The prevalences of domain-specific impairments were estimated based on the results of norm-referenced tests, and the Montreal Cognitive Assessment (MoCA), Jak/Bondi criteria, Petersen criteria, and the National Institute on Aging and Alzheimer's Association (NIA-AA) criteria were used to diagnose MCI. NIA-AA criteria were also used to diagnose severe cognitive impairment. Generalized linear models and propensity score matching were used to compare prevalence estimates of cognitive impairment to a large sample of WTC-exposed-non-FDNY responders from the General Responder Cohort (GRC; <i>n</i> = 7102) who completed the MoCA during a similar time frame.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Result</h3>\u0000 \u0000 <p>Among FDNY responders under 65 years, the unadjusted prevalence of MCI varied from 52.57% to 60.32% depending on the operational definition of MCI, apart from using a conservative cut-off applied to MoCA total scores (18 < MoCA < 23), which yielded a markedly lower crude prevalence (24.31%) compared to alternative criteria. Using propensity score matching, the prevalence of MCI was significantly higher among WTC-exposed FDNY responders, compared to WTC-exposed GRC responders (adjusted <i>RR</i> = 1.13 (CI 95% = 1.07–1.20, <i>p</i> < 0.001), and descriptively higher than meta-analytic estimates from different global, community, and clinical populations. Following NIA-AA diagnostic guidelines, 4.96% of WTC-exposed-FDNY-responders met the criteria for severe impairments (95% CI = 2.91–7.82), a prevalence that remained largely unchanged after excluding responders over the age of 65 years.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Discussion</h3>\u0000 \u0000 <p>There is a high prevalence of mild and severe cognitive impairment among WTC-responders, highlighting the putative role of occupational, environmental, and disaster-related exposures in the etiology of accelerated cognitive decline.</p>\u0000 </section>\u0000 </di","PeriodicalId":7873,"journal":{"name":"American journal of industrial medicine","volume":"68 2","pages":"160-174"},"PeriodicalIF":2.7,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142827212","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}
