Methods CNKI, Wanfang, Weipu database, PubMed and Embase were searched for randomized controlled trials of contraceptive intervention and routine nursing. Literature was screened and data were extracted according to inclusion and exclusion criteria. After quality evaluation, meta analysis was performed with RevMan 5.2 software. Results Twenty-three randomized controlled trials were included, with a total of 16 684 subjects followed up. Metaanalysis showed that intervention could increase breastfeeding rates (OR=1.89,95%CI:1.42-2.51), and only the high-quality study intervention had no significant effect on the total nutritional rate of milk for five months after delivery (P=0.870). The intervention could increase the half-year contraceptive rate after delivery (OR=4.37, 95%CI：2.00-9.52), and the difference remained statistically significant after excluding low-quality studies (OR=0.17，95%CI: 0.13-0.21). The intervention could increase the one-year contraceptive rate after delivery (OR=2.83, 95%CI：1.67-4.82). The intervention could reduce the postpartum accidental pregnancy rate (OR=0.55, 95%CI：0.42-0.73), but the differences of four high quality studies were not statistically significant (OR=0.64, 95%CI：0.27-1.49). The intervention could reduce the rate of induced abortion (OR=0.35, 95%CI：0.26-0.47), but the quality of the documents that described the index was low. Conclusion Contraceptive interventions may affect postpartum breastfeeding rates, contraceptive rates, postpartum unintended pregnancy rates, and induced abortion rates. Because of the low quality of the inclusion of some documents, more large samples and high quality random control studies are required for further confirmation.Key words：postpartum   contraceptive intervention   randomized controlled trial   meta-analysis收稿日期: 2021-02-08     基金资助:陕西省科技厅重点研发计划项目(2020SF-026)通讯作者:单莉，Email：shan1lily@hotmail.com
