Resumption of sexual intercourse post partum and the utilisation of contraceptive methods in China: a cross-sectional study

Abstract

ObjectiveThis is a cross-sectional study that aimed to examine the resumption of sexual intercourse post partum, the utilisation of contraceptive methods and the influencing factors among Chinese women at a tertiary teaching hospital.DesignThis is a questionnaire survey by written and online interview for participants.ParticipantsBased on medical records, we sent online questionnaires about postpartum sexual intercourse and contraception plans to 550 eligible women.Main outcome measuresPotential factors affecting postpartum sexual intercourse and utilisation of contraception were determined by analysis of epidemiological and clinical factors and sexual experiences during and after pregnancy.ResultsOf 550 eligible participants, 406 women (73.8%) with a postpartum period of 8.5 months (range 6–10) completed the questionnaires; 146 of 406 (36.0%) resumed sexual intercourse within 3 months, and 259 of 279 (92.8%) used contraceptive methods. In univariate and multivariate analyses, sexual intercourse during pregnancy (adjusted OR 4.4, 95% CI 2.8 to 6.9) and resumption of menstruation (adjusted OR 2.5, 95% CI 1.5 to 4.3) were significant influencing factors in resumption of sexual intercourse within 3 months after childbirth. No factor was found to be associated with using contraceptive methods or the general resumption of sexual intercourse post partum. The questionnaire had good reliability and validity.ConclusionsHaving sexual intercourse during pregnancy and resuming menstruation earlier were independent factors for resumption of sexual intercourse within 3 months after delivery. Almost all women who had postpartum sexual intercourse used various contraceptive methods.
