To investigate the situation and the influencing factors of abandoning long-acting reversible contraception(LARC) of women with unwanted pregnancy within one year after induced abortion. Methods: From January 2022 to December 2022, 1035 women with induced abortion were treated with LARC and were followed up for 1 year, and the situation of the abandoning LARC of the women was observed. These women were divided in group A(189 cases with the abandonment of LARC) and group B(846 cases with LARC continuing used). The reasons of the abandoning LARC of the women after abortion were investigated. The risk factors of the abandonment of LARC of the women with abortion were analyzed by univariate analysis and multivariate logistic regression. Results: In 1 year of follow-up after induced abortion, there were 189(18.4%) women with the abandonment of LARC, and the reasons of the abandonment of LARC included the adverse reactions(83 cases), the psychosocial factors(100 cases) and other reasons(6 cases). Multivariate logistic analysis showed that the younger age, the no childbearing history, the no repeated abortion and the lower education level of high school of the women were the risk factors for their abandoning LARC(OR=1.657, 1.669, 2.442, 1.790, P<0.05). Conclusion: The women with LARC after induced abortion because of unwanted pregnancy still have a certain percentage of abandoning LARC, and which are influenced by many factors. The pre-abortion consult and the post-abortion management for the women should be strengthen in clinic, and the targeted intervention measures should be conducted to improve the implementation rate of LARC of the women after abortion.
