Abstract:Background: Anorexia nervosa is the mental illness with the highest mor-tality rate. Thus, early detection is an important factor for both the progno-sis and the therapeutic cure of this disease. This results in a need to, first, sensitize the entire population especially teachers with regard to ano-rexia and, second, to identify possible methods of prevention and interven-tion.The aim of this thesis is to improve the general understanding for people who suffer from anorexia so that their motives become more comprehen-sible. Moreover, the possibilities and difficulties of a positive therapy will be presented.Therefore, the following issues are addressed: “To what extent did the ratio of affected female adolescents to male ado-lescents and middle-aged women change?” “What contribution can teachers of health care education make to protect people from anorexia and intervene and help with already existing prob-lems?”Method: In order to answer the questions above, a critical examination and literature research of national and international research results take place.Outlook: According to the Austrian Health Care Structure Plan (ÖSG), Vi-enna would need 128 to 208 beds in child and adolescent psychiatry. However, there are currently only 56 beds available (cf. BMG 2012). In Styria, meanwhile, there does not even exist a specific institute for child and adolescent psychiatry. The number of anorexic patients, however, is increasing steadily. Thus, Austria needs to raise awareness with regard to anorexia concerning persons from all population groups and selected oc-cupational groups.
