Of those, 52% occurred among athletes in 24 schools situated in affluent communities, 15.6% occurred in 12 schools from average wealth communities, and 32.5% occurred in 12 schools located in disadvantaged communities. The largest injury rate was schools located in disadvantaged communities (3.3/1000 AE), followed by affluent (2.3/1000 AE) and average wealth (1.4/1000 AE) communities. On average, schools from affluent and disadvantaged communities had higher injury rates during competition than during practice (affluent: IRR=1.5, 95% CI=1.11, 2.05; disadvantaged: IRR=1.6, 95% CI=1.12, 2.41). Frequencies of many injury characteristics were consistent in schools across community-level socioeconomic status with contact, sprain/strain, and non-timeloss ranking highest in terms of injury mechanism, diagnosis, and time loss, respectively. Shoulder/clavicle was most frequent body part injured in schools in average and disadvantaged wealth communities, and ankle was most frequent in schools in affluent communities. Conclusions: Baseball athletes playing in schools located in disadvantaged wealth communities had the largest overall injury rate, followed by schools in affluent, and average wealth communities. Across most injury characteristics, a consistent trend emerged regardless of community-level disadvantage, with the highest baseball injury rates resulting from contact mechanisms, diagnosed as sprains or strains, and classified as non-time- loss injuries. While many injury patterns are consistent across socioeconomic communities, examining injuries through the lens of community-levels of disadvantage provides insight into subtle differences that could information targeted prevention strategies or resource needs.</p>","PeriodicalId":54875,"journal":{"name":"Journal of Athletic Training","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143587939","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}
