RESUMO
OBJECTIVE: We aimed to assess evidence of the effectiveness of song-based public health programmes and to examine the analyses of song lyrics to learn what their key qualities for public health promotion are. METHODS: A systematic search was employed to identify empirical studies that examined song interventions for public health education and promotion. We searched the following databases: MEDLINE, PubMed, CINAHL, PsycINFO and AMED. We also backwards searched references of all relevant studies. RESULTS: Of the 137 studies identified, ten studies were included: four were quantitative and six were qualitative. The qualities of the included studies were assessed to be fair or good. The studies were from developing/low-income countries, South Africa and the United States, involving children and adults. Through a narrative data synthesis, three themes were identified; song-based programmes increased public health knowledge and changed behaviours. Additionally, developing songs for public health promotion involved consultations with local people utilising culturally and socially relevant genres or songs. CONCLUSION: Although the current evidence is limited by the small number of available studies and their heterogeneity, there is evidence that songs may be an effective method to deliver public health messages that result in improved education and changes in behaviour. Several advantages of using songs as public health strategies were identified that included their social and cultural relevance, ubiquity, low cost and enjoyment. Given these advantages, further research with the robust methodology is required to assess the benefits of songs using quantifiable outcomes along with evaluation of processes. We recommend that public health professionals, stakeholders and communities utilise songs as public health strategies.
