Application of Artificial Intelligence (AI) in Health Promotion: A Case Study of an Experience From a Public Health Institution in Sri Lanka.

This case study explores the application of artificial intelligence (AI)-based technologies by the Health Promotion Bureau, one of the main preventive health institutions in Sri Lanka. Public engagement was analyzed via randomly selected posts created via AI-based and non-AI-based technologies on the basis of their reach and engagement. The use of AI-generated images for health communication on social media platforms markedly enhanced public engagement, with AI posts achieving 30%-40% greater reach and interaction than non-AI posts. AI technologies facilitate effective advocacy, mediation, and enabling strategies; support policy reforms; improve stakeholder collaboration; and empower communities. In addition to these successes, the institution has faced several challenges regarding data governance, infrastructure, workforce skills, and strategic partnerships. This study highlights the requirements for formal data governance mechanisms, advanced analytical infrastructure, and structured training programs to maximize the benefits of AI-based technology. These findings suggest that public health institutions are better at integrating AI technologies to improve health promotion efforts, and further research is needed to evaluate public engagement with AI-developed materials.
