Need for Innovation in Public Health Research.

The recent conference Turning the Tide: A New Generation of Public Health Interventions highlighted the need to utilize innovative and emergent methodologies to confront increasingly complex public health challenges. In this commentary, we discuss three dominant themes from the conference: addressing multiple levels of causality in reducing health problems; technology-based methodologies to enhance health promotion; and improving translation and sustainment of effective health promotion programs. The subsequent articles, included in this supplement issue of AJPH, provide compelling examples and arguments supporting these progressive approaches to public health promotion. We recommend that public health researchers draw inspiration from these examples and embrace interdisciplinary, innovative methods within their future work.
