studies. Data were extracted to form (1) a numerical analysis and (2) thematic summary. Of 2318 records identified, 43 studies met the inclusion criteria. Physical demands were the most highly investigated (n = 24), followed by technical demands (n = 18), tactical considerations (n = 8) and preparatory strategies (n = 1). The key themes embody a holistic model contributing to both performance and injury prevention outcomes in the context of female field collision sports. Find- ings suggest a gender data gap across all themes and a low evidence base to inform those preparing female athletes for match demands. Given the physical and technical differences in match-demands the review findings do not support the generalisation of male-derived training data to female athletes. To support key stakeholders working within female field collision sports there is a need to increase the visibility of female athletes in the literature.<br/
