Chess, not chequers: the need for a complex systems approach to public health

The prevalence of chronic diseases is increasing, inequalities are widening, and the resources to respond are ever more constrained.
There are no simple answers to any of this, but an important part of the problem may lie in the ways in which we conceptualise these challenges, grounded in traditional models of cause and effect. Reconceptualising these challenges in ways that truly take account of their complexity allows us to generate more relevant kinds of evidence, construct more meaningful practical and policy responses, and evaluate those responses in more appropriate ways. This talk will explore these themes, and propose ways in which they might be achieved.
