Healthcare systems around the world are struggling to deliver accessible and affordable care amid increased demand from a growing middle class, aging populations and changes in our natural environment. Obesity, cardiovascular disease, diabetes and other chronic conditions are no longer problems for developed regions of the world only – they now account for 83 percent of mortalities in developing nations as well.

Changing our habits is usually hard, even the ones that might benefit us. While people know better and generally aspire to be healthy, we still have trouble changing unhealthy behaviors. What can business and community leaders do to make individual behavior change easier? How can our healthcare systems evolve so that they remain sustainable for the long-term? Where do we start?

The summit convenes the world's most influential leaders, thinkers and practitioners to advance innovation toward action and scale.
