Inequalities in research on food environment policies: An evidence map of global evidence from 2010-2020.

BACKGROUND: There has been increasing pressure to implement policies for promoting healthy food environments worldwide. OBJECTIVE: This evidence map critically explored the breadth and nature of primary research from 2010-2020 evaluating the effectiveness, cost-effectiveness, development, and implementation of mandatory and voluntary food environment policies. METHODS: 'Real-world' evaluations of international, national and state level policies promoting healthy food environments, published between 2010 and 2020, were searched across 14 databases and two websites. We documented the policy and evaluation characteristics, including the International WCRF NOURISHING framework's policy categories and ten equity characteristics using the PROGRESS-Plus framework. Data were synthesised using descriptive statistics and visuals. RESULTS: We screened 27,958 records, of which 482 were included. Although these covered 70 countries, 81% of publications focused on only 12 countries (USA, UK, Australia, Canada, Mexico, Brazil, Chile, France, Spain, Denmark, New Zealand and South Africa). Studies from these countries employed more robust quantitative methods and included most of the evaluations of policy development, implementation, and cost-effectiveness. Few publications reported on Africa (n=12), Central and South Asia (n=5), and the Middle East (n=6) regions. Few also assessed public-private partnerships (PPPs, n=31, 6%) compared to voluntary approaches by the private sector (n=96, 20%), the public sector (n=90, 19%), and mandatory approaches (n=288, 60%). Most evaluations of PPPs were about two partnerships. Only 50% of publications assessing policy effectiveness compared outcomes between population groups stratified by an equity characteristic, and this proportion has decreased over time. CONCLUSIONS: There are striking inequities in the origin, scope and design of these studies, suggesting that research capacity and funding lies in the hands of a few expert teams worldwide. The small number of studies on PPPs questions the evidence base underlying the international push for PPPs to promote health. Policy evaluations should consider impacts on equity more consistently.

The effectiveness, cost-effectiveness and policy processes of regulatory, voluntary and partnership policies to improve food environments: an evidence synthesis.

Background: Dietary factors are among the largest and costliest drivers of chronic diseases in England. As a response, the government implements a range of population interventions to promote healthy diets by targeting food environments. Objectives: This study aimed to conduct a systematic review of the effectiveness, cost-effectiveness and policy process of real-world evaluations of national and state policies on improving food environments, with a focus on whether they were regulatory, voluntary or partnership approaches. Data sources: Fourteen relevant English-language databases were searched in November 2020 for studies published between 2010 and 2020. Methods: Six separate evidence reviews were conducted to assess the evidence of effectiveness, cost-effectiveness and policy processes of policies to improve food environments. Results: A total of 483 primary research evaluations and 14 evidence syntheses were included. The study reveals considerable geographic, methodological and other imbalances across the literature, with, for example, 81% of publications focusing only on 12 countries. The systematic reviews also reveal the effectiveness and cost-effectiveness of reviewed regulatory approaches designed to improve health, consumer behaviour and food environment outcomes while public-private partnerships and voluntary approaches to improve diets via reformulation, advertising and promotion restrictions or other changes to the environment were limited in their effectiveness and cost-effectiveness. The study also revealed key enabling and impeding factors across regulatory, voluntary and public-private partnership approaches. Conclusion: From the available evidence reviewed, this study finds that regulatory approaches appear most effective at improving the food environment, and voluntary agreements and partnerships have limited effectiveness. These findings should be carefully considered in future public health policy development, as should the findings of geographic imbalance in the evidence and inadequate representation of equity dimensions across the policy evaluations. We find that food policies are at times driven by factors other than the evidence and shaped by compromise and pragmatism. Food policy should be first and foremost designed and driven by the evidence of greatest effectiveness to improve food environments for healthier diets. Limitations: This was a complex evidence synthesis due to its scope and some policy evaluations may have been missed as the literature searches did not include specific policy names. The literature was limited to studies published in English from 2010 to 2020, potentially missing studies of interest. Future work: Priorities include the need for guidance for appraising risk of bias and quality of non-clinical studies, for reporting policy characteristics in evaluations, for supporting evaluations of real-world policies equitably across geographic regions, for capturing equity dimensions in policy evaluations, and for guideline development for quality and risk of bias of policy evaluations.

Poor diet is a leading cause of death, globally, including in the United Kingdom. It also causes many types of illness and is one of the biggest drains on the United Kingdom National Health Service budget. Governments act in various ways to promote healthy diets by improving food environments: these are the physical and social surroundings that influence what and how much people eat. Some actions are regulated by government, for example, to control food production, marketing and promotions. Other actions are led by, or with, food businesses, making voluntary changes to the foods they produce, for example, by reducing salt content; this can be done by businesses alone or in partnership with government (referred to as 'public­private partnerships'). The six reviews of published research look at whether, and how, these actions to improve diets work, and whether they can provide value for money. Most regulations appear to be effective at supporting better diets. However, voluntary changes led by businesses had limited success. There were not many evaluations that assessed the effectiveness of public­private partnerships. Of those that did, partnerships with the food industry had limited effectiveness, resulting in largely unchanged outcomes. When looking at how these actions improve diets, we found that clear leadership, public support for the policy, the use of the best evidence and of local expertise helped with getting actions implemented. Factors that appear to make it harder to implement policy actions include a lack of evidence specific to the context, conflicting beliefs about what works, limited human or financial resources, lack of engagement by key people. Although the findings may help us to think about the ways forward to improve diets, more research is needed to understand whether actions to reduce diet-related ill health work, and provide value for money.

Young people's views and experience of diet-related inequalities in England (UK): a qualitative study.

Inequalities in diets contribute to overall inequalities in health. Economic inequality and inequalities in access to healthy food are key drivers of poor diet and ill health among young people (YP). Despite mounting evidence of structural barriers to healthy eating, less is known about how YP view and experience these inequalities where they live, and how to address them. To explore YP's perspectives on the drivers of diet-related health inequalities, we conducted three interlinked focus groups with YP aged 13-21 years from six youth groups across three geographical areas in England. We analysed the data inductively and deductively using reflexive thematic analysis and generated themes by examining how social structure, context and agency interact and impact YP's diet. YP were aware of how inequalities in employment conditions impact their families' income and ability to eat a healthy diet. They cited the high availability of hot food takeaways in their local areas as a significant barrier to healthy eating but did not support closing or restricting these outlets. They held strong views on policies to tackle diet inequality and showed a nuanced understanding of the strengths and limitations of universal and targeted approaches. Our study showed that YP have an awareness and understanding of food as important in relation to health, and of diet-related inequalities. However, further efforts are needed to shape and promote policies that resonate with YP and address both their health and wider social concerns.

'It depends on where you were born here in the North East, there's not really many job opportunities compared to in the South': young people's perspectives on a North-South health divide and its drivers in England, UK.

BACKGROUND: Improving the public's understanding of how regional and socioeconomic inequalities create and perpetuate inequalities in health, is argued to be necessary for building support for policies geared towards creating a more equal society. However, research exploring public perceptions of health inequalities, and how they are generated, is limited. This is particularly so for young people. Our study sought to explore young people's lived experiences and understandings of health inequalities. METHODS: We carried out focus group discussions (n = 18) with 42 young people, aged 13-21, recruited from six youth organisations in England in 2021. The organisations were located in areas of high deprivation in South Yorkshire, the North East and London. Young people from each organisation took part in three interlinked focus group discussions designed to explore their (i) perceptions of factors impacting their health in their local area, (ii) understandings of health inequalities and (iii) priorities for change. Due to the Covid-19 pandemic, most discussions took place online (n = 15). However, with one group in the North East, we carried out discussions face-to-face (n = 3). Data were analysed thematically and we used NVivo-12 software to facilitate data management. RESULTS: Young people from all groups demonstrated an awareness of a North-South divide in England, UK. They described how disparities in local economies and employment landscapes between the North and the South led to tangible differences in everyday living and working conditions. They clearly articulated how these differences ultimately led to inequalities in people's health and wellbeing, such as linking poverty and employment precarity to chronic stress. Young people did not believe these inequalities were inevitable. They described the Conservative government as prioritising the South and thus perpetuating inequalities through uneven investment. CONCLUSIONS: Our study affords important insights into young people's perceptions of how wider determinants can help explain the North-South health divide in England. It demonstrates young people's contextualised understandings of the interplay between spatial, social and health inequalities. Our findings support calls for pro-equity policies to address the structural causes of regional divides in health. Further research, engaging young people in deliberative policy analysis, could build on this work.

Does better than expected life expectancy in areas of disadvantage indicate health resilience? Stakeholder perspectives and possible explanations.

Some places have better than expected health trends despite being disadvantaged in other ways. Thematic analysis of qualitative data from stakeholders (N = 25) in two case studies of disadvantaged local authorities the North West and South East of England assessed explanations for the localities' apparent health resilience. Participants identified ways of working that might contribute to improved life expectancy, such as partnering with third sector, targeting and outcome driven action. Stakeholders were reluctant to assume credit for better-than-expected health outcomes. External factors such as population change, national politics and finances were considered crucial. Local public health stakeholders regard their work as important but unlikely to cause place-centred health resilience.

Factors influencing public health engagement in alcohol licensing in England and Scotland including legal and structural differences: comparative interview analysis.

Background: Greater availability of alcohol is associated with higher consumption and harms. The legal systems, by which premises are licensed to sell alcohol in England and Scotland, differ in several ways. The 'Exploring the impact of alcohol licensing in England and Scotland' study measured public health team activity regarding alcohol licensing from 2012 to 2019 and identified seven differences between England and Scotland in the timing and type of activities undertaken. Objectives: To qualitatively describe the seven previously identified differences between Scotland and England in public health approaches to alcohol licensing, and to examine, from the perspective of public health professionals, what factors may explain these differences. Methods: Ninety-four interviews were conducted with 52 professionals from 14 English and 6 Scottish public health teams selected for diversity who had been actively engaging with alcohol licensing. Interviews focused primarily on the nature of their engagement (n = 66) and their rationale for the approaches taken (n = 28). Interview data were analysed thematically using NVivo. Findings were constructed by discussion across the research team, to describe and explain the differences in practice found. Findings: Diverse legal, practical and other factors appeared to explain the seven differences. (1) Earlier engagement in licensing by Scottish public health teams in 2012-3 may have arisen from differences in the timing of legislative changes giving public health a statutory role and support from Alcohol Focus Scotland. (2) Public Health England provided significant support from 2014 in England, contributing to an increase in activity from that point. (3) Renewals of statements of licensing policy were required more frequently in Scotland and at the same time for all Licensing Boards, probably explaining greater focus on policy in Scotland. (4) Organisational structures in Scotland, with public health stakeholders spread across several organisations, likely explained greater involvement of senior leaders there. (5) Without a public health objective for licensing, English public health teams felt less confident about making objections to licence applications without other stakeholders such as the police, and instead commonly negotiated conditions on licences with applicants. In contrast, Scottish public health teams felt any direct contact with applicants was inappropriate due to conflicts of interest. (6) With the public health objective in Scotland, public health teams there were more active in making independent objections to licence applications. Further in Scotland, licensing committee meetings are held to consider all new applications regardless of whether objections have been submitted; unlike in England where there was a greater incentive to resolve objections, because then a meeting was not required. (7) Finally, Scottish public health teams involved the public more in licensing process, partly because of statutory licensing forums there. Conclusions: The alcohol premises licensing systems in England and Scotland differ in important ways including and beyond the lack of a public health objective for licensing in England. These and other differences, including support of national and local bodies, have shaped opportunities for, and the nature of, public health engagement. Further research could examine the relative success of the approaches taken by public health teams and how temporary increases in availability are handled in the two licensing systems.

When alcohol becomes more widely available, harms tend to increase. In England and Scotland, this availability is controlled by local councils. They 'licence' shops, bars and other venues to allow them to sell alcohol. Local health teams, including doctors, often advise councils on licensing. In earlier work, we found seven differences in what Scottish and English health teams do on licensing. In this study, we explore these seven differences and why they came about. To do this, we interviewed 94 professionals working in public health across both countries. Scottish health teams got involved in licensing earlier than in England. This was partly because of when certain laws changed. Also, they were helped earlier by national organisations that try to reduce harm from alcohol. Scottish teams were more involved in local policies on licensing. This was probably because these policies changed more often in the Scottish system. Scottish teams involved the public more. This was partly because Scottish councils must set up 'local licensing forums'. Scottish teams also objected more often to licence applications. They generally felt that they could be more actively involved, because of a law in Scotland that says licensing must protect public health. This law does not apply in England. In England, health teams were more likely to talk to businesses that wanted licences. They were less likely to try to block applications. When they agreed changes to applications with businesses instead of objecting, fewer formal licensing meetings were needed. This was not the case in Scotland. Also, Scottish teams did not feel it was okay for them to talk to businesses. In summary, there are important differences in licensing law between Scotland and England. These matter for how health teams in the two countries engage with local councils, businesses and the public on licensing matters.

Public health engagement in alcohol licensing in England and Scotland: the ExILEnS mixed-method, natural experiment evaluation.

Background: International systematic reviews suggest an association between alcohol availability and increased alcohol-related harms. Alcohol availability is regulated through separate locally administered licensing systems in England and Scotland, in which local public health teams have a statutory role. The system in Scotland includes a public health objective for licensing. Public health teams engage to varying degrees in licensing matters but no previous study has sought to objectively characterise and measure their activity, examine their effectiveness, or compare practices between Scotland and England. Aim: To critically assess the impact and mechanisms of impact of public health team engagement in alcohol premises licensing on alcohol-related harms in England and Scotland. Methods: We recruited 39 diverse public health teams in England (n = 27) and Scotland (n = 12). Public health teams more active in licensing were recruited first and then matched to lower-activity public health teams. Using structured interviews (n = 66), documentation analysis, and expert consultation, we developed and applied the Public Health Engagement In Alcohol Licensing (PHIAL) measure to quantify six-monthly activity levels from 2012 to 2019. Time series of PHIAL scores, and health and crime outcomes for each area, were analysed using multivariable negative binomial mixed-effects models to assess correlations between outcome and exposure, with 18-month average PHIAL score as the primary exposure metric. In-depth interviews (n = 53) and a workshop (n = 10) explored public health team approaches and potential mechanisms of impact of alcohol availability interventions with public health team members and licensing stakeholders (local authority licensing officers, managers and lawyers/clerks, police staff with a licensing remit, local elected representatives). Findings: Nineteen public health team activity types were assessed in six categories: (1) staffing; (2) reviewing and (3) responding to licence applications; (4) data usage; (5) influencing licensing stakeholders/policy; and (6) public involvement. Usage and intensity of activities and overall approaches varied within and between areas over time, including between Scotland and England. The latter variation could be explained by legal, structural and philosophical differences, including Scotland's public health objective. This objective was felt to legitimise public health considerations and the use of public health data within licensing. Quantitative analysis showed no clear evidence of association between level of public health team activity and the health or crime outcomes examined, using the primary exposure or other metrics (neither change in, nor cumulative, PHIAL scores). Qualitative data suggested that public health team input was valued by many licensing stakeholders, and that alcohol availability may lead to harms by affecting the accessibility, visibility and norms of alcohol consumption, but that the licensing systems have limited power to act in the interests of public health. Conclusions: This study provides no evidence that public health team engagement in local licensing matters was associated with measurable downstream reductions in crime or health harms, in the short term, or over a 7-year follow-up period. The extensive qualitative data suggest that public health team engagement is valued and appears to be slowly reorienting the licensing system to better address health (and other) harms, especially in Scotland, but this will take time. A rise in home drinking, alcohol deliveries, and the inherent inability of the licensing system to reduce - or in the case of online sales, to contain - availability, may explain the null findings and will continue to limit the potential of these licensing systems to address alcohol-related harms. Future work: Further analysis could consider the relative success of different public health team approaches in terms of changing alcohol availability and retailing. A key gap relates to the nature and impact of online availability on alcohol consumption, harms and inequalities, alongside development and study of relevant policy options. A national approach to licensing data and oversight would greatly facilitate future studies and public health input to licensing. Limitations: Our interview data and therefore PHIAL scores may be limited by recall bias where documentary evidence of public health activity was not available, and by possible variability in grading of such activity, though steps were taken to minimise both. The analyses would have benefited from additional data on licensing policies and environmental changes that might have affected availability or harms in the study areas. Study registration: The study was registered with the Research Registry (researchregistry6162) on 26 October 2020. The study protocol was published in BMC Medical Research Methodology on 6 November 2018.

Research finds that when alcohol is more easily available, because more places sell alcohol or have longer opening hours, people tend to drink more and harms tend to increase. In England and Scotland, 'Licensing Committees' in local governments have power over which venues are given a licence to sell alcohol legally. They make decisions based on local policy and on licensing goals set out in law. Licensing laws are slightly different in both nations, and health representatives are often involved in trying to influence local licensing decisions and policies, to reduce alcohol-related harms. We aimed to find out what public health teams have done to influence alcohol licensing and whether their actions have affected alcohol-related harms. We recruited 39 public health teams (Scotland: 12; England: 27) and measured how active they were on licensing matters. We gathered detailed information (from interviews and papers) about their actions from 2012 to 2019, and asked them and others involved in licensing (including police, and local authority licensing teams and lawyers) about how their efforts might make a difference to harms. We gathered local data on alcohol-related health harms and crimes during 2009­19. We analysed whether any changes in these harms were related to the level of public health team activity, and explored differences between Scotland and England. Public health teams across Scotland and England took varied approaches to engaging in alcohol licensing, and their work was often welcomed by others working in the licensing system. However, we found no clear relationship between the level of licensing-related activity that public health teams engaged in and the levels of alcohol-related health harms or crime. This may be because their actions make only a modest difference to licensing decisions, or because it may take longer than the study period for them to have a sizeable impact. Reducing alcohol-related harms through licensing may require strengthening national licensing laws and the powers of public health teams, including by addressing online sales and home deliveries.

Investigating health and social outcomes of the Big Local community empowerment initiative in England: a mixed method evaluation.

Background: Most research on community empowerment provides evidence on engaging communities for health promotion purposes rather than attempts to create empowering conditions. This study addresses this gap. Intervention: Big Local started in 2010 with £271M from the National Lottery. Ending in 2026, it gives 150 relatively disadvantaged communities in England control over £1M to improve their neighbourhoods. Objective: To investigate health and social outcomes, at the population level and among engaged residents, of the community engagement approach adopted in a place-based empowerment initiative. Study design, data sources and outcome variables: This study reports on the third wave of a longitudinal mixed-methods evaluation. Work package 1 used a difference-in-differences design to investigate the impact of Big Local on population outcomes in all 150 Big Local areas compared to matched comparator areas using secondary data. The primary outcome was anxiety; secondary outcomes included a population mental health measure and crime in the neighbourhood. Work package 2 assessed active engagement in Big Local using cross-sectional data and nested cohort data from a biannual survey of Big Local partnership members. The primary outcome was mental well-being and the secondary outcome was self-rated health. Work package 3 conducted qualitative research in 14 Big Local neighbourhoods and nationally to understand pathways to impact. Work package 4 undertook a cost-benefit analysis using the life satisfaction approach to value the benefits of Big Local, which used the work package 1 estimate of Big Local impact on life satisfaction. Results: At a population level, the impacts on 'reporting high anxiety' (-0.8 percentage points, 95% confidence interval -2.4 to 0.7) and secondary outcomes were not statistically significant, except burglary (-0.054 change in z-score, 95% confidence interval -0.100 to -0.009). There was some effect on reduced anxiety after 2017. Areas progressing fastest had a statistically significant reduction in population mental health measure (-0.053 change in z-score, 95% confidence interval -0.103 to -0.002). Mixed results were found among engaged residents, including a significant increase in mental well-being in Big Local residents in the nested cohort in 2018, but not by 2020; this is likely to be COVID-19. More highly educated residents, and males, were more likely to report a significant improvement in mental well-being. Qualitative accounts of positive impacts on mental well-being are often related to improved social connectivity and physical/material environments. Qualitative data revealed increasing capabilities for residents' collective control. Some negative impacts were reported, with local factors sometimes undermining residents' ability to exercise collective control. Finally, on the most conservative estimate, the cost-benefit calculations generate a net benefit estimate of £64M. Main limitations: COVID-19 impacted fieldwork and interpretation of survey data. There was a short 4-year follow-up (2016/20), no comparators in work package 2 and a lack of power to look at variations across areas. Conclusions: Our findings suggest the need for investment to support community organisations to emerge from and work with communities. Residents should lead the prioritisation of issues and design of solutions but not necessarily lead action; rather, agencies should work as equal partners with communities to deliver change.

The Communities in Control study is looking at the health impacts of the Big Local community empowerment programme, funded by the National Lottery Community Fund and managed by Local Trust (a national charitable organisation). Residents of 150 English areas have at least £1M and other support to improve the neighbourhoods. There have been three phases of the research. This report shares findings from their third phase, which began in 2018. First, we used data from a national survey and data from national health and welfare services to compare changes in mental health between people living in Big Local areas and those in similar areas that did not have a Big Local partnership. Furthermore, we also used publicly available data on crime in the neighbourhoods. We found weak evidence that Big Local was linked with improved mental health and a reduction in burglaries. Second, we used data from a survey conducted by Local Trust to look at health and social impacts on the most active residents. We found an increase in mental well-being in 2018 but this was not maintained in 2020, probably due to the COVID-19 pandemic. Third, we did interviews and observations in 14 Big Local areas to understand what helps and what does not help residents to improve their neighbourhoods. We found that partnerships need to have legitimacy, the right balance of support, and learning opportunities. Residents suggested that creating social connections and welcoming social spaces, improving how people view the area and tackling poverty contributed to health improvements. Direct involvement in Big Local was both stressful and rewarding. Finally, we did a cost­benefit analysis by putting a monetary value on residents' increase in life satisfaction due to Big Local and comparing it with the costs of Big Local. We found that the benefits exceed the costs by at least £60M, suggesting that Big Local provides good value for money.

Systems Thinking and Complexity Science Methods and the Policy Process in Non-communicable Disease Prevention: A Systematic Scoping Review.

BACKGROUND: Given the complex determinants of non-communicable diseases (NCDs), and the dynamic policy landscape, researchers and policymakers are exploring the use of systems thinking and complexity science (STCS) in developing effective policies. The aim of this review is to systematically identify and analyse existing applications of STCS-informed methods in NCD prevention policy. METHODS: Systematic scoping review: We searched academic databases (Medline, Scopus, Web of Science, EMBASE) for all publications indexed by 13 October 2020, screening titles, abstracts and full texts and extracting data according to published guidelines. We summarised key data from each study, mapping applications of methods informed by STCS to policy process domains. We conducted a thematic analysis to identify advantages, limitations, barriers and facilitators to using STCS. RESULTS: 4681 papers were screened and 112 papers were included in this review. The most common policy areas were tobacco control, obesity prevention and physical activity promotion. Methods applied included system dynamics modelling, agent-based modelling and concept mapping. Advantages included supporting evidence-informed decision-making; modelling complex systems and addressing multi-sectoral problems. Limitations included the abstraction of reality by STCS methods, despite aims of encompassing greater complexity. Challenges included resource-intensiveness; lack of stakeholder trust in models; and results that were too complex to be comprehensible to stakeholders. Ensuring stakeholder ownership and presenting findings in a user-friendly way facilitated STCS use. CONCLUSION: This review maps the proliferating applications of STCS methods in NCD prevention policy. STCS methods have the potential to generate tailored and dynamic evidence, adding robustness to evidence-informed policymaking, but must be accessible to policy stakeholders and have strong stakeholder ownership to build consensus and change stakeholder perspectives. Evaluations of whether, and under what circumstances, STCS methods lead to more effective policies compared to conventional methods are lacking, and would enable more targeted and constructive use of these methods.

Natural experiments for the evaluation of place-based public health interventions: a methodology scoping review.

Introduction: Place-based public health evaluations are increasingly making use of natural experiments. This scoping review aimed to provide an overview of the design and use of natural experiment evaluations (NEEs), and an assessment of the plausibility of the as-if randomization assumption. Methods: A systematic search of three bibliographic databases (Pubmed, Web of Science and Ovid-Medline) was conducted in January 2020 to capture publications that reported a natural experiment of a place-based public health intervention or outcome. For each, study design elements were extracted. An additional evaluation of as-if randomization was conducted by 12 of this paper's authors who evaluated the same set of 20 randomly selected studies and assessed 'as-if ' randomization for each. Results: 366 NEE studies of place-based public health interventions were identified. The most commonly used NEE approach was a Difference-in-Differences study design (25%), followed by before-after studies (23%) and regression analysis studies. 42% of NEEs had likely or probable as-if randomization of exposure (the intervention), while for 25% this was implausible. An inter-rater agreement exercise indicated poor reliability of as-if randomization assignment. Only about half of NEEs reported some form of sensitivity or falsification analysis to support inferences. Conclusion: NEEs are conducted using many different designs and statistical methods and encompass various definitions of a natural experiment, while it is questionable whether all evaluations reported as natural experiments should be considered as such. The likelihood of as-if randomization should be specifically reported, and primary analyses should be supported by sensitivity analyses and/or falsification tests. Transparent reporting of NEE designs and evaluation methods will contribute to the optimum use of place-based NEEs.

Inequalities in local government spending on cultural, environmental and planning services: a time-trend analysis in England, Scotland, and Wales.

BACKGROUND: Local government provides Cultural, Environmental, and Planning (CEP) services, such as parks, libraries, and waste collection, that are vital for promoting health and wellbeing. There have been significant changes to the funding of these services over the past decade, most notably due to the UK government's austerity programme. These changes have not affected all places equally. To understand potential impacts on health inequalities, we investigated geographical patterning of recent CEP spending trends. METHODS: We conducted a time trend analysis using routinely available data on local government expenditure. We used generalised estimating equations to determine how expenditure trends varied across 378 local authorities (LAs) in Great Britain between 2009/10 and 2018/19 on the basis of country, deprivation, rurality, and local government structure. We investigated the gross expenditure per capita on CEP services, and the CEP expenditure as a proportion of total local authority budgets. We present the estimated annual percentage change in these spend measures. RESULTS: Expenditure per capita for CEP services reduced by 36% between 2009/10 and 2018/19. In England, the reduction in per capita spending was steepest in the most deprived quintile of areas, falling by 7.5% [95% CI: 6.0, 8.9] per year, compared to 4.5% [95% CI: 3.3, 5.6] per year in the least deprived quintile. Budget cuts in Scotland and Wales have been more equitable, with similar trends in the most and least deprived areas. Welsh LAs have reduced the proportion of total LA budget spent on CEP services the most (-4.0% per year, 95% CI: -5.0 to -2.9), followed by Scotland (-3.0% per year, 95% CI: -4.2 to -1.7) then England (-1.4% per year, 95% CI: -2.2 to -0.6). In England, rural and unitary LAs reduced their share of spending allocated to CEP more than urban and two-tier structured LAs, respectively. CONCLUSION: Funding for cultural, environmental and planning services provided by local government in the UK has been cut dramatically over the last decade, with clear geographical inequalities. Local areas worst affected have been those with a higher baseline level of deprivation, those with a single-tier local government structure, and English rural local authorities. The inequalities in cuts to these services risk widening geographical inequalities in health and wellbeing.

Measuring How Public Health Stakeholders Seek to Influence Alcohol Premises Licensing in England and Scotland: The Public Health Engagement In Alcohol Licensing (PHIAL) Measure.

OBJECTIVE: In the United Kingdom, some public health teams (PHTs) routinely engage with local alcohol premises licensing systems, through which licenses to sell alcohol are granted. We aimed to categorize PHT efforts and to develop and apply a measure of their efforts over time. METHOD: Preliminary categories of PHT activity were developed based on prior literature and were used to guide data collection with PHTs in 39 local government areas (27 in England; 12 in Scotland), sampled purposively. Relevant activity from April 2012 to March 2019 was identified through structured interviews (N = 62), documentation analysis, and follow-up checks, and a grading system was developed. The measure was refined based on expert consultation and used to grade relevant PHT activity for the 39 areas in 6-month periods. RESULTS: The Public Health engagement In Alcohol Licensing (PHIAL) Measure includes 19 activities in six categories: (a) staffing; (b) reviewing license applications; (c) responding to license applications; (d) data usage; (e) influencing licensing stakeholders or policy; and (f) public involvement. PHIAL scores for each area demonstrate fluctuation in type and level of activity between and within areas over time. Participating PHTs in Scotland were more active on average, particularly on senior leadership, policy development, and working with the public. In England, activity to influence license applications before decision was more common, and a clear increase in activity is apparent from 2014 onward. CONCLUSIONS: The novel PHIAL Measure successfully assessed diverse and fluctuating PHT engagement in alcohol licensing systems over time and will have practice, policy, and research applications.

Impact of selective licensing schemes for private rental housing on mental health and social outcomes in Greater London, England: a natural experiment study.

OBJECTIVES: To assess primary impact of selective Licensing (SL), an area-based intervention in the private rented housing market, on individual self-reported anxiety and neighbourhood mental health (MHI-Mental Healthcare Index) and secondary impacts on antisocial behaviour (ASB), population turnover and self-reported well-being. DESIGN: Difference-in-difference (DiD) was used to evaluate effects of SL schemes initiated 2012-2018. 921 intervention areas (lower super output areas) were matched 3:1 using propensity scores derived from sociodemographic and housing variables (N=3.684 including controls). Average treatment effect on treated (ATT) was calculated for multiple time period DiD in area-level analyses. Canonical DiD was used for individual-level analysis by year of treatment initiation while adjusting for age, sex, native birth and occupational class. SETTING: Intervention neighbourhoods and control areas in Greater London, UK, 2011-2019. PARTICIPANTS: We sampled 4474 respondents renting privately in intervention areas (N=17 347 including controls) in Annual Population Survey and obtained area-level MHI population data. INTERVENTIONS: Private landlords in SL areas must obtain a licence from the local authority, allow inspection and maintain minimum housing standards. RESULTS: ATT after 5 years was significantly lower for MHI (-7.5%, 95% CI -5.6% to -8.8%) than controls. Antidepressant treatment days per population reduced by -5.4% (95% CI -3.7% to -7.3), mental health benefit receipt by -9.6% (95% CI -14% to -5.5%) and proportion with depression by -12% (95% CI -7.7% to -16.3%). ASB reduced by -15% (95% CI -21% to -8.2%). Population turnover increased by 26.5% (95% CI 22.1% to 30.8%). Sensitivity analysis suggests overlap with effects of London 2012 Olympic regeneration. No clear patterns were observed for self-reported anxiety. CONCLUSIONS: We found associations between SL and reductions in area-based mental healthcare outcomes and ASB, while population turnover increased. A national evaluation of SL is feasible and necessary.

Use of e-Cigarettes and Attendance at Stop Smoking Services: A Population Survey in England.

Little is known about whether e-cigarette use influences tobacco smokers' decisions around other smoking cessation options, including the most effective one available: stop smoking service (SSS) attendance. Our repeat cross-sectional survey therefore assessed associations between use of e-cigarettes with past and planned future uptake of SSSs. Nicotine replacement therapy (NRT) use was also assessed as a comparator. Participants were drawn from the Smoking Toolkit Study, a nationally representative, validated, face-to-face survey. Data were aggregated on 2139 English adults reporting current smoking of cigarettes or other tobacco products. Multivariable logistic regression was used to adjust for potential confounders. Results showed dual users of combustible tobacco and e-cigarettes were more likely than other smokers to report having accessed SSSs in the past (AOR 1.43, 95% CI 1.08 to 1.90) and intending to take up these services in future (AOR 1.51, 95% CI 1.14 to 2.00). Dual users of combustible tobacco and NRT showed similar associations. Secondary objectives provided evidence on key psychosocial factors that influenced smokers' decision-making in this area. In summary, despite speculation that e-cigarette use might deter smokers from accessing SSSs, our study found dual users of tobacco and e-cigarettes were more likely to report uptake of such services, compared to smokers not using e-cigarettes.

Addressing alcohol-related harms in the local night-time economy: a qualitative process evaluation from a complex systems perspective.

OBJECTIVES: English local authorities (LAs) are interested in reducing alcohol-related harms and may use discretionary powers such as the Late Night Levy (LNL) to do so. This study aims to describe how system stakeholders hypothesise the levy may generate changes and to explore how the system, its actors and the intervention adapt and co-evolve over time. DESIGN: A process evaluation from a complex systems perspective, using qualitative methods. SETTING: A London LA with high densities of residential and commercial properties, which implemented the LNL in 2014. PARTICIPANTS: Data were generated through interviews with LNL implementers and alcohol consumers, observations in bars and during LNL patrols and documentary review. INTERVENTION: The LNL allows LAs to charge late-night alcohol retailers an annual fee (£299-£4440) to manage and police the night-time economy (NTE). RESULTS: When the LNL was being considered, stakeholders from different interest groups advanced diverse opinions about its likely impacts while rarely referencing supporting research evidence. Proponents of the levy argued it could reduce crime and anti-social behaviour by providing additional funds to police and manage the NTE. Critics of the levy hypothesised adverse consequences linked to claims that the intervention would force venues to vary their hours or close, cluster closing times, reduce NTE diversity and undermine public-private partnerships. In the first 2 years, levy-funded patrols developed relationships with the licensed trade and the public. The LNL did not undermine public-private partnerships and while some premises varied their hours, these changes did not undermine the intervention's viability, nor significantly cluster venue closing times, nor obviously damage the area's reputation for having a diverse NTE. CONCLUSIONS: This study applies a framework for process evaluation from a complex systems perspective. The evaluation could be extended to measure alcohol-related outcomes and to consider the interplay between the national and local systems.

Impact of public health team engagement in alcohol licensing on health and crime outcomes in England and Scotland: A comparative timeseries study between 2012 and 2019.

Background: Public health teams (PHTs) in England and Scotland engage to varying degrees in local alcohol licensing systems to try to reduce alcohol-related harms. No previous quantitative evidence is available on the effectiveness of this engagement. We aimed to quantify the effects of PHT engagement in alcohol licensing on selected health and crime outcomes. Methods: 39 PHTs in England (n = 27) and Scotland (n = 12) were recruited (of 40 contacted) for diversity in licensing engagement level and region, with higher activity areas matched to lower activity areas. Each PHT's engagement in licensing for each 6 month period from April 2012 to March 2019 was quantified using a new measure (PHIAL) developed using structured interviews, documentary analyses, and expert consultation. Outcomes examined were ambulance callouts, alcohol-related hospital admissions, alcohol-related and alcohol-specific mortality and violent, sexual and public order offences. Timeseries were analysed using multivariable negative binomial mixed-effects models. Correlations were assessed between each outcome and 18-month average PHIAL score (primary metric), cumulative PHIAL scores and change in PHIAL scores. Additionally, 6-month lagged correlations were also assessed. Findings: There was no clear evidence of any associations between the primary exposure metric and the public health or crime outcomes examined, nor between cumulative PHIAL scores or change in PHIAL score and any outcomes. There were no significant associations in England or Scotland when analysed separately or between outcomes and lagged exposure metrics. Interpretation: There is no clear evidence that allocating PHT resources to engaging in alcohol licensing is associated with downstream reductions in alcohol-related health harms or crimes, in the short term or over a seven year follow-up period. Such engagement likely has benefits in shaping the licensing system to take account of health issues longer term, but as current systems cannot reduce alcohol availability or contain online sales, their potential benefits are somewhat constrained. Funding: The ExILEnS project is funded by the NIHR Public Health Research Programme (project number 15/129/11).

Assessing the impact of selective licencing schemes for private rental housing on mental health and well-being: protocol for a mixed-method natural experiment study in Greater London, UK.

INTRODUCTION: The UK private rental housing market has poorer quality housing compared with other sectors and is subjected to calls for better regulation. Poor quality housing poses risks to mental and physical health, and housing improvement can potentially benefit health and well-being. Local authorities have powers to implement selective licencing (SL) schemes in specific localities. Such schemes involve landlord registration, payment of licence fees, local authority inspection and requirements that landlords conduct any necessary renovation works to ensure housing standards are met. We aim to evaluate SL in Greater London and to test the feasibility of a national evaluation. METHODS AND ANALYSIS: We will measure individual-level and area-level impacts of SL in Greater London between 2011 and 2019. A difference-in-differences approach with propensity score-matched controls will be used. We propose to exploit data from the Annual Population Survey (APS) and health and social benefit registers to measure mental health and well-being at individual (self-reported anxiety) and area (Small Area Mental Health Index) level. We estimate 633 APS participants in our intervention groups compared with 1899 participants in control areas (1:3 ratio of intervention to control). Secondary outcomes will be self-reported well-being and residential stability at the individual level and incidence of police-recorded antisocial behaviour calls and population turnover at the area level. The study size of the area-level analyses will be 3684 lower layer super output areas (including controls). Qualitative semistructured interviews with lead implementers in several London boroughs will produce insights into variations and commonalities between schemes. ETHICS AND DISSEMINATION: Ethical approval was obtained from London School of Hygiene and Tropical Medicine's Ethics Committee (reference number 26481) and London Borough of Hackney. All interviewees will be asked for informed written consent. Study findings will be published in a peer-reviewed journal.

Understanding the Online Environment for the Delivery of Food, Alcohol and Tobacco: An Exploratory Analysis of 'Dark Kitchens' and Rapid Grocery Delivery Services.

Online spaces are increasingly important in the sale of food, alcohol and tobacco. This analysis focuses on two developments in online food delivery: delivery-only 'dark kitchens' and rapid grocery delivery services (RGDS), with the aim to understand and assess the availability of health harming and health promoting products through these services. Data was collected for one metropolitan local authority in London, UK, using publicly available online sources. Being explorative in nature, the analysis includes descriptive statistics and qualitative assessment. Three dark kitchens (renting kitchens to 116 food businesses), three grocery delivery apps, and 76 grocery businesses available through online delivery platforms were identified. Most businesses renting dark kitchen space were 'virtual restaurants' (52%) selling fast food (47%) or dessert (21%) through online delivery platforms. RGDS sold a variety of items, with a focus on pre-packaged foods high in fat, salt and sugar, alcoholic beverages and tobacco. These items were also most likely to be promoted through offers and promotional language. Fruits and vegetables were less commonly available and mainly on grocery delivery apps. Online delivery services increase the temporal and geographic availability and promotion of many unhealthy products. Research expanding on the geographic area of interest is needed.

'It All Kind of Links Really': Young People's Perspectives on the Relationship between Socioeconomic Circumstances and Health.

Meaningful inclusion of young people's perceptions and experiences of inequalities is argued to be critical in the development of pro-equity policies. Our study explored young people's perceptions of what influences their opportunities to be healthy within their local area and their understandings of health inequalities. Three interlinked qualitative focus group discussions, each lasting 90 to 100 min, with the same six groups of young people (n = 42) aged 13-21, were conducted between February and June 2021. Participants were recruited from six youth groups in areas of high deprivation across three geographical locations in England (South Yorkshire, the North East and London). Our study demonstrates that young people understand that health inequalities are generated by social determinants of health, which in turn influence behaviours. They highlight a complex interweaving of pathways between social determinants and health outcomes. However, they do not tend to think in terms of the social determinants and their distribution as resulting from the power and influence of those who create and benefit from health and social inequalities. An informed understanding of the causes of health inequalities, influenced by their own unique generational experiences, is important to help young people contribute to the development of pro-equity policies of the future.

Changes in household food and drink purchases following restrictions on the advertisement of high fat, salt, and sugar products across the Transport for London network: A controlled interrupted time series analysis.

BACKGROUND: Restricting the advertisement of products with high fat, salt, and sugar (HFSS) content has been recommended as a policy tool to improve diet and tackle obesity, but the impact on HFSS purchasing is unknown. This study aimed to evaluate the impact of HFSS advertising restrictions, implemented across the London (UK) transport network in February 2019, on HFSS purchases. METHODS AND FINDINGS: Over 5 million take-home food and drink purchases were recorded by 1,970 households (London [intervention], n = 977; North of England [control], n = 993) randomly selected from the Kantar Fast Moving Consumer Goods panel. The intervention and control samples were similar in household characteristics but had small differences in main food shopper sex, socioeconomic position, and body mass index. Using a controlled interrupted time series design, we estimated average weekly household purchases of energy and nutrients from HFSS products in the post-intervention period (44 weeks) compared to a counterfactual constructed from the control and pre-intervention (36 weeks) series. Energy purchased from HFSS products was 6.7% (1,001.0 kcal, 95% CI 456.0 to 1,546.0) lower among intervention households compared to the counterfactual. Relative reductions in purchases of fat (57.9 g, 95% CI 22.1 to 93.7), saturated fat (26.4 g, 95% CI 12.4 to 40.4), and sugar (80.7 g, 95% CI 41.4 to 120.1) from HFSS products were also observed. Energy from chocolate and confectionery purchases was 19.4% (317.9 kcal, 95% CI 200.0 to 435.8) lower among intervention households than for the counterfactual, with corresponding relative reductions in fat (13.1 g, 95% CI 7.5 to 18.8), saturated fat (8.7 g, 95% CI 5.7 to 11.7), sugar (41.4 g, 95% CI 27.4 to 55.4), and salt (0.2 g, 95% CI 0.1 to 0.2) purchased from chocolate and confectionery. Relative reductions are in the context of secular increases in HFSS purchases in both the intervention and control areas, so the policy was associated with attenuated growth of HFSS purchases rather than absolute reduction in HFSS purchases. Study limitations include the lack of out-of-home purchases in our analyses and not being able to assess the sustainability of observed changes beyond 44 weeks. CONCLUSIONS: This study finds an association between the implementation of restrictions on outdoor HFSS advertising and relative reductions in energy, sugar, and fat purchased from HFSS products. These findings provide support for policies that restrict HFSS advertising as a tool to reduce purchases of HFSS products.
