Abstract
It is known that medical birth registries are valuable sources of information on birth defects. They are widely used for their monitoring and control. Currently, the medical birth registries which are established in Murmansk County allow to study the birth prevalence of birth defects and trends in prevalence since 1973, including the period of socio-economic transformations and changes in medical practice caused by introduction of prenatal screening. The aim of this study was to demonstrate the effectiveness of using existing medical birth registries in Murmansk County for the surveillance of birth defects and detecting their risk factors. We found, that medical birth registries in Murmansk County can be successfully used for monitoring and control of the prevalence of birth defects as well as for epidemiological investigations because of full coverage of population and prospective collection of data on both an outcome and a prenatal condition.
