Primiparous women of childbearing age who had given birth at least 6 months previously were invited to participate in the present cross-sectional study, which was conducted from October 2011 to April 2012 in the Chaoyang District of Beijing. Time since birth was divided into the following 4 periods: less than 1 year, 1-5 years, 6-10 years, and more than 10 years. The factors associated with CPP status were analyzed using logistic regression.
Among the 1456 participants, CPP was more common following cesarean delivery (11.2% versus 6.9% among women with a vaginal delivery; P = 0.007), and the rate of CPP increased with time since birth (2.3%, 9.3%, 10.7%, and 13.1% for the 4 specified time periods, respectively (P < 0.001). Cesarean delivery, longer time since birth, and CPP were all associated with a lower HRQoL utility score.
Although the absolute risks were small, cesarean delivery and time since birth were significant risk factors for CPP, which had a negative impact on the participants鈥?HRQoL.
