title: Determinants of first and second trimester induced abortion - results from a cross-sectional study taken place 7 years after abortion law revisions in Ethiopia.
abstract: BACKGROUND
  In 2005 Ethiopia took the important step to protect women's reproductive health by liberalizing the abortion law. As a result women were given access to safe pregnancy termination in first and second trimester. This study aims to describe socio-economic characteristics and contraceptive experience among women seeking abortion in Jimma, Ethiopia and to describe determinants of second trimester abortion.
  
  
  METHODS
  A cross-sectional study conducted October 2011 - April 2012 in Jimma Town, Ethiopia among women having safely induced abortion and women having unsafely induced abortion. In all 808 safe abortion cases and 21 unsafe abortion cases were included in the study. Of the 829 abortions, 729 were first trimester and 100 were second trimester abortions. Bivariate and multivariate logistic regressions were used to determine risk factors associated with second trimester abortion. The associations are presented as odds ratios (OR) with 95% confidential intervals. Age stratified analyses of contraceptive experience among women with first and second trimester abortions are also presented.
  
  
  RESULTS
  Socio-economic characteristics associated with increased ORs of second trimester abortion were: age < 19 years, being single, widowed or divorced, attending school, being unemployment, being nullipara or para 3+, and having low education. The contraceptive prevalence rate varied across age groups and was particularly low among young girls and young women experiencing second trimester abortion where only 15% and 19% stated they had ever used contraception.
  
  
  CONCLUSIONS
  Young age, poor education and the prospect of single parenthood were associated with second trimester abortion. Young girls and young women were using contraception comparatively less often than older women. To ensure women full right to control their fertility in the setting studied, modern contraception should be made available, accessible and affordable for all women, regardless of age.
