Many professional organizations and associations hold conventions and conferences on an annual basis. Health Education professional associations take part in this process. Using a historical research perspective, this article delineates conference themes for four prominent professional Health Education associations: the American Association for Health Education (AAHE), the American Public Health Association (APHA), the American School Health Association (ASHA), and the Society for Public Health Education (SOPHE). Data were collected, examined, analyzed by thematic content analysis, and then organized by association, year and location. Development of an appropriate methodology for thematic data collection and analysis are described. (Contains 3 tables.)
