Abstract:Objective To systematically evaluate the risk factors of stress urinary incontinence (SUI) in Chinese women. Methods The electronic databases of PubMed,Web of Science,Cochrane Library,Clinicalkey,CNKI,VIP,WanFang Data and SinoMed were searched to collect case control studies,cohort studies and cross sectional studies on risk factors of SUI in Chinese women.The retrieval time was from the establishment of each database to May 2020.After two researchers independently screened the literature,extracted the data and assessed the risk of bias in included studies,Meta analysis was performed by Revman 5.3 software. Results Thirty five studies involving 94 043 participants were included,and 20 potential risk factors were eventually evaluated.Meta analysis showed that the following factors were risk factors of female SUI in China,including increasing age ［OR=2.39,95%CI (2.02-2.82)］,higher labor intensity ［OR=1.48,95%CI (1.30-1.69)］,higher BMI ［OR=1.61,95%CI (1.44-1.81)］,history of alcohol consumption ［OR=1.38,95%CI (1.25-1.53)］,hypertension ［OR=1.68,95%CI (1.35-2.08)］,constipation ［OR=1.62,95%CI(1.46-1.80)］,history of respiratory diseases ［OR=2.46,95%CI (2.15-2.81)］,urinary system diseases ［OR=2.31,95%CI(1.90-2.80)］,gynecological diseases ［OR=3.02,95%CI (1.35-6.72)］,more times of pregnancy ［OR=1.33,95%CI (1.08-1.63)］,bearing birth more than three times ［OR=1.53,95%CI (1.39-1.68)］,heavier birth weight of the first born child ［OR=2.10,95%CI(1.13-3.91)］,perineal lacerations［OR=1.51,95%CI(1.32-1.73)］,vaginal delivery ［OR=1.91,95%CI (1.55-2.36)］,menopause ［OR=1.80,95%CI (1.48-2.19)］,history of pelvic surgery ［OR=2.15,95%CI (1.47-3.15),uterine prolapse ［OR=2.21,95%CI (1.68-2.91)］(P＜0.05,P＜0.01).Cesarean section was a protective factor for SUI in Chinese women［OR=0.71,95%CI(0.51-0.97),P=0.03］. Conclusions Increaing age,higher BMI,higher labor intensity,history of drinking,higher blood pressure,constipation,history of respiratory diseases,history of urinary system diseases,history of gynecological diseases,more pregnancy times,birth times (≥3 times),first baby′s birth weight,perineum laceration,vaginal delivery,menopause,history of pelvic surgery,and uterine prolapse are risk factors for SUI in Chinese women,while cesarean section is a protective factor for SUI in Chinese women.For the high risk female patients with the above risk factors of SUI,protection should be strengthened and appropriate intervention measures should be taken in order to reduce the incidence of SUI and improve the life quality of them.
