title: [Importance of registry of parturient data].
abstract: OBJECTIVE
  Analysis of the influence of age changes from younger parturients to older ones on the perinatal care results.
  
  
  METHODS
  Retrospective epidemiological study of maternal age and other selected indicators.
  
  
  METHODS
  Institute for the Care of Mother and Child, Prague 4-Podolí.
  
  
  METHODS
  Comparison of selected biological and social risk factors, obstetrical interventions, and perinatal mortality in maternal age groups.
  
  
  RESULTS
  During the shift from younger to older groups of parturients there is consistent pattern of higher perinatal mortality among the youngest and older ones. The same pattern is preserved while analysed by social risk factors and risk factors from obstetrical history. In contrast, most of selected obstetrical parameters increased continuously with the increasing age of mother. The final perinatal mortality figure is a result of complex influence of all negative factors and the obstetrical intervention to paralyse them. The recent shift from the youngest mothers to older groups has had some positive impact, however the further increase of mothers 30 years old and older may show some negative influence on perinatal care results.
  
  
  CONCLUSIONS
  The age shift among parturients from younger to older age groups contributed to decrease of perinatal mortality in the Czech Republic in late nineties. We suggest a possible negative influence of further increase of pregnant women 30 years old and older on the current results of perinatal care.
