Methods From January 2013 to April 2014, a total of 782 cases of women with repeated ATP in Shenzhen Family Planning Service Center, Shenzhen Yantian District People′s Hospital and the other seven medical institutions were selected as research subjects. They were randomly divided into intervention group (n=388) and control group (n=394) by random digits table. Intervention group received personalized contraceptive guidance, and control group only received a conventional contraceptive knowledge education. The rate of using contraceptive measures before ATP , and 1-, 6-, and 12-month after ATP, and unintended pregnancy rate within 12 months after ATP in the two groups were observed and statistically analyzed. All the patients signed the informed consents.
Results ①There were no statistical differences among the age, gravidity, parity, interval time between the latest two times of ATP, the rate of repeated ATP in the latest half a year between the two groups (P>0.05). ②Before the ATP, there was no statistical difference in contraception rate between the intervention group (47.4%, 184/388) and control group (48.7%, 192/394) (P>0.05). But 1-, 6- and 12-month after ATP, the contraception rates in intervention group all were obviously higher than those in control group, and all the differences were statistically significant (χ2=126.532, 73.869, 72.894; P=0.000). And 1-, 6- and 12-month after ATP, the usage of condoms was both the highest in the two groups among all contraceptive measures, and the usage of condoms in intervention group all were obviously higher than those in control group, and all differences were statistically significant (χ2=15.521, 33.712, 21.628; P=0.000). One month after ATP, the rate of using oral contraceptives in intervention group was obviously higher than that in control group, and the difference was statistically significant (χ2=62.826, P=0.000). ③Within 12-month after ATP, the unintended pregnancy rate in intervention group was obviously lower than that in control group, and the difference was statistically significant (χ2=7.202, P=0.007).
Conclusions Personalized contraceptive guidance intervention method can improve the effective rate of contraception in women underwent repeated artificial abortion operation, and can reduce the incidence of unwanted pregnancy, it is worthy of clinical promotion.
