Effectiveness of Social Marketing Interventions in Health Promotion: A Narrative Review with Implications for Low- and Middle-Income Countries

Background
Public health challenges are becoming increasingly complex, and there is a growing need for approaches that extend beyond traditional health education. Social marketing has gained attention as a practical framework that applies marketing principles to encourage voluntary behaviour change and improve population health, particularly in low- and middle-income settings.
Methods
This study adopted a narrative review approach to synthesise evidence from peer-reviewed studies, theoretical perspectives, and global health reports. Sources were selected based on their relevance and contribution to understanding how social marketing is applied in health promotion practice.
Results
The findings indicate that social marketing interventions can positively influence health-related behaviour, particularly when they are guided by behavioural theory and informed by a strong understanding of the target population. Evidence from Ghana highlights the value of community-based approaches that combine service delivery with behaviour change strategies.
Conclusion
Overall, social marketing offers a flexible and practical approach to health promotion. Its impact is greatest when interventions are tailored to local contexts, guided by theory, and supported by effective policies and community engagement.
