Abstract:
Objective:To analyze the contraceptive measures and the risk factors of accidental pregnancy in Chinese women within 2 years after delivery.Methods:In 60 hospitals in 15 provinces in eastern, central and western China, 300 pregnant women were randomly surveyed in each hospital by telephone from July 2015 to June 2016, including postpartum breast-feeding, menstrual and sexual recovery, contraceptive measures, and accidental pregnancy. The contraceptive measures and risk factors of accidental pregnancy in 2 years after delivery were analyzed.Results:Of the 18 045 women surveyed, 15 328 women (84.9%) had used contraception within 2 years after delivery. The rate of 2-year accidental pregnancy was 7.16% and 71.88% occurred between 7 and 18 months postpartum. The rate of accidental pregnancy at different postpartum periods was statistically significant ( P<0.001). There were statistically significant differences in the composition ratio of condoms, long-acting contraceptive methods, combination oral contraceptives and other (emergency contraception/spermicide) contraceptive methods in eastern, central and western regions ( P<0.001, P<0.001, P=0.01, P<0.001). Single factor analysis showed that maternal age, nationality, education level, region, delivery way, delivery times, No. of pregnancies, postpartum contraceptive method, postpartum contraceptive start time, postpartum sexual recovery time, postpartum menstrual recovery time, and breastfeeding time were related to the rate of 2-year accidental pregnancy (all P<0.001). Multivariate logistic regression analysis showed that the region ( P<0.001), maternal age ( P<0.001), education level ( P<0.001), nationality ( P=0.01), No. of pregnancies ( P=0.04), delivery times ( P=0.02), breastfeeding time ( P<0.001), delivery way ( P=0.01), postpartum contraceptive methods ( P<0.001), postpartum menstruation recovery time ( P=0.01) and postpartum contraception startup time ( P=0.02) were the risk factor of 2-year accidental pregnancy. Conclusion:Accidental pregnancy rate in 2 years after delivery is higher in Chinese women. In order to reduce the harm of accidental pregnancy to maternal and child health, China should further improve the postpartum contraception education and service system, promote the service object-centered contraceptive counseling method and individual contraception plan.
