Objective: Schools are important settings for health promotion. In schools, children and adolescents can be reached regardless of their social background, which represents a unique opportunity for promoting health. Several studies have demonstrated the importance of school leadership in initiating and sustaining health promotion; however, efforts to systematically review the influence of school leadership on school health promotion are still lacking. Hence, this paper analyses empirical studies published in scientific journals on school leadership and health promotion in schools. Design: Systematic literature review. Method: Informed by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, a review was conducted using two main databases: Web of Science and Scopus, which retrieved 51 eligible articles. Results: The review of these articles resulted in the identification of seven main themes -- school leaders' health; attitudes, knowledge and behaviour; accountability; support from school leaders; shared leadership approaches; capacity building and parent engagement. Conclusion: This systematic literature review expands the literature by highlighting the school leadership factors that promote school health promotion in Oceania, Europe, North America, South America, Africa and Asia continents. Future systematic literature reviews could explore studies and different aspects of health promotion by teachers, especially in the Asian context.
