This chapter discusses definitions of health and health promotion. It defines episodic health as seeking treatment during illness, while preventive medicine focuses on lowering risk factors. Individual health promotion focuses on risk reduction, while community health promotion emphasizes group empowerment. The goals of Healthy People 2010 are to increase quality life and eliminate health disparities. Behavior change is difficult due to various influencing factors, but can be achieved through the stages of change model involving pre-contemplation to termination. Today's college students are traditionally young adults but also include non-traditional older students and growing minority populations. A new definition of health focuses on the role of health as a process and the intrinsic and extrinsic resources that compose health.
