The present master thesis deals with the need and the possibilities of health-promoting social work in old age. Health promotion operates on the behavioral and the relationship level. Therefore, in this study, information has been gathered about the factors that influence the health behavior of the elderly and their demands on social work. It has also been clarified how experts in the field of health promotion perceive the target group of elderly persons and how they are promoting the health of these. A total amount of four interviews with older people and three interviews with experts have been accomplished, all of them partially structured. It is found that elderly people are largely satisfied with their health behavior and hardly place demands on social work. Experts, however, see a clear need for intervention. Possible working methods for social work are e.g. in the field of knowledge transfer and in the early detection of problems and early intervention by visiting people at their homes. All offers of social work should be barrier-free and easily accessible, taking into account the autonomy and self-determination of the elderly.
