Determinants of evidence use in public health policy making: Results from a study across six EU countries

•Media attitude towards underpinning policy with evidence influences policy decision makers.•Individual skills, attitudes, values of policy makers impact the extent evidence use.•A solid research infrastructure is facilitating but not sufficient for evidence use.•Factors that impact evidence use in policy making differ by country and policy context.•Interventions connecting policy makers and researchers in the policy context seem most promising.

The knowledge-practice gap in public health is widely known. The importance of using different types of evidence for the development of effective health promotion has also been emphasized.Nevertheless, in practice, intervention decisions are often based on perceived short-term opportunities, lacking the most effective approaches, thus limiting the impact of health promotion strategies. This article focuses on facilitators and barriers in the use of evidence in developing health enhancing physical activity policies.Data was collected in 2012 by interviewing 86 key stakeholders from six EU countries (FI, DK, UK, NL, IT, RO) using a common topic guide. Content analysis and concept mapping was used to construct a map of facilitators and barriers.Barriers and facilitators experienced by most stakeholders and policy context in each country are analysed. A lack of locally useful and concrete evidence, evidence on costs, and a lack of joint understanding were specific hindrances. Also users' characteristics and the role media play were identified as factors of influence.Attention for individual and social factors within the policy context might provide the key to enhance more sustainable evidence use. Developing and evaluating tailored approaches impacting on networking, personal relationships, collaboration and evidence coproduction is recommended.
