Objective: To evaluate whether social-economic changes in the Czech Republic in 90’s influenced selected demographic indications in population of mothers. Design: Retrospective comparative epidemiological study. Setting: Institute for the Care of Mother and Child, Praha 4-Podolí, Office of Health Information and Statistics, Praha. Methods: Comparative analysis of selected demographic data and pregnancy history data collected according to the WHO recommendations on the innovated „Report on mother“ of the Office of Health Information and Statistics database in 1997–2000. Results: Nation-wide return rate of 99.89% of „Report on mother“ forms confirms the representativeness of analyzed data. During the 4-year-period we demonstrated increase of maternal age, level of education, and proportion of single mothers. We observed decrease in proportion of mothers with second baby and mothers with induced abortion in history. The proportion of mothers with drug abuse during pregnancy was increasing and their age was decreasing. Characteristics of these changes suggest possible association with social and economic changes in the Czech Republic in 1990’s. Conclusions: In second-half of 90’s we observed increase of maternal age, educational level, proportion of single mothers and decrease of proportion of mothers delivering for the second time and mothers with history of induced abortion. Drug abuse during pregnancy is most frequent among youngest mothers.
