Podcasts as a tool for promoting health-related behaviours: A scoping review

Podcasts are a popular medium for delivering health-related content, potentially influencing physical and mental health behaviours and outcomes. This scoping review evaluates the impact of health podcasts on such outcomes, engagement levels, and public perceptions.

This scoping review followed the Arksey and O'Malley framework and PRISMA-ScR guidelines. Qualitative or quantitative articles published from 2004 onward were included. Eligibility criteria were developed using the Population, Exposure and Outcome framework. Included articles examined the use, engagement with, or perspectives towards health-related podcasts. Data were synthesised narratively.

Fifty articles encompassing 38 studies were analysed. Significant improvements (p < 0.05) were observed in health monitoring, knowledge, behaviours, attitudes, chronic disease management, maternal health and behavioural improvements. Results were mixed for physical activity (n = 2 significantly improved, n = 2 no change), fruit and vegetable consumption (n = 1 significantly improved, n = 1 no change), and weight outcomes (n = 2 significantly improved, n = 2 no change). No significant changes were observed in depression and anxiety. Podcast engagement studies (n = 7) reported participation rates between 62% and 83% and an average weekly listening duration of 103-124 minutes. There was high satisfaction, trust and appreciation for podcasts that effectively blended personal anecdotes with reliable medical information. Sample sizes ranged from 7 to 722, with sample age ranging from under 18 to 73.2 ± 6.2 years. Studies included both male (n = 1), female (n = 6) and mixed samples (n = 24). Podcasts were used individually (n = 19), alongside other supportive technology such as apps and online material (n = 11) and retrospective podcast use was analysed in cross-sectional (n = 3) and a single (n = 1) audit. Duration of podcasts ranged from 30 seconds to 24 minutes.

Podcasts show promise as effective tools for health promotion, achieving strong engagement and effects on knowledge and behaviours. Future research should explore content innovation and integration into health interventions, and long-term effectiveness.
