Objective  To analyze the changes of high risk factors of induced abortion women before and after the comprehensively opening of three-child policy.

Methods  Clinical information of pregnant women who underwent high-risk induced abortion from January to December 2021 was retrospectively analyzed. According to the opening time of the three-child policy (July 1, 2021 as the boundary), they were divided into before three-child policy group (n=1 441) and after the three-child policy group (n=1 384). The changes of high risk factors in women with induced abortion were compared and analyzed.

Results  There were statistically significant differences between the two groups in education background, marital status, vaginal delivery history, cesarean section history, multiple abortion history and missed abortion history, postoperative contraceptive methods and unwanted pregnancy (P < 0.05). There was statistical significance between the two groups in the combination of two high risk factors and below (P < 0.05).

Conclusion  With the opening of the three-child policy, women's willingness to give birth gradually increased, and the overall abortion rate is decreased, which is conducive to the protection of female reproductive health.
