Changes in the activities, functions, and roles of public health educators.

Accounts of early activities of public health educators, statements of the American Public Health Association on the qualifications and functions of these educators, and studies concerned with their responsbiliities, functions, work, or roles are reviewed. These point up the three major foci in public health education over time in the U.S., viz, dissemination of information, community organization, and health behavior and program planning. Functions of public health educators in emerging settings for practice are presented and the implications of this movement (i.e., movement of health educators into non-traditional settings) for public health education profession are discussed.
