The Effects of Arts-Based Interventions in the Treatment and Management of Non-Communicable Diseases: An Umbrella Review and Meta-Analyses
This umbrella review and meta-analysis of 149 systematic reviews demonstrates that arts-based interventions, particularly music and dance, provide significant medium-to-small benefits for physical, psychological, cognitive, and quality-of-life outcomes in patients with non-communicable diseases such as cancer, cardiovascular disease, and mental health conditions, suggesting they are a valuable addition to standard medical treatments.

In the modern world, a vast majority of deaths are caused not by sudden infections, but by long-term conditions that develop slowly over time. These non-communicable diseases, a category that includes heart disease, cancer, diabetes, chronic lung issues, and neurological disorders like dementia, require ongoing management rather than a quick cure. While medicine provides essential treatments to control these conditions, doctors and health organizations are increasingly looking for ways to support the whole person, not just the disease. This has led to a growing interest in the arts—music, dance, visual art, drama, and writing—as tools for healing. The question is not whether these activities are enjoyable, but whether they can be measured as effective medical treatments that improve physical health, mental well-being, and the overall quality of life for people living with serious, long-term illnesses.
A massive new analysis brings together decades of research to answer this question with a high degree of clarity. Researchers gathered data from 149 separate, high-quality reviews that had already examined hundreds of clinical trials. Instead of looking at individual patients, they looked at the collective findings of these studies to see if arts-based interventions consistently help people with non-communicable diseases. The team distinguished between two types of artistic engagement. One type involves activities led by a trained creative arts therapist, who uses the art form within a professional relationship to achieve specific therapeutic goals. The other type includes arts activities with a stated therapeutic intent, such as a community choir or a dance class led by an instructor, designed to promote health but not necessarily delivered by a clinical therapist. By combining the results of studies covering cancer, heart disease, lung disease, diabetes, mental health conditions, and neurological disorders, the researchers could see the big picture of how these interventions work across different populations.
The findings reveal that engaging with the arts offers meaningful benefits for people with several of these major health challenges. For those living with cancer, heart disease, and mental health conditions, the analysis found a moderate, consistent improvement in their overall health outcomes. This means that, on average, patients who participated in arts-based programs saw noticeable gains compared to those who received standard medical care alone. These gains were particularly strong for psychological well-being, such as reducing feelings of anxiety and depression, and for improving the overall quality of life. In the realm of heart disease, the benefits extended to physical rehabilitation, helping patients recover motor skills and physical function. For people with neurological conditions, such as Parkinson's disease or dementia, the arts provided small but steady improvements in physical movement and cognitive function. The research suggests that these benefits are not limited to a single type of art; while music and dance were the most frequently studied, visual arts and drama also showed positive results, particularly for physical and psychological outcomes.
However, the story is not the same for every disease. The evidence for arts-based interventions in managing chronic respiratory diseases and diabetes remains unclear. In these areas, the available studies were too few or too varied to draw a firm conclusion about effectiveness. The researchers noted that the data for these conditions was imprecise, meaning that while there might be benefits, the current scientific record is not yet strong enough to say for sure. Furthermore, the analysis highlighted a significant gap in global research. The vast majority of the studies included in this review were conducted in wealthy nations, with very little data coming from low-income countries. This leaves a large question mark over whether the results apply equally to people living in different economic and cultural contexts around the world.
The study also looked closely at who delivers the art and how it is delivered. A common assumption might be that a treatment led by a highly trained therapist would always be superior to a community-led activity. Yet, this large-scale review found no major difference in the effectiveness of the two approaches. Whether the facilitator was a credentialed therapist or a community instructor, the positive outcomes for patients were similar. This suggests that the act of engaging in the creative process itself holds significant healing power, regardless of the specific professional title of the person leading the session. The researchers also found that the benefits appeared to be similar for people with a formal medical diagnosis and those who simply reported having significant health complaints, suggesting these interventions could be useful for a broad range of individuals, not just those with a specific label.
Despite the promising results, the researchers urge caution in how these findings are applied. Much of the evidence comes from studies that focused heavily on music and dance, meaning the conclusions are most reliable for those specific modalities. There is also a need for more rigorous studies that clearly separate the different types of interventions and measure long-term effects. The authors emphasize that while arts-based approaches are not a replacement for standard medical treatment, they represent a valuable, low-cost addition to the healthcare toolkit. They offer a way to address physical, emotional, and social needs simultaneously, providing a holistic layer of care that complements traditional medicine. As the global burden of long-term diseases continues to rise, these findings suggest that integrating the arts into treatment plans could be a practical and effective step toward improving the lives of millions of people.
