Abstract
(1) In the field of health promotion, municipalities offer opportunities to reduce SES-based health inequalities by addressing vulnerable communities. This research project aims to identify facilitating and inhibiting factors for the creation of healthy living environments. (2) After preliminary literature and qualitative research work, an online-based Delphi survey was conducted (December 2020-March 2021). This included the rating and commentating of 22 theses at two times, whereby the results of the first round of rating were visible to the participants the second time. (3) Twelve experts from seven European countries participated in the Delphi survey across both rounds (1st round: n = 37; 12 countries). The consensus was particularly clear with regard to providing resources, which, in turn, are especially necessary for involving target groups in health promotion. (4) The results illustrate the relevance of further cross-national exchange. Certain aspects however, such as the HiAP approach or strategies to reach disadvantaged groups, are still challenging in practice. In order to develop concrete recommendations, the theses need to be further operationalised. The Delphi method offers a suitable possibility to map international expertise in this field and with a focus on health equity.
