[Social differences in infant mortality in a longitudinal Turin study]

The Turin longitudinal study enables to study the one-year survival of children born to any member of the study population and to relate the still-born and infant mortality to the parents' census characteristics. In this paper 25,108 children, born between 1981 and 1985 of parents residents in Turin at the 1981 population census, were followed up with respect to one-year survival. The numbers of infant deaths have been observed according to parents' education, housing ownership, occupational status and professional position. Only parents' education showed consistent differential in the still-born and infant mortality risks, adjusted for maternal age.
