This Encyclopedia was designed with the overarching goal to collect together in a single resource the knowledge generated by this interdisciplinary field, highlighting the links between science and practice. In it, scholars, health care practitioners and the general public will find a wealth of information on topics such as physical activity, stress and health, smoking, pain management, social support and health, cardiovascular health, health promotion, and HIV/AIDS. This two-volume set includes more than 200 entries on topics covering all aspects of health and behavior. In addition, the Encyclopedia of Health and Behavior includes a comprehensive set of additional resources with entries on selected organizations and an appendix with a detailed annotated listing of such organizations as well as Web sites of interest.
