Aim: Abortions, which are among the causes of maternal mortality in the world, continue to be important not only for women's health, but also because they have devastating physiological, psychological, and economic effects on the family and society. The present study aimed to determine the prevalence of total, induced, and spontaneous abortion in women aged 15-49 in a Family Health Center (FHC) region, and the factors affecting the abortion prevalence. Methods: This cross-sectional study was conducted with 311 women aged 15-49 registered between February and December 2017 at the FHC region in Northwest Thrace in Turkey. Results: The unintended pregnancy prevalence of the participants was 14.8%, and abortion prevalence was 22.2%. Spontaneous and induced abortions prevalence was 12.2% and 10.9%, respectively. According to the multivariate logistic regression analysis, the likelihood of abortion was significantly higher than the reference category in those who perceived their income at a bad level, current smokers, and those who considered abortion as a family planning method used to avoid unwanted pregnancies (p <0.05). The likelihood of induced abortion was significantly higher in women who perceived their income at a bad level, those with spouses aged 35 and older, and those whose spouses had primary school and lower levels of education (p<0.05). The likelihood of spontaneous abortion in women was higher in each one-unit increase in the total number of pregnancies, compared to those with high-school education, and those who perceived their income at a bad level (p<0.05). Conclusion: Nearly one out of every five women had undesired pregnancy experience, and one out of every four women had abortion experience. Spontaneous abortion prevalence was higher than that of induced abortion. Some sociodemographic and/ or obstetric characteristics are determinants of total abortion, induced abortion, and spontaneous abortion.
