The termination of unwanted pregnancies is a growing health-related issue around the world. This study used the 2017 Ghana Maternal Health Survey to examine the factors associated with the prevalence of induced abortion in Ghana. The study sample included 18,116 women of reproductive age who had a pregnancy in the 5 years preceding the survey. A multivariate logistic regression technique was applied. The prevalence of induced abortion was higher among women aged 25–34 years, those who had secondary-level education, those living in urban areas and in the Ashanti region, those of Akan ethnicity and those belonging to non-Catholic Christian denominations. Moreover, the prevalence was higher among single women, those who had no children, those who started sexual intercourse before the age of 18, those who were currently using a contraceptive, those exposed to media and those who knew about the legality of abortion. The multivariate analysis found that education, place and region of residence, marital status, ethnicity, current contraceptive use, religion, age at sexual debut, media exposure and knowledge about abortion legality were all significant predictors of induced abortion among women in Ghana. The study findings support a call for action to strengthen family planning services and educational programmes on induced abortion in Ghana to reach the target groups identified.
