In this thesis the impact of in-utero influenza exposure on socioeconomic status and survival in adult life is studied. The data used is a subset of a longitudinal level database for Scania for 1815 to 1910. In this thesis the outbreak of influenza pandemic in 1833 is used as a natural experiment. The pathway model used in this thesis allows for both direct effect on the survival form the in-utero influenza exposure and indirect effects mediated through socioeconomic status in adult life for the individual. The analysis is done separately for women and men, and support for “Fetal origins hypothesis” as a negative effect on survival in later life is found for both sexes
