Participants were followed through December 19, 2022. Incident POP was identified using International Classification of Diseases, Tenth Revision codes and operating procedure codes in the medical records. Cox proportional hazards model was used to estimate the association between obesity measures and incident POP. Population-attributable fractions were calculated to indicate the proportion of cases that were attributable to obesity measures.RESULTSDuring a median follow-up of 13.8 years, 9,781 POP cases were recorded. Central obesity (waist/height ratio 0.5 or greater) was associated with a 48% increased risk of POP regardless of BMI (hazard ratio [HR] 1.48; 95% CI, 1.41-1.56). Approximately 21.7% (95% CI, 19.1-24.4%) of all POP cases were attributable to central obesity. In addition, overweight without central obesity (BMI 25-29.9 and waist/height ratio less than 0.5) was associated with a 23% higher risk of POP (HR 1.23; 95% CI, 1.14-1.34), and this accounted for 2.0% (95% CI, 1.1-2.9%) of all POP cases. The magnitude of increased POP risk associated with central obesity varied by age (younger than 60 years vs 60 years or older: 57% vs 39%) and by history of hysterectomy (no vs yes: 54% vs 27%).CONCLUSIONCentral obesity and overweight without central obesity are risk factors for POP.","PeriodicalId":19483,"journal":{"name":"Obstetrics and gynecology","volume":null,"pages":null},"PeriodicalIF":7.2,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142490504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
