Few longitudinal studies have examined women's experiences of sex after childbirth. Much of the advice given to couples about what to expect in relation to sex after childbirth is based on cross-sectional studies.
To investigate timing of resumption of sex after a second birth and assess associations with obstetric factors (method of birth and perineal trauma) and time interval between first and second births.
Prospective cohort of 1507 nulliparous women recruited before 25 weeks' gestation in Melbourne, Australia followed up at 3, 6, 9, and 12 months after first births, and 6 and 12 months after second births. Measures include: obstetric factors and resumption of vaginal sex after first and second births.
By 8 weeks after their second birth, 56% of women had resumed vaginal sex, compared with 65% after their first birth. Women were more likely to resume sex later than 8 weeks postpartum if they had a spontaneous vaginal birth with episiotomy or sutured perineal tear (aOR: 2.21, 95% CI: 1.5-3.2), operative vaginal birth (aOR: 2.60, 95% CI: 1.3-5.3) or cesarean delivery (aOR: 2.15, 95% CI: 1.4-3.3) compared with a vaginal birth with minimal or no perineal trauma. There was no association between timing of resumption of sex and the time interval between births.
For almost half of the cohort, sex was not resumed until at least 8 weeks after the second birth. Timing of resumption of sex was influenced by obstetric factors, but not the time interval between births.
很少有纵向研究调查过女性产后的性生活体验。许多关于产后性生活的建议都是基于横断面研究得出的。
调查第二次分娩后恢复性生活的时间，并评估与产科因素（分娩方式和会阴创伤）和两次分娩之间的时间间隔相关的因素。
这是一项前瞻性队列研究，招募了 1507 名在澳大利亚墨尔本妊娠 25 周前的初产妇，在首次分娩后 3、6、9 和 12 个月以及第二次分娩后 6 和 12 个月进行随访。研究内容包括：产科因素以及首次和第二次分娩后恢复阴道性生活的情况。
在第二次分娩后 8 周时，有 56%的女性恢复了阴道性生活，而首次分娩后有 65%的女性恢复了性生活。如果女性自然分娩伴有会阴侧切或会阴裂伤（优势比：2.21，95%置信区间：1.5-3.2）、产道分娩（优势比：2.60，95%置信区间：1.3-5.3）或剖宫产（优势比：2.15，95%置信区间：1.4-3.3），与会阴无创伤或轻微创伤的阴道分娩相比，她们恢复性生活的时间更晚。性生活恢复时间与两次分娩之间的时间间隔之间没有关联。
对于近一半的队列，直到第二次分娩后至少 8 周，才恢复性生活。性生活恢复时间受产科因素影响，但与两次分娩之间的时间间隔无关。
