title: [Development of reproductive health in women in the Czech Republic 1993-1997. IV. Relation between contraception and induced abortion].
abstract: OBJECTIVE
  Overall objective is to detect changes in reproductive health of women due to changes in the system of social and health care. The particular objective of this part of the study (part IV) is to identify the changes in the relationship of decreasing number of induced abortions and increased use of contraception in 1997 compared to 1993.
  
  
  METHODS
  Retrospective comparative epidemiological study.
  
  
  METHODS
  Institute for the Care of Mother and Child, Praha 4--Podolí.
  
  
  METHODS
  Input data for the comparison of number of induced abortions and extent of contraceptive use came from the results of two previous parts of the study (parts II and III). The relationship of contraceptive use and induced abortions was analyzed with regard to possible effect of concurrent development of selected social-demographic factors.
  
  
  RESULTS
  The highest decrease of absolute number of induced abortions, together with higher-than-average decrease of absolute number of women not using one of three effective methods of contraception, was among married women, women with two children and women with secondary education without exam. On the opposite, the highest relative decrease of women not using one of the three contraceptive methods was among women 20-24 year of age, women without children and women with university education, although such change was not reflected in relative decrease of number of induced abortions in these groups. Furthermore, their relative decrease was even smaller than the national average. Similarly, the highest relative decrease of number of induced abortions among divorced women and women 25-29 year of age was linked with less-than-average decrease of number of women not using one of three effective methods of contraception.
  
  
  CONCLUSIONS
  Different values of changing relationship of contraception and induced abortions in relation to analyzed social-demographic factors during period of observation document the influence of these factors without dispute. Due to complex influence of these factors on the relationship of contraception and induced abortions, the particular contribution of each of them is difficult to asses during simple analysis one-by-one.
