避孕方法知情选择表对剖宫产术后近期避孕行为的影响

Effect of informed selection table of contraceptive methods on short-term contraceptive behaviors of women after cesaraen section

目的研究建立避孕方法知情选择表以指导剖宫产后近期避孕,提高剖宫产后避孕措施的正确使用率,降低非意愿妊娠的发生。方法选取2015年3-5月于该院行剖宫产分娩的产妇共计306例,随机分为研究组和对照组,研究组采用避孕方法知情选择表及提供常规避孕咨询服务,对照组仅提供常规避孕咨询服务,随访产后2年两组的避孕行为及意外妊娠情况。结果研究组经常避孕的频率高于对照组(93.1%vs.74.7%,P<0.05)。研究组首次性生活避孕率高于对照组(82.5%vs.53.4%,P<0.05);前者服复方口服避孕药的比例高于对照组(17.5%vs.7.5%,P<0.05)。而对照组多次服紧急避孕药的比例(24.0%vs.11.3%)以及采用体外排精避孕的比例(14.4%vs.3.1%)更高(P<0.05)。两组采用宫内节育器、避孕套、安全期和曼月乐避孕的比例差异无统计学意义(P>0.05)。研究组意外妊娠发生率为3.1%,对照组为12.3%,两组比较差异有统计学意义(P<0.05)。结论避孕方法知情选择表有助于剖宫产后避孕措施的落实从而减少非意愿妊娠发生。

Objective To establish informed selection table of contraceptive methods,direct short-term contraception after cesaraen section,improve the correct usage rate of contraceptive methods after cesaraen section,and reduce the occurrence of unwanted pregnancy.Methods A total of 306 women giving birth to their babies in Chongqing Municipal Maternal and Child Health Care Hospital from March to May in 2015 were selected and randomly divided into study group and control group. The women in study group were given informed selection table of contraceptive methods and common contraception consultation service,while the women in control group were only given common contraception consultation service. The contraceptive behaviors and incidence rates of unwanted pregnancy within two years after delivery in the two groups were followed up. Results The frequency of contraception in study group was 93. 1%,which was statistically significantly higher than that in control group( 74. 7%)( P<0. 05). The contraceptive rate for first sexual life in study group was 82. 5%,which was statistically significantly higher than that in control group( 53. 4%)( P< 0. 05). The usage rate of compound oral contraceptive drugs in study group was 17. 5%,which was statistically significantly higher than that in control group( 7. 5%)( P < 0. 05). The proportions of women taking emergency contraceptive drugs repeatedly and citus interruptus in study group were 24. 0% and 14. 4%,respectively,which were statistically significantly higher than those in control group( 11. 3% and 3. 1%)( P < 0. 05). There was no statistically significant difference in the proportions of women using intrauterine device,condom,safe period,and Mirena for contraception between the two groups( P>0. 05). The incidence rates of unwanted pregnancy in study group and control group were 3. 1% and 12. 3%,respectively,there was statistically significant difference between the two groups( P < 0. 05). Conclusion Informed selection table of contraceptive methods is helpful for implementation of contraceptive methods after cesaraen section,so the incidence rate of unwanted pregnancy is reduced.
