Abortion is the termination of pregnancy before 20 weeks of gestation or with a fetal weight of <500 grams, either spontaneous or induced. This condition is one of the serious pregnancy complications as it can lead to bleeding, infection, and even maternal death. Objective: This study aimed to determine the factors associated with the incidence of abortion among pregnant women at Harapan dan Doa Regional Public Hospital, Bengkulu City. This research used a case-control design with a 1:1 ratio. The sample consisted of 252 respondents, including 126 abortion cases obtained through total sampling and 126 controls selected using simple random sampling. Bivariate analysis showed a significant association between age (p=0.00), history of abortion (p=0.046), and the incidence of abortion, whereas parity was not associated (p=1.000). The most dominant factor associated with abortion was age, with a p-value of 0.001 and an Odds Ratio (OR) of 3.265. Age and history of abortion are associated with the incidence of abortion, with age being the most dominant factor. Health workers are expected to increase education and monitoring for high-risk pregnant women, particularly those under 20 year, over 35 years, and with a history of abortion.
