Along with the longer life expectancy, how can we help elderly to have a healthy and quality life? It becomes an important issue for the researchers and practitioners in the field of gerontology as well as a key project for developing public health and social welfare policies. Moreover, in the existing policy of integrating public health and social welfare, how can we fulfill the goal of “live long and live well” in the levels of individual, community, and policy? Besides to follow the world trend, a key point is to merge the concepts of “health promotion” and “quality care” into the current service program for the elderly. Built from the rationale and background, the author discussed the following topics based on literature and clinical experiences: (1) aging population, disease patterns in elderly, and reactions to the policy, (2) social work in health promotion and public health, (3) health- promotion-oriented service program for the elderly. I hope the current article can help to draw attention on these issues in the field of health and social welfare policy and further discuss research and practice.
