[Evidence-based primary prevention and health promotion: methods and procedures in 5 research consortia]

Between 2014 and 2022, the 5 German research networks AEQUIPA, CAPITAL4HEALTH, HLCA, PartKommPlus, and SMARTACT are investigating topics of primary prevention and health promotion with the aim of further deepening the evidence base in these areas. The work of the 5 research networks for primary prevention and health promotion is presented, analysed, and discussed from an internal perspective. A model of evidence-based public health serves as a structuring framework.The 5 research networks use a variety of access routes for the generation of evidence with regard to the participation of nonacademic, civil society actors and users. There is a wide range of study designs - from randomised controlled trials and systematic reviews to diverse qualitative designs. The use of models and theories supports the evidence base. Beyond evidence generation, all research networks focus on at least exemplary implementation of new evidence.Due to the diversity of methods, a diversified evidence-based approach can be realised, taking into account network-specific aspects. Structural circumstances limit the further systematic strengthening of the evidence base. In particular, the involvement of nonacademic, civil society actors for the work with hard-to-reach target groups often cannot be financed or is considered too time consuming under the given circumstances. The COVID-19 pandemic highlights the importance of a flexible spectrum of methods, employing both digital and analogue methods in a meaningful way.
