Prevalence and related risk factor of pelvic organ prolapse in the general Korean population / 대한산부인과학회지

ABSTRACT

OBJECTIVE: The aim of our study is to evaluate the prevalence and related risk factor of pelvic organ prolapse in the general Korean population. METHODS: The study population considered of 713 women who were seen for routine gynecologic health care. Pregnant or women within 6 weeks postpartum were excluded. General biographic data were collected regarding obstetric history, medical history, and surgical history. Pelvic organ support was measured and described according to the Pelvic Organ Prolapse Quantification (POP-Q) staging system. Univariate analyses of categorical data were performed with x2 test. RESULTS: The subjects had a mean age of 41.6 years (18-72), weight 55.8 kg (40-83), height 158.7 cm (138-177), body mass index (BMI) 22.3 kg/m2 (15.7-32), waist circumference (WC) 72.3 cm (58-91), and median parity was 2 (0-6). In the 713 women with a uterus, the rate of anterior vaginal prolapse was 27.6%, uterine prolapse 2.0%, and posterior vaginal prolapse 25.4%. The overall distribution of pelvic organ prolapse quantification system stages were as follows: stage 0, 68.3%; stage 1, 19.9%; stage 2, 11.2%; and stage 3, 0.6%. Age, parity, BMI, WC, pelvic floor muscle score, menopausal status and delivery mode were significantly associated with presence of prolapse. CONCLUSION: The prevalence of any degree of prolapse is 31.7%. Prevalence of anterior and posterior vaginal prolapse is higher than uterine prolapse. There was a statistically significant trend toward increased POP-Q system stage of support among women with many of the historically quoted etiologic factors for the development of pelvic organ prolapse.
