Factors associated with postpartum resumption of sexual intercourse among women in China: A retrospective multicenter study.

OBJECTIVE

To examine the prevalence and factors associated with early resumption of sexual intercourse among postnatal women in China.

METHOD

We conducted a retrospective multicenter study of 15 834 postpartum women from 60 hospitals in 15 different locations across China. Data were obtained from questionnaires administered to the participants. All dates were analyzed using a one-way ANOVA and two-level Cox multiple linear regression models.

RESULTS

More than half of the participating women (55.9%) resumed sexual intercourse by 3 months postpartum. The independent variables associated with the postpartum resumption of sexual intercourse included sociodemographic characteristics (age, geographic location, educational attainment) and medical histories, including the previous abortion (incorporate with spontaneous and voluntary abortion) frequency, menstrual recovery, exclusive breastfeeding, and number of living children (p < 0.05).

CONCLUSION

More than half of the women in this study resumed sexual intercourse within 3 months postpartum. Women with a lower educational attainment and from the western regions of China were more likely to resume sexual intercourse earlier. Increasing age, delayed recovery of menses, and exclusive breastfeeding were associated with a delayed resumption of sexual intercourse. Women who had greater experience with abortion or the number of living children resumed sexual intercourse earlier than their counterparts.
