Abstract
Rationale Intersectoral action (ISA) has been at the forefront of public health policy
discussions since the 1970s. ISA incorporates a broader perspective of public health issues
and coordinates efforts to address the social, political, economic and environmental contexts
from which health determinants operate and are created. Despite being forwarded as
a useful way to address and treat complex or ‘wicked’ problems, such policy issues are still
often addressed within, rather than across, disciplinary silos and ISA has been documented
to fail more often than it succeeds.
