Stratified by gender, hyperuricemia elevated the risk of MetS in both men (OR = 1.92, 95%CI 1.43-2.58, P<0.001) and women (OR = 2.13, 95%CI 1.62-2.8, P<0.001).</p><p><strong>Conclusions: </strong>This meta-analysis and systematic review robustly affirm a significant bidirectional association between MetS and hyperuricemia. The increased risk observed, especially in MUHOWO and across gender lines, underscores the clinical relevance. Addressing metabolic syndrome emerges as crucial in preventing and managing hyperuricemia, and vice versa. These findings offer valuable insights, urging further research into underlying mechanisms for more targeted interventions and personalized treatments in clinical practice.</p>","PeriodicalId":7578,"journal":{"name":"American Journal of Hypertension","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143603399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
