This booklet addresses the growing importance of health in adult learning and the interest in joint action. Section 1 describes the context, one in which substantial, but unevenly spread, progress has been made in improving global health. Section 2 examines the social aspects of health and explains how what is defined as health or sickness depends not only on individuals and biological factors but on the social and cultural environment within which individuals live, work, and interact. Section 3 defines health promotion, which builds on a social and cultural understanding of health and illness, as the process of enabling people to increase control over their health through advocacy and intersectoral action; health education as a component of health promotion; and community action as a key component of health promotion policies. Section 4 discusses the closeness between health education and adult learning as reflected in the similarity of goals and principles that characterize both contemporary adult education and health promotion policies. Section 5 focuses on health as a basic human right. Section 6 defines health literacy. Section 7 describes projects in Nepal, Germany, and Bolivia that illustrate the links between health and adult education. Section 8 outlines policies and aims that adult education programs for health promotion should include. (YLB)
