Albuminuria was quantified through urine albumin-to-creatinine ratio (uACR) and measures of vascular health included Aortic Augmentation Index (AIx), Pulse Wave Velocity (PWV) and Mean Arterial Pressure (MAP). Multivariable linear regression analyses estimated the association between uACR and each outcome, and sex was assessed as an effect modifier. Adults living with CKD were recruited from nephrology clinics in Calgary, Canada and 66 participants (39 female, 27 male) were included in this study. A higher eGFR (89[56] versus 58[50] ml/min/1.73m2) and lower uACR (32[405] versus 386[933] mg/g) were observed in females. Sex modified the relationship between uACR and AIx; with a positive association in females (<span><math><mrow><mi>β</mi></mrow></math></span> = 0.02; p &lt; 0.01), and no relationship in males (<span><math><mrow><mi>β</mi></mrow></math></span> = -0.004; p = 0.16). Positive relationships between uACR and both PWV and MAP were observed, though sex did not modify either relationship. Further research to elucidate the mechanisms underpinning these sex differences are necessary to optimize and personalize cardiovascular risk reduction strategies in CKD.</div></div>","PeriodicalId":72753,"journal":{"name":"Current research in physiology","volume":"8 ","pages":"Article 100145"},"PeriodicalIF":2.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143924663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
