[Health economic evaluation of health promotion - the example "fit for pisa"].

The increasing prevalence of risk factors associated with physical inactivity lead to an economic burden on society. The article uses the example of the prevention measure "fit for pisa" to investigate to what extent a full economic evaluation can provide a basis for decision-makers. The intervention integrated the daily physical education at 5 primary schools in Göttingen for the entire school term. The study is intended to provide information on short- and long-term potential savings. A process analysis identified the prevention performance from a societal perspective. Resource consumption was recorded in (partly) standardisedform and evaluated and also revealed the need for investment in sports halls with capacity to expand the programme to all primary schools in Göttingen. In the routine the implementation costs of half-day schools are 619 € per student year; for all-day schools 236 € per student year. The consideration of the short-term outcomes shows that TV viewing has decreased and physical activity has been strongly encouraged. The active life style promotion has shown an improvement on BMI in the medium-term. On the basis of a decision analytical model, a cost-benefit analysis of the program over the life course will be undertaken. © Georg Thieme Verlag KG Stuttgart · New York.
