Analytic observational studies (cohort, case-control, and cross-sectional studies) with more than 30 participants per comparison group, evaluating the association between obesity and rotator cuff pathology, were eligible for inclusion. Meta-analysis was performed to quantitatively summarize associations between BMI and RCD to report odds ratios and corresponding 95% confidence intervals (CIs) for regression-based models and BMI mean differences between cases and controls.

Each 5-unit increase in BMI was associated with 35% greater odds of having rotator cuff tear (95% CI 1.06-1.71). In-depth assessment for risk of bias shows quality of studies varies greatly and highlights outcome heterogeneity, lack of temporality, confounding and selection bias as major concerns for individual studies.</p></div><div><h3>Conclusions</h3><p>In this study, we found a positive association between elevated BMI and RCD.</p></div><div><h3>Level of Evidence</h3><p>Level III, systematic review and meta-analysis of Level II-III studies.</p></div>","PeriodicalId":34631,"journal":{"name":"Arthroscopy Sports Medicine and Rehabilitation","volume":"6 4","pages":"Article 100953"},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666061X24000713/pdfft?md5=50e77e4ae54ad09170b10f1c60ec4a8c&pid=1-s2.0-S2666061X24000713-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142164517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
