This study have been carried out to: a) investigate the prevalence of such occupational factors in parents which could be fatal to their children, and b) evaluate quantitatively the risk of mortality in infants caused by some leading diseases developed as a result of harmful occupational factors to which their parents had been exposed. During this work the data bank on infant mortality in Tallinn based on deaths registration in city archive for period 1968-1992 has been created. This bank includes the data on parents' occupation. The prevalence of parents' occupational risk factors has been analyzed in infants who die due extreme immaturity and other prematurity cases, congenital anomalies neoplasias and control group persons. To evaluate the death risk in children the case-control epidemiological study with the individual group selection has been performed. This pilot analytical epidemiological study allows to suppose involving of possibly harmful occupational factors which are playing a certain role influencing mortality in whole contingent investigated, but not concerning individual nosologic forms. For the final judgement concerning the role of occupational risk factors the additional special fundamental study including the extended number of observations and the data, on interrupting nonoccupational risk factors prevalence should be carried out.
