The high demand for abortion related services in Addis Ababa, Ethiopia indicates a reliance on abortion to control fertility and highlights an opportunity to increase access to contraceptives and improve post-abortion care. We analyzed the medical records of 1,200 women seeking abortion related services. Logistic regression was used to determine factors associated with use of modern or long-acting contraceptive post-abortion. Multivariate results illustrate that women aged 40-44, students, employed women, receipt of services in private clinics, number of children, and number of previous abortions were significantly associated with the odds of adopting any modern contraceptive post-abortion. The odds of choosing a long-active contraceptive method were significantly and positively associated with being age 25-29, attaining secondary or higher education, and number of children. Improved services and information along with reliable access to modern and long-acting contraceptives can reduce the need to use abortion to control fertility among women in Addis.
