Abstract: Objective：To evaluate the effects of the contraceptive guide and service after artificial abortion on reducing the repeated abortion and gynecological diseases. Methods：900 women with gynecological diseases received induced abortion were divided into two groups, Observation group with the contraceptive guide and service and control group without. Telephone follow-up was performed for one year after operation. The differences of contraceptive choice, repeated abortion rate and the effect on gynecological diseases were compared between two groups. Results：IUD and male condoms were the top two choices in observation group, while IUD and contraceptive drugs were the top in control group. Observation group had higher rates of IUD and male condoms, and its rate of male condoms was significantly higher than that of control group（χ2=28.145, P＜0.01）. The rates of oral contraceptives and coitus interruptus in control group were higher than those in observation group（P＜0.05）. The rate of repeated abortion in control group was significantly lower than that in observation group（19.29% vs. 30.63%, χ2=15.22, P＜0.01）. The factors related to repeated abortion included failing IUD, failing condom, failing oral contraceptives, the rhythm method, coitus interruptus and not use any contraception. By multivariate Logistic regression analysis, safety period contraception, not contraception, and in vitro ejaculation were the independent risk factors of contraceptive failure of repeated abortion. Conclusions：The contraceptive guide and service after abortion allows women to choose the efficient contraceptive methods, which reduce the risk of gynecological diseases and the rates of unwanted pregnancy and repeated abortion.
