While a large body of literature is concerned with the interplay of he
alth and poverty in developing countries, comparable studies for devel
oped countries are rare. Using data drawn from the German Socio-Econom
ic Panel (GSOEP), this paper investigates the relationships between ch
anges in relative income poverty, income changes and health-related qu
ality of life in Germany, i.e. in an environment with nominally equal
access to medical care, education and social security. A fundamental f
ive-dimensional health concept is introduced and tested for its empiri
cal performance. The background of the causal analysis is formed by tw
o hypotheses, one regarding low income as a possible cause for poor he
alth (prevention hypothesis) and the other assuming the opposite causa
l direction (deprivation hypothesis). By means of a descriptive analys
is and a structural equations model, the existence of a more complex r
elational web between health and poverty is demonstrated. (C) 1997 Els
