There are many arenas within which health promotion may be located. This paper addresses the issues involved in the development of health promotion in one such arena: the community health movement. This movement is complex and dynamic. When reference is made to non-statutory health action, or to community involvement in health, this complexity may not be fully appreciated. There is a tendency for the range of activity to be reduced to its most “visible” form: self-help activity. However, there is more to the community health movement than this. A typology is offered here in which three levels of community-based activity in Britain are identified. These are referred to as self-help groups, community health groups and community development health projects. The breadth and range of this activity reflects the inability of formalized health care to tackle many of the underlying causes of ill-health. Each type of community health activity exists as a declaration of this failure, but some forms of activity may be welcomed by the health professions whilst others may not. In particular the numerically small community development health projects offer a significant challenge to formal health care because they seek to encourage collective health activity by those who are least in control of their own health. It is within the context of developing strategies for health promotion that community health action is most relevant. National and local strategy documents suggest that community involvement is essential for the successful promotion of health. Fully comprehensive participation by community groups signifies a major shift in our perceptions of health and health care. An appreciation of the existing range of health action in communities is an important starting point for medical health professionals engaged in this task.
