Do we really know what works best when it comes to health promotion? And when we learn what works, are we making sure others know, also? These are some of the questions we explore in this podcast with Michel O'Donnell, PhD, editor of the American Journal of Health Promotion. O'Donnel is also program chair of a March 15 conference on "The Art and Science of Health Promotion," where noted experts will also be addressing these questions.
