The interface of multisectoral and multilateral dimensions of public health policy: what's new in the 21st century?

The article examines key developments unfolding in the 21st century in the intersection of multisectoral and multilateral dimensions of public health policy. Several processes and mechanisms, relatively new or rapidly evolving, are fuelling this dynamic interface. They include, in particular, expansion of the spectrum of sectors involved in the health domain, the upsurge of trans-border and commercial determinants of health, growing presence of health issues in multilateral instruments and processes that are outside of the health sector, and strengthening the legal base of intersectoral relations and responsibilities for health. They also encompass and reflect important transformations in health diplomacy and governance for health, some of the fundamentals of contemporary public and global health. The article argues that overall, multisectoral and multilateral dimensions tend to interact, inform and reinforce each other, and that such interaction would be one of important drivers of 21st century intersectoral policy-and international cooperation-for health.
