To evaluate the German intervention model of "Community-related Behavioural Medicine" in reducing cardiovascular risk during a major prevention study (phase I) and to investigate the efficiency of a long-term evaluation by establishing a Local Health Information System for which cooperating primary care physicians carry responsibility (phase II). In the intervention city of Bruchsal (GCP evaluation, phase I), the cardiovascular risk factors were reduced: smoking (-9.4%), obesity (-17.1%), hypertension (-51.4%) and hypercholesteremia (-12.8%). In the general practices of Oestringen (LOHIS-evaluation, phase II), the prevalence of smoking, from 1992 to 1994 (-23.8%, p < 0.01) as well as hypertension (-22.2%), p < 0.01) continued to decrease; there was no further reduction of hypercholesteremia and over-weight.
