RESUMO
BACKGROUND: Understand factors that influence food choice and explore public perceptions of the need for government policies to improve diets in the UK, particularly food pricing interventions. METHODS: A qualitative study design was used with semi-structured interviews. The study was carried out in Greater Manchester, England. In all, 15 participants from a diverse range of backgrounds were recruited. RESULTS: Food price, lack of time, availability, and food knowledge and culture were key factors that led some study participants towards unhealthy food choices. The UK's individual, willpower-focused approach to tackling obesity was deemed ineffective and many participants supported further government intervention. Product reformulation was supported as a less intrusive and less regressive way of improving diets than taxation. There was also support for increasing cooking classes within schools. CONCLUSIONS: Whilst the government ambition to half childhood obesity by 2030 is welcome, population level interventions that enable healthier food choices are needed to achieve this goal. Rising global food prices may make reformulation a more practical policy option than further pricing interventions. Mandatory reformulation of convenience meal and snack products and strengthening education in schools may represent a publicly acceptable and effective package of interventions within a comprehensive strategy to tackle obesity.

BACKGROUND: Local authorities in England commission the NHS Health Check programme to invite everyone aged 40-74 years without pre-existing conditions for risk assessment and eventual intervention, if needed. However, the programme's effectiveness, cost-effectiveness and equity impact remain uncertain. AIM: To develop a validated open-access flexible web-based model that enables local commissioners to quantify the cost-effectiveness and potential for equitable population health gain of the NHS Health Check programme. OBJECTIVES: The objectives were as follows: (1) co-produce with stakeholders the desirable features of the user-friendly model; (2) update the evidence base to support model and scenario development; (3) further develop our computational model to allow for developments and changes to the NHS Health Check programme and the diseases it addresses; (4) assess the effectiveness, cost-effectiveness and equity of alternative strategies for implementation to illustrate the use of the tool; and (5) propose a sustainability and implementation plan to deploy our user-friendly computational model at the local level. DESIGN: Co-production workshops surveying the best-performing local authorities and a systematic literature review of strategies to increase uptake of screening programmes informed model use and development. We then co-produced the workHORSE (working Health Outcomes Research Simulation Environment) model to estimate the health, economic and equity impact of different NHS Health Check programme implementations, using illustrative-use cases. SETTING: Local authorities in England. PARTICIPANTS: Stakeholders from local authorities, Public Health England, the NHS, the British Heart Foundation, academia and other organisations participated in the workshops. For the local authorities survey, we invited 16 of the best-performing local authorities in England. INTERVENTIONS: The user interface allows users to vary key parameters that represent programme activities (i.e. invitation, uptake, prescriptions and referrals). Scenarios can be compared with each other. MAIN OUTCOME MEASURES: Disease cases and case-years prevented or postponed, incremental cost-effectiveness ratios, net monetary benefit and change in slope index of inequality. RESULTS: The survey of best-performing local authorities revealed a diversity of effective approaches to maximise the coverage and uptake of NHS Health Check programme, with no distinct 'best buy'. The umbrella literature review identified a range of effective single interventions. However, these generally need to be combined to maximally improve uptake and health gains. A validated dynamic, stochastic microsimulation model, built on robust epidemiology, enabled service options analysis. Analyses of three contrasting illustrative cases estimated the health, economic and equity impact of optimising the Health Checks, and the added value of obtaining detailed local data. Optimising the programme in Liverpool can become cost-effective and equitable, but simply changing the invitation method will require other programme changes to improve its performance. Detailed data inputs can benefit local analysis. LIMITATIONS: Although the approach is extremely flexible, it is complex and requires substantial amounts of data, alongside expertise to both maintain and run. CONCLUSIONS: Our project showed that the workHORSE model could be used to estimate the health, economic and equity impact comprehensively at local authority level. It has the potential for further development as a commissioning tool and to stimulate broader discussions on the role of these tools in real-world decision-making. FUTURE WORK: Future work should focus on improving user interactions with the model, modelling simulation standards, and adapting workHORSE for evaluation, design and implementation support. STUDY REGISTRATION: This study is registered as PROSPERO CRD42019132087. FUNDING: This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 25, No. 35. See the NIHR Journals Library website for further project information.
The NHS Health Check programme is available for adults aged 4074 years in England to find the early risk of heart disease, cancers, lung disease and dementia, and lower that risk. However, some studies have suggested that the current scheme could perhaps be improved. We systematically looked at previous studies to understand what makes a screening programme successful. We also contacted local authorities with the best NHS Health Check programmes to find out how they were being delivered so well. The most successful local authorities highlighted a wide variety of methods for achieving success. All had concrete plans in place for delivery, including different approaches for encouraging more adults to participate. We further developed our existing computer model into a web-based tool [workHORSE (working Health Outcomes Research Simulation Environment)]. This tool can help those responsible for commissioning NHS Health Checks to further improve the delivery of their local programme. We held four workshops with relevant professionals to develop the workHORSE model. These workshops resulted in a useful 'real-world' tool for local commissioners: a tool that can calculate the current and potential future benefits of different programmes. We used the model to show how commissioners can explore and compare a variety of different programmes. We found that combining several improvements can be useful. However, this provides modest benefits in improving health and value for money. At the same time, the impact on reducing inequalities is less clear and depends on the interventions used. Our results suggest that: a variety of successful approaches can be used to help increase the uptake of screening programmes such as NHS Health Checksjointly developing a computer model with end-users leads to a more user-friendly and relevant model to improve the programmethe stage is now set for further work to identify the best approach in each local area.

BACKGROUND: Non-communicable diseases (NCDs) account for some 90% of premature UK deaths, most being preventable. However, the systems driving NCDs are complex. This complexity can make NCD prevention strategies difficult to develop and implement. We therefore aimed to explore with key stakeholders the upstream policies needed to prevent NCDs and related inequalities. METHODS: We developed a theory-based co-production process and used a mixed methods approach to engage with policy- and decision-makers from across the United Kingdom in a series of 4 workshops, to better understand and respond to the complex systems in which they act. The first and fourth workshops (London) aimed to better understand the public health policy agenda and effective methods for co-production, communication and dissemination. In workshops 2 and 3 (Liverpool and Glasgow), we used nominal group techniques to identify policy issues and equitable prevention strategies, we prioritised emerging policy options for NCD prevention, using the MoSCoW approach. RESULTS: We engaged with 43 diverse stakeholders. They identified 'healthy environment' as an important emerging area. Reducing NCDs and inequalities was identified as important, underpinned by a frustration relating to the evidence/ policy gap. Evidence for NCD risk factor epidemiology was perceived as strong, the evidence underpinning the best NCD prevention policy interventions was considered patchier and more contested around the social, commercial and technological determinants of health. A comprehensive communications strategy was considered essential. The contribution of 'elite actors' (ministers, public sector leaders) was seen as key to the success of NCD prevention policies. CONCLUSION: NCDs are generated by complex adaptive systems. Early engagement of diverse stakeholders in a theory-based co-production process can provide valuable context and relevance. Subsequent partnership-working will then be essential to develop, disseminate and implement the most effective NCD prevention strategies.

BACKGROUND: Stakeholder engagement is being increasingly recognised as an important way to achieving impact in public health. The WorkHORSE (Working Health Outcomes Research Simulation Environment) project was designed to continuously engage with stakeholders to inform the development of an open access modelling tool to enable commissioners to quantify the potential cost-effectiveness and equity of the NHS Health Check Programme. An objective of the project was to evaluate the involvement of stakeholders in co-producing the WorkHORSE computer modelling tool and examine how they perceived their involvement in the model building process and ultimately contributed to the strengthening and relevance of the modelling tool. METHODS: We identified stakeholders using our extensive networks and snowballing techniques. Iterative development of the decision support modelling tool was informed through engaging with stakeholders during four workshops. We used detailed scripts facilitating open discussion and opportunities for stakeholders to provide additional feedback subsequently. At the end of each workshop, stakeholders and the research team completed questionnaires to explore their views and experiences throughout the process. RESULTS: 30 stakeholders participated, of which 15 attended two or more workshops. They spanned local (NHS commissioners, GPs, local authorities and academics), third sector and national organisations including Public Health England. Stakeholders felt valued, and commended the involvement of practitioners in the iterative process. Major reasons for attending included: being able to influence development, and having insight and understanding of what the tool could include, and how it would work in practice. Researchers saw the process as an opportunity for developing a common language and trust in the end product, and ensuring the support tool was transparent. The workshops acted as a reality check ensuring model scenarios and outputs were relevant and fit for purpose. CONCLUSIONS: Computational modellers rarely consult with end users when developing tools to inform decision-making. The added value of co-production (continuing collaboration and iteration with stakeholders) enabled modellers to produce a "real-world" operational tool. Likewise, stakeholders had increased confidence in the decision support tool's development and applicability in practice.

BACKGROUND: The NHS Health Check Programme is a risk-reduction programme offered to all adults in England aged 40-74 years. Previous studies mainly focused on patient perspectives and programme delivery; however, delivery varies, and costs are substantial. We were therefore working with key stakeholders to develop and co-produce an NHS Health Check Programme modelling tool (workHORSE) for commissioners to quantify local effectiveness, cost-effectiveness, and equity. Here we report on Workshop 1, which specifically aimed to facilitate engagement with stakeholders; develop a shared understanding of current Health Check implementation; identify what is working well, less well, and future hopes; and explore features to include in the tool. METHODS: This qualitative study identified key stakeholders across the UK via networking and snowball techniques. The stakeholders spanned local organisations (NHS commissioners, GPs, and academics), third sector and national organisations (Public Health England and The National Institute for Health and Care Excellence). We used the validated Hovmand "group model building" approach to engage stakeholders in a series of pre-piloted, structured, small group exercises. We then used Framework Analysis to analyse responses. RESULTS: Fifteen stakeholders participated in workshop 1. Stakeholders identified continued financial and political support for the NHS Health Check Programme. However, many stakeholders highlighted issues concerning lack of data on processes and outcomes, variability in quality of delivery, and suboptimal public engagement. Stakeholders' hopes included maximising coverage, uptake, and referrals, and producing additional evidence on population health, equity, and economic impacts. Key model suggestions focused on developing good-practice template scenarios, analysis of broader prevention activities at local level, accessible local data, broader economic perspectives, and fit-for-purpose outputs. CONCLUSIONS: A shared understanding of current implementations of the NHS Health Check Programme was developed. Stakeholders demonstrated their commitment to the NHS Health Check Programme whilst highlighting the perceived requirements for enhancing the service and discussed how the modelling tool could be instrumental in this process. These suggestions for improvement informed subsequent workshops and model development.

OBJECTIVE: In politically contested health debates, stakeholders on both sides present arguments and evidence to influence public opinion and the political agenda. The present study aimed to examine whether stakeholders in the Soft Drinks Industry Levy (SDIL) debate sought to establish or undermine the acceptability of this policy through the news media and how this compared with similar policy debates in relation to tobacco and alcohol industries. DESIGN: Quantitative and qualitative content analysis of newspaper articles discussing sugar-sweetened beverage (SSB) taxation published in eleven UK newspapers between 1 April 2015 and 30 November 2016, identified through the Nexis database. Direct stakeholder citations were entered in NVivo to allow inductive thematic analysis and comparison with an established typology of industry stakeholder arguments used by the alcohol and tobacco industries. SETTING: UK newspapers. PARTICIPANTS: Proponents and opponents of SSB tax/SDIL cited in UK newspapers. RESULTS: Four hundred and ninety-one newspaper articles cited stakeholders' (n 287) arguments in relation to SSB taxation (n 1761: 65 % supportive and 35 % opposing). Stakeholders' positions broadly reflected their vested interests. Inconsistencies arose from: changes in ideological position; insufficient clarity on the nature of the problem to be solved; policy priorities; and consistency with academic rigour. Both opposing and supportive themes were comparable with the alcohol and tobacco industry typology. CONCLUSIONS: Public health advocates were particularly prominent in the UK newspaper debate surrounding the SDIL. Advocates in future policy debates might benefit from seeking a similar level of prominence and avoiding inconsistencies by being clearer about the policy objective and mechanisms.

BACKGROUND: Excess sugar consumption, including sugar-sweetened beverages (SSBs), contributes to a variety of negative health outcomes, particularly for young people. The mass media play a powerful role in influencing public and policy-makers' perceptions of public health issues and their solutions. We analysed how sugar and SSB policy debates were presented in UK newspapers at a time of heightened awareness and following the announcement of the UK Government's soft drinks industry levy (SDIL), to inform future public health advocacy. METHODS & FINDINGS: We carried out quantitative content analysis of articles discussing the issues of sugar and SSB consumption published in 11 national newspapers from April 2015 to November 2016. 684 newspaper articles were analysed using a structured coding frame. Coverage peaked in line with evidence publication, campaigner activities and policy events. Articles predominantly supportive of SSB taxation (23.5%) outnumbered those that were predominantly oppositional (14.2%). However, oppositional articles outnumbered supportive ones in the month of the announcement of the SDIL. Sugar and SSB consumption were presented as health risks, particularly affecting young people, with the actions of industry often identified as the cause of the public health problem. Responsibility for addressing sugar overconsumption was primarily assigned to government intervention. CONCLUSION: Our results suggest that the policy landscape favouring fiscal solutions to curb sugar and SSB consumption has benefited from media coverage characterising the issue as an industry-driven problem. Media coverage may drive greater public acceptance of the SDIL and any future taxation of products containing sugar. However, future advocacy efforts should note the surge in opposition coinciding with the announcement of the SDIL, which echoes similar patterns of opposition observed in tobacco control debates.

Introduction: In this review, we highlight poor diet as the biggest risk factor for non-communicable diseases. We examine the denial tactics used by the food industry, how they reflect the tactics previously used by the tobacco industry, and how campaigners can use this knowledge to achieve future public health successes. Sources of data: Data sources are wide ranging, notably publications relating to public health, obesity and processed food, the effectiveness hierarchy and food industry denialism tactics. Areas of agreement: Global burden of disease analyses consistently demonstrate that poor diet produces a bigger burden of non-communicable disease than tobacco, alcohol and inactivity put together. The lessons learnt from the tobacco control experience of successfully fighting the tobacco industry can be applied to other industries including processed food and sugary drinks. Areas of controversy: Tackling obesity and poor diet is a more complex issue than tobacco. Food industries continue to promote weak or ineffective policies such as voluntary reformulation, and resist regulation and taxation. However, the UK food industry now faces increasing pressure from professionals, public and politicians to accept reformulation and taxes, or face more stringent measures. Growing points and areas timely for developing research: The rise in childhood and adult obesity needs to be arrested and then reversed. Unhealthy processed food and sugary drinks are a major contributing factor. There is increasing interest in the tactics being used by the food industry to resist change. Advocacy and activism will be essential to counter these denialism tactics and ensure that scientific evidence is translated into effective regulation and taxation.

OBJECTIVE: To systematically review published studies of interventions to reduce people's intake of dietary trans-fatty acids (TFAs). METHODS: We searched online databases (CINAHL, the CRD Wider Public Health database, Cochrane Database of Systematic Reviews, Ovid®, MEDLINE®, Science Citation Index and Scopus) for studies evaluating TFA interventions between 1986 and 2017. Absolute decrease in TFA consumption (g/day) was the main outcome measure. We excluded studies reporting only on the TFA content in food products without a link to intake. We included trials, observational studies, meta-analyses and modelling studies. We conducted a narrative synthesis to interpret the data, grouping studies on a continuum ranging from interventions targeting individuals to population-wide, structural changes. RESULTS: After screening 1084 candidate papers, we included 23 papers: 12 empirical and 11 modelling studies. Multiple interventions in Denmark achieved a reduction in TFA consumption from 4.5 g/day in 1976 to 1.5 g/day in 1995 and then virtual elimination after legislation banning TFAs in manufactured food in 2004. Elsewhere, regulations mandating reformulation of food reduced TFA content by about 2.4 g/day. Worksite interventions achieved reductions averaging 1.2 g/day. Food labelling and individual dietary counselling both showed reductions of around 0.8 g/day. CONCLUSION: Multicomponent interventions including legislation to eliminate TFAs from food products were the most effective strategy. Reformulation of food products and other multicomponent interventions also achieved useful reductions in TFA intake. By contrast, interventions targeted at individuals consistently achieved smaller reductions. Future prevention strategies should consider this effectiveness hierarchy to achieve the largest reductions in TFA consumption.

Background: A low intake of fruits and vegetables (F&Vs) is a major risk factor for cardiovascular disease (CVD) in the United States. Both mass media campaigns (MMCs) and economic incentives may increase F&V consumption. Few data exist on their comparative effectiveness.Objective: We estimated CVD mortality reductions potentially achievable by price reductions and MMC interventions targeting F&V intake in the US population.Design: We developed a US IMPACT Food Policy Model to compare 3 policies targeting F&V intake across US adults from 2015 to 2030: national MMCs and national F&V price reductions of 10% and 30%. We accounted for differences in baseline diets, CVD rates, MMC coverage, MMC duration, and declining effects over time. Outcomes included cumulative CVD (coronary heart disease and stroke) deaths prevented or postponed and life-years gained (LYGs) over the study period, stratified by age, sex, and race.Results: A 1-y MMC in 2015 would increase the average national F&V consumption by 7% for 1 y and prevent â¼18,600 CVD deaths (95% CI: 17,600, 19,500), gaining â¼280,100 LYGs by 2030. With a 15-y MMC, increased F&V consumption would be sustained, yielding a 3-fold larger reduction (56,100; 95% CI: 52,400, 57,700) in CVD deaths. In comparison, a 10% decrease in F&V prices would increase F&V consumption by â¼14%. This would prevent â¼153,300 deaths (95% CI: 146,400, 159,200), gaining â¼2.51 million LYGs. For a 30% price decrease, resulting in a 42% increase in F&V consumption, corresponding values would be 451,900 CVD deaths prevented or postponed (95% CI: 433,100, 467,500) and 7.3 million LYGs gained. Effects were similar by sex, with a smaller proportional effect and larger absolute effects at older ages. A 1-y MMC would be 35% less effective in preventing CVD deaths in non-Hispanic blacks than in whites. In comparison, price-reduction policies would have equitable proportional effects.Conclusion: Both national MMCs and price-reduction policies could reduce US CVD mortality, with price reduction being more powerful and sustainable.

BACKGROUND: Large socio-economic disparities exist in US dietary habits and cardiovascular disease (CVD) mortality. While economic incentives have demonstrated success in improving dietary choices, the quantitative impact of different dietary policies on CVD disparities is not well established. We aimed to quantify and compare the potential effects on total CVD mortality and disparities of specific dietary policies to increase fruit and vegetable (F&V) consumption and reduce sugar-sweetened beverage (SSB) consumption in the US. METHODS AND FINDINGS: Using the US IMPACT Food Policy Model and probabilistic sensitivity analyses, we estimated and compared the reductions in CVD mortality and socio-economic disparities in the US population potentially achievable from 2015 to 2030 with specific dietary policy scenarios: (a) a national mass media campaign (MMC) aimed to increase consumption of F&Vs and reduce consumption of SSBs, (b) a national fiscal policy to tax SSBs to increase prices by 10%, (c) a national fiscal policy to subsidise F&Vs to reduce prices by 10%, and (d) a targeted policy to subsidise F&Vs to reduce prices by 30% among Supplemental Nutrition Assistance Program (SNAP) participants only. We also evaluated a combined policy approach, combining all of the above policies. Data sources included the Surveillance, Epidemiology, and End Results Program, National Vital Statistics System, National Health and Nutrition Examination Survey, and published meta-analyses. Among the individual policy scenarios, a national 10% F&V subsidy was projected to be most beneficial, potentially resulting in approximately 150,500 (95% uncertainty interval [UI] 141,400-158,500) CVD deaths prevented or postponed (DPPs) by 2030 in the US. This far exceeds the approximately 35,100 (95% UI 31,700-37,500) DPPs potentially attributable to a 30% F&V subsidy targeting SNAP participants, the approximately 25,800 (95% UI 24,300-28,500) DPPs for a 1-y MMC, or the approximately 31,000 (95% UI 26,800-35,300) DPPs for a 10% SSB tax. Neither the MMC nor the individual national economic policies would significantly reduce CVD socio-economic disparities. However, the SNAP-targeted intervention might potentially reduce CVD disparities between SNAP participants and SNAP-ineligible individuals, by approximately 8% (10 DPPs per 100,000 population). The combined policy approach might save more lives than any single policy studied (approximately 230,000 DPPs by 2030) while also significantly reducing disparities, by approximately 6% (7 DPPs per 100,000 population). Limitations include our effect estimates in the model; these estimates use interventional and prospective observational studies (not exclusively randomised controlled trials). They are thus imperfect and should be interpreted as the best available evidence. Another key limitation is that we considered only CVD outcomes; the policies we explored would undoubtedly have additional beneficial effects upon other diseases. Further, we did not model or compare the cost-effectiveness of each proposed policy. CONCLUSIONS: Fiscal strategies targeting diet might substantially reduce CVD burdens. A national 10% F&V subsidy would save by far the most lives, while a 30% F&V subsidy targeting SNAP participants would most reduce socio-economic disparities. A combined policy would have the greatest overall impact on both mortality and socio-economic disparities.

BACKGROUND: Non-communicable disease (NCD) prevention strategies now prioritise four major risk factors: food, tobacco, alcohol and physical activity. Dietary salt intake remains much higher than recommended, increasing blood pressure, cardiovascular disease and stomach cancer. Substantial reductions in salt intake are therefore urgently needed. However, the debate continues about the most effective approaches. To inform future prevention programmes, we systematically reviewed the evidence on the effectiveness of possible salt reduction interventions. We further compared "downstream, agentic" approaches targeting individuals with "upstream, structural" policy-based population strategies. METHODS: We searched six electronic databases (CDSR, CRD, MEDLINE, SCI, SCOPUS and the Campbell Library) using a pre-piloted search strategy focussing on the effectiveness of population interventions to reduce salt intake. Retrieved papers were independently screened, appraised and graded for quality by two researchers. To facilitate comparisons between the interventions, the extracted data were categorised using nine stages along the agentic/structural continuum, from "downstream": dietary counselling (for individuals, worksites or communities), through media campaigns, nutrition labelling, voluntary and mandatory reformulation, to the most "upstream" regulatory and fiscal interventions, and comprehensive strategies involving multiple components. RESULTS: After screening 2,526 candidate papers, 70 were included in this systematic review (49 empirical studies and 21 modelling studies). Some papers described several interventions. Quality was variable. Multi-component strategies involving both upstream and downstream interventions, generally achieved the biggest reductions in salt consumption across an entire population, most notably 4g/day in Finland and Japan, 3g/day in Turkey and 1.3g/day recently in the UK. Mandatory reformulation alone could achieve a reduction of approximately 1.45g/day (three separate studies), followed by voluntary reformulation (-0.8g/day), school interventions (-0.7g/day), short term dietary advice (-0.6g/day) and nutrition labelling (-0.4g/day), but each with a wide range. Tax and community based counselling could, each typically reduce salt intake by 0.3g/day, whilst even smaller population benefits were derived from health education media campaigns (-0.1g/day). Worksite interventions achieved an increase in intake (+0.5g/day), however, with a very wide range. Long term dietary advice could achieve a -2g/day reduction under optimal research trial conditions; however, smaller reductions might be anticipated in unselected individuals. CONCLUSIONS: Comprehensive strategies involving multiple components (reformulation, food labelling and media campaigns) and "upstream" population-wide policies such as mandatory reformulation generally appear to achieve larger reductions in population-wide salt consumption than "downstream", individually focussed interventions. This 'effectiveness hierarchy' might deserve greater emphasis in future NCD prevention strategies.

BACKGROUND: A conflict of interest (CoI) can occur between public duty and private interest, in which a public official's private-capacity interest could improperly influence the performance of their official duties and responsibilities. The most tangible and commonly considered CoI are financial. However, CoI can also arise due to other types of influence including interpersonal relationships, career progression, or ideology. CoI thus exist in academia, business, government and non-governmental organisations. However, public knowledge of CoI is currently limited due to a lack of information. The mechanisms of managing potential conflicts of interest also remain unclear due to a lack of guidelines. We therefore examined the independence of academic experts and how well potential CoI are identified and addressed in four government and non-governmental organisations in the UK responsible for the development of food policy. METHODS: Policy analysis. We developed an analytical framework to explore CoI in high-level UK food policy advice, using four case studies. Two government policy-making bodies: Department of Health 'Obesity Review Group' (ORG), 'Scientific Advisory Committee on Nutrition' (SACN) and two charities: 'Action on Sugar' (AoS), & 'Heart of Mersey' (HoM). Information was obtained from publicly available sources and declarations. We developed a five point ordinal scale based upon the ideology of the Nolan Principles of Public Life. Group members were individually categorised on the ordinal ConScale from "0", (complete independence from the food and drink industry) to "4", (employed by the food and drink industry or a representative organisation). RESULTS: CoI involving various industries have long been evident in policy making, academia and clinical practice. Suggested approaches for managing CoI could be categorised as "deny", "describe", or "diminish". Declared CoI were common in the ORG and SACN. 4 out of 28 ORG members were direct industry employees. In SACN 11 out of 17 members declared industry advisory roles or industry research funding. The two charities appeared to have equally strong academic expertise but fewer conflicts. No HoM members declared CoI. 5 out of 21 AoS members declared links with industry, mainly pharmaceutical companies. We were unable to obtain information on conflicts for some individuals. CONCLUSIONS: Conflicts of interest are unavoidable but potentially manageable. Government organisations responsible for policy development and implementation must institutionalize an approach to identify (disclose) and manage (mitigate or eliminate) perceived and actual CoI to improve public confidence in government decision-making relevant to food policy.

OBJECTIVES: To assess the extent of media-based public health advocacy versus pro-industry messaging regarding sugar-sweetened beverages (SSBs). DESIGN: We conducted a systematic analysis to identify and examine all articles regarding SSBs published in all mainstream British print newspapers and their online news websites from 1 January 2014 to 31 December 2014. We initially conducted a brief literature search to develop appropriate search terms and categorisations for grouping and analysing the articles. Articles were then coded according to the publishing newspaper, article type, topic, prominence and slant (pro-SSB or anti-SSB). A contextual analysis was undertaken to examine key messages in the articles. RESULTS: We identified 374 articles published during 2014. The majority of articles (81%) suggested that SSBs are unhealthy. Messaging from experts, campaign groups and health organisations was fairly consistent about the detrimental effects of SSB on health. However, relatively few articles assessed any approaches or solutions to potentially combat the problems associated with SSBs. Only one-quarter (24%) suggested any policy change. Meanwhile, articles concerning the food industry produced consistent messages emphasising consumer choice and individual responsibility for making choices regarding SSB consumption, and promoting and advertising their products. The food industry thus often managed to avoid association with the negative press that their products were receiving. CONCLUSIONS: SSBs were frequently published in mainstream British print newspapers and their online news websites during 2014. Public health media advocacy was prominent throughout, with a growing consensus that sugary drinks are bad for people's health. However, the challenge for public health will be to mobilise supportive public opinion to help implement effective regulatory policies. Only then will our population's excess consumption of SSBs come under control.

OBJECTIVE: To investigate the amount of sugars in fruit juices, juice drinks and smoothies (FJJDS) marketed to children. DESIGN: We surveyed the sugars content (per 100 ml and standardised 200 ml portion) of all FJJDS sold by seven major UK supermarkets (supermarket own and branded products). Only products specifically marketed towards children were included. We excluded sports drinks, iced teas, sugar-sweetened carbonated drinks and cordials as being not specifically marketed towards children. RESULTS: We identified 203 fruit juices (n=21), juice drinks (n=158) and smoothies (n=24) marketed to children. Sugars content ranged from 0 to 16 g/100 ml. The mean sugars content was 7.0 g/100 ml, but among the 100% fruit juice category, it was 10.7 g/100 ml. Smoothies (13.0 g/100 ml) contained the highest amounts of sugars and juice drinks (5.6 g/100 ml) contained the lowest amount. 117 of the 203 FJJDS surveyed would receive a Food Standards Agency 'red' colour-coded label for sugars per standardised 200 ml serving. Only 63 FJJDS would receive a 'green' colour-coded label. 85 products contained at least 19 g of sugars-a child's entire maximum daily amount of sugars. 57 products contained sugar (sucrose), 65 contained non-caloric sweeteners and five contained both. Seven products contained glucose-fructose syrup. CONCLUSIONS: The sugars content in FJJDS marketed to children in the UK is unacceptably high. Manufacturers must stop adding unnecessary sugars and calories to their FJJDS.
