The purpose of this study was to find predictors of 10-year survival a
mong 70-year olds and to show that there might be more than one good s
et of predictors. All variables found to be significantly related to s
urvival in univariate tests (predictors) are given a risk value (0 = n
o risk, 1 = risk) and classified into high-order domains. The number o
f domains containing predictors with risk values are then counted, giv
ing the individual a certain risk index. The method was applied on dat
a from the longitudinal population study of 70-year-old people in Goth
enburg, Sweden, the H70-study. In a random sample of 474 men and 562 w
omen predictors for survival over a 10-year period, from the age of 70
, were selected for men and women, respectively. The predictors were c
lassified into seven domains: socio-economic status, life style, socia
l networks, need of help, biomarkers of ageing, physical health and co
gnitive function. The analysis revealed a consistent pattern in which
survival was related to the number of risk domains, In the no-risk sub
-sample 12.5% of the men were deceased after 10 years, in the sub-samp
le with five or more risk domains involved 78.0% were deceased. The co
rresponding figures for women were 10.0% and 60.0%. The results show t
hat it is possible to find variables that can predict survival. Howeve
r, there is not only one set of good predictors, As an alternative to
use of specific variables as predictors the presumptive predictors can
be grouped into a few main domains and good predictions be made on th
e basis of these domains.
