Abstract
Objective: This study aimed to assess the prevalence and factors associated with pelvic organ prolapse (POP) in a representative sample of Chinese urban women. Methods: A total of 29613 Chinese urban women were recruited to this cross-sectional study between February 2014 and March 2016. The prevalence of POP, defined as any stage Ⅱ or higher POP resulting in symptoms, was assessed using questionnaires and physical examinations. Multivariable logistic regression was used to assess factors associated with POP. Results: 2 864 of 29 613 women (9.67%) had POP. The prevalence of POP increased with age ranging from 1.23% (82/6 646) of women aged between 20 and 29 years to 26.11% (727/2 784) for those aged 70 years or older (P<0.000 1). Overweight and obese women were more likely to have POP than normal weight women [AOR=1.56, 95%CI 1.42-1.72 vs AOR=1.74, 95%CI 1.48-2.03]. In the multivariate analysis, the independent risk factors were cough (AOR=1.70, 95%CI 1.44-2.02), constipation (AOR=2.05, 95%CI 1.82-2.32), physical disease (AOR=1.27, 95%CI 1.15-1.41), and gynecological diseases (AOR=2.08, 95%CI 1.89-2.29). Nulliparous (AOR=0.12, 95%CI 0.06-0.22) and caesarean section (CS) (AOR=0.55, 95%CI 0.47-0.64) were protective factors for POP. Conclusions: POP affects nearly 10% of women in Chinese urban region. The prevalence of POP increases significantly with age. The independent risk factors for POP are body mass index, cough, constipation, physical disease and gynecological diseases. Nulliparous and CS are protective factors for POP.
