Objectives:
The aim of the study is to investigate the association between personal support and mortality experience in Germany.
Methods:
Data source is the Life Expectancy Survey of the Federal Institute for Population Research (Wiesbaden). This study comprises the National Questionnaire Survey of the German Cardiovascular Prevention Study (1984-86) and a mortality follow-up (1998). Included are 7240 persons with German nationality aged 31-69 years at baseline. 957 persons (13.2%) died during the observation period from 1984-1998. An additive index combining familiy status and number of persons available in emergency situations was administered as indicator for social support. The multivariate statistical analysis was performed with the cox-regression method.
Results:
Persons with low or very low personal support yielded in both sexes significantly higher relative risks for mortality during the 14 years of follow-up. The relative risks in the regression models including confounding factors for low personal support were 1.49 (p < 0.01) in males and 1.67 (p < 0.01) in females, and for very low personal support 1.81 (p < 0.05) in males and 2.31 (p < 0.01) in females.
Conclusions:
These results are indicating an increasing importance of personal support for the mortality experience in the general population.
