[Individual risk factors, health behaviour and mortality developments in Germany from 1984 to 1998].
The aim of the study is to investigate the contribution by the risk factors smoking, overweight, high blood pressure, physical inactivity and regular alcohol consumption to the total mortality development of the general population in Germany. Data are a mortality follow-up conducted by the Federal Institute for Population Research during 1984 - 1998 in West Germany and 1991-1998 in East Germany. 8474 persons participated at baseline in West Germany in the age group 31-69 years, and 1546 persons participated at baseline in East Germany in the age-group 40-79 years. The vital status in the year 1998 could be determined in West Germany for 86.5% and in East Germany for 97.0%. In the observation period 1986-1998 for West Germany 17.2% of the males died and 8.6% of the females. In East Germany between 1991-1998 9.6% of the males died and 6.7% of the females. The statistical analysis, based on the Cox regression showed for West Germany except for overweight in males throughout a significant contribution of the risk factor load on total mortality. The highest relative risks were found for strong smokers (males: RR = 3.47, p < 0.001, females: RR = 3.62, p < 0.001). The relative mortality risk for persons with three and more risk factors yielded in males 4.88 (p < 0.001) and in females 5.05 (p < 0.001). These findings clearly demonstrate that already a few risk markers of the individual health behaviour have a strong impact on the total mortality development in Germany. The mortality risk is about five times higher for persons with three and more risk factors. This indicates the need for preventive measures targeting high-risk population groups.
