    The ENHIS methodology

    ENHIS indicators aim at reflecting and communicating the status of environment and health issues in Europe. They are tools to monitor health and environment trends in countries, to evaluate the effectiveness of relevant policies and to make comparisons of countries’ progress towards the targets set in Europe-wide action programmes.

    ENHIS developed a methodology for a set of indicators to measure and report on health and its relation to environmental risk factors, focusing on children’s health. Topic areas were defined based on the information needs of current policies, in particular the Children’s Environment and Health Action Plan for Europe (CEHAPE). A number of indicators were identified using the state-of-art scientific evidence about environment-related health impacts. The focus was on environmental factors most relevant to health, on health outcomes most influenced by the environment, and on policy actions deemed to reduce and prevent the risks. Twenty-six ‘core’ indicators were selected. Twelve of them are applicable to the general population.

    ENHIS methodological guidelines were developed for thirty indicators giving the rationale, definition, required data elements, calculation method, data sources, interpretation and policy relevance. To ensure that the information collected on the indicators was consistent and user-friendly, a template for a methodology sheet was designed to include the rationale and definition of the indicator, underlying concepts and definitions, specification of the data needed, data sources, availability and quality, method of computing the indicator, scale of application, interpretation of the result, linkage with other indicators, details of any related data and websites, policy and regulatory context of the indicator and any relevant reporting obligations.

    A real life application of the methodology for environmental health indicators was achieved by developing methods and guidelines for information generation based on existing data. A methodological guidance for generation of environmental health indicators from international databases and recognized surveys was developed to enhance effective use and re-use of readily available data.

    The DPSEEA framework

    A framework represents a simplified version of our underlying concept of reality and makes this view of the world explicit to the audience. It also helps to be more systematic in defining the issues that confront us and in analysing and interpreting them. Embedding indicators for children’s health and the environment within an appropriate framework has several advantages.

    The DPSEEA framework for environmental health indicators, developed by the World Health Organization (WHO, Environmental Health Indicators and Methodologies, 1999), was a key starting point for ENHIS because it reflects the link between exposures and health effects as determined by many different factors operating through a chain of events, and clearly shows the many entry points for interventions. The DPSEEA model describes the cause-to-effect chain through Driving Forces, Pressures, State, Exposure, Effects and Actions, and provides a framework for analysing interrelated factors that impact on human health. The ENHIS indicators focus on the linkages between the Exposure, Effects and Actions parts of the chain. In case of lack of information, proxies of exposures from upstream environmental determinants were used.

    As a drawback, the DPSEEA framework stresses the linear links between environment and health, therefore is not able to fully represent the complexity of the many-to-many associations between exposures and health outcomes.


    Global Initiative on Children’s Environmental Health Indicators

    The development of environmental health indicators to monitor the trends in the health status of European children contributes towards the objectives of the Global Initiative on Children’s Environmental Health Indicators (CEHI) that was launched at the World Summit on Sustainable Development (WSSD) in 2002.

    A number of projects or institutions work with environmental health indicators, including:
