Behavioral medicine is concerned with the integration of knowledge in the biological, behavioral, psychological, and social sciences relevant to health and illness. These sciences include epidemiology, anthropology, sociology, psychology, physiology, pharmacology, nutrition, neuroanatomy, endocrinology, and immunology. The term is often used interchangeably, but incorrectly, with health psychology.. The practice of behavioral medicine encompasses health psychology, but also includes applied psychophysiological therapies such as biofeedback, hypnosis, and bio-behavioral therapy of physical disorders, aspects of occupational therapy, rehabilitation medicine, and physiatry, as well as preventive medicine. In contrast, health psychology represents a stronger emphasis specifically on psychology's role in both behavioral medicine and behavioral health.
　　行为医学是研究与健康和疾病相关的生物、行为、心理和社会科学知识的整合。这些科学包括流行病学、人类学、社会学、心理学、生理学、药理学、营养学、神经解剖学、内分泌学和免疫学。这一术语经常与健康心理学互换使用，但不正确。。行为医学的实践包括健康心理学，但也包括应用的心理生理疗法，如生物反馈、催眠、物理障碍的生物行为疗法、作业疗法、康复医学、物理疗法以及预防医学。相比之下，健康心理学更强调心理学在行为医学和行为健康中的作用。
