Abstract
Introduction and hypothesis
The literature is scarce regarding the effects of comorbidities, clinical parameters, and lifestyle as risk factors for pelvic organ prolapse (POP). This study was performed to systematically review the literature related to body mass index (BMI), waist circumference, diabetes mellitus (DM), hypertension (HT), dyslipidemia, chronic constipation, smoking, chronic cough, occupation, and striae and varicose veins as determinants for POP.
Methods
Search terms in accordance with Medical Subject Headings were used in PubMed, Embase, LILACS, and the Cochrane Library. Clinical comparative studies between women with and without POP and containing demographic and/or clinical raw data related to lifestyle and/or comorbidities were included. The ROBINS-I (risk of bias in non-randomized studies of interventions) instrument was used. Fixed-effects and random-effects models were used for homogeneous and heterogeneous studies, respectively.
Results
Forty-three studies were included in the meta-analysis. BMI < 25 kg/m2 was found to be a protective factor for POP [OR 0.71 (0.51, 0.99); p = 0.04], and BMI > 30 kg/m2 was a risk factor for POP [OR 1.44 (1.37, 1.52); p < 0.00001]. Waist circumference (≥ 88 cm) was reported as a risk factor for POP [OR 1.80 (1.37, 2.38); p < 0.00001], along with HT [OR 1.18 (1.09, 1.27); p = 0.04], constipation [OR 1.77 (1.23, 2.54); p < 0.00001], occupation [OR 1.86 (1.21, 2.86); p < 0.00001], persistent cough [OR 1.52 (1.18, 1.94); p < 0.0001]), and varicose veins [OR 2.01 (1.50, 2.70); p = 0.12].
Conclusions
BMI < 25 kg/m2 is protective while BMI > 30 kg/m2 is a risk factor for POP. Large waist circumference, dyslipidemia, HT, constipation, occupation, persistent cough, and varicose veins are also determinants for POP.
