Abstract Background Promoting health rather than treating disease is gaining popularity and promotion initiatives are increasingly situated in the societal domain. In this scoping review, the literature on quantitative health impact assessment (HIA) practice and methodology is explored in order to provide an overview of methods that have been used or proposed for estimating societal initiatives’ health outcomes. Methods Systematic searches were done in PubMed and Web of Science in order to identify relevant literature. A set of selection criteria ensured that studies held useful quantitative HIA methodology and a societal approach. Reference lists of all selected studies were then examined for other studies. After literature selection, quantifiable features of interest were recorded and general observations on the composition of the current literature were made. Results The literature selection process yielded 54 included studies, most of which focus on lifestyle-related determinants. Of different health outcome measurements, deaths (averted) was most frequently used, followed by life years and quality- and disability-adjusted life years. Equity is frequently mentioned, but not often estimated. Most studies made estimates based on simulation models, notably with Monte Carlo, Markov and system dynamics models (simulation period mean 46 years; median 50 years). Inputs for the models such as relative risks, transition probabilities and price elasticities were taken from census and register data, survey data, evidence from previous (scientific) studies and outcomes from stakeholder sessions. Conclusions HIA holds a wide range of practices with some overlap. Different methods’ strengths and weaknesses partly depend on the phenomenon of interest. Some policy types have standard approaches, but there is no one universal optimal method and therefore having a grasp of multiple methods is useful. Furthermore, estimating health effect distributions could make an important addition to HIA. Key messages Quantitative HIA can be conducted using various methodological bases and most studies use some form of simulation modelling. Different simulation methods are distinct, but do show some overlap. Quantitative HIA topics often relate to individual behaviour (micro-level proximal determinants). There is room for HIA method development for determinants with indirect connections to the individual.

Abstract On March 29th 2019, the United Kingdom (UK) was due to exit the EU in a process known informally as ’Brexit’. This exit and entry into a 2-year transition is a period of unprecedented political and social upheaval - with many unknowns and much uncertainty attached to the outcomes and future impact. In preparation for Brexit, Public Health Wales commissioned the Wales HIA Support Unit to carry out a health impact assessment of Brexit in Wales to support and inform its and other public bodies planning and future work. This paper examines the unique HIA carried out between July and December 2018 on the impact of the UK withdrawal from the EU in Wales. It discusses the robust, participatory process undertaken, the stakeholders involved and the benefits reaped from this. It highlights the evidence gathered and analysed including the collection methods, the complex nature of the work and disseminates the main findings from the HIA including the potential determinants of health and population groups identified. Finally, it describes the challenges faced, how these were overcome, and the huge benefits, impact and influence it has had to date across a wide range of UK and Welsh organisations and public bodies. This work demonstrates continued leadership in the field of impact assessment and spearheads the requirement for public bodies to carry out HIAs as part of the forthcoming statutory requirements of the Public Health (Wales) Act 2017 an can inform practice at a global level. Key messages HIA can inform and influence action in response to important strategic decisions. The Brexit HIA is a unique example which can inform international HIA practice.

Objective. To explore how three different assumptions on demographics affect the health impact of Danish emitted air pollution in Denmark from 2005 to 2030, with health impact modeled from 2005 to 2050.Methods. Modeled air pollution from Danish sources was used as exposure in a newly developed health impact assessment model, which models four major diseases and mortality causes in addition to all-cause mortality. The modeling was at the municipal level, which divides the approximately 5.5 M residents in Denmark into 99 municipalities. Three sets of demographic assumptions were used: (1) a static year 2005 population, (2) morbidity and mortality fixed at the year 2005 level, or (3) an expected development.Results. The health impact of air pollution was estimated at 672,000, 290,000, and 280,000 lost life years depending on demographic assumptions and the corresponding social costs at 430.4 M€, 317.5 M€, and 261.6 M€ through the modeled years 2005–2050.Conclusion. The modeled health impact of air pollution differed widely with the demographic assumptions, and thus demographics and assumptions on demographics played a key role in making health impact assessments on air pollution.

Health impact assessment (HIA) is a systematic and flexible tool, which is advocated by the World Health Organisation as a method through which to consider the impact of policies on the health and well-being of a population, and the inequalities that may arise because of it. In 2018, the HIA support unit in Wales carried out a comprehensive and unique HIA on the impact of Brexit in Wales. The aims were to understand the differential impacts that Brexit would have on the health and well-being of the population and to provide evidence to inform decision makers across a range of public bodies. It followed a five-step process for HIA and utilised a wide range of evidence sources and health intelligence including both quantitative and qualitative evidence. This paper reflects on the process of carrying out the HIA and the methods used. It discusses the stages of the HIA, and shares the findings and reflections of implementation which will be beneficial to other HIA practitioners and policy makers. It does not concentrate on the findings of the HIA in detail, but focusses on what worked and any challenges encountered. It has been used to progress the practice of HIA in Wales and demonstrates the value of HIA as a method to inform and influence complex decisions.

Abstract Humans worldwide are exposed to a wide range of chemicals through their diets, consumer products and the environment, often changing in concentrations, combinations and over time. Health impact assessment (HIA) for exposure to chemicals is poorly defined and its contribution to the global burden of disease is difficult to quantify and certainly underestimated. The importance of taking actions for reducing deaths and illness associated to hazardous chemicals is reflected in the UN Sustainable Development Goals target 3.9, as well as in the 7th European Environment Action Programme or in the European Green Deal (Communication of the European Commission, COM (2019) 640 final). Recent discussions suggest that current EU Legislation, while contributing to reducing the overall risks of chemicals in the environment, is protecting mainly against highly toxic chemicals in the workplace. However, the assessment of potential health impacts over the general population is limited by uncertainties related to data collection, health indicators and confounding factors. Concerns have also been reported regarding the increased introduction in the market and the environment of new substances with unknown properties as well as referring to the chronic, low-level exposure to chemical mixtures, which are considered to be poorly characterised and yet to be systematically addressed. Notably, in recent years the European Commission (EC), acknowledging that the assessment and management of mixtures is only partly covered by current legislation, has identified several gaps and areas for action. With regard to carcinogens, the proportion of non-genotoxic carcinogens in the environment is expected to increase, since industrial chemists are designing compounds without overly reactive moieties. In addition, the manufacture and use of novel types of substances including nanomaterials, new generation pesticides and pharmaceuticals (e.g. biologicals, cell and gene therapies) are expected to increase. This raises new challenges for the assessment and risk management of the carcinogenicity impacts of chemicals. The present workshop intends to provide an overview of the different initiatives conducted in Europe at different scales (European, national and regional), to address such defies related to the HIA of chemicals. Specifically, we will debate about existing data sets for characterising both human exposure and health effects related to chemicals, new approaches and guidance for the assessment of exposure to mixtures, and the carcinogenicity impacts as well as how all that is being translated to policy actions. Key messages Increasing global trend of human exposure to chemicals demands holistic approach for action. Several research/policy initiatives for improving HIA-chemicals are ongoing, with expected strong impacts.

Abstract Most scientific communities and governments accept that a global warming process is occurring, and are concerned about its alarming potential environmental and health consequences. The extreme conditions associated to climate change such as severe storms, floods and prolonged heatwaves and droughts, are expected to increase considerably the burden of climate-sensitive diseases (e.g. heat-related illness, new and emerging infectious diseases, respiratory diseases or threats to food security). Poor countries are most at risk, but developed economies can also be strongly affected as illustrated by the large number of deaths associated to the European heat wave of 2003. Conducting health impact assessment of climate change (HIA-CCh) requires the analyses of complex interactions between humans and natural ecosystems, demanding an interdisciplinary approach and a wide range of tools and techniques. Those analyses should be simultaneously context specific and extend over time to track not only the full dimension of health impacts but also the efforts needed to adapt and build resilience. Standard indicators for climate-sensitive health outcomes alone will not adequately capture the changing risks typically related to climate change. In addition to them, indicators of vulnerability and exposure, adaptation planning and resilience for health, and learning and knowledge management are required. The present workshop aims at analysing and sharing expertise on how to conduct an HIA-CCh, with the following elements for discussion: Definition of the scope (both temporal and spatial) and the interdisciplinary team to be involved in the processSelection of indicators that will allow not only characterization of health impacts but also promoting and tracking adaptation activities at national and local health departmentsForesight climate change scenarios and how this can be incorporated into the decision-making processVulnerability risk in relation to impact assessment and health / health equity in the context of climate changeHow the proper HIA-CCh can have an impact on learning and changes in management frameworks Key messages Increasing public health’s adaptive capacity to face climate-sensitive threats is needed. Conducting HIA-CCh requires innovative management strategies and proper selection of indicators.
