Replacing 30 min of sedentary time with light-intensity PA lowered the odds to 0.81 (95% CI, 0.70–0.92, <i>p</i> = 0.001), whereas replacing it with moderate-to-vigorous PA reduced the odds to 0.28 (95% CI, 0.09–0.69, <i>p</i> = 0.002). Reducing sedentary time and increasing PA may contribute to the prevention of PTDM in LTRs.</p>","PeriodicalId":10467,"journal":{"name":"Clinical Transplantation","volume":"39 10","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ctr.70334","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
