Health Promotion and Health Education: Theories, Models and Methods

Background: Health education and promotion have evolved to address complex health challenges by integrating epidemiology, behavioural, and social sciences. Despite their theoretical foundations, gaps persist between theories and real-world applications due to poor adaptation and implementation strategies. Methods: This narrative review analysed peer-reviewed articles, books, and reports from PubMed, Google Scholar, WHO, and CDC publications. Search terms included health education, health promotion, health communication, and behaviour change theories. Result: Effective health promotion relies on theory-guided approaches operating at different levels. At the individual Level, models such as the Health Belief Model, Theory of Planned Behaviour, and Transtheoretical Model help to understand perceptions, intentions, and motivation for healthy behaviours. Interpersonal Level theories like Social Cognitive Theory emphasise the role of social influences and observational learning through networks. At the community level, Community Organisation Theory and Diffusion of Innovations highlight collective action and the spread of new ideas. Broader frameworks, including the Ecological and PRECEDE-PROCEED Models, are designed to address comprehensive determinants at multiple levels and emphasise planning, implementation and evaluation. Health promotion techniques and methods operationalise these theories and highlight a shift from individual-focused strategies to approaches that challenge systemic barriers and social norms for lasting behaviour change. Conclusion: While health education and promotion effectively improve public health and reduce inequalities, significant challenges remain, particularly in low- and middle-income countries facing resource constraints, weak health systems, and policy gaps. Success requires bridging research and practice through culturally relevant, adequately funded, and policy-supported interventions to achieve a sustainable public health impact.
