[Overweight in Switzerland. Cross-comparison of various studies with the Heureka Study].

In this study the most important Swiss studies on the incidence of overweight and obesity are summarized and compared to the corresponding prevalence rates from the Heureka study. Interestingly, data on body weight indexes (mostly mass indexes) and the various prevalence rates showed good accordance for younger age groups. In the upper age classes however, phenotypic differences concerning determinants and risk factors for overweight became obvious in the different Swiss populations (i.e. from geographically different regions of Switzerland). Nevertheless, regional risk factors could not been detected because specific data were lacking. The importance of uniform weight definitions for studies as well as for daily practise is stressed.
