The so called ''potentially lost life years'' of a population are most
ly due to unfavourable lifestyle and lack of health orientation. This
could be shown e.g. in view of job-stressors and their consequences fo
r cardio-vascular disease. As important the single risk factor may be,
as limited is their impact when we look at the amount of explained va
riance, mostly only around 10%. On the other hand each examined popula
tion includes a larger amount of individuals who will not fall ill in
spite of identical stressors as those getting sick. This ability to re
sist, based on special interior and exterior resources, is now called
salutogenesis. It stands opposite to the term pathogenesis. More recen
t research in that area examines favourable exterior resources such as
structures in ''social support'', favourable conditions at the work-p
lace, in the family and so on. Other more personality oriented abiliti
es include optimism, hardiness, etc. The founder of the theory on salu
togenesis, AARON ANTONOVSKY, describes a concept of ''sense of coheren
ce'' including (1.) comprehensibility, (2.) manageability, (3.) meanin
gfulness. More recent therapeutic concepts are based on these assumpti
ons and have proved to be successful.
