Abstract
Bioarchaeological and clinical data show that diet influences health, and this relationship is crucial to
how we understand past health with respect to sex and age. We propose a new method that coinvestigates the relationship between mortality risk and diet in the past. Our method integrates dietary
stable isotope data (δ13 Carbon and
δ
15 Nitrogen) from Roman Britain (N=659) with hazards analysis.
The results show that these data can be informatively used in this type of analysis in general, and that
in the context of Roman Britain, higher
δ
13C is associated with lower risks of mortality while higher
δ
15N is associated with elevated risks of mortality. Importantly, the results emphasize that a
bioarchaeological approach to interpretation must be taken in order to more fully understand the
results obtained by the method
