The societal role which sports clubs can play in promoting health has been underexploited, and sports clubs have called for support from policymakers. Based on the Health Promoting Sports Clubs National Audit Tool, the present study has as objective to investigate how national public policies support health promotion in sports clubs, by questioning indicators of quality (references to other document, policy framing and evaluation), the content (target groups, health topics, type of policy instruments) and the mechanisms used by Irish decision-makers for coordination, evaluation, dissemination and implementation of these policies. The tool was completed in two steps comprising a systematic search of policy plans, programmes or regulations and 12 interviews with key informants. A content analysis of 17 policy documents, identified 49 policy actions targeting HP in sport clubs, coming from different sectors, but only policies from the health sector considered a settings-based approach, supporting a unique sports federation programme. Policies focus on a single health behaviour, where the most targeted were physical activity participation, gender inequity and the disability gap in access to sport clubs. The policy structure lacks coordination, monitoring, media campaigns and events, and therefore not adopting the HPSC concept, but only a health education approach. Future studies should support the acknowledgement of HP as an umbrella concept, in order to support the understanding and development of organisation and system change since policies are drivers for sport federations, local sport actors and sports clubs.
